Summary

Phase 1 of multi-tenant SaaS (PLAN-saas-multitenant): close the isolation hole where a request's tenant came from the free x-nil-workspace header — anyone could set it and read any workspace's data via registry routing.

resolve_tenant gains a SaaS mode:

  • tenant = the authenticated identity via an injected claim_resolver (verified JWT workspace claim)
  • the x-nil-workspace header cannot override it (mismatch → refused)
  • a BYO x-nil-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 resolver — it can never silently fall back to header-trust.

Isolation conformance (the point)

  • tenant A and B route to different adapters
  • a header naming B under an A token → refused
  • BYO adapter-url in SaaS → refused
  • missing claim → default-denied
  • unknown workspace → no adapter

25 mcp/tenant tests green; 105 green across mcp/tenant/intent/router.

Scope / honesty

This is the identity spine only (the decision we agreed: build this first). The production claim_resolver (keycloak JWKS JWT verifier) is the deployment wiring — intentionally not hand-rolled here. Remaining for full SaaS: tenant-scope the newer surfaces (intent router providers, export, automation, Hermes isolation), per-tenant quotas/rate-limits, and the encrypted per-tenant secret vault (decided: control-plane vault). Not merged = no deploy.

…er override, default-deny

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.
…quotas

Builds on the identity spine (#66). 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).
…ault

Onboarding for SaaS: a company is stood up in a single privileged call.

- store: tenant_secrets table + put/get/delete_secrets using the SecretVault (encrypted at rest,
  Fernet, NIL_VAULT_KEY); vault disabled (fail-closed) when no key. Secrets keyed by workspace.
- app: POST /tenants/provision (workspace + secrets + adapter → store secrets encrypted, register +
  activate adapter); GET /tenants/{ws}/secret/{name} (registry-token-gated server-to-server fetch of a
  tenant's decrypted secret for the platform — never the browser, never logged).

Tests: one-call provision activates the adapter + stores secrets; secret read is token-gated; secrets
are ciphertext at rest (no plaintext key on disk); tenants isolated; auth + workspace required. 164
cp/registry/tenant/saas tests green.
…oped durable layer

Closes the remaining SaaS items (kernel side):

- JWKS claim resolver (mcp/auth.py): production keycloak path — PyJWKClient fetches + caches signing
  keys, selects by kid (rotation-safe); fail-closed on any verify error. jwt_claim_resolver_from_env
  precedence: NIL_JWT_JWKS_URL > NIL_JWT_PUBLIC_KEY > NIL_JWT_HS_SECRET.
- Surface tenant-scoping: store.recent(workspace=) and store.pending(workspace=) (pending joins to its
  events' workspace, since approvals carries none); /api/events and /api/pending take ?workspace=.
  Conformance: tenant A's events/pending never include B's; operator view (no ws) sees all.
- Tenant-scoped durable layer (durable.py, Temporal-ready): tenant-prefixed deterministic workflow ids
  (idempotent + no cross-tenant collision), per-tenant Temporal namespace, TenantDurablePolicy
  (per-tenant rate + concurrency admission — the 429 fairness, durable edition). Worker integration
  is the separate Temporal build; this is the isolation layer it plugs into.

42 SaaS tests green (JWKS verify/forge, durable id/namespace isolation + per-tenant throttle, events/
pending workspace scoping); 161 across cp/registry/tenant/mcp.
…layer (Phase 6)

durable_temporal.py (optional — temporalio imported lazily): heavy/bulk governed writes run as DURABLE
workflows, tenant-isolated and crash-safe:
- per-tenant Temporal namespace + deterministic tenant-scoped workflow id (idempotent, no cross-tenant
  collision);
- the NIL gate runs in an activity with a RetryPolicy → a throttled (429)/transient backend is retried
  durably, not dropped (the 429 fairness lesson, durable edition);
- register_executor injects the NIL propose→commit (real SDK in prod, a fake in tests);
- run_worker starts a worker on the tenant's namespace + task queue.

