From 28ef75d25e69e92a4cbdf5aa2beaba63d2a437b0 Mon Sep 17 00:00:00 2001 From: Hongming Wang Date: Tue, 5 May 2026 04:33:06 -0700 Subject: [PATCH 01/33] refactor(workspace): split mcp_cli.py (626 LOC) into focused modules (RFC #2873 iter 3) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Splits the standalone molecule-mcp wrapper into three single-concern modules per the OSS-shape refactor program: * mcp_heartbeat.py — register POST + heartbeat loop + auth-failure escalation + inbound-secret persistence * mcp_workspace_resolver.py — single + multi-workspace env validation + on-disk token-file read + operator-help printer * mcp_inbox_pollers.py — activate inbox singleton + spawn one daemon poller per workspace mcp_cli.py becomes a 193-LOC orchestrator: validates env, calls each module's helpers, hands off to a2a_mcp_server.cli_main. The console- script entry molecule-mcp = molecule_runtime.mcp_cli:main is preserved. Back-compat aliases (mcp_cli._build_agent_card, _heartbeat_loop, _resolve_workspaces, etc.) re-export the new modules' authoritative functions so existing tests + wheel_smoke.py + any downstream caller keeps working unchanged. A new test file pins each alias as the exact same callable (drift gate via `is`). Tests: * 62 existing test_mcp_cli.py + test_mcp_cli_multi_workspace.py pass against the split. * Two heartbeat-loop persist tests + the auth-escalation caplog setup updated to target mcp_heartbeat (the module where the loop body now lives) instead of mcp_cli (still works through aliases for direct calls, but Python's name resolution inside the loop body uses the new module's namespace). * test_mcp_cli_split.py adds 11 new tests: alias drift gate + inbox-poller single + multi-workspace branches + degraded inbox-import logging path (none of those existed before).

Cache `platform-pending: → workspace:` so the eventual chat message that REFERENCES the upload (separate, later activity row) gets URI-rewritten before the agent sees it. Inbox poller extension (workspace/inbox.py): - is_chat_upload_row(row) discriminator on `method` - upload-receive rows trigger fetch_and_stage and are NOT enqueued as InboxMessages (they're side-effect rows, not chat messages) - cursor advances past them regardless of fetch outcome — a permanent /content failure must not stall the cursor and block real chat traffic - message_from_activity calls rewrite_request_body to swap platform-pending: URIs to local workspace: URIs in subsequent chat messages' file parts. Cache miss leaves the URI untouched so the agent surfaces an unresolvable URI rather than the inbox silently dropping the part. Filename sanitization mirrors workspace-server/internal/handlers /chat_files.go::SanitizeFilename and workspace/internal_chat_uploads .py::sanitize_filename — pinned by the existing parity test suites.

The phantom-busy sweep in workspace-server/internal/scheduler/scheduler.go already logs each row reset, but no aggregate metric surfaces "how often is this firing." A regression that causes high reset rates (e.g. controlplane#481's missing env vars, or future drift in the workspace runtime's task-lifecycle accounting) only surfaces when users complain. Fix: counter exposed at /metrics as molecule_phantom_busy_resets_total, incremented from sweepPhantomBusy after each row whose active_tasks was reset. Same shape as existing molecule_websocket_connections_active. Operator-side dashboard: alert when daily phantom-busy reset count > 0.5% of active workspaces. Today's steady-state is near-zero; any increase is a regression signal. Tests: - TestTrackPhantomBusyReset_IncrementsCounter - TestTrackPhantomBusyReset_RaceFreeUnderConcurrentWrites (50×200 concurrent writes; tests atomic invariant) - TestHandler_ExposesPhantomBusyResetsCounter (asserts HELP + TYPE + value lines in Prometheus text format) - TestHandler_PhantomBusyResetsZeroByDefault (fresh-process 0 contract — prevents a future refactor from accidentally dropping the metric from /metrics) Race-detector clean. Vet clean.

Stack atop Phase 2. The platform's pending_uploads table grows once-per-uploaded-file with no built-in cleanup. Phase 1's hard TTL (expires_at default 24h) makes expired rows un-fetchable but doesn't actually delete them; Phase 1's ack stamps acked_at but leaves the row indefinitely. Without a sweep the table grows unbounded across normal traffic. This PR adds: - `Storage.Sweep(ctx, ackRetention)` — a single round-trip CTE that deletes acked rows past their retention window plus unacked rows past expires_at. Returns `(acked, expired)` deletion counts so Phase 3 dashboards can spot the stuck-fetch pattern (high expired, low acked) vs healthy churn. - `pendinguploads.StartSweeper(ctx, storage, ackRetention)` — background goroutine that calls Sweep every 5 minutes (default). Runs once immediately on startup so a platform restart cleans up any rows that became eligible while we were down. - Prometheus counters `molecule_pending_uploads_swept_total` with `outcome={acked,expired,error}` labels. Wired into the existing `/metrics` endpoint. - Wired from cmd/server/main.go via supervised.RunWithRecover — one transient panic doesn't take the platform down with it. Defaults: - SweepInterval = 5m (matches the dashboard refresh cadence) - DefaultAckRetention = 1h (gives the workspace at-least-once retry headroom in case it processed but failed to write the file before crashing) Test coverage: 100% on storage_test.go (extended with sweepSQL pin + six Sweep test cases including negative-retention clamp + zero-retention immediate-delete + DB error wrapping) and sweeper_test.go (ticker-driven + ctx-cancel + nil-storage + transient-error-doesn't-crash + metric counter assertions).

