test(canvas): add form-inputs coverage (35 cases) + Section accessibility fix

+ form-inputs.test.tsx: 35 cases across TextInput, NumberInput, Toggle,
  TagList, and Section — pure presentational components in the Config tab.
  Uses vi.hoisted() patterns from established suite; no jest-dom matchers.

+ form-inputs.tsx (Section): add aria-expanded + aria-controls to the
  collapsible toggle button for WCAG 2.1 AA compliance. The content div
  gets a stable id derived from the title; aria-controls links button to
  region. Indicator span gains aria-hidden="true" (decorative only).

-"""lint-required-no-paths — structural enforcement of
-`feedback_path_filtered_workflow_cant_be_required`.
-
-For every workflow whose status-check context appears in
-`branch_protections/<branch>.status_check_contexts`, assert that the
-workflow's `on:` block has NO `paths:` and NO `paths-ignore:` filter.
-
-A required-check workflow with a paths filter silently degrades the
-merge gate:
-
-  - If the PR's diff doesn't match the `paths:` glob, the workflow
-    never fires.
-  - Gitea (1.22.6) reports the required context as `pending` (never as
-    `skipped == success`), so the PR cannot merge.
-  - For a docs-only PR against `paths: ['**.go']`, the PR is
-    blocked forever — no human action can produce a green.
-
-The class was previously prevented only by reviewer vigilance + the
-saved memory `feedback_path_filtered_workflow_cant_be_required`. This
-script makes it a hard CI gate so a future PR adding `paths:` to a
-required workflow fails fast at PR time, not after merge when the next
-docs PR wedges main.
-
-The lint runs as `.gitea/workflows/lint-required-no-paths.yml` on every
-PR. The lint workflow ITSELF must not have a paths-filter (otherwise it
-could be circumvented by a paths-non-matching PR) — that's enforced by
-self-reference and by the workflow's own `on:` block deliberately
-omitting filters.
-
-Sources of truth:
-  - `branch_protections/<branch>` `status_check_contexts` (the merge gate)
-  - `.gitea/workflows/*.yml` `name:` + `on:` (the workflow set)
-
-Context-format note (Gitea 1.22.6):
-  Status-check contexts are formatted `{workflow_name} / {job_name_or_key} ({event})`.
-  We parse the workflow_name prefix and walk `.gitea/workflows/*.yml` for
-  a file whose `name:` attr matches. (The filename is NOT the source of
-  truth; `name:` is, because Gitea formats the context from `name:`.)
-
-Exit codes:
-  0 — no required workflow has a paths/paths-ignore filter (clean) OR
-      branch_protections endpoint returned 403/404 (token-scope issue;
-      surfaced via ::error:: but non-fatal so a missing scope doesn't
-      red-X every PR — fix the token, not the lint).
-  1 — at least one required workflow has a paths/paths-ignore filter
-      (the gate-degrading defect class).
-  2 — env contract violation (missing GITEA_TOKEN/HOST/REPO/BRANCH).
-  3 — workflows directory missing or workflow YAML unparseable.
-  4 — protection response shape unexpected (non-dict body on 2xx).
-
-Auth note: `GET /repos/.../branch_protections/{branch}` requires
-repo-admin role in Gitea 1.22.6. The workflow-default `GITHUB_TOKEN`
-is non-admin; we re-use `DRIFT_BOT_TOKEN` (same persona that powers
-ci-required-drift.yml). If `DRIFT_BOT_TOKEN` is unavailable in a future
-context, the script falls through gracefully (exit 0 + ::error::).

-"""lint-workflow-yaml — catch Gitea-1.22.6-hostile workflow YAML shapes.
-
-This script enforces six structural rules that have historically caused
-silent CI failures on Gitea Actions (1.22.6) — workflows that the server's
-YAML parser rejects with `[W] ignore invalid workflow ...` and registers
-for zero events, or shape conventions that produce ambiguous status
-contexts. Each rule maps to a documented incident in saved memory.
-
-Rules (4 fatal + 1 fatal cross-file + 1 heuristic-warn):
-  1. `workflow_dispatch.inputs:` block — Gitea 1.22.6 mis-parses the
-     `inputs` keys as sibling event types and rejects the whole file.
-     Memory: feedback_gitea_workflow_dispatch_inputs_unsupported.
-     Origin: 2026-05-11 PyPI freeze (publish-runtime).
-  2. `on: workflow_run:` event — not enumerated in Gitea 1.22.6's
-     supported event list (verified via modules/actions/workflows.go
-     enumeration; task #81). Workflow registers, fires for 0 events.
-  3. `name:` containing `/` — breaks the
-     `<workflow> / <job> (<event>)` commit-status context convention;
-     downstream parsers (sop-tier-check, status-reaper) tokenize on `/`.
-  4. `name:` collision across files — Gitea routes commit-status updates
-     by `name` and behavior on collision is undefined (status-reaper
-     rev1 fail-loud).
-  5. Cross-repo `uses: org/repo/path@ref` — blocked while
-     `[actions].DEFAULT_ACTIONS_URL=github` is the server default;
-     resolves to github.com/<org-suspended>/... and 404s.
-     Memory: feedback_gitea_cross_repo_uses_blocked. Cross-link: task #109.
-  6. (HEURISTIC, warn-not-fail) Steps reference `https://api.github.com`
-     or `https://github.com/.../releases/download` without a
-     workflow-level `env.GITHUB_SERVER_URL` set to the Gitea instance.
-     Memory: feedback_act_runner_github_server_url.
-
-Per `feedback_smoke_test_vendor_truth_not_shape_match`: fixtures used to
-validate this lint must mirror real Gitea 1.22.6 YAML semantics, not
-Python yaml-parser quirks. The test suite at tests/test_lint_workflow_yaml.py
-includes a vendor-truth fixture (the exact publish-runtime regression).
-
-Usage:
-  python3 .gitea/scripts/lint-workflow-yaml.py
-    Lint every `*.yml` in `.gitea/workflows/`.
-
-  python3 .gitea/scripts/lint-workflow-yaml.py --workflow-dir <path>
-    Lint a custom directory (used by tests/test_lint_workflow_yaml.py).
-
-Exit codes:
-  0 — clean OR only heuristic-warnings emitted.
-  1 — at least one fatal rule (1-5) violated.
-  2 — YAML parse error or argv usage error.