Verified END-TO-END with temporalio's in-process time-skipping server (no external infra): a backend
throttled twice is retried and commits on attempt 3; workflow id is tenant-scoped + idempotent.

pyproject: [saas] (pyjwt[crypto] + cryptography) and [temporal] (temporalio) extras, wired into [dev].
148 durable/saas/tenant/cp/mcp tests green.
De-Salla'd Evolution API client (EvolutionClient) + deterministic per-tenant naming + error/QR/state extractors + config-from-env. 34 tests passing.
The canonical protocol object. Cycle embeds today's kernel Node union as its Flow (execution AST
reused verbatim) and adds intent/roles/policies/resources/outcomes. compile_cycle lowers Cycle ->
WosoolProgram IR and runs the UNCHANGED V1-V6 validator (governance invariant preserved); an
undeclared verb is refused through the lowering (V4). cycle_content_hash locks the version over the
AST, not the derived IR. policies.raises_tier=HIGH escalates a node to a human-approval gate (floor
only rises). 14 tests; full suite 527 green — governed core untouched.
…egisters THROUGH the kernel)

draft_cycle/register_cycle persist a drawn cycle the same way an automation is stored: compile
(lower -> V1-V6 -> AST content-hash) then append to the automations SSOT with kind='cycle' and the
canonical Cycle AST in a new nullable source column (lowered WosoolProgram stays in plan, derived).
Runs reuse fire_manual unchanged - no second executor. Control-plane gains POST /cycles/draft,
POST /cycles/register (pending_approval, never auto-armed, idempotent on hash), GET /cycles. 11 new
tests; full suite 538 green - store schema change backward-compatible.
…teps over a hidden IR

The Cycle is now the canonical protocol with its OWN richer step model, not an embed of the
execution IR: NAMED position-independent steps (CreateLead, not step_1), named outputs + variable
bindings, role-bound context actors, first-class approval nodes, decisions, tags. compile_cycle
LOWERS named steps -> step_N and named-output/variable refs (lead.id, payload.name) ->
$.step_N.output / $.input data references, then runs the UNCHANGED V1-V6 validator; WosoolProgram
stays the hidden IR (governed core byte-for-byte intact). Approval steps ARE the gates. CompileResult
exposes step_ids (name->IR id) for other projections. Worked SalesLeadLifecycle from the .nil mockup.
16 protocol tests; full suite 540 green. (Deferred: parallel/foreach/wait/call steps, imports,
contracts, metrics, Protocol Registry — YAGNI for v0.2.)
…hases 4-5)

Three projections over the frozen Cycle AST v0.2, all pure, no new deps:
- nil_printer/nil_parser: the .nil text surface. print_nil (canonical) + parse_nil (hand-written
  tokenizer + recursive descent, NilSyntaxError with line/col). 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).
Kernel suite 590 green.
cycle/lsp.py: diagnostics (parse + V1-V6, IR step_N reverse-mapped to protocol names for
line-accurate errors, + dead-references), context-aware completions (verbs after use, step names
after next/->, entities after approver:), hover, semantic_tokens. Pure, total (never raises).
CP: POST /cycles/{parse,print,lsp/diagnostics,lsp/completions,lsp/hover,lsp/semantic-tokens,
projections}. 12 LSP tests; kernel suite 602 green.
…ace column

The approvals table had NO workspace column; per-tenant /pending was faked by JOINing each hold to
its proposed event by proposal_id — a join that broke (proposal_ids in the ledger never matched the
approvals rows), so the owner's Decisions screen showed nothing while holds piled up globally.

Root fix: a held proposal now CARRIES its own workspace, recorded by the gate at hold-time
(mcp/tools.py -> /proposals/{id}/await -> store.await_approval(workspace=...)). store.pending(ws)
filters on that column DIRECTLY; the fragile events-join remains only as a legacy fallback for
pre-migration rows. Idempotent ALTER + best-effort backfill on boot. 602 tests green.
…isite mechanism

- control-plane: approvals carry resolved+modifiable; approve-with-edits re-proposes
  the amended args before commit (commit still executes exactly what was previewed)
- mcp gate: thread resolved+modifiable to the control plane at hold-time
- demo: pocketbase adapter gains the intent-contract + prerequisite gate (nil.* reads,
  flat resource.create, curated to_native delegation, tier inheritance, reference-existence
  refusal at propose)
- demo: point Odoo shim at the renamed odoo_nil_adapter package
- deploy: controlplane Dockerfile
…tion, materialize-on-commit

Control plane + store:
- register_planned_step: a dependent step whose handoff ref cannot resolve until
  its prerequisite commits is registered PLANNED (idempotent synthetic id), not
  proposed — it appears as a blocked card, never as an executable proposal
- record_committed + next_planned_steps + promote_planned_step: on a
  prerequisite's commit, resolve $.steps[N].result handoffs to the real backend
  id and materialize the dependents as HELD approvals ('propose only after the
  prerequisite commit')
- _shape_pending: expose resolved/modifiable JSON for the editable card and the
  computed plan blocked flag; cancel_plan rejects every un-decided step so
  rejecting any step leaves no orphans