RFC #2872 cited this as a silent false-pass mode: a future refactor that adds an audit-table INSERT literal earlier in source than the real workspaces INSERT would make the gate point at the wrong target. Replaces the byte-search with a go/ast walk + a regex that requires `\s*\(` after `workspaces` — distinguishes the real target from prefix lookalikes. Adds three discriminating tests: - TestWorkspacesInsertRE_RejectsLookalikes — pins the regex against 9 sql shapes (real, raw-string-literal, audit-shadow, workspace_* prefixes, canvas_layouts, UPDATE/SELECT, comments). - TestGate_FailsWhenLookupAfterInsert — synthesizes Go source where the lookup is positioned AFTER the workspaces INSERT, asserts the helper returns lookupPos > insertPos (which the production gate flags via t.Errorf). Proves the gate isn't vestigial. - TestGate_IgnoresAuditTableShadow — synthesizes source with an audit-table INSERT BEFORE the lookup + real INSERT, asserts the tightened regex correctly walks past the shadow and finds the real INSERT. Also extracts findLookupAndWorkspacesInsertPos as a helper so the gate logic can be exercised against synthetic source, not only against the real org_import.go. Memory: feedback_assert_exact_not_substring.md (verify tightened test FAILS on old code) — TestGate_FailsWhenLookupAfterInsert is the failing-on-bug-shape proof. Closes the silent-false-pass mode of #2872 Important-1.

Three sites quietly disagreed on the default: - canvas CreateWorkspaceDialog (line 126): isSaaS ? 4 : 3 ← only correct one - canvas EmptyState "Create blank": tier: 2 ← hardcoded - workspace.go POST /workspaces: tier = 3 ← not SaaS-aware - org_import.go createWorkspaceTree: tier = 2 (fallback)← not SaaS-aware So a user clicking "+ New Workspace" via the dialog got T4 on SaaS, but a user clicking "Create blank" on the empty canvas got T2, and an agent POSTing /workspaces directly got T3. Same tenant, three different tiers depending on entry point. Fix: 1. WorkspaceHandler.IsSaaS() and DefaultTier() helpers (workspace_dispatchers.go). IsSaaS() := h.cpProv != nil — single source of truth for "are we SaaS" across the file. DefaultTier() returns 4 on SaaS, 3 on self-hosted. SaaS rationale: each workspace runs on its own sibling EC2 so the per-workspace tier boundary is a Docker resource limit on the only container present — no neighbour to protect from. T4 matches the boundary. 2. workspace.go now defaults tier via h.DefaultTier() instead of hardcoded T3. 3. org_import.go fallback (when neither ws.tier nor defaults.tier set) becomes SaaS-aware: T4 on SaaS, T2 on self-hosted (preserve the existing safe-shared-Docker-daemon default for self-hosted org imports). 4. canvas EmptyState "Create blank" stops sending tier:2 in the body and lets the backend pick — single source of truth in the backend. Eliminates the third disagreement.

Root cause is a race between two goroutines, not a bug in the production sweeper. The fake `fakeSweepStorage.Sweep` signals `cycleDone` from inside its deferred return — that happens BEFORE Sweep's return value is received by `sweepOnce`, which is what triggers the metric increment. On slow CI hosts the test goroutine wins the read after `waitForCycle` unblocks and BEFORE StartSweeper's goroutine has called `metrics.PendingUploadsSweepError`, so the asserted delta is 0 even though the metric WILL be 1 a few ms later. Adds a polling assert helper, `waitForMetricDelta`, that closes the race deterministically without timing-based sleeps: - TestStartSweeper_RecordsMetricsOnError uses waitForMetricDelta to wait for the error counter to settle at 1. - TestStartSweeper_RecordsMetricsOnSuccess uses it on the success counters (acked, expired) so the error-stayed-zero assertion reads after StartSweeper has fully processed the cycle. - waitForCycle keeps its current shape but documents the caveat in its comment so future tests don't repeat the assumption. Verified: `go test ./internal/pendinguploads/ -race -count 5` passes all 9 tests across 5 iterations cleanly. Per memory feedback_question_test_when_unexpected.md: the "delta=0, want=1" failure looked like a real production bug at first glance, but instrumented inspection showed the metric DOES increment, just AFTER the test's read. The fix is the test's wait shape, not the sweeper. Unblocks every PR currently broken by this flake (#2898 hit it on two consecutive CI runs; staging-merged PRs from earlier today (#2877/#2881/#2885/#2886) introduced the test).

