test(workspace): add 39-case coverage for shared_runtime helper functions

Add comprehensive tests for the 6 remaining untested helpers in shared_runtime.py: - _extract_part_text: 10 cases covering dict, object, root nesting - extract_message_text: 6 cases for parts extraction and context objects - format_conversation_history: 4 cases for role formatting - build_task_text: 4 cases for history prepending - append_peer_guidance: 5 cases for peer info injection - brief_task: 6 cases for truncation Net new: 39 tests for previously zero-covered helpers. 🤖 Generated with Claude Code Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
fix(canvas): repair 31 failing vitest tests (closes #344 )

-# Auto-bump-on-workspace-edit half of the publish pipeline.
-#
-# Why this file exists (issue #351):
-#   Gitea Actions does not correctly disambiguate `paths:` from `tags:`
-#   when both are bundled under a single `on.push` key. The result is
-#   that tag pushes get filtered out and `publish-runtime.yml` never
-#   fires — `action_run` rows: 0. This was unnoticed pre-2026-05-11
-#   because PYPI_TOKEN was absent (publishes would have failed anyway).
-#
-#   Split design:
-#     - publish-runtime.yml         : on.push.tags only        (the publisher)
-#     - publish-runtime-autobump.yml: on.push.branches+paths   (this file — the version-bumper)
-#
-#   This file computes the next version from PyPI's latest, pushes a
-#   `runtime-v$VERSION` tag, and exits. The tag push then triggers
-#   publish-runtime.yml via its tags-only trigger.
-#
-# Concurrency: shares the `publish-runtime` group with publish-runtime.yml
-# so concurrent workspace pushes serialize at the bump step. Without
-# this, two pushes minutes apart could both read PyPI latest=0.1.129
-# and try to tag 0.1.130 simultaneously, only one of which would land.

+      # Gitea (codex, crewai, deepagents, gemini-cli, langgraph) plus all
+      # 7 org-template-* repos are private. The pre-fix Dockerfile.tenant
+      # ran `git clone` inside an in-image stage, which had no auth path
+      # — every CI build failed with "fatal: could not read Username for
+      # https://git.moleculesai.app". For weeks, every workspace-server
+      # rebuild required a manual operator-host push. Now we clone in the
+      # trusted CI context (where AUTO_SYNC_TOKEN is naturally available)
+      # and Dockerfile.tenant just COPYs from .tenant-bundle-deps/.
+      #
+      # Token shape: AUTO_SYNC_TOKEN is the devops-engineer persona PAT
+      # (see /etc/molecule-bootstrap/agent-secrets.env). Per saved memory
+      # `feedback_per_agent_gitea_identity_default`, every CI surface uses
+      # a per-persona token, never the founder PAT. clone-manifest.sh
+      # embeds it as basic-auth (oauth2:<token>) for the duration of the
+      # clones, then strips .git directories — the token never enters
+      # the resulting image.
+      #
+      # Idempotent: if a re-run finds populated dirs, clone-manifest.sh
+      # skips them; safe to retrigger via path-filter or workflow_dispatch.

+      # Canary-gated release flow:
+      #   - This step always publishes :staging-<sha> + :staging-latest.
+      #   - On staging push, staging-CP picks up :staging-latest immediately
+      #     (its TENANT_IMAGE pin is :staging-latest) — so staging-branch
+      #     code reaches staging tenants without waiting for main.
+      #   - On main push, canary-verify.yml runs smoke tests against
+      #     canary tenants (which pin :staging-<sha>), and on green retags
+      #     :staging-<sha> → :latest. Prod tenants pull :latest.
+      #   - On red, :latest stays on the prior good digest — prod is safe.
+      #
+      # Why :staging-latest is retagged on main push too: when main lands
+      # after a staging promote, staging-CP gets the post-promote code so
+      # the canary-on-staging-CP step still runs against the prod-bound
+      # digest. In a healthy flow the post-promote main code == the
+      # current staging code, so this is effectively a no-op except for
+      # the canary fleet pin handoff.
+      #
+      # Pre-fix history: this workflow used to only trigger on main. That
+      # meant staging-CP served "yesterday's main" indefinitely whenever
+      # staging→main was wedged. The 2026-04-30 dogfooding session
+      # surfaced this when RFC #2312 (chat upload HTTP-forward) landed on
+      # staging but staging tenants kept failing chat upload because they
+      # were running pre-RFC code. Adding the staging trigger above closes
+      # that gap. Earlier 2026-04-24 incident: a static :staging-<sha> pin
+      # drifted 10 days behind staging — same class of bug, different