-
-Rule
-----
-For a given protected branch, every context in
-`branch_protections/<branch>.status_check_contexts` MUST be emitted
-by at least one workflow in `.gitea/workflows/*.yml`. Two contexts
-match when:
-
-  1. The workflow's `name:` equals the context's workflow-part (the
-     prefix before ` / `).
-  2. Some job in that workflow has a `name:` (or default-fallback
-     job-key) equal to the context's job-part (between ` / ` and
-     ` (`).
-  3. The workflow's `on:` block includes the context's event-part
-     (in parens at the end), with Gitea's event-name mapping:
-        - `pull_request` and `pull_request_target` BOTH emit
-          `(pull_request)` contexts (verified empirically on
-          molecule-core/main).
-        - `push` emits `(push)`.
-
-A BP context with no emitter blocks merges forever — Gitea treats
-absent-as-`pending`, NOT absent-as-`skipped`-as-`success`. This is
-the phantom-required-check class
-(`feedback_phantom_required_check_after_gitea_migration`).
-
-The inverse direction (emitter without BP context) is INFORMATIONAL
-only — Tier 2g handles that direction at PR-time. Flagging it here
-on a daily schedule would falsely surface every transitional state
-during a BP rollout.
-
-How the gate works
-------------------
-Daily scheduled run + workflow_dispatch:
-
-  1. GET `branch_protections/{BRANCH}` (needs DRIFT_BOT_TOKEN with
-     repo-admin scope; same persona as ci-required-drift.yml).
-     Graceful-degrade on 403/404 per Tier 2a contract.
-
-  2. Walk `.gitea/workflows/*.yml` via PyYAML AST. For each workflow,
-     enumerate its emitted contexts: `{workflow.name} / {job.name or
-     job-key} ({event})` for each event in `on:` that emits a status.
-
-  3. For each BP context, look for an emitter match. Aggregate
-     orphans.
-
-  4. If orphans exist:
-     - File or PATCH a `[ci-bp-drift]` issue (idempotency contract:
-       search for exact title prefix, edit existing if open).
-     - Apply labels `tier:high` + `ci-bp-drift` (lookup IDs per
-       repo; per `feedback_tier_label_ids_are_per_repo`).
-     - Exit 1.
-
-  5. If no orphans:
-     - Close any existing `[ci-bp-drift]` issue with a clean-state
-       comment.
-     - Exit 0.
-
-Exit codes
-----------
-  0 — clean OR API 403/404 (graceful-degrade, surfaces ::error::).
-  1 — at least one BP context has no emitter.
-  2 — env contract violation, workflows-dir missing, or YAML parse
-      error.

-"""lint_continue_on_error_tracking — Tier 2e per internal#350.
-
-Rule
-----
-Every `continue-on-error: true` directive in `.gitea/workflows/*.yml`
-must be accompanied by a tracker reference comment within 2 lines
-(above OR below the directive's line). The reference is one of:
-
-  * `# mc#NNNN`          — molecule-core issue
-  * `# internal#NNNN`    — molecule-ai/internal issue
-
-The referenced issue must satisfy ALL of:
-
-  1. Exists (HTTP 200 on `/repos/{owner}/{name}/issues/{num}`)
-  2. `state == "open"`
-  3. `created_at` is ≤ MAX_AGE_DAYS days ago (default 14)
-
-A passing reference establishes an audit trail and a forced renewal
-cadence — after 14 days the issue must either be CLOSED (the masked
-defect was fixed) or the comment must point at a NEW tracker
-(deliberate decision to keep masking, requires a paper-trail).
-
-The class this prevents
------------------------
-Phase-3-masked failures. `continue-on-error: true` on `platform-build`
-had been hiding mc#664-class regressions for ~3 weeks before #656
-surfaced them on 2026-05-12. A 14-day cap forces a tracker review
-cycle and surfaces mask-drift within at most 14 days of the original
-defect.
-
-Behaviour-based gate
---------------------
-We parse via PyYAML AST (per `feedback_behavior_based_ast_gates`) to
-detect `continue-on-error: <truthy>` at job-key level, then map each
-location back to its source line via PyYAML's line-tracking loader.
-Comments are scanned from the raw text within a 2-line window of
-that source line. Reformatting (block-scalar vs flow-style) does not
-break the rule because the source-line anchor is the directive's
-own line.
-
-Exit codes
-----------
-  0 — every `continue-on-error: true` has a passing tracker, OR
-      the issue-API endpoint returned 403/404 (token-scope; graceful
-      degrade per Tier 2a contract — surface via ::error:: on stderr
-      but don't red-X every PR over auth).
-  1 — at least one violation (missing/closed/too-old/non-existent
-      tracker).
-  2 — env contract violation, YAML parse error, or workflows-dir
-      missing.
-
-Env
----
-  GITEA_TOKEN     — read scope on the configured repos.
-                    Auto-injected `GITHUB_TOKEN` works for same-repo
-                    issue reads; for `internal#NNN` we need a token
-                    with `molecule-ai/internal` read scope. Use
-                    DRIFT_BOT_TOKEN (same persona as other Tier 2
-                    lints).
-  GITEA_HOST      — e.g. git.moleculesai.app
-  REPO            — `owner/name` for `mc#NNNN` lookups
-  INTERNAL_REPO   — `owner/name` for `internal#NNNN` lookups
-                    (defaults to derived `molecule-ai/internal`)
-  WORKFLOWS_DIR   — defaults to `.gitea/workflows`
-  MAX_AGE_DAYS    — defaults to 14

-"""lint_mask_pr_atomicity — Tier 2d structural enforcement per internal#350.
-
-Rule
-----
-A PR whose diff touches `.gitea/workflows/ci.yml` AND modifies EITHER:
-
-  - any `continue-on-error:` value, OR
-  - the `all-required` sentinel job's `needs:` block
-
-must EITHER:
-
-  - Touch BOTH atomically in the same PR (preferred), OR
-  - Cross-link the paired PR via a literal `Paired: #NNN` reference in
-    the PR body OR in any commit message between BASE_SHA and HEAD_SHA.
-
-The class this prevents
------------------------
-PR#665 (interim `continue-on-error: true` on `platform-build`) and
-PR#668 (sentinel-`needs` demotion of the same job) were designed as a
-pair but merged solo — #665 landed at 04:47Z 2026-05-12, #668 was still
-open at 05:07Z when the main-red watchdog (#674) fired. Result: ~20
-minutes of `main` red and a cascade of false-positives on unrelated PRs.
-
-The lint operates on the YAML AST (PyYAML), not grep, per
-`feedback_behavior_based_ast_gates`: a refactor that moves `continue-on-error`
-between job keys, or renames the `all-required` job, would still be
-detected because we walk the parsed structure.
-
-Why this works on Gitea 1.22.6
-------------------------------
-We don't use any 1.22.6-missing endpoints (no `/actions/runs/*`, no
-`branch_protections/*` — Tier 2f/g need those; Tier 2d does not). All
-required inputs come from the workflow `pull_request` event payload
-(BASE_SHA, HEAD_SHA, PR_BODY) and from local git via `git show`/`git log`.
-The auto-injected `GITHUB_TOKEN` is enough; we don't need
-DRIFT_BOT_TOKEN.
-
-Exit codes
-----------
-  0 — ci.yml not in diff, OR diff is no-op for the rule predicates,
-      OR atomicity satisfied (both touched), OR a valid `Paired: #NNN`
-      reference is present.
-  1 — exactly ONE of {coe, sentinel-needs} touched AND no valid
-      `Paired: #NNN` reference. The split-pair regression class.
-  2 — env contract violation (BASE_SHA / HEAD_SHA missing) or YAML
-      parse error on either side.
-
-Env
----
-  BASE_SHA          — PR base (pull_request.base.sha)
-  HEAD_SHA          — PR head (pull_request.head.sha)
-  PR_BODY           — pull_request.body (may be empty)
-  CI_WORKFLOW_PATH  — defaults to `.gitea/workflows/ci.yml`
-  SENTINEL_JOB_KEY  — defaults to `all-required`

