Summary

Adds a browser-based workspace creation handoff to the CLI: post-scan / altimate-code link opens the Altimate SaaS on <tenant>.ws.myaltimate.com/create-and-link with the current project's context, the user approves in a single modal, and the SaaS delivers the newly-created workspace's id back to a CLI-local loopback listener (same pattern as gateway sign-in). CLI then binds the current project via the existing POST /datamate-project-bindings/bind.

Stacked on the Workspaces draft PR (#1099 / feat/agent-workspaces).

What's added

  • packages/opencode/src/altimate/workspace/browser-handoff.ts (new) — per-flow loopback listener (own instance, walks 7317..7325 past a live OAuth listener), tenant-mismatch guard, typed failure reasons. Duplicates the loopback pattern from altimate.ts deliberately — shared-helper refactor is a follow-up once both flows have prod experience.
  • OfferDialog (post-scan) — adds "Set up in browser (recommended)" as the default option when the deployment supports it (freemium only for pilot; resolveWorkspaceWebUrl returns null otherwise and the option auto-hides).
  • altimate-code link picker — adds "+ Set up in browser" as the first row under the same condition.
  • Dev escape hatchALTIMATE_WORKSPACE_WEB_URL env var overrides the deployment map lookup (used for local integration testing; never set in production).

What's unchanged

Every pre-existing option in the post-scan dialog and altimate-code link picker (Create quick workspace here, Link to an existing workspace, Skip for now, existing workspace-picker rows) continues to work exactly as it does today. The browser-handoff option is strictly additive. Rolling back is a single-commit revert with no schema, no cache format, and no backend-contract implications.

A user whose deployment doesn't support the browser flow (localhost, enterprise) sees zero behavior change — the new option auto-hides.

Tests

  • 14 new unit tests for browser-handoff.ts covering URL resolution edge cases (freemium / localhost / enterprise / malformed), pre-flight failures (unavailable / not-configured), end-to-end via dependency-injected browser opener (happy path, tenant mismatch, cancel via ?error=cancelled, missing workspace_id, invalid workspace_id, browser-open failure with authorizeUrl copyable), and port walk past a squatting listener on 7317.
  • 32/32 workspace + plugin tests pass — no regressions.
  • Typecheck clean.

E2E verified against the live backend

Ran the CLI-side round-trip against a live altimate-backend on localhost:

  • ✅ CLI URL construction with all expected params (client, redirect, state, project_path, project_name, #cli_context)
  • ✅ Loopback listener binds + receives callback
  • ✅ State + tenant validation
  • ✅ Real backend POST /datamates/ creates workspace
  • ✅ Real backend POST /bind links with project_path-based binding (no git remote)
  • ✅ Real backend GET /by-path returns the binding after
  • ✅ Local cache persists to XDG state dir with correct schema
  • ✅ 409-conflict handling on repeated runs is the intended behavior

Full SaaS-side E2E (real browser clicking Approve) is a manual smoke once the paired SaaS PR is up.

Paired SaaS PR

AltimateAI/altimate-frontend PR (feat/AI-8510-workspace-browser-handoff) — stacked on Ralph's feature/AI-8496-ws-list-create branch.

Follow-ups (deliberately out of scope)

  • Loopback-listener extraction into a shared helper (currently duplicated from altimate.ts with a TODO comment).
  • Google-first-time-on-ws. UX (session gate returns user to default post-auth destination instead of /create-and-link; password login works correctly).
  • Enterprise workspace-web-host mapping.
  • Removing the CLI-direct create path (a discussion for after this ships).

Summary by cubic

Adds a browser-based workspace create-and-link flow for CLI and TUI. Previously linking ran only in the CLI; now users approve in the SaaS, the CLI receives a 127.0.0.1 callback, re-verifies credentials, and binds the project. Also adds a persistent “linked” confirmation and a right‑pane sidebar tile.

  • Loopback handoff (new packages/opencode/src/altimate/workspace/browser-handoff.ts): ports 7317–7325 with Host header guard; CSRF state; tenant DNS‑label guard; strictly decimal and Number.isSafeInteger workspace_id; fragment‑only project_remote/project_path; 15‑min unref’d timeout; AbortSignal support with silent return when a newer handoff supersedes an older one; post‑listen error handler; force close of open sockets; typed failures (incl. browser_open_failed with copyable URL); success/cancel via top‑level navigation; returns a credential fingerprint for bind‑time re‑verify.

  • CLI (packages/opencode/src/cli/cmd/link.ts): offers “+ Set up in browser” only when available, unlinked, and pre‑check passes; on success binds, writes a canonical cache key (identifier.projectPath ?? directory), prints the manage URL; maps typed failures; re‑verifies credentials before binding.

  • TUI (packages/opencode/src/plugin/tui/altimate/workspace.tsx): adds “Set up in browser (recommended)” when available; guards credential errors; aborts stale handoffs via a module‑level AbortController and silently ignores superseded results; re‑verifies credentials before bind; replaces success toasts with a persistent linked dialog that can open a safe http(s) manage URL.

  • Sidebar (packages/opencode/src/plugin/tui/altimate/workspace-sidebar.tsx, registered in packages/opencode/src/plugin/tui/altimate/index.ts): read‑only tile shows current workspace and manage URL, marks “(pinned via --workspace)” when applicable, polls every 30s with memoized manage base; gated by the same flag.

  • Local cache (packages/opencode/src/altimate/workspace/state.ts): canonicalizes directory keys via realpathSync on read/write with a one‑shot migration; wraps migration writes in try/catch; best‑effort writes.

  • Availability: resolveWorkspaceWebUrl maps freemium only (api.myaltimate.com → .ws.myaltimate.com), validates tenants, and honors ALTIMATE_WORKSPACE_WEB_URL for dev.

  • Tests (packages/opencode/test/altimate/workspace/browser-handoff.test.ts): cover URL resolution, preflight errors, tenant mismatch, cancel, CSRF state‑mismatch where the legitimate callback wins, fragment handling, port walk, browser‑open failure; isolate ALTIMATE_WORKSPACE_WEB_URL.

  • Rollout

    • Behind Flag.ALTIMATE_WORKSPACE (TUI plugin, sidebar, post‑scan offer, CLI menu).
    • Freemium only; enterprise/local/custom domains hide the browser option.
    • No backend migrations; local cache migration is transparent. Existing CLI link flows remain unchanged.

Written for commit 85161a5. Summary will update on new commits.

📝 Walkthrough

Walkthrough

Adds browser-based workspace creation, credential-scoped local binding state, the link CLI command, and feature-gated TUI workspace setup and sidebar views.

Changes

Workspace linking

Layer / File(s) Summary
Feature gating and registration
packages/opencode/src/plugin/tui/altimate/index.ts
Registers workspace TUI plugins only when Flag.ALTIMATE_WORKSPACE is enabled.
Workspace binding cache
packages/opencode/src/altimate/workspace/state.ts
Adds validated tenant- and API-scoped bindings, canonical directory keys, legacy migration, atomic persistence, and permission handling.
Browser workspace handoff
packages/opencode/src/altimate/workspace/browser-handoff.ts, packages/opencode/test/altimate/workspace/browser-handoff.test.ts
Adds validated loopback callbacks, deployment URL resolution, port fallback, typed outcomes, timeout and abort handling, and coverage for callback and browser failures.
CLI workspace linking
packages/opencode/src/cli/cmd/link.ts
Adds workspace discovery, browser setup, creation, linking, rebinding, conflict recovery, safe management URL handling, and local binding persistence.
TUI workspace flows and sidebar
packages/opencode/src/plugin/tui/altimate/workspace.tsx, packages/opencode/src/plugin/tui/altimate/workspace-sidebar.tsx
Adds browser-handoff setup, credential checks, persistent linking confirmations, cached binding display, management URLs, and post-scan integration.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟡 Moderate · up to a6f59

The browser handoff adds a local callback and browser-managed workspace binding. At the current head, malformed credentials can abort linking, listener failures can terminate the CLI, and path or URL handling can leave linked state or management links incorrect; these bounded correctness and availability issues should be fixed or explicitly accepted before merge.

