Summary

When GITHUB_APP_ID / INSTALLATION_ID are unset (post org suspension or Gitea-canonical deployments without GitHub App), the fallback path in GetInstallationToken was returning 500 Internal Server Error. This pollutes platform logs with ~28×false-positive 500s/hour across all workspaces polling hourly.

Return 501 Not Implemented with {"error":"GitHub integration not configured","scm":"gitea"} when the "required" error fires. Callers (workspace polling loop) can now distinguish "feature off" from "transient error" and stop polling.

Changes

  • workspace-server/internal/handlers/github_token.go: after generateAppInstallationToken() fails, check if the error contains "required" — if so, return 501 instead of 500. Other errors (network failures reading private key, etc.) still return 500.
  • workspace-server/internal/handlers/github_token_test.go: rename TestGitHubToken_NoTokenProviderTestGitHubToken_NoTokenProvider_MissingConfigReturns501 and assert 501 shape with {"error":..., "scm": "gitea"}.

Test plan

  • Go vet
  • 110 workspace Python tests pass
  • CI Go tests (go not available locally)

Adds back the original GitHub workflow's auto-publish trigger that was
dropped during the 2026-05-10 .gitea port (#206). Push to main or
staging filtered by workspace/** falls into the existing PyPI-latest
auto-bump path — no logic changes, just the missing trigger and a
comment correction.

Caveat: the workflow still requires PYPI_TOKEN as a repository secret
(or org-level). Without it the publish step will fail loudly with a
descriptive error. Q2 follow-up tracks setting the secret.

Refs: molecule-core#348
publish-runtime.yml has never fired since the .gitea port (0 rows in
action_run.workflow_id='publish-runtime.yml' ever), which is why PyPI
is still at 0.1.129 despite Gitea having a runtime-v1.0.0 tag.

Root cause hypothesis: Gitea Actions evaluates the on.push.paths filter
against tag-push events too (no path diff → workflow skipped). PR #349
made this visible by adding the paths trigger, but the same defect
existed for the originally-ported tags-only trigger on this Gitea version
— hence the runtime-v1.0.0 tag also never published.

Fix: split into two files, each with a single unambiguous trigger shape.

  - publish-runtime.yml          : on.push.tags only       (the publisher)
  - publish-runtime-autobump.yml : on.push.branches+paths  (NEW; the bumper)

The autobump file computes next version from PyPI latest, pushes
'runtime-v$VERSION' tag via DISPATCH_TOKEN (not GITHUB_TOKEN — needed
to trigger downstream workflows on Gitea), and exits. The tag push
then triggers publish-runtime.yml.

Test plan after merge:
  1. Push no-op commit to workspace/. Observe autobump fire, push tag.
  2. Observe publish-runtime.yml fire on the tag, publish 0.1.130 to
     PyPI, cascade to template repos.
  3. Verify 'action_run' shows >0 rows for both workflow_ids.
ROOT CAUSE found in Gitea server logs:

  actions/workflows.go:DetectWorkflows() [W] ignore invalid workflow
  "publish-runtime.yml": unknown on type:
  map["version":{"description":...,"required":true,"type":"string"}]

Gitea 1.22.6's workflow parser flattens workflow_dispatch.inputs.* into
top-level 'on:' event-keys and rejects the workflow when it doesn't
recognize them. Once rejected, the workflow never registers — so NO
event triggers it. publish-runtime.yml has 0 runs in action_run since
the .gitea port for exactly this reason; the runtime-v1.0.0 tag from
yesterday and hongming-pc's runtime-v0.1.130 from tonight both pushed
successfully but went nowhere.

This supersedes the paths-vs-tags hypothesis from #351 (PR #352).
The split is still useful for clarity but was NOT the cause — even
the original tags-only port had this same parse failure.

Fix: drop the inputs block. workflow_dispatch in Gitea 1.22.6 supports
no-input dispatch only. The bash logic for version derivation now uses
just two cases: tag-push (strip prefix) or anything-else (PyPI auto-bump).

Post-merge verification:
  - watch for first-ever publish-runtime.yml run in action_run
  - check Gitea log no longer emits 'ignore invalid workflow' for this file
  - push a runtime-v0.1.130 tag → workflow fires → PyPI 0.1.130

Implements the Claude Design handoff (Molecules AI Mobile.html) as a
viewport-gated React tree under canvas/src/components/mobile/. < 640px
renders the new shell instead of the desktop ReactFlow canvas.

Six screens, all bound to live store data:
- Home (agent list + filter chips + spawn FAB)
- Canvas (mini-graph with pinch-to-zoom + pan + reset)
- Detail (status pills, tabs: Overview / Activity / Config / Memory;
  Activity hits /workspaces/:id/activity)
- Chat (textarea composer, IME-safe Enter, sendInFlightRef guard;
  bootstraps from agentMessages so the prior thread shows on entry)
- Comms (live A2A feed via /workspaces/:id/activity + ACTIVITY_LOGGED)
- Spawn (bottom sheet; fetches /templates so users pick what's actually
  installed on their platform)

Plus a Me tab for mobile theme/accent/density.

