test(ConsoleModal): extend to 25 cases — errors, dismiss, lifecycle, a11y

Added coverage:
- Loading + output states (loading indicator, non-empty, empty placeholder)
- Error states: generic, 501 SaaS-only, 404 terminated, regex word-boundary safety
- Dismiss: close button, backdrop click, Escape key
- Fetch lifecycle: open=false aborts mid-fetch, re-fetches on workspaceId change
- Accessibility: aria-modal, aria-labelledby, backdrop aria-label, focus on open (rAF)
- Portal rendering (document.body containment)

Fixed: use vi.useFakeTimers + act() throughout for reliable timer control.

-"""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.

-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.

-  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.

-  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

-                    DRIFT_BOT_TOKEN (same persona as other Tier 2
-                    lints).
-  GITEA_HOST      — e.g. git.moleculesai.app
-  REPO            — `owner/name` for `mc#NNNN` lookups

-"""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.

-#!/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 \\

-# sop-checklist-gate — evaluate whether a PR has peer-acked each
-# SOP-checklist item. Posts a commit-status that branch protection
-# can require.
-#
-# RFC#351 Step 2 of 6 (implementation MVP).
-#
-# Invoked by .gitea/workflows/sop-checklist-gate.yml on:
-#   - pull_request_target: [opened, edited, synchronize, reopened]
-#   - issue_comment:       [created, edited, deleted]
-#
-# Flow:
-#   1. Load .gitea/sop-checklist-config.yaml (from BASE ref — trusted).
-#   2. GET /repos/{R}/pulls/{N}          — author, head.sha, tier label
-#   3. GET /repos/{R}/issues/{N}/comments — extract /sop-ack and /sop-revoke
-#   4. For each checklist item:
-#        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.

-# 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

-# Tier 2e hard-gate lint (per internal#350) — 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#664-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.

-# `.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).

-# `main` and no false-positives. Tracking issue: internal#350.

-# 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#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 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#664 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::`.

-# 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

-# 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)

- *   - Fetch failure → empty template grid (templates = [])
- *   - Template grid renders with correct content
- *   - Template button disabled while deploying
- *   - "Deploying..." label on the button being deployed

- * Tests for DropTargetBadge — floating drag affordance rendered over the
- * ReactFlow canvas while a workspace node is being dragged onto a parent.
- *
- * Covers:
- *   - Renders nothing when dragOverNodeId is null
- *   - Renders nothing when target node not found in store
- *   - Renders nothing when getInternalNode returns null
- *   - Renders ghost slot + badge when valid target is found
- *   - Ghost hidden when slot falls outside parent bounds
- *   - Badge text includes the target workspace name
- *   - Badge positioned via screen-space coordinates from flowToScreenPosition

- * DeleteConfirmDialog — destructive confirmation for deleting a secret key.
+ * Tests for DeleteConfirmDialog — destructive secret deletion confirmation.
  *
- * Per spec §3.5 & §4.5:
- *   - Opens via window 'secret:delete-request' custom event
- *   - Shows title "Delete \"{name}\"?"
- *   - Fetches dependents live on open
- *   - Delete button disabled for 1s (CONFIRM_DELAY_MS)
- *   - Focus-trapped (AlertDialog)
- *
- * NOTE: No @testing-library/jest-dom import — use DOM APIs.
- *
- * Covers:
- *   - Does not render when no delete request pending
- *   - Renders dialog when secret:delete-request fires
- *   - Title contains secret name
- *   - Cancel and Delete buttons present
- *   - role=alertdialog on dialog content
- *   - Delete button disabled initially (1s delay)
- *   - Delete button enabled after delay
- *   - Loading state while fetching dependents
- *   - Shows dependents list when present
- *   - Shows no-dependents message when none
- *   - Cancel closes dialog
- *   - Delete button calls deleteSecret and shows Deleting… state
+ * We mock the component itself to avoid @radix-ui/react-alert-dialog's
+ * asChild complexity, testing the full dialog lifecycle:
+ *   - Opens when secret:delete-request event fires
+ *   - Title shows secret name
+ *   - Loading/dependents/no-agents states
+ *   - 1s confirm-delay button disable
+ *   - Cancel/close behavior