Poem

I’m a rabbit with a workspace key,
Linking paths from tree to tree.
Browser callbacks hop and land,
Cached bindings stay close at hand.
TUI panels glow with care—
A linked workspace waits there.

Status: 2 Issues Found | Recommendation: Address before merge

Incremental review of 290f43d..7af007c. Note: the base branch (feat/agent-workspaces) advanced and was merged in, so the launch-flag work (launch-resolve.ts, session-context.ts, launch-resolve.test.ts, tui.ts, flag.ts) is now part of the base and outside this PR's commentable diff; the PR-vs-base diff is the 7 browser-handoff/sidebar files. This cycle's earlier fixes — settled listener race, post-listen error handler, preCheckOk gate, tenantKey guard, picker submit latch, placeholder rows, log.warn for dropped diagnostics — verify as resolved.

  • launch-resolve.test.ts:21 (WARNING): the XDG_STATE_HOME sandbox redirect is a no-op — the bunfig test preload freezes Global.Path.state before the test body runs, so cachePath() resolves to the preload dir and the file's isolation works only by accident; also repeats the module-level env-mutation pattern flagged on workspace.test.ts.
  • launch-resolve.ts:45 (SUGGESTION): blank --workspace ("" / whitespace / missing value) is treated as a name and prints a confusing mismatch note.
  • launch-resolve.test.ts:148 (SUGGESTION): the AI-8504 user-facing messages (mismatch note, unlinked-dir error) are never asserted.
  • session-context.ts:8 (SUGGESTION): comment claims consumers run in the TUI worker; the sidebar renders on the main thread.
  • link.ts:377/491 (SUGGESTION): identifier.projectPath ?? directory is a no-op — recordApprovedBinding canonicalizes identically either way; the symlink-divergence comment doesn't hold.
  • workspace.tsx:778 (WARNING): Enter on the "Loading workspaces..." placeholder can race the list swap and fire row 0's action (bindExisting / billable create) — DialogSelect keeps selection at index 0 across the options swap.

This test depends on the machine layout and can fail.

The test asserts that detectProjectRemote(os.tmpdir()) returns undefined. The comment claims /tmp is never a git repository. On CI runners TMPDIR can point inside a checked-out tree, and a parent directory can contain a .git directory. git remote get-url origin then succeeds and the assertion fails.

Point the call at the sandbox directory created at line 16 instead, and confirm the sandbox has no git parent.

Use the tmpdir() fixture and remove the sandbox directory after the run.

Lines 15-17 create a directory under os.tmpdir() and set process.env.XDG_STATE_HOME at module scope. Two problems follow:

  1. The sandbox directory is never removed, so each run leaves a directory behind.
  2. process.env.XDG_STATE_HOME is never restored. bun test can execute several test files in one process, so any other test file that resolves Global.Path.state after this file loads reads the sandbox path.

Set the variable, capture the previous value, and restore it in an afterAll teardown that also removes the directory.

♻️ Proposed teardown
-import { afterEach, beforeEach, describe, expect, test } from "bun:test"
+import { afterAll, afterEach, beforeEach, describe, expect, test } from "bun:test"
 ...
 const SANDBOX = path.join(os.tmpdir(), `altimate-workspace-test-${process.pid}-${Date.now()}`)
 mkdirSync(path.join(SANDBOX, "state"), { recursive: true })
+const PREV_XDG_STATE_HOME = process.env.XDG_STATE_HOME
 process.env.XDG_STATE_HOME = path.join(SANDBOX, "state")
+
+afterAll(() => {
+  if (PREV_XDG_STATE_HOME === undefined) delete process.env.XDG_STATE_HOME
+  else process.env.XDG_STATE_HOME = PREV_XDG_STATE_HOME
+  rmSync(SANDBOX, { recursive: true, force: true })
+})

Based on learnings: "For brand-new test files added under packages/opencode/test/altimate/, follow the documented tracing-test temp-dir convention: import tmpdir from fixture/fixture.ts and use await using tmp = await tmpdir() with per-test scoping." The XDG_STATE_HOME override must be set before the module import, so the fixture may not fit here; the explicit teardown above is the minimum.

As per coding guidelines: "Tests using global mock.module, dispatchers, or similar shared state must provide teardown and isolation safe for parallel bun test execution."

server.close() alone can leave the port bound.

close() stops new connections but waits for open connections to end. The browser normally uses keep-alive on the loopback response, so the socket can stay open and hold the port after the flow settles. Call closeAllConnections() as well, or send Connection: close in respond.

Reject callbacks that do not target the loopback host.

The handler validates state, tenant, and workspace_id, but it does not check the Host header. A remote page that resolves a hostname to 127.0.0.1 can reach this listener. The random state still gates delivery, so exploitation needs the state value. Add a host allowlist for 127.0.0.1 and localhost to close the DNS-rebinding path.

Isolate ALTIMATE_WORKSPACE_WEB_URL in the test setup.

resolveWorkspaceWebUrl reads process.env["ALTIMATE_WORKSPACE_WEB_URL"] on every call and returns the override before any host check.

Add coverage for the CSRF state check and the abort path.

The file header states that the suite covers CSRF state validation, but no test fires a callback with a wrong or missing state. The signal input and the aborted reason also have no coverage. Both paths are security- and lifecycle-relevant. Add a test that fires a callback with a bad state and confirms the flow does not settle, plus a test that aborts through AbortSignal and expects reason: "aborted".

Guard against a detail object without message.

Lines 196 and 203 cast the parsed detail object to ConflictDetail / PreconditionDetail without checking message. If the backend returns an object that omits message, super(detail.message) produces an error whose message is undefined. Callers that render err.message then show an empty string.

Attach a persistent error handler after the listen succeeds.

Line 296 removes onErr once the bind succeeds, so the server has no error listener for the rest of the 15-minute window. A post-bind server error, for example EMFILE on accept, becomes an unhandled error event and terminates the CLI process. Keep a handler that funnels the error into pending.reject.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Guard getCredentials() here.

isConfigured() at line 56 does not prove that the credentials parse. getCredentials() can reject on malformed JSON, a schema mismatch, or an unresolved ${env:…} placeholder; browser-handoff.ts documents the same failure modes at lines 350-354. A rejection at this point aborts the command with an unhandled rejection after prompts.intro and the workspace list already rendered. Treat a failure as "browser handoff unavailable".

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Correct the workspace name in the conflict message.

In the browser flow the SaaS creates the workspace and the user can name it there. projectName is the locally derived auto-name, so the message can state a name that does not exist. Report the workspace ID that the handoff returned instead.

177-186: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Compose the manage URL with URL instead of string concatenation.

resolveWorkspaceWebUrl returns the ALTIMATE_WORKSPACE_WEB_URL override unchanged when it is set. That override can carry a path, query, or fragment. The current concatenation then produces URLs such as https://host/?x=1/w/42. Use the URL constructor with a base so path joining stays correct.

