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-creation handoff across CLI/TUI to reduce setup friction. Previously create/link ran only in-CLI; now post-scan and altimate-code link open a SaaS modal, approve via top-level navigation, loop back to a local listener, re‑verify credentials, bind by repo remote or canonicalized path, and confirm.

  • Loopback listener on 127.0.0.1 (ports 7317–7325) with 15‑min timeout, caller abort, cancel handling, and copyable‑URL fallback. Validates origin/protocol, DNS‑label tenant, and strictly‑decimal workspace_id; moves project_remote and project_path to the URL fragment.
  • Resolves workspace web URL to http(s) freemium hosts only; hides the browser option on unsupported deployments and when the project is already linked.
  • Re‑reads AltimateApi credentials immediately before bind and refuses on drift; API client adds typed errors, timeout through body read, empty/null‑body guard, and flexible list envelopes; manage URL opens only for http(s).
  • TUI: OfferDialog adds “Set up in browser”; persistent WorkspaceLinkedDialog after bind; right‑pane sidebar tile shows the current workspace and manage link, polls every 30s, and reads a per‑tenant+apiUrl local cache with canonical‑key migration.
  • CLI: new altimate link subcommand shares API/state/detect modules; orphan‑safe create with auto‑rebind; matched‑identifier rebind; retries bind→409 as rebind; validates and opens the manage URL.

Rollout

  • Behind Flag.ALTIMATE_WORKSPACE; plugin and CLI command registration are gated.
  • Freemium deployments only; enterprise/local/custom domains hide the browser option.
  • For local testing, set ALTIMATE_WORKSPACE_WEB_URL to a ws. host under your environment.

Written for commit 290f43d. Summary will update on new commits.

Haider and others added 2 commits August 12, 2026 23:06
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.

…prompt

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.

Merge Risk: 🟡 Moderate · up to 290f4

This PR adds a browser-based workspace creation path and related binding cache behavior. At the current head, unresolved failure-path and concurrency defects can abort the CLI, leak a loopback port, crash after binding, or lose a cached project binding; credential and URL edge cases can also break supported flows. The PR should not merge until these bounded issues are fixed or explicitly accepted.

A rabbit links a workspace bright,
Through browser hops and cache-tight night.
The TUI shows projects grow,
While idle scans prompt below.
Bind, browse, and save with care—
A workspace blooms in every lair.

…atched-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)

packages/opencode/src/altimate/workspace/api-client.ts 172 .catch(() => "") on res.text() swallows the 15s AbortError during the body read, so a mid-body timeout on a 2xx is misclassified as "Empty 200 body" instead of the promised timeout error

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")

+  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.

🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy lift

Serialize the read-modify-write cycle on the cache file.

recordApprovedBinding reads the whole cache, mutates one key, and writes the whole file. migrateToCanonicalKeys (called from readLocalBinding, lines 137-139) does the same on the read path. Filesystem.writeJsonAtomic makes each write atomic, but it does not make the read-modify-write sequence atomic. Two overlapping callers therefore lose an entry.

This is reachable in this PR: the sidebar refresh in packages/opencode/src/plugin/tui/altimate/workspace-sidebar.tsx calls readLocalBinding while the TUI or altimate-code link flow calls recordApprovedBinding. A migration write started from the read path can overwrite a binding that was just recorded.

Add an in-process mutation queue and re-read the cache inside the critical section.

🔒️ Proposed serialization
+let mutationChain: Promise<unknown> = Promise.resolve()
+
+function withCacheLock<T>(fn: () => T | Promise<T>): Promise<T> {
+  const next = mutationChain.then(fn, fn)
+  mutationChain = next.catch(() => {})
+  return next
+}
+
 export async function recordApprovedBinding(
   directory: string,
   binding: CachedBinding,
 ): Promise<void> {
   const key = await tenantKey()
   if (!key) return
-  const existing = readCache()
-  const cache: CacheFile =
-    existing && existing.tenant === key.tenant && existing.apiUrl === key.apiUrl
-      ? existing
-      : { version: CACHE_VERSION, tenant: key.tenant, apiUrl: key.apiUrl, bindings: {} }
-  cache.bindings[canonicalizeKey(directory)] = binding
-  writeCache(cache)
+  await withCacheLock(() => {
+    // Re-read inside the lock so a concurrent write is not clobbered.
+    const existing = readCache()
+    const cache: CacheFile =
+      existing && existing.tenant === key.tenant && existing.apiUrl === key.apiUrl
+        ? existing
+        : { version: CACHE_VERSION, tenant: key.tenant, apiUrl: key.apiUrl, bindings: {} }
+    cache.bindings[canonicalizeKey(directory)] = binding
+    writeCache(cache)
+  })
 }