fullstack-engineer	d4d3306150	fix(workspace): inject plugins_registry into sys.modules before loading adapters (closes #296 ) sop-tier-check / tier-check (pull_request) Failing after 3s Details Secret scan / Scan diff for credential-shaped strings (pull_request) Failing after 58s Details audit-force-merge / audit (pull_request) Successful in 2s Details Plugin adapters in molecule-skill-* repos do: from plugins_registry.builtins import AgentskillsAdaptor as Adaptor But _load_module_from_path() used exec_module() with a fresh module namespace that did NOT have plugins_registry or its submodules in sys.modules, causing: ModuleNotFoundError: No module named 'plugins_registry' Fix: before exec_module(), import and register plugins_registry + all three submodules (builtins, protocol, raw_drop) in sys.modules so adapter imports resolve correctly. Follows the Option 1 recommendation from issue #296. Also adds test_resolve_plugin.py verifying the fix for both the AgentskillsAdaptor import and the full InstallContext/resolve/protocol import. Closes #296. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>	2026-05-10 14:17:16 +00:00

infra-lead	7ff5622a42	[infra-lead-agent] fix(ci): retry git clone in clone-manifest.sh (publish-workspace-server-image flake) Secret scan / Scan diff for credential-shaped strings (pull_request) Failing after 1s Details sop-tier-check / tier-check (pull_request) Failing after 1s Details audit-force-merge / audit (pull_request) Failing after 2s Details The publish-workspace-server-image / build-and-push job clones the full manifest (~36 repos) serially in the "Pre-clone manifest deps" step on a memory-constrained Gitea Actions runner. Under host memory pressure the OOM killer SIGKILLs git-remote-https mid-clone: cloning .../molecule-ai-plugin-molecule-skill-code-review.git ... error: git-remote-https died of signal 9 fatal: the remote end hung up unexpectedly ❌ Failure - Main Pre-clone manifest deps exitcode '128': failure Observed in run 4622 (2026-05-10, staging HEAD `b5d2ab88`) — died on the 14th of 36 clones, which red-lights CI and wedges staging→main. Wrap each `git clone` in clone-manifest.sh with bounded retry + backoff (3 attempts, 3s/6s), wiping any partial checkout between tries. A single transient SIGKILL / network blip no longer fails the whole tenant image rebuild. Benefits every caller of the script (publish-workspace-server-image, harness-replays, Dockerfile builds, local quickstart). This is a mitigation; the durable fix is more runner RAM/swap on the operator host — tracked separately with Infra-SRE.

fullstack-engineer	bea89ce4e9	fix(a2a): handle string-form errors in delegate_task Secret scan / Scan diff for credential-shaped strings (pull_request) Failing after 14s Details sop-tier-check / tier-check (pull_request) Failing after 7s Details audit-force-merge / audit (pull_request) Failing after 5s Details The A2A proxy can return three error shapes: {"error": "plain string"} {"error": {"message": "...", "code": ...}} {"error": {"message": {"nested": "object"}}} ← value at .message is a string builtin_tools/a2a_tools.py:72 called data["error"].get("message") without guarding against error being a string, which raised: AttributeError: 'str' object has no attribute 'get' This broke every delegation attempt through the legacy a2a_tools path (the LangChain-wrapped version used by adapter templates). The SSOT parser a2a_response.py already handled string errors; the legacy inline sniffer in a2a_tools.py did not. Fix: branch on isinstance(err, dict/str/other) before calling .get(). Also update both publish-workflow files to remove the dead `staging` branch trigger — trunk-based migration (PR #109, 2026-05-08) removed the staging branch.