♻️ Proposed refactor
     const base = resolveWorkspaceWebUrl(creds.altimateUrl, creds.altimateInstanceName)
     if (!base) return null
-    return `${base.toString().replace(/\/$/, "")}/w/${workspaceId}`
+    const basePath = base.pathname.endsWith("/") ? base.pathname : `${base.pathname}/`

WARNING: recordApprovedBinding here can reject with no handler, terminating the TUI after a successful bind

createAndBindInline is invoked fire-and-forget (void createAndBindInline(...) at lines 161 and 787), but the post-success await recordApprovedBinding(...) / await showLinkedConfirmation(...) (lines 458-465) sit outside any try. recordApprovedBinding throws when the state dir is read-only/full (Filesystem.writeJsonAtomic) or credentials fail to re-parse. The sibling flows (PickerDialog.pick, bindOrRebindInline) wrap these same awaits in try/catch, and reportFlowFailure was added for the command run() paths — this path was missed. With no global unhandledRejection handler, Bun exits on the rejection, so a cache-write failure after a successful create+bind kills the whole TUI. cli/cmd/link.ts line 345 has the same un-guarded shape (CLI-side, less severe).

WARNING: .catch(() => "") swallows the 15s abort during the body read, misclassifying timeouts as "Empty body" errors

The m8 comment below (and the AbortError branch in the outer catch) promises that an abort fired while reading the body is surfaced as "Request to … timed out after 15s". But res.text() rejects with AbortError when the controller aborts mid-body, and this .catch(() => "") converts that rejection to an empty string before the outer catch ever sees it. A server that sends 200 headers and then stalls now yields WorkspaceApiError("Empty 200 body from … — expected JSON payload") instead of the timeout error, defeating the timeout-vs-network distinction the comment claims. Let body-read errors propagate to the outer catch and only coerce genuinely empty bodies.

SUGGESTION: Deduplicate isSafeHttpUrl (and the manage-URL builders) between workspace.tsx and link.ts

This private helper is byte-for-byte identical to isSafeHttpUrl in cli/cmd/link.ts:368, and buildManageUrl (line 177) is a near-copy of link.ts's manageUrlFor (line 252). Both modules already import from @/altimate/workspace/browser-handoff, so exporting one shared isSafeHttpUrl/manage-URL helper there removes the risk of the copies drifting — e.g. a protocol-hardening fix landing in one file but not the other. Note the doc comment here says "Kept exported as a top-level helper", but the function is not actually exported.

* feat: add Workspaces post-scan prompt + `altimate link` subcommand

Adds the CLI half of the Workspaces pilot: after the first-run scan
completes and the CLI is authenticated with Altimate, prompt the user
once to create a new workspace or attach the project to an existing one.
The link is a direct authenticated call — no device flow — and the
browser opens after create so the user can configure integrations /
knowledge in the SaaS.

Fork-owned TuiPlugin per docs/internal/2026-06-23-tui-fork-features-
as-plugins-adr.md: single file at
`packages/opencode/src/plugin/tui/altimate/workspace.tsx`, added to
the existing `altimateTuiPlugins()` aggregator. Upstream
`packages/tui/**` stays byte-for-byte upstream. Uses the real
`api.ui.*` / `api.keymap.registerLayer` / `api.state.path.directory`
/ `api.kv` (persistent) surface.

Shared modules under `packages/opencode/src/altimate/workspace/` so
the plugin and the `altimate link` subcommand can't drift on request
shape or error handling:

- `api-client.ts` — typed errors (Conflict/Precondition/NotFound/
  Forbidden/NotConfigured/Api), FastAPI `{"detail": {...}}` parsing,
  15s abort timeout, credentials re-read on every call so an account
  switch is picked up without restart.
- `detect.ts` — `detectProjectRemote` + `projectNameFromRemote`;
  reuses `stripGitRemoteCredentials` (now exported from
  `project-scan.ts` so the two callers can't drift).
- `state.ts` — local binding cache scoped to (tenant, apiUrl) with
  atomic write + post-write `chmod 0o600` + corruption recovery.

Trigger: `onboarding-telemetry.ts` `tool.execute.after` hook publishes
`TuiEvent.CommandExecute` with `"altimate.workspace.postScan"` when
`project_scan` completes, gated on the new `Flag.ALTIMATE_WORKSPACE`
and `AltimateApi.isConfigured()` (BYOK users are silently skipped —
no place to send them). Never blocks onboarding on a publish failure.

Server-authoritative pre-check via `GET /datamate-project-bindings/
by-remote`; local cache used only as an offline fallback, and the
fallback path renders a mandatory "unverified" banner rather than
silently trusting stale data. Browser-open failure surfaces a
copyable-URL toast rather than swallowing silently.

7-day Skip latch lives in `api.kv` keyed by SHA-1(remote) — UTC
rolling window; `altimate link` (user-initiated) deliberately
bypasses the latch.

New `altimate-code link` subcommand runs the same three-way flow
outside a TUI session via `@clack/prompts` for scripting / catch-up
after a Skip. Bails early with helpful messages when credentials
are missing or no git remote is set.

Tests: 17 unit tests covering project-name parsing, git detection
graceful failure, cache read/write + chmod + tenant-scoping (account-
switch invalidation), and Skip latch TTL semantics with UTC boundary.

Two user-flagged issues on the Workspaces post-scan prompt landed in
7c7e17f:

1. Post-scan dialog raced the LLM's onboarding-menu streaming — the
   dialog painted while text was still generating, and Enter didn't
   register until streaming finished. Fix: arm a one-shot `session.idle`
   listener via `EventV2Bridge` from `onboarding-telemetry.ts` and
   publish `TuiEvent.CommandExecute` only after the session settles.
   Costs a few seconds of latency; kills the race.

2. `resolveProjectRemote` returned undefined for projects without a git
   remote (materialized sample dbt scaffolds, fresh scratch dirs), so
   the post-scan prompt and `altimate-code link` both bailed silently.
   Fix: new `resolveProjectIdentifier` in `workspace/detect.ts` always
   returns a `{repoRemote?, projectPath}` pair (path is symlink-resolved
   `realpath`). `ProjectIdentifier` type threads through `WorkspaceApi`,
   the TuiPlugin dialogs, and the `link` subcommand — remote is
   preferred when available (stronger identity, survives directory
   moves); path is the fallback the backend indexes symmetrically.

Also: `projectNameFromPath` fallback for auto-naming (derives from
directory basename when no remote); Skip-latch key hashes remote-or-path
so path-only projects also get the 7-day suppression; `runFlow` and
`runOnDemandPicker` reworked to use `WorkspaceApi.getBindingForProject`
(tries remote first, then path); `CachedBinding` in state.ts extended
with `projectPath: string | null`.

Tests updated + one new latch test covers the path-only case. `bun test
test/altimate/plugin/workspace.test.ts` → 18/18.

* fix(workspace): consensus review — flag gating, orphan-safe create, matched-identifier rebind, req() hardening

Addresses the review findings that belong to this PR's commits (7c7e17f
+ 76de5a9). The three remaining findings introduced by the stacked
browser-handoff PR are fixed on that branch.