-#!/usr/bin/env python3
-"""lint-pre-flip-continue-on-error — block a PR that flips a job from
-``continue-on-error: true`` to ``continue-on-error: false`` (or removes
-the key while the base had it ``true``) without proof that the job's
-recent runs on the target branch are actually green.
-
-Empirical class — PR #656 / mc#664:
-  PR #656 (RFC internal#219 Phase 4) flipped 5 ``platform-build``-class
-  jobs ``continue-on-error: true → false`` on the basis of a
-  "verified green on main via combined-status check". But that "green"
-  was the LIE produced by the prior ``continue-on-error: true``:
-  Gitea Quirk #10 (internal#342 + dup #287) — when a step inside a
-  job marked ``continue-on-error: true`` fails, the job-level status
-  is still rolled up as ``success``. So the precondition the PR
-  claimed to verify was structurally fooled by the bug being
-  flipped.
-
-  mc#664 then captured the surfaced defects (2 unrelated, mutually-
-  masked regressions):
-
-    Class 1: sqlmock helper drift since 2f36bb9a (24 days old)
-    Class 2: OFFSEC-001 contract collision since 7d1a189f (1 day old)
-
-  Codified 04:35Z as hongming-pc2 charter §SOP-N rule (e)
-  "run-log-grep-before-flip": pull the actual run log + grep for
-  ``--- FAIL`` / ``FAIL\\s`` BEFORE flipping; don't trust the masked
-  combined-status.
-
-This script structurally enforces that rule at PR time.
-
-How it works (one PR tick):
-  1. Parse the diff: compare ``.gitea/workflows/*.yml`` at PR base
-     vs PR head. For each file present in both, parse the YAML AST
-     and walk ``jobs.<key>.continue-on-error`` on each side. A
-     "flip" is base ∈ {true} AND head ∈ {false, None/absent}. We
-     coerce truthy/falsy per YAML semantics (PyYAML normalizes
-     ``true``/``True``/``yes`` to ``True``).
-  2. For each flipped job, derive its commit-status context name as
-     ``"{workflow.name} / {job.name or job.key} (push)"`` — that's
-     how Gitea Actions emits the context for runs on
-     ``main``/``staging`` (push event, see also expected_context()
-     in ci-required-drift.py).
-  3. Pull the last N commits of the target branch (PR base), fetch
-     combined commit-status per commit, scan ``statuses[]`` for
-     contexts matching ANY of the flipped jobs. For each match,
-     fetch the actual run log via the web-UI route
-     ``{server_url}/{repo}/actions/runs/{run_id}/jobs/{job_idx}/logs``
-     (per memory ``reference_gitea_actions_log_fetch`` — Gitea 1.22.6
-     lacks REST ``/actions/runs/*`` endpoints; the web-UI route is the
-     only working path; see ``reference_gitea_1_22_6_lacks_rest_rerun_endpoints``).
-  4. Grep each log for the Go-test failure markers ``--- FAIL`` /
-     ``FAIL\\s+<package>`` AND the bash-step error sentinel
-     ``::error::``. If ANY recent log shows any of these AND the
-     status itself reads ``success``, the job was masked. ``::error::``
-     the flip with the offending test name + offending run URL +
-     the regression commit (HEAD of the run).
-  5. Exit 1 if any flips have at least one masked run; exit 0
-     otherwise.
-
-Halt-on-noise contract:
-  - If a recent log fetch 404s (already-pruned-via-act_runner-gc,
-     transient gitea-web outage): emit ``::warning::`` and treat the
-     run as "log unavailable" — does NOT block the flip; logged so
-     a curious reviewer can re-run.
-  - If a flipped job has ZERO recent runs on the target branch (newly
-     added workflow): emit ``::warning::`` "no run history to verify"
-     and allow the flip. This is the only way a NEW workflow can ever
-     ship with ``continue-on-error: false``; otherwise we'd have a
-     chicken-and-egg.
-
-Behavior-based AST gate per ``feedback_behavior_based_ast_gates``:
-  - YAML parsed via PyYAML safe_load on BOTH sides of the diff
-  - No grep-by-line — formatting changes (comment churn, key order)
-    don't false-positive a flip
-  - Job-key match — so a rename ``platform-build → core-be-build``
-    appears as a DELETE + an ADD, not a flip (the delete side has no
-    new value to compare against; the add side has no base side).
-
-Run locally (works against this repo, requires PyYAML + Gitea token
-that can read combined-commit-status):
-
-    GITEA_TOKEN=... GITEA_HOST=git.moleculesai.app \\
-      REPO=molecule-ai/molecule-core BASE_REF=main \\

-
-Rule
-----
-When a PR adds a NEW commit-status emission (a context that didn't
-exist on the base side), the workflow file must carry one of three
-directive comments adjacent to the new job:
-
-  (a) `# bp-required: yes`
-      The new context MUST already be in
-      `branch_protections/<branch>.status_check_contexts`. Verified
-      via Gitea API at PR time.
-
-  (b) `# bp-required: pending #NNN`
-      Acknowledged asymmetry; references an OPEN tracking issue that
-      will follow up with the BP PATCH.
-
-  (c) `# bp-exempt: <free-text reason>`
-      Informational job, not intended to be a required gate.
-
-No directive on a new emitter → FAIL with a 3-option fix-hint.
-
-The class this prevents
------------------------
-PR#656 added `CI / all-required (pull_request)` as a sentinel context
-that workflows emit, but BP did NOT list it. When `platform-build`
-failed, `all-required` failed, but BP let the PR merge anyway →
-cascade to mc#664. With this lint, PR#656 would have been blocked
-until either the BP PATCH ran alongside OR the author added a
-`bp-required: pending` directive.
-
-Why directives MUST live in the workflow YAML
----------------------------------------------
-The directive comment lives with the emitter so a scheduled
-audit (Tier 2f, daily) can read the same source. PR-body-only
-directives invisibly evaporate on merge — the asymmetry would
-return to undetected. PR-body claims are advisory; workflow-file
-comments are the contract.
-
-How "new emission" is detected
-------------------------------
-Diff base..head over `.gitea/workflows/*.yml`. For each YAML file
-that's added or modified:
-  - Parse both base-side and head-side via PyYAML AST.
-  - Enumerate emitted contexts on each side using the same rules as
-    Tier 2f (workflow.name + job.name|key + event-mapping).
-  - `new_contexts = head_contexts - base_contexts`.
-
-If `new_contexts` is empty after de-dup, no rule applies → pass.
-
-Per `feedback_behavior_based_ast_gates`: comment scanning uses raw
-text in a small window around the job-key line, NOT regex over the
-full file. This avoids matching `bp-required:` mentioned in a
-comment unrelated to the new job.

-Exit codes
-----------
-  0 — no new emissions, all new emissions have valid directives,
-      or BP read errored (graceful-degrade per Tier 2a contract).
-  1 — at least one new emission lacks a directive, or has
-      `bp-required: yes` but the context is missing from BP.
-  2 — env contract violation or YAML parse error.

-#        a. Is the section marker present in PR body? (author answered)
-#        b. Is there ≥1 unrevoked /sop-ack from a non-author whose
-#           team-membership matches required_teams?
-#   5. POST /repos/{R}/statuses/{sha}    — context
-#      `sop-checklist / all-items-acked (pull_request)`,
-#      state=success | failure | pending, description=`acked: N/M …`.
-#
-# Trust boundary (mirrors RFC#324 §A4):
-#   This script is loaded from the BASE branch. The workflow's
-#   actions/checkout step pins ref=base.sha. PR-HEAD code is never
-#   executed. We only HTTP-call the Gitea API.
-#
-# Token scope:
-#   - read:repository / read:organization to enumerate PR + comments
-#     + team membership (Gitea 1.22.6 quirk: team-membership endpoint
-#     returns 403 if token owner is not in the team; see review-check.sh
-#     for the same gotcha — we surface the same fail-closed message).
-#   - write:repository for `POST /repos/{R}/statuses/{sha}`. Unlike
-#     RFC#324's pattern (which uses the JOB's own pass/fail as the
-#     status), we POST the status explicitly because the gate posts
-#     a single multi-item status with a richer description than a
-#     bare success/failure context can carry.
-#
-# Slug normalization rules (canonical form: kebab-case):
-#   - Lowercase
-#   - Whitespace + underscores → single dash
-#   - Strip non [a-z0-9-] characters
-#   - Collapse adjacent dashes
-#   - Strip leading/trailing dashes
-#   - If the result is a digit string (e.g. "1"), look up via
-#     config.items[*].numeric_alias to get the kebab-case slug.
-#
-#   Examples:
-#       "Comprehensive_Testing"  → "comprehensive-testing"
-#       "comprehensive testing"  → "comprehensive-testing"
-#       "1"                      → "comprehensive-testing"
-#       "Five-Axis-Review"       → "five-axis-review"
-#
-# Revoke semantics:
-#   /sop-revoke <slug> [reason] — most-recent comment per (slug, user)
-#   wins. So if Alice posts /sop-ack X then later /sop-revoke X, her ack
-#   for X is invalidated. Bob's prior /sop-ack X is unaffected. If Alice
-#   posts /sop-revoke X then later /sop-ack X again, the ack is restored.

