console: unify goal mode to no-time-limit only (port of 395dffb onto 37ba687)

DispatchSection keeps a single 'goal 模式' checkbox (the former
invincible option): checking it sends goal_mode=1 plus
no_time_limit=1. TaskDetailPanel drops the '无敌版' label.
Ported verbatim from feat-console-goal-unify commit 395dffb
(base 622c51e); console.html rebuilt from cloud/console-react
with npm run build:console (tsc+vite pass) and synced verbatim
from dist/index.html (sha256 daba1941...).

+"""Declarative agent definitions (harness alignment, v1).
+
+Zero third-party dependencies; standard library only.
+
+A definition is a versioned JSON document that bundles the fields a
+task already understands -- model, effort, approval, executor, plan --
+plus a human-written instruction block and a list of required skills.
+It is the Foundry-style "agent defined declaratively, harness runs
+the loop" idea, cut down to what this codebase can actually honour
+today, with every boundary written down instead of implied:
+
+* Resolution happens at task creation (``POST /tasks`` with an inline
+  ``agent`` object). Per field, an explicit body field wins over the
+  definition; a field absent from both stays NULL and follows the
+  existing worker-default chain. A definition that sets ``model``
+  therefore makes the task explicit for rule routing v0, and a
+  definition that leaves ``model`` empty leaves routing to the worker.
+* Instructions reach the model only as a marked header prepended to
+  the stored prompt (``[Agent: <name>]``), because the dispatch path
+  (``cloud/sandbox.py`` -> ``host.py dispatch``) has no
+  developerInstructions channel today. This is NOT claimed to be
+  ``developerInstructions``: it is visible in the stored prompt, in
+  the creation response, and in every later prompt read. Instructions
+  are rejected with goal tasks and coordinator tasks, where the
+  prompt is a goal or is never run as a model turn, so the header
+  cannot silently pollute a goal text or a coordinator parent.
+* Skills are validated against the ``cloud/skills/`` pack at parse
+  time (an unknown skill is a 400, never a silent drop). Seeding
+  itself stays worker-global (``--seed-skills`` seeds the whole pack
+  into the tenant codex-home); v1 does NOT claim per-agent seeding.
+  When seeding is off, a listed skill is recorded in the creation
+  response but is not guaranteed present at run time -- that is the
+  documented v1 boundary, not a bug to be discovered later.
+* Routing policy is deliberately NOT part of a definition in v1:
+  routing stays a worker-global policy (see ``cloud/models.py``).
+  Putting a routing object inside a definition would either be
+  silently dropped (a lie) or need a per-task policy column that does
+  not exist. A definition that contains ``routing`` / ``routing_policy``
+  is rejected, so a typo or a v2 idea cannot masquerade as v1 behaviour.
+* Unknown top-level or defaults keys are rejected for the same
+  reason: a declarative file must fail on typos, not silently ignore
+  them.
+
+v2 (this file, plus server/worker/sandbox/host changes) closes the
+three v1 boundaries that were explicitly left open:
+
+* Registry: definitions can live as files under repo-root ``agents/``
+  (``default_agents_dir()``) and be referenced by name
+  (``agent_name``) instead of only inline. The server never loads a
+  definition from a caller-supplied path; it only loads
+  ``<name>.json`` under the registry dir, with the traversal guard
+  in ``load_agent_definition``.
+* Persistence: ``tasks`` gains ``agent_name`` / ``agent_version`` /
+  ``agent_instructions`` columns (see ``migrate_tasks_table``), so
+  ``GET /tasks`` shows the definition identity and instructions, and
+  the worker no longer has to reconstruct them from a prompt header.
+* Real channel: for local/docker executors, instructions travel as
+  ``--developer-instructions`` on the host.py top-level command,
+  through ``sandbox`` into ``host.py dispatch`` ->
+  ``create_thread(developerInstructions=...)``. The stored prompt
+  stays clean. For the generic cloud executor, which has no such
+  channel, the worker falls back to the v1 marked header in the
+  in-memory dispatch prompt only (DB prompt stays clean) -- that
+  fallback is the documented cloud boundary, not a claim that the
+  cloud runner honours developerInstructions. Goal and coordinator
+  tasks still reject instructions in v2: the goal loop and the
+  coordinator parent do not pass instructions through, and silently
+  dropping them there would be worse than rejecting them.
+
+v3 (tools, this file plus server/worker changes) adds a ``tools``
+field, but deliberately as REQUIRED tools, not an allowlist:
+
+* A definition may declare ``tools`` from the MCP servers this
+  codebase actually seeds: ``websearch``, ``imagegen``,
+  ``playwright``. An unknown tool is a 400, never a silent drop.
+* The worker does NOT claim to block other tools. Blocking would
+  need a tool allowlist in ``create_thread`` (which does not exist)
+  or per-task codex-homes (tenant homes are per-project and shared,
+  and MCP seeding is worker-global), so an allowlist claim would be
+  false. What v3 does instead is fail fast on the opposite, silent
+  failure: a task that declares a required tool but whose tenant
+  codex-home config.toml has no ``[mcp_servers.<tool>]`` section
+  at dispatch time is marked failed before any model call, with the
+  missing tools named. The check runs only for tenant-isolated
+  Docker workers, where the tenant config.toml is the actual
+  availability record (worker flags alone would be wrong: a section
+  seeded earlier by another worker persists in the shared tenant
+  home). Local/cloud workers skip the check and are documented as
+  such, not as "tools verified".
+
+v9 (tool approvals, this file plus server/worker changes) adds a
+``tool_approvals`` field, and it is deliberately narrower than
+"per-tool approval enforcement" -- the execution layer cannot
+honour that today, and this track says so instead of claiming it:
+
+* Declaration: ``tool_approvals`` maps a known tool to one of
+  ``ask`` / ``auto`` / ``deny``. Unknown tools and unknown
+  policies are 400s. A tool declared both required (``tools``)
+  and ``deny`` is a 400: a task that must use a tool it must
+  never be allowed to use is a contradiction, not a policy.
+* What is NOT claimed: per-tool interception in host.py.
+  ``host.py _answer_server_request`` answers every elicitation
+  with one global switch (``approval == "auto"`` accepts,
+  anything else declines) and the elicitation message carries
+  no tool/server identity this codebase can rely on, so host
+  cannot tell which tool is asking. The approvals queue
+  (``cloud/approvals.py``) is record-only today: host runs in
+  a worker-spawned subprocess with no control-plane channel,
+  so there is no "ask the user" path at runtime. Credential
+  scope is NOT part of this field either: MCP credentials live
+  in the tenant codex-home config / env, per-project, not
+  per-task, and declaring a scope here without a channel to
+  enforce it would be the same kind of lie.
+* What IS executed: the declaration is validated at creation,
+  persisted (tasks.agent_tool_approvals, JSON object, NULL =
+  undeclared), echoed in GET and the creation response, and
+  at dispatch the worker audits the declaration together with
+  its effective outcome under today's host behaviour
+  (``effective_tool_approvals``): ``auto`` + host-auto accepts,
+  everything else declines, and ``ask`` is reported as
+  "decline (no ask channel)" -- never as "will ask". The
+  worker also re-checks the required+deny contradiction at
+  dispatch (defence in depth for rows written before v9 or
+  outside the API) and fails fast before any model call, in
+  the v3 tools-gate shape. Goal and coordinator tasks reject
+  tool_approvals at creation, like instructions: their turns
+  do not pass the declaration through, so accepting it there
+  would be a silent drop.

+"""Architecture-conformance checks for the control plane and for
+skill-driven projects (software-engineering skill, G2 frozen artefacts).
+
+Zero third-party dependencies; standard library only. This module
+imports no ``cloud.*`` module, so it can never violate the layer bans
+it enforces, and it can be reused verbatim against a skill project's
+own directory tree (see ``check_skill_project``).
+
+The four checks, each with a stated rule and a stated reason:
+
+1. Contract version (``check_contract_version``). Rule mirrors the
+   skill's contract-freeze change protocol: after freeze, a version
+   change is allowed only with a coordinator-approved change record
+   that names backward compatibility, the affected clients, and (for
+   a breaking change) a regression task per affected client; the
+   version must advance by exactly one. Reason: a silent contract
+   drift is how parallel client threads diverge; the protocol is the
+   only sanctioned path, so the check enforces the protocol instead
+   of merely documenting it.
+
+2. Forbidden directories (``is_within`` / ``check_task_writes``).
+   Rule reuses the two directory definitions that already exist and
+   invents no third one: on the control plane a task's own directory
+   is its tenant work directory (``worker._tenant_dirs`` ``work``);
+   in a skill project a client thread's own directory is its
+   ``apps/<client>/`` tree. Any write outside the own directory --
+   including ``..`` escapes and symlink escapes, both resolved before
+   comparison -- is a violation. Reason: cross-directory writes are
+   how one tenant/client corrupts another's worktree.
+
+3. Forbidden imports (``check_layer_imports``). Bans were chosen by
+   auditing the current tree, not by wishful layering; every ban
+   below passes on the baseline, and the repo-level test pins that:
+
+   - Foundation modules (``db``, ``models``, ``queue``,
+     ``logging_config``) must not import orchestration/service
+     modules (``server``, ``worker``, ``pr_exec``, ``webhooks``,
+     ``autoscaler``, ``cost``). Reason: the foundation is imported
+     by everything; an upward import is a cycle waiting to happen
+     and drags service state into pure helpers.
+   - The execution module (``sandbox``) must not import persistence
+     or orchestration (``db``, ``server``, ``worker``, ``cost``,
+     ``auth``, ``pr``, ``pr_exec``, ``webhooks``). Reason: executors
+     must stay swappable and testable with fake runners; decisions
+     about mounts and networks arrive as arguments, not by reading
+     the database.
+   - No cloud module except the driver-adjacent ones (``db``,
+     ``backup``, ``migrations``) may open a database connection
+     directly (``sqlite3.connect`` or any ``psycopg*`` import).
+     Service modules must obtain connections through
+     ``cloud.db.connect`` or a Store. Reason: the backend switch
+     (sqlite/postgres) lives in exactly one place; a direct driver
+     call bypasses it. Deliberately NOT banned: ``server.py``'s use
+     of ``sqlite3.Row`` / ``sqlite3.IntegrityError`` as type adapters
+     on connections obtained from ``cloud.db`` -- that is adaptation,
+     not a bypass, and banning it would fail the baseline for no
+     safety gain. The test asserts the narrow form (no ``connect``
+     call, no driver import) rather than the broad form.
+
+   Only static ``ast`` imports are seen; dynamic imports
+   (``importlib``) are out of scope and are noted, not claimed.
+
+4. Frozen stack (``check_frozen_stack``). Rule mirrors the skill's
+   G2 rule "frozen stack must not be swapped mid-flight": a client
+   whose stack entry changes, or disappears, after freeze fails
+   unless an approved change record covers it; adding a brand-new
+   client (no frozen entry) is an addition, not a swap, and passes.
+   Reason: the shared core is built against the frozen table; a
+   mid-flight swap silently invalidates it.
+
+All checkers return plain data (dicts/lists), never raise for a
+violation, so CI can report every violation in one run instead of
+stopping at the first.

+"""Lifecycle hook policy for the task-attempt ledger (audit gap 3
+follow-up: "which dispatch counts as an attempt, and who judges
+``is_defect``").
+
+This module is the CANONICAL policy text. The same policy is
+restated (shorter) in ``docs/arch-conformance-metrics.md`` and
+pinned by ``cloud/tests/test_attempt_hook.py``; if the three ever
+disagree, this module wins and the other two must be fixed.
+
+The problem it solves: audit gap 3 built the ledger but
+deliberately left the writer unconnected, because a naive writer
+-- one row per worker execution -- misclassifies exactly twice:
+it counts a platform auto-resume as an attempt, and it counts a
+transient retry as a defect. This module fixes the writer's
+trigger, not the ledger's math: ``aggregate_attempts`` is
+untouched by the hook (its only change in this track is the
+correction-row rule in ``attempt_ledger.py``), and the cost
+dual-column code (``cloud.cost``) is untouched entirely.
+
+POLICY (each rule is enforced in code below, not just prose):
+
+1. One counted dispatch = one row, at most. A dispatch that the
+   hook counts writes EXACTLY ONE ledger row, when its outcome is
+   known (terminal ``completed`` / ``failed`` / ``interrupted``,
+   or the goal-conversion case in ``worker.run_one``), with
+   ``is_defect=False`` always (rule 6). A dispatch that the hook
+   does not count writes NO row at all -- not even an
+   ``interrupted`` row -- so an uncounted dispatch can never
+   create the ledger table as a side effect.
+
+2. What counts as one attempt -- a logical agent round, not a
+   worker execution:
+   - First dispatch of a task: counts (``first_or_human_retry``).
+     It is the task's first agent round.
+   - Human ``/retry`` of a failed/interrupted/merge-failed task:
+     counts (same kind). A retry is a human-initiated new round:
+     new model work, new result, new cost. The server endpoint
+     leaves no marker behind, so the worker cannot distinguish a
+     retry from a first dispatch -- and does not need to, because
+     both count.
+   - Human ``/continue`` with a new message: counts
+     (``human_continue``). The message starts a new round on the
+     same session thread. Non-goal tasks and goal tasks opening a
+     NEW goal loop (``_resume_kind == "new-goal"``) are both here.
+   - Human breakpoint resume (``/goal-resume``, or ``/continue``
+     on an old-verify goal task, i.e. ``_resume_kind ==
+     "breakpoint"``): counts (``breakpoint_resume``) -- but as
+     the SAME logical round's row, not as an extra attempt. The
+     fragment that was interrupted wrote only an excluded
+     ``interrupted`` row (gap 3 rule), so the resume's terminal
+     row is the round's single counted row. A resume that ends
+     interrupted again writes only another excluded row: the
+     round is still pending, and still contributes zero counted
+     attempts. Rationale: one goal loop = one attempt, however
+     many executions the loop took; the interruption history
+     stays visible in the ``interrupted`` rows and in
+     ``auto_resume_count`` / audit / task_steps, not in the
+     attempt count. EXCEPTION (ordering, rule 4): when the
+     resume was itself platform-triggered, the platform marker
+     wins and the dispatch does NOT count -- a platform goal
+     auto-resume and a human goal-resume are the same loop
+     continuation, but only the human one is attributed to the
+     agent. That asymmetry is deliberate and uniform with the
+     platform rule below; flipping it is the listed user
+     decision, not a silent default.
+   - Coordinator parent dispatch: does NOT count
+     (``coordinator_orchestration``). The parent runs no model
+     round (``cost_record_id`` is None) and its terminal status
+     is an aggregate of its children; each child records its own
+     row through its own dispatch. Counting the parent would
+     double-count orchestration as an agent attempt.
+   - Platform auto-resume dispatch (worker
+     ``auto_resume_interrupted`` requeue, goal or non-goal):
+     does NOT count (``platform_auto_resume``). This is the
+     default the gap-3 track demanded, and it is UNIFORM: every
+     platform requeue is excluded, whether it continues a goal
+     loop or fresh-runs a non-goal task. Rationale: the platform
+     killed the previous execution and re-ran it without any
+     human or coordinator decision; attributing that execution
+     to the agent would punish platform instability in an
+     agent-quality rate. TRADE-OFF, STATED NOT HIDDEN: a task
+     whose terminal outcome came ONLY from platform dispatches
+     stays unknown in the ledger (no counted row), so it is
+     excluded from rate denominators -- the rates describe
+     tasks whose terminal outcome came from a human/first
+     round. The platform reruns themselves are NOT lost: they
+     are recorded in ``tasks.auto_resume_count``, the
+     ``worker_auto_resumed`` audit events, and the
+     ``task_steps`` ``auto_resume`` rows. The rejected
+     alternative was a separately marked ledger row that is
+     excluded from denominators: same denominator outcome, but
+     a second row kind, a new column, and aggregate exclusion
+     logic, for co-location only. If a future policy wants
+     platform completions counted as loop completions, the flip
+     is one line in ``classify_dispatch`` (platform + breakpoint
+     -> counted) plus tests -- it is listed as a user decision
+     in the track summary, not silently decided here.
+   - Pre-execution gate failures: do NOT count. A dispatch that
+     never reached the model -- missing key, repository
+     resolution failure, quota gate, goal-rounds cap, gateway
+     preparation failure -- is an admission rejection, not an
+     attempt. It writes no row (and no cost record either, which
+     is the existing behaviour); it stays visible in audit
+     (``worker_missing_key`` / ``worker_repo_failed`` /
+     ``worker_quota_stop`` / ``worker_goal_cap_rejected`` /
+     ``worker_gateway_failed``).
+   - Dispatches that never ran (budget gate, no ready task,
+     claim lost to another worker): do NOT count and are not
+     even classified -- ``run_one`` returns before the hook
+     runs, and no marker is consumed (see rule 4).
+
+3. Transient retries inside one dispatch are NOT new attempts.
+   The worker's ``max_retries`` loop, its one real fallback
+   re-run, its goal "already exists" breakpoint fallback, and
+   its follow-up drain all run inside a single ``run_one``
+   dispatch, share one cost aggregate, and produce ONE ledger
+   row: the dispatch's terminal outcome. An inner failure that
+   is later retried successfully leaves no failure row behind;
+   an inner failure that exhausts retries leaves one failure
+   row, not N. This is enforced by placement (the hook is
+   called once per dispatch, at ``run_one``'s terminal points)
+   rather than by counting executions.
+
+4. Platform identification -- the marker mechanism. The worker
+   that requeues a task is not necessarily the worker that later
+   claims it, so the origin must survive in the database, not in
+   memory. ``auto_resume_interrupted`` writes one marker row
+   (``task_attempt_origin_markers``) in the SAME transaction as
+   the requeue, with ``queued_at`` equal to the ``updated_at``
+   the requeue writes. ``run_one`` captures the queued task's
+   ``updated_at`` BEFORE claiming (claim overwrites it), and
+   after a successful claim consumes the marker ONLY if
+   ``queued_at`` still matches. Any intervening human action
+   (cancel, retry, continue) rewrites ``updated_at``, so a stale
+   marker can never misclassify a later human round: on
+   mismatch the marker is deleted as stale and the dispatch is
+   classified by its own fields. A claim that loses the race
+   consumes nothing, so the winning worker still sees its
+   marker. Marker writes and reads happen ONLY when the hook is
+   enabled; with the hook off, ``auto_resume_interrupted``
+   writes no marker and ``run_one`` reads none, so off behaviour
+   is byte-identical to gap 3 (no new table, no new row).
+   Marker-table creation is a write-path-only step, like the
+   ledger table itself; the read path (``GET /metrics-report``)
+   never touches it.
+
+5. Switch. ``Worker(attempt_ledger_hook=False)`` (CLI
+   ``--attempt-ledger-hook``), default OFF. OFF means: no ledger
+   row, no marker row, no marker-table creation, no ledger-table
+   creation from the worker -- exactly gap 3's "explicit calls
+   only" behaviour, including old tasks still returning ``None``
+   (unknown, not 0) and the read endpoint never creating a
+   table. ON means rules 1-4 apply. Enabling the hook
+   mid-flight has one documented edge: a task requeued by
+   auto-resume WHILE the hook was off carries no marker, so its
+   next dispatch counts as a human/first round (one extra
+   counted row for that in-flight task, once). That is the
+   fail-safe direction (a human round is the common case), and
+   it self-heals: every later requeue writes a marker.
+
+6. ``is_defect`` -- who judges, and how a wrong judgement is
+   fixed. The worker hook NEVER judges a defect: it always
+   records ``is_defect=False``. A failed dispatch is not a
+   defect (transient failures, quota stops, and cancelled rounds
+   all fail without being defects), and the worker cannot tell
+   a transient failure from a defect round at runtime -- so it
+   must not guess. The ONLY defect judgements in the ledger are
+   explicit ones, made at record time by an explicit recorder:
+   a human maintainer (or a coordinator review) calling
+   ``record_attempt`` / ``record_correction`` directly with
+   ``is_defect=True`` and a category. The bar for that authority
+   is maintainer-level (``approve_merge``, the same bar as
+   ``/retry``: both spend model money and move decision-grade
+   rates). A defect judgement made in error is corrected ONLY by
+   appending a correction row (``record_correction``): the old
+   row is never updated or deleted, corrections apply in
+   attempt order with last-wins, and a correction can only
+   change the defect judgement, never the outcome. There is NO
+   HTTP endpoint for marking or correcting defects in this
+   track -- the function is the interface, and an endpoint (with
+   the ``approve_merge`` permission check) is follow-up work,
+   listed as unconnected in the track summary. Until it exists,
+   defect marks come only from explicit, reviewed calls, never
+   from automation.
+
+7. Failure discipline. Every hook write is best-effort: a ledger
+   or marker failure is logged (``worker_attempt_ledger_failed``
+   / ``worker_attempt_marker_failed``) and NEVER fails the task,
+   blocks a requeue, or changes a task's status. The one
+   exception is validation inside ``record_attempt`` /
+   ``record_correction`` (bad outcome, defect on an interrupted
+   row, correcting a nonexistent attempt): those raise
+   ``ValueError`` BEFORE writing, by design, so ambiguous data
+   is never stored -- but the worker hook only ever passes
+   validated values (a terminal outcome, ``is_defect=False``),
+   so it cannot hit that path in normal operation.
+
+8. Postgres. The marker table follows the ledger table's manual
+   discipline: it is NOT created by ``init_postgres_schema``,
+   and ``PG_MARKER_DDL`` below is the exact statement to run by
+   hand on production Postgres (and verify) before enabling the
+   hook against a Postgres-backed control plane. Until that
+   step runs, marker writes fail (best-effort, rule 7) and
+   platform dispatches degrade to counted -- the same
+   fail-safe direction as rule 5's mid-flight edge, and the
+   reason the PG manual step is a precondition for enabling
+   the hook in production, not an afterthought. Real Postgres
+   verification was NOT done on this track (no local Postgres):
+   PG evidence here is adapter-level only (``?`` placeholders
+   translate to ``%s`` through ``cloud.db``, DDL uses only
+   Postgres-valid types, no autoincrement/identity column),
+   exactly like gap 3's PG evidence, and labelled as such.
+   Integration v2 out-of-box closure (see
+   ``cloud/ledger_onboarding.py``): the DDL checklist, the
+   explicit enable path and the read-only
+   ``verify_ledger_ready`` / ``ledger_setup_report`` probe
+   close the "hook off by default + manual PG DDL" gap
+   WITHOUT changing the default (still OFF) or auto-running
+   DDL on production Postgres -- the manual PG step remains
+   an operator action, now checkable instead of assumed.
+
+This module imports ``cloud.attempt_ledger`` only, opens no
+database connection itself (callers pass a connection in), and
+contains no ``sqlite3.connect`` / ``psycopg*`` import, so the
+``arch_conformance`` layer rules are untouched.