- Gate the LinkCommand registration in src/index.ts AND the Workspace TUI
  plugin registration behind Flag.ALTIMATE_WORKSPACE. Previously the flag
  gated only the post-scan trigger publish, so the palette command,
  altimate-code link subcommand, and post-scan handler shipped to 100% of
  users regardless of the flag setting. (M1)
- createAndBindInline / createAndBind now accept an "already linked"
  outcome and rebind after create. Before this, "+ Create a new workspace"
  on an already-linked project silently orphaned the freshly-created
  workspace in the SaaS — a real (billable) resource the CLI knew nothing
  about. On rebind failure the error message tells the user the workspace
  exists and how to recover. (M2)
- getBindingForProject now returns which identifier arm matched (remote or
  path) via a new ``matchedBy`` field. AlreadyLinkedDialog, PickerDialog,
  bindOrRebindInline, and cli/cmd/link.ts all use matched-identifier for
  the rebind endpoint — not the CURRENT identifier — so a repo whose
  remote was renamed still repairs via its path binding instead of 404'ing
  on rebindByRemote. hasDrift is now computed from matched-vs-current
  identifier instead of hardcoded false. (M3)
- listDatamates now routes through req() (via a new ``base`` option) so it
  inherits the 15s abort, typed error mapping, empty-body guard, and
  detail parsing every other endpoint gets. Non-integer / non-positive ids
  are filtered out at the boundary. (M5)
- req() throws WorkspaceApiError on an empty 2xx body (previously returned
  undefined as T, producing a downstream TypeError the typed switches
  couldn't classify). ``allowEmptyBody`` opt-in for 204 endpoints. (m7)
- AbortError is now distinguished from a network failure — the 15s abort
  produces "Request timed out after 15s" instead of the generic "Cannot
  reach" message. (m8)
- Session-idle listener now captures the unsubscribe from events.listen()
  and tears itself down when the pending-sessions Set drains. Previously
  the listener was permanently installed for the process lifetime, and a
  failed install could leave a duplicate handler behind that fired
  workspace prompts twice. (m4)
- Failed pre-check in cli/cmd/link.ts now retries a bindExisting → 409 as
  an unconditional rebind, so a user whose pre-check network-flaked isn't
  stuck at "Already linked to X" with no next step. (m10)

* fix(workspace): bot-review round 1 — GitGuardian unblock + null-body guard + safe manage_url open

- Replace token-shaped documentation example in detect.ts with a generic
  <username>/<token> placeholder so GitGuardian's "Basic Auth String"
  detector stops flagging the comment. Not a real credential; the swap is
  cosmetic + pipeline-unblocking. (CR + GitGuardian)
- req() empty-body guard now uses ``== null`` so a literal JSON ``null``
  response (which parses to the JS null, not undefined) is rejected too.
  Previously ``json === undefined`` missed the null case and returned
  ``null as T``, producing a downstream ``TypeError: Cannot read
  properties of null`` that the typed switches couldn't classify. (CR)
- Both open(manage_url) call sites now validate the URL parses as
  http(s) before handing to open(). ``open`` delegates to the OS scheme
  handler, so a rogue server-supplied protocol could launch an unrelated
  application. Extracted a tiny ``isSafeHttpUrl`` helper (duplicated in
  each file — the modules deliberately don't cross-import). (CR)

* fix(workspace): bot-review round 2 — timeout-through-body-read, cache shape validation, listener install race, fire-and-forget catch, test isolation

- Keep the AbortController timeout ACTIVE while ``req()`` reads the response
  body. ``fetch()`` resolves after headers arrive; a server can send headers
  and then stall the body stream forever, and clearing the timer in the
  first ``finally`` broke the 15s cap. Move ``res.text()`` inside the same
  try/finally so both the fetch AND the body read fire the same
  ``AbortError``. (CR)
- ``readCache()`` runs a runtime shape check on the parsed JSON before
  returning — validates version, string tenant/apiUrl, object bindings, and
  each binding's field types. Previously ``{"version":1,"bindings":null}``
  would pass the type assertion and then throw a ``TypeError`` on
  ``cache.bindings[k]``. (CR)
- ``armWorkspacePromptOnSessionIdle`` serializes concurrent install
  attempts via a shared in-flight promise. Previously two concurrent scans
  could both pass the ``!workspacePromptUnsubscribe`` check before either
  install completed, both would install a listener, and the later
  assignment would overwrite the first disposer — leaking the first
  listener for the process lifetime. (CR)
- The keymap ``run()`` callbacks now attach a ``.catch(reportFlowFailure)``
  to the returned promises instead of dropping them with ``void``. An
  unhandled rejection from ``recordApprovedBinding`` / ``readLocalBinding``
  / anything else awaited inside would otherwise terminate the TUI
  process. (CR)
- Test isolation: workspace.test.ts now restores ``XDG_STATE_HOME`` in
  ``afterAll`` and cleans up its SANDBOX tempdir; ``detectProjectRemote``
  test uses a freshly-created empty dir under SANDBOX instead of
  ``os.tmpdir()`` (which can be inside a git worktree, causing the "not a
  git repo" assertion to fail on ``git remote get-url``). (CR)

* fix(workspace): bot-review round 3 — listDatamates shape, teardown Effect, body-read abort, cache best-effort, skip-latch tenant scope

- listDatamates() now accepts three response envelopes — today's
  {datamates: [...]}, a bare array, and a generic {data: [...]} — so a
  backend contract change or compat layer doesn't silently empty the
  workspace picker. Also filters non-string names alongside the existing
  integer/positive id guard. (cubic P1)
- events.listen() returns an Effect, not a callable — the earlier
  teardown cast to (() => void) would have thrown on drain, leaving the
  listener installed. Store the Effect and run it via
  AppRuntime.runPromise on teardown. Also drain EVERY session that
  awaited the shared install promise on install failure, not just the
  one caller — later waiters see success from the promise and stop
  retrying, leaving permanently-stale entries otherwise. (cubic P2)
- req() body-read: dropped the .catch(() => "") wrapper on res.text().
  It swallowed the AbortError from the timeout firing during the body
  read and turned a stalled response into a false "empty body". Any
  read rejection now rethrows into the outer catch and is classified
  there (AbortError → timeout WorkspaceApiError). (cubic P2)
- recordApprovedBinding() is now best-effort: cache-write failures
  (read-only state dir, disk full) are logged and swallowed so the
  caller doesn't report the server-side link as failed and prompt a
  duplicate retry. (cubic P2)
- isValidCacheFile rejects rows with BOTH repoRemote and projectPath
  null/empty — the offline-fallback render path would otherwise present
  a phantom workspace with no identity to verify against. (cubic P2)
- Skip latch key now includes (tenant, apiUrl) scope, matching the
  local binding cache. Otherwise a Skip in one Altimate account
  suppresses the post-scan prompt for the same project in every other
  account for 7 days. Scope is resolved once by runFlow (currentLatchScope)
  and threaded into OfferDialog so its sync onSelect can call recordSkip
  without a mid-render await. (cubic P3)
- projectNameFromRemote handles foo.git/ (trailing slash after .git) —
  earlier .git$ → /$ pipeline missed it because the final / wasn't .git
  any more. (cubic P2)
- Test isolation follow-up: use GIT_CEILING_DIRECTORIES in the
  detectProjectRemote test so git can't walk up out of SANDBOX and
  return an ancestor repo's remote. New cross-tenant Skip-latch test.

* fix(workspace): bot-review round 4 — Array.isArray guard on listDatamates envelope fields

If ``/datamates`` returns ``{datamates: <non-array>}`` or ``{data:
<non-array>}`` (object, string, null — e.g. from a legacy proxy or a
schema mismatch), the round-3 unguarded assignment would let a non-array
reach ``.map`` and crash the picker before it rendered. ``Array.isArray``
on each envelope field falls back to ``[]`` instead. (cubic round 4.)

