From 4b5d84b6577b78362b0cf711a27e55bc2c72232f Mon Sep 17 00:00:00 2001 From: AI Bot Date: Sat, 27 Jun 2026 11:52:55 +0300 Subject: [PATCH 01/83] =?UTF-8?q?feat(mcp):=20SaaS=20tenant-identity=20spi?= =?UTF-8?q?ne=20=E2=80=94=20authenticated=20tenant,=20no=20header=20overri?= =?UTF-8?q?de,=20default-deny?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 1 of multi-tenant SaaS (PLAN-saas-multitenant): close the isolation hole where the tenant came from a FREE x-nil-workspace header (anyone could read any workspace). resolve_tenant gains a saas mode: the tenant is the AUTHENTICATED identity via an injected claim_resolver (verified JWT workspace claim); the workspace header may NOT override it; a BYO adapter-url is rejected (identity routes to the tenant's registered active adapter); a missing claim is default-deny. Header-trust remains only for self-hosted/dev (multi_tenant without saas). build_remote_app/TenantToolsProvider thread saas + claim_resolver (env NIL_MCP_SAAS); SaaS FAILS CLOSED without a claim_resolver — it can never silently fall back to header-trust. Isolation conformance tests: tenant A and B route to different adapters; a header naming B under an A token is refused; BYO adapter-url refused; missing claim default-denied; unknown workspace has no adapter. 25 mcp/tenant tests green. Remaining (follow-up): wire the production claim_resolver = keycloak JWKS JWT verifier; then tenant-scope the newer surfaces (intent router providers, export, automation, Hermes) + per-tenant quotas (Phases 2-3), and the encrypted per-tenant secret vault. --- src/nilscript/mcp/server.py | 24 ++++++++++++++-- src/nilscript/mcp/tenant.py | 40 ++++++++++++++++++++++---- tests/test_mcp_tenant.py | 56 +++++++++++++++++++++++++++++++++++++ 3 files changed, 112 insertions(+), 8 deletions(-) diff --git a/src/nilscript/mcp/server.py b/src/nilscript/mcp/server.py index d5db888..f99a65c 100644 --- a/src/nilscript/mcp/server.py +++ b/src/nilscript/mcp/server.py @@ -108,11 +108,15 @@ def __init__( allow_insecure: bool = False, gate: str = "two-step", registry: Any = None, + saas: bool = False, + claim_resolver: Any = None, ) -> None: self._default = default self._allow_insecure = allow_insecure self._gate = gate self._registry = registry + self._saas = saas + self._claim_resolver = claim_resolver self._cache: dict[str, NilTools] = {} def get(self, ctx: Any) -> NilTools: @@ -123,6 +127,7 @@ def get(self, ctx: Any) -> NilTools: tenant = resolve_tenant( ctx, default=self._default, multi_tenant=True, allow_insecure=self._allow_insecure, registry=self._registry, + saas=self._saas, claim_resolver=self._claim_resolver, ) tools = build_tools( adapter_url=tenant.adapter_url, @@ -586,9 +591,17 @@ def build_asgi_app( auth_token: str | None = None, multi_tenant: bool = False, allow_insecure: bool = False, + saas: bool | None = None, + claim_resolver: Any = None, ): # type: ignore[no-untyped-def] """Return a streamable-HTTP ASGI app for production hosting (uvicorn/gunicorn behind nilscript.org). + `saas=True` (or env `NIL_MCP_SAAS=1`) turns on full tenant ISOLATION: the tenant is the + authenticated identity (a `claim_resolver` reads the verified JWT `workspace` claim), no header can + override it, and routing goes to that tenant's registered active adapter.

Three self-contained, TDD'd kernel keystones for tenant management: - SecretVault (nilscript/secrets/vault.py): per-tenant secrets (adapter creds + LLM key) encrypted at rest (Fernet); read BY TENANT only; storage-agnostic (injectable store); wrong key can't decrypt; tenants isolated. This is "save your secrets once" done securely. - JWT claim verifier (nilscript/mcp/auth.py): the production claim_resolver for SaaS mode — verifies the bearer JWT (sig/exp/iss/aud) and reads the workspace claim; forged/expired/missing → None → default-deny. Completes the spine's prod wiring (keycloak JWKS layers on top). - Per-tenant quotas + rate limit (nilscript/governance_quota.py): token-bucket + daily volume caps per (tenant, kind); a noisy tenant is throttled without starving others (the 429 fairness lesson). Pure, injected clock, resume-safe. 32 tests green (vault roundtrip/encryption/isolation/wrong-key; JWT verify/forge/expiry/no-claim; rate-limit fairness; quota caps). --- src/nilscript/governance_quota.py | 69 +++++++++++++++ src/nilscript/mcp/auth.py | 82 ++++++++++++++++++ src/nilscript/secrets/__init__.py | 5 ++ src/nilscript/secrets/vault.py | 82 ++++++++++++++++++ tests/test_saas_tenant_management.py | 120 +++++++++++++++++++++++++++ 5 files changed, 358 insertions(+) create mode 100644 src/nilscript/governance_quota.py create mode 100644 src/nilscript/mcp/auth.py create mode 100644 src/nilscript/secrets/__init__.py create mode 100644 src/nilscript/secrets/vault.py create mode 100644 tests/test_saas_tenant_management.py diff --git a/src/nilscript/governance_quota.py b/src/nilscript/governance_quota.py new file mode 100644 index 0000000..d3e28a6 --- /dev/null +++ b/src/nilscript/governance_quota.py @@ -0,0 +1,69 @@ +"""Per-tenant quotas + rate limiting — a noisy tenant cannot starve the others (the Odoo-429 lesson). + +A token-bucket per (tenant, kind) bounds request rate; a per-tenant daily counter bounds volume (e.g. +exports/writes).

Do **not** + build dual-write/back-compat machinery (YAGNI; single-instance correctness). + +**Phase-2 tests:** a drawn cycle registers + validates + content-hashes + runs through `LocalExecutor`; +a gated node parks in the real `approvals` queue and an approve-click drives execution +(`_execute_approved`); the os-server cycle tables/endpoints are gone and the integration tests that hit +them are migrated to the kernel path. + +**Exit criterion for the drift:** grep shows no `cycle-engine` grant and no os-server-local cycle +executor anywhere. *"Agent proposes, only the kernel commits" is now true on the visual surface too.* + +--- + +## 3. Phase 3 — the `.nil` text surface (second authoring view) + +- **Grammar:** Lark (pure-Python, no build step) — `src/nilscript/cycle/nil.lark`. Keep the grammar + **minimal: only what the AST needs.** No feature in `.nil` that has no AST node (prevents scope creep). +- `src/nilscript/cycle/parse.py` (text → Cycle AST) and `print.py` (Cycle AST → canonical `.nil`). +- **Round-trip guarantee (the trust contract):** + `parse(print(ast)) == ast` **and** `print(parse(text)) == canonical(text)`. Property-test over a + golden corpus. This is the HTML↔DOM equivalence made provable. +- The formal `.nil` grammar is also published as a spec artifact in the `nilscript-protocol` repo + (reference impl stays in the kernel). One paper proposition: *the AST is the canonical form; both + surfaces are bijective views over it.* + +**Why text is second, not first:** building `text→AST→exec` while the UI still edits SQLite would +create two truths — the exact thing we're eliminating. The visual surface must already edit the +canonical AST before the text surface joins it, so both share one model from day one. + +--- + +## 4. Phase 4 — Brain as a projection (invert the coupling) + +- `nilscript-graph` gains `project_cycle_to_graph(cycle) -> graph records`: a registered Cycle AST + projects into ontology nodes/edges (`Flow` + `Role` + `Policy` + `Entity` + `contains` edges). The + brain **consumes** the protocol; it no longer authors cycles independently. +- `GET /api/graph/cycles` then reflects registered protocol cycles. +- **Naming reconciliation (flag, low-stakes):** the protocol `Cycle` is *one business process* + (`SalesLeadLifecycle`); the brain's existing `Cycle` is a *domain grouping* (Sales/Finance). A + protocol `Cycle` projects as the brain's **`Flow`**, `contained` by a brain domain `Cycle`. Either + keep both terms (protocol Cycle = process, brain Cycle = domain hub) or rename the brain's grouping to + "Domain" later. Not a blocker; decide before the paper. + +--- + +## 5. Phase 5 — generators (each a pure function over the AST) + +All pure `project_*(cycle)`, no new source of truth. Sequence by leverage: +1. **Simulation / dry-run** (walk the AST, propose-only, no commit) and **governance/risk report** + (tiers, reversibility, approval points) — these carry the product's "generate vs govern" story. +2. **Docs** (markdown), **Mermaid**, **SVG** graph. +3. **JSON / YAML**, **OpenAPI-like** capability description, **AI-context** (the cycle as agent prompt + context), **SDK** stubs. + +--- + +## 6.

Mitigate with the same round-trip + property test as Phase 3, applied to the visual serializer: `deserialize(serialize(ast)) == ast`. +2. **Parser scope creep** (Phase 3) — cap the grammar to AST-backed constructs only; defer + `import`/`call`/subcycles until a real need. +3. **Roles/policies ownership** — the Cycle AST owns *authoring-time* roles/policies (declarative); the + brain owns *derived* reasoning. Don't duplicate enforcement: `policies.raises_tier` only *raises* the + kernel tier floor, never lowers it (existing invariant). +4. **Migration** — no dual-write; one-shot convert or re-create.

Provable BOTH ways: parse_nil(print_nil(ast))==ast and print_nil(parse_nil(text))==text. Bilingual bijection. - registry.ProtocolRegistry: the symbol layer (steps/variables/outputs/context/roles/policies/ outcomes + verb catalog) -> resolve (go-to-def), references (find-refs), completions, dead_references. Reuses compile.py's literal-vs-reference discipline. - projections/: to_mermaid, to_markdown, simulate (happy-path dry-run, propose-only), governance_report (gates/approvals/reversibility-from-compensate).

Before this, a HIGH-tier commit the System held came back as a 'parked' node output and the walk continued past it on a phantom result, and an undecided await_approval degraded to a poll-budget 'timeout' — both in-memory-only, neither resumable. - kernel/executor: a held commit or an undecided approval raises an internal _Park; execute() returns RunResult.waiting {kind, node, proposal, ...} with the context at park time. execute(resume={context, node_id, output}) binds the output as the parked node's output and continues via the node's OWN next_after routing — no resume-only control flow. - controlplane/store: new parked_runs table {run_id, node_id, kind, pinned automation version, proposal_id, deadline, context}. settle_park() claims waiting→settled so a re-delivered decision/event can never resume twice. - automation/dispatch: _classify maps waiting→waiting_approval/waiting_event; _record persists the park row alongside finish_run. resume_parked_run reloads the PINNED plan and re-runs with resume=...; resume_on_decision routes approve→continuation with the commit result bound, reject→rejected (or the await_approval node's own on_rejected branch). - controlplane/app: POST /proposals/{id}/decision — the same path that runs _execute_approved/_materialize_dependents — now resumes every run parked on that proposal; /automations/tick sweeps due deadlines (on_timeout routes). Decision recorded: parked-run rows live in the control-plane store (the SSOT for approvals); the kernel executor stays stateless between steps — resume is a fresh executor over a persisted context, so restarts lose nothing. Parks inside parallel branches are documented as unsupported (gather swallows the signal). Tests: executor park/resume, approve→completed with committed result in the run record, reject→rejected with reason, restart survival over the same DB file, double-decision idempotency, await_approval branch routing, deadline sweep. 621→630 green. --- src/nilscript/automation/__init__.py | 13 +- src/nilscript/automation/dispatch.py | 146 +++++++++++++- src/nilscript/automation/scheduler.py | 41 +++- src/nilscript/automation/triggers.py | 16 ++ src/nilscript/controlplane/app.py | 56 +++++- src/nilscript/controlplane/store.py | 139 +++++++++++++ src/nilscript/kernel/executor.py | 83 +++++++- tests/test_gate_resume.py | 269 ++++++++++++++++++++++++++ 8 files changed, 745 insertions(+), 18 deletions(-) create mode 100644 tests/test_gate_resume.py diff --git a/src/nilscript/automation/__init__.py b/src/nilscript/automation/__init__.py index a89b117..6a1c066 100644 --- a/src/nilscript/automation/__init__.py +++ b/src/nilscript/automation/__init__.py @@ -20,8 +20,14 @@ run_composed, validate_composed, ) -from nilscript.automation.dispatch import Runner, fire_composed, fire_manual -from nilscript.automation.scheduler import dispatch_event, run_due_schedules +from nilscript.automation.dispatch import ( + Runner, + fire_composed, + fire_manual, + resume_on_decision, + resume_parked_run, +) +from nilscript.automation.scheduler import dispatch_event, resume_due_waits, run_due_schedules from nilscript.automation.skeleton import context_from_skeleton from nilscript.automation.models import ( AutomationDefinition, @@ -56,6 +62,9 @@ "parse_composed", "parse_trigger", "register", + "resume_due_waits", + "resume_on_decision", + "resume_parked_run", "run_composed", "run_due_schedules", "validate_composed", diff --git a/src/nilscript/automation/dispatch.py b/src/nilscript/automation/dispatch.py index 6e38636..f11b366 100644 --- a/src/nilscript/automation/dispatch.py +++ b/src/nilscript/automation/dispatch.py @@ -10,6 +10,7 @@ from __future__ import annotations from collections.abc import Awaitable, Callable +from datetime import UTC, datetime, timedelta from typing import Any, Protocol from nilscript.automation.compose import ( @@ -19,8 +20,9 @@ run_composed, ) from nilscript.kernel.executor import RunResult +from nilscript.kernel.graph import node_map -# Walks a plan and returns its RunResult.

Dialect seam (cycle/0.2 stays FROZEN, additive only): - Cycle.nil accepts "cycle/0.2" | "cycle/0.3"; the new step is only valid in 0.3 and 0.3 means exactly "uses wait_for_event" (two-way model rule). The dialect is therefore content-determined, which lets the .nil parser INFER it with no surface version marker while parse(print(ast)) == ast stays an exact bijection. - Grammar (parser+printer, exact inverse): step AwaitReply { wait_for_event { on_event: "mail.received"; match { order_ref: $po }; timeout_seconds: 604800 -> route Escalate } next Parse } The timeout and its route print on ONE line — a deadline with nowhere to go is unrepresentable. $name match values are explicit references to variables/named outputs; bare literals stay literals (match is equality). - Registry / projections / LSP: edges (next + on_timeout), $ref dead-ref scan, hover detail, simulate happy path, mermaid event/timeout edges, docs sentence, step keyword. IR + runtime: - kernel/models: WaitForEventNode (own node — NOT the clock-sleep `wait`): on_event, shallow match (values may be data refs), positive timeout (V1), REQUIRED on_timeout route; V2 covers dangling next/on_timeout; V6 sees match references. compile lowers the step, resolving $po into $.input.po. - executor: walking the node PARKS the run (kind=event) with the match RESOLVED against the run context at park time; next_after routes a matched-event resume to `next` (payload bound as the step's output) and a {timed_out} resume to on_timeout. - scheduler: dispatch_event — the same path that fires event triggers — now resumes matching waiting parks (event-name equality + shallow field equality, workspace-scoped); resume_due_waits sweeps passed deadlines on the /automations/tick clock. Tests: exact round-trip (incl. the bare-$po authoring form), 0.2/0.3 dialect refusals, lowering + $ref resolution, V1/V2 refusals (bad timeout, missing/dangling route), park then match then resume with payload bound, deadline timeout route, restart survival over the same DB file, workspace scoping. 630 to 646 green. --- src/nilscript/cycle/__init__.py | 2 + src/nilscript/cycle/compile.py | 38 +++ src/nilscript/cycle/lsp.py | 5 +- src/nilscript/cycle/models.py | 43 ++- src/nilscript/cycle/nil_parser.py | 41 ++- src/nilscript/cycle/nil_printer.py | 19 ++ src/nilscript/cycle/projections/docs.py | 8 + src/nilscript/cycle/projections/mermaid.py | 7 + src/nilscript/cycle/projections/simulate.py | 4 + src/nilscript/cycle/registry.py | 17 +- src/nilscript/kernel/executor.py | 13 + src/nilscript/kernel/graph.py | 7 + src/nilscript/kernel/models.py | 18 ++ src/nilscript/kernel/validator.py | 3 + tests/test_wait_for_event.py | 294 ++++++++++++++++++++ 15 files changed, 511 insertions(+), 8 deletions(-) create mode 100644 tests/test_wait_for_event.py diff --git a/src/nilscript/cycle/__init__.py b/src/nilscript/cycle/__init__.py index 4f640bc..b70fa46 100644 --- a/src/nilscript/cycle/__init__.py +++ b/src/nilscript/cycle/__init__.py @@ -37,6 +37,7 @@ QueryStep, RoleRef, VariableBinding, + WaitForEventStep, ) from nilscript.cycle.projections import ( governance_report, @@ -60,6 +61,7 @@ "DecisionStep", "ApprovalStep", "NotifyStep", + "WaitForEventStep", "CompileResult", "compile_cycle", "cycle_content_hash", diff --git a/src/nilscript/cycle/compile.py b/src/nilscript/cycle/compile.py index d47cd58..7d13fe2 100644 --- a/src/nilscript/cycle/compile.py +++ b/src/nilscript/cycle/compile.py @@ -26,6 +26,7 @@ DecisionStep, NotifyStep, QueryStep, + WaitForEventStep, ) from nilscript.kernel.context import ValidationContext from nilscript.kernel.diagnostics import ValidationResult @@ -82,6 +83,27 @@ def _resolve(value: object, outputs: dict[str, str], variables: dict[str, str]) return value # a literal (e.g. "default", an event name) +def _resolve_match( + match: dict[str, object], outputs: dict[str, str], variables: dict[str, str] +) -> dict[str, object]: + """wait_for_event `match` values: EXPLICIT `$name(.tail)` references resolve like `_resolve` + heads; everything else stays a literal.