Root cause: ChatTab.tsx:548 fires `bottomRef.scrollIntoView({ behavior: "smooth" })` on every messages-update. On initial mount with N messages already loaded, the smooth-scroll triggers a ~300ms animation that any concurrent React re-render (agent push landing, theme toggle, sidepanel resize) interrupts mid-flight, leaving the user stuck somewhere in the middle of the conversation. Fix: track first-mount via hasInitialScrollRef. Use behavior:"instant" for the initial jump (deterministic, no animation interruption), then smooth for subsequent appends (the new-message-landing visual stays). Refs flipped on first messages.length > 0 transition, so: - Initial open of chat tab: instant jump to bottom ✓ - New agent message arrives: smooth scroll into view ✓ - Workspace switch (ChatTab remounts): fresh hasInitialScrollRef, gets instant again ✓ - loadOlder prepend: anchor-restore path unchanged, still pins user's reading position ✓ Test plan: - pnpm test --run ChatTab.lazyHistory.test.tsx → 8 pass (existing lazy-history tests untouched) - npx tsc --noEmit clean - Manual on hongming.moleculesai.app: open a busy chat (mac laptop, ~50 messages), confirm view lands at the latest bubble, not mid- scroll.

Without this PR an operator wanting to flip MEMORY_V2_CUTOVER=true had to provision a separate memory-plugin service and point MEMORY_PLUGIN_URL at it — extra ops surface for what the design intends to be a built-in. What ships: * Both Dockerfile + Dockerfile.tenant build the cmd/memory-plugin-postgres binary into /memory-plugin. * Entrypoints spawn the plugin in the background on :9100 BEFORE starting the main server; wait up to 30s for /v1/health to return 200; abort boot loud if it doesn't (better to crash-loop than to silently route cutover traffic against a dead plugin). * Default env: MEMORY_PLUGIN_DATABASE_URL=$DATABASE_URL (share the existing tenant Postgres — plugin's `memory_namespaces` / `memory_records` tables coexist with platform schema, no conflicts), MEMORY_PLUGIN_LISTEN_ADDR=:9100. * MEMORY_PLUGIN_DISABLE=1 escape hatch for operators running the plugin externally on a separate host. * Platform image: plugin runs as the `platform` user (not root) via su-exec — matches the privilege boundary the main server already drops to. Tenant image already starts as `canvas` so the plugin inherits non-root automatically. What stays operator-controlled: * MEMORY_V2_CUTOVER is NOT auto-set. Behavior change for existing deployments: zero. The wiring at workspace-server/internal/memory/ wiring/wiring.go skips building the plugin client until the operator opts in, so the running sidecar is a no-op for traffic until then. * MEMORY_PLUGIN_URL is NOT auto-set either, for the same reason — setting it implies cutover-active intent. Operators set both on staging first, verify a live commit/recall round-trip (closes pending task #292), then promote to production. Operator activation steps after this PR ships: 1. Verify pgvector extension is available on the target Postgres (the plugin's first migration runs CREATE EXTENSION IF NOT EXISTS vector). Railway's managed Postgres ships pgvector available; some self-hosted operators may need to enable it. 2. Redeploy the workspace-server with this image. 3. Set MEMORY_PLUGIN_URL=http://localhost:9100 + MEMORY_V2_CUTOVER=true in the environment (staging first). 4. Watch boot logs for "memory-plugin: ✅ sidecar healthy" and the wiring.go cutover messages; do a live commit_memory + recall_memory round-trip via the canvas Memory tab to verify. 5. Promote to production once staging holds for a sweep window. Refs RFC #2728.