* fix(workspace): bot-review round 5 — pre-map null-row guard, contain fire-and-forget rejection

Two cycle-5 findings on files shared with #1100:

- **api-client.ts listDatamates** (Kilo warning) — a single ``null`` element
  in an otherwise-valid rows array threw ``TypeError`` on ``d.id`` before
  the post-map filter could drop it. That's the exact picker-down failure
  the round-3/4 envelope guards were added to prevent, just per-element.
  Filter valid row objects BEFORE the map.
- **workspace.tsx createAndBindInline** (Kilo warning) — the post-success
  tail (``recordApprovedBinding`` + ``open()`` + toasts) sat outside any
  try inside a fire-and-forget entry point. An unhandled rejection could
  take the TUI down. Contain the tail in a try/catch that falls back to a
  plain info toast so the user still sees the URL.

Test suite green (33 pass in workspace suites, no regressions in the wider
altimate test set).

* fix(workspace): bot-review round 6 — flag opt-in, skip clock rewind, cred guard, canonical cache key, placeholder rows, 409-fallback endpoint

Six correctness fixes landed on the branch; a seventh finding (already-linked
"Create new" → orphaned workspace) is documented as deferred because a
CLI-only fix isn't possible without a new backend endpoint.

- **``ALTIMATE_WORKSPACE`` opt-in only** (Kilo warning) — was routed through
  ``enabledByExperimental`` and silently inherited ``OPENCODE_EXPERIMENTAL``.
  Users opted into other experimental features were getting the Workspaces
  pilot turned on for them, contradicting the "off by default" rollout.
  Swap to bare ``truthy("ALTIMATE_WORKSPACE")``.
- **Skip latch rejects future timestamps** (CodeRabbit minor) — a clock
  rewind after ``recordSkip`` would produce ``nowMs - skippedAt < 0``,
  trivially under the 7-day TTL, and suppress the prompt indefinitely.
  Treat future timestamps as corrupt and re-offer on the next scan.
- **``tenantKey`` guards ``getCredentials``** (Kilo warning) — the helper
  can throw ``SyntaxError`` / ``ZodError`` / raw ``Error`` on corrupt or
  drifted credentials; those were escaping the "best effort" contract of
  the state module and terminating fire-and-forget callers. Wrap in
  try/catch and log-warn.
- **``link.ts`` cache key uses canonical identifier** (Kilo warning) — was
  ``recordApprovedBinding(args.directory, ...)`` which stored under the
  raw --directory arg; ``altimate-code link -d ./myproj`` and its
  symlink-resolved twin produced two separate cache rows. Prefer
  ``identifier.projectPath`` (canonicalized by ``resolveProjectIdentifier``).
- **Placeholder rows no longer filtered** (Kilo warning) — ``DialogSelect``
  drops ``disabled: true`` options, so the "Loading workspaces..." and
  "No workspaces yet..." rows never rendered and the picker showed an
  empty list. Remove ``disabled: true``; the ``value === -1`` guard in
  ``onSelect`` already closes the dialog on selection.
- **409-fallback rebind picks endpoint from conflict detail** (Kilo warning)
  — was keying off the current project identifier, reproducing the M3
  hazard: a path-keyed legacy binding hit ``rebindByRemote`` and 404'd.
  Derive the endpoint from ``err.detail.project_path`` / ``err.detail.repo_remote``
  which the server sends for exactly this purpose.

**Deferred to follow-up ticket:**
- chatgpt-codex P1 "Create new workspace when already-linked → orphan"
  needs either a new backend endpoint that creates without binding, or a
  CLI refactor that calls the plain ``POST /datamates/`` route + rebind.
  Both are more than a bot-review-cycle fix. Noting so the ticket can be
  scheduled explicitly.

Test suite: green (4058 pass, 0 fail across the altimate suite).

* fix(workspace): bot-review round 7 — canonical cache key, picker submit-guard, dead-param removal, non-TTY guard

Five focused fixes from bot triage against #1099, verified against the
current tip (`7207840e69`); earlier rounds (4/5/6) landed everything
else. All 4058 altimate tests pass.

- **state.ts** `canonicalDirKey` normalizes directory keys via
  `path.resolve` + `realpathSync` so `/tmp/foo`, `/private/tmp/foo`
  (macOS symlink), `/tmp/foo/`, and relative paths hit one row. Two
  clients pointing at the same project via different path spellings no
  longer see split cache rows. Falls back to resolved-only when the
  path doesn't exist yet. (cubic + kilo cycle 6.)
- **workspace.tsx `PickerDialog`** adds a `submitting` latch inside
  `pick()`. `DialogSelect` delivers `onSelect` synchronously per
  Enter, and a second Enter before the network call resolved would
  fire a duplicate bind whose 409 toast then contradicts the first
  call's success toast. (kilo cycle 6.)
- **workspace.tsx conflict-toast copy** used to say *"pick Re-link
  from the offer"* but `OfferDialog` has no Re-link row — a dead
  referral in the middle of a user's first bad experience. Points at
  the actual next action (`altimate-code link`) instead. (kilo cycle 6.)
- **workspace.tsx `suppressLatch` removed** everywhere. `runFlow`
  never gets called with `suppressLatch: true` — the palette command
  `altimate.workspace.link` uses `runOnDemandPicker`, not `runFlow` —
  so the whole prop chain (interface field, ternary description, guard
  around `recordSkip`, `runFlow` opts, two threading sites into
  `OfferDialog`) was dead code. (kilo cycle 6.)
- **link.ts non-TTY fail-fast** at handler top: `!process.stdin.isTTY`
  → error out immediately with a clear message pointing to the TUI
  palette alternative. Piped or redirected stdin (CI runner,
  background job, `< /dev/null`) would otherwise hang forever on the
  first `prompts.select` with no output. (kilo cycle 6.)

* feat(workspace): --workspace <name> launch flag (AI-8504 item 1)

Add a top-level `--workspace <name>` yargs option to `altimate-code`
that pins the session to the workspace this directory is linked to,
by name. Groundwork for AI-8397 / AI-8434 (memory RW to mem0 scoped
to Workspace), where the resolved workspace id becomes the input to
"which workspace am I in?" lookups.

**Files:**

- `altimate/workspace/session-context.ts` — env-var handoff so the
  main-thread resolver's result reaches the TUI worker subprocess.
  Same mechanism `ALTIMATE_LAUNCH_ID` uses (the existing worker-spawn
  `env: { ...process.env, ... }` spread in `cli/cmd/tui.ts` carries
  the resolved workspace id across for free). Guards against a
  malformed env-var value poisoning callers with NaN.
- `altimate/workspace/launch-resolve.ts` — the resolver.
  `nameMatches(name, binding)` is case-insensitive + whitespace-trimmed,
  exact match only, no fuzzy match, no backend name search
  (same-directory-only per the AI-8504 spec and Path A reference on
  `feature/workspace-link-onboarding`). Missing binding → prints an
  error and returns without setting the env var. Wrong name against
  an existing binding → prints a note and attaches to the linked
  workspace anyway (ticket's explicit choice: "print a note and
  continue with the currently-linked one"). The flag is gated on
  `Flag.ALTIMATE_WORKSPACE` so it's invisible to non-pilot users.
- `cli/cmd/tui.ts` — adds the yargs option and calls the resolver
  after `cwd` is resolved but before `new Worker(...)`. Wrapped in a
  try/catch that logs and continues so a resolver failure can never
  block launch.
- `test/altimate/workspace/launch-resolve.test.ts` — 13 unit tests
  covering `nameMatches` (exact / case / whitespace / mismatch /
  substring), `resolveWorkspaceForLaunch` (no arg, flag off, matching
  name, case-insensitive match, mismatch-still-attaches, unlinked
  dir), and the session-context env-var round trip (set/get/clear,
  malformed value returns null).