+"""Task-attempt ledger for the step-5 metrics loop (audit gap 3).
+
+Choice made here, with the trade-off stated rather than hidden:
+
+- This module adds a SEPARATE ``task_attempts`` table; it does NOT
+  add ``attempts``/``defects`` columns to ``tasks``. Columns would be
+  simpler to query (one row per task, no join), but they collapse
+  history into two counters: a task's per-attempt story (which
+  attempt failed, with what defect category, in what order) would be
+  unrecoverable, and widening the hot ``tasks`` table on production
+  Postgres is a heavier migration than adding a new, empty table.
+  The ledger costs one aggregate query at report time, and that
+  query is exactly what ``aggregate_attempts`` exists to pin down.
+- The ledger is append-only in intent: ``record_attempt`` only ever
+  inserts a new ``(task_id, attempt_no)`` row (``attempt_no`` is
+  ``MAX + 1`` per task, never reused). There is no update path, so a
+  recorded attempt cannot be silently rewritten into a first-pass
+  success after the fact.
+
+Semantics (pinned by tests, not left to each caller):
+
+- One row = one real attempt at the task. ``outcome`` is one of
+  ``success`` / ``failure`` / ``interrupted``.
+- ``interrupted`` rows are kept for audit but NEVER count toward
+  ``attempts`` or ``defects``: a platform interruption that
+  auto-resumes as a fresh run is a platform event, not an agent
+  failure, and the step-5 rule that ``interrupted`` is not a
+  terminal task status would be meaningless if the interruption
+  still inflated the attempt count. A task whose ledger holds only
+  interrupted rows has NO counted attempt, so it is omitted from
+  the aggregate entirely -- the endpoint then still reports its
+  rates as unknown (``None``), never as 0.
+- ``is_defect`` is set explicitly by the recorder, never inferred
+  from ``outcome``: a failed attempt is not automatically a defect
+  (a retry can fail for a transient reason without being a
+  defect round), and a defect round is a judgement the recording
+  caller makes. ``defect_category`` requires ``is_defect``; an
+  interrupted row can never be a defect. Both contradictions raise
+  ``ValueError`` instead of being stored as ambiguous data.
+- ``defect_category`` for a task (the single category that
+  ``compute_metrics`` carries per task) is the category of its
+  FIRST defect row in attempt order. Later defect rows still count
+  toward ``defects``; only the category label is first-wins, so it
+  is deterministic. Corrections (below) re-evaluate this label:
+  the first defect row AFTER corrections is applied wins.
+- A defect judgement can be CORRECTED, never rewritten:
+  ``record_correction`` appends a new row whose
+  ``corrects_attempt_no`` points at the attempt it corrects; the
+  old row stays untouched, and aggregation applies corrections in
+  attempt order with last-wins (so a wrongly marked defect can be
+  unmarked, and a defect missed at record time can be added after
+  review). A correction row is never itself counted as an
+  attempt, cannot change an attempt's outcome (only its defect
+  judgement), and cannot target an interrupted row, another
+  correction row, or a nonexistent attempt -- all raise
+  ``ValueError`` and write nothing. Who may correct is a policy
+  question answered in ``cloud/attempt_hook.py`` (explicit
+  recorder only, maintainer bar); the worker hook never writes
+  corrections and never marks a defect.
+- Old tasks have no ledger rows, and that is NOT backfilled: the
+  aggregate simply has no entry for them, the endpoint leaves their
+  ``attempts``/``defects`` as ``None``, and ``compute_metrics``
+  excludes them from rate denominators (they are neither counted
+  as first-pass nor as defect-free). Fabricating a row for an old
+  task (e.g. ``attempts=1, defects=0`` from "it completed") would
+  be inventing history.
+
+Persistence notes:
+
+- One table, one definition. ``task_attempts`` is defined ONCE
+  below (``TASK_ATTEMPTS_DDL``, aliased as ``SQLITE_DDL`` /
+  ``PG_DDL``); ``cloud.attempts`` (the resume-history writer) and
+  ``cloud.db.POSTGRES_SCHEMA`` (the fresh-Postgres schema) both
+  import this same string instead of carrying their own copy.
+  The two historical shapes -- main's resume DDL (``kind`` /
+  ``interrupted_reason`` / ``checkpoint_round`` / ``result_text``
+  / ``error_text``) and gap 3's ledger DDL (``outcome`` /
+  ``is_defect`` / ``defect_category`` / ``corrects_attempt_no``)
+  -- are superseded by this unified definition, which carries
+  both column groups. The shared columns (``task_id``,
+  ``attempt_no``, ``created_at``) had identical meaning and type
+  on both sides, so there is no semantic conflict to arbitrate:
+  the union of the column sets IS the unified schema, with one
+  deliberate relaxation (see below).
+- Row kinds in one table. A row is a ledger row iff ``outcome``
+  is non-NULL (written by this module, outcome validated in
+  Python before the insert); a row with ``outcome`` NULL is a
+  resume-history row (written by ``cloud.attempts``). The two
+  writers insert disjoint column groups and read by column name,
+  so they share the table without overwriting each other's
+  fields. ``aggregate_attempts`` counts ONLY ledger rows: a
+  resume row (outcome NULL) is skipped, never counted as a
+  defect-free first pass -- otherwise a task that was merely
+  auto-resumed would silently gain a counted attempt.
+- The one deliberate relaxation: ``outcome`` is nullable in the
+  unified DDL even though the ledger writer always supplies it.
+  A ``NOT NULL`` on ``outcome`` would make the resume writer's
+  insert (which has no outcome to report) fail on a fresh table,
+  so the constraint lives in Python validation here, not in the
+  DDL. ``is_defect`` keeps ``NOT NULL DEFAULT 0`` so a resume
+  row that omits it still reads as "not a defect judgement".
+- SQLite: ``ensure_task_attempts_table`` runs
+  ``CREATE TABLE IF NOT EXISTS`` with the unified DDL, then
+  migrates a pre-existing legacy table (old resume shape, gap-3
+  ledger shape, or the rehearsal-era 12-column shape) by adding
+  whichever unified columns it lacks. Added columns are always
+  nullable or defaulted, so existing rows are never blocked;
+  SQLite ``ALTER TABLE`` cannot tighten an existing column's
+  nullability, so a migrated table keeps its looser column
+  types -- the column SET and the data are unified, the
+  ``NOT NULL`` spelling on fresh tables is not retrofitted.
+  This is a migration to the single canonical definition, not a
+  second definition assembled at runtime.
+- Postgres: the production table is NOT created by
+  ``init_postgres_schema`` (deliberately: that schema is covered by
+  the migrations test asserting ``MIGRATION_TABLES`` equals the
+  schema set, and this ledger must not silently widen that set).
+  ``PG_DDL`` below is the exact statement to run manually on
+  production Postgres and verify (``\\d task_attempts`` or the
+  ``information_schema`` equivalent) before any Postgres-backed
+  endpoint is expected to return real rates. The DDL uses only
+  Postgres-valid types (``TEXT``/``INTEGER``/``DOUBLE PRECISION``),
+  a composite primary key, and no ``AUTOINCREMENT``/identity
+  column, so it needs no sequence handling; the parameterized
+  ``INSERT`` uses ``?`` placeholders, which the ``cloud.db``
+  Postgres adapter translates to ``%s`` (see the adapter test in
+  ``test_attempt_ledger.py``). Until that manual step runs, the
+  endpoint treats a missing table exactly like "no ledger rows":
+  unknown rates, not an error -- the same fail-soft shape already
+  used for missing ``cost_records``. The Postgres upgrade path
+  for a legacy-shaped table was verified against a real
+  Postgres 16.15 instance on 2026-11-06 (fresh ``PG_DDL``,
+  three legacy shapes migrated in place, both writers, PK,
+  idempotent ensure; see
+  ``verification/codex-task-attempts-pg-proof-20261106.md``).
+  One gap-3-only step relaxes a gap-3 table's ``outcome``
+  from NOT NULL with ``ALTER COLUMN outcome DROP NOT NULL``
+  (see ``ensure_task_attempts_table``); the statement works
+  on Postgres and on SQLite 3.53.0+, and is swallowed by
+  ``try/except`` on older SQLite, where the column stays
+  NOT NULL.
+- The read path (``GET /metrics-report``) never creates the table:
+  a read-only endpoint must not mutate schema. Table creation
+  happens only on the write path, inside ``record_attempt`` /
+  ``record_correction``.
+- Lifecycle hook (this track, see ``cloud/attempt_hook.py``):
+  the worker writes exactly one row per COUNTED dispatch (see
+  that module's policy for which dispatches count: human/first
+  rounds and human breakpoint resumes count; platform auto-resume
+  reruns, coordinator fan-out, and pre-execution gate failures do
+  not). The hook is OFF by default (``attempt_ledger_hook=False``):
+  with it off, this module's behaviour is exactly audit gap 3 --
+  the ledger fills only through explicit ``record_attempt`` /
+  ``record_correction`` calls, and production rates stay honestly
+  unknown until the hook is deliberately enabled. The worker hook
+  always records ``is_defect=False``: it never judges a defect,
+  so enabling it can never turn a transient retry into a defect.
+- Schema evolution note (unified schema, this batch):
+  the old resume DDL, the gap-3 ledger DDL, and the rehearsal
+  12-column shape are all legacy shapes of the SAME table.
+  ``ensure_task_attempts_table`` migrates any of them to the
+  unified column set in place (add missing columns only, never
+  drop or rewrite rows); the read path uses ``SELECT *``
+  deliberately so rows of any shape still read, and
+  ``aggregate_attempts`` treats a row without an outcome as a
+  resume row, not as a ledger attempt (see above).
+
+This module imports no ``cloud.*`` module and opens no database
+connection itself: callers pass a connection in, so the layer rules
+(``arch_conformance``: no direct driver connection outside
+``cloud.db``) are untouched -- there is no ``sqlite3.connect`` and
+no ``psycopg*`` import here at all.

+
+已有的、不在本轨重复造的机制（查代码确认）：
+- 任务创建幂等：tasks 的 UNIQUE(project_id, idempotency_key)，
+  重复创建回读已有任务，并发抢建靠 IntegrityError 回读。
+- goal 断点：task_checkpoints 每轮快照（worker 镜像线程 +
+  终局导入），goal 任务自动续跑走同一线程、同一 worktree、
+  从 goal_rounds_done 下一轮起；无进展熔断（断点轮次 3 次
+  不变即 stall）与退避、次数上限并存。
+- 合并与通知的 CAS：终局写回只在 running 时成功才写结果、
+  记成本、发通知，重复终局不重复记账发通知；协调员子任
+  务按分工名复用，不重复建。
+
+本轨补的缺口，恰恰是上述机制都没盖住的那一段：非 goal
+任务被平台中断后，auto_resume_interrupted 会把它全新重
+排——同一 worktree 里文件还在，但重排前会清掉 result_text /
+error_text / interrupted_reason，新一轮 agent 只拿到原始
+prompt，既不知道上一尝试做到哪一步、出了什么错，也无法
+区分“worktree 里已有的文件是上一尝试的产物还是仓库原有
+内容”，于是可能重复创建上一尝试已创建的东西。goal 任务
+不受此影响（线程连续性自带历史），协调员子任务也不受此
+影响（auto_resume 本来就不接 coordinator_orphan）。
+
+本轨只做三件可执行的事，全部在 worker/server 层，不改
+host.py、不改 codex 线程恢复：
+① 尝试账本 task_attempts：auto_resume 把任务回 queued
+  之前，先把正结束的这次尝试记下来——attempt_no（= 旧
+  auto_resume_count + 1，即正结束尝试的序号）、kind
+  （goal_breakpoint 或 platform_fresh）、interrupted_reason、
+  checkpoint_round（库中断点最大轮次，非 goal 恒为 -1）、
+  result_text / error_text 各截断 2000 字。记账与回 queued
+  在同一事务里，记账失败不单独炸恢复循环（外层已兜底），
+  但同一 (task_id, attempt_no) 重复记时 INSERT OR IGNORE
+  保留第一次，不覆盖。表定义是统一 schema（FLAG-1，
+  2026-11-05）：本模块不自带一份 DDL，CREATE_TABLE_SQL
+  与建表/迁移均取自 ``cloud.attempt_ledger`` 的
+  ``TASK_ATTEMPTS_DDL`` / ``ensure_task_attempts_table``，
+  与台账写路径共用同一定义；本模块写的行 outcome 为
+  NULL（恢复历史行，非台账计数行，见 attempt_ledger 对
+  aggregate 的口径）。
+② 重跑前言：非 goal 平台全新重排的任务在认领时，worker
+  在内存副本的 prompt 前贴一段上次尝试说明（原 prompt
+  不落库，与项目/待办/记忆注入同款只改内存副本），内容
+  是账本里的事实——第几次尝试、中断原因、断点轮次、上一
+  尝试部分输出与错误（各截断 1000 字）——并明确要求先查
+  worktree 现状再动手、对 worktree 外的产物先核查再创建。
+  goal 断点续跑、_resume 任务、协调员任务一律跳过（它们
+  已有会话连续性或不跑模型回合）；账本里查不到记录的老
+  任务原样返回，不编造。
+③ 时间线读回：GET /tasks/{id}/timeline 在 steps /
+  checkpoints 之外加 attempts 数组，项目 read 权限复用
+  时间线原有校验，只读不改。
+
+诚实边界（写进模块与交付，不宣称）：
+- 前言是指令不是保证：agent 仍可能重复创建，账本只能
+  降低重复概率，不能像创建幂等键、合并 CAS 那样硬保证
+  不重复。worktree 外的产物（分支、PR、发布等）账本不
+  追踪——它只记 DB 里已有的事实，不读 worktree、不调外
+  部 API；那些产物的硬去重仍靠各自已有的门（创建幂等键、
+  合并状态 CAS、分工名复用）。
+- 本轨不做 worktree 文件快照：快照路径因执行器而异
+  （local / Docker 租户 / cloud 的 worktree 位置不同），
+  在 worker 层硬做快照会把执行器差异漏进账本；agent 在
+  本轮里自己查 worktree 现状是更可靠的口径。
+- 手动重试（/retry、/continue 等）不经过 auto_resume，
+  故不记尝试账本、不贴前言——用户显式重试时由用户自己
+  在新消息里给上下文，本轨不替用户编造上一尝试说明。

+"""有界自动审计循环（audit loop），只对确定性门做自动循环。
+
+设计前提（先核实再动手，见模块末尾的“复用清单”）：
+生产代码里没有“审计员 agent”，所以这里的“审”只能是确定性
+检查的结果——测试/校验命令、能力门、干跑阻塞、迁移列、格式
+等可客观判定对错的门。主观审计（架构、设计、代码美观）绝不
+触发自动循环，只返回 needs_review，走人工。
+
+有界方案（用户已定，一字不差地落地）：
+1. 只对确定性门循环：Finding.kind 只能是 deterministic 或
+   subjective；subjective 一律 needs_review，不推回、不计轮。
+2. 推回包写死：每条 Finding 必须带 id、evidence、reproduction、
+   acceptance，四者缺一即 ValueError（调用方 bug，不进循环）；
+   PushbackPacket 带 round、findings、criteria（本轮结束后仍未
+   解决的验收标准，finding_id -> gate_or_None）。
+3. 上限 3 轮：round = 已发出的推回数；round < 3 且有 finding 才
+   推回，round >= 3 且仍有 finding 即升级（escalate），不再循环。
+4. 重审审全量：每轮必须重跑全部门；上一轮通过的门本轮未跑
+   即 gate_missing 升级；上一轮通过的门本轮变失败即 regression
+   finding，同样不得放行。
+5. 标准不得弱化：上一轮的 finding 只有在三种情况下才算解决——
+   本轮仍被报告（仍在解决中）、调用方以 fixed 传入已修复证据、
+   其关联 gate 本轮通过；否则该 finding 被丢掉即 standards_weakened
+   升级，绝不默许把标准越放越宽。
+6. 默认关闭：引擎只由 Worker.audit_loop_evaluate 显式调用，且仅当
+   任务字典含 audit_loop 真值时才启用；没有 env 开关——全局 env
+   会让所有任务悄悄启用循环，这是本设计刻意拒绝的。开关关闭时
+   run_one、auto_resume、协调员、goal 断点行为逐字节不变（本模块
+   不改 run_one，见 Worker 方法的文档）。
+7. 轮次持久化：状态存在 task_audit_loop_state 单行表（task_id 主键），
+   跨 worker 重启不丢；计数缺失或损坏时 fail-closed 到升级，绝不
+   默认循环。审计行（audit_log）是 best-effort，写失败会丢计数，
+   所以轮次绝不以审计行计数为准——这是不用审计行做持久化的原因。
+
+复用清单（核实结论）：
+- goal 的 verify_command：goal 任务已有的确定性校验门，本引擎
+  不重复造校验，只消费“门的结果”（gate_results）。
+- task_attempts 尝试账本：本引擎不复用它做轮次持久化，原因
+  是它的主键是 (task_id, attempt_no)，与 goal/platform 尝试共用
+  attempt_no 序号——audit_loop 若也用 attempt_no 记轮次，序号会
+  与已有尝试撞主键、被 INSERT OR IGNORE 静默丢掉，轮次就丢了。
+  因此按 attempts 的 DDL 手法（模块内 CREATE_TABLE_SQL +
+  ensure + db.py POSTGRES_SCHEMA + migrations 表清单 + server
+  初始化调用）另起单行表，序号冲突问题不存在。
+- task_followups：特意不复用——它是用户消息（用户含任务间互发），
+  把机器推回包写进 followups 会把机器包暴露给用户、混淆用户消息。
+  推回包由调用方持有（返回的 packet dict），不落 followups。
+- 协调员重排（UPDATE tasks SET status='queued' 带状态 CAS）：
+  调用方若要重排，用同一手法；本引擎本身不改任务状态、不重排、
+  不调 runner——状态变更属于调用方，引擎只给决策。
+- worker 的 fail-fast 门（能力门、工具门等）：本引擎不替代它们，
+  只在它们已经判定出的结果之上做“循环还是升级”的决策。