-# RFC#351 Step 2 of 6 — implementation MVP. Tests cover:
-#   - slug normalization (the 4 example variants in the script header)
-#   - parse_directives (ack, revoke, with/without note, mid-comment, etc.)
-#   - section_marker_present (empty answer rejected, filled answer ok)
-#   - compute_ack_state (self-ack rejected, team probe applied, revoke
-#     invalidates own prior ack, peer's ack survives unrevoked)
-#   - render_status (state + description format)
-#   - get_tier_mode (label-driven, default fallback)
-#   - load_config (default config parses cleanly with both PyYAML and
-#     the bundled minimal parser)
-#
-# All tests run WITHOUT touching the Gitea API — the team-probe
-# callable is dependency-injected.

-# SOP-Checklist gate — per-item required reviewer teams.
-#
-# RFC#351 v1 starter set. Each item lists:
-#   slug              — canonical kebab-case form used in /sop-ack <slug>
-#   pr_section_marker — substring matched in the PR body to detect that
-#                       the author filled in this item (case-insensitive)
-#   required_teams    — list of Gitea team names; an ack from ANY one of
-#                       these teams (logical OR) satisfies the item.
-#                       Membership is probed at gate-time via
-#                       GET /api/v1/teams/{id}/members/{login}.
-#                       Team-id resolution happens at script start via
-#                       GET /api/v1/orgs/{org}/teams (cheap, one call).
-#   numeric_alias     — 1..7; lets reviewers type `/sop-ack 3` as a
-#                       shortcut for `/sop-ack staging-smoke`.
-#
-# WHY THESE TEAM MAPPINGS:
-#   The RFC table referenced persona-role names like `core-qa`,
-#   `core-be`, `core-devops` — these are individual Gitea user logins,
-#   not teams. The Gitea team-membership API is /teams/{id}/members/{u},
-#   so we need actual teams. Orchestrator preflight 2026-05-12 verified
-#   only these teams exist on molecule-ai: ceo(5), engineers(2),
-#   managers(6), qa(20), security(21), Owners(1), and bot teams. We
-#   map the RFC roles to the closest existing team and surface the
-#   mapping explicitly so it's reviewable.
-#
-# HOW TO EDIT:
-#   - Tightening: replace `engineers` with a smaller team after creating
-#     it (e.g. a new `senior-engineers` team if needed).
-#   - Loosening: add another team to required_teams (OR semantics).
-#   - Add an item: append to items list and document the slug below.
-#
-# AUTHOR SELF-ACK IS FORBIDDEN regardless of which team contains them
-# — the gate script enforces commenter != PR author before checking
-# team membership.

-# Tier-aware failure mode (RFC#351 open question 2):
-#   For tier:high — hard-fail (status `failure`, blocks merge via BP).
-#   For tier:medium — hard-fail (same as high; medium is non-trivial).
-#   For tier:low — soft-fail (status `pending` with `acked: N/M` in the
-#                  description). BP can choose to require the context
-#                  or not for low-tier PRs.
-# If no tier label is present, default to medium (hard-fail) — every PR
-# should have a tier label per sop-tier-check, and absence indicates
-# a missing-tier defect we should surface, not silently lower the bar.

-# Tier 2f scheduled lint (per mc#774) — detects drift between
-# `branch_protections/<branch>.status_check_contexts` and the set of
-# contexts emitted by `.gitea/workflows/*.yml`.
-#
-# Rule
-# ----
-# For each protected branch context (Source A — BP), there must exist
-# at least one emitting workflow + job pair (Source B — workflow YAML
-# + on:-event mapping) whose runtime status-name maps to it. The
-# inverse direction (emitter without BP context) is informational
-# only — Tier 2g handles that at PR-time.
-#
-# Why this exists
-# ---------------
-# A BP-required context with no emitter blocks merges forever — Gitea
-# 1.22.6 treats absent-as-`pending`, NOT absent-as-`skipped`. The
-# phantom-required-check class previously surfaced as
-# `feedback_phantom_required_check_after_gitea_migration` (a port
-# kept the GitHub context name after rename to Gitea, but no
-# workflow emitted under the new name).
-#
-# This lint catches the same class structurally + a forward case:
-# workflow renamed/deleted while still in BP.
-#
-# Scope
-# -----
-# Scheduled daily. We DON'T run on `pull_request` because (a) the
-# emitter side moves with PR diffs (transitional state false-flags)
-# and (b) Tier 2g handles emitter-side drift at PR-time.
-#
-# Cross-repo
-# ----------
-# Today this runs only on molecule-core/main. Per internal#349
-# (cross-repo BP sweep) Class-D repos will get the same lint after
-# their BP rollouts.
-#
-# Auth
-# ----
-# `GET /repos/.../branch_protections/{branch}` requires repo-admin
-# role on Gitea 1.22.6. We use DRIFT_BOT_TOKEN (same persona as
-# ci-required-drift.yml — `internal#329` provisioning trail).
-# Graceful-degrade per Tier 2a contract: 403/404 → exit 0 with
-# ::error::.
-#
-# Idempotency
-# -----------
-# The drift issue is filed with title prefix
-# `[ci-bp-drift] {repo}/{branch}: BP→emitter mismatch`. The script
-# searches OPEN issues for an exact title-prefix match and PATCHes
-# the existing issue (if any) instead of POSTing a duplicate.
-# Mirrors `ci-required-drift.py`'s contract.
-#
-# Phase contract (RFC internal#219 §1 ladder)
-# -------------------------------------------
-# Lands at `continue-on-error: true` (Phase 3). After 7 days of clean
-# scheduled runs on `main`, flip to `false` so a scheduled failure