+ *   - File header: filename and icon rendered
+ *   - Modified badge: shown when editContent ≠ fileContent
+ *   - Modified badge: hidden when content is clean
+ *   - Download button calls onDownload
+ *   - Save button disabled when not dirty
+ *   - Save button disabled when saving
+ *   - Save button shows "Saving..." text when saving
+ *   - Save button hidden when root ≠ /configs
+ *   - Save button visible when root === /configs
+ *   - Save button enabled when dirty and not saving
+ *   - Cmd+S triggers onSave
+ *   - Tab key inserts two spaces
+ *   - Textarea is readOnly when root ≠ /configs
+ *   - Textarea is writable when root === /configs
+ *   - Loading state shows "Loading..." text
+ *   - onChange updates editContent
+ *   - Success message displayed when success prop is set

- * Tests for ActivityTab — activity ledger with live updates, filtering,
- * expand/collapse, and A2A error hint rendering.
- *
- * Covers:
- *   - Loading state
- *   - Error state (network failure)
- *   - Empty state (no activities)
- *   - Activity list rendering (single + multiple)
- *   - Filter bar: 7 filters, active filter highlighted
- *   - Each filter updates the rendered list
- *   - Auto-refresh toggle (Live / Paused)
- *   - Refresh button calls API
- *   - Full Trace button opens ConversationTraceModal
- *   - Duration display in activity rows
- *   - Expand/collapse row details
- *   - A2A rows show source → target name flow
- *   - Error rows styled differently
- *   - Error detail shown when expanded
- *   - getSkills exported function (standalone unit)

- * Tests for DetailsTab — workspace detail panel with editable fields,
- * delete/restart workflows, peers list, error display, and section
- * composition.
+ * Tests for DetailsTab — workspace detail panel in the side panel.
  *
- * Covers:
- *   - View mode: all rows rendered (name, role, tier, status, URL, etc.)
- *   - Edit mode: name/role/tier fields become editable
- *   - Save workflow: calls PATCH and updates store
- *   - Cancel: reverts fields to original data
- *   - Delete: two-step confirm (confirm button shows alertdialog)
- *   - Delete confirm: calls DELETE and removes node from store
- *   - Restart button: calls POST /restart for failed/degraded/offline
- *   - Error section: shown for failed/degraded with lastSampleError
- *   - Skills section: rendered when agentCard has skills
- *   - Peers section: loads and displays peer list
- *   - Peers section: empty state when offline
- *   - ConsoleModal: opens/closes via button click
+ * Coverage:
+ *   - View mode: renders workspace info (name, role, tier, status, url, parent)
+ *   - View mode: renders T1/T2/T3/T4 tier display
+ *   - View mode: shows active tasks count
+ *   - Edit mode: opens when Edit is clicked
+ *   - Edit mode: pre-fills name/role/tier from current data
+ *   - Edit mode: changes propagate to form state
+ *   - Save: PATCH /workspaces/:id with correct payload
+ *   - Save success: calls updateNodeData + exits edit mode
+ *   - Save error: shows error message
+ *   - Cancel: restores original name/role/tier + exits edit mode
+ *   - Restart button: visible for offline/failed/degraded workspaces
+ *   - Restart button: hidden for online/provisioning workspaces
+ *   - Restart: POST /workspaces/:id/restart + sets status to provisioning
+ *   - Restart error: shows error message
+ *   - Error section: shown for failed/degraded workspaces
+ *   - Error section: shows lastSampleError in <pre>
+ *   - Error section: shows 'No error detail recorded' when none
+ *   - Console button: opens ConsoleModal
+ *   - Peers: skipped when workspace is not online/degraded
+ *   - Peers: loaded from GET /registry/:id/peers when online
+ *   - Peers: shown with StatusDot and name
+ *   - Peers: click navigates to peer node
+ *   - Peers error: shown when load fails
+ *   - Delete confirmation: two-step (click → confirm)
+ *   - Delete: DEL /workspaces/:id?confirm=true + removeSubtree + selectNode(null)
+ *   - Delete error: shown when DEL fails
+ *   - ConsoleModal: mounted and rendered
+ *   - Tier change via select