Bundled because every change is in the platform's pending_uploads layer or the multi-file handler that reads it. Findings resolved: 1. Important — Sweep query lacked an index for the acked-retention OR-arm. The Phase 1 partial indexes are both `WHERE acked_at IS NULL`, so the `(acked_at IS NOT NULL AND acked_at < retention)` half of the WHERE clause seq-scanned the table on every cycle. Add a complementary partial index on `acked_at WHERE acked_at IS NOT NULL` so both arms of the disjunction are index-covered. Disjoint from the existing two indexes (no row matches both predicates), so write amplification is bounded to ~one index entry per terminal-state row. 2. Important — uploadPollMode partial-failure left orphans. The previous per-file Put loop committed rows 1..K-1 and then errored on row K with no compensation, so a client retry would double-insert the survivors. Refactor the handler into three explicit phases (pre-validate + read-into-memory, single atomic PutBatch, per-file activity row) and add Storage.PutBatch with all-or-nothing transaction semantics. 3. FYI — pendinguploads.StartSweeperWithInterval was exported only for tests. Move it to lower-case startSweeperWithInterval and expose the test seam through pendinguploads/export_test.go (Go convention; the shim file is stripped from the production binary at build time). 4. Nit — multipart Content-Type was passed verbatim into pending_uploads rows and re-served on /content. Add safeMimetype which strips parameters, rejects CR/LF/control bytes, and coerces malformed shapes to application/octet-stream. The eventual GET /content response can no longer be header-split via a crafted Content-Type on the multipart. Comprehensive tests: - 10 PutBatch unit tests (sqlmock): happy path, empty input, all four pre-validation rejection paths, BeginTx error, per-row error + Rollback (no Commit), first-row error, Commit error. - 4 new PutBatch integration tests (real Postgres): all-rows-commit happy path with COUNT(*) verification, atomic-rollback no-leak via a NUL-byte filename that lib/pq rejects mid-batch, oversize short-circuit no-Tx, idx_pending_uploads_acked existence + partial predicate via pg_indexes (planner-shape-independent). - 3 new chat_files_poll tests: atomic rollback on second-file oversize, atomic rollback on PutBatch error, mimetype CRLF/NUL/parameter sanitization (8 sub-cases). The two remaining review findings (inbox_uploads.fetch_and_stage blocks the poll loop synchronously; two httpx Clients per row) are Python-side and ship in Phase 5b once this lands on staging. Test-only export pattern via export_test.go, atomic pre-validation discipline (validate before Tx), and behavior-based (not name-based) test assertions follow the standing project conventions. --- .../internal/handlers/chat_files.go | 158 +++++++++---- .../internal/handlers/chat_files_poll_test.go | 154 ++++++++++++ .../pending_uploads_integration_test.go | 178 ++++++++++++++ .../internal/handlers/pending_uploads_test.go | 8 + .../internal/pendinguploads/export_test.go | 17 ++ .../internal/pendinguploads/storage.go | 78 +++++++ .../internal/pendinguploads/storage_test.go | 220 ++++++++++++++++++ .../internal/pendinguploads/sweeper.go | 6 +- .../internal/pendinguploads/sweeper_test.go | 5 +- ...00000_pending_uploads_acked_index.down.sql | 2 + ...5200000_pending_uploads_acked_index.up.sql | 30 +++ 11 files changed, 806 insertions(+), 50 deletions(-) create mode 100644 workspace-server/internal/pendinguploads/export_test.go create mode 100644 workspace-server/migrations/20260505200000_pending_uploads_acked_index.down.sql create mode 100644 workspace-server/migrations/20260505200000_pending_uploads_acked_index.up.sql diff --git a/workspace-server/internal/handlers/chat_files.go b/workspace-server/internal/handlers/chat_files.go index ccfa0d4c..f5e980bf 100644 --- a/workspace-server/internal/handlers/chat_files.go +++ b/workspace-server/internal/handlers/chat_files.go @@ -600,14 +600,21 @@ func (h *ChatFilesHandler) uploadPollMode(c *gin.Context, ctx context.Context, w return } - out := make([]uploadedFile, 0, len(headers)) + // Phase 1: pre-validate + read every part BEFORE any DB write. + // A multi-file upload must commit all-or-nothing; a per-file + // failure halfway through used to leave rows 1..K-1 in the table + // while the client got a 500 and retried the whole batch — duplicate + // rows, orphan activity rows.

Important — inbox_uploads.fetch_and_stage blocked the inbox poll loop synchronously per row. A user dragging 4 files into chat at once would stall the poller for 4× per-fetch latency before the chat message reached the agent. Add BatchFetcher: a thread-pool wrapper (default 4 workers) that submits fetches concurrently and exposes wait_all() as the barrier the inbox loop calls before processing the chat-message row that references the uploads. The drain barrier is the correctness invariant: rewrite_request_body must observe a populated URI cache when it walks the chat-message row's parts. _poll_once now drains the BatchFetcher inline before the first non-upload row, AND at end-of-batch (case: batch contains only upload rows; the corresponding chat message arrives in a later poll, but the future-poll-races-current-fetch race is closed). 2. Nit — fetch_and_stage created two httpx.Client instances per row (one for GET /content, one for POST /ack). Refactor so a single client serves both calls. When called from BatchFetcher, the batch-shared client serves every row's GET + ack — so the second fetch reuses the TCP+TLS handshake from the first. Comprehensive tests: - 13 new inbox_uploads tests: - fetch_and_stage with supplied client: zero httpx.Client constructions, GET+POST through the same client, caller's client not closed (lifecycle owned by caller). - fetch_and_stage without supplied client: exactly one httpx.Client constructed (was 2 pre-fix), closed on the way out. - BatchFetcher: 3 rows × 120ms = parallel completion < 250ms (vs. ~360ms serial), URI cache hot when wait_all returns, per-row failure isolation, single-client reuse across all submits, idempotent close, submit-after-close raises, owned-vs-supplied client lifecycle, no-op wait_all on empty batch, graceful httpx-missing degradation. - 3 new inbox tests: - poll_once drains uploads before processing the chat-message row (in-place mutation of row['request_body'] proves the URI was rewritten BEFORE message_from_activity returned). - poll_once with only upload rows still drains at end-of-batch. - poll_once with no upload rows never constructs a BatchFetcher (zero overhead on the no-upload happy path). 133 total inbox + inbox_uploads tests pass; 0 regressions. Closes the chat-upload poll-mode-perf gap end-to-end.