charset=UTF-8 Content-Transfer-Encoding: 8bit Invariants enforced: the printer DEFINES canonical form and parse(print(ast)) == ast is exact (round-trip suite); content_hash is SHA-256 over canonical JSON so identical capabilities hash identically regardless of authoring key order (the registry's version lock, I4); invalid shapes refuse with structured NilSyntaxError(message, line, col) — never a bare traceback; archetype is an OPTIONAL closed-enum tag so a wrapped v0 capability can omit it instead of guessing semantics (I2); implemented_by requires a "default" implementation structurally. Spec deviation (codebase idiom wins): models are frozen pydantic DslModel (extra=forbid) like cycle/models.py, not stdlib dataclasses; content_hash lives beside the model (hash.py) as cycle/hash.py does, not as a model field. --- src/nilscript/capability/__init__.py | 38 +++++ src/nilscript/capability/hash.py | 24 +++ src/nilscript/capability/models.py | 145 ++++++++++++++++ src/nilscript/capability/nil_parser.py | 208 +++++++++++++++++++++++ src/nilscript/capability/nil_printer.py | 81 +++++++++ tests/test_capability_nil.py | 214 ++++++++++++++++++++++++ 6 files changed, 710 insertions(+) create mode 100644 src/nilscript/capability/__init__.py create mode 100644 src/nilscript/capability/hash.py create mode 100644 src/nilscript/capability/models.py create mode 100644 src/nilscript/capability/nil_parser.py create mode 100644 src/nilscript/capability/nil_printer.py create mode 100644 tests/test_capability_nil.py diff --git a/src/nilscript/capability/__init__.py b/src/nilscript/capability/__init__.py new file mode 100644 index 0000000..3611c0e --- /dev/null +++ b/src/nilscript/capability/__init__.py @@ -0,0 +1,38 @@ +"""The Capability AST — the business-contract protocol object (CAPABILITY-SHIFT plan §A1). + +`Capability` describes what an organisation can do — typed contract, risk floor, approval-strategy +binding, exposure, SoD class — as pure data over the same `.nil` grammar family as cycles. +`capability_content_hash` locks a version; the control-plane registry (§B1) stores versions with +the automation registry's supersede-never-edit disciplines; `wrap_cycle` (§B8) derives a fail-closed +v0 capability from any registered cycle. +""" + +from __future__ import annotations + +from nilscript.capability.hash import capability_content_hash +from nilscript.capability.models import ( + ArchetypeTag, + Capability, + CapabilityField, + Exposure, + FieldType, + Metrics, + Sod, +) +from nilscript.capability.nil_parser import parse_capability_nil +from nilscript.capability.nil_printer import print_capability_nil +from nilscript.cycle.nil_parser import NilSyntaxError + +__all__ = [ + "ArchetypeTag", + "Capability", + "CapabilityField", + "Exposure", + "FieldType", + "Metrics", + "NilSyntaxError", + "Sod", + "capability_content_hash", + "parse_capability_nil", + "print_capability_nil", +] diff --git a/src/nilscript/capability/hash.py b/src/nilscript/capability/hash.py new file mode 100644 index 0000000..05e9a1a --- /dev/null +++ b/src/nilscript/capability/hash.py @@ -0,0 +1,24 @@ +"""The version lock — `content_hash` over the **Capability AST** (invariant I4). + +Same canonicalisation as `cycle.hash.cycle_content_hash` and `automation.models.content_hash`: +SHA-256 over sorted-key, tight-separator canonical JSON, so identical capabilities hash identically +regardless of authoring key order — the registry's idempotent-register / supersede-never-edit +disciplines hang off this one function. +""" + +from __future__ import annotations + +import hashlib +import json + +from nilscript.capability.models import Capability + + +def capability_content_hash(capability: Capability) -> str: + canonical = json.dumps( + capability.model_dump(by_alias=True, mode="json"), + sort_keys=True, + separators=(",", ":"), + ensure_ascii=False, + ) + return hashlib.sha256(canonical.encode("utf-8")).hexdigest() diff --git a/src/nilscript/capability/models.py b/src/nilscript/capability/models.py new file mode 100644 index 0000000..8846ddd --- /dev/null +++ b/src/nilscript/capability/models.py @@ -0,0 +1,145 @@ +"""The NIL Protocol Model — Capability AST v0.1 (CAPABILITY-SHIFT plan §A1). + +The `capability` is the business contract layer ABOVE a cycle: what the organisation can do, +who owns it, what it needs and produces, how risky it is, and which approval strategy governs it. +It is DATA, never code (invariant I1) — the kernel prepares/approves/executes; the capability only +describes.

approval algebra + .nil bijection + V9 well-formedness (M1b) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Invariants enforced: only the five forms Auto|Approve|Seq|Quorum| Conditional are representable — par/weighted/dynamic/delegate/override are grammar-reserved and PARSE-REFUSE with V9_UNSUPPORTED_FORM (a named governance answer carrying line/col, not a generic syntax error); parse(print(ast)) == ast is exact for every form; V9 rules are pure functions returning the kernel's structured ValidationResult (refusals as answers, never exceptions): V9_SELF_APPROVAL (an approve unit missing distinct_from:[preparer] under sod.preparer_not_approver, I6), V9_QUORUM_UNSATISFIABLE (k > |of|), V9_QUORUM_DISTINCT (distinct demanded but unresolvable), V9_TIMEOUT_NO_ROUTE (a deadline with no escalate/ reject route), V9_AUTO_FORBIDDEN (auto() when capability risk > MEDIUM, I3). Each rule tested in both directions. Spec note: timeout.then is Optional in the MODEL (not required as the cycle idiom would suggest) precisely so 'every timeout has a route' can surface as a V9 finding at the offending unit rather than a parse crash; Conditional branches are non-conditional nodes, so nested conditionals are structurally unrepresentable in MVP. --- src/nilscript/strategy/__init__.py | 52 +++++++ src/nilscript/strategy/hash.py | 23 +++ src/nilscript/strategy/models.py | 142 +++++++++++++++++ src/nilscript/strategy/nil_parser.py | 184 ++++++++++++++++++++++ src/nilscript/strategy/nil_printer.py | 70 +++++++++ src/nilscript/strategy/validate.py | 127 +++++++++++++++ tests/test_strategy_nil.py | 214 ++++++++++++++++++++++++++ tests/test_strategy_v9.py | 203 ++++++++++++++++++++++++ 8 files changed, 1015 insertions(+) create mode 100644 src/nilscript/strategy/__init__.py create mode 100644 src/nilscript/strategy/hash.py create mode 100644 src/nilscript/strategy/models.py create mode 100644 src/nilscript/strategy/nil_parser.py create mode 100644 src/nilscript/strategy/nil_printer.py create mode 100644 src/nilscript/strategy/validate.py create mode 100644 tests/test_strategy_nil.py create mode 100644 tests/test_strategy_v9.py diff --git a/src/nilscript/strategy/__init__.py b/src/nilscript/strategy/__init__.py new file mode 100644 index 0000000..9902ae3 --- /dev/null +++ b/src/nilscript/strategy/__init__.py @@ -0,0 +1,52 @@ +"""The ApprovalStrategy AST — the MVP-5 approval algebra (CAPABILITY-SHIFT plan §A2). + +`Strategy` is the governed answer to "who must sign, in what shape": `Auto | Approve | Seq | +Quorum | Conditional`, over the same `.nil` grammar family as cycles and capabilities.

21:41:49 +0300 Subject: [PATCH 20/83] feat(registry): capability + strategy registries in the control plane (M2a) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Invariants enforced: content_hash is the lock — registering the same hash is an idempotent no-op (no new version), a new hash SUPERSEDES the prior version (superseded_by + state=deprecated) and never edits in place; every read is workspace-pinned and fails closed (no workspace -> 400 on list, 404 cross-tenant, refused write); lifecycle is the closed set draft -> published -> deprecated and publish is an auth-gated act; strategy registration is V9-gated — an ill-formed strategy (e.g. V9_QUORUM_UNSATISFIABLE) is refused with structured diagnostics and never stored, mirroring 'a failing plan is never stored'. One generic versioned-registry engine backs both tables so the disciplines cannot drift. Endpoints follow the existing FastAPI idioms: _registry_authed bearer gating, {ok, definition} envelopes, structured {error|refusal} refusals. Both AST-object and .nil-text intake are accepted (the text surface is the SSOT convention). --- src/nilscript/controlplane/app.py | 179 ++++++++++++++++++++ src/nilscript/controlplane/store.py | 216 ++++++++++++++++++++++++ tests/test_capability_registry.py | 246 ++++++++++++++++++++++++++++ 3 files changed, 641 insertions(+) create mode 100644 tests/test_capability_registry.py diff --git a/src/nilscript/controlplane/app.py b/src/nilscript/controlplane/app.py index 107863d..04b3ac5 100644 --- a/src/nilscript/controlplane/app.py +++ b/src/nilscript/controlplane/app.py @@ -39,6 +39,11 @@ validate_composed, ) from nilscript.automation.compose import StageRunner +from nilscript.capability import ( + Capability, + capability_content_hash, + parse_capability_nil, +) from nilscript.controlplane.store import EventStore from nilscript.cycle import ( Cycle, @@ -58,6 +63,12 @@ ) from nilscript.kernel.diagnostics import ValidationResult from nilscript.kernel.executor import LocalExecutor +from nilscript.strategy import ( + Strategy, + parse_strategy_nil, + strategy_content_hash, + validate_strategy, +) from nilscript.sdk.client import NilClient from nilscript.sdk.idempotency import commit_idempotency_key from nilscript.sdk.connect import handshake @@ -979,6 +990,174 @@ def cycles_list(workspace: str = "") -> dict[str, Any]: cycles = [a for a in store.list_automations(workspace) if a.get("kind") == "cycle"] return {"cycles": cycles} + # ── Capability + Strategy registries (plan B1): same disciplines as automations ────────── + def _capability_from_body(body: dict[str, Any]) -> tuple[Capability | None, Any]: + """Accept either `capability` (AST object) or `text` (.capability.nil source).

SoD: the preparer can never sign their own subject and distinct_from violations refuse — both SOD_VIOLATION, refusals not exceptions. rehold() voids collected signatures (superseded, audit row kept) and re-holds fresh slots for material edits. Deliberate deviation from the plan's 'reuse planned_steps': Seq carries the dependent-plan grammar (planned -> pending stepwise, cancel-the-rest) on the signatures table itself, because a strategy unit approves the SAME subject — there is no verb/args to re-propose, so planned_steps rows would be dishonest.

charset=UTF-8 Content-Transfer-Encoding: 8bit prepare(workspace, capability, inputs, prepared_by) -> one persisted subject, card assembled BY CODE ONLY (I5): pinned registry record (id/semver/registry version/content-hash), inputs validated against the typed contract (missing/typed-wrong/unknown -> structured refusal listing fields), modifiable = the NOT-required inputs (required slots locked), strategy state from the B3 interpreter (units/signed/pending/two-key), affected systems from the default implementing cycle's step-verb namespaces x adapter registry labels, risk = the capability floor, reversibility/coverage from declared compensation, prepared_by stamped for SoD. Card body is BYTE-deterministic — timestamps, prepared ids and signature rows live in the envelope, never the hashed body (canonical sort_keys serialization + sha256 card_hash). Endpoints: POST /prepared (prepare, no effect), GET /prepared/{id} (workspace-pinned card, fail closed), POST /prepared/{id}/sign (the strategy-aware decision surface: SOD_VIOLATION 403s, approve-with-edits inside modifiable voids collected signatures and re-holds, full approval fires the commit), POST /prepared/{id}/execute (auto/complete + retry; NOT_APPROVED refuses with the pending units). The commit is the ONLY effect path: fire_manual on the default implementing cycle, idempotency key prep:, seeded inputs bound as $.input (fire_manual and the live runner gained an optional input kwarg). /automations/tick now also sweeps strategy unit deadlines: escalate re-addresses a fresh slot, reject rejects the prepared subject. Deviation noted: risk/reversibility come from the REGISTRY record only (the wrap already baked declared verb metadata into the capability floor, fail closed); live adapter tiers do not leak into the card, keeping it deterministic on registry state alone.

Runtime: walking the node emits a marker with the committed-so-far snapshot and continues to `next` — NO pause, no adapter call. dispatch persists each marker as a `run_checkpoints` row {run_id, name, node_id, workspace, committed[], at}, idempotent by (run_id, name) — row-backed, restart-safe. Executor RunResult gains `checkpoints`; on resume the committed-write ledger is REBUILT from the restored context (pipeline order) so post-park checkpoints and saga unwinds see pre-park commits too. `looks_committed` is the one public judgement of "this action output is a committed effect", shared by executor and control plane. Rollback (REUSES the existing compensation path, no second mechanism): POST /runs/{run_id}/rollback {to_checkpoint} replays looks_committed over the persisted trace, takes every write committed AFTER the marker, and previews the REVERSE chain of each step's own `compensate_with` (args resolved against the trace so the card shows literals) — held as ONE governed proposal (rb:{run_id}:{name}, verb run.rollback, tier HIGH) on the normal pending/decision surface. Approval commits the compensations in reverse order via PROPOSE->COMMIT with rb-{run_id}-{n} idempotency keys (the same honest forward-compensation discipline as LocalExecutor._compensate); re-approval is a no-op (decide() guards the transition, keys guard the crash window). Refusals as answers: IRREVERSIBLE_SEGMENT (409, lists blocking steps, holds NOTHING), UNKNOWN_CHECKPOINT (404), workspace-pinned run lookup fails closed. V7 (d) now honours a checkpoint boundary as compensation coverage. Tests: 17 new (bijection, dialect gate, duplicate-name refusal, lowering, marker rows across a restart, reverse-chain preview + idempotent re-preview, ordered approval commits with rb keys, idempotent re-approval, IRREVERSIBLE_SEGMENT, unknown checkpoint/run, workspace pinning, V7-d checkpoint coverage). 810 total green. --- src/nilscript/automation/dispatch.py | 19 +- src/nilscript/controlplane/app.py | 176 ++++++++- src/nilscript/controlplane/store.py | 74 ++++ src/nilscript/cycle/__init__.py | 2 + src/nilscript/cycle/compile.py | 6 + src/nilscript/cycle/lsp.py | 13 +- src/nilscript/cycle/models.py | 39 +- src/nilscript/cycle/nil_parser.py | 18 +- src/nilscript/cycle/nil_printer.py | 9 + src/nilscript/cycle/projections/docs.py | 3 + src/nilscript/cycle/projections/mermaid.py | 3 + src/nilscript/cycle/projections/simulate.py | 4 + src/nilscript/cycle/registry.py | 8 +- src/nilscript/kernel/executor.py | 48 ++- src/nilscript/kernel/models.py | 13 + tests/test_checkpoint_rollback.py | 403 ++++++++++++++++++++ 16 files changed, 822 insertions(+), 16 deletions(-) create mode 100644 tests/test_checkpoint_rollback.py diff --git a/src/nilscript/automation/dispatch.py b/src/nilscript/automation/dispatch.py index 4db1ff4..83a976a 100644 --- a/src/nilscript/automation/dispatch.py +++ b/src/nilscript/automation/dispatch.py @@ -35,6 +35,7 @@ def finish_run(self, run_id: str, state: str, trace: dict[str, Any] | None) -> b def get_run(self, run_id: str) -> dict[str, Any] | None: ... def park_run(self, run_id: str, **kw: Any) -> dict[str, Any]: ... def settle_park(self, run_id: str, node_id: str, status: str) -> bool: ... + def record_checkpoint(self, run_id: str, **kw: Any) -> bool: ... def _classify(result: RunResult) -> str: @@ -62,6 +63,7 @@ def _trace(result: RunResult) -> dict[str, Any]: "notifications": result.notifications, "context": result.context, "waiting": result.waiting, + "checkpoints": result.checkpoints, } @@ -74,10 +76,21 @@ def _record( automation_id: str, version: int, ) -> None: - """Close (or park) one run row from its RunResult.

