test(workspace): add 36-case coverage for shared_runtime helpers (closes #366 )

Six helper functions previously had zero test coverage: | Function | Cases | |----------|-------| | `_extract_part_text` | 10 — dict/object/root nesting, None, unexpected types | | `extract_message_text` | 6 — parts list, context objects, whitespace | | `format_conversation_history` | 4 — user/agent roles, interleaved history | | `build_task_text` | 4 — history prepending, empty history | | `append_peer_guidance` | 6 — base text, None/empty/whitespace, empty peers | | `brief_task` | 6 — limit variants including 0/1 edge cases | Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
fix(a2a): restore OFFSEC-003 trust-boundary wrap on tool_delegate_task return (closes #491 ) (#492 )

The heartbeat delegation-polling path queries activity_logs WHERE method IN ('delegate','delegate_result'), so these rows are invisible — delegation results never surface to the callers. This change adds logA2ADelegationResult which writes the correct activity_type='delegation' + method='delegate_result' row, and wires it into proxyA2ARequest when the proxied method is 'delegate_result'. The ListDelegations handler already serves these rows, so the heartbeat picks them up without any Python-side changes.

fullstack-engineer	72a48214ee	fix(platform): close CWE-59 symlink-traversal gap in resolveInsideRoot (#380 ) sop-tier-check / tier-check (pull_request) Failing after 5s Details Secret scan / Scan diff for credential-shaped strings (pull_request) Successful in 6s Details audit-force-merge / audit (pull_request) Successful in 30s Details Follow-up to #369. `resolveInsideRoot` used `filepath.Abs` which does NOT resolve symlinks — so "workspaces/dev/leaked" where "leaked" is a symlink to "/etc" would lexically pass the prefix check but resolve outside root. Fix: call `filepath.EvalSymlinks` before the final prefix check. If the resolved path points outside root the function returns "path escapes root". Broken symlinks are also rejected (fail closed). Also add TestResolveInsideRoot_RejectsSymlinkTraversal covering: - Symlink pointing outside → rejected (CWE-59) - Symlink staying inside root → allowed - Broken symlink → rejected	2026-05-11 06:26:56 +00:00

Return HTTP 501 Not Implemented with scm:"gitea" so the workspace credential helper distinguishes "not configured" (stop retrying) from "provider failed" (retry with back-off). The 501 body is intentionally compatible with the scm:"gitea" shape already used elsewhere in the platform so callers can branch on SCM type.	2026-05-11 06:21:02 +00:00
infra-runtime-be	b1e42ac1da	fix(workspace): skip idle prompt when delegation results are pending sop-tier-check / tier-check (pull_request) Failing after 7s Details Secret scan / Scan diff for credential-shaped strings (pull_request) Successful in 9s Details Secret scan / Scan diff for credential-shaped strings (push) Successful in 36s Details audit-force-merge / audit (pull_request) Has been skipped Details Issue #381: agent tick generators producing stale-repo state. Root cause: the idle loop fires every idle_interval_seconds (default 10 min) and sends an idle prompt regardless of pending delegation results. If a delegation completes just before the idle tick fires, the heartbeat writes results to DELEGATION_RESULTS_FILE and sends a self-message — but the idle prompt arrives first and the agent composes a stale tick before processing the results notification. Peers receive repeated identical asks. Fix: before sending the idle prompt, read DELEGATION_RESULTS_FILE. If it contains unconsumed results, skip this idle tick. The heartbeat's own self-message (sent when results arrive) will wake the agent, which then sees the results in _prepare_prompt() and processes them before composing. Companion to wsr PR (runtime-runtime mirror).
