-"""Live-fire regression test for #2159 — gate auto-fire runtime verification.
-
-Static tests (test_gate_review_auto_fire.py) validate that the workflow YAML
-is structurally correct. This test validates the *runtime* path: submitting an
-APPROVED review to a PR whose head contains the current gate workflows causes
-Gitea Actions to queue the qa-review + security-review workflows and POST the
-branch-protection-required (pull_request_target) contexts within a reasonable
-window.
-
-Skipped when Gitea API credentials are not available. Intended for:
-  - manual developer verification
-  - CI jobs provisioned with a service-account token
-
-Environment:
-  GITEA_HOST            — default: git.moleculesai.app
-  GITEA_TOKEN           — token with read:repository + write:issues (for review POST)
-  REPO                  — default: molecule-ai/molecule-core
-  LIVEFIRE_PR_NUMBER    — optional; if omitted the test tries to find a
-                          suitable open PR automatically, or skips.

-  #
-  # The REAL-boot complement to the deterministic unit suite
-  # (workspace_provision_platform_boot_test.go). Provisions a REAL staging
-  # claude-code workspace on the PLATFORM-managed path — provider=platform,
-  # model=moonshot/kimi-k2.6, NO tenant LLM key — and asserts it reaches
-  # status=online (NOT not_configured) and a completion returns 200, via the same
-  # online-wait + completion-assert the BYOK job uses.
-  #
-  # Why a SEPARATE job (not a matrix leg of e2e-staging-saas): the platform path
-  # injects NO secret and pins a different model, so its env block diverges from
-  # the BYOK job's. A dedicated job keeps each path's "verify key present" preflight
-  # honest (BYOK requires a key; platform requires its ABSENCE not to matter) and
-  # gives the regression its own named commit-status for branch protection.
-  #
-  # Add `E2E Staging Platform Boot` to branch protection after 3 consecutive
-  # green runs on main (de-flake window; this path shares the cp#245
-  # boot-timeout flake surface the BYOK job has, so it must prove stable before
-  # it can BLOCK — see the gate-making plan in the PR body).

-      #   The defense-in-depth half of this fix changes that redeploy

-      #   after `wait-ci` (green main CI), the canary-first batched fleet

-      #   `docker pull`, a redeploy that somehow still resolves "latest")
-      #   gets the blessed image instead of whatever happened to build.

-/**
- * Staging canvas E2E — REAL desktop take-control path (core#2261 "Gap 1").
- *
- * This is the live-e2e gate that the existing staging-tabs.spec.ts does NOT
- * provide. staging-tabs only opens the 13 declared workspace-panel tabs
- * (TAB_IDS at staging-tabs.spec.ts:24-38 — `display` is NOT among them) and
- * asserts they render without a "Failed to load" toast. It never acquires
- * display control, never opens the noVNC WebSocket, and never asserts a
- * framebuffer frame arrives. The companion unit test
- * canvas/src/components/tabs/__tests__/DisplayTab.test.tsx mocks the RFB
- * constructor (vi.mock("@novnc/novnc"), see its lines 8/20-39) so NO real
- * WebSocket is ever opened there either. Result: a broken take-control path
- * (acquire → noVNC WS upgrade → ws-proxy → EIC → websockify → x11vnc → Xvfb)
- * ships GREEN. This spec closes that gap by exercising the REAL wire path
- * end to end against a live, desktop-capable staging workspace.
- *
- * What it asserts (the real path, no mocks):
- *   1. POST /workspaces/<id>/display/control/acquire returns 200 with a
- *      session_url that carries the signed token in its `#token=` fragment
- *      (mirrors workspace_display_control.go:signedDisplaySessionURL).
- *   2. Opening the noVNC WebSocket at session_url with the subprotocols
- *      ["binary", "molecule-display-token.<token>"] (exactly what the canvas
- *      sends — DisplayTab.tsx:339) UPGRADES (onopen fires, readyState===OPEN,
- *      no immediate 1006 abnormal close). A 1006 / 403 means the handshake
- *      failed somewhere in the proxy chain.
- *   3. At least one BINARY framebuffer message arrives on that socket — a
- *      real frame off x11vnc, not just a panel mount. RFB sends a
- *      ProtocolVersion banner ("RFB 003.00x\n") as the first server message,
- *      which proves the upstream VNC server is live behind the EIC tunnel.
- *
- * Auth model (important): the WS upgrade is gated by workspace-server
- * middleware.AdminAuth. A browser WebSocket CANNOT set an Authorization
- * header, so in production the canvas WS upgrade passes AdminAuth via the
- * same-origin-canvas path (wsauth_middleware.go:isSameOriginCanvas, which
- * keys off the Origin header the browser sets automatically on a same-origin
- * WS upgrade). We therefore open the socket from inside the browser page via
- * page.evaluate AFTER navigating to the tenant origin — so the browser sends
- * `Origin: https://<slug>.staging.moleculesai.app`, exactly as production
- * does. The acquire POST (which CAN carry a header) uses the per-tenant admin
- * bearer set on the context. This is the faithful production handshake, not a
- * synthetic one.
- *
- * Gate / cost: this test only runs when STAGING_DISPLAY_WORKSPACE_ID points
- * at a STANDING desktop-capable workspace (compute.display.mode ==
- * "desktop-control"). We deliberately do NOT provision one in the shared
- * staging-setup.ts: a desktop AMI boots in ~12-15 min and would tax the
- * existing tabs harness on every run. Standing that workspace up is a cost
- * item for the CTO (one always-on desktop EC2 on staging). Until that exists,
- * the test SKIPS loud. When the env IS present, any failure in
- * provision/acquire/upgrade is a HARD error — fail-closed, never silently
- * green (no "flaky" disposition: a 1006 names a broken proxy hop).