Inside today's deployment that's moot (no host port mapping, platform talks over loopback) but it's not least-privilege. A future Dockerfile edit that publishes the port, a misconfigured Fly machine, or a future cross-host plugin topology would expose an unauth'd memory store. Loopback is the right baseline. Operators with a multi-host topology already override via MEMORY_PLUGIN_LISTEN_ADDR — that path is unchanged. Tests: * TestLoadConfig_DefaultListenAddrIsLoopback pins the new default. * TestLoadConfig_ListenAddrEnvOverride pins the override path so operators relying on it don't break. * TestLoadConfig_MissingDatabaseURL covers the existing fail-fast. No prior unit tests existed for loadConfig — boot_e2e_test.go always sets MEMORY_PLUGIN_LISTEN_ADDR explicitly, so the default was never exercised by tests. This PR adds that coverage.

(#2910 PR-B) template_import.go:79 wrote `tier: 3` hardcoded into generated config.yaml. On SaaS this defeated the T4 default at the create-handler layer — a config-less template import landed at T3 regardless of POST /workspaces' computed default. The 4th default-tier site #2901 missed. 2. (#2910 PR-A) #2901 claimed `go test ... all green` but added zero new tests. Existing structural-pin tests caught dispatch-layer drift but said nothing about tier-default drift. A future refactor that flips DefaultTier() to always return 3 would ship green. 3. (#2910 PR-E) org_import.go fallback returned T2 on self-hosted while workspace.go returned T3. Internally consistent ("bulk vs interactive defaults") but undocumented same-name-different-value drift. Fix: - TemplatesHandler.NewTemplatesHandler now takes `wh *WorkspaceHandler` (nil-tolerant for read-only callers).

Symptoms: test_poll_once_skips_chat_upload_row_from_queue saw fetch_and_stage called twice instead of once on Python 3.11 CI; test_batch_fetcher_owns_client_when_not_supplied saw two Client constructions instead of one in the full local suite.

No filesystem path dependency at runtime. * \`embed.FS\` embeds the .up.sql files alongside the binary. * runMigrations() reads from migrationsFS by default; MEMORY_PLUGIN_MIGRATIONS_DIR override path preserved for operators shipping custom migrations. * Names sorted alphabetically — pinned by a test so a future \`002_*.up.sql\` is guaranteed to run after \`001_*.up.sql\`. Tests: * TestMigrationsEmbedded_ContainsCreateTable — pins that the embed pattern matched files AND those files contain CREATE TABLE (catches both empty-pattern and wrong-files-embedded). * TestRunMigrationsFromEmbed_OrderingIsAlphabetic — pins sorted application order. Verified locally: \`go build\` succeeds, binary 9.3MB, \`strings\` shows the embedded SQL. Refs RFC #2728.

The destructive POST route — which stops EC2s, marks children removed, and deletes layouts — has zero UI callers (verified via grep across canvas/, scripts/, and the MCP tool registry; only docs referenced it). Two semantically different operations had been sharing the word "Collapse": - Visual collapse (canvas) → PATCH { collapsed: true }. Hides children visually. Reversible. UI-only. - Destructive collapse (POST /collapse) → Stops + marks removed. Irreversible. No caller. Deleting the destructive one + its supporting machinery: - workspace-server/internal/handlers/team.go (entirely) - workspace-server/internal/handlers/team_test.go (entirely) - POST /collapse route + teamh init in router.go - findTemplateDirByName helper (zero non-test callers after Expand was deleted in #2856; package-private so no out-of-package consumers) - NewTeamHandler constructor (no callers after route removed) Plus stale doc references (the most dangerous was the MCP wrapper mapping in mcp-server-setup.md — anyone generating MCP tool wrappers from that table was wiring a 404): - docs/agent-runtime/team-expansion.md (deleted entirely — whole guide taught the deleted flow) - docs/api-reference.md (dropped two team.go rows) - docs/api-protocol/platform-api.md (dropped /expand + /collapse rows) - docs/architecture/molecule-technical-doc.md (dropped /expand + /collapse rows) - docs/guides/mcp-server-setup.md (dropped expand_team + collapse_team MCP wrapper mappings) - docs/glossary.md (dropped "(org template expand_team)" parenthetical) - docs/frontend/canvas.md (dropped broken link to deleted team-expansion.md) Kept: docs/architecture/backends.md mention of "TeamHandler.Expand (#2367) bypassed routing on Start" — correct historical context for the AST gate's existence, no live route reference. Visual-collapse path unaffected: canvas/src/components/ContextMenu.tsx:227 → api.patch — unchanged canvas/src/components/WorkspaceNode.tsx:128 → api.patch — unchanged go vet ./... clean. go test ./internal/handlers/ -count 1 — all green (4.3s, no regression).