MCP:
- nil_plan wiring for the planned/blocked lifecycle (+ tests)

Adapter (pocketbase reference):
- universal noun→declared-target resolution (concept synonyms, singular/plural,
  substring) — an agent naming 'res.partner'/'customer' resolves to whatever
  THIS backend declares; no per-backend hardcode, portable to every adapter

617 tests green.
…cribe

/nil/v0.1/describe gains verb_details[] — {verb, type, tier, reversibility,
doctype, entity_type, required_args, references} — the adapter's own authority
statement, sourced from its WriteVerb table + COMPENSATIONS (omission =
IRREVERSIBLE, the honest default). Optional in NIL 0.1: a non-declaring adapter
yields [] and consumers must treat its verbs as metadata-unknown (fail closed),
never guess tier/type from verb names.

- sdk/connect.handshake: passes verb_details through the connection report
- controlplane /api/adapter-skeleton: exposes verb_details alongside verbs
- demo pocketbase adapter: declares all curated + generic verbs
- tests: describe/handshake coverage (4 new)

621 tests green.
…riven resume

Invariant: a run that stops at a gate is PARKED, never lost. 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.
…waits

Invariant: a process can WAIT for the world (a supplier's mail, a payment
webhook) as a first-class, governed step — parked as a row, resumed by the
same ledger dispatch that fires event triggers, never an in-memory sleep.

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.
…lock (M1a)

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.
…medness (M1b)

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.
… (M2a)

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).
…cles (M2b)

Invariants enforced: wrap_cycle is PURE and deterministic (no timestamps,
no randomness), so re-wrapping an unchanged cycle yields the same
content-hash and the registry no-ops — no duplicate version; risk =
max over the cycle's step verbs using DECLARED adapter metadata only
(verb_details), an undeclared verb or garbage tier counts as HIGH and
an unreachable adapter floors everything at HIGH (fail closed, never a
name-substring guess); exposure is {ai:false} — flipping it stays a
deliberate governed act; archetype is OMITTED, not defaulted — no tag
beats a wrong tag; the generated strategy seq(approve(role: owner)) is
registered alongside its capability so the strategy ref never dangles,
and it is V9-clean by construction.

Endpoint: POST /capabilities/wrap {workspace, cycle_id} — auth-gated,
workspace-pinned (cross-tenant wrap is a 404). Spec deviation: the
'nilscript wrap-cycle' CLI is deferred — the registry lives behind the
control plane, so the endpoint is the honest surface (spec allows
endpoint and/or CLI).
…ture-slot rows (M3a)

One subject, N signature slots (strategy_signatures): Auto records a policy:<id> decision row
and refuses above MEDIUM at runtime (not just V9 bind time); Approve holds one addressed slot
whose timeout is a row deadline the tick sweep enforces (escalate re-addresses a fresh slot,
reject rejects the whole subject); Seq materializes item N+1 only on item N's approval and a
rejection anywhere cancels the rest; Quorum(k, distinct) commits only at k signatures from
distinct actors (and distinct declared identities); Conditional routes via the kernel's OWN
guard evaluator over $.input.* (no second evaluator). 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.

…+ endpoints (M3b)

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:<id>, 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.

Closes the two C4 live-mode gaps the hub integration surfaced:
- GET /prepared?workspace=&status= — the Decisions feed: the workspace's
  Permission Card envelopes newest-first, workspace-pinned fail closed (no
  workspace → 400; foreign workspace → empty), optional status filter
- rejection reason persisted on the prepared row (idempotent ALTER migration
  for existing DBs, same pattern as prior columns) and surfaced in the card
  envelope — a rejected card now says why

762 tests green (2 new).
…ding refuses drift (M4)

A3: `cycle X implements IssueInvoice@2.3 triggers … { }` — additive on the ONE v0.3 seam.
Decision: any v0.3-only construct (wait_for_event step OR implements clause) forces the
cycle/0.3 dialect, content-determined in BOTH directions, so the .nil parser still infers the
dialect with no surface marker and parse(print(ast)) == ast stays an exact bijection.
cycle/0.2 stays frozen and loadable; cycle_content_hash drops a None `implements` so every
pre-implements cycle keeps its version lock byte-identical.