- * PROMOTION-READINESS — staging canvas E2E → HARD merge-gate
- * ----------------------------------------------------------
- * NOW RELIABLE (deterministic; these no longer flap on timing):
- *   - Every wait is condition-based (toBeVisible / toHaveAttribute /
- *     expect.poll). There is NO fixed waitForTimeout / sleep in the spec;
- *     the only setTimeout is the bounded poll-interval inside
- *     staging-setup.ts waitFor(), which has a hard deadline.
- *   - Tabs are asserted on REAL settled content (non-empty, non-spinner),
- *     not just "container is visible" — an empty or stuck-loading panel now
- *     fails instead of shipping green.
- *   - The ErrorBoundary ("Something went wrong") is asserted absent at app
- *     hydration AND per tab — a React subtree crash can no longer pass.
- *   - Visible error alerts inside a panel fail non-degraded tabs (was a
- *     weak [role=alert]:has-text("Failed to load")-only check that missed
- *     both other error phrasings and role-less error divs).
- *   - The driven tab list is parity-checked against the live DOM, so a new
- *     SidePanel tab can't ship un-tested and a removed one fails loud.
- *   - Click→activation is confirmed (aria-selected) before asserting the
- *     panel, removing a wrong-panel race.
- *   - The suite is fail-closed: CANVAS_E2E_STAGING=1 with no tenant state
- *     hard-errors (never skips→green); CANVAS_E2E_STAGING unset cleanly
- *     skips (operator did not request staging).
- *
- * STILL BLOCKS PROMOTION-TO-REQUIRED (do NOT flip continue-on-error here —
- * CTO-owned, RFC internal#219 §1):
- *   - INFRA DEPENDENCY: each run provisions a real staging EC2 tenant
- *     (12-20 min cold boot). Required-gate latency + AWS/Cloudflare/CP
- *     availability become merge-blockers. A staging outage would freeze
- *     main even though the code is fine — unacceptable for a required check
- *     until staging has an SLA or this runs against a warm pre-provisioned
- *     pool.
- *   - SHARED-RESOURCE FLAKE SURFACE: TLS/DNS/ACME propagation on a shared
- *     staging zone (staging-setup TLS_TIMEOUT_MS) is outside this repo's
- *     control. Deterministic here ≠ deterministic upstream.
- *   - SECRET DEPENDENCY: CP_STAGING_ADMIN_API_TOKEN must be present on the
- *     runner. The workflow's skip-if-absent (core#2225) keeps a missing
- *     secret from painting red — correct for non-gating, but a REQUIRED
- *     check must instead guarantee the secret is always present, else it
- *     skip-greens the very thing it is supposed to enforce.
- *   - SINGLE-WORKSPACE COVERAGE: one hermes/platform_managed workspace that
- *     does NOT boot an agent on staging (no CP LLM proxy env, workspace-
- *     server #2162). Tabs render, but agent-dependent content paths (live
- *     chat round-trip, traces from a real run) are not exercised.
- *
- * PROMOTION CHECKLIST (when CTO signs off on making this required):
- *   1. Warm pre-provisioned tenant pool OR a staging SLA bounding boot time.
- *   2. Guarantee CP_STAGING_ADMIN_API_TOKEN on the gating runner; turn the
- *      skip-if-absent into a hard error for the required path.
- *   3. Decide whether agent-dependent tabs need a wired LLM proxy on the
- *      staging tenant (covers chat/traces real content) before gating them.