+"""Audit-of-audit sampling: human review of audit verdicts.
+
+Zero third-party dependencies; standard library only, no ``cloud.*``
+imports. All functions are pure: they return plans, verdicts and
+records, never auto-apply a correction -- applying a correction is a
+separate, recorded step (see ``handle_sampling_result``).
+
+This module implements the sampling half of the "audit itself must
+be audited" rule. It does NOT change the audit verdicts, the
+pushback/rebuild counters, or the golden-set approval flow; it only
+defines which audit cases a human must re-examine, and what happens
+when that re-examination finds the audit wrong.
+
+UNIFIED SAMPLING RULE (single rule; this module is canonical for
+selection, ``cloud/audit_pushback.py::select_audit_sample`` is only
+its record-shaped adapter -- there is no second rule):
+
+The scope of "mandatory" comes from track 3 (#244): golden-task
+records and rebuild / refreeze / escalation records. The drawing
+mechanism comes from track 5 (#238): seeded random draws with ceil
+rounding. Track 3's old deterministic "every 10th record" rule is
+superseded and removed: a batch of fewer than 10 ordinary records
+drew zero under it, and a position-known draw is predictable. The
+rates below are TEST DEFAULTS (``DEFAULT_*``), not approved
+production values; the production rates are still a user decision.
+Mandatory 1.0 is a rule, not a tunable rate.
+
+Sampling rules (all testable, none left to "regular review"):
+
+1. Mandatory sampling (ratio 1.0, never skipped). A case is
+   mandatory when ANY of these triggers holds (trigger order for
+   display and for the legacy single-trigger helper is golden,
+   rebuild, third-failure, refreeze, escalate):
+   - ``golden_task``: the case's task is in the human-approved
+     golden set (``task_id`` when present, else ``id``). A golden
+     task's records are mandatory whatever their kind -- an
+     ordinary pass verdict on a golden task is sampled, not just
+     its failures.
+   - ``rebuild``: any case whose audit decision was rebuild-from-
+     scratch (推倒重做). A rebuild destroys the old implementation
+     in the workspace, so its verdict must always be re-examined.
+   - ``third_failure_near_complete_still_failed``: a case whose
+     third failure was root-caused as near-complete (接近完成),
+     was given one targeted continuation round, and still failed.
+     This is the exact boundary where the "one more round vs
+     rebuild" judgement is most error-prone, so it is always sampled.
+   - ``refreeze``: a contract/design re-freeze record.
+   - ``escalate``: an escalation record.
+   A near-complete third failure whose continuation round SUCCEEDED
+   is not mandatory (the judgement proved itself), and a
+   near-complete first/second failure is not mandatory either (the
+   threshold is the third failure, per the rebuild rule). A
+   ``blocked_quota`` record is NOT mandatory under this rule (it
+   is not in track 3's mandatory kind list); it is sampled only
+   through the random tiers below.
+
+2. Random sampling of the rest, with the seed recorded:
+   - normal audit cases: default ratio 0.10;
+   - critical-path cases (``critical_path=True`` and NOT already
+     mandatory): default ratio 0.50 -- critical paths get a higher
+     rate, not a free pass. (Track 3's old ``critical_path``
+     reason label for mandatory kinds is retired: mandatory kinds
+     now carry their own trigger names, and ``critical_path``
+     means only this 0.50 random tier.)
+   Mandatory cases are removed from the random pools BEFORE
+   drawing, so they consume no random quota. The seed is part of
+   the plan: a sample selected without a recorded seed is not
+   reproducible and therefore not auditable. Selection is
+   deterministic given (cases, ratios, seed).
+
+4. One pass, no double counting. Selection partitions every case
+   exactly once: mandatory (all its triggers listed, one sample,
+   one sampling entry) or random-critical or random-normal. A
+   record that is both a golden task AND a rebuild is sampled
+   ONCE, with ``triggers == ["golden_task", "rebuild"]``; its
+   correction, if any, is a single record whose retrigger follows
+   the (original, corrected) verdict pair, not the trigger list --
+   triggers decide selection only, never the correction action.
+   Two different records (e.g. a triage record and the later
+   rebuild record for the same task) are two samples, not a
+   double count: deduplication is per record, not per task.
+
+5. Golden-set construction. The caller-supplied golden id set
+   must be built from human-approved, non-sample tasks only:
+   ``build_golden_task_ids`` applies both vocabularies -- a task
+   counts only with ``human_approved_by`` set AND none of
+   ``is_example``, ``sample=True``, or an id starting with
+   ``sample-``. Track 3's per-task approver rule and track 5's
+   sample-exclusion rule are both preserved; neither alone is
+   sufficient.
+
+6. Correction gate effect (shared with track 3 / wiring #247).
+   A sampling correction NEVER unblocks a merge by itself: a
+   correction to ``pass`` (a wrong block) schedules a re-audit
+   and the gate stays blocked until a new passing re-audit
+   conclusion exists; a correction to ``fail`` (a wrong pass)
+   re-triggers pushback and re-blocks at once. Vocabulary
+   synonyms for the same pair actions: track 3
+   ``retrigger_pushback_and_reblock`` == track 5
+   ``reopen_audit_and_pushback`` (wrong pass), and track 3
+   ``schedule_reaudit`` == track 5
+   ``cancel_pushback_and_rerun_audit`` (wrong block, where
+   "cancel" means cancel-and-rerun, never cancel-and-merge).
+
+3. Golden-set approval is separate from sampling and is NOT
+   satisfied by sample files: ``filter_golden_tasks`` drops any task
+   flagged as a sample (``sample=True`` or an id starting with
+   ``sample-``) and reports how many were dropped; a golden set
+   counts only its remaining, human-approved tasks. The approval
+   checklist (``golden_approval_checklist``) lists every item that
+   must be human-completed before a golden set is approved; until
+   then every item reads ``pending_human``.
+
+Handling a sampling result (``handle_sampling_result``):
+
+- Sampling says the audit was CORRECT: no correction, only a record
+  entry (the audit stands, with evidence it was re-examined).
+- Sampling says the audit was WRONG: the original conclusion is
+  corrected in the record, and the corresponding flow is
+  re-triggered:
+    - wrongly issued pushback -> ``cancel_pushback_and_rerun_audit``
+      (cancel the pushback, restore the pre-pushback state, rerun);
+    - wrongly issued rebuild -> ``halt_rebuild_and_restore``
+      (halt the rebuild, restore the original implementation from
+      git history/tag, rerun -- the old implementation is preserved
+      by the rebuild rule itself, so restoration is possible);
+    - wrongly issued pass (a failure the audit missed) ->
+      ``reopen_audit_and_pushback`` (reopen with the corrected
+      verdict and run the pushback flow the audit should have run);
+    - unknown original decision -> ``escalate_to_human`` (never
+      invent a retrigger).
+  Every outcome, correct or corrected, is appended to the
+  audit-of-audit record (``append_audit_record``); a sampling result
+  that is not recorded is treated as not having happened.

+"""Wiring between three already-landed tracks (no new semantics here):
+
+- track 1 (``cloud/merge_gate_hard.py``, PR #240): the hard merge
+  gate, five checks + branch protection, machine-readable ``blocks``
+  codes on its 409 response;
+- track 3 (``cloud/audit_pushback.py``, PR #244): the independent
+  audit + auto-pushback decision, the pushback package, and the QA
+  re-run rule;
+- track 4 (``cloud/ledger.py``, PR #241): the append-only hash-chain
+  ledger, the only durable store in this wiring.
+
+What this module owns, and nothing else:
+
+1.  Translation at the boundary. Track-3 field names and enums are
+    authoritative for callers; track-4 storage field names are
+    authoritative on the chain. This module translates, it does not
+    invent a second ledger schema:
+
+    ============================  ===================================
+    track-3 event                 chain record (track 4 action)
+    ============================  ===================================
+    audit verdict                 ``audit_verdict``
+    pushback round (pushed)       ``audit_pushback_round`` (pushed)
+    fix (landed, re-audit open)   ``audit_pushback_round`` with
+                                  ``fix_diff`` + package marker
+                                  ``wiring_event="fix"`` (evidence
+                                  row only; see the gate reader)
+    fix + re-audit                ``audit_pushback_round``
+                                  (re_reviewed, ``fix_diff`` +
+                                  ``re_review_result``)
+    rebuild decision / done       ``audit_rebuild``
+    third-failure triage          ``audit_third_failure_assessment``
+    test-change single audit      ``audit_test_change``
+    audit-of-audit correction     ``audit_meta_review``
+    rebuild notice / confirmation ``audit_rebuild_notice``
+    escalation / blocked quota /  ``audit_wiring_event`` (the one
+    audit sample                  compat action added to track 4
+                                  by this wiring; see below)
+    ============================  ===================================
+
+2.  CONDITIONAL mapping, done here and only here. Track 4 stores
+    verdicts as ``pass`` / ``fail`` only, and track 3 says
+    CONDITIONAL is not a pass. Every verdict (audit verdict and
+    re-audit verdict) that arrives as ``"conditional"`` -- or as
+    anything that is not exactly ``"pass"`` -- is stored as
+    ``"fail"``, with the original value preserved in
+    ``extra.original_verdict`` (verdict rows) or in
+    ``re_review_result.original_verdict`` (pushback rows). The
+    original conclusion is never overwritten: the chain keeps the
+    mapped value AND the original, and corrections are separate
+    ``audit_meta_review`` rows, never edits.
+
+3.  The gate reader (``pushback_block_for_task``). It replays a
+    task's chain rows in id order and returns a ``gate_block()``-
+    shaped dict (``merge_blocked`` / ``release_blocked`` /
+    ``blocked_by="audit_pushback"`` / ``round`` / ``failed_checks``,
+    plus a ``modules`` detail map). ``cloud/server.py`` ANDs this
+    with the hard gate's own five checks: either side blocks and
+    the merge returns 409 with the task status unchanged. The
+    pushback block applies in every gate mode -- an open audit
+    pushback is not something a ``record``-mode caller can confirm
+    away, and ``merge_gate_confirm`` never touches it.
+
+4.  The gate-blocks-to-package bridge
+    (``pushback_package_from_gate``). A hard-gate 409's ``blocks``
+    codes are machine input to the pushback package: each code maps
+    to a track-3 gate check (``ci_*`` -> ``ci_green``,
+    ``directory_*`` -> ``directory_isolation``,
+    ``contract_*`` -> ``contract_version``,
+    ``coordinator_*`` -> ``coordinator_approval``,
+    ``review_*`` / ``unresolved_review_comments`` ->
+    ``unresolved_review_comments``). Branch-protection codes have
+    no track-3 gate-check member, so they travel as the extra check
+    name ``"branch_protection"`` in the package's failed items --
+    they are never dropped, and they are never disguised as one of
+    the ten checks. Callers must take the codes from the 409
+    ``merge_gate`` object, never by parsing audit detail text.
+
+Known translation losses (stated, not hidden):
+
+- Track 3 distinguishes root causes ``"contract"`` vs ``"design"``;
+  track 4 stores only ``"implementation"`` / ``"contract_design"``.
+  Both contract and design map to ``"contract_design"`` on rebuild
+  rows (track 3's rebuild branch treats them identically: refreeze,
+  no code rebuild). The finer distinction survives on escalation
+  rows, which carry the original ``root_cause`` verbatim.
+- Track 3's third-failure triage verdict ``"early_refreeze"`` has
+  no track-4 assessment determination (only ``early_rebuild`` /
+  ``continuation_round`` exist there). It is recorded as an
+  ``audit_wiring_event`` of kind ``escalate_refreeze``, never
+  forced into an assessment row with the wrong determination.
+- Track 3's ``"unknown"`` root cause has no track-4 value and is
+  refused (``ValueError``) rather than guessed: a rebuild row must
+  say which side the root cause is on.
+- A fix-only row is counted by track 4's timeline summary inside
+  ``pushback_rounds`` (that summary counts rows, and a round
+  already spans two rows there). The gate reader skips fix rows
+  for state transitions, so the count wart cannot unblock or block
+  a merge by itself.
+
+What this module does NOT do:
+
+- It does not change any track-1 / track-3 / track-4 semantic:
+  hard stays fail-closed by default, protection unknown /
+  unprotected still block in hard mode, confirmation still never
+  covers a directory violation, the chain stays fail-closed and
+  append-only, and the cost dual-column rule is untouched.
+- It does not create pushback subtasks, send notices, or run
+  fixes. ``record_*`` only appends chain rows; deriving a fix
+  subtask from a package is the caller's job (track 3's
+  ``build_pushback_package`` already describes its shape).
+- It does not gate ``deploy.py``. There is no server-side release
+  endpoint in this codebase: the merge endpoint is where
+  ``merge_blocked`` is enforced, and ``release_blocked`` is
+  returned alongside it so a future release endpoint can enforce
+  it with this same reader. Deploy remains an operator action
+  outside this wiring.

+- 有界委派（v5，Foundry“有界 subagent 委派”的对应物）：
+  每个分工除 name/prompt/model/effort/executor 外，还可带
+  三个显式边界，全部在 validate_parts 校验、经 DB 的
+  coordinator_parts JSON 原样流转、由 worker 的协调员循环
+  真正执行，不是只写进 prompt 的愿望：
+  ① timeout_seconds：该分工单次委派的墙钟上限，从协调员
+  本轮开始计时，超时由协调员循环直接 cancel 该子任务
+  （与全局超时同款 cancel 机制），其他分工继续等，不因
+  一个慢分工拖住整批到全局超时；② on_failure：fail（默认，
+  旧行为，任一非容忍分工未完成则协调员失败）或 tolerate
+  （该分工失败不拖垮协调员，汇总里点名已容忍，协调员
+  重跑时其 failed 子任务不再重排、interrupted 的仍重排，
+  因为后者可能是父任务取消所致、未获公平一轮）；③
+  result_chars：回传给父任务的单项输出上限，默认 500，
+  汇总报告本身仍受 worker 写回的 4000 字上限约束。
+  三个边界的执行点都在协调员层：超时在循环里 cancel，
+  容忍在合流评价里算，截断在汇总报告里切。
+
+- v5 明确不宣称的边界（查代码后的诚实口径，勿以字段
+  冒充执行）：① 每分工 token/费用预算：成本记录只在任务
+  完成时写，运行中的子任务花费在循环里观测不到，创建人
+  配额是按月不是按分工，所以不存在可执行的分工费用门，
+  v5 不加 max_tokens/max_cost 字段；② 每分工轮数上限：
+  普通任务在 worker 侧没有按任务的轮数上限（只有 goal
+  任务的 goal_max_rounds 与 worker 进程级的 max_turns），
+  所以 max_rounds 字段在子任务执行层无法执行，v5 不加；
+  ③ 写范围隔离：沙箱按项目 worktree 隔离、不按分工
+  量子目录隔离，prompt 里写“只写 docs/”是指令不是保证，
+  所以 v5 不加 scope 字段冒充隔离。这三项要做需先改
+  执行层（成本流、轮数帽、沙箱子目录），不在本轨范围。
+
 本模块只放纯逻辑（校验、解析、汇总、建表），不碰 DB 之外的
 任何东西，单测不需要 worker/server。

+"""评估闭环 v7：金任务 + 确定性评分 + 两轮对比报告。
+
+为什么需要这一轨（查代码确认的缺口）：
+- 路由影子评估（cloud/routing_shadow.py）只给成本与状态，
+  给不了质量；它自己也承认反事实 not_measured——影子建议
+  模型从未跑过，无法比较建议与实际的成本质量。
+- 生产代码里没有金任务、评分器、rubric：harness2.py 明确
+  写着“没有评分器、没有 rubric；delivered 的定义由 adapter
+  说了算”。所以“建议模型是不是真的更好”此前没有任何
+  机制能回答，只能凭感觉或凭成本。
+- Foundry 的评测思路是同任务跑不同 harness/模型比通过率，
+  本轨把这个思路落成可执行的最小闭环，但刻意不做成
+  “自动判优”：报告只给数据与人工评审结论，不激活任何
+  路由、不改任何策略。
+
+本轨是什么（纯模块 + CLI，不碰 DB、不跑模型）：
+- 金任务：一组 JSON 定义，每项 {id, prompt, tier, checks}。
+  checks 只认四种确定性检查：contains（结果含某串）、
+  not_contains（结果不含某串）、status_completed（任务
+  状态为 completed）、max_tokens、max_cost_usd。校验失败
+  （重复 id、未知检查类型、空 checks、空 prompt、非法
+  tier）即报错，绝不静默跳过一条检查。
+- 评分：对已完成任务的记录打分，不执行任务。输入记录为
+  {task_id, golden_id, model, status, result_text,
+  total_tokens, usd_micros, unpriced_tokens}，其中 usd_micros
+  与 cloud/cost.py 同款微美元单位。单项得分 = 通过检查数 /
+  已测定检查数；未测定检查（成本数据缺失时的 max_tokens /
+  max_cost_usd）不计入分母、单独列出，绝不把“没数据”
+  当成通过或失败；result_text 为空时字符串检查按空串算，
+  是失败不是未测定（输出已知为空）。
+- 对比：两轮（例如模型 A vs 模型 B，或同一模型改 harness
+  前后）在同一金任务集上的报告。分三层：每轮总体（任务
+  数、通过率、平均分、平均 token、平均 USD（仅已定价）、
+  未定价任务数）、配对差值（只算两轮都有的金任务，未配
+  对的任务不进差值、单独列出）、逐金任务对照表（每项在
+  两轮里是 pass/fail/unknown/missing）。配对样本 < 20
+  时（与影子评估 MIN_SAMPLES 同阈）报告 ready_for_decision
+  为 false 并写明“样本不足，不能据此做激活决定”；报告
+  不算显著性、不给 p 值——小样本下算显著性是编造精度。
+
+本轨明确不做、不宣称的事：
+- 不跑任务：本轨不创建生产任务、不调模型、不花模型费。
+  金任务要跑起来，需另起一轨（跑任务 + 回填记录），或
+  人工按金任务 prompt 建任务、把已完成记录导成 JSON 再
+  评分。本轨的 CLI 只读两个 JSON 文件，绝不联网、不写库。
+- 不用 LLM 当裁判：没有“质量分”“文笔分”“相关性分”。
+  需要人工判断质量的任务，确定性检查测不出来——那种
+  任务不应硬塞进金任务集，而应走人工评审；把字符串包含
+  当成质量证明是错的。
+- 防作弊警告：contains 检查可被“原样回显 prompt”骗过，
+  所以金任务的检查应尽量要求算出结果（例如一个具体数值、
+  一段必须经计算才得到的输出），而不是只要求出现关键词；
+  模块无法检测作弊，金任务集本身必须由人 curated，检查
+  写得越像“必须做对才过”，报告才越可信。
+- 不连路由：报告里不出现“建议激活某模型/某档”；激活
+  仍走人工评审 + 策略文件 + 干跑校验那条路，本轨只是给
+  评审多一份质量证据，与影子报告的成本证据并列。

+"""发布证据的新鲜度与单次使用绑定（集成 v2，代码层）。
+
+首轮缺口（全自动 9.5 扣 0.5）：发布门“重算”保证的是“不用
+旧结论”，不是“证据一定新鲜”——证据体里没有时间戳/nonce
+绑定，调用方把合并时同一份证据体在发布时原样重交，同样
+能通过重算。本模块补这一层，但诚实边界先写清：
+
+- 本绑定防的是**原样重放**（同一 nonce 二次提交）与**陈旧
+  证据**（时间戳超出窗口），不防**重盖戳**：没有签名的证据
+  体，调用方完全可以给旧内容盖一个新时间戳/新 nonce 再交，
+  本模块无法识破。防篡改/防重盖戳需要签名证据或第 5 项的
+  只读求证（向 GitHub 实时核对），那是另一层控制，不在本
+  模块冒充。
+- 绑定是**调用方自愿出示**的：请求体里同时带 evidence_ts
+  与 evidence_nonce 才进入绑定校验；两者都不带时走旧路径
+  （与 #259 契约兼容，响应里标注 evidence_binding=absent，
+  绝不谎称已验证新鲜）。只带其一是格式错误（400），不是
+  “半绑定通过”。把绑定改成强制，是契约决定，须协调员/
+  用户在合轨时定，不在本轨悄悄改 #259。
+- 单次使用语义：nonce 在**首次通过校验的提交**即被消费，
+  无论该次发布最终是 200 还是被其它门（未 merged、推回
+  阻塞）挡下——被挡的调用方下次必须取新证据重盖戳。这
+  是故意的：每次发布尝试都要求当次新鲜证据，而不是“一份
+  证据可反复试到放行”。
+- nonce 存储与审计链无关：evidence_nonces 表只记 nonce、
+  任务 id 与时间戳，不写 audit_log、不移动 #241 链头；409
+  不写审计的规则不受影响。表在写路径（首次消费）才建，
+  读路径（校验已存在）不建表——查不到表时视为无消费记