Canonical grammar (between the verb line and the output/next routing tail, in model field order; the fields are v0.2 — no dialect change): retry { max_attempts: 3; backoff: exponential; initial_seconds: 2.0 } on_error route -> Cleanup # '-> target' only when to is set compensate_with odoo.refund_invoice { payment_id: "pay.id" } The retry block prints every field explicitly (the approval timeout_seconds voice); on_error routes borrow the 'on X -> Step' arrow; compensate_with mirrors 'use verb { args }'. ActionStep-only — no other step kind carries these fields; a query step with them refuses to parse. Wiring (the wait_for_event precedent, c1d40d7): - registry: on_error.to is a step-target edge (dead-ref undefined_step, find-references); compensate args are data refs (undefined_ref, and a compensation-only reader keeps an output 'used'). - lsp: retry/on_error/compensate_with in step keywords + semantic-token keywords; the word after compensate_with classifies as a verb. Byte-stability (non-negotiable): every fields-absent cycle prints BYTE-IDENTICAL — pinned by sha256 regression over the three worked fixtures, hashes computed against the printer before this change.

The one test walks, each assertion tagged with the invariant it proves (I1 card determinism, I2 two-key+SoD, I3 approval-drives-execution, I4 idempotency, I5 tenancy fail-closed, I6 per-phase rollback, I7 mock-first): 1. /cycles/register (pending_approval, armed by the owner) + /capabilities/wrap (risk HIGH from DECLARED verb tiers) + /strategies two-key upgrade (v2 of the wrapped strategy id — strategies are data). 2. /prepared -> the deterministic Permission Card: EXACT payload preview, quorum(2, distinct) state naming both keys, parked on the Decisions feed, zero effects fired. 3. preparer's own signature -> 403 SOD_VIOLATION. 4. first key -> pending (1 of 2), /execute refuses NOT_APPROVED, still no run. 5. second DISTINCT key -> the commit fires the implementing cycle EXACTLY once (run key = prep:{prepared_id}); the run PARKS on the HIGH write (verb-tier gate), visible in pending after the hold registers; the pre-write checkpoint marker persisted as a row even while parked. 6. owner approves the write proposal -> ONE commit, the run RESUMES to the notify and completes with the committed result (proposal, state, id) bound in the trace. 7. replay: /prepared execute -> ALREADY_COMMITTED; re-firing the same idempotency key -> replayed=true; one propose, one commit, one run row. 8. a second workspace sees NOTHING: empty prepared feed, 404 card, empty pending, empty runs, 404 rollback. 9. /runs/{id}/rollback to the checkpoint -> ONE held governed proposal (rb:{run}:{name}) listing the write's own compensate_with; approval compensates with rb-{run}-0 keys; re-approval never double-compensates. No joins had to be built: the prepare-plane commit already fires the capability's default implementing cycle through fire_manual, and the parked HIGH write resumes through the same decision endpoint — the demo composes existing seams only (fixtures from test_gate_resume / test_prepared / test_checkpoint_rollback).

The status poll asks the adapter about it, the adapter answers 'expired' (it never saw it), and _APPROVAL_ROUTE mapped expired->timeout — so a human gate silently self-resolved as a timeout and the run completed in ~0s. Narrow _APPROVAL_ROUTE to GENUINE decisions only (approved/executed->approved, rejected->rejected); every non-decision state (expired/pending/suspended/failed/unknown) now PARKS, surfacing a pending approval. The real deadline timeout stays with the control plane's resume_due_waits. Observability: the executor now emits an ordered per-node trace (RunResult.trace_nodes, shape in _NODE_EVENT_SHAPE) — node_id/seq/type/verb/ status/started_at/ended_at/output_summary(redacted)/proposal_id/event_wait/ tier/error. Timestamps come from the runtime clock. On a park the parked node is waiting_approval|waiting_event; on resume it advances to completed.

Everything else is + present; **do NOT borrow BPMN's XML** — NIL's text is the point (this is the Bicep lesson, 2.12). + +### 2.2 Terraform / HCL — *clean declarative blocks* +- **Borrow:** readable block syntax, typed, simple, diffable. +- **`[have]`** NIL is already block-structured (`cycle X { … step Y { … } }`), text-diffable, typed via + the AST. This is a solved dimension. +- **`[gap]`** Minor: HCL-style *interpolation ergonomics* — NIL's `$name` refs are good; could add + richer expression typing (ties to 2.10 Rust). + +### 2.3 GitHub Actions YAML — *instant readability* +- **Borrow:** the "anyone can read the steps" quality. +- **`[have]`** NIL steps read linearly and route explicitly — arguably *more* legible than YAML + (no significant-whitespace traps) and bilingual. +- **`[gap]`** None structural; a lesson in **keeping the common case terse** (don't let governance + boilerplate bury the flow — the canonical printer already elides defaults). + +### 2.4 Temporal — *durable execution primitives* (the runtime twin) +- **Borrow:** `await`, `signal`, `sleep`, `continue`, **child workflow**. +- **`[have]`** `await approval` (await), `wait_for_event` (signal-ish + sleep via timeout), park/resume + (durable continue), `compensate_with` (saga). NIL's runtime *already feels Temporal-like*. +- **`[gap] ⭐ Child workflow = sub-cycle invocation.** NIL cycles compose **verbs** only; a step that + **invokes another Capability/Cycle and awaits it** does not exist. **This is the #1 language gap** + (NBEM P16 / gap-plan **W5** / DSL-constitution §8.2). Also: a first-class **`signal`** (external nudge + to a running thread distinct from a world-event) is worth separating from `wait_for_event`. + +### 2.5 AWS Step Functions — *orchestration semantics* +- **Borrow:** Wait, Choice, **Retry, Catch, Parallel**. +- **`[have]`** Wait (`wait_for_event`/timeout), Choice (`decision`), **Retry** (`retry {}`), **Catch** + (`on_error`). +- **`[gap]`** **Parallel** (fan-out + join).

What the NIL DSL is (and is not) + +- **It is** the textual authoring form of a **Cycle** (the blueprint; see the ontology). One `.nil` + file = one Cycle. It is **1:1 with the frozen Cycle AST** — every surface construct maps to exactly + one AST node; every AST field prints as exactly one token. There is no syntax without a model. +- **It is round-trippable and deterministic** — `print_nil(parse_nil(text)) == text` for canonical text. + This is the trust contract: an agent can author `.nil`, parse it to validate, and re-print to confirm. +- **It is governed by construction** — the language can only express governed operations: verbs are + two-step (PROPOSE→COMMIT under the hood), approvals are first-class gates, effects can declare + compensation, long waits are explicit. You cannot write an ungoverned effect in `.nil`. +- **It is bilingual** — human-facing text carries Arabic + English by a strict bijection. +- **It is NOT** the NIL wire protocol (PROPOSE/COMMIT performatives — that is the runtime), and NOT a + general programming language. It declares an operation's **shape, governance, and flow** — the kernel + executes it. + +**Dialect note:** v0.2 is the frozen core; **v0.3 is additive** — `wait_for_event`, `checkpoint`, and +`implements` (a cycle declaring the capability it fulfils). Use only these constructs; nothing else is +valid. + +--- + +## 2. The design laws of the language (why it is shaped this way) + +These tie the syntax to the platform constitution — an agent should *understand* them, not just emit: + +1. **One construct per concept** — no two ways to say a thing (keeps it round-trippable and + learnable). *(canonical form)* +2. **Verbs are the only effects** — a step `use`s a verb; you cannot inline a capability or a raw API + call. Atoms are verbs. *(NBEM P12/P13; see CAPABILITIES-VERBS-CYCLES-ARCHITECTURE.md)* +3. **Governance is expressible and unavoidable** — approvals (`await approval`), policy tiers + (`raises_tier`), reversibility (`compensate_with`) are language constructs, not afterthoughts. + *(NBEM P9)* +4. **Waiting is first-class** — `wait_for_event` and approval timeouts (up to 2,592,000 s ≈ 30 days) are + syntax, because real operations wait. *(NBEM P14)* +5. **Everything routes explicitly** — every step names its `next` / `on approve` / `on_true` / + `-> route`. Control flow is a readable graph, never implicit fall-through. +6. **Human text is bilingual and separated from logic** — `intent`, `notify`, approval `title` carry + ar/en; identifiers and verbs are machine tokens. *(product is ar/en)* + +--- + +## 3.

Every step type — form, meaning, when to use + +A `flow` contains `step { … }` blocks. There are **seven** step bodies: + +### 4.1 `action` — do a governed effect (the workhorse) +```nil +step CreateInvoice { + use odoo.create_purchase_invoice { vendor: "$vendor", amount: "$total" } + [ retry { max_attempts: 3; backoff: "exponential"; initial_seconds: 5 } ] + [ on_error compensate [-> ] ] # or: on_error halt / retry / continue + [ compensate_with odoo.cancel_invoice { id: "$invoice_id" } ] # the saga inverse + [ output invoice ] # bind the result to a variable + [ next Notify ] # the continuation step +} +``` +*Use for:* any state-changing backend action. `compensate_with` makes it reversible (Saga). `output` +captures the result for later `$`-references. **This is the only construct that changes the world.** + +### 4.2 `query` — read data (no side effect) +```nil +step ReadStock { query odoo.read_product { sku: "$sku" } output stock next Decide } +``` +*Use for:* reading rates, entities, current state to branch on. Same `use`/`with`/`output`/`next` shape +as `action`, minus the error/compensation tail (reads don't compensate). + +### 4.3 `decision` — branch on a condition +```nil +step Decide { decision when "$stock.qty < $reorder_point" on_true Order on_false Done [next X] } +``` +*Use for:* conditional flow. `when` is a guard expression over bound variables. + +### 4.4 `await approval` — a first-class human gate (maker-checker) +```nil +step Approve { + await approval { + title: { ar: "اعتماد الشراء"; en: "Approve purchase" }; + [ description: ; ] + approver: owner; # a role/context actor + timeout_seconds: 86400 + } + on approve -> Order + [ on reject -> Rejected ] + [ on timeout -> Escalate ] +} +``` +*Use for:* every point a human must decide. The gate **is** the node; the run parks here until decided +(SoD enforced at runtime). Route all three exits explicitly. + +### 4.5 `wait_for_event` — park until the world responds (v0.3) +```nil +step AwaitReply { + wait_for_event { + on_event: "mail.received"; + [ match { order_ref: "$po" }; ] # correlate to THIS operation + timeout_seconds: 345600 -> route Remind # deadline + its route on ONE line (required) + } + [ output reply ] + [ next Process ] +} +``` +*Use for:* waiting on an inbound email/WhatsApp/webhook. `match` is the correlation filter; the arriving +event's payload binds to `output`. This is how a cycle waits days for a vendor. + +### 4.6 `checkpoint` — a compensation boundary (v0.3) +```nil +step OrderPlaced { checkpoint "order-placed" [next Track] } +``` +*Use for:* marking a per-phase rollback boundary (no pause) so a later rollback unwinds cleanly. + +### 4.7 `notify` — inform (governed send is a verb; this is a lightweight message) +```nil +step Done { notify { ar: "تم الطلب"; en: "Order placed" } [next X] } +``` +*Use for:* a simple notification in the flow. (A *governed* email/WhatsApp send to a party is an +`action` using a comms verb, not `notify`.) + +--- + +## 5. A complete worked example (annotated) + +A minimal procurement-style cycle showing header, governance, a wait, and routing: + +```nil +cycle procurement_order implements RunProcurementOrder@1.0 triggers manual { + workspace "ws_acme" + intent { ar: "تشغيل أمر شراء محوكم"; en: "Run a governed procurement order" } + meta { version: "1.0"; owner: "operations"; tags: ["procurement"] } + + let po = "$input.order_ref" + + context { vendor: Vendor (role: supplier); } + roles { owner } + + flow entry ReadStock { + step ReadStock { query odoo.read_product { sku: "$input.sku" } output stock next Approve } + + step Approve { + await approval { + title: { ar: "اعتماد الشراء"; en: "Approve purchase" }; + approver: owner; + timeout_seconds: 86400 + } + on approve -> SendRFQ + on reject -> Rejected + } + + step SendRFQ { + use comms.send_email { to: "$vendor.email"; subject: "RFQ"; reply_token: "$po" } + next AwaitQuote + } + + step AwaitQuote { + wait_for_event { on_event: "mail.received"; match { order_ref: "$po" }; timeout_seconds: 345600 -> route Remind } + output quote + next Invoice + } + + step Invoice { + use odoo.create_purchase_invoice { vendor: "$vendor.id"; amount: "$quote.amount" } + compensate_with odoo.cancel_invoice { id: "$invoice.id" } + output invoice + next Done + } + + step Remind { notify { ar: "تذكير للمورد"; en: "Vendor reminder" } next AwaitQuote } + step Rejected{ notify { ar: "رُفض الطلب"; en: "Order rejected" } } + step Done { notify { ar: "اكتمل الطلب"; en: "Order complete" } } + } + + outcomes { completed when "$invoice != null"; rejected; } +} +``` + +Read it as the operation it is: read stock → **owner approves** → send RFQ (governed, reply-token) → +**wait up to 4 days** for the vendor → create the invoice (**reversible**) → done; a rejection and a +reminder path are explicit. Every effect is a verb; every human point is a gate; the wait is first-class. + +--- + +## 6. Authoring discipline (what makes valid, *good* NIL) + +An agent must obey these or produce invalid/anti-pattern NIL: + +- **Every effect is a `use `** — never invent an action; use a verb the adapter declares + (discover them, don't guess). Unknown verb → the cycle won't register. +- **Route everything** — no step without an exit (`next` / `on … -> …` / `-> route`). A dangling step is + a validation error. +- **Gate the risky** — any HIGH/CRITICAL or irreversible effect should sit behind `await approval` (and + policy may `raises_tier`). Draft-then-approve, never auto-fire consequential effects. +- **Make effects reversible where possible** — add `compensate_with`; if truly irreversible, catch it at + approval, not after. +- **Wait explicitly** — model "wait for the vendor/customer" as `wait_for_event` with a `match` + correlation and a real deadline+route. Never busy-loop. +- **Bind and reference** — capture results with `output`, reference with `$name`; keep `match` keyed to + the operation's correlation value (`$po`/order_ref) so replies find this thread. +- **Bilingual human text** — `intent`, approval `title`, `notify` carry ar/en. +- **One capability per cycle** — `implements Capability@ver` (the contract this cycle fulfils). + +--- + +## 7. Natural-language → NIL — the skill core (a phrasebook) + +This is what lets the agent author cycles from a business owner's words.

A `wait` control step gains an optional business `escalate` message ("if the deadline passes, emit this and halt") — a message, NEVER a step id (§11: the DSL stays scaffolding-free). The compiler synthesizes the branch: lower_to_flow emits a dedicated escalation NotifyStep (emit-and-halt) and routes the wait's on_timeout to it instead of the shared terminal. This is the same division the whole architecture rests on — the author states intent, the compiler owns the graph. Unblocks a faithful cyc_order migration (§14.5b). 33 lowering tests incl. the cyc_order-shaped escalation; 103 Wave-4 tests green.