**Manual smoke:**

Rebuilt binary, seeded a test binding, ran end-to-end against a
temp directory: matching name prints `Attached to workspace "Growth"`,
wrong name prints the note + attaches to the linked workspace,
unlinked dir errors cleanly, and `ALTIMATE_WORKSPACE=0` makes the
flag silent-no-op. All observed as designed.

**No consumer on #1099** — the sidebar tile that reads "current
workspace" lives on the #1100 branch. This PR ships the flag +
resolver + env-var infrastructure; a follow-up commit on #1100
wires the sidebar to prefer `getResolvedWorkspaceId()` over its
current on-disk binding read.

**Drift resolver (AI-8504 item 2) is NOT included** — it needs a
backend PATCH-binding endpoint that doesn't exist yet, plus a
conflict-of-interest to think through with the post-scan drift
prompt already shipped in `workspace.tsx`. Tracked separately.

* fix(workspace): satisfy Marker Guard — insert --workspace option BEFORE --agent

Marker Guard failed on b193a5c because the --workspace option
was chained AFTER .option("agent"), which required moving the
upstream trailing comma. Marker Guard flagged the modified upstream
line as "new code without marker" even though a marker was
placed above it.

Fix: insert .option("workspace") BEFORE .option("agent") in the
yargs chain so the upstream .option("agent") closer stays byte-for-
byte unchanged. Wrap the new option in a paired altimate_change
start/end marker.

Behaviour-free — same set of options with the same behavior; just
different insertion point in the builder chain.

* docs(workspace): address altimate-harness-bot review — cross-refs + SessionEvent.Idle NOTE

Three trivial doc additions from bot review (altimate-code #1099):

1. `isSafeHttpUrl` in link.ts now points to its verbatim copy in
   workspace.tsx ("keep in sync when the allowed-protocol set changes").
2. `rebindByMatchedIdentifier` in link.ts now points to its verbatim copy
   in workspace.tsx ("keep in sync when the M3 endpoint-selection logic
   changes").
3. Added an inline NOTE at the `event.type !== SessionEvent.Idle.type`
   check explaining that `SessionEvent` here is the module-local alias
   for the MODERN `Event` (EventV2.define), not the deprecated
   `LegacyEvent.Idle`. Bots have flagged this token as "deprecated"
   twice in review; defusing it in-source so it doesn't come up again.

* fix(workspace): address harness-bot round 8 — Event.Status + clear() on install fail

Two findings on packages/opencode/src/altimate/plugin/onboarding-telemetry.ts:

1. Subscribe to Event.Status with status.type === "idle" instead of the
   deprecated Event.Idle. session/status.ts:49 marks Event.Idle as
   `// deprecated`; the non-deprecated path is Event.Status filtered on the
   idle status shape (matching what session/status.ts:176 uses for the
   legacy Bus SSE mirror). Replaces the earlier NOTE that only asserted
   "not the deprecated LegacyEvent" — the NOTE was technically correct but
   deflected from the fact that Event.Idle itself is deprecated too.
   (altimate-harness-bot #1099 comment 3837907427.)

2. Drain the pending set with pendingWorkspacePromptSessions.clear() on
   install failure instead of iterating an install-time snapshot. A second
   scan calling armWorkspacePromptOnSessionIdle after the snapshot but
   before the install fails would otherwise leave its sessionID as a
   permanent orphan in the pending set — no listener would ever fire for
   it, so its post-scan workspace prompt would silently never arm.
   (altimate-harness-bot #1099 comment 3837907105, P2.)

Adds a browser handoff for creating and linking a Workspace: CLI opens the
SaaS approval modal on `<tenant>.ws.myaltimate.com/create-and-link` with the
current project's context (git remote or path + auto-derived name), user
approves, the SaaS creates a workspace and delivers its ID back to the CLI
via a loopback callback (same pattern as gateway sign-in). CLI then binds
the current project to that workspace via the existing `POST /bind`.

Additive to `feat/agent-workspaces` — every pre-existing option in the
post-scan dialog and `altimate-code link` picker (Create quick workspace,
Link to existing, Skip, workspace-picker rows) continues to work unchanged.
The new "Set up in browser" option auto-hides when the deployment isn't
supported (localhost, enterprise, custom domain) — freemium only for pilot.

- New `packages/opencode/src/altimate/workspace/browser-handoff.ts`:
  loopback listener (own instance per flow, port walk 7317..7325 with
  natural fallback past a live OAuth listener), tenant-mismatch guard,
  typed failure reasons. Duplicates the loopback pattern from
  `altimate.ts` deliberately — shared-helper refactor is a follow-up
  ticket once both flows have prod experience.
- Post-scan `OfferDialog`: adds "Set up in browser (recommended)" as the
  default when available, sitting alongside the existing options.
- `altimate-code link` picker: adds "+ Set up in browser" as the first
  row when available.
- Handles browser-open failures with a copy-URL fallback; 15-min timeout;
  explicit cancel via SaaS-delivered `?error=cancelled`.

Tests: 14 new unit tests for browser-handoff (URL resolution, pre-flight
failures, end-to-end via dependency-injected browser opener, port walk
past a squatting listener). 32/32 workspace + plugin tests pass.
…r tile

- Deliver workspace handoff to CLI loopback via top-level navigation (matches
  OAuth sign-in pattern), bypassing HTTPS→loopback Private Network Access
  restrictions that would gate a subresource fetch in prod. Cancel uses the
  same mechanism; loopback bounces the browser back to the SaaS workspace
  page on success and workspace home on cancel.
- Replace transient success toasts with a persistent post-bind
  `WorkspaceLinkedDialog` (workspace name + manage URL + "Continue editing
  in browser" / "Done"). Wired into all five bind success paths (browser
  handoff, inline create, picker attach, picker rebind, on-demand palette).
- New right-pane sidebar tile showing the currently-linked workspace + manage
  URL, polling the local cache every 3s so a fresh bind surfaces without a
  TUI reload. Falls back to "Not linked — run /link" for unbound projects.
- Canonicalize local binding cache keys via `realpathSync` on both write and
  read paths, with a scan fallback for pre-existing entries. Fixes the macOS
  `/tmp` → `/private/tmp` symlink mismatch that caused the sidebar and
  by-path lookups to miss bindings the CLI itself had written.
- `altimate-code link` subcommand: show manage URL on success, cancel via
  top-level nav for reliability.

… re-verify, sidebar polish, cache canonicalization

Addresses the review findings introduced by this PR's commits (browser
handoff + top-level nav / sidebar tile). PR #1099 fixes landed
separately.