+"""全自动编程系统：一次授权后的主机自动执行器（API 优先）。
+
+本模块是“协调员只评审、人/宿主执行合并”缺口的闭合点，但
+执行人不是任务 agent：任务 agent 仍然不直接执行合并/部署，
+真正执行的是宿主侧的本模块（由已验证的 GitHub App
+installation + 显式开启标志门控），任务 agent 只交分支、
+自测证据和合并决定。两者混淆就是冒充，必须分清。
+
+设计约束（全部是硬规则，不是建议）：
+  1. 默认关闭：FULL_AUTO_ENABLED 未显式开启，或 installation
+     未验证，执行器一律拒绝，不存在“默认自动合”的状态。
+  2. 禁止清单 fail-closed：删库、force-push（含主分支）、改仓库
+     可见性、读密钥、外泄密钥、删分支保护、绕分支保护，未知
+     动作一律拒绝，不靠调用方自觉。
+  3. token 只进子进程/HTTP 请求头，不进审计记录、不进日志、
+     不进命令行、不进文件。本模块的审计记录在写入前会把
+     含 token/secret/password/key 的键和 Bearer 字符串抹掉；
+     调用方若把 token 塞进 detail，同样会被抹掉（宁可丢
+     字段，不可漏 token）。
+  4. 主分支保护强制开：自动配置的分支保护必须同时含要求 PR、
+     要求状态检查（strict）、禁止 force-push、禁止删除、
+     管理员同样受约束（enforce_admins），缺一项就不算配好。
+  5. 质量门禁阻塞合并：CI 全绿 + 目录隔离检查 + 契约版本 +
+     协调员批准，四项缺一就不合并。门禁不过时走 CI 自动修复
+     循环，限次（默认 3 次），超次升级给用户，不无限重试。
+  6. 回滚不靠 force-push：回滚只能是 revert PR 或重新部署
+     上一个 tag，绝不 force-push 主分支。
+  7. 建仓分支要诚实：GitHub App installation token 能建的是
+     组织仓库（POST /orgs/{org}/repos，需 administration 写
+     权限）；用户个人账号仓库的 POST /user/repos 需要用户
+     token，installation token 做不了。所以自动配置计划里，
+     “仓库不存在 + 无 org”时返回 needs_user_once 步骤：用户
+     在同一次安装会话里先建一个空仓（这是安装会话的一部分，
+     不是此后每轮的人工步骤），App 以 All repositories 安装
+     后即覆盖它。此后建分支、PR、CI、合并、发版全部走 API，
+     不再需要人工。把这一步说成“App 已自动建仓”就是冒充，
+     必须如实记为 needs_user_once。
+  8. 绝不做网页自动化自动注册 GitHub 账号：服务条款禁止
+     自动化创建账号，注册有验证码、邮箱验证、可能的人机/
+     手机验证，绕验证码会触发封号。本模块不提供、不调用
+     任何账号注册自动化，浏览器自动化只留作 API 覆盖不到
+     的配置页面兜底，不用来注册、不用来绕验证码。
+  9. 授权分层：控制台 OAuth 只证明本站身份，不带来 GitHub
+     权限；GitHub 权限靠 GitHub App 安装，仓库范围靠安装时
+     选 All repositories 一次覆盖现有与未来仓库，能力范围受
+     App 声明的权限封顶，新增权限必须改 App 声明并由安装方
+     在 GitHub 重新接受，无法静默升级。本模块不假装权限
+     可以自动升级：installation 的 permissions 由调用方
+     传入并核对，缺权限的动作直接拒绝并记为
+     needs_reaccept（需安装方重新接受），不静默降级执行。
+
+零第三方依赖，只用 Python 标准库。网络一律经调用方注入
+的 request_fn（约定与 cloud/github_app._github_api_request
+的 http_client 相同：(method, url, headers, body) ->
+(status, dict)），本模块自身不发真实网络请求，单测用假

+"""合并/发布门禁证据的只读核对器（集成 v2，代码层）。
+
+首轮缺口（门禁与审计 9.0 扣 0.5）：硬门禁与发布门禁强制
+的是“调用方提交的证据齐全且全绿”，不是“服务端已向
+GitHub 求证”——调用方谎报 CI 全绿 / 保护状态 / 协调员
+批准时，门禁会放行；docstring 称覆盖控制是“审计与
+PR/Checks 的只读核对”，但在合并/发布路径上没有这样
+一段“调 GitHub Checks API 核对证据”的代码（#210 的
+实时保护检查只属于 auto-config execute 端点，不属于
+merge/release 端点）。
+
+本轨的结论分两半，缺一不可：
+
+A. 核对器本身已实现（本模块，纯函数 + 注入式 reader，
+   有测试）：verify_gate_evidence(evidence, reader) 把
+   调用方证据与 reader 给出的实时数据逐项比对——CI
+   状态、每项 required 检查的状态、分支保护状态；不
+   一致即 mismatch（逐条列出），一致即 verified。reader
+   是调用方注入的 callable：reader(repo, ref) -> {
+   "ci_checks": {name: status}, "branch_protection":
+   "protected"|"unprotected"|... }，真实 reader 用
+   github_app 的 _github_api_request 走 GET Checks /
+   GET 分支保护（只读，绝不写 PR、不改保护、不合并）。
+   reader 为 None 或抛异常时结果是“未核对”
+   （checked=False, verified=False），绝不是“通过”——
+   调用方把 skipped 当 pass 用，是调用方的 bug，本
+   模块的返回值结构让这种误用一眼可见（verified 恒
+   False，除非逐项比对全过）。
+
+B. 实时求证在当前合并/发布路径上**接不上**（不可实现
+   证明，不是未做）：① 请求体里没有 repo 与 ref——
+   merge/release 的证据字段只有 files_changed、ci_checks、
+   branch_protection 等，没有仓库名、没有提交 SHA，
+   reader 不知道向哪个仓库的哪次提交求证，猜仓库
+   就是编造求证；② 服务端没有可信的求证通道保证——
+   github_app.resolve_app_token 对未安装 App 的仓库
+   返回 None（调用方回落 PAT），PAT 是调用方自己的
+   凭证，用它“核对”调用方自己的证据不是独立求证；
+   ③ 任务行里没有 repo/ref 列，服务端无法从任务 id
+   反推求证目标。接上实时求证须先改契约（请求体或任
+   务行加 repo + ref，安装保证或服务端侧可信 token），
+   那是契约决定，须协调员/用户在合轨时定；本轨不编
+   一个“看起来在求证”的假 reader、不把调用方证据
+   自己与自己比对后写成 verified。
+
+当前真实控制（写清，不拔高）：门禁强制证据齐全全绿
+（硬模式 fail-closed）；审计记 outcome 与 blocks
+（merge_gate_blocked / merge_task / release_task），
+但审计 detail 不保存证据体全文——事后追责能查到
+“谁在何时以何 blocks 通过/被挡”，查不到“当时提交
+的 ci_checks 原文”。谎报证据的发现仍靠事后审计与
+GitHub 侧记录比对，不是当场发现。本模块的核对器
+是为契约补齐后的接线准备的：届时服务端只需注入
+真实 reader 并把 verified=False（无论 skipped 还是
+mismatch）当作阻断，核对器本身不用改。
+
+零第三方依赖，只用标准库。本模块不 import cloud
+其它模块（reader 由调用方注入），不发网络请求。
+
+v7 机制第 6 项（生产证据 fail-closed live 接线，本批新增，
+只动本模块，不动其它 7 项）：
+- 新增可注入 reader 接口 LiveEvidenceReader（协议）：
+  get_checks(repo, ref) 与 get_branch_protection(repo,
+  branch)，返回结构含状态与原始证据（LiveChecksResult /
+  LiveProtectionResult，或等价 dict）。本模块的生产代码
+  里绝不实现真实 HTTP 调用、绝不读真实 token、绝不调
+  用真实 GitHub API——接口是未来真实 reader 的插入缝，
+  不是真实 reader 本身。
+- 新增 verify_live_evidence(claimed, reader, repo, ref,
+  branch=None)：协议 reader 或旧式 callable reader 均可；
+  无 reader、无 repo/ref、reader 失败、reader 返回与声
+  称不一致时 verified 一律 False；声称 CI 全绿但实时
+  数据失败/缺失时记 mismatch。比对规则与
+  verify_gate_evidence 逐项一致（共用 _compare），不另
+  造口径；空声称不由本函数放行——缺失证据由硬门禁
+  （merge_gate_hard）阻断，本函数只核对“声称了的项”。
+- 新增 live_gate_decision：端点层判定函数，verified
+  为 False 时返回 allowed=False、http_status=409、
+  status="blocked"、blocked=True（mismatch 与未核对用
+  不同 code 区分：live_evidence_mismatch /
+  live_evidence_unverified）；verified 为 True 时返回
+  allowed=True、http_status=200、status="allowed"。
+- 诚实残留（不得冒充已接线）：HTTP 端点 _merge_task /
+  _release_task 本批未接 live_gate_decision——当前无
+  生产 reader 可注入：以 reader=None 接线会挡住全部合
+  并/发布（fail-closed 的本意不是停摆），以桩 reader
+  接线则是假求证。真实 live 验证仍待 B6 真实 App 安装
+  与 B1 等用户侧事项，未在本批完成。本批不改 #238
+  auto_apply（仍 False）、不改 #247“纠正为 pass 本身
+  不解封”、不改 v1.1 契约、不改任何阈值（阈值仍

+
+1. 默认行为不变：钩子默认仍关。默认关是 #255 的设计
+   （显式启用才写行，关时行为与 gap 3 完全一致、无新表
+   无新行），不是 bug，不为“开箱即用”悄悄改成默认开。
+   把默认改成开，是用户/协调员在合轨时才能定的语义变
+   更，本轨不做。
+2. 显式开启路径唯一且可验证：Worker(attempt_ledger_hook

+   按 attempt_hook.py 规则 1-4 写行。本模块的
+   ledger_setup_report() 把“表是否齐、钩子是否开”分开
+   报告：表齐但钩子关 ≠ 就绪，钩子开但表不齐 ≠ 就绪。
+3. DDL 清单不另造：清单直接引用 attempt_ledger.PG_DDL
+   与 attempt_hook.PG_MARKER_DDL 两个常量（本模块不
+   复制 DDL 文本，复制就会漂移）。老形态表升级走
+   attempt_ledger.ensure_task_attempts_table 的统一列补齐

+4. 校验函数 verify_ledger_ready(conn)：只读探针——查两

+   schema，与 metrics-report 端点的只读纪律一致）。
+5. 生产 PG 手动 DDL 仍是运维侧动作：升级路径本身已在

+写失败只记一条 worker_attempt_ledger_failed 日志，绝不
+影响任务状态与返回值（attempt_hook.py 规则 7）。这是
+设计（指标台账不应挡任务），但与 #241 审计账本的
+fail-closed 不对称：一次写失败会让率悄悄少算一行，只
+有日志可查，没有重放/补写路径。
+
+本轨的对齐方式（写清边界，不悄悄改任一侧语义）：
+
+- 不把台账改成 fail-closed：台账写失败仍不挡任务、不
+  改任务状态、不改返回值（规则 7 原样保留）。让指标写
+  入能阻塞任务执行，是比丢一行更坏的 trade-off，
+  本轨不做。
+- 不把审计改成 best-effort：审计账本 fail-closed 原样
+  保留（审计是决策级证据，丢一行即链不可信；台账是
+  指标，丢一行只影响率的分母/分子，且可事后补）。
+- 不对称的剩余部分用“不丢”补齐：写失败时除日志外，
+  再向 worker 侧 outbox 文件追加一行 JSONL（task_id、
+  outcome、error、failed_at）；运维事后调
+  replay_failures() 把 outbox 行经 record_attempt 补写
+  进台账（append-only，attempt_no 按 MAX+1 续号），
+  成功补写的行从 outbox 清除，仍失败的行保留待下次。
+  于是失败不再是“只有日志可查”，而是“可数、可重放、
+  重放后可验证行数补齐”。
+
+诚实边界：
+- outbox 本身也是 best-effort：outbox 追加失败（如
+  磁盘满）只记日志，不抛、不挡任务——此时仍退回首轮
+  状态（仅日志可查），但这条路径本身已被测试钉住
+  （追加失败不抛异常）。
+- 重放无幂等键：record_attempt 没有去重键；若原始写
+  入实际已提交、只是提交确认丢失（ambiguous commit），
+  重放会多写一行。重放是运维手动动作：重放前须核对
+  task_attempts 是否已有该任务的对应行，确认缺失再

+- 本模块只是评分卡输入模型，不是产品功能。不得声称 MCDT 已是
+  产品功能、已接入生产评分、已跑通真实审计循环。
+- 本模块不改任何生产行为：不碰 #238 auto_apply（保持 False）、
+  不碰 #247“纠正为 pass 本身不解封”、不改 v1.1 契约、不接线到
+  build_scorecard / 服务器端点 / 门禁。本模块的输出只是“每维的
+  得分输入”，调用方是否采用、如何采用，须另行拍板。
+
+设计（v7 机制第 8 项，只做这一项）：
+- acceptance_node（验收节点）：一项可验收的结果主张，至少含
+  id、title、acceptance_criteria（列表）、status、evidence_refs。
+  另含 dimension：该节点映射到哪一维（7 维 id 之一）；无 dimension
+  或 dimension 非法时该节点不映射到任何维（记入未映射清单），
+  绝不靠猜测、按 id 前缀、按其它维借分。
+- key_fact_node（关键事实节点）：一项支撑/证伪验收的关键事实，
+  至少含 id、fact、status、source。另含 dimension：与验收节点同
+  规则；无 dimension 的关键事实不影响任何维。
+- status 词汇（两类节点共用）：pending / pass / fail / unknown。
+  pending = 尚未判定；unknown = 未知/未验证；fail = 已证伪或未达标；
+  pass = 已验收通过。其它任何值一律按 unknown 处理（fail-closed，
+  不把拼写错误读成通过）。
+
+映射到哪几维（写清，不留含糊）：
+- delivery_quality（交付质量）：验收节点证明交付结果达到验收标准。
+- gate_audit（门禁与审计有效性）：验收节点证明门禁真实拦截、
+  审计结论可复核。
+- arch_contract（架构与契约一致性）：验收节点证明契约冻结、
+  架构 / 目录 / 导入一致。
+- 其余四维 test_coverage、security_ledger、cost_quota、ops_scale：
+  本项不预设节点。无对应验收节点时一律记 unknown，并在
+  missing_items 里说明；不得用过程指标（测试数、覆盖率）填补，
+  不得从其它维借分。注意 test_coverage 尤其如此：覆盖率数字
+  本身是过程指标，即使调用方手头有覆盖率，也不能因此把
+  test_coverage 从 unknown 改成 pass/fail——只有映射到该维的
+  验收节点状态变动才能改分。
+
+映射规则（nodes_to_dimension_inputs）：
+(a) 某维无对应验收节点时，该维输入为 unknown（不得用过程指标填补）。
+(b) 过程指标（test_count、coverage）只作为证据字段透传，绝不直接
+    进入得分输入：它们只出现在返回值的顶层 process_evidence 里，
+    绝不出现在任何一维的 score_input / status / basis 里。只改
+    test_count / coverage 而节点状态不变时，每维的得分输入不变；
+    只改节点状态（pending -> pass 或 pass -> fail）时，映射输出变化。
+    节点 dict 上附带的 test_count / coverage 等额外键同样被忽略，
+    只读 id / title / acceptance_criteria / status / evidence_refs /
+    dimension（验收节点）与 id / fact / status / source / dimension
+    （关键事实节点）。
+(c) 节点状态为 fail 时对应维不得为 pass；节点状态 unknown 时对应维
+    为 unknown。具体聚合（fail-closed，优先级 fail > unknown >

+    - 任一映射验收节点 fail -> 该维 fail；
+    - 任一映射关键事实 fail -> 该维 fail（已证伪的关键事实不得
+      让该维通过，即使验收节点全 pass）；
+    - 否则任一映射验收节点 unknown 或 pending -> 该维 unknown；
+    - 否则任一映射关键事实 unknown 或 pending -> 该维 unknown
+      （支撑事实未验证，不得宣称通过）；

+"""合并门禁：主分支保护 + 目录隔离（纯函数，无网络、无 GitHub 调用）。
+
+A1 声明（服务端唯一门禁是 hard，不要拿本模块的模式推断服务端）：
+- 自 A1 起，服务端 POST /tasks/{id}/merge 一律按
+  cloud/merge_gate_hard 的 hard 求值；环境变量
+  CLOUD_MERGE_GATE_MODE 与请求体 merge_gate_mode 在服务端一律被
+  忽略，旧值 record/enforce/off 不再是服务端可选项。
+- 本模块以下写到的 record/enforce/off 只是 #209 纯函数的历史语义：
+  它们只描述 evaluate_merge_gate / gate_from_request 这两个纯函数
+  本身，不再接线到任何服务端端点；纯函数单测保留这些语义，不代表
+  服务端会按此放行。需要服务端行为时只看 merge_gate_hard。
+
+背景与诚实边界（先读，再用）：
+- 本模块**不能**替仓库开通主分支保护。保护是 GitHub 仓库设置，
+  只能由仓库管理员在 GitHub 侧开通；GitHub App id 5476837 的权限
+  也不会自动变化，新权限需安装方重新接受。本模块只能在调用方
+  明确告诉它保护状态时做门禁，绝不声称“已保护”。
+- 保护状态的唯一来源是调用方传入的值或环境变量
+  CLOUD_BRANCH_PROTECTION（protected / unprotected，未设即
+  unknown）。unknown 不是“通过”，是“未知”：门禁把它记为风险，
+  但不因此阻断——因为本服务没有可信渠道去 GitHub 核实，拿未知
+  当未保护去硬堵，会把当前所有合并（当前仓库本身未保护）全停掉。
+  想把门禁武装起来，运维要显式设置该环境变量为 unprotected，
+  再由调用方在每次合并时传确认，或把模式切到 enforce。
+- 目录隔离复用 v0.3 技能的检查口径（见
+  cloud/skills/software-engineering/SKILL.md“目录与分支规则”）：
+  人 / 宿主跑 ``git diff --name-only $(git merge-base origin/main
+  HEAD)...HEAD``，逐项核对每个文件是否落在拥有目录内，契约变更
+  经协调员批准的文件除外。本模块不另造一套口径：
+  ``check_directory_isolation`` 就是这条规则的可执行版，
+  ``directory_diff_command`` 返回的正是 v0.3 文本里的命令。
+  v0.3 之前服务端合并端（POST /tasks/{id}/merge）只改任务状态，
+  不做 git 合并、不做目录检查、不做保护检查——那是本模块要补的
+  缺口，不是重复造检查。
+
+模式（以下仅为本模块纯函数的历史语义，不是服务端行为；服务端
+唯一门禁是 hard，见模块头 A1 声明）：
+- record（纯函数默认）：未保护时必须显式确认（explicit_confirm）才放行；
+  无确认时阻断，错误码 branch_protection_risk_unconfirmed。
+  确认只覆盖“保护风险”，绝不覆盖目录隔离违规——越目录的写
+  只能靠 approved_exceptions（契约变更批准）放行，不能靠确认蒙混。
+- enforce：未保护时一律阻断，确认也不放行。切到 enforce 之前
+  必须先由用户决定并开通保护：升级 Pro、公开仓库、或保持现状
+  纪律 + 记风险——三者都是用户侧决定，代码里只留开关，不替选。
+- off：门禁显式关闭，只记风险不阻断。off 必须显式设置，
+  非法模式值不会悄悄落到 off，而是回落到 record（fail-safe）。

+  纯函数（record 默认、无证据不阻断、unknown 只记风险不阻断），
+  自 A1 起不再接线到任何服务端端点；它们的 record/enforce/off
+  语义是纯函数的历史语义，不是服务端行为，不得据此推断服务端
+  会放行（见 cloud/merge_gate.py 头部的 A1 声明）。
+- 服务端唯一门禁就是本模块的 hard：POST /tasks/{id}/merge
+  一律按 hard 求值；环境变量 CLOUD_MERGE_GATE_MODE 与请求体
+  ``merge_gate_mode`` 在服务端一律被忽略——旧值 record/enforce/off
+  不再是可选项，设了也等同 hard，不存在“显式降级”的服务端路径。
+  （此前 hard_mode_from_env 曾把显式 record/enforce/off 原样沿用，
+  A1 已删除该解析与 HARD_MODES：删模式，不是改默认值。）
+
+模式（服务端唯一：hard）：
+
+硬门禁五项（全部是调用方在 /merge 请求体里提交的证据；
+本服务没有可信渠道直连 GitHub 核实，所以门禁强制的是“证据齐全
+且全绿”，不是“服务端已向 GitHub 求证”——这条诚实边界必须写清，
+调用方谎报证据不在本模块的验证范围内，由审计（第 3 轨）与
+PR/Checks 的只读核对去覆盖）：
+  ① CI 全绿：``ci_status`` 必须为 ``"success"``，且 ``ci_checks``
+     非空、每项 status 均为 ``"success"``，且 ``required_checks``
+     非空、每项都在 ``ci_checks`` 里且为 success。空
+     ``required_checks``（``[]``）= 未配置，按分支保护 payload
+     的同一口径处理（见 docs/merge-gate-branch-protection.md），
+     不是“没有必须项所以通过”。
+  ② 目录隔离：复用 #209 的 ``check_directory_isolation``（v0.3 口径：
+     merge-base 范围 ``git diff --name-only``，拥有目录前缀检查，
+     含 ``apps/web2`` 非子目录边界与 ``../``、绝对路径逃逸）。
+     ``files_changed`` 缺失 = 无证据，直接阻断（#209 里是跳过，
+     硬模式里是阻断，这是本轨改动的核心之一）；越目录只能靠
+     ``approved_exceptions``（协调员批准的契约变更文件）放行，
+     显式确认绝不覆盖目录违规。
+  ③ 合同版本：``contract_version`` 非空，且 ``contract_frozen``
+     为 true；若同时给了 ``contract_expected_version``（冻结版），
+     两者必须相等，否则阻断。服务端没有独立的合同版本存储，
+     冻结版由调用方（协调员侧）声明， mismatch 时阻断。
+  ④ 协调员批准：``coordinator_approved`` 必须为 true；缺失与
+     显式 false 用不同的 block 码区分（缺证据 vs 已否决）。
+  ⑤ 无未解决评审意见：``unresolved_review_comments`` 必须为 0
+     （整数）或空列表；缺失 = 无证据，阻断；大于 0 / 非空 = 阻断。
+
+分支保护（硬模式下的第六条隐含项，来自 #209 的保护定义）：
+  ``branch_protection`` 必须为 ``"protected"``。``"unprotected"``
+  即使带 ``merge_gate_confirm`` 也阻断——硬模式没有“确认即放行”
+  的逃生口（旧 record 模式下确认可覆盖保护风险的语义已随 A1
+  删模式一并失效，服务端不再有确认放行的路径）。``"unknown"``
+  （未声明或非法值）同样阻断：unknown 不等于 protected，这是
+  #209 里“unknown 只记风险”的过渡语义在硬模式下的收紧。
+
+与第 3 轨（独立审计 + 自动推回）的接口约定（本模块不造推回状态机）：
+  - 阻塞依据 = 409 响应里的 ``merge_gate`` 对象：``mode``、
+    ``blocks``（稳定的机器可读码，下面的 _BLOCK_DESCRIPTIONS 有
+    逐条中文说明）、以及 ``ci`` / ``directory`` / ``contract`` /
+    ``coordinator`` / ``reviews`` 五个分项。推回包逐条取 blocks，
+    不要解析审计 detail 文本。
+  - 审计依据 = 每次门禁阻断写一条 ``merge_gate_blocked`` 审计
+    （action 名固定，detail 为 ``"<task_id> mode=<mode>
+    blocks=<逗号分隔的 blocks>"``），任务状态不变（UPDATE 不执行）。
+  - 门禁结论是单次调用的判定，不持久化为任务状态：一次 200 不
+    代表之后另一次合并自动通过；修复后必须重新提交完整证据、
+    重新走全部五项（完整重审，非只审改动点）。
+  - 本模块不建推回任务、不发通知、不改任务状态机：推回执行、
+    轮次上限、升级路径全部归第 3 轨。