A4-V7 (capability/conformance.py, pure, V1-V6 ValidationResult shape so the hub renders
refusals unchanged):
  V7_UNKNOWN_CAPABILITY   registry target missing, or a different id/contract version
                          resolved (fail closed - conformance against the wrong contract
                          proves nothing)
  V7_INPUT_UNPRODUCIBLE   a REQUIRED capability input has no name in the cycle's
                          trigger-match/context/variables namespace
  V7_OUTPUT_UNBOUND       a declared output no step's `output` ever binds
  V7_FLOOR_WEAKENED       floor-only-rises (I3), interpretation documented in the module:
                          NOT max(step tiers) >= risk as an equation - when the floor is
                          HIGH/CRITICAL the cycle must present a gate at/above it: an
                          approval step, a DECLARED verb tier >= floor (undeclared = HIGH,
                          fail closed, same rule as wrap_cycle - honest because the runtime
                          gate parks undeclared commits), or a policy raising a step there.
                          Refusal lands at the offending step (node), like V1-V6.
  V7_COMPENSATION_MISSING capability promises compensation but a write step has no
                          `compensate` and no checkpoint boundary exists (B5-ready seam)

Control plane: /cycles/register runs V7 when the AST carries `implements` - registry lookup
workspace-pinned, refusal stores nothing; /cycles/draft stays the V7-free preview.

Tests: 31 new (bijection both ways incl. patch versions, dialect seam both directions, every
V7 clause pass+refuse, workspace pinning, inline floor refusal at the step). 793 total green.
…osal (B5, M5)

A3: `step Phase1Done { checkpoint "order-placed" next Track }` — a v0.3 step on the same
content-inferred dialect seam (checkpoint => cycle/0.3; v0.2 frozen), parser/printer exact
bijection, name required and UNIQUE per cycle (duplicate names are unrepresentable — the name
is the rollback address). Lowers to a new CheckpointNode in the IR; V1-V6 unchanged.

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.
…le + tick sweep (B7 nil_schedule substrate)

A schedule is a row (scheduled_executions), never an in-memory timer: registered
only for pending/approved cards with a future ISO-8601 'when' (past timestamps
refuse with PAST_SCHEDULE), swept by the same /automations/tick clock as parked
runs and signature deadlines, and fired through the ONE shared execute path
(_execute_prepared_core, now also backing POST /prepared/{id}/execute). Outcomes
settle on the row (fired | refused) with the claim guard so overlapping ticks
never double-fire; a strategy unsatisfied at fire time records NOT_APPROVED as
the answer — never a silent retry.
…are/execute/schedule (B7, Gate M6)

The model's tool surface stays FIVE regardless of catalog size; zero raw verbs
reach it. CapabilityTools relays to the control plane (registry SSOT, typed
contracts, strategy interpreter, the one gated commit path):

- nil_discover: pure-code ranking (alias exact/substring in EN+AR, intent/
  example word overlap, domain filter), published + exposure.ai ONLY (draft/
  hidden never surface — fail closed), max 8, deterministic order, honest
  empty ('do NOT fall back to raw verbs').
- nil_inspect: full contract + strategy summary + content-hash.
- nil_prepare: card envelope; INPUT_CONTRACT refusals pass through with field
  lists as answers.
- nil_execute: NOT_APPROVED returns 'awaiting signatures — a human must sign
  in Decisions', never retried.
- nil_schedule: one-shot row over the a98b0f6 substrate; PAST_SCHEDULE refuses.

Registered in BOTH surfaces (the capability plane is the model-facing plane;
verb tools stay behind the builder flag); absent entirely when no control
plane is configured. SKILL.md gains the discover → inspect → prepare → HUMAN
approves → execute discipline; verb-level docs kept for builder mode.
…e the .nil bijection

ActionStep has carried retry, on_error, and compensate since the v0.2
freeze, but the printer never emitted them and the parser never read them
— a cycle using any of them failed parse(print(ast)) == ast, breaking the
canvas⇄.nil SSOT trust contract.

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.

Tests: 836 -> 858 green (each field individually, combined, canonical
form/order, refusals, registry + LSP wiring, hash pinning).
…ate, permanent

tests/test_p0_gate_demo.py IS Gate P0 (MVP-EXECUTION-PLAN.md, quoted in the
module docstring): a 3-step cycle (query -> HIGH write -> notify) registered
as a capability runs live end-to-end, all in mock mode with zero credentials.

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). One honest sequencing note is documented: the
two-key card gates the FIRING; the HIGH write parks on the second, verb-tier
gate — governance is layered.