-# Tier 2e hard-gate lint (per mc#774) — every
-# `continue-on-error: true` in `.gitea/workflows/*.yml` must carry a
-# `# mc#NNNN` or `# internal#NNNN` tracker comment within 2 lines,
-# the referenced issue must be OPEN, and ≤14 days old.
-#
-# Why this exists
-# ---------------
-# `continue-on-error: true` on `platform-build` had been hiding
-# mc#774-class regressions for ~3 weeks before #656 surfaced them on
-# 2026-05-12. A 14-day cap on tracker age forces a review cycle and
-# surfaces mask-drift within at most 14 days of the original defect.
-# Each `continue-on-error: true` gets a paper trail — close or renew.
-#
-# How the gate works
-# ------------------
-# 1. Walk `.gitea/workflows/*.yml` via PyYAML's line-tracking loader
-#    (per `feedback_behavior_based_ast_gates`) and find every job
-#    whose `continue-on-error` evaluates truthy (`true` or string
-#    `"true"` — Gitea's evaluator coerces strings).
-# 2. For each, scan ±2 lines of the directive's source line for a
-#    `# mc#NNNN` or `# internal#NNNN` comment. Inline-trailing
-#    comments on the directive line count.
-# 3. For each tracker reference, GET the issue from the Gitea API.
-#    Validate: exists, `state == open`, `created_at` ≤ MAX_AGE_DAYS.
-# 4. Aggregate ALL violations (not short-circuit) and exit 1 if any.
-#
-# Triggers
-# --------
-# Runs on PR events (paths-filter on `.gitea/workflows/**`) AND on
-# a daily schedule. PR runs catch the violation at introduction time.
-# Schedule runs catch the AGE-EXPIRY class: a tracker that was ≤14d
-# old when the PR landed but is now 20d old, with the underlying
-# defect still unfixed. Per `feedback_chained_defects_in_never_tested_workflows`,
-# scheduled drift detection is the second half of the gate.
-#
-# Phase contract (RFC internal#219 §1 ladder)
-# -------------------------------------------
-# Lands at `continue-on-error: true` (Phase 3 — surface broken shapes
-# without blocking). The pre-existing `continue-on-error: true`
-# directives on `main` will all violate this lint at first
-# (intentional — they're the masked defects this lint exists to
-# surface). Each must be triaged: file a fresh tracker comment,
-# close-and-flip, or document the deliberate keep-mask in a fresh
-# 14-day-renewable tracker. After main is clean for 3 days,
-# follow-up PR flips this workflow's continue-on-error to false.
-# Tracking: mc#774.

-# Tier 2d hard-gate lint (per mc#774) — blocks PRs that touch
-# `.gitea/workflows/ci.yml` and modify ONLY ONE of {continue-on-error,
-# all-required.sentinel.needs} without a `Paired: #NNN` reference in
-# the PR body or in a commit message.
-#
-# Why this exists
-# ---------------
-# PR#665 (interim `continue-on-error: true` on `platform-build`) and
-# PR#668 (sentinel-`needs` demotion of the same job) were designed as a
-# pair but merged solo — #665 landed at 04:47Z 2026-05-12, #668 was
-# still open at 05:07Z when the main-red watchdog (#674) fired. Result:
-# ~20 minutes of `main` red and a cascade of false-positives on
-# unrelated PRs. This lint structurally prevents that class.
-#
-# How the gate works
-# ------------------
-# 1. The workflow runs on every PR whose diff touches ci.yml (paths
-#    filter). It is NOT a required check on `main` because the rule is
-#    diff-based — running it on PRs that don't touch ci.yml would
-#    produce a `pending` status forever (per
-#    `feedback_path_filtered_workflow_cant_be_required`).
-# 2. The script reads `BASE_SHA:ci.yml` and `HEAD_SHA:ci.yml`, parses
-#    both via PyYAML AST (per `feedback_behavior_based_ast_gates` — no
-#    grep, no regex on the raw text — so a YAML-shape refactor still
-#    detects).
-# 3. Walks `jobs.*.continue-on-error` on each side; flags any value
-#    diff. Reads `jobs.all-required.needs` on each side; flags any
-#    set diff (order-insensitive — `needs:` is engine-unordered).
-# 4. If both predicates fired → atomic, OK. If neither → no risk, OK.
-#    If exactly one fired → require `Paired: #NNN` in PR body OR in
-#    any commit message between base..head; else fail.
-#
-# Phase contract (RFC internal#219 §1 ladder)
-# -------------------------------------------
-# This workflow lands at `continue-on-error: true` (Phase 3 — surface
-# regressions without blocking PRs while the rule beds in).
-# Follow-up PR flips to `false` once we have ≥3 days of clean runs on
-# `main` and no false-positives. Tracking issue: mc#774.

-# Pre-merge gate: blocks PRs that flip `continue-on-error: true → false`
-# on any job in `.gitea/workflows/*.yml` WITHOUT proof that the affected
-# job's recent runs on the target branch (PR base) are actually green.
-#
-# Empirical class: PR #656 / mc#774. PR #656 (RFC internal#219 Phase 4)
-# flipped 5 platform-build-class jobs `continue-on-error: true → false`
-# on the basis of a "verified green on main via combined-status check".
-# But that "green" was the LIE the prior `continue-on-error: true`
-# produced: Gitea Quirk #10 (internal#342 + dup #287) — a failed step
-# inside a `continue-on-error: true` job rolls up to a `success`
-# job-level status. The precondition the PR claimed to verify was
-# structurally fooled by the bug being flipped.
-#
-# mc#774 captured the surfaced defects (2 mutually-masked regressions):
-#   - Class 1: sqlmock helper drift since 2f36bb9a (24 days old)
-#   - Class 2: OFFSEC-001 contract collision since 7d1a189f (1 day old)
-#
-# Codified 04:35Z as hongming-pc2 charter §SOP-N rule (e)
-# "run-log-grep-before-flip" — now structurally enforced here at PR
-# time, ahead of merge.
-#
-# How the gate works:
-#   1. Read every `.gitea/workflows/*.yml` at the PR base SHA AND at
-#      the PR head SHA via `git show <sha>:<path>` (no checkout
-#      needed).
-#   2. Parse both sides via PyYAML AST (NOT grep — per
-#      `feedback_behavior_based_ast_gates`). Walk `jobs.<key>.
-#      continue-on-error` on each side. A flip is base=true,
-#      head=false.
-#   3. For each flipped job, render the commit-status context as
-#      `"{workflow.name} / {job.name or job.key} (push)"` — that's
-#      how Gitea Actions emits the per-context status on `main`/
-#      `staging` runs.
-#   4. Pull last 5 commits on the PR base branch, fetch combined
-#      commit-status per commit, scan for the target context. For
-#      each match, fetch the run log via the web-UI route
-#      `{server_url}/{repo}/actions/runs/{run_id}/jobs/{job_idx}/logs`
-#      (per `reference_gitea_actions_log_fetch` —
-#      Gitea 1.22.6 lacks REST `/actions/runs/*`; web-UI is the
-#      only working path, see also
-#      `reference_gitea_1_22_6_lacks_rest_rerun_endpoints`).
-#   5. Grep each log for `--- FAIL`, `FAIL\s`, `::error::`. If
-#      the status is `success` but the log shows any of these,
-#      the job was masked. Block the PR with `::error::`.
-#
-# Graceful-degrade contract (per task halt-conditions):
-#   - Log fetch 404 (act_runner pruned the log, transient outage):
-#     emit `::warning::` "log unavailable" — does NOT block.
-#   - Zero recent runs of the flipped job's context on the base
-#     branch (newly added workflow): emit `::warning::` "no run
-#     history to verify" — allow the flip. Chicken-and-egg
-#     exemption.
-#   - YAML parse error in one of the workflow files: warn-only,
-#     don't block — the YAML lint workflows catch this separately.