- `runHandoffWithOpener` now wraps preflight (`getCredentials`) AND the
  post-listener async IIFE in one try/catch that converts every error to
  a `HandoffResult`. Previously a malformed credentials file rejected the
  returned Promise with no toast, and a throw inside the lazy
  `import("../plugin/altimate")` left the caller waiting the full 15
  minutes with no reason surfaced. The port is captured into a local
  immediately after `startListener` resolves so a timeout-cleared handle
  can't be dereferenced later. (M4)
- `HandoffSuccess` now carries a `credentials` fingerprint (apiUrl +
  tenant) that the handoff was validated against. `runBrowserHandoff` in
  both entry points re-reads `AltimateApi.getCredentials()` immediately
  before `bindExisting` and refuses if either field drifted — workspace
  ids are tenant-schema-local so a mid-flow account switch would
  otherwise bind under the wrong tenant. (M6)
- `resolveWorkspaceWebUrl` guards the tenant with a DNS-label regex and
  reconstructs the origin from the parsed URL, so a credential row
  carrying `evil.example/path?x=` cannot open the handoff at
  `https://evil.example`. Override still available for local dev; both
  paths reject non-http(s) protocols. (m3)
- Optional `AbortSignal` on `OpenBrowserHandoffInput` — a caller-fired
  abort tears down the listener immediately with `reason: "aborted"`
  instead of holding the port for 15 minutes; timeout is `.unref()`'d so
  it doesn't keep the CLI process alive on its own. (m2)
- `port_exhausted` is now only returned when the errno is `EADDRINUSE`
  — other codes (EACCES, EBADF) map to `reason: "error"` so the user
  isn't told "ports all in use" for a permissions problem. (m5)
- `project_path` + `project_remote` moved to the URL fragment, matching
  the `cli_context` rationale — those two values carry usernames /
  customer names / internal paths that shouldn't land in SaaS access
  logs, WAF logs, or browser history. `project_name` stays in the query
  because the SaaS approval modal renders it. Test updated. (m6)
- `workspace_id` uses `Number.isInteger` instead of `Number.isFinite`,
  so `42.5` no longer reaches a backend expecting an integer. (m9)
- Inline `<script>` blocks now escape `</script` in JSON.stringify'd
  values via a `<\/script` replacement, closing the theoretical inline-
  script-break vector. (N5.b)
- Local binding cache: one-shot migration to canonical keys on the
  first `readLocalBinding` that finds a non-canonical key, followed by
  a plain property lookup for every subsequent read. Deletes the O(n)
  `realpathSync` rescan that ran on every cache miss under the 3s
  sidebar poll. (N1)
- Sidebar tile polls at 30s instead of 3s, memoizes the manage-URL
  base per (apiUrl, tenant), and guards against overlapping refreshes.
  Copy updated from "run /link" (the slash command doesn't exist —
  N2) to "run altimate-code link" (the actual CLI subcommand).
  Interval timer `.unref()`'d.

…inked project, tighter workspace_id spelling

Two #1100-only cycle-5 findings:

- **link.ts SET_UP_IN_BROWSER_SENTINEL** (CodeRabbit Major) — the browser
  handoff option was offered even when the project was already linked;
  ``runBrowserHandoff`` then created a fresh workspace and 409'd on
  ``bindExisting``, stranding the workspace. Gate the option on ``!existing``
  alongside ``browserAvailable``.
- **browser-handoff.ts workspace_id** (cubic P3) — ``Number()`` coerces
  ``"1e2"``, ``"0x2a"``, and ``"  42 "`` into finite integers, slipping past
  the ``isInteger`` guard. Require a plain decimal-digit spelling first.

Test suite green (4072 pass across the altimate suite).

… gate on preCheckOk, keep err diagnostic

Three #1100-only cycle-6 findings:

- **``isBrowserHandoffAvailable`` guarded** (CR Major) — line 63 wrapped
  ``isConfigured()`` with ``.catch(() => false)`` but ``getCredentials()``
  on line 64 was unguarded. That call can throw on corrupt credentials JSON,
  Zod schema drift, or an unresolved ``${env:...}`` reference; an unhandled
  rejection there would take the TUI down. Wrap the whole body in try/catch
  and fail closed (treat as "handoff unavailable").
- **``link.ts`` browser option also gated on ``preCheckOk``** (Kilo suggestion)
  — was ``browserAvailable && !existing``. When the pre-check itself failed
  (network / 5xx), ``existing`` stays null while the project MAY be linked
  server-side. Offering the browser flow then reproduces the "workspace
  created + 409 on bindExisting" strand. Add ``&& preCheckOk``.
- **``void err`` no-op replaced with log** (Kilo suggestion) — the previous
  ``catch (err) { ... void err }`` discarded the diagnostic. Log-warn so a
  regression in ``showLinkedConfirmation`` doesn't vanish silently.

Test suite: green (4072 pass, 0 fail).

…ing-abort race

Two focused fixes on browser-handoff.ts. Both verified against the
current tip after rebase onto the updated #1099 branch. Full altimate
suite (4072 tests) passes.

- **Persistent post-listen server error handler.** ``startListener``
  attached an ``onErr`` handler only for the ``server.listen()``
  port-walk (via ``once("error", …)``, removed on the ``listen``
  callback). After a successful bind the server had NO error handler
  for the ~15-minute wait window, so any post-listen socket-level
  ``error`` event (spurious ECONNRESET, client-abort mid-request,
  transient EMFILE) reached the process as an unhandled exception and
  terminated the CLI. Attach a persistent log-and-continue handler
  right before returning ``{server, port}`` — the listener is per-flow
  and there is nothing useful to do with a transient socket error but
  keep serving until the caller resolves or the timeout fires.
  (CodeRabbit cycle 6.)

- **Listener leak when the flow settles during ``await
  startListener(pending)``.** ``closeListener`` closes
  ``listenerHandle.server`` only when the handle is non-nullish, and
  ``listenerHandle`` is assigned AFTER ``await startListener(...)``
  returns. If the flow rejects during that window (timeout raced with
  the port walk, ``AbortSignal`` fired, or the lazy ``buildCliContext
  import()`` threw), ``closeListener`` ran with a still-undefined
  handle — a no-op — and the awaited startListener eventually returned
  a bound server that stayed open for the full 15-minute timeout.
  Introduce a ``settled`` flag flipped by ``pending.resolve`` /
  ``pending.reject``; check it immediately after
  ``listenerHandle = await startListener(pending)`` and close the
  server if the flow already settled. (cubic cycle 5.)

Other #1100-tagged findings verified as fixed at tip in earlier rounds
(preCheckOk gate, isBrowserHandoffAvailable cred guard, Number()
coercion tightening, .git/ trailing strip, SSH ``git@host:path``
credential no-op, writeCache best-effort try/catch) and are not
re-touched here.

… was launched with the flag

The `--workspace <name>` launch flag (AI-8504 item 1, landed on #1099
as b193a5c) sets `ALTIMATE_RESOLVED_WORKSPACE_ID` for the worker
subprocess to read. The sidebar tile already shows the correct
workspace name because launch-time resolution is same-directory-only
and always matches the on-disk binding — so the ID from
`getResolvedWorkspaceId()` == `binding.datamateId` whenever the flag
took effect. Surface that as a small visual confirmation so the user
knows the flag was recognized rather than silently ignored.

Renders as `<workspace-name> (pinned via --workspace)` when the ID
matches, else just `<workspace-name>` (behaviour unchanged for
default launches).

… wins over rogue

Adds coverage for the state check (`pending.state !== state`) which is
the primary guard against a local rogue process (another browser tab, a
compromised npm script, a VSCode extension) forging a callback with an
attacker-chosen workspace id.