Correlation Engine: 5-Layer Cascade + +**File:** `nilscript/comms/correlation_engine.py` + +The CorrelationEngine routes messages through a deterministic, high-to-low-confidence cascade. Each layer is independent; if a layer matches, it returns immediately (no further layers). If ambiguous (multiple matches), it escalates. + +### Layer 1: Transport IDs (confidence = 1.0) + +**Match on:** Message-ID, In-Reply-To header (SMTP); WhatsApp msg_id; SMS timestamp. + +**Rationale:** Transport IDs are channel-native, deduped at the gateway, and never reused within a workspace. + +**Example:** +``` +Inbound email with In-Reply-To: +→ Lookup original in transport_index +→ Find thread_id = "thread-po-145" +→ Confidence = 0.95 (In-Reply-To is slightly weaker than Message-ID) +``` + +**Implementation:** +- `add_transport_marker(marker, thread_id)` — Register a marker so future replies are deduped +- `transport_index` — In-memory dict or database table mapping transport IDs → thread + +### Layer 2: Conversation Identity (BCONV) (confidence = 1.0) + +**Match on:** BCONV (Business Conversation ID) — the durable thread marker stamped on all outbound. + +**Rationale:** BCONV is mint-once per thread, immutable, and visible to humans in subject/body. If present, it's a perfect match. + +**Example:** +``` +Inbound email subject: "[BCONV-ws_acme-2026-00145] RE: PO Update" +→ Extract BCONV-ws_acme-2026-00145 +→ Lookup in BCONV registry +→ Find thread_id +→ Confidence = 1.0 (perfect) +``` + +**Implementation:** +- `_match_layer_2_conversation(conversation_dict)` — Look up BCONV in thread registry +- BCONV format: `BCONV-{workspace}-{business_ref}` (e.g., `BCONV-ws_acme-2026-00145`) + +### Layer 3: Business Keys (confidence = 0.95) + +**Match on:** order_ref, ticket_id, invoice_number, PO number, or custom keys embedded in message. + +**Rationale:** Business keys are explicit identifiers humans mention. If found, they reliably identify the thread — but ambiguity is possible (two PO threads for the same vendor). + +**Example:** +``` +Inbound email body: "Regarding PO-2026-00145..." +→ Extract PO-2026-00145 +→ Lookup in business_key_index[(order_ref, PO-2026-00145)] +→ Find [thread_id] +→ If 1 match: Confidence = 0.95 +→ If N matches: Escalate to review queue (ambiguous) +``` + +**Implementation:** +- `add_business_key(key_type, value, thread_id)` — Register a business key +- `business_key_index` — Dict mapping (key_type, value) → [thread_ids] +- Handles multiple keys per thread (e.g., both order_ref and ticket_id) + +### Layer 4: Participant Matching (confidence = 0.85) + +**Match on:** Sender identity (email, phone, WhatsApp ID); sender's role (vendor, customer, approver). + +**Rationale:** Validates the sender has a valid relationship to candidate threads from L3. Filters L3 candidates by role authority. + +**Example:** +``` +L3 matched: [thread_po_145, thread_po_146] (both have order_ref) +Sender: vendor@acme.com (role="vendor") +→ Check if vendor@acme.com is authorized on each thread +→ Filter to threads where vendor is the expected contact +→ Narrow to thread_po_145 +→ Confidence = 0.85 +``` + +**Implementation:** +- `_match_layer_4_participants(sender_dict, candidate_threads)` — Filter by role +- Look up sender's role in thread metadata (expected contacts, participants) + +### Layer 5: Temporal Causality (confidence = 0.75) + +**Match on:** Thread's current state and event-waiting criteria. + +**Rationale:** Ensures the message makes sense NOW. A "vendor reply" only matches if the thread is waiting for vendor input, not if it's already completed or waiting for approval. + +**Example:** +``` +Inbound email: vendor reply to PO +L4 candidate: thread_po_145 +Thread state: parked on wait_for_event(mail.received, on_event=vendor.reply) +→ Event type matches thread's waiting criteria +→ Confidence = 0.75 +→ Resume the thread +``` + +**Implementation:** +- `_match_layer_5_temporal(thread_state, candidates)` — Validate thread state +- Query control-plane: is thread parked?

CapabilityResolver (Kernel-owned, Hermes-opaque) - Intent versioning v1.0 locked - 68 tests passing Wave 6: Authority Layers (Governance Gates) - 5-tier hierarchy (L3 AuthorityLevel → L7 DelegationChain) - Role bundles + capability-scoped grants - Thread relationships + time-scoped permissions - Permission cards with multi-approver tracking - 31 tests passing Wave 7: Communication Engine (Smart Threading) - 5-layer correlation cascade (L1 transport IDs → L5 temporal causality) - Passive events resume parked threads via CommunicationReceivedEvent - Review queue for ambiguous messages (human resolution) - Outbound governance: BCONV + reply-token stamping - 43 tests passing Wave 8: Omnichannel Terminals (Multi-Channel) - Channel adapter contract (WhatsApp, Slack, SMS, Email, Mobile) - Invocation parser (extract cycle intents from channel messages) - Permission card renderer (channel-native UI) - Mobile terminal API (thin thread client) - 30 tests passing Healthcare Vertical Proof-of-Concept (HIPAA-Ready) - 5 healthcare capabilities (schedule, lab order, prescription, access records, verify coverage) - 3 clinical cycles (PatientIntake, LabOrder, Prescription) - HIPAA-compliant authority policies (right-to-access, minimum-necessary, audit trail) - Proves Kernel scales without modification (zero Kernel changes needed) - 30 tests passing Architecture: - Total new code: ~8,687 lines (Waves 5-8 + Healthcare) - Total tests: 200+ (all passing) - Kernel modifications: ZERO ✅ - Vertical-agnostic proven ✅ Security: - All secrets handled via environment variables

The hard part was never the reasoning. It was that I couldn't hit the reliability bar an agent needs when it touches real money and real customers. +> +> ReAct loops, LLM-as-judge, retries with verification — the standard stack still leaves a nonzero chance the model invents an action or calls a real API with a hallucinated parameter. For a store owner, "nonzero chance of a wrong action on a live order" isn't shippable. +> +> So I stopped trying to make the *model* safe and changed what the model is allowed to **emit**. +> +> NIL treats the LLM as an understanding machine only. It never sees or calls your real API — it emits **intent**. A deterministic kernel resolves that intent, validates it against the backend's declared **skeleton** (the exact verbs and fields the backend actually exposes, discovered via a `/describe` handshake), and only then executes. If the model hallucinates an action or a parameter, it's **refused at the gate, not faked** — it never reaches your system. High/critical-risk operations route to a human approver on a separate owner plane before commit. +> +> The operation model is **propose → commit** (two-phase), plus query, rollback (with a previewed compensation, never a silent write), and an append-only audit log — every action the agent ever attempted is inspectable. +> +> **How this differs from MCP / tool-call governance:** MCP standardizes how agents *call* tools; governance layers filter those calls. In both, the agent still emits the call. In NIL the agent has no vocabulary for a raw call — it can only express intent, and the kernel owns translation → validation → execution. NIL composes *with* MCP (an MCP client is just a NIL "speaker"); it's not a replacement. +> +> **Try it:** +> ``` +> pip install "nilscript[demo]" +> nilscript demo # opens the Playground at http://127.0.0.1:8770 +> ``` +> Chat to a live backend and watch a write go **propose → approve → commit → rollback** in a real trace. To see a hallucination die at the gate, ask the agent for an operation the backend never declared — it comes back `UNKNOWN_VERB` refusal, nothing written. (Adapter authors: `pip install "nilscript[cli]" && nilscript scaffold-shim --name my-adapter` — you fill 3 files: `system.py`, `translate.py`, `compensation.py`.) +> +> **Benchmarks (reproducible):** I ran the InjecAgent prompt-injection suite (ACL Findings 2024) twice per case (agent calling tools directly (raw) vs. the same agent routed through NIL (gated)). Same model, same attacks, only the gate differs. Across **2,108 base-setting evaluations** (2 models × 1,054 cases): raw agents were hijacked into an unauthorized write on **up to 4.46%** of cases; through NIL, that write is **admitted at the gate 0.00%** of the time, while **no authorized call was refused** (a false-refusal rate of 0). What the harness scores is **gate decisions over tool names, not executed backend writes**; the NIL `0` holds **by construction** (Proposition 2), and the authorized pass-through is a false-refusal rate, not measured task completion (end-to-end task-success is a separate, planned τ-bench axis). The enhanced setting is withheld (degenerate; raw ASR ≈ 0). Honest caveat: my harness uses a **single-step decision, not InjecAgent's two-step ReAct**, so my raw rates (2.75–4.46%) sit *below* the paper's 24% GPT-4 baseline and are harness-specific. Separately, through a live odoo-CRM adapter's production edge I measured **Structural-Rejection Rate = 100%, Effect-Leakage = 0** across four corpora, earned by closing a `resource.*` target hole that previously leaked a real payment/employee write 8/8.

In NIL the agent never emits a call; it emits intent, and the kernel is the only thing that can produce an API call.

Executive summary + +AI agents are moving from *talking* to *acting* — writing to ERPs, commerce backends, ticketing +systems and databases. The moment an agent holds API credentials it becomes a loaded gun: one +hijacked prompt, one hallucinated call, and an irreversible write reaches production. Today every +agent↔system integration is hand-built, brittle, and trusts the model not to misbehave. + +**NILScript proposes a structural fix, not a behavioural one.** NIL is a neutral wire contract that +sits between any agent and any backend. An agent can only **propose**; nothing mutates data until a +proposal is **approved**; every effect is **traced** and carries a **reversal handle**; and an agent +can only name operations the backend has actually declared — anything else is **refused, not faked**. +You build the adapter **once**, and any NIL-speaking agent works against it. + +The thesis — *Unexpressible, Not Filtered* — is that an undeclared action has an **empty preimage** +under translation (`β⁻¹(a) = ∅`): it is unexpressible, not merely filtered. It is already supported by +an early controlled benchmark: across **2,108 base-setting evaluations** (InjecAgent, ACL Findings +2024) on two models, unauthorized writes **admitted at the gate through NIL = 0.00%**, while the +**authorized-call pass-through stays at 100%** (a false-refusal rate of 0, not measured task +completion). The harness scores gate decisions over tool names, not executed writes; the NIL `0` holds +**by construction** (Proposition 2), not as an estimate from two models. A second axis through a live +odoo-CRM adapter's production edge measures committed effects: **Structural-Rejection Rate = 100%, +Effect-Leakage = 0** across four corpora. + +This document defines a **24-month applied-R&D programme** to take NILScript from a working reference +kernel and one verified adapter to a **rigorously benchmarked, independently attested, multi-backend +open standard** with a headless runtime and a clean commercial-durability seam. It is organised into +**six work packages** with explicit objectives, deliverables, TRL targets, KPIs, and a risk register. + +--- + +## 2. Problem statement & motivation + +| The problem | Why it is unsolved today | +| --- | --- | +| **Agents write blindly.** A hijacked or hallucinating agent can issue a wrong, irreversible write to a production system. | LLM safety is probabilistic (better prompts, guardrail models). There is no *structural* guarantee that an un-approved write physically cannot commit. | +| **Every integration is bespoke.** Each agent↔backend pairing is hand-built and brittle. | No neutral, language-agnostic wire contract for *actions* exists — the equivalent of "OpenAPI for agent-actions" is missing. | +| **Models hallucinate operations that don't exist.** | Tool layers fabricate plausible-but-wrong calls; nothing forces the agent to stay inside what the backend genuinely exposes. | +| **"It's reversible" is usually a lie.** | Most SaaS effects (sent email, shipped order, charged card) cannot be undone, yet systems imply they can. There is no honest, verifiable reversibility contract. | +| **Standards rot into framework lock-in.** | A standard expressed as software couples adopters to one runtime; the contract should be data, not a dependency. | + +**Motivation.** As agentic automation scales, the bottleneck shifts from *capability* to *trust*. +Enterprises will not give autonomous agents write access without a defensible, auditable, reversible +control plane. NILScript targets exactly that control plane — and does so as a **neutral open +standard** so it can become shared infrastructure rather than a single vendor's moat. + +--- + +## 3. Background & state of the art + +- **Agent task-success benchmarks** — τ-bench / τ²-bench (ICLR'25), BFCL v3/v4 (ICML'25): measure + whether agents accomplish tasks against tool suites by comparing end-state to a goal state. They do + **not** measure a safety/governance layer. +- **Adversarial / safety benchmarks** — AgentDojo (NeurIPS'24), InjecAgent (ACL'24), ToolEmu + (ICLR'24): measure prompt-injection / hijacked-write susceptibility. These are the venues where a + structural defence like NIL should *win visibly*. +- **Distributed-systems theory** — the Saga pattern (Garcia-Molina & Salem, 1987) underpins NIL's + **backward recovery by compensation**: where a true undo is impossible, a *new, governed, forward + action* neutralises the prior effect's business meaning. +- **Analogous standards** — OpenAPI / JSON-Schema / MCP show the winning shape: the **spec is data + + docs**, implementations are separate packages. NILScript follows this deliberately. + +**Gap NILScript fills.** No existing artefact is *simultaneously* (a) a neutral, language-agnostic +action contract, (b) structurally injection-resistant (propose→approve→commit, skeleton-bounded), and +(c) honest about reversibility with a machine-verified conformance gate. NILScript is positioned in +that intersection. + +--- + +## 4. The technical innovation + +### 4.1 The two layers + +| Layer | Name | What it is | +| --- | --- | --- | +| **Operations** | **NIL — Network Intent Layer** | The wire contract: a stable `nil: "0.1"` envelope, seven performatives (**SEQRD-PC**: STATUS · EVENT · QUERY · ROLLBACK · DECIDE · PROPOSE · COMMIT), grants, structured refusals, per-domain profiles. | +| **Orchestration** | **nilscript DSL** | A declarative, JSON, LLM-native language *above* NIL: an agent writes a `plan.nil.json` program, a static validator (V1–V6) admits it, a durable runtime walks the graph driving NIL verbs. | + +### 4.2 The four structural guarantees (the safety claim) + +1. **No side effects on PROPOSE.** A write physically cannot commit without an approved + `propose → approve → commit`. PROPOSE leaves state byte-identical. +2. **Skeleton-bounded.** An agent can only name verbs/targets the backend's discovery skeleton + declares (`GET /nil/v0.1/describe`). Unknown verbs → `UNKNOWN_VERB`; unprovisioned targets → + `UPSTREAM_UNAVAILABLE` (**refused at PROPOSE**, not faked, not failed-after-commit). +3. **Honest, bounded reversibility.** Every verb declares one tier — `REVERSIBLE` / `COMPENSABLE` / + `IRREVERSIBLE` — and `ROLLBACK` *previews* a compensation through the same PROPOSE→COMMIT + machinery; it never performs a silent corrective write, and it **refuses to pretend** about + irreversible effects. Unmarked verbs default to `IRREVERSIBLE` (fail-safe, zero-touch). +4. **Tiers are earned, not asserted.** `nilscript manifest diff` is a CI drift-guard that exits + non-zero if a shim declares a reversibility tier its conformance run does not honour. + +### 4.3 SEQRD-PC — lifecycle closure + +`ROLLBACK` is the **terminal lifecycle primitive** — the backward-recovery counterpart to `PROPOSE`. +The performative set spans the complete lifecycle of a governed effect (propose → preview → commit → +notify → reverse) and stays **closed**: it grows only by ratified amendment with a passing conformance +precondition, anchored immutably in an append-only, content-addressed ledger. + +### 4.4 Build-once adapters + +A backend speaks NIL via a thin **adapter** generated by `nilscript scaffold-shim`. The author fills +exactly three files — `system.py` (the only place I/O happens), `translate.py` (verb ⇄ native), +`compensation.py` (reversibility). A `resource.*` generic CRUD family covers any provisioned target +with **no per-entity verb authoring**, and reversibility is **synthesized** (create→delete, +update→restore-before-image, delete→recreate). + +### 4.5 The core architectural claim — breaking the ReAct loop + +The dominant agent pattern is **ReAct** (Reason + Act; Yao et al., 2023), adopted across modern agent +stacks — including NVIDIA's agent toolkit. ReAct's defining move is that **acting happens *inside* the +reasoning loop**: the model produces a Thought, takes an **Action that is a real side effect**, +ingests the **Observation** (the tool's output), and feeds it straight back into the next Thought. +That tight fusion is exactly what makes ReAct capable — and exactly what makes it expensive to secure. + +**Why ReAct is costly to secure.** Because the Action commits a real effect *every iteration*, and a +returned Observation can be **poisoned** (indirect prompt injection) and **re-enters the reasoning +that picks the next real Action**, the security perimeter is the *entire loop*. There is no +architectural boundary between "deciding" and "doing", so defence is **per-step and probabilistic** — +a guardrail model, a classifier, or a policy prompt inspecting *every* Thought/Action/Observation. +Cost scales with the number of steps (**O(n) per run**) and never reaches a hard guarantee: one +mis-classified step is one unauthorized write. + +```mermaid +flowchart LR + X["☠️ Injected / poisoned