-# Tier 2g hard-gate lint (per mc#774) — diff-based PR-time
-# check. When a PR adds a NEW commit-status emission (workflow YAML
-# `name:` + job `name:`-or-key + on:-event), the workflow file must
-# carry one of three directives adjacent to the new job:
-#
-#   - `# bp-required: yes`           — and BP must list the context
-#   - `# bp-required: pending #NNN`  — acknowledged asymmetry + tracker
-#   - `# bp-exempt: <reason>`        — informational job, not a gate
-#
-# Default (no directive on a new emitter) = FAIL.
-#
-# Why this exists
-# ---------------
-# PR#656 added `CI / all-required (pull_request)` as a sentinel
-# context that workflows emit, but BP did NOT list it. When
-# platform-build failed, all-required failed, but BP let the PR
-# merge anyway → cascade to mc#774. With this lint, PR#656 would
-# have been blocked until either the BP PATCH ran alongside OR
-# the author added a `bp-required: pending` directive.
-#
-# Tier 2g vs Tier 2f
-# ------------------
-# Tier 2g runs at PR-time (diff-based) and BLOCKS the merge.
-# Tier 2f runs daily (scheduled) and FILES a drift issue. They
-# share the workflow-context enumeration helpers
-# (`_event_map`, `workflow_contexts`, `_job_display`) but the
-# semantics are intentionally distinct so they're separate scripts.
-# Co-design is documented in mc#774.
-#
-# Directive comment lives in the workflow file (NOT PR body)
-# ----------------------------------------------------------
-# A PR-body claim of "BP exempt" evaporates on merge — the
-# asymmetry returns to undetected state and Tier 2f's daily
-# scheduled audit can't see it. The directive must live with the
-# emitter so both PR-time (Tier 2g) and post-merge (Tier 2f)
-# readers consume the same source.
-#
-# Phase contract (RFC internal#219 §1 ladder)

-# Lands at `continue-on-error: true` (Phase 3 — surface the

-# lint-required-no-paths — structural enforcement of
-# `feedback_path_filtered_workflow_cant_be_required`.
-#
-# Fails the PR if ANY workflow whose status-check context appears in
-# `branch_protections/main.status_check_contexts` carries a
-# `paths:` or `paths-ignore:` filter in its `on:` block.
-#
-# Why this exists:
-#   A required-check workflow with a paths filter silently degrades the
-#   merge gate. If a PR's diff doesn't touch the filter, the workflow
-#   never fires; Gitea (1.22.6) reports the required context as
-#   `pending` (NOT `skipped == success`), so the PR cannot merge. For a
-#   docs-only PR against `paths: ['**.go']`, the PR is wedged forever.
-#
-#   Previously prevented only by reviewer vigilance + the saved memory
-#   `feedback_path_filtered_workflow_cant_be_required`. This workflow
-#   makes it a hard CI gate.
-#
-# Forward-compat scope:
-#   Today (2026-05-11) molecule-core/main protects 3 contexts:
-#     - "Secret scan / Scan diff for credential-shaped strings (pull_request)"
-#     - "sop-tier-check / tier-check (pull_request)"
-#     - "CI / all-required (pull_request)"
-#   Per RFC#324 Step 2 the required-list expands to ~5 contexts
-#   (qa-review, security-review added). Each new required context's
-#   workflow must remain unconditional. This lint pins that contract.
-#
-# Meta-required-check:
-#   This workflow ITSELF deliberately has NO `paths:` filter on its `on:`
-#   block — otherwise a paths-non-matching PR could bypass the check.
-#   Self-evident from this file: only `pull_request` types + no paths.
-#
-# Auth:
-#   `GET /repos/.../branch_protections/{branch}` requires repo-admin
-#   role in Gitea 1.22.6. The workflow-default `GITHUB_TOKEN` is
-#   non-admin (read-only), so we re-use `DRIFT_BOT_TOKEN` (same persona
-#   that powers `ci-required-drift.yml` — verified working there).
-#   If `DRIFT_BOT_TOKEN` becomes unavailable, the script exits 0 with a
-#   loud `::error::` rather than red-X every PR — token-scope issues
-#   should be fixed at the token, not surfaced as a gate failure on
-#   every unrelated PR.
-#
-# Behavior-based gate per `feedback_behavior_based_ast_gates`:
-#   YAML AST walk (PyYAML), NOT grep. Workflow renames, formatting
-#   changes (block-scalar vs flow-style), or moving `paths:` between
-#   `pull_request:` and `pull_request_target:` all still detect.
-#
-# IMPORTANT — Gitea 1.22.6 parser quirk per
-# `feedback_gitea_workflow_dispatch_inputs_unsupported`: do NOT add an
-# `inputs:` block to `workflow_dispatch:` — Gitea 1.22.6 rejects the
-# entire workflow as "unknown on type" and it registers for ZERO events.

-# sop-checklist-gate — peer-ack merge gate for SOP-checklist items.
-#
-# RFC#351 Step 2 of 6 (implementation MVP).
-#
-# === DESIGN ===
-#
-# Goal: each PR must answer 7 SOP-checklist questions in its body,
-# and each item must have at least one /sop-ack <slug> comment from
-# a non-author peer in the required team. BP requires the
-# `sop-checklist / all-items-acked (pull_request)` status to merge.
-#
-# Triggers:
-#   - `pull_request_target`: opened, edited, synchronize, reopened
-#       → fires when PR opens, body is edited (refire — RFC#351 §4),
-#         or new code is pushed (head.sha changes → stale status would
-#         be auto-discarded by BP via dismiss_stale_reviews, but the
-#         status itself is per-SHA so we re-post on the new head).
-#   - `issue_comment`: created, edited, deleted
-#       → fires on any new comment so /sop-ack / /sop-revoke take
-#         effect immediately (Gitea 1.22.6 doesn't refire on
-#         pull_request_review per feedback_pull_request_review_no_refire,
-#         so issue_comment is the canonical refire channel).
-#
-# Trust boundary (mirrors RFC#324 §A4 + sop-tier-check security note):
-#   `pull_request_target` (not `pull_request`) — workflow def is loaded
-#   from BASE branch, so a PR cannot rewrite this workflow to exfiltrate
-#   the token. The `actions/checkout` step pins `ref: base.sha` so the
-#   script ALSO comes from BASE. PR-HEAD code is never executed in the
-#   runner.
-#
-# Token scope:
-#   - read:repository, read:organization for PR + comments + team probes
-#   - write:repository for POST /statuses/{sha}
-#   - The token owner MUST be a member of every team referenced by the
-#     config's required_teams (else /teams/{id}/members/{login} returns
-#     403 — see review-check.sh same-gotcha doc). For the MVP we use
-#     the dev-lead token (a member of engineers, managers, qa, security)
-#     via a repo secret `SOP_CHECKLIST_GATE_TOKEN`. Provisioning of that
-#     secret is a follow-up authorization step (separate from this PR).
-#
-# Failure mode: tier-aware (RFC#351 open question 2):
-#   - tier:high   → state=failure (hard-fail; BP blocks merge)
-#   - tier:medium → state=failure (hard-fail; same)
-#   - tier:low    → state=pending (soft-fail; BP can choose to require
-#                    this context or skip for low-tier PRs)
-#   - missing/no-tier → state=failure (default-mode: hard — never lower
-#                    the bar per feedback_fix_root_not_symptom)
-#
-# Slash-command contract (RFC#351 v1 + §A1.1-style notes from RFC#324):
-#
-#   /sop-ack <slug-or-numeric-alias> [optional note]
-#       — register a peer-ack for one checklist item.
-#       — slug accepts kebab-case, snake_case, or natural-spaces
-#         (all normalize to canonical kebab-case).
-#       — numeric 1..7 maps via config.items[*].numeric_alias.
-#       — most-recent (user, slug) directive wins.
-#
-#   /sop-revoke <slug-or-numeric-alias> [reason]
-#       — invalidate the commenter's own prior /sop-ack for this slug.
-#       — does NOT affect other peers' acks on the same slug.
-#       — most-recent (user, slug) directive wins, so a later /sop-ack
-#         re-restores the ack.
-#
-# The eval is read-only + idempotent (read PR + comments + team
-# membership, compute, post status). Re-running on any event is safe —
-# the new status overwrites the previous one for the same context.