-# Developer SOP — PR review gate auto-fire and stale-head handling
-
-> Last updated: 2026-06-03 (cp#2159 follow-up)
->
-> Applies to: all core-PR authors and reviewers on `molecule-core` and sibling
-> repos using the `qa-review` + `security-review` branch-protection gates.
-
----
-
-## 1. Gitea PR-head workflow-selection rule
-
-**Rule:** For `pull_request_target` and `pull_request_review` events, Gitea
-loads the workflow definition from the **PR's HEAD branch**, not from the
-base (`main`) branch.
-
-This is different from GitHub Actions, where `pull_request_target` always
-loads workflows from the base branch. Gitea's behaviour means:
-
-- A PR that was opened **before** the `pull_request_review` trigger was added
-to `qa-review.yml` / `security-review.yml` will **NOT** auto-fire on review,
-because its HEAD still contains the old workflow YAML (no trigger).
-
-- A PR that was opened **after** the trigger was added (or that has been
-rebased onto a commit containing the trigger) **WILL** auto-fire, because its
-HEAD contains the new workflow YAML.
-
-### Ops implication
-
-| PR head contains `pull_request_review` trigger? | Behaviour on APPROVED review |
-|---|---|
-| **Yes** (cut from current main, or rebased) | Workflows auto-queue, evaluate, and POST the `(pull_request_target)` context automatically. No slash-command needed. |
-| **No** (stale head, opened before #2157) | Nothing fires. Use `/qa-recheck` + `/security-recheck` slash-commands in a PR comment, OR rebase onto current main. |
-
----
-
-## 2. Standard core-PR flow (post-#2157)
-
-```
-1. Author opens PR from a branch based on current main
-   → qa-review + security-review workflows run on pull_request_target
-   → status contexts post (initial eval, usually red until reviews land)
-
-2. Reviewers submit real APPROVED reviews
-   → If PR head has the trigger: workflows AUTO-FIRE on pull_request_review
-   → Contexts flip green (or stay red if reviewer is not in team)
-
-3. [Optional] If contexts did not flip (stale head, event lost, etc.):
-   → Anyone can comment `/qa-recheck` or `/security-recheck`
-   → sop-checklist.yml refires the evaluator (read-only, idempotent)
-
-4. Both qa-review + security-review contexts are green
-   → Plain Do:merge (no force-merge needed)
-```
-
-### Key point
-
-The `/qa-recheck` and `/security-recheck` commands are a **backstop**, not the
-primary path. PRs cut from current main should auto-fire without manual
-intervention.
-
----
-
-## 3. Diagnosing a stale head
-
-If a PR has real team-member APPROVED reviews but the qa/security contexts
-remain red and no workflow run appears on the PR's "Actions" tab for the
-review event, the PR head is likely stale.
-
-### Quick check
-
-```bash
-# From the PR page, look at the head commit SHA, then:
-curl -sS "https://git.moleculesai.app/api/v1/repos/molecule-ai/molecule-core/contents/.gitea/workflows/qa-review.yml?ref=<HEAD_SHA>" \
-  | jq -r '.content' | base64 -d | grep -c 'pull_request_review'
-# 0  → stale head (no trigger in that version of the workflow)
-# >0 → trigger present; auto-fire SHOULD work (if it didn't, file a tracker)
-```
-
-### Automated diagnostic
-
-The test suite includes `test_gate_stale_head_diagnostic.py`, which reports
-"auto-fire impossible for this PR" when the head lacks the trigger. Run it
-in CI or locally with:
-
-```bash
-PR_NUMBER=123 python -m pytest .gitea/scripts/tests/test_gate_stale_head_diagnostic.py -v
-```
-
----
-
-## 4. Rebasing vs. slash-refire
-
-| Approach | When to use | Trade-off |
-|---|---|---|
-| **Rebase onto current main** | PR is genuinely stale (head lacks trigger OR head is far behind main) | Clean history, gets all recent fixes, but requires force-push and re-approval if the branch was protected |
-| **`/qa-recheck` + `/security-recheck`** | PR head is recent but the review event was missed, or you want to avoid rebase churn | Quick, no force-push, but does NOT fix a missing trigger in the head |
-
-**Do not** use slash-refire as a substitute for rebasing a stale head. If the
-workflow YAML in the PR head does not contain `pull_request_review`, no amount
-of rechecking will make auto-fire work.
-
----
-
-## 5. Live-fire verification
-
-The `test_gate_auto_fire_live.py` regression test exercises the full runtime
-path: it submits an APPROVED review to a test PR and polls for the
-`(pull_request_target)` status contexts. It is skipped when no API token is
-available, and is intended to catch runtime non-fire that static structural
-tests (e.g. `test_gate_review_auto_fire.py`) cannot detect.
-
-Run manually with:
-
-```bash
-export GITEA_HOST=git.moleculesai.app
-export GITEA_TOKEN=<your-token>
-export REPO=molecule-ai/molecule-core
-export LIVEFIRE_PR_NUMBER=<test-pr-number>
-python -m pytest .gitea/scripts/tests/test_gate_auto_fire_live.py -v
-```