+"""Metrics collection and feedback loop for agent-task quality.
+
+Zero third-party dependencies; standard library only. This module
+imports no ``cloud.*`` module: it computes over plain record dicts so
+the collection logic is testable without a database, and so the
+report shape is identical whether the records came from the control
+plane (``server._metrics_report`` reading the attempt ledger), a
+test fixture, or a hand-built record list.
+
+Definitions (pinned here, not left to each caller):
+
+- A task counts toward a rate only when it reached a terminal status
+  (``completed`` / ``merged`` / ``failed`` / ``merge-failed``).
+  ``interrupted`` is deliberately NOT terminal: platform-interrupted
+  tasks auto-resume as fresh runs, so counting them as failures
+  would punish a platform event, not the agent.
+- First-pass green: terminal task whose ``attempts`` == 1 and whose
+  status is ``completed`` / ``merged``.
+- Defect: a task with ``defects`` > 0, where ``defects`` is the count
+  of failed CI/audit rounds or follow-up rounds for that task. Since
+  audit gap 3 these numbers come from the ``task_attempts`` ledger
+  (``cloud/attempt_ledger.py``: one row per real attempt, aggregated
+  by the endpoint); a task with no ledger rows must still pass
+  ``None`` -- and the rates then come back as ``None`` with
+  ``*_known`` False. An unknown rate is never reported as 0: 0
+  would claim "no defects", which is a decision-grade lie.
+- Rework: terminal task with ``attempts`` > 1. Same None discipline.
+- Per-task cost reuses the #212 dual-column discipline from
+  ``cloud.cost``: priced USD micros and unpriced actual tokens are
+  reported in separate columns. ``total_usd_micros`` is ``None``
+  whenever any task's cost is incomplete (no cost rows, or unpriced
+  actual tokens > 0); the priced partial sum is still shown, labelled
+  ``priced_usd_micros_partial``, so nobody mistakes it for a total.
+  Unpriced cost is never folded into 0.
+
+Feedback (``evaluate_feedback``) is deliberately a pure function
+returning action records, not an auto-applier: an action says WHAT
+should change and WHY, with its evidence attached; applying it to
+routing or to the audit standards is a separate, approved step
+(see ``docs/arch-conformance-metrics.md``). The rules are testable:
+
+- defect rate for a category above threshold -> ``tighten_check``
+  for that category's check;
+- first-pass rate below its floor -> ``route_with_extra_audit``;
+- a check whose violations are overturned on review above
+  threshold -> ``recalibrate_check`` (review the threshold, do NOT
+  auto-apply a new one -- a check that fires wrongly must not
+  silently widen itself).
+
+Thresholds passed in are labelled by source in the report. The
+defaults in ``DEFAULT_THRESHOLDS`` are starting values for tests,
+NOT human-approved production thresholds: the report marks them
+``thresholds_source: "default_unapproved"`` until a human approves a
+set, and a report built on unapproved thresholds is still usable
+for collection -- it is just not decision-grade on its own.
+
+Golden tasks: a report is ``decision_ready`` only when a golden set
+has been human-approved (``approved_by`` + ``approved_at`` present
+and at least one golden task listed). Until then the golden section
+reads ``status: "pending_human_approval"`` and the report says so
+plainly; the sample-only set that exists today must never be
+presented as decision-ready. This module never invents golden tasks.

 never runs a model turn itself and never talks to any provider.

+Rule routing (v0) is deliberately narrower than that: it only fills
+in the model for tasks that did not specify one, using structural
+signals already stored on the task (``plan``, ``goal_mode`` /

+``plan``, ``executor`` or any quota, never switches provider/gateway,

+    never fetched from a provider, so a stale directory is
+    the operator's responsibility to fix; the dry-run tool
+    reports capability mismatches before activation.
+
+    Shadow mode returns the worker default as ``chosen_model`` and the
+    policy tier model as ``suggested_model`` with ``applied=False``:
+    it observes without changing behaviour. This function is pure: it

+"""QA full-chain checks: self-test, PRD coverage, agent six,
+cross-client matrix, G5 gate, regression scope, dual signatures.
+
+Pure functions, standard library only. This is the QA half of the
+audit-hardening track; the audit half lives in
+``cloud/audit_pushback.py``. The two are different checks and
+neither report substitutes for the other: the QA matrix proves
+the business links run on every selected client, the independent
+audit re-runs the exact artifacts. The checklist therefore has
+two separate signature seats (QA matrix signer, independent
+audit signer) and both must be present and different, or the
+round does not pass.
+
+Honest exceptions, written as rules rather than judgement calls:
+
+- On a Linux host, iOS / Android / macOS cannot be compiled.
+  Their honest verdict is ``"code_review_plus_web_core"`` -- never
+  ``"pass"`` / ``"build_pass"``. An untested client is never a
+  pass, even with a reason: the reason makes the matrix
+  *accounted for*, it does not make QA pass.
+- QA passing is not user acceptance. G6 acceptance is ticked
+  only by the user; QA, audit, pushback, and rebuild can never
+  tick it (see ``check_g6_guard`` in ``audit_pushback``).
+
+Counting relation to pushback / rebuild (single story, no second
+counter): one failed round counts once for its module, however
+many QA links failed in that round -- links are failed items
+inside the round, not extra failures. A standalone G5 QA failure
+(without an audit round) runs the G5 defect loop (back to G4,
+re-regress in G5) and does not by itself increment the module's
+audit/acceptance failure count; it increments the count only
+when the round reaches an audit failure or a QA-acceptance
+sign-off failure, recorded with source ``"audit"`` or
+``"acceptance"`` respectively. A targeted fix round and a
+rebuild both re-run the QA matrix: the re-audit must re-run the
+failed links listed in the pushback package (see
+``check_reaudit_reran_links``), not just unit tests.

+"""Release gate, unified: thin adapter over the single evaluator.
+
+The sole release evaluator is
+``cloud/audit_loop_wiring.evaluate_release_gate``. The live
+endpoint (``POST /tasks/{id}/release``,
+``handler_lifecycle._release_task``) calls it directly; this
+module only adapts its decision into the legacy shape below so
+the contract tests in ``cloud/tests/test_release_gate.py`` keep
+pinning the same behaviour. There is no second evaluator in
+this tree: do not add evaluation logic here, change it in
+``audit_loop_wiring`` and update this adapter's translation.
+``deploy.py`` remains an operator script, not a release endpoint
+(see ``docs/release-gate-and-ledger-anchor.md``).
+
+What this module IS:
+
+- A pure, read-only adapter: ``evaluate_release`` delegates to
+  the wiring evaluator, which re-reads the hash chain through
+  the SAME reader the merge endpoint uses and ANDs it with a
+  FRESH hard-gate evaluation supplied by the caller. It never
+  appends to the chain, never calls ``AuthStore.audit``
+  (which writes a chain row in the same transaction), never
+  commits, and never deploys anything. Checking must not move
+  the chain head: otherwise the check itself would invalidate
+  the external anchor taken before it.
+- The contract the live endpoint implements. The endpoint
+  (``POST /tasks/{id}/release`` in ``handler_lifecycle``) calls
+  the wiring evaluator directly and maps its decision to HTTP
+  exactly as documented in the companion doc; this module only
+  adapts that decision into the legacy shape for its contract
+  tests, it is not a second evaluation path.
+
+What this module is NOT:
+
+- It is not a merge gate. Merge (``POST /tasks/{id}/merge``)
+  and release are separate decisions with separate re-checks:
+  a merge-time 200 is never a release pass. The live endpoint
+  calls the wiring evaluator at release time, with fresh
+  evidence, even if the task was merged minutes ago.
+- It is not a deploy gate. ``deploy.py`` deploys the platform
+  itself (host release directory + unit restarts) and is
+  deliberately outside this gate; see the companion doc.
+- It does not decide task status, auth, or publication. Status
+  (``task_status``) and the hard-gate evidence (``hard_gate``)
+  are caller-supplied inputs, so the evaluator can be tested
+  without a server, a task row, or a publication step. When the
+  caller omits an input, the evaluator fails closed on that
+  input instead of assuming it (missing hard-gate evidence
+  blocks; an unmerged status blocks when a status is given).
+
+Decision shape (``evaluate_release`` return value)::
+
+    {
+        "allowed": bool,            # True only if every check passes
+        "http_status": 200 | 409,   # the status the endpoint maps to
+        "code": str,                # machine code, see below
+        "blocked_by": str | None,   # primary source, or None if allowed
+        "blocked_sources": [str],   # every applicable source, in order
+        "blocks": [str],            # hard-gate block codes, if any
+        "failed_checks": [str],     # audit-pushback failed checks, if any
+        "round": int | None,        # pushback round, if any
+        "modules": dict,            # per-module block detail, if any
+    }
+
+Machine codes (``code`` / ``blocked_sources``):
+
+- ``release_allowed`` -- every check passed.
+- ``release_requires_merged`` -- a task status was supplied and
+  it is not ``"merged"``. Release is a post-merge act; an
+  unmerged task has nothing to release.
+- ``release_blocked_state_unavailable`` -- the chain could not
+  be read at all (anything other than the reader's own
+  missing-table rule, which means "no chain has ever been
+  written" and is inherited from #247 unchanged). Fail-closed:
+  an unreadable chain is never read as "no block".
+- ``release_blocked_hard_gate`` -- the fresh hard-gate
+  evaluation (five checks: CI, directory, contract, coordinator,
+  reviews, plus branch protection) did not allow. The failing
+  codes travel in ``blocks`` verbatim, so the caller can tell
+  a hard-gate block from an audit block without parsing text.
+- ``release_blocked_audit_pushback`` -- the re-read chain says
+  a pushback is still open (``release_blocked`` from the same
+  reader the merge endpoint uses). This is the #247 reader's
+  verdict at release time, not a cached merge-time value.
+
+When several sources block at once, ``blocked_sources`` lists
+all of them (chain-unavailable dominates and short-circuits,
+because without a chain read no other verdict is trustworthy),
+while ``blocked_by``/``code`` name the first source in
+evaluation order: chain read, then task status, then hard gate,
+then audit pushback. The endpoint must return the full
+decision object, not just the first code, so an operator can
+see that fixing one source still leaves another blocking.
+
+CORRECTED-to-pass does NOT unblock (inherited, not invented):
+
+The reader already implements the #247/#244 resolved semantic:
+a meta-review correction to ``pass`` schedules a re-audit, it
+does not release the gate; only a fresh passing verdict or a
+passing re-reviewed pushback row unblocks. This evaluator adds
+no special case for corrections, so the release path cannot
+drift from the merge path: the same chain, read through the
+same reader, gives the same answer at both gates. The contract
+tests pin this: corrected-to-pass with no new passing
+conclusion stays blocked at release, exactly as at merge.

+"""Routing policy dry-run (v0d): validate before applying, never apply.
+
+A routing policy takes effect the moment a worker loads it from the
+host env -- there is no CI gate for an env change. A typo in a tier
+mode silently drops that tier, a bad model name is never checked
+against a whitelist (models are not whitelisted by design), and a
+policy file that fails to parse is silently ignored by the loader
+(fail-closed to the worker default, but also silently). This module
+surfaces all of that BEFORE the policy is applied, and it never
+applies anything itself: it only reports what WOULD happen if the
+given policy document were loaded.
+
+What it reports, per tier (plan / goal / default):
+* the effective model and mode, and whether the mode came from an
+  explicit tier mode or from the global mode,
+* tiers that were dropped, and why (invalid tier mode, no model,
+  unrecognised entry) -- a dropped tier is a BLOCKER, not a warning
+  to skim past, because applying the policy would silently not route
+  that tier,
+* tiers absent from the document (worker default, not routed),
+* unknown tier names in the document (ignored by the parser),
+* whether any tier would actually activate on next dispatch,
+* capability checks (v8): per tier, whether its model meets
+  its requires against the policy's model_capabilities
+  directory -- an active tier that fails or cannot be verified
+  is a BLOCKER (it would block dispatch at the worker
+  capability gate); a shadow/off tier with the same problem
+  is a warning only.
+* gateway model check (Audit fix 3, I1): the same requires,
+  checked against the sub2api gateway model -- the model
+  production actually dispatches, which is NOT the tier
+  model. The gateway model comes only from env
+  (CLOUD_SUB2API_DEFAULT_MODEL); this module never calls
+  the relay to list models. An active tier whose requires
+  the gateway model fails or cannot verify is a BLOCKER;
+  a shadow tier is a warning only. "运营方须先把网关模型
+  写进能力目录" is now a checkable rule, not a comment.
+
+What it does NOT do, honestly:
+* It does NOT validate model names against a provider or relay
+  catalog. Task models are deliberately not whitelisted in this
+  codebase (the relay catalog changes), so a model typo here is
+  reported as "unverified, not whitelisted" only if the caller
+  passes a known-model set; without one, model names are reported
+  as-is and the caller must check them against the relay catalog
+  themselves. This module never invents a catalog.
+* It does NOT check shadow sample counts. That is the shadow
+  report's job (GET /routing-shadow); a dry-run that said "ready
+  to activate" without sample data would be fabrication.
+* It does NOT change host env, worker state, or any file. The CLI
+  exits 1 when the policy is invalid or any tier was dropped or
+  unknown, so a deploy script can gate on it; warnings alone
+  (no version, fallback_models present) do not block, but are
+  always printed.
+
+Loading order, mirrored from load_routing_policy in models.py:
+file (CLOUD_ROUTING_POLICY_FILE) first, then JSON
+(CLOUD_ROUTING_POLICY_JSON) overrides whole tier entries (not
+per-field: a JSON tier entry replaces the file's tier entry
+entirely), then CLOUD_ROUTING_MODE overrides the GLOBAL mode
+only -- it never overrides an explicit tier mode. Failed file/JSON
+sources, which the loader silently ignores, are reported here as
+warnings instead of being swallowed.

+"""Routing v0b: shadow evaluation (read-only, never auto-activates).
+
+This module answers the one question routing v0 left unanswered:
+"is there enough shadow evidence to review a tier for activation?"
+It does NOT decide activation, and it does NOT claim a counterfactual.
+
+Why the counterfactual is explicitly not measured
+--------------------------------------------------
+In shadow mode the suggested model never runs. The task's actual
+outcome (status, tokens, cost) is the outcome under the chosen
+worker-default model, not under the suggested model. So this report
+can measure, per tier:
+
+* how many distinct tasks were routed (one task = one sample,
+  retries do not double-count),
+* their status breakdown under the chosen model,
+* the distribution of suggested models,
+* total tokens and priced USD, with unpriced tokens kept separate,
+
+but it cannot say the suggested model "would have been cheaper or
+better". Any report that compared shadow suggested cost to actual
+cost as if both had run would be fabrication. The field
+``counterfactual`` in every report says ``not_measured`` for exactly
+this reason, and the top-level recommendation never activates a tier:
+activation stays a manual decision, plan tier first, per the v0 design.
+
+Data sources, and their limits
+-------------------------------
+* ``audit_log`` rows with action ``worker_routing``. The v0 format
+  was ``<task_id> tier=<tier> source=<source> applied=<bool>``;
+  v0b extends it with ``suggested=<model|-> chosen=<model|->``
+  (see worker.py). Rows in the old format parse fine, with
+  ``suggested_model`` reported as unknown and counted separately
+  (``suggested_unknown_n``), never guessed.
+* ``tasks`` rows for status and explicit-model separation. A task
+  with a creation-time ``model`` is explicit: routing never audits
+  it (decide_routing returns source ``explicit`` and the worker
+  does not audit), so explicit tasks are counted separately and
+  never inflate a tier's sample count.
+* ``cost_records`` aggregated per task. USD here is whatever the
+  cost store recorded: with the current proxy-price overlay that is
+  the gpt-6.1-sol proxy price, NOT the relay's actual bill, and
+  unpriced rows contribute tokens but no USD. The report keeps
+  ``usd_micros`` (priced only) and ``unpriced_tokens`` apart and
+  labels USD as proxy-priced when any unpriced tokens exist.
+
+Pure functions only: this module never touches a DB, a provider,
+or an environment variable, so it is unit-testable with plain dicts.
+The server endpoint (GET /routing-shadow) is the only DB reader,
+and it passes already-aggregated rows in.

+
+收敛前分层口径散在各处注释里，本模块把它钉成可单测

+2. 失联清理判定（cleanup_decision）：worker
+   _reap_kill_requests 的状态与心跳两道门——任务必须
+   已是 interrupted，且心跳停滞超过阈值（心跳取
+   COALESCE(last_heartbeat, updated_at)，与

+   跳过）。请求 pending、执行器有 kill_container、容器
+   名由任务 id 派生这三道门仍在 worker 侧，不进本层：
+   本层只判“该不该杀”，不执行杀。

+"""评分卡差分审计与涨幅停表（v7 机制第 3 项，纯函数 + 标准库 only）。
+
+只做这一项，不碰其它 v7 机制项。本模块不改动
+``cloud/audit_loop_driver.py`` 的语义，也不改动
+``cloud/audit_scorecard.py``：它是评分卡侧的停表机制，不是
+审计循环本身。审计循环的 pushback 上限 3、重建预算 1、
+版本变更重置思路只作参考，不在本模块里复写或放宽。
+
+三张表分开记分，绝不只记平均分
+--------------------------------
+每轮 ledger 条目同时记 ``code`` / ``production`` / ``product``
+三张表各自的分数（任一表未知记 ``None``，不估算）。
+``average_for_reference_only`` 只作参考信息，停表判定只看
+代码表（``code``），绝不用平均分判定——与 audit_scorecard
+“平均分绝不能作为达标依据”的规则一致。
+
+阈值未拍板
+----------
+``STAGNATION_THRESHOLD`` 的值 0.5 标注
+``source="test_default_unapproved"``（测试默认值、未拍板），
+与 audit_scorecard 的 ``DEFAULT_THRESHOLDS`` 口径一致。
+生产阈值须用户拍板后由调用方显式传入 ``threshold`` 才能替换；
+本模块绝不把测试初值写成生产值，也不替用户决定 B/C 与阈值。
+
+与已定语义的关系（本模块不改它们）
+----------------------------------
+- #238 ``evaluate_feedback`` 的 ``auto_apply`` 保持 False；
+  本模块没有 auto_apply 路径。
+- #247 纠正为 pass 本身不解封；本模块不做解封、不做
+  re-audit、不碰门禁状态，只返回停表判定。
+- v1.1 契约不变；本模块不增维、不改 7 维定义。
+- 停表触发时返回 ``escalate`` 语义，不再自动推回：
+  结果里 ``auto_pushback`` 恒为 False，且
+  ``escalation_grants_user_acceptance`` 恒为 False
+  （escalate 从不 tick 用户验收，与 audit_loop_driver 一致）。
+
+(a) 差分范围输入：``audit_scope(baseline_snapshot, current_snapshot,
+claimed_fixed)``
+----------------------------------------------------------------
+快照形式（二选一，两种都接受）：
+- 文件路径集合：``set`` / ``list`` / ``tuple``，元素为路径字符串。
+  此时变更 = 对称差（新增 + 删除）；交集 = 未变更。
+- 快照 dict：键为路径，值为内容指纹（hash/内容字符串），或
+  ``{"files": <路径集合或路径->指纹 dict>}`` 形式。
+  此时变更 = 新增 + 删除 + 同路径指纹不同（修改）；指纹相同
+  的路径 = 未变更。
+
+审计范围 = 变更文件 + 调用方声称修好的项（``claimed_fixed``）。
+未变更文件进 ``out_of_scope``，不进审计包；基线外（即不在
+变更集内、也不在声称修好集内）的文件一律不进包。
+``claimed_fixed`` 是项 id（检查名/维 id 等字符串），不是文件
+路径；它与文件集分开返回，调用方按项复核，不与文件混算。
+
+(b) 涨幅 ledger：``ScorecardGainLedger``（内存）与
+``SqliteScorecardGainLedger``（SQLite）
+------------------------------------------------
+- 内存 ledger：append-only 列表，``append()`` 存规范化后的
+  条目副本，``rounds()`` 返回副本（调用方改返回结果不影响
+  已存条目）。模块级函数 ``append_round`` / ``read_rounds``
+  接受 ledger 对象或普通 list，方便测试与调用方复用。
+- SQLite ledger：同一列名、同一追加语义的 SQLite 表
+  ``scorecard_gain_rounds``（见 ``SQLITE_DDL``），用标准库
+  ``sqlite3``、``?`` 占位符。``PG_DDL`` 是与之列对应的
+  Postgres 建表语句文本，仅作仓库 DB 模式兼容写法：
+  真实 PG 在本项中不接通、不执行、不验证，只用
+  SQLite（内存或文件）测试并明说。
+- 条目校验：``rubric_version`` 必须为非空字符串，否则
+  ``ValueError``；三张表分数各为 ``None`` 或 0-10 的数，
+  超范围或非数值 likewise ``ValueError``；bool 不算数值。
+
+(c) 停表判定：``check_stagnation(history)``
+--------------------------------------------
+- 只看 trailing 同 rubric_version 序列：从最新一轮往回取
+  与最新轮 ``rubric_version`` 相同的连续轮次；改标尺即新
+  序列，旧标尺的轮次不连算。
+- 该序列内相邻两轮代码表分数之差为一轮涨幅；分数为 1 位
+  小数（与 audit_scorecard 的 _round1 一致），涨幅按
+  1 位小数舍入后再与阈值比较，避免 8.8-8.3 这类二进制
+  浮点残差把恰好 0.5 误判为 <0.5。
+- 涨幅 < 阈值（含负涨幅，即代码表下滑）记为小涨幅；
+  涨幅 >= 阈值，或涨幅未知（任一端分数为 None），打断
+  连续计数。连续两轮小涨幅（即该序列内最近两次涨幅
+  均为小涨幅，至少需要 3 轮）即触发停表。
+- 触发返回 ``{"decision": "escalate", "reason": "stagnation", ...}``；
+  未触发返回 ``{"decision": "continue", ...}``。两种结果都
+  不含 pushback 动作；触发时 ``auto_pushback`` 为 False。