-#
-# Codified ECR :<source-tag> → :<dest-tag> promote + tenant fleet redeploy.
-# Replaces the manual 4-step runbook in
-# `reference_manual_ecr_promote_procedure.md` (memory) and closes
-# molecule-ai/molecule-core#660.
-#
-# Default flow (no flags):
-#   1. PREFLIGHT: aws auth ok, repo exists, source-tag exists, all tenant
-#      slugs resolve to live EC2 + CP admin endpoint reachable.
-#   2. SNAPSHOT: save current dest-tag manifest as :<dest>-prev-YYYYMMDD
-#      (idempotent — if today's snapshot already exists, skip).
-#   3. PROMOTE: copy <source-tag> manifest → <dest-tag>. Records the new
-#      digest so step 5 can verify.
-#   4. REDEPLOY: per-tenant POST /cp/admin/tenants/<slug>/redeploy. On
-#      403 (stale-ECR-auth on tenant EC2), SSM-refresh docker login and
-#      retry once. Hard-fail if both attempts fail.
-#   5. VERIFY: per-tenant curl /buildinfo + /health. /buildinfo.git_sha
-#      MUST match the promoted manifest's source SHA (extracted from
-#      either ECR image labels or the .git_sha tag annotation).
-#
-# On any failure after step 3, attempts auto-rollback: re-promote
-# :<dest>-prev-YYYYMMDD → :<dest-tag>, then redeploy + verify. Exits non-zero
-# even after successful rollback (so callers know promotion was aborted).
-#
-# Usage:
-#   scripts/promote-tenant-image.sh \
-#     --source-tag staging-latest \
-#     --dest-tag latest \
-#     --tenants chloe-dong,hongming \

-#     [--dry-run] \
-#     [--skip-rollback] \
-#     [--mock-dir <dir>]
-#
-# Test harness (referenced by scripts/test-promote-tenant-image.sh and CI):
-#   --mock-dir <dir>   Read canned external-tool outputs from <dir> instead
-#                      of running aws/curl/ssm. Each function reads from a
-#                      filename matching the function name. Stdout of the
-#                      mock files is returned verbatim; a `.rc` sidecar file
-#                      controls exit code. Mock dir is the only way to
-#                      exercise the failure branches in unit tests.
-#
-# Exit codes:
-#   0   promote + redeploy + verify all green
-#   1   preflight failed (no mutations performed)

-"""Tests for `.gitea/scripts/lint_bp_context_emit_match.py` — Tier 2f lint.
-
-Structural enforcement of internal#350 Tier 2f: BP `status_check_contexts`
-and the set of contexts emitted by `.gitea/workflows/*.yml` must agree.
-
-Bidirectional rule:
-  (a) BP-only: every context in `branch_protections/<branch>.status_check_contexts`
-      must have at least one EMITTER — a workflow `name:` + job `name:` (or job key)
-      + `pull_request` (or `push`) event that produces it. A BP context without
-      an emitter blocks merges forever (Gitea treats absent-as-pending, NOT
-      absent-as-skipped). This is the phantom-required-check class
-      (`feedback_phantom_required_check_after_gitea_migration`).
-
-  (b) EMITTER-only: NO automatic flag. The PR#656 case (workflow added a
-      sentinel context not yet in BP) is Tier 2g's job — a diff-based PR-time
-      lint. Tier 2f runs scheduled and would falsely flag every transitional
-      state during a BP rollout. We only flag the BP-empty case in this
-      direction as a NOTICE (informational), not as an error.
-
-Tier 2f runs on a daily schedule + workflow_dispatch and files a
-`[ci-bp-drift]`-tagged issue on mismatch.
-
-Test classes (per `feedback_branch_count_before_approving`):
-
-  - test_perfect_match_passes              — BP has [X]; workflows emit X.
-    Exit 0. No issue filed/edited.
-  - test_bp_orphan_context_fails           — BP has [Y] but no workflow
-    emits Y. Exit 1. Issue body lists the orphan and the closest
-    candidate workflow names (Levenshtein-1 suggestion for typos).
-  - test_emitter_orphan_only_warns         — workflow emits Z but BP
-    doesn't have it. Exit 0 with ::notice:: (NOT ::error::) because
-    Tier 2g handles this at PR time.
-  - test_multiple_orphans_aggregated       — two BP orphans surfaced
-    together, not short-circuited.
-  - test_bp_empty_lints_nothing            — BP has no contexts.
-    Exit 0 cleanly.
-  - test_api_403_skips_gracefully          — branch_protections endpoint
-    403s (token-scope). Exit 0 with ::error::, do NOT red-X.
-  - test_api_404_skips_gracefully          — branch has no protection.
-    Exit 0 cleanly.
-  - test_context_event_match_required      — BP context says `(push)` and
-    workflow only emits on `pull_request`. That's NOT a match — the
-    BP-required gate would still wedge. Exit 1.
-  - test_workflow_event_mapping_pull_request_target — `pull_request_target`
-    in workflow `on:` emits a `(pull_request)` context (Gitea convention).
-    Match counts.
-  - test_idempotent_issue_filing           — when an issue already exists
-    with the canonical title prefix, edit it instead of POSTing a new one
-    (idempotency contract — mirrors ci-required-drift).

-"""Tests for `.gitea/scripts/lint_continue_on_error_tracking.py` — Tier 2e lint.
-
-Structural enforcement of internal#350 Tier 2e: every
-`continue-on-error: true` directive in `.gitea/workflows/*.yml` must be
-accompanied by a `# mc#NNNN` or `# internal#NNNN` comment within 2 lines
-(above OR below), the referenced issue must be OPEN, and ≤14 days old
-counted from `created_at`. Older than 14 days → fail, forces close-or-renew.
-
-The class this lint exists to prevent: Phase-3-masked failures.
-`continue-on-error: true` on platform-build had been hiding mc#664-class
-regressions for ~3 weeks before #656 surfaced them. A 14-day cap forces
-a tracker review cycle, preventing indefinite-mask drift.
-
-Test classes (per `feedback_branch_count_before_approving`):
-
-  - test_coe_false_is_ignored                  — `continue-on-error: false`
-    has no tracker requirement. Exit 0.
-  - test_coe_true_with_open_recent_mc_passes   — coe true + adjacent
-    `# mc#1234` comment, issue open and 5 days old. Exit 0.
-  - test_coe_true_with_open_recent_internal    — adjacent `# internal#42`,
-    open, 1 day old. Exit 0.
-  - test_coe_true_no_comment_fails             — coe true with no
-    nearby tracker comment. Exit 1, names the file+line and the
-    required tracker shape.
-  - test_coe_true_comment_too_far_away_fails   — `# mc#1234` 5 lines
-    above the coe directive — outside the 2-line window. Exit 1.
-  - test_coe_true_closed_issue_fails           — issue exists but is
-    `state=closed`. Exit 1, names the issue.
-  - test_coe_true_too_old_issue_fails          — issue open but
-    `created_at` is 20 days ago. Exit 1, mentions the age cap.
-  - test_coe_true_at_14d_passes                — boundary: exactly 14d
-    old. Inclusive. Exit 0.
-  - test_coe_true_at_15d_fails                 — boundary: 15d old.
-    Exclusive. Exit 1.
-  - test_coe_true_api_404_fails                — referenced issue
-    doesn't exist (deleted or typo). Exit 1.
-  - test_coe_true_api_403_skips                — token-scope issue,
-    graceful-degrade per Tier 2a contract: exit 0 with ::error::,
-    do NOT red-X every PR over auth.
-  - test_two_coe_true_one_violating            — multi-violation
-    aggregation: one passes, one fails → exit 1, all violations
-    surfaced (not short-circuited).
-  - test_coe_true_with_comment_AFTER_directive — comment on the line
-    below the directive (within 2 lines) still satisfies. Exit 0.
-  - test_coe_value_quoted_string_true_caught   — `continue-on-error: "true"`
-    parses to the string "true" via PyYAML which is truthy but NOT
-    boolean `True` — the lint catches the IR `True` from
-    `continue-on-error: true`, and also flags string `"true"` because
-    Gitea's evaluator coerces it.
-
-Stubs:
-  - `subprocess.run` is NOT used (this lint reads only files +
-    HTTP); `urllib.request.urlopen` IS stubbed via monkeypatch on
-    the module-level `api()` to drive issue-API responses.