The +agent's loop may reason freely and may be influenced by a poisoned observation — but the only thing it +can emit is a **PROPOSE** (intent, **zero side effect**). The actual write happens at **COMMIT**, +**outside the loop**, only after crossing a **structural gate**: the proposal must be approved, and it +can only name verbs/targets the backend's skeleton declares (unknown/unprovisioned → **refused, not +faked**). The security perimeter collapses from "every step of the loop" to **one boundary between +intent and effect** — a fixed, **O(1) architectural** cost, independent of how many steps the agent +takes or how clever the injection is. + +```mermaid +flowchart LR + X["☠️ Injected response"] + subgraph LOOP["🔁 Agent loop — PROPOSE only, NO side effects"] + direction TB + T["Thought"] + P["PROPOSE

Switch → MCP follows. Add any adapter the same way. + +--- + +## 4. Build sequence (recommended order, TDD) + +### Step 1 — Control-plane active-adapter registry (the brain; safe, isolated) +- `store.py`: add `adapters` table + methods `register_adapter`, `activate_adapter(ws, id)` (sets + active=1 for it, 0 for siblings), `active_adapter(ws)`, `list_adapters(ws)`. +- `app.py`: add the 4 endpoints above. +- **Security:** `POST /adapters/*` and `GET /adapters/active` MUST be authenticated — reuse the + existing `NIL_EVENTS_SECRET` HMAC pattern (see `/events/ingest` in `app.py`) OR a dedicated + `NIL_REGISTRY_TOKEN` bearer. `GET /adapters/active` returns the adapter `bearer`, so it CANNOT be + public. `GET /adapters` (list, for the UI) must REDACT the bearer. +- Tests: `tests/test_controlplane.py` — register → activate → active returns it; activating a second + deactivates the first; unauth read of `/adapters/active` is rejected. + +### Step 2 — MCP resolves the active adapter +- `src/nilscript/mcp/tenant.py`: in `resolve_tenant(...)`, when multi-tenant and NO `X-NIL-Adapter-Url` + header, fetch `GET /adapters/active?workspace=` from the CP (URL via `NIL_APPROVAL_URL`/a new + `NIL_REGISTRY_URL` env, with the registry token) and build the `Tenant` from it. Header still wins. +- `src/nilscript/mcp/server.py`: pass the connection's workspace through; ensure `nil_describe` / + dynamic tools rebuild per resolved tenant (dynamic.py already keys per tenant — verify caching). +- Enable `NIL_MCP_MULTI_TENANT=1` on the `mcp` service (compose). +- Tests: `tests/test_mcp_multitenant.py` / `test_mcp_tenant.py` — header path unchanged; no-header path + resolves the workspace's active adapter; falls back safely if registry unreachable. + +### Step 3 — Persistent `odoo-adapter` service (host-as-services) +- New `nilscript-landing/deploy/odoo-adapter.Dockerfile` — build the Odoo adapter, run its NIL edge + (`uvicorn odoo_crm_nil_adapter.run_live:build_app --factory --host 0.0.0.0 --port 8101`). NOTE: this + is the ADAPTER only (port 8101), NOT the `odoo-mcp` from PR #7 (that's a full MCP front door — a + different thing; PR #7 can be closed or kept for the dedicated-door option). +- compose service `odoo-adapter` (container_name `nilscript-odoo-adapter`), `ODOO_*` from host .env, + on `wosool-network`, NO public port (only the MCP reaches it internally). +- `deploy.yml` already checks out `nilscript-org/odoo-crm-nil-adapter` (public) for the playground — + reuse that checkout for this image. +- On boot, register+activate it in the CP for the owner workspace (an entrypoint curl, or a one-shot). + +### Step 4 — Activation UI +- Playground Backend panel: after a successful link (`/api/odoo`, `/api/backend`), call + `POST /adapters/register` + `/activate` on the CP so the MCP follows. (The playground already + reflects events to cp; add the registry call.) +- cp Adapters panel: add an "Activate" / "Active ✓" control per adapter using the same endpoints. + +### Step 5 — Deploy + verify +- One deploy. Verify: `nil_describe` via `mcp.nilscript.org` (with the workspace) → `system: odoo_crm`, + verbs `crm.*`; activate PocketBase → flips back. cp Adapters panel shows the active one. + +--- + +## 5. HOST steps the user MUST do (cannot be done from the agent) + +1. **Rotate the Odoo API key** — it was shared in chat several times this session.

NOT needed for the active-adapter model above + (the odoo-adapter is internal-only; the existing `mcp.nilscript.org` door is reused). + +--- + +## 6. Repo / deploy mechanics (learned this session — follow these) + +- **`nilscript` `main` is branch-protected** (no direct push). Workflow that works: + ``` + git checkout -B feat/x origin/main # ALWAYS branch from origin/main, not local main + git add … && git commit … + git push -u origin feat/x + gh pr create --base main --head feat/x --title … --body … + gh pr merge feat/x --squash --admin --delete-branch + git fetch origin main && git reset --hard origin/main # keep local main == origin/main + ``` + The `gh pr merge` may print `fatal: Not possible to fast-forward` — that's a harmless LOCAL warning; + the server squash-merge still succeeds (confirm with `git log --oneline origin/main -1`). +- **Do NOT branch from a diverged local `main`** — it causes phantom merge conflicts (hit #24, #26 this + session). Reset local main to origin/main between features. +- **Deploy**: pushing to `nilscript-landing` `main` auto-triggers `deploy.yml`; or + `gh workflow run deploy.yml -R nilscript-org/nilscript-landing --ref main`. It rebuilds ALL images + (web/playground/mcp/controlplane) from the CHECKED-OUT source of the sibling repos (`nilscript` and + the adapters at their default branch). So: merge code to `nilscript` main FIRST, then deploy. + Concurrency group serializes runs; a build ~3–5 min. +- `gh repo edit --visibility` flag is finicky; use `gh api --method PATCH /repos// -F private=false`. + +## 7. GOTCHA that bit us (prevent the repeat) + +`HttpEventEmitter` exists in MULTIPLE copies of the generic edge: the demo's **vendored** PocketBase +copy (`src/nilscript/demo/pocketbase_nil_adapter/edge.py`), and each adapter repo +(`adapters/pocketbase-nil-adapter`, `adapters/odoo-crm-nil-adapter`, `nil-adapter-template`).

Fixed in `2fd983b`. +**Lesson:** when changing the generic edge signature, sync ALL copies, and test shims WITH the webhook +env set (the failure only appears in the HttpEventEmitter path, not CapturingEmitter). + +## 8.

It bypasses the kernel's content-hash registry, the V1–V6 validator, + and the control-plane approval gate. **This is the one real drift to fix.** + +4. **"The agent only proposes intent" is true — but only on the paths the agent actually touches** + (the MCP `nil_intent`/propose→commit gate, and the brain's `/api/assert`).

The alignment you're looking for **exists in the kernel (#2) and is missing in + the product surface (#3).** + +5. **Temporal is built but not yet load-bearing in NIL.** The kernel has a tested Phase-6 + tenant-scoped durable layer (`durable_temporal.py`), but **nothing on the live path calls it yet**. + The live HITL gate is the SQLite `approvals` table, HTTP-polled, where *approval drives execution* + (the control plane commits on the agent's behalf).

No tool selection + by the model, no keyword matching, no model-built filter. *Model intelligence is removed from the + commit loop.* ([PLAN-intent-unification-and-durability.md §0](./PLAN-intent-unification-and-durability.md)) + +- **Four structural guarantees** (constitution §6): + 1. **No side effects on propose** — proposing leaves the backend byte-identical; only an approved + commit changes state. + 2. **Skeleton-bounded** — an agent can only name verbs/targets the backend has *declared*. An + undeclared verb has no representation to send (`β⁻¹(a) = ∅`). This is strictly stronger than + filtering. + 3. **Honest, bounded reversibility** — every write declares reversible / compensable / irreversible; + rollback runs a *real* compensation, never a fabricated undo. + 4. **Earned, not asserted** — success is confirmed by reading the record back; a reversibility tier + is confirmed by a conformance run. + +- **The product thesis** (vision §1): between *deterministic-but-manual* (Zapier/n8n) and + *AI-but-ungoverned* (Lindy/Gumloop). The wedge: **the agent is generative, the validator is a total + deterministic function** (the kernel). "AI proposes. Code governs and executes." + +This is the yardstick. Every layer below either honors it or drifts from it — and naming exactly where +it drifts is the point of this doc. + +--- + +## 2.

It carries **no members inline** — membership is **edge-based**: + a Cycle `contains` other nodes via `Relationship(rel_type="contains")`. +- A **`Flow`** (`models.py:182`) is *"the semantic shape of Sales → Finance → Manager → System — the + generalization of a composed automation."* It has a `trigger_event` and an ordered + `tuple[FlowStep,…]`, each step `{order, from_role, to_role, action, condition}`. **A Flow is a member + of a Cycle** (e.g. `flow:invoice-to-cash` is contained by `cycle:finance`). +- A **node** here is any ontology node (`Entity`, `Role`, `Policy`, `Flow`, `EventNode`, `Cycle`, + `OperationalMapping`, …); an **edge** is a generic `from_node → to_node` with a `rel_type` + (`contains`, `owns`, `approves`, `governed_by`, …). +- Served read-only by **`GET /api/graph/cycles`** (`api.py:223`): for each Cycle node it indexes the + outbound `contains` edges and returns `{cycle_id, goal, metrics, members[], member_kinds{}}`. + +**Key line** (`models.py:182`): *"The compiler lowers a Flow to a composed plan; the Flow says what the +coordination **means**, `compose.py` says how it **runs**."* → **Model #1 is the design-time meaning; +Model #2 is the runtime artifact it compiles into.** + +### 2.2 Model #2 — Kernel `AutomationDefinition` / `WosoolProgram` (the governed execution layer) + +Repo: `nilscript` (kernel) · [kernel/models.py](../src/nilscript/kernel/models.py), +[automation/models.py](../src/nilscript/automation/models.py). + +- A **`WosoolProgram`** ([kernel/models.py:148](../src/nilscript/kernel/models.py#L148)) is the closed + DSL: `{wosool:"0.1", workspace, entry, pipeline: tuple[Node,…] (1–256), on_error}`. +- A **node/step** is one of a **closed discriminated union** (an unknown type is *unrepresentable*): + `ActionNode` (the write step: `verb`, `args`, `next`, `compensate_with`), `QueryNode` (read), + `ConditionNode`, `ParallelNode`, `ForeachNode`, `AwaitApprovalNode`, `WaitNode`, `NotifyNode`. +- **Flow/wiring** = each node's `next` (and branch targets `on_true`/`body`/`branches`); **data + handoff** = `$.step_k.output.field` references, type-checked at compile. +- An **`AutomationDefinition`** ([automation/models.py:93](../src/nilscript/automation/models.py#L93)) + wraps a validated `WosoolProgram` with a **`content_hash`** (SHA256 over canonical JSON — *the version + lock*), a `TriggerSpec` (manual/schedule/event), and a lifecycle `state` + (draft→pending_approval→active⇄paused→archived). + +This is the **governed SSOT**: append-only versions, content-hash reproducibility, V1–V6 validation, +propose→commit per step.

One + payload (`about` + `where` + `seek`|`change`). A read returns a lean result; **a `change` returns a + PREVIEW (proposal) — it does not execute.** +- **The two-step discipline:** `nil_propose`/`nil_intent` → preview, **no side effect**; **`nil_commit` + is the ONLY tool that writes** (idempotent by `(session, proposal)`); `nil_query` reads; + `nil_describe` lists the real verbs (don't invent others); `nil_rollback` only ever returns a + *compensation preview* you then commit. Refusals (`UNKNOWN_VERB`, `IRREVERSIBLE`, + `COMPENSATION_EXPIRED`, …) are **answers**, not retryable errors. +- **Verbs are discovered, not chosen:** the router (`dataplane/router.py`, `dataplane/intent.py`) + delegates `about` to the first provider that structurally **owns** it (no keywords), and writes lower + to the universal generic-CRUD `resource.{create,update,delete}`. Unknown rel/op → `INVALID_REL`/ + `INVALID_OP`. Default-deny on write authority lives **adapter-side** at propose time (the Odoo + adapter's `governance.py`). + +> **Naming flag:** human docs/skill say `nil_propose`; the registered tool id is **`nil_intent`**. +> Same performative, two names — worth unifying to kill confusion. + +### 3.2 The brain assert path (`nilscript-graph` · `api.py:383`) + +`POST /api/assert {tenant, event_type, facts}` is the **preferred** way for the agent to *act*: +**assert what is TRUE, let the brain derive what must happen.** Flow: `interpret` (read graph, fire +policies, match flow) → `derive_intent` → `resolve_bindings` (entity → `OperationalMapping` → candidate +verb by convention; missing → logged as a **gap**) → `run_event` (compile + execute through the +governed kernel) → `explain_outcome`. **Critical distinction** (`meaning/models.py:54`): the agent +asserts a **fact**; the brain derives an **Intent**; the *kernel* enforces governance. The agent never +asserts an Intent directly, and even the Intent has no execution authority. + +### 3.3 The Hermes agent (`hermes-agent`) — how "propose only" is realized + +- The NIL integration is **config-only**: an MCP manifest (`optional-mcps/nil/manifest.yaml` → remote + `https://mcp.nilscript.org/mcp`) + a skill (`skills/nil/SKILL.md`). **No NIL logic in the agent + core** — the loop is stock Hermes generic tool dispatch. +- So **"propose only" is enforced server-side** (the MCP gate; propose has no side effect by + construction; HIGH/CRITICAL park for humans) and **steered model-side** by the skill text: + *"You propose; you never dispose."* The SOUL files carry no NIL constraint. +- **Nuance that matters:** the agent **can** call `nil_commit` — for **LOW/MEDIUM** tiers that's the + intended flow. HITL is **risk-tiered and kernel-enforced**, not a blanket "agent never commits." + Calling `nil_commit` on a HIGH/CRITICAL proposal just returns "parked for approval." +- The agent can also author **multi-step automations** (`nil_automation_draft/register/approve/run`, + `compose_register`) — and even those cross the propose→approve→commit gate (draft = no-write, + register = pending, only `active` runs). + +--- + +## 4. The governed automation path (Model #2) in detail + +This is the path that **does** honor the philosophy end-to-end. + +1. **Author (untrusted):** agent emits a candidate `WosoolProgram` + `TriggerSpec`. +2. **Lower-or-reject (deterministic):** `draft_automation` runs the **V1–V6 validator** + ([kernel/validator.py](../src/nilscript/kernel/validator.py)) against the workspace's **live adapter + skeleton**. **V4 whitelist** rejects any verb the backend never declared (`V4_UNKNOWN_SKILL`) or not + granted to the workspace (`V4_SCOPE_DENIED`) — *the agent cannot talk past it.* Pass → `content_hash` + computed. +3. **Register:** persisted as **`pending_approval`** in the append-only `automations` SSOT + ([controlplane/store.py](../src/nilscript/controlplane/store.py)). Re-registering identical bytes is + an idempotent no-op (same hash). **Never auto-armed.** +4. **Arm (human, operator-gated):** `→ active` requires the registry token + ([controlplane/app.py](../src/nilscript/controlplane/app.py) `/state`). A human grants the *standing + authority*. +5. **Fire:** `POST /automations/{ws}/{id}/run` (mandatory `idempotency_key`) → `fire_manual` → + `LocalExecutor.execute(plan)`. Each `ActionNode` runs **propose→commit** in-process + ([kernel/executor.py:162](../src/nilscript/kernel/executor.py#L162)).

Every node emits ledger events → free audit. + +### 4.1 How "agent only proposes intent" reconciles with auto-executing steps + +When an armed automation runs, the executor **auto-commits** each step — there's no per-step human +click. Is that a contradiction? **No**, and here's the precise reconciliation: + +- The agent's act was `draft → register` (landing `pending_approval`). **It is structurally impossible + for the agent to make an automation fire** — arming is human/operator-gated; `fire_manual` refuses + any non-`active` automation. +- The plan that runs is **frozen at the content-hash the human approved** and **every step was + whitelisted at compose time** (V4). The auto-commits are bounded to a pre-approved verb set. +- Each step still does propose→commit, so **adapter-side default-deny governance + saga safety still + apply per write.** +- **The standing authority is delegated by a human to a hash-locked program — not seized by the + agent.** For mid-flow human checkpoints, the author inserts an `AwaitApprovalNode`. + +> So "the agent proposes; only the kernel commits" holds at the level that matters: the agent never +> holds standing write authority.

