MECHANISM: Main is red because branch protection now requires the E2E Peer Visibility (literal MCP list_peers) / E2E Peer Visibility context, but the checked-in required-context allowlist was not updated. The lint job lint-no-coe-on-required cross-checks live branch protection against .gitea/required-contexts.txt; current main's allowlist only contains CI / all-required, E2E API Smoke Test / E2E API Smoke Test, and Handlers Postgres Integration / Handlers Postgres Integration (.gitea/required-contexts.txt:10). The peer-visibility workflow itself documents that the job is now required and emits the required job name (.gitea/workflows/e2e-peer-visibility.yml:80, :161).

EVIDENCE: molecule-core main run 358349, job 487203, head cd5f5898e0d383facee112e0dfe327435cd2bc5d. The failing log says branch-protection required contexts NOT in the checked-in allowlist and names E2E Peer Visibility (literal MCP list_peers) / E2E Peer Visibility. The recent merge stack includes #2730/#2731 but no allowlist update; the live status for main also shows the peer-visibility local job skipped, which is expected for the non-required local context and not the cause.

RECOMMENDED FIX SHAPE: Update molecule-core .gitea/required-contexts.txt to include exactly E2E Peer Visibility (literal MCP list_peers) / E2E Peer Visibility, keeping the local context E2E Peer Visibility (local) out of the allowlist because the workflow comments mark it non-required. Re-run python3 .gitea/scripts/lint_no_coe_on_required.py / CI to confirm the BP allowlist matches live branch protection.

The lint job `lint-no-coe-on-required` cross-checks live branch protection against `.gitea/required-contexts.txt`; current main's allowlist only contains `CI / all-required`, `E2E API Smoke Test / E2E API Smoke Test`, and `Handlers Postgres Integration / Handlers Postgres Integration` (`.gitea/required-contexts.txt:10`). The peer-visibility workflow itself documents that the job is now required and emits the required job name (`.gitea/workflows/e2e-peer-visibility.yml:80`, `:161`).

RCA tick follow-up (2026-06-13): current main 1f1a6f3d13ada032137ca12296ee87b4e7422897 now includes the required-context allowlist entry E2E Peer Visibility (literal MCP list_peers) / E2E Peer Visibility in .gitea/required-contexts.txt. The workflow still emits the required job as .gitea/workflows/e2e-peer-visibility.yml job E2E Peer Visibility.

Current main CI is pending but progressing normally, not red: Platform (Go), Shellcheck, and Python Lint & Test are green; Canvas (Next.js), Canvas tabs E2E, and image build are actively in progress. No new #2732-class blocker surfaced in this tick.

RCA tick follow-up (2026-06-13): inbox polling is unavailable in this runtime, so I audited current main status directly.

MECHANISM: no active incident found. molecule-core main 329eae8dc13c4ac1faab076012059855530ac871 is pending only because long-tail E2E jobs are actively running: E2E Peer Visibility is in workspace-online wait, and Local Provision Lifecycle E2E (real image + MiniMax LLM, advisory) reached restart-survival. molecule-controlplane main remains green.

EVIDENCE: run 358464 job 487419 progressed through tenant health and workspace provisioning; run 358473 job 487441 reached --- Step 4: restart-survival. The #2732 required-context allowlist entry remains present on main.

RECOMMENDED FIX SHAPE: none for this tick. Keep watching the two running jobs; file a fresh RCA only if one completes red with a concrete mechanism.

MECHANISM: no active incident found. molecule-core main 552c72d19def70809ec65838ab743bebda90005c is pending because post-merge push jobs are actively running: Canvas Next.js, Canvas tabs E2E, E2E Chat, publish-workspace-server image build, local-provision real-image advisory, and canvas-image promotion.

Resolved — fixed by #2733 (merged). Root cause exactly as diagnosed: the #1296 BP flip added the required E2E Peer Visibility (literal MCP list_peers) / E2E Peer Visibility context to branch_protections/main but not to the checked-in allowlist .gitea/required-contexts.txt, and lint_no_coe_on_required live-cross-checks the two.

#2733 added the 4th allowlist line; it merged through the full SOP gate (CR2 + qa-review + security-review + gate-check-v3 green). lint-no-coe-on-required (push) is now green on current main 0ebfb5d2.

Durable lesson (SSOT): flipping a status context to REQUIRED on core needs TWO SSOTs synced — branch_protections/main.status_check_contexts AND .gitea/required-contexts.txt (form <workflow name> / <job name>, event stripped). Best practice: include the allowlist line in the SAME PR that makes the gate required-ready, or merge the allowlist change before the BP PATCH, to avoid a transient main-red window. The #1296 checklist predated this guard (file Verified 2026-06-10) so didn't list it; worth adding to the flip-to-required runbook. Closing.

RCA tick follow-up (2026-06-13): no active red found after the #2740 merge wave. Current molecule-core main 65cdda1219e2c6c90b9229f3cca4cd9d12565dd6 is pending only on actively running push jobs: Canvas Next.js, E2E Chat, Canvas tabs E2E, workspace-server image build, and canvas-image promotion. Detect/Go/Shellcheck/Python and canvas image build have already completed green. molecule-controlplane and landingpage main remain green.

RECOMMENDED FIX SHAPE: none for this tick; continue watching for completion and keep #2739 routed separately for the earlier local-provision real-image red.