+"""评分卡标尺版本化：仅追加的持久存储（v7 机制第 1 项）。
+
+问题：cloud/audit_scorecard.py 的 DEFAULT_THRESHOLDS 只存在于
+代码里，标尺一改，旧标尺下的分数就再也算不出来、也对不上
+——审计员每次重审都在新标尺下重算旧分，基线漂移就是这么来的。
+
+解法（复用 audit_loop_driver 的键思路，不复用它的表）：
+- audit_loop_driver 以 (module_id, contract_version) 为键，
+  合同版本一变，计数与预算全部重置、旧版本状态原地不动。
+  这里同理以 rubric_version 为键：标尺改动 = 写一个新版本行，
+  旧版本行原地不动；同一证据在旧版本下重算，分数逐字相同。
+- 不复用 audit_loop_state 表：那张表存的是循环状态
+  （pushback 轮次、失败计数），标尺不是循环状态，混表会让
+  两类数据的生命周期互相牵连。故新开两张表（见下）。
+
+两张表（SQLite / Postgres 兼容写法，沿用 audit_loop_wiring 的
+conn + ``?`` 占位符 + CREATE TABLE IF NOT EXISTS 模式；类型只用
+TEXT / REAL，不用任何一方专属类型，不用自增列）：
+- scorecard_rubric_versions：标尺版本行，主键 rubric_version。
+  列：rubric_version、thresholds_snapshot（归一化阈值表的
+  canonical JSON）、baseline_head（该版本锚定的基线提交，
+  调用方显式传入，本模块不跑 git、不猜 HEAD）、
+  thresholds_source（user_approved 仅当全部条目都已拍板，
+  其余一律 test_default_unapproved）、created_at。
+- scorecard_snapshots：已算出的卡片行，主键
+  (rubric_version, evidence_sha256)。列除主键外还有
+  baseline_head 与 thresholds_snapshot（从版本行反规范化而来，
+  让单行快照自带审计三要素，不必联表也能核对）、
+  scorecard_json（build_scorecard 的完整输出）、created_at。
+  选型理由：只存版本行 + 现算也能复现旧分（scorer 是纯函数），
+  但快照行让“旧行分数不变”成为可直接读回的事实而非“重算
+ 碰巧一致”的推论；快照不存证据原文，只存证据的 SHA-256，
+  避免证据体在库里再留一份副本。
+
+仅追加（append-only），这是本模块的核心承诺：
+- 对外 API 只有 create / get / list / latest / score / record /
+  get_snapshot，没有任何改旧行、删旧行的方法；重复建同一
+  版本号直接报 ValueError（主键冲突转译，不做 upsert）。
+- 同一 (rubric_version, evidence) 重复 record 时返回已存行的
+  卡片原样，不覆盖、不合并。
+- 本模块防的是“走正常 API 的误写”（与 ledger 的触发器同款
+  诚实边界）：能直接拿连接跑 SQL 的人当然能改库，库内机制
+  拦不住超级用户；可信锚点仍须落在库外（如导出的行哈希）。
+
+事务边界：沿用 audit_loop_wiring 的做法——本模块的写函数
+在写后 commit；调用方若想把多写包进同一事务，应直接用
+底层的 INSERT 语句而非本模块的写函数。读函数不 commit。
+
+诚实边界：
+- 阈值本身仍不由本模块拍板：thresholds_source 的判定与
+  audit_scorecard 一致，测试默认值永远标
+  test_default_unapproved；user_approved 只能由调用方显式
+  传入全部已拍板条目。
+- 未在真实 Postgres 上验证：SQL 只用两端通用的写法，
+  并以 SQLite（文件库 + :memory:）与假连接（只录语句）
+  测试；PG 接通后须以真实 PG 复测一次才能宣称两端可用。
+- 本模块不改 #238 auto_apply（保持 False）、不改 #247
+  （纠正为 pass 本身不解封）、不改 v1.1 契约与 7 维定义。

+would resurrect tenant-deleted auxiliary files on the next run.
+SKILL.md-only copy bounds that resurrection surface to the single
+SKILL.md file itself (auxiliary deletions are preserved trivially
+because those files never landed in the tenant home).
+(3) Seeding never prunes the tenant directory, so tenant-added
+files in a skill directory are left alone by the same rule.
+Boundary, stated plainly so it is not misread: a tenant-deleted
+SKILL.md IS re-seeded (missing = copied); only the differ-guard
+preserves edits. Preserving a SKILL.md deletion would need a
+tombstone, which is new behaviour, not a convergence fix.

+## 说明
+
+本文件新建于 2026-10-31（附录溯源一轨）。此前 SKILL.md 正文（v0.2，
+2026-10-30）已引用同目录 `CHANGELOG.md`，但包内并无此文件，因此
+v0.1 → v0.2 的 5 个 P0 缺口明细无法从本文件追溯，本文件不编造
+那段历史；以下只记录 2026-10-31 起可核实、可复查的条目。
+
+## 2026-10-31：附录溯源补齐（SKILL.md 未动，零语义改动）
+
+此前缺失：SKILL.md 称附录“由生成脚本从 `templates/roles/` 原样拼接，
+见 CHANGELOG”，但包内既无 `templates/`、也无 `CHANGELOG.md`、更无
+生成脚本，附录 9 章内容不可验——附录与源不一致时无从发现。
+
+本次补齐：
+
+- 新增 `templates/roles/` 下 9 个编辑源文件（`00-coordinator.md` 至
+  `08-shared-core.md`），内容由现行 v0.2 附录逐章机械拆出：每章源文件
+  即该章标题行之后的正文（含 00/04/07 章后的 GitHub 小节），仅剥离
+  章节标题行、章节间分隔符行与首尾空行。SKILL.md 本文件未作任何
+  改动，因此不存在语义改动；源与附录的对应关系由校验脚本钉住，
+  今后任一侧改动都会先被校验拦住，而不是悄悄漂移。
+- 新增 `tools/check_appendix.py`（仅标准库，不改 SKILL.md）：默认
+  校验模式逐章比对源与附录，源缺失、章节缺失、内容不一致、多余
+  源文件、CHANGELOG 缺失或未提及 `templates/roles/` 均以非零退出
+  失败；`--emit` 模式只把拼接后的附录规范形式打印到标准输出，供
+  编辑者起草参考，绝不是可直接覆盖 SKILL.md 的字节补丁（分隔符与
+  空行见脚本注释的允许差异清单）。
+- 新增 `cloud/tests/test_skill_appendix_provenance.py`：钉住源与附录
+  一致、源缺失即失败、脚本 `--emit` 输出与源一致。
+
+播种行为不变：`cloud/skill_seed.py` 只复制各技能的 `SKILL.md` 一个
+文件，`templates/`、`tools/`、`CHANGELOG.md` 均不进入租户目录（该行
+为已由 `test_skill_seed_pinning.py` 钉住，见其“仅复制 SKILL.md”一
+项）。因此源文件进技能包不改变租户可见内容：租户任务内仍只能
+看到 SKILL.md 随附的附录全文，附录仍是租户侧的权威版本。
+
+## 已知边界（未改行为，另起设计时再动）
+
+- 租户已删 `SKILL.md` 会在下次播种时重建（missing 即复制），这是
+  现有播种语义，不是删除保留；要保留删除需 tombstone 设计，须另
+  起一轨，不在本条目悄悄改播种行为。
+- 校验的允许差异只有三项：章节标题行本身、至多一枚章节间分隔符
+  行、标题与章末的空行。现行 SKILL.md 的分隔符并不统一（01/02/03/
+  05/06 章后有 `---`，00/04/07 章后无分隔符直接接下一章标题），校验
+  保留该现状、不强行统一 SKILL.md。
+
+## 未动项
+
+- SKILL.md 同样引用的同目录 `README.md`（装机路径）未在本条目处理，
+  仍缺失；本条目只补附录溯源，不扩大范围。
+
+## 集成基底 v0.5 附录表同步（集成仲裁，非单轨 PR 改动）
+
+- 附录章节表由 00–08（9 章）扩为 00–10（11 章）：09-ops /
+  10-iteration 源文件由 v0.5 附录章节机械拆出（与 #217 同款方法，
+  章节正文逐字取自附录 canonical 形）；09/10 章节标题的“，v0.5 新增”
+  后缀去掉，归一为 #217 严格格式（#207 的 g7g8 测试只断言标题前缀，
+  不受影响；标题后缀信息仍在附录引言“本附录同时是 v0.5 版的一部分”）。
+- 00–08 源文件同步为 v0.5 附录现状：v0.3/v0.4/v0.5 把正文改动同步进
+  附录章节后，源文件仍停在 v0.2 版，校验在 00/02/04/06/07/08 共 6 处
+  失配；方向定为源跟随附录（附录是租户侧权威版本，且任务规则禁止
+  以 v0.2 文本覆盖 v0.5），不是附录退回 v0.2。分隔符现状同步为
+  01/02/03/05/06/09 章后有 `---`。
+- 校验脚本与两份附录测试的 EXPECTED_IDS 同步扩为 11 章；#214 的
+  “仅复制 SKILL.md”结论不受影响（播种行为未改）。
+
+## #244 审计段落向 v0.5 的移植（集成时做，移植准备轨 #258 的 §1–§3 为准）
+
+- A 矩阵行：插入 QA 行之后、验收行之前（v0.5 矩阵行本身不动）。
+- B 主节：插在“失败、续跑与成本”节末、“诚实边界”节首之前；
+  引言移植警告按 R1 改写为移植注；“与已有回路的关系”按 v0.5
+  实际回路对齐（G7、全自动在本文件已有定义，注意句相应改写，
+  全自动下执行人字段口径见集成摘要：full-auto-executor +
+  installation id，签字人与执行人仍须不同）；B2、B3 全并，
+  唯收紧三末段“验收失败导致的推倒要先通知用户”整段停下
+  （全自动四类回头问用户未含此情形，须用户拍板 (a)/(b)，移植轨
+  不擅自选）；B4 QA 全链路整段停下（跨端版与 v0.5 跨视口口径正面
+  冲突，须视口版重写后再移植）；C 只插审计项，QA 项随 B4 停下。
+- D 附录章：落为 11-auditor（v0.5 已有 09-ops / 10-iteration，
+  编号顺延），标题用严格格式，源文件为

+## 2026-10-31：#244 向 v0.3 / v0.4 / v0.5 的移植准备（未移植）

+- 新增 `TRANSPLANT-PREP-244.md`：#244 新增段落（+459 行）
+  向 v0.3、v0.4、v0.5 三份文本的逐段移植 diff 准备、
+  锚点行号、合并 / 移植注 / 停下三档分级、章节号对应表、
+  templates/artifacts 二选一决策、草稿同步清单。
+  本轨不改 v0.3 / v0.4 / v0.5 文本，不声称已移植。
+- 新增 `tools/check_transplant.py`：移植检查脚本
+  （锚点检查、草稿移植、移植后检查三模式，见该文件说明）。
+- templates/artifacts 决策（本轨定为删引用，见准备文档）：
+  SKILL.md 正文 6 处 `templates/artifacts/` 引用在移植时删除
+  或改写为正文内联结构，不补模板文件进包、不改播种规则。
+  本轨不改 SKILL.md 正文，故 6 处引用在本轨包内仍在，
+  移植检查脚本的移植后检查会把残留引用报为未完成。
+
+## 已知边界（未改行为，另起设计时再动）
+
+- 租户已删 `SKILL.md` 会在下次播种时重建（missing 即复制），
+  这是现有播种语义，不是删除保留；要保留删除需 tombstone
+  设计，须另起一轨，不在本条目悄悄改播种行为。
+- 校验的允许差异只有三项：章节标题行本身、至多一枚章节间
+  分隔符行、标题与章末的空行。现行 SKILL.md 的分隔符并不
+  统一（01/02/03/05/06/08 章后有 `---`，00/04/07 章后无分隔符
+  直接接下一章标题），校验保留该现状、不强行统一 SKILL.md。
+- #244 文本里的“第 1 轨硬门禁”“第 4 轨账本”指审计加固
+  轨内部的轨号，不是本批“各项指标 9 分以上”的第 1–4 项；
+  本批第 2 项 attempts-hook、第 3 项 shell 白名单与之无关，
+  不得混淆（见准备文档）。

+# software-engineering 技能包说明
+
+本文件是源码包的导航与装机说明，不是技能规则本身。
+规则只在 `SKILL.md` 里，改规则只改 `SKILL.md`；本文件不复述
+门禁、角色细则与校验规则，复述就会漂移。
+
+版本与状态以 `SKILL.md` 文首为准：v0.2，2026-10-30，草稿；
+其文首自述未提 PR、未部署生产、未改任何生产代码。
+本文件只补说明，不改规则、不合并、不部署。
+
+## 用途
+
+面向“从零做一款软件、尤其是要同时做 web、macOS、Windows、
+iOS、Android 多个客户端”的任务：按产品规划、产品设计、架构契约、
+多客户端并行开发、联调测试、验收的顺序，用协调员任务派生角色线程
+推进，契约冻结后各客户端只在自己目录内开发，最后走评审合并与用户验收。
+
+用与不用的判定只在 `SKILL.md` 的“何时用 / 何时不用”两节，
+本文件不另立标准。只做单文件小改动、只问概念时不用本技能，
+这是 `SKILL.md` 的原话指向，不是本文件的补充规则。
+
+## 包内文件一览
+
+源码位置是 `cloud/skills/software-engineering/`，包内文件如下：
+
+- `SKILL.md`：唯一规则权威，含正文与文末附录随附版。
+- `README.md`：本文件，导航与装机说明，不进入租户。
+- `CHANGELOG.md`：变更时间线，见下文“与 CHANGELOG 的分工”。
+- `templates/roles/`：附录的 9 个编辑源，见下文“附录溯源”。
+- `tools/check_appendix.py`：附录校验脚本，只校验，不改 `SKILL.md`。
+
+## SKILL.md 章节结构（只列名，不复述规则）
+
+正文节：
+
+- 何时用 / 何时不用
+- 核心原则（协调员和所有角色线程都必须遵守）
+- 阶段 DAG（不是所有线程同时开，是按门禁、分阶段开）
+- 门禁表
+- 接单选型：协调员第一件事是问，不是写代码
+- 角色线程矩阵
+- 协调员派生子任务的必填字段
+- 待办机制（不依赖提示词注入）
+- 契约冻结与变更协议
+- 目录与分支规则
+- GitHub 保证（每线程一分支、一 PR、一合并门），下含分支、
+  PR 交付、合并门、合并方式与合并记录、发布与回滚、
+  安全六个小节
+- 测试与验收
+- 失败、续跑与成本
+- 诚实边界：原生客户端
+- 校验（协调员每过一个门禁自查一次）
+
+附录节：
+
+- 附录：角色模板（播种随附版），下含 9 章附录角色，
+  每章标题注明其来源文件，见下文“附录溯源”。
+
+## 附录溯源
+
+附录 9 章的编辑源在 `templates/roles/` 下，文件与章一一对应：
+
+`00-coordinator.md`、`01-product-manager.md`、`02-architect.md`、
+`03-designer.md`、`04-client-developer.md`、`05-backend.md`、
+`06-qa.md`、`07-acceptance.md`、`08-shared-core.md`。
+
+校验入口（仓库根目录执行）：
+
+```sh
+python3 cloud/skills/software-engineering/tools/check_appendix.py
+```
+
+该脚本默认校验模式逐章比对源与附录；`--emit` 模式只把拼接后
+的附录规范形式打印到标准输出，供编辑者起草参考，绝不是可直接
+覆盖 `SKILL.md` 的字节补丁。校验的规范形式、允许差异与失败条件
+以脚本注释为准，本文件不另抄一份；补齐的时间线见 `CHANGELOG.md`。
+任一侧改动都应先被校验拦住，而不是悄悄漂移：改附录先改源，
+再按技能轨重发附录，脚本本身不替编辑者改 `SKILL.md`。
+
+## 播种行为
+
+装机路径（`SKILL.md` 文首原话指向）：
+
+- 源码位置：`cloud/skills/software-engineering/SKILL.md`
+- 播种后租户内位置：`<codex-home>/skills/software-engineering/SKILL.md`
+
+播种实现是 `cloud/skill_seed.py`，本段只是其摘要，冲突以实现
+与测试为准：
+
+- 只复制各技能的 `SKILL.md` 一个文件；`README.md`、`CHANGELOG.md`、
+  `templates/`、`tools/` 均不进入租户目录。
+- 目标缺失则复制；目标与源码相同则不动；目标已被租户改动
+  （内容不同）则绝不覆盖，记入 `skills_skipped_differ` 并原样保留。
+- 包内某技能目录缺 `SKILL.md` 时跳过，不凭空捏造。
+- 因此租户任务内只能看到 `SKILL.md` 随附的附录全文，附录仍是
+  租户侧的权威版本；本文件与附录源只在源码包一侧可见。
+
+删除行为按现行实现写，不按设想写：租户已删 `SKILL.md` 会在
+下次播种时重建（missing 即复制）。删除保留机制见 tombstone 设计，
+行为以 skill_seed 实现为准。
+
+## 与 CHANGELOG 的分工
+
+同一说明只落一处，本文件与 `CHANGELOG.md` 不复制粘贴同一份说明：
+
+- `README.md`（本文件）：包是干什么的、文件都在哪、从哪验证、
+  播种后租户能看到什么。回答“怎么找到、怎么核对”。
+- `CHANGELOG.md`：何时补了什么、此前缺什么、缺的那段历史是否
+  可追溯。回答“这包经历了什么变化”。此前 v0.1 → v0.2 的 5 个
+  P0 缺口明细因当时无此文件而无法从本文件追溯，`CHANGELOG.md`
+  开篇已明说不编造那段历史；2026-10-31 起的附录溯源补齐条目
+  记在那里，不重复抄到本文件。
+- `SKILL.md`：规则本身，唯一权威。
+- `tools/check_appendix.py` 的注释：校验的规范形式权威。
+- `cloud/skill_seed.py` 及其测试：播种行为权威。
+
+改规则改 `SKILL.md`，改溯源记录改 `CHANGELOG.md`，改校验规则
+改脚本注释与对应测试；本文件只在导航、路径或分工本身变化时才改。
+
+## 已知边界
+
+- 本轨只补说明：不改 `SKILL.md` 正文语义，不改任何规则，
+  不改播种行为，不合并，不部署。
+- 租户已删 `SKILL.md` 会重播种，见上文“播种行为”；删除保留
+  未落地为实现，不以本文件声称已实现。
+- 附录分隔符不统一的现状与校验处理见 `CHANGELOG.md` 与脚本注释，
+  本文件不另行规定、不强行统一 `SKILL.md`。
+- `SKILL.md` 正文还提到 `templates/artifacts/` 下的模板名
+  （PRD 大纲、接单问卷、验收清单）；本包 `templates/` 目前只有
+  `roles/`，artifacts 模板不在本轨补齐范围，本文件不声称它们已存在，
+  引用状态以 `SKILL.md` 原文为准。
+- 播种落盘与 `skills/list` 发现已验证；任务内模型实际调用技能
+  尚未验证，本文件不声称已验证（见 `cloud/skill_seed.py` 的
+  honest boundary 注记）。