Route the migration write in readLocalBinding through the same lock. Note that this guards only one process; a concurrent CLI process still races, so consider dropping the migration write from the read path entirely and migrating only inside recordApprovedBinding.

As per coding guidelines: "Protect shared session, worker, cache, dispatcher, and file-write state from async races".

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.

…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)

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.

  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)

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.

…fect, 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.

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

WARNING: Install-failure drain misses sessions that joined the shared install promise after the snapshot

A second scan arriving while the install is in flight takes the early return at line 62 (if (workspacePromptInstall) return workspacePromptInstall) after already adding its sessionID at line 60 — so it is not in armingSessions, yet its caller still resolves the shared install promise as success. If the install then fails, this loop drains only the snapshot, leaving that session in pendingWorkspacePromptSessions with no listener installed: its idle event never publishes the postScan prompt, and the stale entry lingers until an unrelated later scan re-arms. Since a failed install leaves no listener, every pending entry is uncovered regardless of when it was added — clear() is both complete and lets the armingSessions snapshot be deleted:

WARNING: map runs before the row filter, so a null row element throws instead of being dropped

The envelope guards above exist to stop malformed shapes "taking the picker down before it renders", but a single null (or non-object) element inside an otherwise-valid array still makes d.id here throw TypeError before the .filter on the next line can drop it — the exact picker-down failure this hunk was hardened to prevent. Making the map null-safe lets the existing typeof d.name === "string" / integer-id filter discard malformed rows instead of erroring the whole list:

SUGGESTION: One identity-less row discards the entire cache file, not just that row

isValidCacheFile is all-or-nothing and readCache() returns null on any row failure, so if an identity-less row ever lands in the file (hand-edit, future writer, or a server-row shape change on the warm path at workspace.tsx:988), every other project's valid binding is silently dropped, the warn mislabels it as corruption, and the next recordApprovedBinding rebuilds the cache from scratch — wiping sibling entries. Current writers always populate the matched identifier, so this is hardening rather than a reachable bug today, but skipping just the offending row (or dropping it inside migrateToCanonicalKeys) would confine the loss to the one unverifiable entry this check protects against.

git compares ceiling entries against the child's physically resolved cwd, and on macOS os.tmpdir() returns a symlinked path (/var/folders/.../private/var/...).

SUGGESTION: No regression test for the .git/ trailing-slash case this fixes

The reordering correctly fixes foo/bar.git/bar, but the projectNameFromRemote describe block (workspace.test.ts:88-104) pins only bar.git, bare bar, and bar/ — not bar.git/. Without a pinned case, a future refactor collapsing this chain back to a two-step order could silently regress the exact bug this commit fixes.

SUGGESTION: No coverage for the null-scope (unscoped fallback) branch

Alongside the scoping change, skipKey gained the scope: LatchScope | null fallback (null → unscoped key, reachable via currentLatchScope() when credentials are unavailable), but the updated tests only exercise non-null scopes. A small addition here — recordSkip(api, ident, null, now) then assert isSkipActive(api, ident, null, now) is true and isSkipActive(api, ident, scope, now) is false — would pin the fallback key shape and its independence from scoped latches.

…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).

Claude-Session: https://claude.ai/code/session_016H42Vt4pt5dcD7opRqckeM
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).

300-321: 🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Attach a persistent error handler after the bind succeeds.

Line 307 removes onErr after a successful listen. The server then has no error listener for the remaining 15-minute window. A post-bind server error, for example EMFILE on accept, emits an unhandled error event and terminates the CLI process. Route post-bind errors into pending.reject.