Design system (palette.ts + primitives.tsx) ports tokens 1:1 from the
handoff: cream + dark palettes, T1-T4 tier chips, status dots with
halo, JetBrains Mono for IDs/timestamps. Inter + JetBrains Mono are
self-hosted via next/font/google so CSP `font-src 'self'` is honoured.

URL routing: routes sync to ?m=<route>&a=<id>; popstate restores route;
deep links seed initial state. /?m=detail without ?a collapses to home.

Accent override flows through React context (MobileAccentProvider) —
not by mutating the static MOL_LIGHT/MOL_DARK singletons.

SSR flash: isMobile is tri-state; loading spinner stays up until
matchMedia resolves so mobile devices never paint the desktop tree.

Desktop responsiveness fixes (separate but ride along):
- Toolbar: full-width with overflow-x-auto on mobile, logo text + count
  hidden < sm, divider/border collapse to sm: only.
- SidePanel: full-screen on mobile via matchMedia, resize handle hidden.
- Canvas: MiniMap hidden < sm (was overlapping the New Workspace FAB).

Tests (51 total, 33 new):
- palette.test.ts (12) - normalizeStatus, tierCode, light/dark parity
- components.test.ts (10) - toMobileAgent field mapping + classifyForFilter
- MobileApp.test.tsx (12) - route stack, deep links, popstate, tab bar
  hidden on chat, spawn overlay
- SidePanel.tabs.test.tsx (18) - regression-clean

Verified: tsc --noEmit clean across mobile/, page.tsx, layout.tsx.
Not yet verified: live phone browser (needs CP backend hydrated).

Root cause (from infra-lead PR#7 review id=724):
Sanitization in PR#7 wrapped peer text in [A2A_RESULT_FROM_PEER]
markers, but the markers themselves were not escaped — a malicious
peer could inject "[/A2A_RESULT_FROM_PEER]" to close the trust
boundary early, making subsequent text appear inside the trusted zone.

Fix:
- Create workspace/_sanitize_a2a.py (leaf module, no circular import
  risk) with shared sanitize_a2a_result() + _escape_boundary_markers()
- _escape_boundary_markers() escapes boundary open/close markers in the
  raw peer text before wrapping (primary security control)
- Defense-in-depth: also escapes SYSTEM/OVERRIDE/INSTRUCTIONS/IGNORE
  ALL/YOU ARE NOW patterns (secondary, per PR#7 design intent)
- Update a2a_tools_delegation.py: import from _sanitize_a2a; wrap
  tool_delegate_task return and tool_check_task_status response_preview
- Add 15 tests covering boundary escape, injection patterns, integration
  shapes (workspace/tests/test_a2a_sanitization.py)

Follow-up (non-blocking, noted in PR#7 infra-lead review):
- Deduplicate if a2a_tools.py also wraps (currently handled in
  delegation module only — callers get sanitized output regardless)
- tool_check_task_status: consider sanitizing 'summary' field too

Closes: molecule-ai/molecule-ai-workspace-runtime#7 (wrong-repo PR
that this supersedes)

Trivial empty commit to force a fresh workflow run now that the
PR has tier:low label and approvals on the rebased branch.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Gitea Actions reads .gitea/workflows/, not .github/workflows/. The
.github/ copy of this workflow has been kept in lockstep with .gitea/
since the post-suspension migration (e.g. 6d94fd30, 5216e781, 67b2e488
all touch both files). The functional code is identical between the
two; the only differences are comment verbosity and the path-filter
self-reference (each version watches its own location).

Removing the .github/ copy:
  - eliminates the dual-edit maintenance tax (two files touched per fix)
  - prevents accidental drift where one is updated and the other isn't
  - leaves a single source-of-truth at .gitea/workflows/

Cross-references confirmed safe:
  - canary-verify.yml + redeploy-tenants-on-{staging,main}.yml all use
    `workflows: ['publish-workspace-server-image']` (workflow name,
    not file path) — they trigger off the workflow_run event keyed on
    `name:`, which is identical in both files.
  - No other workflow path-watches .github/workflows/publish-workspace-
    server-image.yml.

Other two triplicates from task #287 (publish-runtime.yml and
secret-scan.yml) are NOT addressed in this PR — see PR description for
the ambiguity report flagging them for human review.

First-ever publish-runtime.yml dispatch (run 5097 post-#353, 2026-05-11
02:06Z) failed at the twine upload step:

  ERROR InvalidDistribution: Cannot find file (or expand pattern): 'dist/*'

Cause: the Publish step was missing 'working-directory: ${{ runner.temp
}}/runtime-build' while the preceding Build/Verify steps all had it.
Result: twine ran from the workspace checkout dir where dist/ doesn't
exist.

Fix: add working-directory to match the rest of the publish job.

This is the second of three workflow defects exposed by #353 finally
making the workflow run at all:
  1. workflow_dispatch.inputs rejection      → fixed in #353
  2. Publish step missing working-directory  → THIS PR
  3. (anything else surfaced by 0.1.130 attempt #2)

After merge: push runtime-v0.1.130 again (tag was already pushed once
post-#353 but the run failed at publish; need a fresh trigger). Should
finally land 0.1.130 on PyPI.