+|---|---|---|---|---|
+| A 矩阵行 | QA 行之后、验收行之前 | QA 行 L138 | QA 行 L206 | QA 行 L359（该行已是跨视口措辞，行本身不动） |

+
+规则语义不变性：除 B 节内的改写（§2 的 R1/R2）、
+删句（§2 的部分停下）、C/D 的编号与 §4 的引用删除外，
+移植是纯插入；目标文本已有行不得改写、不得删除
+（移植后检查的“无覆盖”子序列校验钉住这一点）。
+
+## 2. 逐段分级：合并 / 合并+移植注 / 部分停下 / 整段停下
+
+分级定义：合并 = 原文照搬；合并+移植注 = 原文照搬，
+但移植轨须在执行记录里写清注明的口径映射（不改规则）；
+部分停下 = 该段内标明的句子不移植，其余句子移植；
+整段停下 = 整段不移植，须用户或移植轨先定重写方案，
+绝不能悄悄改语义后硬搬。
+
+### 2.1 A 矩阵行：三目标全部合并
+
+行文本与 #244 L134 相同。v0.5 的 QA 行已是跨视口措辞，
+审计行插在 QA 行与验收行之间，不动运维 / 迭代两行。
+
+### 2.2 B1 审计与推回（L327–L441）
+
+- 五职分开（写 / 测 / 审 / 执行 / 签字）：
+  v0.3 合并；v0.4 / v0.5 合并+移植注——#244 写
+  “执行合并 / 发布是人或宿主操作”，在全自动模式下
+  执行人字段填主机自动执行器 `full-auto-executor` +
+  installation id（v0.4 全自动节原话），签字人与执行人
+  字段仍须不同，分离规则本身不变。
+- 硬门禁接口约定（`merge_blocked` / `release_blocked`）
+  与账本接口（`build_ledger_entry` /
+  `validate_ledger_chain`）的“目前是提案”说明：
+  三目标全部合并（提案状态未变；注意 #244 的
+  “第 1 轨 / 第 4 轨”指审计加固轨内部轨号，
+  不是本批 9 分项的第 1–4 项，不得混淆）。
+- “与已有回路的关系”段（G5 复用 + G7 并行 + 全自动并行
+  + 注意句）：
+  - v0.3 部分停下：G5 复用句移植；G7 并行句、全自动并行句、
+    注意句不移植（v0.3 文本里 G7、全自动两个回路都不存在，
+    照搬会成悬空引用）。
+  - v0.4 部分停下：G5 复用句与全自动并行句移植；G7 并行句、
+    注意句不移植（v0.4 无 G7；注意句称“全自动尚未出现”
+    在 v0.4 已为假）。
+  - v0.5 合并：G7 热修复回路（发布后应急）与全自动 CI
+    回路在 v0.5 文本里真实存在，且口径与 #244 的描述一致
+    （推回是合入前、热修复是发布后应急；计数独立）。
+- 推回上限段“与全自动 CI 自动修复限 3 次同口径”括号：
+  - v0.3 部分停下：括号改写为“推回上限独立于其它修复回路
+    的轮次预算，一方不得消耗另一方的预算”（上限 3 轮
+    本身保留；CI 轮次在审计前、推回轮次在审计后的
+    排序句随括号一并删去，v0.3 无此回路可排序）。
+  - v0.4 / v0.5 合并：v0.4 全自动节原话即“CI 自动修复
+    循环限 3 次”，口径一致；排序句（CI 轮次在审计前）
+    是 #244 的定义，v0.4 文本未另定顺序，不冲突。
+- R1 改写（三目标）：审计节引言的移植警告段
+  （“本节是按主线 v0.2 文本写的……绝不能用本文件
+  覆盖它们”）不得照搬，移植时改写为：
+  “移植注：本节源自审计加固轨，移植时已按本文件对应章节
+  的回路口径对齐。”（前文“G5 缺陷回路、合并拆分、
+  G6 用户验收的原意都不变”保留。）
+
+### 2.3 B2 推倒重做（L442–L554）
+
+- 计数口径、阈值 `> 3`、只推倒该模块、先判根因、
+  重做上限 1 次、成本与配额：三目标全部合并。
+- 状态与账本段尾句“与 G7 热修复回路并行……与全自动
+  CI 自动修复并行且计数独立”：
+  - v0.3 部分停下：尾句整体改为句号结尾（只保留
+    “与 G5 缺陷回路复用修复执行通道”）。
+  - v0.4 部分停下：删 G7 分句，保留全自动分句。
+  - v0.5 合并。
+
+### 2.4 B3 三条收紧（L555–L641）
+
+- 收紧一（第三次失败先判根因、结构性提前推倒、
+  接近完成 targeted 续轮）、收紧二（只推倒实现代码、
+  旧测试全过为第一道门）、收紧三前两条（审计兜底三件套、
+  判错纠错路径）：三目标全部合并。
+- 收紧三末段“验收失败导致的推倒要先通知用户”
+  （L635–L640，推倒前须通知并确认新方向、未确认前
+  不得静默重开）：
+  - v0.3 合并（无全自动模式，无冲突）。
+  - v0.4 / v0.5 整段停下：v0.4 全自动节称“只有四类情况
+    回头问用户”（成本超阈值、删数据 / 改权限 / 对外账号、
+    外部服务要人工验证、自动修复连续失败），验收失败触发
+    推倒前确认新方向不在四类明文之内；成本超阈值通道与
+    自动修复连续失败通道能否覆盖它，须用户拍板二选一：
+    （a）全自动四类表增加第五类“验收失败触发推倒前确认
+    新方向”；（b）该确认限定默认模式，全自动模式下走
+    已有升级通道。移植轨不得擅自选（a）或（b），
+    本轨的草稿移植已把该段排除（见 §6）。
+
+### 2.5 B4 QA 全链路（L642–L730）
+
+- v0.3 合并+移植注：
+  - 自测三项（单元 + 契约集成 + 手工冒烟）是下限，
+    不是替换：v0.3 客户端附录章的交付前自测共 4 项，
+    第 4 项“跨端一致性自查”继续有效，不得因“三项”
+    之名删掉。
+  - agent 专属六项集合与 v0.3 完全相同（单端复核 3 项：
+    沙箱越界、危险动作审批、token / 配额超限；
+    跨端 E2E 3 项：长任务超时和取消、断网续跑、
+    模型 503 重试）；v0.3 的归属拆分继续为准，
+    #244 未另定归属，不冲突。
+  - QA 分工（单端复核 + 跨端 E2E 两条线）与 v0.3
+    P1-3 的 QA 拆分是同一拆分，#244 是 elaboration，
+    不是替换。
+- v0.4 合并+移植注：同 v0.3（v0.4 继承 v0.3 的
+  QA 拆分与归属；全自动模式不改变 QA 分工）。
+- v0.5 整段停下：v0.5 已定口径把 QA 第二部分改为
+  跨视口 E2E（矩阵的行是手机 / 平板 / 桌面视口，
+  G5 门改为跨视口一致性），而 #244 QA 节至少 4 处
+  与之正面冲突：① 分工句“跨端 E2E 跑遍各端”；
+  ② G5 过关句“跨端一致性”；③ 矩阵句“覆盖全部已选
+  客户端”；④ 诚实例外句“iOS / Android 编不出来时
+  结论只能写代码评审 + Web 核心验证”（v0.5 对
+  iOS / Android 是后置占位、不进 QA 通过表；
+  Mac 句仍成立，但整节不能只拆一句硬搬）。
+  因此 v0.5 的 QA 节须由移植轨重写为视口版后再移植，
+  不得把跨端版原文搬进 v0.5。附带：QA 节内 agent
+  六项集合本身与 v0.5 一致（归属改为跨视口 E2E），
+  视口版重写时六项清单原样保留。
+- R2 改写（三目标，v0.5 的 QA 节停下故不适用）：
+  QA 节引言“QA 要求以生产 v0.2 技能为准……移植警告
+  ……技能正文 diff 全是加法”不得照搬——移植后 diff
+  本来就不是纯加法（含 R1/R2 改写、删句、§4 删引用、
+  v0.5 章节号重编），“全是加法”句在移植文本里为假。
+  改写为：“本节是独立审计与 QA 部分的补充验收标准，
+  与自动推回、推倒重做、三条收紧并列，不覆盖已有规则；
+  已有规则语义不改，只补测试机制。”
+
+### 2.6 C 校验项（L757–L766）
+
+- 审计项（三目标全部合并）：签字人独立、安全签字无条件、
+  自动推回阻塞、推倒分支处理，均为目标无关表述。
+  插入位置统一在“有一项为否”行之前（已有 v0.3 / v0.5
+  新增项之后），不拆散已有校验项。
+- QA 项：v0.3 / v0.4 合并（“每端自测三项”按 2.5 的
+  下限口径读；“跨端矩阵覆盖全部已选端”在 v0.3 / v0.4
+  仍成立）；v0.5 整段停下（“跨端矩阵覆盖全部已选端”
+  与视口矩阵冲突；“未编译端只写代码评审 + Web 核心验证”
+  与 iOS / Android 后置占位冲突；随 QA 节视口版重写
+  一并改写，不得照搬）。
+
+### 2.7 目标版本已有内容在移植后必须仍在（检查脚本钉住）
+
+- v0.3：目录隔离自动检查（命令 + 输出记入合并记录）、
+  派生校验表 8 项、子任务精简包、QA 拆分、任务间问答
+  默认策略（`docs/decisions.md` 只追加）。
+- v0.4：全自动模式（API 优先、一次授权、full-auto-executor、
+  FULL_AUTO_ENABLED、CI 自动修复限 3 次）+ 全部 v0.3 项。
+- v0.5：G7 发布后运维与观察期、G8 迭代与规模化、
+  附录 09-ops / 10-iteration、跨视口口径 + 全部 v0.4 项。
+- 绝不能用 #244 的 v0.2 文本覆盖上述任一目标文本：
+  覆盖会丢 v0.3 的目录隔离检查、v0.4 的全自动、
+  v0.5 的 G7/G8（#244 正文自己的移植警告亦如此要求）。
+
+## 3. 附录章节号对应表（不要把章节号搞混）
+
+| 线 | 附录章节 | 源文件 | 标题格式 |
+|---|---|---|---|
+| v0.2（#217） | 00–08 | `templates/roles/00-…08-*.md` | `## 附录角色：<id>（来源 templates/roles/<id>.md）`（严格式） |
+| v0.2 + #244（本轨包） | 00–08 同上 + 09-auditor | 增加 `templates/roles/09-auditor.md` | 09 标题已规范化为严格式；#244 原标题“（独立审计，新增）”不符合 #217 校验正则，移植时一律用严格式，称谓保留在章首 `# 角色模板：独立审计……` 行 |

+| v0.5 移植后 | 00–08 同上 + 09-ops + 10-iteration + 11-auditor | 增加 `templates/roles/11-auditor.md`（正文与 09-auditor 相同，只改编号与标题；另须在移植时从 v0.5 附录机械拆出 09-ops / 10-iteration 源文件，方法同 #217，否则校验脚本无法覆盖 v0.5 全表） | v0.5 现有 09/10 标题带“，v0.5 新增”后缀，不符合 #217 严格正则；移植时校验脚本的标题正则须放宽为允许可选后缀，或把 09/10 标题规范化为严格式——二选一由移植轨定，本轨不擅自改 v0.5 标题 |
+
+校验脚本期望表（`tools/check_appendix.py` 的 EXPECTED_IDS）：
+本轨包为 00–09；v0.3 / v0.4 移植后仍为 00–09；
+v0.5 移植后必须重定基为
+`00-…-08, 09-ops, 10-iteration, 11-auditor`，
+绝不能拿本轨的 00–09 表直接验 v0.5 文本。
+附录生成器（`--emit`）按期望表拼接：09-auditor 源文件缺失时
+重跑会掉 09 章；本轨补齐后 `--emit` 输出 10 章标题 + 正文。
+
+## 4. templates/artifacts 缺失模板名：二选一决策——删引用
+
+SKILL.md 正文在 6 处引用 `templates/artifacts/`，
+而 #217 后的包里 `templates/` 只有 `roles/`，没有
+`artifacts/`；`skill_seed` 只拷 SKILL.md，模板文件
+即使补进包也不会进租户目录。本轨决策：删引用
+（不补模板文件进包、不改播种规则）。取舍如下：
+
+- 为什么不选补齐：补齐为“编辑源”不能修复租户侧
+  悬空引用（租户仍看不到文件）；要真正修好须另做
+  二选一之外的事——把 5 份模板嵌进附录（SKILL.md
+  膨胀约 8KB，且 v0.3 / v0.4 / v0.5 各需一份）或改
+  播种规则（生产行为变更，另起一轨）。两种都超出
+  本轨范围，且补齐后声称“已修好”会是假话。
+- 删引用为何损失可控：6 处引用之后都紧跟内联实质，
+  删路径句不丢规则（见下表）；失去的只是现成的
+  填空式表单（工作区草稿 `templates/artifacts/` 下 5 份
+  文件仍在，仅作历史参考，不进包、不播种）。
+
+| # | 位置（6 处在三目标文本里措辞相同） | 删 / 改写 | 替代（内联实质已在正文里） |
+|---|---|---|---|
+| 1 | 门禁表 G1 行 | “PRD 按 `templates/artifacts/prd-outline.md` 写完”→“PRD 按产品经理附录章节所列大纲写完” | 产品经理附录章所列 PRD 大纲 1–6 项（含 agent 三节） |
+| 2 | 接单选型节 | 删“问卷模板在 `templates/artifacts/intake-questions.md`。”一句，保留“最关键的六问：” | 六问全文紧随其后 |
+| 3 | 测试与验收节 | 删整行“验收清单模板在 `templates/artifacts/acceptance-checklist.md`。” | 其后验收语义（用户逐项确认、按端分别做）完整保留 |
+| 4 | 产品经理附录章产出 | “按 `templates/artifacts/prd-outline.md` 写一份 PRD”→“按下面大纲写一份 PRD” | 其后大纲 1–6 项全文 |
+| 5 | 架构师附录章产出第 4 项 | “协议模板见 `templates/artifacts/` 下的 agent 任务契约模板。”→“（Agent 协议、状态机、错误 taxonomy 的要素见本章第 4、5、6 项。）” | 本章第 4/5/6 项 + G0 执行模型、权限边界、审批模型 |
+| 6 | 验收附录章协调员准备第 1 项 | “按 `templates/artifacts/acceptance-checklist.md` 生成”→“按 PRD 验收标准生成” | 其后“每一项对应 PRD 里的一条验收标准” |
+
+工作区草稿的 5 份 artifacts 文件（acceptance-checklist、
+agent-task-contract、coordinator-spawn-example、
+intake-questions、prd-outline）与本决策的关系：
+`coordinator-spawn-example.md` 从未被 SKILL.md 引用，
+其余 4 份对应上表 4 个文件名；决策后它们都不进包，
+草稿侧标注为历史参考（见 §5 同步清单）。
+
+## 5. 工作区草稿与部署版的同步清单（本轨只给清单，不执行）
+
+差异清单（实测，2026-10-31）：
+
+- 草稿 SKILL.md（40,759 字节、686 行）vs 生产部署版
+  v0.2（49,326 字节、813 行）：草稿是严格更旧的子集，
+  生产版比草稿多 7 处增补（含 G0 仓库冻结项与 G0.5
+  建仓门），另有 1 处 G0 行措辞随增补而扩展；无反向
+  增补。结论：同步方向只能是部署版 → 草稿，
+  绝不能用草稿覆盖部署版或任何 PR 文本。
+- 草稿 `templates/roles/` vs #217 源文件：01/02/03/05/06/08
+  六份逐字节一致；00/04/07 三份草稿更旧更短
+  （草稿 00: 4094 字节 vs 源 6157 字节；04: 3242 vs 4087；
+  07: 1559 vs 2121），同步时以源文件为准。
+- 草稿 CHANGELOG / README vs #217 CHANGELOG / #225 README：
+  是两套不同的文档（草稿版自述“仅起草、未提 PR”），
+  同步时以包内版本为准，草稿版不合并、不覆盖。
+- 草稿独有：`templates/artifacts/` 5 份、
+  `WALKTHROUGH-agent-tool.md`、verification/ 下各轨摘要。
+  前者按 §4 决策不进包；后两者是工作区侧资料，不进包。
+- 各 PR 文本字节数：v0.3 56,607 / v0.4 63,893 /
+  v0.5 88,540 / #244 81,565（单位：字节；行数见 §0）。
+
+合并部署后同步回草稿的步骤清单（按顺序，部署完成前不动草稿）：
+
+1. 先合 #199 → #205 → #207 链（v0.3 → v0.4 → v0.5，
+   本就是堆叠顺序），再合 #217 → #225（附录溯源 →
+   README），再合 #244 → 本轨（审计加固 → 移植准备），
+   最后由移植轨按 §1–§4 把审计段落移植进已合并的
+   v0.5 文本并解决 §2 的停下项（用户拍板后）。
+   顺序要点：移植准备轨（本轨）不得早于 #244 合并；
+   若 #217 先合并，本轨的校验脚本与 CHANGELOG
+   会冲突，解法写死为保留 00-09 版（见 §6）。
+2. 部署后，以部署版包（`cloud/skills/software-engineering/`）
+   为准覆盖草稿：SKILL.md、`templates/roles/`、
+   `tools/`、CHANGELOG.md、README.md。
+3. 草稿侧保留不动：verification/ 全部摘要、
+   `WALKTHROUGH-agent-tool.md`；`templates/artifacts/`
+   标注为“已删引用、仅历史参考”，不删除（删了会丢
+   表单原件的唯一副本），也不进包。
+4. 校验脚本（部署后在草稿目录外跑，不污染草稿）：
+   `sha256sum` 对比草稿 SKILL.md 与部署版 SKILL.md
+   必须一致；字节数与行数与部署记录一致；
+   `python3 tools/check_appendix.py` 在部署版包上通过
+   （章节数按最终合并的章节表：v0.5 线为 12 章
+   00–08 + 09-ops + 10-iteration + 11-auditor）；
+   `grep -c templates/artifacts SKILL.md` 在最终部署版
+   为 0（决策 B 落地后）。
+5. 同步后草稿 SKILL.md 文首版本行由部署轨负责更新
+   （草稿与 v0.2 部署版文首目前都自述“仍是草稿、
+   未提 PR”，该自述在部署版里已 stale，不由本轨改）。
+
+## 6. 本轨堆叠与合并顺序（PR 正文亦写清）
+
+- 本轨分支 `feat-skill-transplant-prep` 堆叠于
+  `feat-audit-pushback`（#244，`39966bd`）之上，
+  PR base 设为 `feat-audit-pushback`（不是 main），
+  以便 09 章节与源文件在真实包上可验。
+- 本轨包内改动：SKILL.md 仅 1 行标题格式规范化；
+  其余为新增文件（源文件 10 份、校验脚本 2 份、
+  CHANGELOG、本准备文档、测试 2 份）。零规则改动。
+- 合并顺序：#217 → #225 → #244 → 本轨 →
+  （移植轨，另起一轨，须用户先拍板 §2 的停下项与
+  §4 决策）→ v0.3 / v0.4 / v0.5 链的最终合并。
+  注意 #199 / #205 / #207 链与 #244 / #217 链的
+  SKILL.md 合并本身即移植动作，不在本轨完成。
+- 已知的合并冲突点（若 #217 先合并）：
+  `tools/check_appendix.py`（00-08 vs 00-09，保留 00-09）、
+  `CHANGELOG.md`（两段条目并存）、
+  `cloud/tests/test_skill_appendix_provenance.py`
+  （00-08 版 vs 00-09 版，保留 00-09）；
+  `templates/roles/00-…08-*.md` 为 identical-add，不冲突。
+- 正式移植 diff 与本轨准备 diff 的区别：本轨的
+  `check_transplant.py --apply` 输出是草稿（/tmp 内，
+  不进提交），供评审核对锚点与停下项；正式移植 diff
+  是移植轨在合并时对目标文本的真实改动，须另经
+  CI 与移植后检查（本脚本 `check-transplanted` 模式）
+  全部通过，且 §2 的停下项须先有用户拍板或重写版。
+
+## 7. 检查脚本用法
+
+```sh
+# 锚点与保留标记（对真实三目标文本已跑过，见验证摘要）
+python3 cloud/skills/software-engineering/tools/check_transplant.py anchors \
+  --source244 <244 文本> --target <v03|v04|v05 文本> --target-id v03|v04|v05
+# 草稿移植（只写 /tmp，不进提交；停下段落列在 stderr）
+python3 cloud/skills/software-engineering/tools/check_transplant.py apply \
+  --source244 <244 文本> --target <目标文本> --target-id v03|v04|v05 \
+  --out /tmp/draft-<目标>.md
+# 移植后检查（正式移植轨的门禁之一）
+python3 cloud/skills/software-engineering/tools/check_transplant.py check-transplanted \
+  --source244 <244 文本> --target <目标文本> --target-id v03|v04|v05 \
+  --transplanted <移植后文本>
+# 附录校验（本轨包内）
+python3 cloud/skills/software-engineering/tools/check_appendix.py
+```
+
+## 8. 未做项与诚实边界
+
+- 未移植：v0.3 / v0.4 / v0.5 文本在本轨零改动；
+  草稿移植输出只在 /tmp，不进提交、不进 PR。
+- 未验证：真实 PG、真实任务冒烟（按任务要求不做）；
+  本轨证据全部是本地文本比对与单测，不冒充生产验证。
+- 未做：CI 清理、台账钩子、shell 白名单、发布接线、
+  分支保护、v1.1 契约确认——均属其它轨或用户侧。
+- 用户侧仍需拍板（见验证摘要末节）：§4 删引用决策、
+  §2.4 收紧三确认段的（a）/（b）、§2.5 v0.5 QA 节
+  视口版重写方案、§3 v0.5 标题正则放宽 vs 规范化、
+  §5 同步顺序。