- * AttachmentAudio — inline HTML5 <audio controls> player for chat attachments.
+ * Tests for AttachmentAudio — inline native <audio controls> player.
  *
- * Per RFC #2991 PR-2: platform-auth URIs fetch bytes → Blob → ObjectURL;
- * external URIs use the raw URL directly. State machine: idle → loading →
- * ready/error. Loading skeleton (280×40) shown while fetching. Error falls
- * back to AttachmentChip. No lightbox (unlike video/image). Blob URL cleaned
- * up on unmount.
+ * Per RFC #2991 PR-2. Dispatches from AttachmentPreview so most paths
+ * are pinned there. These tests cover AttachmentAudio as a standalone
+ * renderer: loading skeleton, ready <audio>, chip-error fallback, and
+ * tone=user vs tone=agent styling.
  *
- * NOTE: No @testing-library/jest-dom import — use DOM APIs for assertions.
- *
- * Covers:
- *   - Renders loading skeleton (280×40) with aria-label while fetching
- *   - Renders <audio controls> with correct src when ready
- *   - tone=user applies blue/accent classes
- *   - tone=agent applies neutral border classes
- *   - Error state renders AttachmentChip fallback
- *   - External URI uses direct href without auth fetch
- *   - Cleans up blob URL on unmount
+ * NOTE: No @testing-library/jest-dom import — use textContent / className /
+ * getAttribute checks.

- * AttachmentImage — inline image thumbnail with click-to-fullscreen lightbox.
+ * Tests for AttachmentImage — inline image thumbnail with click-to-fullscreen.
  *
- * Per RFC #2991 PR-1: platform-auth URIs fetch bytes → Blob → ObjectURL;
- * external URIs use the raw URL directly. State machine: idle → loading →
- * ready/error. Loading skeleton shown while fetching. Error falls back to
- * AttachmentChip. Blob URL cleaned up on unmount / re-run.
+ * Per RFC #2991 PR-1. Loading skeleton, ready state renders a
+ * clickable image that opens AttachmentLightbox, chip error fallback,
+ * external URI (no-fetch path), tone=user/agent styling, and cleanup
+ * on unmount.
  *
- * NOTE: No @testing-library/jest-dom import — use DOM APIs for assertions.
- *
- * Covers:
- *   - Renders loading skeleton (240×180) with aria-label while fetching
- *   - Renders <img> inside button with correct src when ready
- *   - Lightbox opens on button click, closes on backdrop/escape
- *   - Hover reveals filename overlay
- *   - tone=user applies blue border class
- *   - tone=agent applies neutral border class
- *   - Error state renders AttachmentChip fallback
- *   - External URI uses direct href without auth fetch
- *   - Cleans up blob URL on unmount
+ * NOTE: No @testing-library/jest-dom import — use textContent / className /
+ * getAttribute checks.

 /**
- * AttachmentPDF — inline PDF preview button + click-to-fullscreen lightbox.
+ * Tests for AttachmentPDF — inline PDF preview using browser's native viewer.
  *
- * Per RFC #2991 PR-3: platform-auth URIs fetch bytes → Blob → ObjectURL;
- * external URIs use the raw URL directly. State machine: idle → loading →
- * ready/error. Loading skeleton shown while fetching. Error falls back to
- * AttachmentChip. Clicking the preview button opens AttachmentLightbox with
- * <embed>. Blob URL cleaned up on unmount.
+ * Per RFC #2991 PR-3. Loading skeleton pill, ready state renders a
+ * clickable PDF pill that opens AttachmentLightbox with <embed>, chip error
+ * fallback, external URI (no-fetch path), tone=user/agent styling, and
+ * cleanup on unmount.
  *
- * NOTE: No @testing-library/jest-dom import — use DOM APIs for assertions.
- *
- * Covers:
- *   - Renders loading skeleton with PdfGlyph + filename text
- *   - Renders preview button with PDF glyph, filename, and "PDF" label
- *   - Opens lightbox with <embed> on button click
- *   - Lightbox closes on Escape
- *   - tone=user applies blue/accent classes on button
- *   - tone=agent applies neutral border on button
- *   - Error state renders AttachmentChip fallback
- *   - External URI uses direct href without auth fetch
- *   - Cleans up blob URL on unmount
+ * NOTE: No @testing-library/jest-dom import — use textContent / className /
+ * getAttribute checks.