Tests: 858 -> 859 green.

…tes (Wave 4 §14.2)

The anti-explosion spine (Encaps D7 / Risks 3,5,8): pure functions over the WHOLE capability set that
a single Capability can't check about itself — pinned SemVer (this is how `latest` is rejected at the
registry), one canonical concept (consistent owner/domain per id, no forked body at a version), and an
acyclic dependency DAG (cycle detection with a witness path). Designed as executable invariants
(Master Plan E1): the registration endpoint will call validate_registry(existing + candidate) and
reject any violation naming the candidate. 13 tests. First implementation brick of the Wave 4
Constitution; nothing downstream (Skill/Domain/DSL/compiler) is stable until this gate is.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
… §14.2b)

The register endpoint now runs the registry gate before persisting: a candidate that would introduce a
new SemVer or dependency-DAG violation is refused 409 with the violating witness, else it registers as
before. The candidate replaces its own id (register supersedes), so a legitimate supersede never
self-collides and a pre-existing registry issue never fails an unrelated registration; the gate fails
OPEN on its own internal error (governance must not brick the registry). Audited against the live
ws_acme catalog (45 capabilities) first — 0 violations, so enforcement is non-breaking. 3 endpoint
tests (cycle→409 + not stored, acyclic allowed, supersede allowed).

…inding (Wave 4 §14.3)

Introduces the Domain AST (domain/0.1): a curated business area that IMPORTS capabilities by alias at a
pinned major (Encaps D2 — the DI/permission boundary; `latest` is unrepresentable since major is an int)
and BINDS a backend per capability (D8 — the explicit multi-ERP routing decision that replaces the
implicit newest-declarer-wins in os-server RoutingNilClient; Procurement.Crm→odoo vs Finance.Crm→sap,
both Card-visible). The model makes an ambiguous alias / unbound / double-bound capability
unrepresentable; resolve_alias + resolve_backend are the exact lookups the compiler will perform (it
fails the compile when either returns None). Pure, no existing code touched. 11 tests.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…ve 4 §14.3b)

Adds the Skill sub-layer of a Capability (Encaps D3/D5): `Skill` = one named operation (send/receive/
notify) with input/output schemas, semantic-first `resolves_to` verb candidates, and a
`GovernanceEnvelope` (tier · reversibility · the FULL effect set — the compile-checked blast radius the
Permission Card shows). Capability gains an OPTIONAL `skills` tuple (wrapped v0 caps omit it → the live
catalog is unaffected), validated for unique names + the I3 tier floor (a skill may only sit at/above
the capability risk). `resolve_skill` + `resolve_skill_verb` are the compiler's lookups: semantic-first,
an explicit `via:` disambiguates, and it REFUSES (never guesses) on an unknown skill or an ambiguous/
unsanctioned via. 14 tests; 87 capability tests green (parser/printer round-trip unaffected).

The frozen L2 contract Hermes emits and the compiler consumes: a BizSpec expresses WHAT must happen in
governed business terms with no runtime detail. Two deliberately-distinct step kinds keep effects and
control flow from blurring (D4): UseStep (call a capability Skill by meaning — Alias.skill, optional
via/bind) and ControlStep (approval/wait/decision/checkpoint/notify — a primitive, never a capability).
The IR checks shape only (dotted Alias.skill, approval needs a strategy, wait needs an event, ≥1 step);
that a `use` names a REAL skill and not a private verb is enforced at COMPILE time by resolve_skill, not
here — an honest boundary. This is the seam that lets Hermes stay replaceable and the compiler stay a
pure L2→L3 function. 8 tests.

…gistry -> CompiledPlan (Wave 4 §14.4b)

The payoff that ties the foundation together: compile_bizspec is a PURE function (same inputs -> same
plan, no model) that lowers a BizSpec through a Domain + the registry. For each skill call it resolves
the alias -> capability via the Domain's imports (D2), pins the exact SemVer at the imported major,
resolves the verb (D3, semantic-first + via), and the backend (D8) — then computes the aggregate
governance envelope (D5: strongest tier respecting the policy floor, union of effects, strongest
reversibility) and validates that the capabilities the plan actually uses form no cycle. Every
unresolved reference is a typed CompileRefusal (I2 — never a guess): UNIMPORTED_ALIAS,
CAPABILITY/MAJOR_NOT_REGISTERED, UNKNOWN_SKILL, UNRESOLVED_VERB, UNBOUND_BACKEND, DEPENDENCY_CYCLE,
DOMAIN_MISMATCH. CompiledPlan is the structured L3 the .nil printer (§14.4c) will serialize. 13 tests;
75 Wave-4 tests green across domain/skill/bizspec/compiler/registry.