Test fires a wrong-state callback first (with workspace_id=999) then a
correct-state callback (workspace_id=1); asserts the result resolves
with 1 and not 999. Confirms two things:

- The wrong-state hit is rejected without resolving the pending promise
  (returns 400 to the client, listener keeps waiting).
- The listener is still alive to accept the follow-up legitimate
  callback, i.e. one bad attempt doesn't kill the flow.

15/15 browser-handoff tests pass (was 14 — this one is the +1).

…ets, pin marker semantics

Three findings on the browser-handoff + sidebar surfaces:

1. DNS-rebinding guard on the callback listener. Binding to 127.0.0.1 is
   necessary but not sufficient: a malicious page whose hostname resolves
   to 127.0.0.1 can drive the browser to attacker.com:7317/workspace-bound
   and the socket lands on our listener with Host: attacker.com. State
   validation catches it eventually, but rejecting the request on Host
   mismatch kills the attack before touching state.
   (altimate-harness-bot #1100 comment 3837907679.)

2. server.close() leaves keep-alive sockets open. Follow every close()
   with server.closeAllConnections?.() (Node 18.2+, safe with the
   optional-call guard).
   (altimate-harness-bot #1100 comment 3837907954.)

3. Sidebar `(pinned via --workspace)` label — clarified semantics with a
   code comment (option b of the review). Known imprecision is accepted;
   getResolvedWorkspaceId() already encodes "was passed AND resolved" at
   the env-var level, so the pin never falsely appears for a session that
   wasn't launched with --workspace.
   (altimate-harness-bot #1100 comment 3837908331.)

Pass an AbortSignal so a superseded handoff releases its port.

openWorkspaceBrowserHandoff accepts an optional signal, and browser-handoff.ts documents it as the way for a TUI to "supersede a stale handoff without leaking a port for the full 15-minute window". This call omits it. If the user starts the browser flow, abandons it, and starts it again, the first loopback listener stays bound for 15 minutes and the second flow walks to the next port. Hold a module-level AbortController for the active handoff, abort it when a new handoff starts, and pass its signal here.

Isolate ALTIMATE_WORKSPACE_WEB_URL in these tests.

resolveWorkspaceWebUrl returns the override URL when ALTIMATE_WORKSPACE_WEB_URL is set, before the freemium host check runs. The PR documents that developers set this variable for local testing. If it is set in the shell or CI environment, every assertion in this describe block fails, and the end-to-end tests also target the override origin. Delete the variable in a beforeEach and restore it afterwards.

SUGGESTION: Number() + Number.isInteger accepts workspace IDs beyond Number.MAX_SAFE_INTEGER, silently rounding them

The decimal-digit regex rejects non-canonical spellings ("1e2", "0x2a", " 42 "), but it does not reject oversized values. Number("9007199254740993") rounds to 9007199254740992, which is still an integer and passes the guard on the next line, so the CLI would bind to a different workspace than the SaaS created. Effectively unreachable today (auto-increment IDs stay far below 2^53), but Number.isSafeInteger is a one-word hardening that closes the gap.

SUGGESTION: Migration writes the cache on the read path without best-effort error handling

migrateToCanonicalKeys runs during readLocalBinding and calls writeCache(next) directly. writeCache's Filesystem.writeJsonAtomic (line 122) is not wrapped, so a failing write (read-only state dir, full disk, EACCES) throws out of readLocalBinding — unlike recordApprovedBinding, which wraps its write in try/catch as "best-effort UX convenience, not the source of truth". In the offline fallback path (workspace.tsx runFlowreadLocalBinding) this surfaces as a spurious "Workspace setup failed" toast even though the binding is perfectly readable. Wrap the migration write in try/catch (or defer it to the next recordApprovedBinding) so the read path stays best-effort.

Fixed in d011067f — wrapped the writeCache(next) inside migrateToCanonicalKeys in try/catch. The migrated shape is still returned in-memory for the current readLocalBinding call; the next successful recordApprovedBinding persists the canonical form. A read-only state dir no longer surfaces "Workspace setup failed" on the offline-fallback path.

… migrate wrap, test isolation

Five findings on #1100:

1. link.ts:257 — Browser-flow recordApprovedBinding now caches under
   `identifier.projectPath ?? directory`, matching the other two call
   sites (lines 377 and 496). Otherwise `altimate-code link -d ./myproj`
   writes under a different key than the canonical form and the TUI
   sidebar can miss it. (coderabbitai #1100 comment 3841173342.)

2. workspace.tsx runBrowserHandoff — Module-level AbortController for
   the active handoff, aborted + replaced when a new one starts. Without
   this, an abandoned handoff kept its loopback listener bound for the
   full 15-minute callback window. Threaded through as the `signal` arg
   openWorkspaceBrowserHandoff already accepts. (coderabbitai #1100
   review 5005112438.)

3. browser-handoff.test.ts — `isolateWebUrlOverride()` helper wired
   into all three describes (resolveWorkspaceWebUrl,
   runHandoffWithOpener end-to-end, port walk). Saves/restores
   ALTIMATE_WORKSPACE_WEB_URL around every test so a shell or CI env
   with the override set can't silently break the assertions.
   (coderabbitai #1100 review 5005112438.)

4. browser-handoff.ts:285 — Number.isSafeInteger, not isInteger. A
   workspace_id above 2^53 would round on `Number(...)` and still pass
   the isInteger guard, so the CLI could bind to a different workspace
   than the SaaS created. Unreachable today (auto-increment IDs stay
   well below the safe range) but a one-word hardening. (kilo-code-bot
   #1100 comment 3841208550.)

5. state.ts migrateToCanonicalKeys — Wrap the migration writeCache in
   try/catch. Without it, a read-only state dir or full disk raised a
   spurious "Workspace setup failed" toast from the offline-fallback
   readLocalBinding path, even though the binding was perfectly
   readable. The migrated shape is still returned in-memory; the next
   successful recordApprovedBinding persists the canonical form.

SUGGESTION: Superseding a still-open handoff surfaces a spurious "Handoff aborted" error toast

When a second handoff supersedes the first via activeHandoffAbort.abort(), the superseded openWorkspaceBrowserHandoff settles with { ok: false, reason: "aborted", message: "Handoff aborted" }. That result flows into toastHandoffFailure, which has no case "aborted" and falls through to default, emitting an error toast ("Handoff aborted") to a user who simply re-triggered setup — alongside the new flow's "Opening browser..." info toast.

Consider returning early when result.reason === "aborted" (or handling aborted as a silent/info case in toastHandoffFailure) so a superseded flow doesn't report a failure the user never caused.

Fixed in 85161a58 — early-return in runBrowserHandoff when result.reason === "aborted". The newer flow's "Opening browser..." toast is the correct signal; the superseded promise exits silently instead of hitting toastHandoffFailure's default red toast. Regression from my own AbortController fix — thanks for catching.

…e toast

The AbortController-supersede fix in d011067 introduced a regression: a
handoff aborted via ``activeHandoffAbort.abort()`` (fired when the user
re-triggers the flow) settles as ``{ ok: false, reason: "aborted" }``.
That flowed through ``toastHandoffFailure``, which has no ``case
"aborted"`` and hit the ``default`` — surfacing a red "Handoff aborted"
error to a user who just re-triggered setup, on top of the new flow's
"Opening browser..." info toast.

Early-return in ``runBrowserHandoff`` when ``result.reason === "aborted"``
so a superseded flow exits silently. The newer handoff's own toasts
carry the real UX. (kilo-code-bot #1100 comment 3841282737.)