-#!/usr/bin/env bash
-# Live staging E2E — the CP instance-state reconciler heals a terminated EC2.
-#
-# Real-infra complement to the deterministic unit tests for core#2261
-# (workspace-server/internal/registry/cp_instance_reconciler.go). Those unit
-# tests pin the reconcile logic against fakes; THIS script proves the loop
-# actually runs in a real tenant's workspace-server and drives the EXISTING
-# offline + auto-heal machinery against real AWS.
-#
-# Root regression (core#2247): a SaaS workspace whose EC2 is terminated out
-# from under the platform (manual AWS action, spot reclaim, CP reap) fell
-# through every existing liveness pass and kept reading status='online'
-# forever, pointing at a dead instance. The reconciler closes that gap with
-# CPProvisioner.IsRunning and feeds a clean "not running" into onOffline →
-# RestartByID (existing-volume reprovision).
-#
-# What this test does:
-#   1. Provision a fresh staging org + ONE workspace (same default
-#      runtime/model as the full-saas harness, so it actually boots).
-#   2. Poll the tenant API until the workspace is status=online; capture its
-#      instance_id.
-#   3. KILL it — terminate that exact EC2 via `aws ec2 terminate-instances`.
-#   4. Assert the reconciler heals it:
-#        PRIMARY (gate)      — within ~180s the workspace status LEAVES
-#                              'online' (the reconciler detected the dead
-#                              instance via IsRunning and flipped it). This
-#                              is the core regression guard: a dead instance
-#                              must NOT keep reading 'online'.
-#        SECONDARY (best-effort) — within ~10 min it auto-reprovisions:
-#                              status returns to 'online' with a NEW
-#                              instance_id (onOffline → RestartByID
-#                              existing-volume heal). If reprovision doesn't
-#                              finish in the bound we log it clearly but let
-#                              the PRIMARY assertion stand as the gate (see
-#                              the comment at the secondary block — a future
-#                              tightening that promotes this to a hard gate is
-#                              deliberately one edit away).
-#   5. Teardown ALWAYS (EXIT trap): delete the tenant + leak-sweep so no EC2
-#      is orphaned, even on a mid-test failure.
-#
-# Auth model + provisioning conventions are copied verbatim from
-# test_staging_full_saas.sh (single MOLECULE_ADMIN_TOKEN → CP admin; per-
-# tenant admin token + X-Molecule-Org-Id header for tenant API). The kill
-# primitive + leak sweep reuse lib/aws_leak_check.sh.
-#
-# Required env:
-#   MOLECULE_CP_URL        default: https://staging-api.moleculesai.app
-#   MOLECULE_ADMIN_TOKEN   CP admin bearer — Railway staging CP_ADMIN_API_TOKEN

-#   E2E_PROVISION_TIMEOUT_SECS         default 900 (cold EC2 budget)
-#   E2E_WORKSPACE_ONLINE_TIMEOUT_SECS  default 900 (15min). A workspace that
-#                     cannot reach online in 15min is a staging/boot problem,
-#                     not slow cold-boot — fail fast so the trap tears down the
-#                     EC2 instead of hanging ~1h and leaking a running instance
-#                     (observed: run 216031 hung 32min with a live e2e-rec EC2).

