PostCascadeDelete_Returns404: simulate post ON-DELETE-CASCADE state (empty rows) → List returns 404 as expected after workspace deletion. 5. AuthGate_NoToken_Returns401: router-level test with WorkspaceAuth middleware; POST/GET/DELETE all return 401 without a bearer token (no DB calls made). workspace-template — _save_checkpoint + 4 Python tests: - Add async _save_checkpoint() to temporal_workflow.py: POST to the platform checkpoint endpoint after each activity stage; fully non-fatal (try/except inside the function, plus defence-in-depth try/except at every call site). - 4 new pytest cases (test_temporal_workflow.py): - nonfatal_on_http_error: _save_checkpoint raises HTTPStatusError (500) → task_receive_activity still returns {"status":"received"}. - nonfatal_on_network_error: _save_checkpoint raises ConnectError → llm_call_activity still returns success LLMResult. - success_path: _save_checkpoint no-op → activity returns correctly; checkpoint called with correct args. - standalone_http_error_is_swallowed: real _save_checkpoint function swallows HTTP 500 from a mocked httpx.AsyncClient; returns None. All 36 temporal workflow Python tests pass. Go tests: Go binary not in this container; test file verified for syntax and against the sqlmock patterns used throughout the handlers package.

Rotate tokens regularly. Revoke via `DELETE /workspaces/:id/tokens/:token_id`. + +## 6.

From 3c260d65a9030bb36d52584027be7a87731a71f5 Mon Sep 17 00:00:00 2001 From: Molecule AI Backend Engineer Date: Fri, 17 Apr 2026 20:52:20 +0000 Subject: [PATCH 17/48] fix(platform): atomic hibernate via UPDATE WHERE active_tasks=0 (#819) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replaces the racy SELECT-then-Stop two-step in HibernateWorkspace with a three-step atomic pattern that eliminates the TOCTOU window (SAFE-819): 1. Atomic claim: single UPDATE WHERE id=$1 AND status IN ('online','degraded') AND active_tasks = 0 — rowsAffected=0 means another caller already claimed it or tasks arrived; we abort immediately without calling Stop. 2. provisioner.Stop: safe because status='hibernating' blocks new task routing between step 1 and step 2 (no new task can be dispatched). 3. Final UPDATE to 'hibernated': records the completed hibernation. Also adds stopFnOverride func(ctx, id) to WorkspaceHandler (always nil in production) so tests can count Stop calls without a running Docker daemon.

Slug validation: regex ^[a-zA-Z0-9 _-]+$ rejects path traversal and special chars in [slug] routing Improvements: 5. Shared HTTP client (slackHTTPClient) for connection pooling instead of per-request &http.Client{} 6. Rune-safe truncation in BroadcastToWorkspaceChannels for CJK/emoji 7.

This gives each agent ambient awareness of what peers are doing: - Backend sees Frontend posted 'PR #840 ready for review' → can check - Security Auditor sees Backend posted 'new endpoint added' → plans review - PM sees all engineering activity → better synthesis in rollup Implementation: - slack.go: FetchChannelHistory() calls conversations.history, filters bot's own messages, returns last N as SlackHistoryMessage structs - manager.go: FetchWorkspaceChannelContext() looks up the workspace's Slack config, fetches history, formats as readable context block - scheduler.go: ChannelBroadcaster interface extended with FetchWorkspaceChannelContext; fireSchedule injects context before the cron prompt (prepended, not appended, so the agent sees team context BEFORE its task instructions) Best-effort: if Slack API fails or workspace has no channels, the prompt is unchanged. Truncated to 200 chars per message, 10 messages max to keep prompt overhead bounded.

WCAG 4.1.3 (Status Messages): the confirmation UI that appears when the user clicks "Delete Workspace" had no ARIA live region, so screen readers never announced the confirmation prompt. Adding role="alert" to the confirmation container makes it an implicit assertive live region that is announced immediately. 2. WCAG 2.4.3 (Focus Order): pressing Cancel left focus wherever the browser placed it (often body). Keyboard users had to re-navigate to find the Delete Workspace button. The Cancel handler now calls deleteButtonRef.current?.focus() to return focus to the trigger button, matching the expected modal/disclosure focus-management pattern.

modal lacked focus trap, Escape handling, aria-modal, and aria-labelledby. Migrated to the codebase-standard Radix Dialog pattern (same as CreateWorkspaceDialog and SettingsPanel) which provides all required WCAG 2.1 modal semantics automatically: • Dialog.Root + Dialog.Portal + Dialog.Overlay + Dialog.Content → role="dialog", aria-labelledby, focus trap, Escape key • Dialog.Title wraps "Conversation Trace" heading → aria-labelledby points to the title element • Dialog.Close asChild on ✕ button with aria-label="Close conversation trace" → accessible name for the dismiss button (WCAG 4.1.2) • Dialog.Close asChild on footer Close button • Backdrop → Dialog.Overlay (z-[59]) + Content wrapper (z-[60]) • All timeline/body content unchanged; only modal scaffolding replaced Added 10 WCAG tests in ConversationTraceModal.a11y.test.tsx covering: dialog presence, accessible name, aria-labelledby, data-state, ✕ button aria-label, close button click, Escape key, and loading indicator. All 732 tests pass, build clean.

Without it, the platform binary compiled without the TokenProvider interface implementation, causing /admin/github-installation-token to return 'no token provider registered'. This forced hourly rolling restarts to refresh GH_TOKEN (the env var from provision time expires after ~60 min). Each restart also required re-applying 6 manual patches and caused ~2 min of A2A downtime where agents reported peers as 'unresponsive'. With this fix, the gh-wrapper in each container auto-refreshes tokens via the platform endpoint on every gh call. Zero restarts needed.

to AllowedUpdates in Telegram polling. When CEO clicks Yes/No inline keyboard buttons: 1. Acknowledges press (removes loading spinner) 2. Updates message with 'CEO approved/rejected' 3. Routes 'CEO_DECISION: approve:xyz' as inbound to the agent Only one workspace polls per bot token (Triage Operator) — other workspaces with Telegram use outbound-only via direct API. Fixed: duplicate pollers causing 'terminated by other getUpdates' errors — removed PM/DevLead/ResearchLead Telegram channel rows (they send outbound via direct Telegram API calls, not channel manager).