-`all-required` sentinel's `needs:` block must EITHER:
-
-  - Touch both atomically in the same PR (preferred), OR

-The class this lint exists to prevent: PR#665 (interim
-continue-on-error: true on platform-build) + PR#668 (sentinel-exempt)
-were designed-as-a-pair but merged solo — #665 landed at 04:47Z, #668

-prod branch enumerated):
-
-  - test_diff_touches_neither_passes              — diff is in ci.yml
-    but neither continue-on-error nor all-required.needs is touched.
-    PR is exempt. Exit 0.

-    the same PR. Atomic. Exit 0.
-  - test_diff_touches_coe_only_no_pair_fails      — continue-on-error
-    flipped without sentinel-needs change AND no `Paired: #NNN`
-    reference anywhere. Exit 1.
-  - test_diff_touches_needs_only_no_pair_fails    — sentinel `needs:`
-    changed without `continue-on-error` change AND no pair reference.

-  - test_diff_touches_coe_only_pair_in_body       — coe changed, no

-The lint receives base SHA + head SHA via env (set by the workflow

-sides without a separate clone. Tests stub `subprocess.run` to drive

-"""Tests for `.gitea/scripts/lint_required_context_exists_in_bp.py` — Tier 2g lint.
-
-Structural enforcement of internal#350 Tier 2g: when a PR adds a NEW
-commit-status emission (a workflow's `name:` + a new job-key/name pair
-that didn't exist on the base side), the PR must EITHER:
-
-  (a) Include a `# bp-required: yes` directive comment on the workflow
-      AND the new context must already be in
-      `branch_protections/<branch>.status_check_contexts`, OR
-
-  (b) Include a `# bp-required: pending #NNN` directive (acknowledged
-      asymmetry with a tracking issue), OR
-
-  (c) Include a `# bp-exempt: <reason>` directive (informational job,
-      not intended to be a required gate).
-
-Default (no directive on a new emitter) = FAIL.
-
-The class this prevents
------------------------
-PR#656 added `CI / all-required (pull_request)` as a sentinel context
-that workflows emit, but BP did NOT list it — so when `platform-build`
-failed, `all-required` failed, but BP let the PR merge anyway. Cascade
-to mc#664. With Tier 2g, PR#656 would have been blocked until either
-the BP PATCH ran alongside OR the author marked the emission with a
-`bp-required: pending #NNN` directive.
-
-Test classes (per `feedback_branch_count_before_approving`):
-
-  - test_no_new_emissions_skips                   — diff doesn't add any
-    new emitter; pass.
-  - test_new_emission_with_bp_required_yes_in_bp  — directive set AND
-    BP lists the context; pass.
-  - test_new_emission_with_bp_required_yes_not_in_bp — directive set
-    BUT BP doesn't list; fail.
-  - test_new_emission_with_bp_required_pending    — `# bp-required:
-    pending #800` directive references an open tracker; pass.
-  - test_new_emission_with_bp_exempt              — `# bp-exempt:
-    informational` directive; pass.
-  - test_new_emission_no_directive_fails          — no directive on a
-    new emission; fail with the 3-option fix-hint.
-  - test_modified_workflow_with_new_job_is_new    — pre-existing
-    workflow gains a new job with a new name → counted as new
-    emission. Apply rule.
-  - test_modified_workflow_job_renamed_is_new     — same workflow,
-    same job-key, but job `name:` changed → counted as new emission
-    (the OLD context name disappears; the NEW one needs validation).
-  - test_unrelated_workflow_edit_is_not_new       — edit a comment in
-    an existing emitter; no new context introduced; pass.
-  - test_api_403_skips_gracefully                 — BP read 403; exit 0
-    with stderr ::error::.
-  - test_directive_must_be_in_workflow_yml        — directive in PR
-    body alone is NOT sufficient; the comment must live in the
-    workflow file so future scheduled Tier 2f runs can see it.

-Structural enforcement of `feedback_path_filtered_workflow_cant_be_required`:
-no workflow whose status-check context is in `branch_protections/main`
-`status_check_contexts` may use `paths:` or `paths-ignore:` filters in its
-`on:` block. A path-filtered workflow silently does not fire on a PR whose
-diff doesn't touch the filter — Gitea treats that as `pending` forever,
-not `skipped`-as-`success`, so the gate degrades to an indefinite block.
-Worse, a docs-only PR could never satisfy a required check whose filter
-excludes docs paths, and the protected branch becomes unreachable.
-
-Five test classes:
-  - test_no_required_workflows_succeeds — empty status_check_contexts → exit 0
-  - test_required_workflow_no_paths_passes — required workflow with no
-    paths filter → exit 0
-  - test_required_workflow_with_paths_filter_fails — required workflow
-    with `paths: ['**.go']` → exit 1, error names workflow
-  - test_required_workflow_with_paths_ignore_fails — same shape for
-    `paths-ignore`
-  - test_unknown_required_context_warns_not_fails — context whose
-    workflow file is missing → warn, do NOT fail (graceful — could be a
-    cross-repo context name or a workflow renamed mid-PR; the lint is for

-Also covers the workflow-name → file-path mapping (parses the
-`<workflow_name> / <job_name> (<event>)` context format) and the
-multi-event `on:` block edge cases (paths under `on.push` vs `on.pull_request`
-vs top-level `on.paths`).

-Dependencies: stdlib + PyYAML (already required by the script itself).
-No network. No live Gitea calls — `api()` is stubbed.

-// goroutines that could block on request-body reads.

+// These test the fix for issue #159: when proxyA2ARequest returns an error but we have a
+// non-empty response body with a 2xx status code, executeDelegation must treat it as success.
+// The error is a delivery/transport error (e.g., connection reset after response was received).
+// Previously, executeDelegation marked these as "failed" even though the work was done,
+// causing retry storms and "error" rendering in canvas despite the response being available.
+//
+// Test strategy: spin up a mock A2A agent server, set up the source/target DB rows, call
+// executeDelegation directly, and verify the activity_logs status and delegation status.

+//     POST-FIX: the executeDelegation new condition sees status=200, body=<partial>, err!=nil
+//     and routes to handleSuccess immediately.
+//
+// The key pre/post-fix difference: pre-fix, executeDelegation received status=0 (hardcoded)
+// even when the server sent 200, so the condition always failed. Post-fix, status=200 is