Root cause: the control plane has had POST /cp/auth/signout (clears the WorkOS session cookie + revokes at the provider) since auth shipped, but no canvas code ever called it. grep across canvas/ for `logout|signOut|signout|sign-out` returned zero results — no helper, no button, no menu entry. Users had no path to log out short of clearing cookies in DevTools. This is a UI gap, not a backend bug. Adding the missing pieces: 1. `signOut()` helper in `canvas/src/lib/auth.ts`: - POST /cp/auth/signout with credentials:include (cross-origin cookie required for tenant subdomain → app subdomain) - Best-effort: a 5xx, 401-stale-cookie, or network failure still redirects the browser to /cp/auth/login. Leaving the user on an authed-looking page after they clicked Sign out is the worst possible UX — that's the precise "logout doesn't work" symptom the report described. - Lands on /cp/auth/login (not the current URL) so the user doesn't loop back into the org they just left via AuthGate's return_to. 2. `AccountBar` component on /orgs page Shell — renders the signed-in email + Sign-out button at the top. Click → signOut() → `Signing out…` → bounces to login. Disabled-while-pending so a double-click can't fire two requests. 3. Tests in `auth.test.ts` (4 new, total 12 pass): - POSTs to the right endpoint with credentials:include - Redirects to /cp/auth/login after success - Redirects EVEN ON network failure (the critical UX invariant) - Redirects on 401 (stale cookie path) The auth-origin resolution (`getAuthOrigin`) is reused so a tenant subdomain (acme.moleculesai.app) correctly POSTs to app.moleculesai.app/cp/auth/signout — same chain that fetchSession + redirectToLogin already use.

The first half of #2913 wired a Sign-out button + signOut() helper that POSTed /cp/auth/signout, but clicking still left the user signed in: WorkOS's browser cookie preserved the SSO session, /cp/auth/login auto-re-authed via SSO, and the user landed back on /orgs. CP PR #485 returns the AuthKit hosted logout URL in the signout response. This change has signOut() navigate the browser there instead of /cp/auth/login. AuthKit clears its cookie + redirects to return_to (configured server-side from APP_URL) → next /cp/auth/login hits a fresh AuthKit, no SSO session, login form actually shows. Defensive parsing: malformed JSON, missing logout_url, or wrong-type logout_url all fall through to the legacy /cp/auth/login fallback, which works locally (DisabledProvider, dev) where there's no SSO to escape. Forward-compat: when CP doesn't have #485 deployed yet, signOut() sees logout_url="" or missing → fallback fires. Order of merge between this and #485 doesn't matter, but the bug isn't actually fixed end-to-end until both ship. Tests added (3 new, 15 total auth.test.ts): - Hosted logout: navigates to logout_url when response includes one. - DisabledProvider path: falls back to /cp/auth/login when "". - Defensive: malformed JSON body → fallback (no crash). - Defensive: non-string logout_url → fallback (no open redirect).

Five boundary sites instrumented for #2867: provision.start — workspace_dispatchers.go (sync + async) provision.skip_existing — org_import.go idempotency hit provision.ec2_started — cp_provisioner.go after RunInstances provision.ec2_stopped — cp_provisioner.go after TerminateInstances ack restart.pre_stop — workspace_restart.go before Stop dispatch These pair with the existing human-prose log.Printf lines (kept). The new records are grep+jq friendly so a future log-aggregation pipeline can reconstruct per-workspace provision timelines without parsing the operator messages — this is the "and debug loggers so it dont happen again" half of the leak-prevention work. Tests: - provlog: emits evt-prefixed JSON, nil-tolerant, marshal-error fallback preserves event boundary, single-line output pinned. - handlers: provlog_emit_test.go pins three call-site contracts: provisionWorkspaceAutoSync emits provision.start with sync=true, stopForRestart emits restart.pre_stop with backend=cp on SaaS, and backend=none when both backends are nil. Field taxonomy is convenience for ops, not contract — payload can grow additively without breaking callers. Behavior gate is the event name + boundary location, per feedback_behavior_based_ast_gates.md.

The inbox poll loop would stall indefinitely on a hung /content fetch instead of returning to chat-message processing. Fix: wait_all now flips self._timed_out and cancels queued (not-yet- started) futures; close() reads that flag and switches to shutdown(wait=False, cancel_futures=True) on the timeout path. Currently-running workers can't be interrupted by Python's threading model, but they're now detached daemons whose blocking httpx call no longer gates the next poll. Healthy path (no timeout) keeps the existing drain-and-wait so a still-queued ack POST isn't dropped mid-write. Two new tests pin both legs of the contract end-to-end: - close-after-timeout-doesn't-block: hung worker, wait_all(0.05s) fires the timeout, close() returns in <1s instead of waiting ~5s for the worker to come back. - close-without-timeout-still-drains: 2 slow workers, wait_all completes cleanly, close() drains both ack POSTs. Resolves the BatchFetcher timeout-cancellation finding from the post-merge five-axis review of Phase 5b.