-// activity_seq_backfill_integration_test.go — REAL Postgres proof of the
-// invariant the 20260604000000_activity_logs_seq.up.sql migration guarantees:
-// every activity_logs row carries a NON-NULL `seq`, both for rows that existed
-// before the migration ran (assigned during the ALTER TABLE rewrite) and for
-// rows created afterward via the normal INSERT path (assigned by the IDENTITY
-// default). This is the coverage CR2 (#2339 review) correctly flagged as
-// missing on PR #2258.
-//
-// WHY THIS IS A SEPARATE TEST from activity_since_id_ordering_integration_test.go:
-// that test pins the *ordering* contract (same-microsecond rows come back in a
-// deterministic (created_at, seq) order). THIS test pins the *backfill* contract
-// — that `seq` is never NULL — and the consequence the reviewer doubted: a
-// pre-existing/backfilled row is usable as a since_id cursor because its seq is
-// non-null, so the tuple cursor `(created_at, seq)` the handler builds is well
-// defined for it.
-//
-// EMPIRICAL BASIS (PostgreSQL 16.13, the prod PG version):
-//   - `ALTER TABLE activity_logs ADD COLUMN seq BIGINT GENERATED BY DEFAULT AS
-//     IDENTITY` rewrites the table and assigns seq to EXISTING rows in physical
-//     table-scan order — they are NON-NULL, not left NULL as the review claimed.
-//   - The identity sequence then advances ABOVE max(seq), so the next INSERT
-//     that omits seq gets max+1 with no collision.
-// Run against any Postgres 15/16 the integration harness boots — the property
-// holds on both.
-//
-// Run with (same harness as activity_delegation_a2a_integration_test.go):
-//
-//	docker run --rm -d --name pg-integration \

-//	  go test -tags=integration ./internal/handlers/ -run Integration_ActivityLogs_Seq
-//
-// WATCH-IT-FAIL: if `seq` were left nullable / un-backfilled (the failure mode
-// the reviewer hypothesized), the NULL-count assertion in _NoNull trips, and
-// the since_id-on-a-backfilled-row case in _SinceIDOnBackfilledRow trips because
-// the handler cannot read a non-null seq for the cursor row. With the migration

-// workspace_provision_platform_boot_test.go — the deterministic, SSOT-driven
-// regression suite for the class of bug behind the moonshot/kimi
-// "canvas-created claude-code workspace boots NOT_CONFIGURED" production
-// incident (RFC#340 Fix A #2187, canvas Fix C #2188).
-//
-// THE BUG (what shipped to prod):
-//   A claude-code workspace created via the canvas with provider=Platform +
-//   model="moonshot/kimi-k2.6" booted NOT_CONFIGURED. Unit tests passed; the
-//   REAL boot path was broken. ensureDefaultConfig generated a config.yaml that
-//   carried NO derived `provider:` key, so the cp#329 config-bundle the adapter
-//   actually reads left molecule-runtime config.py to slash-split the model id
-//   "moonshot/kimi-k2.6" -> provider="moonshot", which is NOT in the providers
-//   registry -> NOT_CONFIGURED.
-//
-// THE FIX A INVARIANT (this file pins it, and pins it for the WHOLE class):
-//   ensureDefaultConfig MUST stamp the manifest-derived provider into the
-//   generated config.yaml — at BOTH the top level and under runtime_config —
-//   for every (runtime, model) the providers SSOT maps to a platform provider.
-//   The single-combo pin (TestEnsureDefaultConfig_StampsDerivedProvider in
-//   workspace_provision_test.go) proves the headline case. THIS file closes the
-//   gap that single pin leaves: it is PARAMETRIZED OVER THE SSOT, so when a NEW
-//   platform model is added to providers.yaml for claude-code (or any runtime
-//   with a platform arm), the new id is automatically covered — a future
-//   platform model that fails to derive `provider: platform` fails THIS test at
-//   build time, before it can ship a NOT_CONFIGURED boot.
-//
-// WHY SSOT-DRIVEN AND NOT A HAND-MAINTAINED LIST:
-//   The original bug was a divergence between "what the canvas offers"
-//   (providers.yaml platform arm) and "what the config generator stamps". A
-//   hardcoded test model list would itself drift from the SSOT and re-open the
-//   same divergence gap. By enumerating the platform model set directly from the
-//   loaded providers.Manifest (the SAME manifest ensureDefaultConfig's
-//   deriveDefaultConfigProvider resolves against), this test cannot fall behind
-//   the offered set: add a platform model, get a test case for free; the test
-//   only passes if the generator actually stamps it.
-//
-// SCOPE: deterministic, no live infra. The REAL-boot complement (provision a
-// staging workspace and assert status=online + a completion returns 200 for the
-// SAME combo) is the bash staging harness — see
-// tests/e2e/test_staging_full_saas.sh (E2E_LLM_PATH=platform) and the
-// e2e-staging-platform-boot job in .gitea/workflows/e2e-staging-saas.yml. That
-// asserts the REAL artifact (booted status / completion); THIS asserts the
-// deterministic config-generation invariant the real boot depends on.