Close the listener if the flow settled before startListener resolved.

closeListener is a no-op while startListener is still pending, because listenerHandle is undefined. If the timeout fires or the AbortSignal fires in that window, the outer promise settles first. Line 450 then assigns listenerHandle to a listening server that nothing closes. The loopback port stays bound for the rest of the process lifetime. Track a settled flag and close the handle immediately when the assignment happens after settlement.

As per coding guidelines: "Protect shared session, worker, cache, dispatcher, and file-write state from async races; ensure cleanup runs on success, error, and cancellation paths, preferably with finally."

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

isBrowserHandoffAvailable still rejects when the credentials read fails.

Line 63 guards isConfigured() with .catch(() => false), but line 64 calls AltimateApi.getCredentials() unguarded. getCredentials throws when the credentials file is missing between the two calls, when the JSON is invalid, or when the schema parse fails. runFlow awaits this at line 990 before the pre-check, so a single unreadable credentials file aborts the whole post-scan flow and shows only the generic "Workspace setup failed" toast from reportFlowFailure. The browser option is optional, so a failure here must degrade to false.

currentLatchScope at lines 123-131 already applies this pattern with an outer try/catch. Reuse one credential read for both values to remove the duplicate I/O and the window where the two reads disagree.

🛡️ Proposed fix: contain credential failures and read credentials once
 async function isBrowserHandoffAvailable(): Promise<boolean> {
-  if (!(await AltimateApi.isConfigured().catch(() => false))) return false
-  const creds = await AltimateApi.getCredentials()
-  return resolveWorkspaceWebUrl(creds.altimateUrl, creds.altimateInstanceName) !== null
+  try {
+    if (!(await AltimateApi.isConfigured())) return false
+    const creds = await AltimateApi.getCredentials()
+    return resolveWorkspaceWebUrl(creds.altimateUrl, creds.altimateInstanceName) !== null
+  } catch {
+    return false
+  }
 }

Optional follow-up: derive both latchScope and browserAvailable in runFlow from one getCredentials() observation instead of calling currentLatchScope() and isBrowserHandoffAvailable() separately at lines 972 and 990.

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift

Make temporary-state setup safe for parallel Bun tests.

XDG_STATE_HOME and GIT_CEILING_DIRECTORIES are process-global. afterAll and finally restore them, but they do not prevent another test file from reading the temporary values while this file runs. Another module import can also resolve its cache path to SANDBOX.

Move the state behind per-test dependency injection, or run this setup in an isolated worker or subprocess. Do not rely on module-level os.tmpdir() plus process-environment mutation for parallel execution.

If this is a new test file, use tmpdir from fixture/fixture.ts with await using tmp = await tmpdir() per test, and adapt the module boundary so the test does not require process-global setup.

As per coding guidelines: tests with shared state must provide teardown and isolation safe for parallel bun test execution. Based on learnings: brand-new tests under packages/opencode/test/altimate/ must use the documented tmpdir() fixture with per-test scoping instead of the legacy module-level os.tmpdir() pattern.

SUGGESTION: Gate on preCheckOk too, not just !existing

When getBindingForProject throws (network/5xx), preCheckOk is false but existing stays null — so this new gate still offers "Set up in browser" when the project may already be linked server-side. The user then completes the browser flow (creating a real, billable SaaS workspace) only for bindExisting to 409: the exact stranded-workspace outcome this gate was added to prevent. Reaching it only requires the binding lookup to fail while listDatamates (line 95) succeeds, e.g. a transient 5xx on one endpoint. Consider browserAvailable && !existing && preCheckOk. The 409 handler does explain recovery, so this is tightening the new gate rather than a fresh failure path.

SUGGESTION: void err is a no-op — use an optional catch binding and keep a diagnostic

catch (err) whose only use is void err simplifies to } catch { (deleting this statement). As written the rejection vanishes with no log — if showLinkedConfirmation starts failing systematically (e.g. a dialog-teardown regression), every success silently downgrades to the toast with nothing to debug. Prefer catch plus log.warn("linked confirmation failed", { err: String(err) }) — a log is already in scope in this file.