The plugin's first migration runs \`CREATE EXTENSION vector\` which fails on tenant Postgres without pgvector preinstalled — every staging tenant redeploy aborted at the 30s health gate. CP fail-fast kept running tenants on the prior image (no outage), but the new image was DOA. Caught on staging redeploy 2026-05-05 19:23 with \`pq: extension "vector" is not available\`. Fix: only spawn the sidecar when the operator has flipped the cutover flag — \`MEMORY_V2_CUTOVER=true\` OR \`MEMORY_PLUGIN_URL\` is set. * Aligns the entrypoint to the same opt-in posture wiring.go already uses (it skips building the client when MEMORY_PLUGIN_URL is empty). * Until cutover, the sidecar isn't even running — no migration, no health gate, no boot-time pgvector dependency. * Operators activating cutover already redeploy with the new env vars set; that's when the sidecar starts. By definition they've verified pgvector is available before flipping. * MEMORY_PLUGIN_DISABLE=1 escape hatch preserved; harness fix #2915 becomes belt-and-suspenders (still respected). Both Dockerfile and entrypoint-tenant.sh updated. Behavior change for existing deployments: zero (cutover env vars still unset → sidecar still inert, but now also not running). Refs RFC #2728. Hotfix for #2906; supersedes the migration-path fragility class (the sidecar isn't doing migrations on tenants that won't use it). --- workspace-server/Dockerfile | 27 ++++++++++++++++++--------- workspace-server/entrypoint-tenant.sh | 21 +++++++++++++++------ 2 files changed, 33 insertions(+), 15 deletions(-) diff --git a/workspace-server/Dockerfile b/workspace-server/Dockerfile index ecf43fab..d6754312 100644 --- a/workspace-server/Dockerfile +++ b/workspace-server/Dockerfile @@ -63,21 +63,30 @@ fi # Memory v2 sidecar (built-in postgres plugin).

A call to a registered preflight helper (lookupExistingChild today; extend preflightCallNames as new helpers are introduced). 2. An ON CONFLICT clause in the same SQL literal (idempotent UPSERT, like registry.go). 3. An explicit `// class1-gate: idempotent-by-design` comment in the function body (deliberately awkward — forces a code-review beat). Why this is broader than the existing TestCreateWorkspaceTree_CallsLookupBeforeInsert gate in org_import_idempotency_test.go: that one is hard-coded to one function in one file. This one walks every non-test .go file in the handlers package and applies a structural rule independent of file/function names. A future handler written from scratch in a new file would not have been covered before — now it is. Detection mechanism (per AST): - Collect spans (Lbrace..Rbrace) of every RangeStmt body in each function. Position-based instead of stack-based — ast.Inspect's nil-callback ordering doesn't give per-node pop semantics, so a naive push/pop stack silently miscounts. Position spans are deterministic. - Walk every BasicLit, regex-match `^\s*INSERT INTO workspaces\(` (tightened from bytes.Index "INSERT INTO workspaces" so workspaces_audit literals don't false-positive — same regex used by the existing createWorkspaceTree gate). - For each match: record insertLine, hasONCONFLICT, and the innermost enclosing RangeStmt line (or 0 if not inside any range). - Fail the function if INSERT is inside a range AND no preflight AND no ON CONFLICT AND no allowlist annotation. Self-tests (per `feedback_assert_exact_not_substring.md` — verify gate fails on the bug shape before merging): - TestClass1_GateFiresOnSyntheticBuggySource: synthetic source where INSERT is inside `for _, child := range children` body must trigger the gate's three guards (enclosingRangeLine!=0, hasONCONFLICT=false, no preflight call). - TestClass1_GateAllowsONCONFLICT: synthetic INSERT...ON CONFLICT must NOT trigger the gate (idempotent UPSERT case). - TestClass1_GateAllowsAllowlistAnnotation: function with `// class1-gate: idempotent-by-design` must be skipped. - TestClass1_NoUnpreflightedInsertInsideRange: production sweep over every handler .go file. Currently passes because org_import.go preflights, registry.go ON-CONFLICTs, and workspace.go's Create has no INSERT inside a range body. Verification: - go test ./internal/handlers/... -run TestClass1_ -count=1 → 4/4 PASS - go test ./internal/handlers/... -count=1 → suite green (no pre-existing test broken by the new file) Refs molecule-core#2867 (PR-A Class 1 generic AST gate) Co-Authored-By: Claude Opus 4.7 (1M context) --- .../internal/handlers/class1_ast_gate_test.go | 468 ++++++++++++++++++ 1 file changed, 468 insertions(+) create mode 100644 workspace-server/internal/handlers/class1_ast_gate_test.go diff --git a/workspace-server/internal/handlers/class1_ast_gate_test.go b/workspace-server/internal/handlers/class1_ast_gate_test.go new file mode 100644 index 00000000..bb362364 --- /dev/null +++ b/workspace-server/internal/handlers/class1_ast_gate_test.go @@ -0,0 +1,468 @@ +package handlers + +// class1_ast_gate_test.go — generic Class 1 leak gate per #2867 PR-A. +// +// What this gate prevents: +// The tenant-hongming leak class — a handler iterates a YAML-derived +// slice (ws.Children, sub_workspaces, etc.) and calls +// `INSERT INTO workspaces` inside the loop body without first +// checking whether a workspace with the same (parent_id, name) is +// already there.