Run 5160 publish-runtime build step failed:

  error: TOP_LEVEL_MODULES drifted from workspace/*.py contents:
    in workspace/ but NOT in TOP_LEVEL_MODULES (will ship un-rewritten): ['_sanitize_a2a']
    Edit scripts/build_runtime_package.py:TOP_LEVEL_MODULES to match.

workspace/_sanitize_a2a.py was added recently but the allowlist in
scripts/build_runtime_package.py was not updated. The build script
intentionally aborts (exit 3) when it detects the drift, because
shipping a module un-rewritten breaks the package's flat-layout import
contract.

Fix: add '_sanitize_a2a' to the set. Alphabetical order preserved
(it sorts before 'a2a_*').

Third workflow defect after #353 (workflow_dispatch.inputs parser) and
#355 (Publish step working-directory). After this lands, attempt #4 of
runtime-v0.1.130 should finally succeed.

Bug: a2a_response.py:197 returned Queued(method=method) without passing
delivery_mode, silently defaulting to "poll" for push-mode busy-queue
responses. Callers branching on v.delivery_mode would mis-identify push-mode
responses as poll-mode, causing wrong dispatch logic.

Fix: pass delivery_mode="push" explicitly in the push-mode branch.

Tests: add push_queued_full/notify/no_method fixtures and 4 test cases
asserting delivery_mode="push" for all three envelope shapes. Also add
adversarial {"queued": "yes"} and {"queued": False} → Malformed guards.

Incorporates valuable extra coverage from fullstack-engineer's PR #336:
- test_push_queued_missing_queue_id_still_parsed: queue_id is optional,
  absence must not break parsing
- test_push_queued_is_distinct_from_poll_queued: both envelope shapes
  parse correctly and independently, with correct delivery_mode values

Also adds push_queued_no_queue_id fixture and regression gate entry.

Close the A2A delegation auto-resume gap.

Root cause: heartbeat.py's _check_delegations already writes completed
delegation rows to DELEGATION_RESULTS_FILE and sends a self-message to
wake the agent. executor_helpers.read_delegation_results() was defined to
atomically consume that file, but a2a_executor._core_execute() never
called it — so delegation results were written but the agent never saw
them.

Fix: call read_delegation_results() at the top of _core_execute() and
prepend the results to the user input context so the agent can act on
them without an explicit check_task_status call. The Temporal durable
workflow path is also covered because it calls _core_execute() directly.

Test: two new cases — delegation results injected when file exists;
user input passed through unchanged when file is empty.

Closes molecule-core#354.

fix(docker-compose): remove duplicate service definitions across include:
Secret scan / Scan diff for credential-shaped strings (pull_request) Successful in 12s
sop-tier-check / tier-check (pull_request) Failing after 10s
c7d3f1345e
docker-compose.yml added `include: docker-compose.infra.yml` (commit 8cd52fc6)
to bootstrap infra services, but the duplicate postgres/redis/langfuse-db-init
definitions were NOT removed from the main file. Docker Compose v2 errors
out on duplicate service definitions between an include: directive and the
main file, so `docker compose build` currently fails with:

  services.langfuse-db-init conflicts with imported resource

Fix (per issue #377):
- docker-compose.yml: drop the now-redundant postgres, redis,
  langfuse-db-init, langfuse-clickhouse service definitions (SSOT is
  docker-compose.infra.yml via include:)
- docker-compose.infra.yml: add missing `networks: - molecule-core-net` and
  `restart: unless-stopped` to postgres/redis/langfuse-clickhouse so the
  services are fully configured when imported
- docker-compose.infra.yml: rename `clickhouse` → `langfuse-clickhouse`
  to match the service name already used in docker-compose.yml's langfuse
  service environment/depends_on blocks

When GITHUB_APP_ID/INSTALLATION_ID are unset (post org suspension or
Gitea-canonical deployments without GitHub App), the fallback path in
GetInstallationToken was returning 500 Internal Server Error. This pollutes
platform logs with ~28×false-positive 500s/hour across all workspaces.

Return 501 Not Implemented with {"error":"GitHub integration not
configured","scm":"gitea"} when the "required" error fires — callers
can now distinguish "feature off" from "transient error" and stop polling.

Update TestGitHubToken_NoTokenProvider to assert the new 501 shape.

LGTM. The github_token.go fix correctly distinguishes "feature off" (501 Not Implemented when GITHUB_APP_ID/INSTALLATION_ID are unset, e.g. post org suspension or Gitea-canonical deployments) from "transient error" (500 for other failures like network). The test update is thorough. The docker-compose changes here apply the same deduplication fix as PR #385 but target staging — no conflict with the main-path PR.

[core-security-agent] N/A — non-security-touching

Platform error-response fix (github_token.go:501 vs 500 when GitHub integration unconfigured) + new publish-runtime-autobump workflow. /github-installation-token is behind AdminAuth + wsAuth. DISPATCH_TOKEN used only in git remote-set-url for tag push (standard CI pattern, token from secrets, not user-supplied). No security concerns.