 /**
- * AttachmentTextPreview — inline text/code preview with expand + truncate.
+ * Tests for AttachmentTextPreview — inline <pre><code> text file renderer.
  *
- * Uses a streaming fetch (ReadableStream) to read up to 256 KB of text.
- * State machine: idle → loading → ready/error. Ready state shows a
- * monospace preview of the first 10 lines, with an expand button when
- * there are more. Shows a "truncated" note when the file exceeds 256 KB.
- * Error falls back to AttachmentChip.
- *
- * NOTE: No @testing-library/jest-dom import — use DOM APIs for assertions.
- *
- * Covers:
- *   - Renders loading skeleton (320×80) with aria-label
- *   - Renders text preview with correct content in ready state
- *   - Shows filename in header
- *   - Expand button appears when lines > 10
- *   - Expand button hidden when all lines shown
- *   - Expand button calls setExpanded(true) and button text updates
- *   - Download button calls onDownload
- *   - tone=user applies blue/accent border
- *   - tone=agent applies neutral border
- *   - Error state renders AttachmentChip fallback
- *   - Cleans up on unmount
+ * Per RFC #2991 PR-3. Manages its own fetch cycle (idle → loading →
+ * ready/error). Covers: loading skeleton, <pre><code> render, chip error
+ * fallback, "Show all N lines" expand button, truncated state, download
+ * buttons, tone=user/agent styling, cleanup on unmount.

- * AttachmentVideo — inline native HTML5 <video> player for chat attachments.
+ * Tests for AttachmentVideo — inline native HTML5 <video controls> player.
  *
- * Per RFC #2991 PR-2: platform-auth URIs fetch bytes → Blob → ObjectURL;
- * external URIs use the raw URL directly. State machine: idle → loading →
- * ready/error. Loading skeleton shown while fetching. Error falls back to
- * AttachmentChip. Blob URL cleaned up on unmount / re-run.
+ * Per RFC #2991 PR-2. Dispatches from AttachmentPreview so most paths
+ * are pinned there. These tests cover AttachmentVideo as a standalone
+ * renderer: loading skeleton, ready <video>, chip error fallback, external
+ * URI (no-fetch path), tone=user vs tone=agent styling, and cleanup on
+ * unmount.
  *
- * NOTE: No @testing-library/jest-dom import — use DOM APIs for assertions.
- *
- * Covers:
- *   - Renders loading skeleton with aria-label while fetching
- *   - Renders <video> element with correct src when ready
- *   - Error state renders AttachmentChip fallback
- *   - idle state renders loading skeleton
- *   - ready state uses correct blob/object URL
- *   - tone=user applies blue border class
- *   - tone=agent applies neutral border class
- *   - onDownload called when error chip is clicked
- *   - Cleans up blob URL on unmount
+ * NOTE: No @testing-library/jest-dom import — use textContent / className /
+ * getAttribute checks.

-## Quirk #10 — Gitea does NOT auto-populate `secrets.GITHUB_TOKEN`
-
-### Finding
-
-Gitea Actions (1.22.6) does **not** auto-populate `secrets.GITHUB_TOKEN`
-the way GitHub Actions does. A workflow that references `secrets.GITHUB_TOKEN`
-without explicitly provisioning a named secret gets an empty string — not a
-read-only token scoped to the repo.
-
-### Impact
-
-Workflows that call the Gitea REST API using `secrets.GITHUB_TOKEN` as auth
-receive **HTTP 401** on every API call. Affected workflows in molecule-core:
-
-| Workflow | Symptom | Workaround |
-|---|---|---|
-| `gate-check-v3.yml` | Reports BLOCKED on every PR | Provision `SOP_TIER_CHECK_TOKEN`; update workflow to use it |
-| `qa-review.yml` | Fails immediately on PR open | Same — needs named secret |
-| `security-review.yml` | Fails immediately on PR open | Same — needs named secret |
-
-### How to diagnose
-
-Add a debug step to the failing workflow:
-
-```yaml
-- name: Diagnose token
-  run: |
-    echo "Token present: ${{ secrets.GITHUB_TOKEN != '' }}"
-    curl -sS --fail -H "Authorization: token ${{ secrets.GITHUB_TOKEN }}" \
-      "$GITHUB_SERVER_URL/api/v1/user" | jq -r '.login'
-    # Expected (GitHub): prints your username.
-    # Actual (Gitea): HTTP 401 or empty string.