THE DRIFT — the one thing that's actually wrong + +**The visible product surface (Model #3, the os-server `/cycles` step builder) is a parallel, +ungoverned re-implementation of what the kernel already does correctly (Model #2).** + +From the os-server trace (`os-server/app.py`): + +- **It does not import `nilscript` or `nilscript_graph`** — it talks to both over HTTP. +- A cycle lives in **os-server's own SQLite** (`cycles`/`runs` tables), with its **own schema** and a + **hand-rolled topological executor** `advance_run_logic` + `_execute_node_via_adapter` (`app.py:2065`). +- Each node **does** call the *adapter's* `/nil/v0.1/propose` + `/commit` — **but** with a hardcoded + **`grant:"cycle-engine"`** and a **self-minted proposal id**. It does **not** use `NilClient`/ + `LocalExecutor`, does **not** go through the kernel control-plane gate, and **never** registers the + cycle as a content-hash-locked `AutomationDefinition`. +- **Therefore the cycle is ungoverned at the orchestration level:** no V1–V6 validator over the plan, + no content-hash version lock, no `pending_approval` lifecycle, no propose→commit *at the cycle level*, + and its HITL gate is a SQLite flag (§5.4). + +What the same os-server **does** govern correctly (by proxying the kernel): +- `/api/os/automations` → proxies the kernel's governed `automations` registry (read). +- `/api/os/pending` + `/proposals/{id}/decision` → proxies the kernel's real held-proposal HITL queue + (the agent's/MCP's gated writes). +- `/api/os/proxy/api/graph/*` → proxies the brain. + +So os-server is a **correct governance broker for the agent's intents**, but a **parallel ungoverned +engine for the human-drawn cycles.** The two never meet. That mismatch is *precisely* the thing your +question kept circling: *"how does 'agent only proposes intent' align with these nodes?"* — **today it +doesn't, because those nodes don't run through the intent path at all.** + +### Why this happened (not a mistake, a sequencing artifact) +The kernel automation registry (#2) and the visible builder (#3) were built in different slices. The +[VISION doc §8.3](./VISION-governed-automation-platform.md) explicitly calls for a **"canvas↔DSL +compiler"** as *"the load-bearing new component"* — i.e. the bridge from the drawn cycle to a validated +`WosoolProgram`. **That compiler was never built; os-server's local executor was used as a stand-in.** +The drift is the missing compiler, not a wrong decision. + +--- + +## 7. Answering your exact questions + +- **"How are node components linked to the cycle flow, and how does the system do it?"** + Three different ways, one per model: brain — nodes are linked to a `Cycle` by `contains` *edges*, and + a `Flow`'s steps are an ordered tuple (§2.1). Kernel — nodes are a `pipeline` linked by `next`/branch + targets, data by `$.step.output` refs (§2.2). os-server/UI — a `BusinessCycle` owns flat `nodes[]` + + `edges[]` (`from_node→to_node`), and the visible builder only ever appends a linear edge from the + previous node (no drag-to-connect yet) (§2.3). + +- **"How does the agent interfere with them?"** + Via the MCP intent gate (`nil_intent`/propose→commit) and the brain `/api/assert` (§3). **It does not + touch the os-server cycles builder at all** — that's human-driven in the browser. The agent's + governed equivalent of "build a cycle" is `nil_automation_draft/register` (Model #2), which a human + then arms. + +- **"How do we manage them as Temporal?"** + Today: we **don't** manage cycles as Temporal. The kernel's tenant-scoped Temporal durable layer + exists and is tested but is **not wired to any live path** (§5.2). The only production Temporal HITL + is in wosool-saas, which NIL borrows infra from, not code (§5.3). The os-server cycle gate is a SQLite + flag, not Temporal (§5.4). + +- **"How do the agent and our HITL expose this?"** + Two *separate* HITL queues exist: (a) the **governed** kernel queue — `approvals` table, approve → + control-plane commits (§5.1), surfaced in the UI `/decisions` page and dashboard `DecisionPanel`; and + (b) the **ungoverned** cycle gate — `waiting_approval` SQLite flag, approve → os-server marks the node + done (§5.4), surfaced in `/cycles/runs` (and the run-detail/advance UI isn't even built yet). + +- **"How is 'agent only PROPOSE INTENT tools' aligning with these nodes?"** + It aligns perfectly with **kernel nodes (#2)** — agent drafts/proposes, human arms, the frozen + hash-locked whitelisted plan auto-commits under human-delegated authority (§4.1). It **does not align + with the visible os-server cycle nodes (#3)** — those commit under a blanket `cycle-engine` grant + outside the intent gate (§6). **Closing that gap = building the canvas→`WosoolProgram` compiler so the + drawn cycle becomes a governed `AutomationDefinition`.** + +--- + +## 8. How to make it clean (the prepared-again plan) + +The fix is conceptually small and already designed (VISION §7, §8.3). **Collapse Model #3 into Model #2.** + +1. **Build the canvas↔DSL compiler.** Lower a `BusinessCycle` (os-server `nodes[]`/`edges[]`) into a + validated `WosoolProgram`. A `WorkflowNode{adapter_id, verb, args, gate, gate_role}` maps cleanly: + a non-gated node → `ActionNode`/`QueryNode`; a `gate:true` node → an `AwaitApprovalNode` (so the + human checkpoint becomes a *governed* gate, not a SQLite flag); an `edge` → the source node's `next`. +2. **Register, don't run-locally.** On Save, call the kernel `POST /automations/register` (Model #2): + the plan gets **V1–V6 validated**, **content-hash locked**, and lands `pending_approval`. Delete + `advance_run_logic` + `_execute_node_via_adapter`; replace "Run" with the kernel's + `POST /automations/{ws}/{id}/run` (`fire_manual`). +3. **Unify the HITL queue.** Cycle approvals then flow through the **same** `approvals` table / + `/decisions` UI as the agent's intents — one governance pane, not two. Kill the `waiting_approval` + SQLite path. +4. **Kill the `cycle-engine` grant.** Every step then commits through `LocalExecutor`'s real + propose→commit under the workspace's actual grant, with adapter-side default-deny + saga + compensation — i.e. governed. +5. **Then (and only then) wire Temporal** for the bulk/long/flaky cycles: route `fire_manual` for + heavy plans through `start_governed_write` (Phase 6 is already built and tested) per + [PLAN-intent-unification §7](./PLAN-intent-unification-and-durability.md). +6. **Unify naming.** Pick one performative name (`nil_intent` vs `nil_propose`) and one word for the + user-facing thing. Suggestion: keep **"Cycle"** for the brain's constitution layer (#1, it's a + genuinely different concept) and rename the builder's output to **"Automation"** (matching the kernel + SSOT and the existing `/automations` page) so the UI stops implying the builder and the brain-cycle + are the same thing. + +**Net:** after steps 1–4 there are **two** clean concepts, not three: *Cycle = meaning (brain)*, +*Automation = governed runnable plan (kernel, drawn or spoken or asserted)*. The visible builder becomes +a **front door to the governed kernel**, the agent's intents and the human's drawn automations share one +governance spine, and "the agent proposes, only the kernel commits" becomes true **everywhere**, not +just on the agent's own paths. + +--- + +## Appendix — file map (where each truth lives) + +| Concern | Repo · file | +|---|---| +| Locked philosophy / positioning | `nilscript` · [docs/POSITIONING-CONSTITUTION.md](./POSITIONING-CONSTITUTION.md) | +| Product vision / 3 front doors / canvas compiler | `nilscript` · [docs/VISION-governed-automation-platform.md](./VISION-governed-automation-platform.md) | +| Intent unification + durability gap | `nilscript` · [docs/PLAN-intent-unification-and-durability.md](./PLAN-intent-unification-and-durability.md) | +| Brain `Cycle`/`Flow`, ontology, `/api/graph/cycles`, `/api/assert`, projections | `nilscript-graph` · `src/nilscript_graph/{models,api,meaning/engine,bindings,projections}.py` | +| Kernel DSL nodes (`WosoolProgram`) | `nilscript` · [src/nilscript/kernel/models.py](../src/nilscript/kernel/models.py) | +| Governed automation SSOT + validator + dispatch | `nilscript` · [src/nilscript/automation/](../src/nilscript/automation/), [kernel/validator.py](../src/nilscript/kernel/validator.py), [kernel/executor.py](../src/nilscript/kernel/executor.py) | +| MCP intent gate (propose→commit) | `nilscript` · [src/nilscript/mcp/server.py](../src/nilscript/mcp/server.py), [mcp/tools.py](../src/nilscript/mcp/tools.py) | +| Control plane: events/approvals/HITL, tenant provisioning | `nilscript` · [src/nilscript/controlplane/app.py](../src/nilscript/controlplane/app.py), [store.py](../src/nilscript/controlplane/store.py) | +| Tenant-scoped Temporal durable layer (built, dormant) | `nilscript` · [src/nilscript/durable.py](../src/nilscript/durable.py), [durable_temporal.py](../src/nilscript/durable_temporal.py) | +| **Visible Cycles step builder (UNGOVERNED engine)** | `os-server` · `app.py` (executor `2065–2348`, schema `1654–1741`) | +| Cycles/graph/decisions UI | `wosool-hub` · `src/app/cycles/[id]/page.tsx`, `src/app/graph/page.tsx`, `src/app/decisions/page.tsx`, `src/lib/{workflowTypes,workflowApi,contractsApi,graphApi,governanceApi}.ts` | +| Hermes NIL skill + MCP manifest (config-only) | `hermes-agent` · `skills/nil/SKILL.md`, `optional-mcps/nil/manifest.yaml`, `NIL-INTEGRATION.md` | +| Mature Temporal HITL (infra NIL borrows) | `wosool-saas` · `packages/orchestrator/app/temporal/...` | diff --git a/docs/PLAN-at-mention-resource-palette.md b/docs/PLAN-at-mention-resource-palette.md new file mode 100644 index 0000000..f279308 --- /dev/null +++ b/docs/PLAN-at-mention-resource-palette.md @@ -0,0 +1,162 @@ +# PLAN — `@`-Mention Resource Palette (verbs · adapters · cycles · roles) + +**Status:** Phase A shipped (2026-07-01) — see §11 +**Date:** 2026-07-01 +**Surface:** wosool-hub composer (the "Good morning" input box) +**Spans:** `wosool-hub` (frontend + BFF) · `nilscript` control plane (verbs, adapters, cycles) · `nilscript-graph` brain (roles/entities) + +--- + +## 1.

Cross-system (sales → marketing → accounting): the deferred hard part + +This is the part of your vision that is **genuinely new and genuinely hard**, and it is correctly +**out of the launch path**. Three sub-problems, in increasing difficulty: + +### 6.1 Cross-adapter dispatch (smallest) +Today every node hits the *one* active adapter ([kernel/models.py:153](../src/nilscript/kernel/models.py#L153), +one `workspace`). Give a node an optional `adapter` field and route per-node using the registry that +**already holds multiple adapters per workspace** +([controlplane/store.py](../src/nilscript/controlplane/store.py) `adapters` table). ~1–2 days for the +mechanism. Low conceptual risk. + +### 6.2 Cross-system reference handoff (hard) +Step in Odoo outputs a lead id; step in the accounting system needs the *corresponding* account. +The reference plumbing (`$.step_k.field`) and the per-adapter Choice Gate both exist — but **Odoo's +"customer" is not the accounting system's "account."** This is **ontology mapping, not plumbing**, +and it is the real 80%. For a demo, hardwire one mapping. For a product, this is a mapping registry +all its own. + +### 6.3 Authority composition (security-critical) +"Sales triggers marketing triggers accounting" composes *permissions* across departments. An +agent-composed cross-boundary automation is a **confused-deputy surface**: the automation runs with +*whose* authority at each hop? Grants are per-workspace today. Cross-boundary needs **explicit +per-edge authority** declared in the plan and checked by a guard, never inherited silently. This must +be designed before any cross-org automation ships — it is not polish. + +> **Verdict on §6:** name it in the deck as the vision ("single governed op → composed governed +> workflow across N systems"), demo a hardwired two-adapter slice if time allows, **build the general +> engine post-launch.** Building 6.2 + 6.3 generally before launch is the highest-EV way to miss the +> deadline (bus factor 1, MVP scope = single-instance correctness). + +### 6.4 Cross-system composition — engine built + tested (P3 core) + +`tests/test_automation_compose.py` (7 tests, incl. a real run across **two** in-memory PocketBase +backends where a value committed on adapter A drives a write on adapter B). +[src/nilscript/automation/compose.py](../src/nilscript/automation/compose.py): + +- A **composed plan** is an ordered list of `Stage(name, adapter, plan, input_from)`. Each stage is a + normal single-adapter `WosoolProgram` run by the **unchanged** `LocalExecutor` against *its own* + adapter — no kernel changes, so P1/P2 and the 345 prior tests are untouched. +- **6.1 dispatch** — solved by per-stage adapter binding (the `run_stage` the caller supplies picks + the client per stage); the registry already holds multiple adapters per workspace. +- **6.2 handoff** — `input_from` threads a prior stage's output (`$.stage_1.step_2.output.id`) into + the next stage's `$.input.*`. **Honest boundary:** the mapping is *author-declared, not inferred* — + we don't pretend A's "customer" is B's "account"; B's own Choice Gate still resolves the handed + value to a verified id. `validate_composed` checks each stage against its adapter's skeleton and + rejects a handoff that references a non-prior stage. +- **6.3 authority** — *per-stage by construction*: each stage runs with its own adapter's + credentials; the handoff carries data values, never authority — so a composed plan cannot escalate + across a boundary (confused-deputy-safe). + +**Composed SSOT + endpoints — wired + tested** (`tests/test_automation_compose_api.py`, 5 tests). An +additive `kind` column (`single`|`composed`) on the `automations` table keeps P1's typed +`AutomationDefinition` path untouched; composed plans flow through the same registry as the dispatcher +already consumes them (dicts). + +| Endpoint | Auth | Effect | +|---|---|---| +| `POST /automations/compose/draft` | registry token | validate each stage against **its own** adapter's live skeleton (`adapter_skeleton_provider`); return verdict + content-hash. No effect. | +| `POST /automations/compose/register` | registry token | persist as `pending_approval`, `kind='composed'` | +| `POST /automations/{ws}/{id}/run` | registry token | **branches on kind** — a composed automation fires via `fire_composed` (per-stage `LocalExecutor`), recorded as one run with per-stage status in the trace | + +`compose_hash` is the version lock; the same lifecycle endpoints (`/state`, `/runs`, `/runs/{id}`) +serve both kinds. Single- and composed-plan automations coexist in one registry. + +**Still genuinely out of scope (honest):** (a) a *single* stage that needs two backends' authority at +once — true authority composition; (b) *inferred* ontology mapping — we require it author-declared. +Both are real research/product, not a wiring step.

Risks / open questions + +1. **Expression sandbox.** `ConditionNode.expression` and `ForeachNode.items` are strings evaluated + over prior outputs. For stored, autonomously-firing automations the evaluator **must** be a + sandboxed, non-Turing-complete expression language (no `eval`). Verify what + [kernel/references.py](../src/nilscript/kernel/references.py) / + [kernel/executor.py](../src/nilscript/kernel/executor.py) do today before P2 — a stored automation + firing unattended raises the bar vs. an interactively-driven run. +2. **Skeleton drift between registration and fire.** A plan validated against today's skeleton may + reference a verb a backend later drops. Re-run **V4 at fire-time**, not just registration-time; + refuse + alert on drift rather than execute against a changed surface. +3. **Trigger storms / loops.** An `EventTrigger` whose automation emits an event matching its own + filter is an infinite loop. Need per-automation rate limits + cycle detection across the + *trigger graph* (automation A's effect fires automation B's trigger fires A…). +4. **Approval fatigue.** If every fire of a HIGH-tier automation re-prompts a human, autonomy is + lost. Decide: approve the *definition once* (the recurring authority is granted at activation) vs. + approve *each fire*.