…Wave 4 §14.4c pt.1)

render_plan turns a CompiledPlan into stable, human-readable text: the Domain + intent + aggregate
governance envelope, then one line per lowered step (capability@version, skill->verb, governed backend
D8, tier, bind, sorted args). This is the artifact a reviewer confirms before approval and a stable
audit record (same plan -> same text). Explicitly NOT the runnable .nil cycle grammar: lowering a
CompiledPlan to an executable Cycle AST is design-gated — a BizSpec ControlStep is thinner than a
runnable ApprovalStep/WaitForEventStep (no approver/on_approve, match/on_timeout, next-chaining), so the
control-step model must be enriched first (that half of §14.4c starts fresh). 2 tests.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…14.4c pt.2)

Resolves the design gate: L2 carries no runtime scaffolding (§11), so step ids, linear next-chaining,
the Flow entry, and the required transition targets (on_approve/on_reject/on_timeout) are SYNTHESIZED by
the compiler — the BizSpec ControlStep gains only BUSINESS fields (approver, message, match, timeout).
lower_to_flow maps each compiled step to its kernel step type (effect->ActionStep on the resolved verb;
approval/notify/checkpoint/wait->their nodes) and appends a terminal so every target resolves; a
`decision` step is refused in v0.1 (linear plans only). Proven RUNNABLE: a lowered flow wrapped in a
Cycle survives print_nil->parse_nil identically. The full pipeline is now real end-to-end:
BizSpec -> compile -> CompiledPlan -> lower -> runnable .nil. 6 lowering tests; 101 Wave-4 tests green.

… §14.5)

Pulled the ACTUAL cyc_order pipeline from the live control plane and mapped it onto the new stack:
its three effect verbs (resource.read, procurement.create_purchase_invoice, commerce.record_payment)
become a Procurement Domain (D2 imports + D8 odoo bindings) with three Skills, and its linear spine
compiles+lowers cleanly TODAY (resolved verbs, pinned versions, aggregate HIGH/IRREVERSIBLE envelope,
runnable round-tripping .nil). Surfaces the one concrete blocker: step_3's wait `on_timeout→step_5`
escalation is NON-LINEAR, and v0.1 lowering is linear+terminal only. Framed as a design gap (L2 must
stay scaffolding-free per §11) with three options; recommends A (inline business-level `on_timeout`
action, compiler synthesizes the branch). Lays out the 5-step §14.5 plan: close routing gap → author
Domain+Skills → express BizSpec → prove parity → verbs-private.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
… routing gap (Wave 4 §14.5a)

The non-linear branch cyc_order needs, without leaking runtime routing into L2. 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.

…a live production cycle (Wave 4 §14.5b)

The milestone: the live cyc_order (pulled from the control plane) expressed on the new stack — a
Procurement Domain, three capabilities each exposing one Skill, and a BizSpec in business language with
NO step ids and NO routing — compiles+lowers to a flow that reproduces cyc_order's execution semantics:
the same three effect verbs in order (resource.read -> procurement.create_purchase_invoice ->
commerce.record_payment), the same two human gates, and the same mail.received wait with {order_ref:$po}
correlation and the 7-day supplier-silence escalation branch. Governance aggregates to HIGH/IRREVERSIBLE;
backends are now EXPLICITLY bound to odoo (D8 — an improvement over implicit newest-declarer-wins); and
the lowered flow is runnable .nil (print/parse round-trip). Proves the architecture can represent a real
cycle without leaking runtime concepts into the business layer. 6 parity tests. §14.5c (verbs-private)
is now unblocked — only AFTER parity, as ordered.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…erb (Wave 4 §14.5c)

The Skill API becomes the frozen ABI: a cycle reaches an effect ONLY through a Skill, never a verb.
The compiler now refuses a direct verb reference BY NAME (PRIVATE_VERB) instead of a vague "unknown
skill" — "comms.send_email is a private verb of Communication; call it through a skill (send, notify)".
Applied only in the NEW stack (the legacy Cycle model keeps its verbs until the remove-legacy phase, as
ordered: routing gap -> parity -> verbs-private -> delete legacy). Verbs/adapters/ERPs below the Skill
line can now churn without touching any cycle. 1 test; parity + full compiler suite green.