Also pins cross-workspace bleed protection (workspace B's bearer on A's URL → 401, B's URL with A's file_id → 404) and the file_id-UUID-parse 400 path. 23 assertions, all green against a local platform (Postgres+Redis+ platform-server stack matches the e2e-api.yml CI recipe verbatim). Why a new script instead of extending test_poll_mode_e2e.sh: that script tests A2A short-circuit + since_id cursor semantics; this one tests the chat-upload path. They share zero handler code on the platform side and would dilute each other's failure messages if combined. Why not the bearerless-401 strict-mode assertion: the platform's wsauth fail-opens for bearerless requests when MOLECULE_ENV=development (see middleware/devmode.go). The CI workflow doesn't set that var, but some local-dev .env files do — the assertion would flap by environment without testing the poll-mode upload contract. The middleware's own unit tests cover strict-mode 401.

Three changes mirror the my-chat patterns from ChatTab: 1. Initial-mount instant scroll. Adds hasInitialScrollRef + switches the scroll hook from useEffect to useLayoutEffect. First arrival of messages → scrollIntoView `instant`; subsequent appends → `smooth` as before. useLayoutEffect runs before paint so the user never sees the panel jump for one frame on every append. 2. Error UI with Retry button. Adds `loadError` state. The history-load .catch now sets the error message; a new branch in the render renders a red alert with the failure text and a Retry button that re-invokes `loadInitial`. Same shape as ChatTab MyChatPanel's `loadError` handling — both surfaces should fail loud, not silent. 3. Extracted `loadInitial` callback. The history-load body becomes a useCallback so the retry button has a stable reference to call. Mirrors ChatTab's loadInitial. Tests (4 new in AgentCommsPanel.render.test.tsx): - Loading state renders the loading copy. - Error state with Retry button renders on rejection; clicking Retry fires a second api.get. - Empty state renders when load succeeds with zero rows. - scrollIntoView is called with behavior=instant on first message arrival (pins the chat-opens-in-middle prevention). Verification: - pnpm test → 1284/1284 pass (1280 prior + 4 new) - tsc --noEmit → clean - 92 → 93 test files, no existing test broken Closes the parity gap raised in chat. The two surfaces now share: loading copy / error UI / empty-state placeholder / scroll behaviour / useLayoutEffect timing.

The bare equality breaks if any future caller wraps the error via fmt.Errorf("…: %w", err) — the no-rows happy path would fall through to the "real DB error" branch and abort the import. errors.Is unwraps. New test TestLookupExistingChild_WrappedNoRows_TreatedAsNotFound pins the fix; verified the test fails on the old `==` shape (build break on unused-import + assertion failure once import dropped). 2. Bounded 5s timeout on lookupExistingChild instead of context.Background(). The createWorkspaceTree call site runs in goroutines spawned from the /org/import handler, so plumbing the request context here would cascade-cancel into provisionWorkspaceAuto and abort in-flight EC2 provisioning if the client disconnected mid-import — that's the wrong tradeoff. A short bounded timeout protects the per-row SELECT against a wedged DB without taking the drop-everything-on-disconnect behaviour. The lookup is a single ~10ms query; 5s leaves 500x headroom for transient slow paths. 3. Godoc clarifications on the skip-path block. - /org/import is ADDITIVE-ONLY, never destructive. Children present in the existing tree but absent from the new template are preserved (no DELETE on diff). - Skip-path does NOT propagate updates to existing nodes — a re-import that adds an initial_memory or schedule to an existing workspace is silently dropped. Document the limitation so future operators know to delete-and-re-import or reach for a future /org/sync route.

CI catches this as 7 failures: JSONDecodeError on empty bodies and "All connection attempts failed" on the recall side. Update 7 patch sites to `a2a_tools_memory.httpx.AsyncClient`. The existing tests in `test_a2a_tools_impl.py` were already updated by the iter-4c PR; only these two files were missed. Verified: pytest workspace/tests/test_mcp_memory.py + test_secret_redact.py — 43/43 pass after the fix (both files were red on the iter-4c branch CI).