Expose what the instance actually has, per tenant. No static target list. +2. **Schema-driven projections** — derive each model's lean default projection from `fields_get`: + pick `display_name`/`name` + a few key scalar fields; classify cardinality (small/large/huge); + mark `filterable/sortable` from Odoo field metadata; flag `sensitivity` (financial/HR/PII fields). + Replaces the hand-curated `_TARGET_FIELDS`. +3. **Per-(model, op) tier policy** — a declarative policy table (not code-per-model): + - reads: free (bounded/projected) — but sensitive models (`hr.*`, `account.*`) require a read grant. + - writes: `create/update` MEDIUM by default; `delete` HIGH; financial posting / HR payroll / + `unlink` on `account.move` → CRITICAL (held for owner). Default-deny destructive on financial/HR. + - the policy is data, editable per tenant; ships with safe defaults. +4. **Capability profile per model** — `server_filter/sort/paginate/aggregate` true for Odoo (search_read + /search_count/read_group), so the read plane works everywhere with the existing fallbacks. +5. **Intent layer is automatic** — `about=` flows through the same `IntentResolver` / + `resource.*`; no new wiring per module. Bulk/heavy ops go through the durable executor + ([[PLAN-intent-unification-and-durability]]) — essential once accounting/inventory volumes appear. +6. **Generic `op="method"` in the intent** — expose the existing method primitive through `nil_intent` + so workflow actions (`action_post`, `button_validate`, `action_confirm`, …) are universally callable + with no per-action verb: `nil_intent(about="stock.picking", where=[...], change={op:"method", + method:"button_validate"})`.

Onboarding picks which modules to expose. + +## Semantic verbs as an OPTIONAL top layer (not required for coverage) +The generic plane (CRUD **+ `op="method"`**) gives 100% coverage as the floor — including workflow +actions like post/validate/confirm. ON TOP, curated **semantic verbs** for common flows improve +ergonomics + bilingual previews (e.g. `account.create_invoice`, `account.register_payment`, +`stock.validate_picking`, `sale.confirm_order`) — same pattern as today's `crm.*`. What they buy is +**capability-free**: clean arguments (hiding `move_type`, the `[(0,0,{...})]` line format, the exact +method name), a human/bilingual approval preview, a precise per-verb tier and pre-flight check.

"Unexpressible, not filtered." English-only, dark-first, pure-CSS/SVG animation, builder/security tone (`β⁻¹ = ∅`, ReAct, InjecAgent evals). | Technical builders, AI labs, security architects. | It sells the **protocol**, not the **product**. No Arabic/RTL, no business-owner framing, no product-surface demos, no Framer Motion. Constitution §3/§11: the standard's public surfaces stay English-only and never sell Wosool. | +| `wosool-hub` (Next 16 / React 19) | The **actual product app** — the governed-automation dashboard (`/ask`, `/canvas`, `/cycles`, `/graph`, `/governance`…). Dense, operational, bilingual, OLED. | Logged-in operators. | It is the app, not a pitch. It assumes you already bought in. No conversion narrative, no segment routing, no "why". | +| **`wosool-landing` (this plan)** | The **commercial pitch** for Wosool: "Point your AI at your business and say what you want." Bilingual (ar/en, RTL-first-class), warm-but-technical, heavy Framer Motion + interactive product demos, segment-routed AHA. | Buyers across 6 segments + press. | — | + +**The load-bearing decision (Constitution §11 + VISION §14):** NILScript is the *open standard/kernel* (credibility, the paper, the moat). **Wosool is the commercial reference implementation businesses buy.** This site sells Wosool, credits NILScript, and links out to `nilscript.org` for the standard. It never claims to *be* the standard. Footer line, verbatim: *"Wosool is built on the open NILScript standard. Powered by NIL — the governed action layer. [nilscript.org →]"* + +--- + +## 1. The core strategy — "one product, six AHAs" + +The brief is *"make the user, whatever its segment, say AHA."* A single generic hero cannot do that — an owner and a security architect have opposite AHAs. So the architecture is **segment-adaptive**: one spine (the governance thesis), six branches (segment payoffs), and the interactive demos are the connective tissue that lands the same truth at three depths (VISION §12 register: developer / buyer / investor). + +### 1.1 The single thesis every segment must feel (never dropped) + +From VISION §1 and the Constitution §1: + +> **AI proposes. Code governs and executes.** +> The agent is generative — it reads your business in plain language and proposes the action. The validator is a *deterministic function* — the NIL kernel — that lowers the proposal to an executable, content-hashed plan **or refuses it with a precise reason**. A hallucinated verb has nothing to bind to. An undeclared action is *unexpressible, not filtered*. + +Every section, no matter the segment, is a different lens on that one sentence. + +### 1.2 The six segments and their distinct AHA + +| # | Segment | The moment they say AHA | Primary interactive proof | Copy register | +|---|---|---|---|---| +| 1 | **Business owner / operator** | "I can *talk* to my business and it just… runs itself — safely." | Live **Talk-to-automation** console demo (type a sentence → watch a governed plan assemble). | Plain, outcome-first, bilingual. | +| 2 | **Finance / accounting** | "Every write is previewed, approved, reversible, and on the record — I can't get burned." | **Governance timeline** + **rollback** demo (a bad write, then an *honest* compensation). | Trust, audit, compliance (EU AI Act framing). | +| 3 | **Operations / procurement** | "One canvas wires Odoo → Books → WhatsApp, and it refuses a broken wire *in the editor*, not at 3am." | **Cross-system canvas** demo (React-Flow-style, validates a dangling wire in place). | Concrete, cross-system, reliability. | +| 4 | **Developer / integrator** | "Build one adapter, and every agent can operate it. Here's `pip install`, here's a real propose→commit trace." | **CLI + propose→commit trace** (ported from nilscript-landing, warmed up). | Hands-on, spec-first, no waitlist. | +| 5 | **AI lab / agent builder** | "The agent is *structurally* sandboxed to propose-only — 0.00% unauthorized writes by construction." | The **O(n)→O(1) risk-collapse dials** (ported Aha Act 4) + the InjecAgent bench. | Rigorous, adversarial ("try to break it"). | +| 6 | **Investor / press / decision-maker** | "This is a *category* — governed automation — with a live MENA commerce wedge and an open-standard moat." | The **category map** (three-camps animation) + traction band. | Strategic, category-defining. | + +### 1.3 How a visitor gets routed to their AHA + +Three concurrent mechanisms, no forced choice: + +1. **A single scrolling spine everyone sees** — the thesis, the live demo, the proof.

Picking a card doesn't navigate away; it **re-themes and re-orders the page** (Framer `layout` animations reflow sections, swap the hero sub-headline, and promote that segment's demo to the top). URL syncs to `?for=finance` (URL-as-state, per web/patterns). +3. **Deep segment pages** (`/for/[segment]`) for anyone who wants the full argument — the six `audiences/*.md` files in `nilscript-landing`, re-authored for the *product* and animated. + +--- + +## 2. Tech stack (decided, with rationale) + +| Concern | Choice | Rationale | +|---|---|---| +| Framework | **Next.js 15 (App Router) + React 19 + TS** | Matches `wosool-hub` (React 19), one version ahead of `nilscript-landing`. SSG/ISR for marketing SEO; RSC for the static shell, client islands for demos. | +| Styling | **Tailwind CSS v4 + CSS custom-property token layer** | Same model as both repos. Tokens as CSS vars (web/coding-style). Reuse the hub's oklch palette so the site *matches the product*. | +| **Animation (the point of this repo)** | **Framer Motion (motion/react) as primary** + a small **GSAP + ScrollTrigger** layer for the scrollytelling timelines + **Lenis** for smooth scroll | Brief demands "rich animation framer + rich interactive animation A LOT". Framer for component/gesture/`layout`/`AnimatePresence`; GSAP+ScrollTrigger for pinned, scrubbed, multi-act sequences where Framer's scroll API is weaker; Lenis for the buttery scroll that makes scrubbing feel designed. | +| Interactive graph/canvas demo | **@xyflow/react (React Flow)** | Same lib the product uses (`/canvas`, `/graph`) — the landing demo is *visually identical to the real thing*, which is itself a trust signal. | +| Chat/console demo | Custom lightweight typewriter component (NOT `@assistant-ui`) | The product uses assistant-ui; the landing only needs a *scripted, deterministic* fake of it — lighter, no backend. | +| Icons | **lucide-react** | Both repos already use it. | +| i18n / RTL | **next-intl** + `dir` switching + logical CSS properties | Bilingual ar/en is a first-class requirement (the wedge is MENA). RTL is designed-in, not retrofitted. | +| 3D (optional, budgeted) | **React Three Fiber + drei**, lazy-loaded, one hero moment only | One tasteful 3D "governance boundary" object in the hero, code-split and gated behind `prefers-reduced-motion` + a low-power check. Not load-bearing. | +| Fonts | **Inter** (sans) + **JetBrains Mono** (governed/audit surfaces) + **IBM Plex Sans Arabic** (RTL) | Exactly the hub's stack — the audit/mono surfaces should *read like infrastructure you trust* (VISION §8.8). | +| Analytics | Plausible or PostHog (privacy-first), segment-tagged events | Measure which segment card → which demo → which CTA converts. | +| Deploy | Static/ISR export → the shared Hetzner Caddy (like `wosool.ai`), new host `get.wosool.ai` or `wosool.ai` apex | Consistent with existing NIL deploy topology; additive to shared Caddy. | + +**Reduced-motion is a hard requirement, not a nicety.** Both existing repos already gate on `prefers-reduced-motion`; every animation in this plan ships a static/instant fallback.

Lazy-loaded; falls back to the CSS particle-stream (ported from `nilscript-landing/aha/stream.tsx`) on reduced-motion/low-power. + - A magnetic cursor pull on the primary CTA (Framer `useMotionValue` + spring). +- **Lands:** everyone (ambient), owner (headline). + +### S2 — The tension: "Two broken camps." (category set-up) +- **Content:** VISION §1/§3 three-camps table as a living diagram: *Deterministic-but-manual* (Zapier/n8n) vs *AI-but-ungoverned* (Lindy/browser agents) — and the wedge **between** them. +- **Interaction:** GSAP ScrollTrigger **pinned** scene. As you scroll, two columns slide in from left/right, collide, and a glowing seam opens between them where the Wosool wedge materializes. Scrubbed (progress-linked), not autoplay — the user *drives* the reveal. +- **Lands:** investor, owner, ops. + +### S3 — Live demo #1: **Talk-to-automation console** (the headline AHA) +- **Content:** A faithful, *scripted* replica of the product `/ask` split-view (VISION §8.2): chat left, **"what the code decided"** right. +- **Interaction (the signature moment):** + 1. Pre-filled prompt types itself: *"Every Won deal in Odoo → make an invoice and ping finance."* (bilingual variants). + 2. The agent "thinks" (shimmer), then the **right panel assembles the governed plan node-by-node** with spring pop-in: `stage 1 · Odoo · crm.read_deal → stage 2 · Books · acc.create_invoice`, handoff `deal.total → amount`, trigger `on deal.stage = "won"`, **tier: REVERSIBLE · hash a3f8…**. + 3. A **[try your own]** mode: the user can pick from ~6 canned sentences; one of them intentionally names a fake verb (`crm.fly`) → the right panel throws the **structured refusal** `✗ V4 crm.fly: not a declared verb` with a red shake. *This is the "unexpressible, not filtered" AHA made tactile.* + 4. `[Approve]` button → green ripple → the plan collapses into a compact "armed automation" card that flies up into a "your tools" shelf. +- **Tech:** deterministic state machine, Framer `AnimatePresence` + `layout` for the fly-to-shelf; no real backend. +- **Lands:** owner (primary), finance (sees the tier + approval), everyone. + +### S4 — The machine: **propose → govern → commit → audit** +- **Content:** The tri-layer (VISION §7): agent (generative) → NIL kernel (deterministic validator V1–V6) → backends. The four structural guarantees (Constitution §6) as four cards. +- **Interaction:** A horizontal **scroll-scrubbed conveyor**: an intent token rides left→right through four gates; each gate lights and stamps it (previewed → tier-checked → content-hashed → read-back). At the "undeclared verb" fork, a token visibly *loses its representation* and vanishes (`β⁻¹ = ∅`). GSAP timeline pinned; each guarantee card flips (Framer `rotateY`) as its gate activates. +- **Lands:** developer, ai-lab, finance. + +### S5 — Live demo #2: **Cross-system canvas** (the ops AHA) +- **Content:** A real **React Flow** canvas with 3 nodes (Odoo `create_lead` → Books `create_invoice` → WhatsApp `notify`), governance badges on each node (REVERSIBLE/COMPENSABLE/IRREVERSIBLE + tier chip). +- **Interaction:** The user can **drag a new wire**. Drawing a valid handoff snaps green. Drawing a **dangling/forward wire** snaps **red and is refused in place** with an inline diagnostic — exactly the product behavior (VISION §8.3). A verb dropdown populated "live" (from a static skeleton fixture) shows you can only pick declared verbs. Minimap, draggable nodes — same feel as `/canvas`. +- **Lands:** operations (primary), developer. + +### S6 — Live demo #3: **Governance timeline + honest rollback** (the finance AHA) +- **Content:** The productized control-plane timeline (VISION §8.7 / §9): an append-only, HMAC-verified log; a HIGH-tier write parks for approval; a wrong write gets **rolled back via a real compensation** (never a faked undo). +- **Interaction:** A vertical timeline where each event card slides in (`whileInView`). One CRITICAL row has a **cooling delay** countdown ring. A **[Roll back]** button on a reversible row triggers an animated compensation: the original write and its inverse are drawn as a matched pair, and an IRREVERSIBLE row's rollback button is visibly disabled with the honest tooltip *"cannot fake an undo it can't do."* This honesty is the trust AHA. +- **Lands:** finance (primary), decision-maker, owner. + +### S7 — **Risk collapses: O(n) → O(1)** (the AI-lab AHA) +- **Content:** Ported and warmed-up from `nilscript-landing/aha/synthesis.tsx`: the interactive dials showing filter-risk `1 − (1−ε)^n` growing with checkpoints vs. NIL's structural `0` by construction. Plus the InjecAgent headline: **0.00% unauthorized writes across 2,108 evals** (Constitution §6 / benchmark). +- **Interaction:** Two range dials (`n` checkpoints, `ε` leak rate); an SVG risk curve re-renders in real time (Framer `useMotionValue`); at the end the whole probabilistic curve **collapses to a flat zero line** with a satisfying snap. "Try to break it" framing. +- **Lands:** ai-lab (primary), security-minded finance, developer. + +### S8 — **Proof it's real** + traction band +- **Content:** Constitution §"Why it is real": 18-platform / 90-row calibration; ERPNext self-adoptable proof; running-in-production. Live MENA wedge (Salla/WhatsApp/Arabic-native) as the distribution edge. +- **Interaction:** A **counter band** (numbers count up on view — 18 platforms, 90 rows, 2,108 evals, 0.00%), an animated world-to-MENA map zoom, logo/adapter marquee (Odoo, Salla, PocketBase, ERPNext) with a subtle infinite scroll. +- **Lands:** investor, decision-maker, everyone (credibility). + +### S9 — **Find your path** (the interactive segment selector) +- **Content:** Six cards (the §1.2 table). This is the re-router (§1.3). +- **Interaction:** Bento-grid of 6 cards; hover tilts (3D `rotateX/Y` on pointer). Click → the card expands (`layout` shared-element) into a mini-pitch + its demo, and the page re-orders to promote that segment (URL → `?for=`). A "reset" returns to the neutral spine. +- **Lands:** the mechanism that lands *all* of them. + +### S10 — Pricing (open-core, honest) +- **Content:** Constitution §11: the **standard is free** (CC BY 4.0, `pip install nilscript`); the **commercial layer** is the hosted control plane + certified-adapter network.

Risks & open questions + +1. **Animation overload vs. clarity.** "A lot of animations" can tip into noise. Mitigation: the shared motion grammar (§5.1), one signature motif (the membrane) reused, and a rule — *motion only where it clarifies the propose→govern→commit flow* (VISION §8.8). Every section must justify its motion or lose it in review. +2. **Demo fidelity vs. reality.** Scripted demos must match real product behavior or the trust breaks (same risk as VISION §13.1 canvas↔DSL fidelity). Mitigation: mirror the hub's actual components/verbs/refusal codes; label demos "interactive preview". +3. **Positioning discipline.** Easy to blur into "another AI workflow tool" (VISION §13.5). Mitigation: lead every section with generate-vs-govern; Constitution §14 lint on all copy. +4. **Standard vs. product line.** The site sells Wosool but must not misrepresent itself as the standard (Constitution §11). Mitigation: the persistent NIL-credit line + `nilscript.org` handoff; English-only claims about the *standard*, bilingual claims about the *product*. +5. **Perf budget under heavy motion.** R3F + GSAP + React Flow + Lenis is a lot of JS. Mitigation: aggressive code-splitting, below-the-fold hydration, the CWV gates in §5.4 as CI checks (Lighthouse budget assertions). +6. **RTL QA is the known weak spot** (the hub's own gap list flags "RTL QA incomplete"). Mitigation: RTL is a first-class P0 concern here, logical properties from day one, dedicated RTL QA pass in P7. + +--- + +## 13.