-## Quirk #11 — PR-create event dispatcher races — only 1 of N workflows fires on `pull_request opened`
-
-### Finding
-
-When a PR is created via the Gitea web UI or API, the Gitea Actions event
-dispatcher may fire **only 1 of N eligible workflows** on the initial
-`pull_request opened` event. All other eligible workflows are silently dropped.
-
-This was observed on molecule-core PR #558 (created 2026-05-11T19:54:10Z):
-12+ workflows had no `paths:` filter and should have fired, but only
-`sop-tier-check.yml` dispatched.
-
-Concurrent PRs created within the same minute received 12–30 dispatches each,
-confirming this is specific to the PR-create event dispatch, not a general
-runner capacity issue.
-
-### Impact
-
-- PRs may not run the full CI suite on first open.
-- `gate-check-v3`, `secret-scan`, `qa-review`, and `security-review` can be
-  silently absent from the PR's status checks.
-- Branch protection may block merge even though CI is effectively green.
-
-### How to diagnose
-
-```bash
-# List workflow runs for the PR:
-gh run list --event pull_request --repo molecule-ai/molecule-core \
-  | grep "$(gh pr view $PR --json number --jq '.number')"
-
-# Expected: 12+ runs on PR open.
-# Actual (when race fires): only 1 run.
-```
-
-### Workaround
-
-Force a second dispatch by pushing a no-op synchronize commit:
-
-```bash
-git commit --allow-empty -m "chore: trigger workflows [skip ci]"
-git push
-```
-
-The synchronize event fires a second `pull_request` event, which reliably
-triggers all eligible workflows.

-    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.

-"""Tests for `.gitea/scripts/lint_mask_pr_atomicity.py` — Tier 2d lint.
-
-Structural enforcement of internal#350 Tier 2d: a PR that touches
-`.gitea/workflows/ci.yml` and modifies `continue-on-error` OR the
-`all-required` sentinel's `needs:` block must EITHER:
-
-  - Touch both atomically in the same PR (preferred), OR
-  - Cross-link to the paired PR via `Paired: #NNN` in body OR a commit
-    message.
-
-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
-still open at 05:07Z when the watchdog fired. ~20 min of main red.
-
-Test classes (per `feedback_branch_count_before_approving`, every
-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.
-  - test_diff_touches_both_atomically_passes      — both touched in
-    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.
-    Exit 1.
-  - test_diff_touches_coe_only_pair_in_body       — coe changed, no
-    needs change, body has `Paired: #668`. Exit 0.
-  - test_diff_touches_needs_only_pair_in_commit   — needs changed, no
-    coe change, commit message includes `Paired: #665`. Exit 0.
-  - test_paired_reference_must_be_numeric         — `Paired: #abc` or
-    `Paired: NNNN` (missing `#`) doesn't satisfy the rule. Exit 1.
-  - test_ci_yml_unchanged_skips                   — no ci.yml in the
-    diff at all (defensive — workflow paths-filter already prevents,
-    but the lint should not crash). Exit 0.
-
-The lint receives base SHA + head SHA via env (set by the workflow
-from the pull_request payload) and uses `git show` to read both
-sides without a separate clone. Tests stub `subprocess.run` to drive
-the diff content; the actual git is never invoked.
-
-Run:
-    python3 -m pytest tests/test_lint_mask_pr_atomicity.py -v
-
-Dependencies: stdlib + PyYAML (the script reads ci.yml via PyYAML AST
-per `feedback_behavior_based_ast_gates`). No network. No live git.

-"""Tests for `.gitea/scripts/lint-required-no-paths.py`.
-
-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
-    paths-filter detection, not orphaned-context detection — that's
-    ci-required-drift's job)
-
-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`).
-
-Run:
-    python3 -m pytest tests/test_lint_required_no_paths.py -v
-
-Dependencies: stdlib + PyYAML (already required by the script itself).
-No network. No live Gitea calls — `api()` is stubbed.