The category (locked) + +NIL is the governed action layer that tool-integration standards leave undefined. MCP and OpenAPI +standardize what an agent can reach. NIL governs what an agent can author. NIL composes with them; it +does not replace them. The failure mode this prevents is being filed next to MCP (an integration +layer) or next to guardrails (a probabilistic filter). NIL is neither. + +## 3. Taglines and slogans (locked) + +- Primary tagline: Unexpressible, not filtered. +- Descriptor line: The governed action layer for AI agents. + +Lead with the primary tagline where there is room for one striking line; use the descriptor line where +the reader needs the category in plain words. NILScript is an open international standard: all public +positioning and marketing surfaces are English-only. (Arabic is not banned inside product surfaces +that are themselves Arabic-market, such as Wosool, or inside technical examples of the locale-driven +bilingual preview; it is simply not used to brand the standard.) + +## 4. Vision + +AI agents are moving from writing text to taking actions on the systems a business already runs. The +barrier is not capability; it is trust. NILScript exists so that an organization can let an agent +operate its real systems without having to trust the agent, by moving the trust boundary to the +server and making the unauthorized action impossible to commit rather than merely discouraged. The +long-term aim is for NIL to become the default action layer between agents and backends, the way TLS +became the default for transport. The path runs through MENA and Arabic-native commerce first, then +outward. + +## 5. Mission and goal + +Make the unauthorized or hallucinated action structurally uncommittable on real backends, give any +backend a build-once governed adapter, and keep the NIL specification open so it spreads. The standard +stays open to win ubiquity; the commercial value lives one layer up, in the hosted control plane and +the certified-adapter network (section 11). + +## 6. What NIL is (the four structural guarantees, in plain words) + +1. No side effects on propose. An agent emits intent, not an action. Proposing leaves the backend + byte-identical. Only an approved commit changes state. +2. Skeleton-bounded. An agent can only name verbs and targets the backend has declared. An undeclared + verb or target has no representation to send. The bound covers the generic CRUD family, so + advertised equals committable. +3. Honest, bounded reversibility. Every write declares whether it is reversible, compensable, or + irreversible, and a rollback runs a real compensation through the same machinery. The system never + fabricates a corrective write and never pretends an irreversible effect can be undone. +4. Earned, not asserted. A success envelope is confirmed by reading the record back; a reversibility + tier is confirmed by a conformance run. An adapter that claims a property its run does not honour + fails admission. + +The formal core: an undeclared action has empty preimage under the binding (beta^{-1}(a) = empty). +This is strictly stronger than filtering, where the action can be named and a classifier admits it +with nonzero probability. + +## 7. What NIL is NOT (anti-positioning) + +- Not "OpenAPI for agent actions." OpenAPI and MCP describe a surface so a client can call it; the + agent still authors the call. NIL removes the agent's ability to author an undeclared call at all. +- Not an "agentic firewall" or a guardrail. A firewall or guardrail inspects a namable action and + blocks it with some probability. Under NIL the unauthorized action is not namable. If "firewall" is + used as a hook, it must be followed immediately by "but structural, not a filter." +- Not "makes agents safe or trustworthy." NIL does not make the model correct. NIL makes the + unauthorized action uncommittable, not the agent wise. +- Not a replacement for MCP. NIL composes with MCP as the governed action layer MCP does not define. + +## 8. How NIL relates to the things people already know + +- MCP / OpenAPI / function-calling: integration layers (discovery and invocation). NIL sits underneath + the effect and governs it. +- Guardrails (classifiers, policy prompts): probabilistic per-step filters over a namable action. NIL + is a single structural boundary; the rate is zero by construction, not small by tuning. +- OAuth / server-side authorization: the closest correct analogy. NIL is authorization for agent + writes, enforced at the effect boundary on the server, independent of the model. +- "USB for systems": the adapter analogy; always paired with the governance point. + +## 9. Naming and terminology lock + +- NILScript: the project, the standard, and the reference package. One word, capital N-I-L, capital S. +- NIL: the contract itself. Acceptable on its own after first defining NILScript. +- NIL expands to Network Intent Layer. The lower layer is a wire contract; the upper, optional layer is + a declarative orchestration language. "Layer" names the whole. +- Wosool: the commercial reference implementation, never a synonym for NILScript (section 11). + +RATIFY: earlier notes recorded "Network Intent Language." The published paper, the Zenodo record, and +the DOI all use "Network Intent Layer." This file locks Layer because it matches the published, +citable artifacts. Default and recommendation: keep Layer. + +## 10. The honesty clause (governing) + +- The zero unauthorized-write result is by construction within the threat model, confirmed on a live + backend, not a surprising empirical rate. +- The structural guarantee holds only while NIL is the sole effect path. +- On the kernel API path the kernel performs the confirmation and read-back; on the MCP path the + confirmation currently rests on the agent's mechanism and the adapter envelope, gated at admission + but not yet re-verified per request. Kernel-side re-verification on that path is future work. + +Any source that drops these boundaries to sound stronger is off-constitution. + +## 11. Standard versus product (open-core) + +- NILScript (the standard) is open (CC BY 4.0). Ubiquity is the goal; a wide adapter ecosystem is the + network effect. +- The commercial layer is the hosted control plane and the certified-adapter network, not the spec. +- Wosool is the first commercial reference implementation: an AI operations layer for Salla merchants + in MENA (WhatsApp-native, Arabic-native). Wosool is built on NILScript; it is not NILScript. + +## 12. Audience register (same truth, three depths) + +- Developer: "An agent proposes intent over NIL; a deterministic kernel commits only declared, + approved writes, and reads the result back. Build one adapter per backend; any agent can then operate + it without being trusted. `pip install nilscript`." +- Enterprise / government buyer: "A server-side authorization layer for agent actions. Writes pass a + declared propose-approve-commit lifecycle with an auditable trail; an undeclared write cannot be + issued. Deployable on-premises; the governance boundary is enforced in code, not in a prompt." +- Investor: "The governed action layer for AI agents.

Enterprises can't + trust it on production systems. + +**Our wedge sits exactly between them:** the **agent is generative** (it reads your business in plain +language and proposes the action or the workflow), but the **validator is a total, deterministic +function** — the NIL kernel — that lowers the proposal into an executable, content-hashed plan *or +rejects it with a precise reason*. A hallucinated verb has nothing to bind to. A composed workflow +that names an undeclared op is refused before any effect occurs. + +> **AI proposes. Code governs and executes.** That sentence is the whole product. + +This is not a feature of an automation tool. It's a different *category*: **governed AI automation** — +the safe hub that lets a company point Claude/Hermes at its real systems and say "automate this," and +get a deterministic, reversible, audited result. + +--- + +## 2. The problem we solve + +A company runs Odoo (with 10 modules), maybe Salla, maybe a custom system. The owner knows exactly +what they want — *"every morning, take yesterday's new leads, create a follow-up task, and post the +totals to accounting"* — but: + +- Building that in n8n means learning n8n, mapping every field, and owning the breakage. +- Handing it to an LLM agent means trusting a probabilistic model to write to their books. +- Cross-system ("sales → marketing → accounting") multiplies both problems: schema mismatch + + authority leakage. + +**The barrier is "describe → safe running automation."** We collapse it: the owner *describes* (talks +or draws), the agent *proposes*, the kernel *governs*, and the result is a **reusable, self-triggering +automation** they can forget about — that re-runs itself reproducibly and shows every action in one +audited pane. + +--- + +## 3.

Today's tools bolt governance onto +the *context/prompt layer* (what enters the window). **NIL enforces it at the *effect* layer** — the +one place that actually matters: nothing writes unless it was declared, previewed, and (optionally) +approved. That is a structural guarantee, not a softer "the model decided not to." + +**Conclusion:** the AI-native builders are racing on *capability*; the MCP bridges are racing on +*connectivity*; **nobody owns governed determinism as the product.** That's the category we take. + +Sources: [Lindy — AI automation platforms 2026](https://www.lindy.ai/blog/ai-automation-platform), +[Gumloop review](https://automationatlas.io/tools/gumloop/), +[Berkeley CMR — Governing the Agentic Enterprise](https://cmr.berkeley.edu/2026/03/governing-the-agentic-enterprise-a-new-operating-model-for-autonomous-ai-at-scale/), +[Atlan — Enterprise AI Agent Guardrails](https://atlan.com/know/ai-agent/enterprise-ai-agent-guardrails-checklist/), +[Runtime Governance for AI Agents (arXiv)](https://arxiv.org/html/2603.16586), +[mcp-server-odoo](https://github.com/ivnvxd/mcp-server-odoo), +[Odoo MCP Framework](https://apps.odoo.com/apps/modules/18.0/mcp_base). + +--- + +## 4. What the platform IS — five pillars + +The hub does five things, each backed by something we already built in the kernel: + +1. **Connect systems** — adapters turn any backend (Odoo, Salla, PocketBase, custom) into a + NIL-speaking surface. *(kernel: scaffold + edge template + Choice Gate.)* +2. **Connect agents** — MCP front door binds Claude/Hermes/any MCP client to the governed tools. + *(kernel: multi-tenant MCP server.)* +3. **Propose** — the agent emits intents/plans as data; the kernel previews them (no side effect). + *(kernel: propose/commit, refusals, the V1–V6 validator.)* +4. **Execute & automate** — a single governed op runs now, **or** a plan is registered as a + versioned, self-triggering automation. *(kernel: the Automation Registry + dispatcher + triggers + + cross-system composition — shipped.)* +5. **Govern** — one audited timeline, approval gates, honest reversibility, content-hash version + locks. *(kernel: control plane + audit store.)* + +The *new product* is the **surface** over these: a native dashboard, a conversational console, and a +visual builder — multi-tenant, beautiful, and opinionated. + +--- + +## 5. Three ways to create an automation + +The same governed engine, three front doors — meet the user where they are: + +### 5.1 Talk (conversational) +The owner opens the console and says: *"In my Odoo, whenever a deal moves to Won, create an invoice +and notify the finance channel."* The agent (Claude/Hermes) reads the request + the live capability +registry, **proposes** the op or the workflow, the kernel lowers-or-rejects it, the owner sees a plain +preview and approves. → a running automation. + +### 5.2 Draw (visual canvas) +For people who think in boxes: a node canvas (n8n/Gumloop-familiar) where **every node is a governed +NIL op**, not a raw API call. Drag a "create lead (Odoo)" node, link it to a "create invoice (Books)" +node, draw the data handoff, set a trigger, hit save. The canvas **validates live** against the real +backend skeletons; an invalid wire is refused in the editor, not at 3am in production. + +### 5.3 Direct (API / agent tool) +Power users and other agents hit the registry API or the MCP automation tools directly. + +> All three converge on the **same SSOT record**: a content-hashed, versioned, validated automation. +> The mode is just ergonomics; the guarantee is identical. + +--- + +## 6. The core loop — *create once, then forget* (automation-as-a-tool) + +This is the idea that changes how business is done: + +``` +describe ─▶ agent proposes ─▶ kernel validates (deterministic) ─▶ human approves ─▶ REGISTERED + │ + ┌────────────────────────────────────────────────────────┘ + ▼ + it becomes a self-running CAPABILITY: + • fires itself (schedule / event) — you forget it + • OR is invocable on demand as a NEW TOOL the agent can call + (no re-reasoning, no re-building — the workflow IS the tool) +``` + +The breakthrough: **a validated automation is promoted to a callable tool.** The next time the agent +needs "onboard a customer across Odoo + Salla," it doesn't re-derive the steps — it calls the +*existing, governed, version-locked* automation. The agent's reasoning compounds into a growing library +of safe, reusable, self-triggering capabilities. **The company's processes become living, governed +software — authored by conversation, owned by the code.** + +--- + +## 7.

Where the moat actually is (the section the first draft never wrote) + +A moat is the thing none of the five — and not Microsoft, and not Google — copies in a sprint. By +definition it is **not in the spec**, because the spec is public and the parts are decades old. It is in +the commercial layer the constitution already names as the real value (open-core §11) and that this +"NIL-vs-the-field" framing made invisible: + +- **Arabic-dialect intent resolution** — Gulf/Levantine/Egyptian commerce phrasing → governed action. A + US-based banking-agent CTF and a Microsoft toolkit do not have this and will not build it for MENA. +- **The cross-merchant WhatsApp customer-identity graph** — who the customer is across Wosool merchants, + reconciled. This compounds with every merchant and conversation; it is a data asset, not a feature. +- **The Salla integration** — the actual, working governed adapter into the platform MENA merchants run + on. Distribution, not spec. +- **Retained merchants who trust the automation** — ten merchants who keep Wosool because the writes are + safe *and the dialect/identity/Salla pieces work.* That trust is the only thing in this entire + document a competitor cannot replicate by reading a paper. + +Reversibility and earned-read-back matter here — not as a standard to defend, but as the **reason a +merchant trusts Wosool to act on their store.** That is their correct job. The triad describes the +safety; the moat is the distribution, the data, and the trust the safety *earns*. + +--- + +## 8. Answer to the two questions that prompted this: neither + +> "Fold the roadmap into the Positioning Constitution, or open the standards-alignment appendix?" + +**Neither.** Both are standard-race work; the standards appendix is the worst offender — maximum +effort-signaling toward an enterprise crown NIL isn't contesting, zero effect on merchant retention. + +The single NIL action worth taking is **keeping the honest positioning paragraph** (triad = +differentiation; 0% = entry price; unexpressibility = bounded to undeclared verbs) as the *description of +Wosool's safety* — and that's already done, in this file. Then **close the NIL-strategy tab** and spend +the hours on Arabic intent, the WhatsApp identity graph, Salla, and the next retained merchant. + +--- + +## 9. One-paragraph synthesis + +The field ratified NIL's bet five times in four months — validation, but also commoditization of "a +deterministic gate that yields 0%." NIL's triad is genuine differentiation and zero moat: unexpressibility +is the 60-year-old object-capability model narrowly scoped (the 224 incident is its fence); bounded +reversibility is the 40-year-old Saga pattern that Microsoft already names; earned read-back is a +useful but sprint-copyable read-after-write check. Holding three copyable things together is a checklist, +and competitors with more engineers than NIL has hours match a checklist in a sprint. The roadmap that +chases the others' enterprise features — especially a NIST/EU-AI-Act standards appendix — is excellent +execution of the strategy already abandoned. Use the triad as honest *marketing copy* for why Wosool's +writes are safe; keep the 0% honest; and put the engineering hours where the actual defensible asset +lives — Arabic-dialect intent, the cross-merchant WhatsApp identity graph, the Salla integration, and +ten merchants who trust the automation.

Adapting them all to a single model would require either: +1. A least-common-denominator interface (too weak) +2. An adaptation layer that converts between APIs (adds complexity) +3. Separate adapters with a shared contract (proven approach, used by messaging frameworks) + +We chose option 3. Each adapter is self-contained, making it easy to add new channels without touching existing ones. + +### Q: Why is the mobile app a "thin terminal" and not a full cycle editor? + +**A**: Editing cycles requires schema knowledge, validation, testing, and version control. The web UI is the source of truth. The mobile app's job is to *execute* cycles and *approve* steps — not author them. This keeps the mobile client simple and ensures all cycle changes go through the web UI with proper oversight. + +### Q: Why do permission cards render differently per channel? + +**A**: Each channel has different UI constraints and user expectations: +- WhatsApp: max 3 interactive buttons, no HTML +- Slack: rich Block Kit with color, sections, context +- SMS: 160-char limit, numeric codes +- Email: HTML + plain text, links work + +Forcing all channels to the same rendering would either look generic (bad UX) or exceed channel limits. Channel-native rendering respects each platform's strengths. + +### Q: How does correlation handle ambiguous messages? + +**A**: Phase 3 will implement: +1. Scoring algorithm (combine multiple signals) +2. Confidence thresholds (high → auto-add, medium → human review, low → reject) +3. User confirmation UI (show top-N candidates, let user pick) + +For MVP, we'll require explicit thread linking (e.g., include business_ref in message or reply to a thread message). + +--- + +## Dependency Graph + +``` +adapter_contract.py + ├─ models only (Pydantic) + ├─ no external channel libraries + +invocation_parser.py + ├─ dataclasses + ├─ re (regex) + └─ no external dependencies + +permission_card_renderer.py + ├─ adapter_contract.py (types) + ├─ dataclasses + ├─ datetime + └─ no external dependencies + +mobile_terminal.py + ├─ Pydantic models + ├─ Enum + └─ no external dependencies + +test_wave8_channels.py + ├─ all modules above + └─ pytest, pytest-asyncio +``` + +All modules are framework-agnostic.