+# 角色模板：协调员（全程唯一，1 个线程）
+
+你是本项目的协调员。你不直接写业务代码，你负责派生、管理、评审、报门禁，
+并给出合并决定。真正的合并、PR 合并、部署由人或宿主操作执行，你不冒充执行人。
+全自动模式下（正文“全自动模式”一节）：用户只碰需求、方案选择、一次 GitHub
+授权、最后交付验收、验收失败推倒前确认，中间由主机自动执行器（`cloud/full_auto.py`，需
+FULL_AUTO_ENABLED 显式开启 + 已验证的 GitHub App installation）执行合并、
+PR、发版、回滚，你仍只给合并决定，不直接执行、不冒充执行人；执行人记为
+full-auto-executor + installation id。质量门禁全部自动且阻塞合并（CI 全绿 +
+目录隔离检查 + 契约版本 + 你的批准），门禁不过走 CI 自动修复循环，限 3 次，
+超次升级给用户。回滚只能是 revert PR 或重新部署上一 tag，绝不 force-push。
+绝不做网页自动化自动注册 GitHub 账号，不向用户索取 GitHub 密码或个人 token
+明文；一次授权后建仓、配置、分支、PR、CI、合并、发版全部走 GitHub API，
+建仓分支要诚实（组织仓可经 App token 建，用户个人仓需安装会话里先建空仓，
+记为 needs_user_once，不说成已自动建仓）。
+
+## 你必须先做的事
+
+1. 按 `software-engineering` 技能的 G0 问卷问清：目标用户、核心能力、
+   客户端清单、MVP 范围、技术路线（v0.5：web + PWA / WebView 壳，
+   iOS / Android 原生后置），以及 agent 类产品的执行模型、权限边界、
+   审批模型。六问缺一问，G0 不算过。
+   用户确认前，不派生任何开发线程。用户没回复时你等，不按假设推进。
+   已定口径（v0.5，正文“已定口径”一节同步于此）：重心是 web + React
+   + 多端自适应；默认后端是 TypeScript 全栈（Vite + React + TypeScript、
+   Fastify + TypeScript 严格模式、PostgreSQL、Drizzle 或 Prisma 二选一、
+   Vitest、OpenAPI 或共享类型），G2 冻结后不准中途换，只有用户特别要求
+   时才换语言，agent 不得以“更合适”为由换；开源优先（先查开源，查
+   许可证、维护状态、体积、安全，优先 MIT/Apache，避 SSPL / 商业重型，
+   选型记入架构）；codex-app-server 本身保持 Python，不为统一语言重写。
+2. 建待办文件 `docs/swe-todos.md`：G0 到 G8 每个阶段的任务、负责人（角色）、
+   完成定义。之后所有状态以这份待办为准，不以对话为准。
+   你是待办文件的唯一写作者，子线程只在结尾报告里写 TODO-UPDATE，
+   你核对证据后才勾选。不要虚构任何待办标记语法，不要依赖模型会自动写标记块。
+3. 每个子任务提示词必须包含：角色模板全文（来自 SKILL.md 附录）、
+   本阶段输入的版本号、拥有目录、只读目录、分支名、完成定义、
+   禁止事项、TODO-UPDATE 要求。缺一项不派生。
+   派生前校验表（必填表，填好的表原样贴进提示词，缺一项就不发任务）：
+   客户端名、拥有目录、分支名、契约版本、PRD 版本、设计版本、
+   完成定义、TODO-UPDATE 要求，共 8 项。
+   子任务精简包（裁剪规则写死）：只给本端相关的契约章节、设计页、
+   PRD 故事和冻结决策摘要（不超过 10 条），绝不把 PRD、契约、设计全文
+   复制给每个线程；提示词里必须列出精简包所含章节清单，只写“已精简”不算数；
+   线程缺章节时向你要补发，不自己猜。
+
+## 派生顺序（分阶段，默认不 5 端齐开）
+
+- G1：产品经理 1 个线程。
+- G2：架构师和 UI/UX 设计 2 个线程并行，中间加一次联合评审：
+  架构的状态机和设计的审批界面对得上才能冻结；收敛后你判定契约是否冻结，
+  冻结物必须齐：API 契约、数据模型、agent 协议、任务状态机、错误 taxonomy、
+  技术栈表、每端能力矩阵。
+- G3：共享核心 1 个线程（含 mock 服务和契约测试）；后端线程如有，
+  在 G3 阶段就参与契约测试，不要等到 G4 才对接。
+- G3.5：可行性 spike。核心链路真跑通（agent 工具就是任务能创建、能跑出进度、
+  能取消、能回结果）才能扩端，跑不通先修核心或缩 MVP。
+- G4a：web 先行 1 个线程。G4b：桌面壳 1 个线程（先 web + PWA / WebView 壳，
+  不做已编译原生应用）。G4c：v0.5 起为后置占位，不在 MVP 内派生；
+  iOS / Android 原生以后才以新端身份在 G8 接入时再开一轮 G4c。
+  用户明确签字接受并行成本和风险时，才可以在记录里写明例外原因后
+  并行开 G4a / G4b，该例外绝不把 iOS / Android 原生重新写回 MVP 交付端。
+- G5：QA 分单端复核和跨视口 E2E，安全检查点单独签字。
+  单端复核交付物是逐端复核报告（每端通过 / 不通过 + 证据 + 未复核项），
+  归单端复核的 agent 测试：沙箱越界、危险动作审批、token / 配额超限；
+  跨视口 E2E 交付物是跨端一致性矩阵（矩阵的行是手机 / 平板 / 桌面浏览器宽度：
+  同一任务、同一数据在各视口结果、文案、状态词、同步状态是否一致）
+  + 缺陷清单 + 回归清单，归跨视口 E2E 的 agent 测试：长任务超时和取消、
+  断网续跑、模型 503 重试。两部分交付物缺一不算 G5 通过。
+  （旧文“跨端 E2E 跑遍各端”自 v0.5 起改为跨视口 E2E，矩阵名保留、行改为视口。）
+- G6：你为 web 单端准备验收清单和演示产物，交用户逐项确认；
+  发布和回滚为 web 单端记录；iOS / Android 原生只留后置占位，不进本轮发布。
+- G7：运维线程 1 个（附录 09-ops），交付运维手册、问题清单、热修复记录、
+  回滚触发结论。门禁衔接 G6→G7 的条件是用户验收已确认（或不通过项
+  已列入下一轮待办并经用户确认）+ 发布记录与回滚方式齐全 + 监控 /
+  日志 / 成本口径已定，三项缺一不进 G7。
+- G8：迭代线程 1 个（附录 10-iteration），交付 v1.1 交接清单终版与
+  下一轮 G0-G6 输入冻结清单。门禁衔接 G7→G8 的条件是运维观察期结论已写
+  （问题清单、热修复记录、回滚触发是否命中）+ v1.1 交接清单齐全，
+  两项缺一不进 G8；G8 的完成不是下一版已发布，是下一轮 G0-G6 的输入
+  已冻结齐全。
+
+## 你的合并规则（评审与执行拆分）
+
+- 子线程交付物 = 分支 + 产出文件清单 + 自测命令和结果 + 已知问题 + TODO-UPDATE。
+  缺证据或缺 TODO-UPDATE 的不给合并决定，先打回补齐。
+- 合并前检查：只改了拥有目录吗（合并前由人 / 宿主跑目录检查：
+  `git diff --name-only $(git merge-base origin/main HEAD)...HEAD`，
+  逐项核对是否落在拥有目录内，契约变更经批准的除外；检查命令与输出
+  文件清单必须原样记入合并记录，缺检查输出不给合并决定）？
+  契约是冻结版本吗？CI 通过吗？有没有把“未验证”写成“已完成”？
+  有一项不过就不给合并决定。
+- 你的决定写成合并记录：哪个分支、谁评审、CI 结果、执行人是谁
+  （默认模式执行人是人或宿主操作；全自动模式执行人是主机自动执行器
+  full-auto-executor + installation id，不是你、不是任务 agent）。
+  冲突由你判定，不让子线程自行解决后静默推主线。
+
+## 契约变更处理
+
+收到契约变更请求后，你要写清批准或不批准及理由。批准的：
+契约版本号加一，通知所有受影响客户端线程做回归；不批准的：
+提议线程按旧契约做，差异记入已知问题。
+
+## 任务间问答与决策记录（协调员）
+
+- 被问题卡住的线程先按冻结契约做，把假设写成开放问题记入结尾报告，
+  不无限等你答复、不停工等；你在下一轮答复（确认、纠正并发回归任务、
+  或升级为契约变更），答复记入决策记录。
+- 决策记录落盘 `docs/decisions.md`，由你维护，只追加不改写历史；
+  一条决策写清日期、议题、决定、理由、影响端；推翻旧决策追加新条
+  写明“取代 D-n”，绝不改旧条原文、不删旧条。
+
+## 跨任务产物传递（协调员）
+
+- 回归任务拿不到核心代码时，绝不让回归自己写 fixture 猜契约：
+  走技能正文“跨任务产物传递”一节。
+- 清理核心租户前先取出核心产物（代码、测试、产物清单
+  `artifacts/ARTIFACT_MANIFEST.json`），
+  独立重算 sha256，与核心报告、清单文件三方核对，全对上才传。
+- 派生回归时双通道给齐：提示词里贴已核验产物清单全文，
+  再贴核心文件完整原文，令回归先原样写盘、算 hash、对不上就停。
+- 回归结尾没有 ARTIFACT-VERIFY 一节、没有 ARTIFACT-VERIFY-OK，
+  或报了 ARTIFACT-HASH-MISMATCH，结论一律不接受，重新传递或重跑核心。
+- 核心修完缺陷出新产物时，旧核验作废，按新清单重新走三方核对
+  与双通道核对，不得沿用旧 hash。
+
+## 失败处理
+
+- 有进度的中断任务：断点续跑。
+- 从未开始的任务：全新重跑，不直接判死。
+- 单个客户端失败：只重开它，不重开全部。
+
+## 你的交付物
+
+每个门禁一份简短判定：过了哪个门、证据是什么、下一阶段派生哪几个线程、
+有什么风险和未完成项。G6 的交付物是用户确认过的验收清单，不是你自己勾的清单。
+G7 的交付物是运维手册与观察期结论（含热修复记录、回滚触发是否命中）；
+G8 的交付物是 v1.1 交接清单终版与下一轮 G0-G6 输入冻结清单，不是下一版发布证明。
+
+---
+
+
+## GitHub 保证（协调员）
+
+- 建仓：G0 之后、G1 之前做。新产品建仓和首 commit 是前置任务，
+  首 commit 只含仓库骨架，不含业务代码；已有仓库先核对 owner/repo、
+  默认分支、可见性与 PRD 一致。仓库冻结项（新建还是已有、owner/repo、
+  默认分支、可见性）缺一项，G0 不算过。
+- 分支：每线程一分支，命名 feat/swe/<阶段>-<角色>-<简称>；
+  绝不直接推默认分支，绝不对默认分支 force-push；落后主线先同步主线
+  再提 PR，冲突由你判定，不静默解决后推。
+- PR 交付：没有 PR 号不算完成。PR 正文必须有范围、契约版本、
+  测试证据、已知问题、关联待办或 PRD 项；评审意见逐条处理，
+  未解决的评审意见不能合并。
+- 合并门：GitHub Checks 全绿、目录归属检查通过、契约版本是冻结版、
+  你评审通过、无未解决评审意见，五项缺一不可。
+  CI 用只读方式查，例如 GET /tasks/{id}/pr/checks，它绝不重跑检查、
+  不批准、不合并；无 PR 时它会 409，先补 PR。
+- 主分支保护：要求 PR、要求 CI 通过、禁止直接推，这是 GitHub 仓库设置，
+  不是本平台代码能替你开的。没开保护时记为风险并去开通，不假装已保护。
+- 合并门禁：同正文，代码在 cloud/merge_gate.py 与
+  cloud/merge_gate_hard.py，模式由 CLOUD_MERGE_GATE_MODE 控制，
+  默认 hard：五项全查、缺一 409、状态不变、写 merge_gate_blocked
+  审计，无证据不放行，unknown 不等于 protected，未保护即使带
+  显式确认也不放行；record / enforce / off 须显式设置才生效，
+  record 下未保护时须显式确认才放行。显式确认只覆盖保护风险，
+  绝不覆盖目录隔离违规；目录检查复用 v0.3 的 git diff --name-only
+  口径；技能播种仍只复制 SKILL.md，不做整目录复制。
+- 合并记录：默认 merge commit；记录必须含 PR 号、合并提交 hash、
+  CI 运行链接、执行人（人或宿主操作，不是你自己合）；
+  合并后删远程分支，删前确认合并提交已在主线。
+- 发布与回滚：按端打 tag，例如 v0.1.0，发布说明从已合 PR 汇总；
+  回滚是 revert 对应 PR 或重部署上一个 tag，绝不是 force-push 回退。
+- 安全：密钥、口令、token 绝不进代码、commit、命令行、PR 正文、日志；
+  token 只进子进程环境（cloud/pr.py 的做法：只进子进程环境变量 GIT_TOKEN，
+  不进命令行参数、不进远端 URL）；新仓库首 commit 前检查 .gitignore
+  覆盖密钥文件与本地配置文件。

+## 输入
+
+协调员给你的：冻结或待冻结的 PRD、客户端清单、技术路线、
+执行模型、权限边界、审批模型。设计线程会和你做一次联合评审，
+状态机和审批界面对得上才能冻结。
+
+## 只能写
+
+冻结前：`contracts/`、`packages/shared/`、`docs/architecture.md`。
+冻结后：没有协调员批准的契约变更，一律不改 `contracts/`。
+
+## 产出
+
+1. 仓库布局：按技能主文档的单仓布局，删掉未选客户端的 `apps/*`，写清每个目录归谁。
+2. API 契约：接口、请求 / 响应、错误码、鉴权方式、分页与同步规则，版本号从 v1 开始。
+3. 数据模型：核心实体、字段、关系、同步冲突时以哪端为准。
+4. Agent 协议：如果产品含 agent 能力，写清任务创建、执行、状态、取消、
+   超时、失败重试的协议，不要让各客户端自己发明一套。
+   （Agent 协议、状态机、错误 taxonomy 的要素见本章第 4、5、6 项。）
+5. 任务状态机：至少包含创建、排队、运行中、等审批、已完成、已取消、失败、超时，
+   每个状态的进入条件、退出条件、可执行操作都要写清。
+6. 错误 taxonomy：至少区分模型失败、工具失败、用户取消、超时、权限拒绝、配额超限，
+   每个错误给固定错误码和各端统一提示文案，同一错误在各端不得换名字。
+7. 技术栈表：每端用什么栈、共享核心用什么语言、壳用什么方案，冻结后不擅自换栈。
+   v0.5 默认栈（正文“已定口径”同步于此）：前端 Vite + React + TypeScript、
+   后端 Fastify + TypeScript 严格模式、PostgreSQL、Drizzle 或 Prisma 二选一、
+   测试 Vitest、API 用 OpenAPI 或共享类型；G2 冻结后不准中途换，只有
+   用户特别要求时才换语言，agent 不得以“更合适”为由换。
+   开源优先：每个模块先查开源（许可证、维护状态、体积、安全），优先
+   MIT/Apache，避 SSPL / 商业重型，选型记入技术栈表或决策记录。
+   边界：codex-app-server 本身保持 Python，不为统一语言重写；上面
+   的 TypeScript 默认栈只适用于本技能新做的产品。
+8. 每端能力矩阵：后台执行、通知、文件权限等能力在每端是否提供、受什么限制，
+   做不到的端写明降级方案，不写“全端一致”蒙过去；v0.5 默认矩阵只有
+   web 视口（手机 / 平板 / 桌面），iOS / Android 原生后置占位，不列为已提供端。
+9. 跨端一致性规则：同一数据、同一任务在各端应该表现一致的地方列出来，
+   差异处要说明是刻意差异还是待统一；v0.5 下“各端”首先指跨视口
+   （手机 / 平板 / 桌面浏览器宽度），规则是同一任务、同一数据在各视口
+   结果、文案、状态词、同步状态是否一致。
+10. 共享核心分层：共享逻辑（状态机、事件解析、重试策略）归共享核心线程；
+    各端适配器（token 存法、通知、文件权限）归各客户端线程，不要混成一层。

+## 各端要点（按你的客户端只看对应一条）
+
+- **web**：优先可安装的 Web 应用（PWA），启动、登录、核心 agent 任务、
+  离线或弱网提示都要覆盖。交付物是可部署的 Web 产物加部署说明。
+- **macOS**：先按 G0 定好的路线做。Web 核心 + 壳的路线：壳代码
+  （窗口、菜单、登录态、与 Web 核心的通信）要完整；真原生路线：
+  按目标机器的构建步骤交付。没有 Mac 编译环境时，明确标注未验证。
+- **Windows**：同 macOS，路线以 G0 为准。安装包、窗口行为、系统托盘
+  等如在 MVP 内要实现，如不在要写进已知问题，不假装有。
+- **iOS**（v0.5 后置占位，iOS/Android 后置）：不在 MVP 内，不派生本端
+  开发线程；只留后置占位说明（以后才接入、接入条件待 G8 新端接入时
+  再定），并标注“未编译 / 未验证、未发布”。旧的“Web 核心 + iOS 壳代码
+  + 在 Mac 上的构建步骤”写法自 v0.5 起废止，不得再把 iOS 写成 MVP 交付端。
+- **Android**（v0.5 后置占位，iOS/Android 后置）：同 iOS，不在 MVP 内；
+  只留后置占位说明，并标注“未编译 / 未验证、未发布”。旧的
+  “Web 核心 + Android 壳代码 + 构建步骤”写法自 v0.5 起废止。
+
+## 交付前自测（缺一项不算完成）
+
+1. 单元测试通过，写清跑了什么命令、结果是什么。
+2. 对接契约的集成测试通过（可用 mock 服务端，但要说明 mock 覆盖了哪些接口）。

+- 分支名、改动文件清单（只在拥有目录内）。
+- 自测命令和结果、冒烟清单结果。
+- 已知问题清单：哪些没做、哪些没验证、哪些是刻意和别的端不一致。
+- 给 QA 的说明：怎么启动你的客户端、测哪个核心流程、哪里最容易出问题。
+- 结尾必须带 TODO-UPDATE 小节，格式见技能主文档“待办机制”：
+  完成项要附证据，未完成项要写原因，新增项要写归属。缺这节视为交付不完整。
+
+## 禁止
+
+- 不改契约、不改他人目录、不复制共享代码到自己目录里再各改各的。
+- 不把“代码写完了”写成“应用已发布 / 已上架”；没编出来的包、没上架的
+  应用，一律写“未编译验证 / 未上架”，并写清在目标机器上验证的步骤。
+- 不编造测试结果。没跑过的测试写没跑过，不要写通过。

+  格式 feat/swe/<阶段>-<角色>-<简称>；绝不直接推默认分支，
+  绝不对默认分支 force-push；落后主线先按协调员写清的方式同步主线再提 PR。
+- 交付必须含 PR 号：推分支、建 PR，正文写清范围（你的拥有目录）、
+  契约版本、测试证据、已知问题、关联待办或 PRD 项。没有 PR 号不算完成。
+- 合并门由协调员判定：Checks 全绿、目录归属通过、契约版本是冻结版、
+  评审通过且无未解决意见；你不自己合并、不绕过评审推主线。
+- 合并门禁：同正文，模式由 CLOUD_MERGE_GATE_MODE 控制，默认
+  hard：五项全查、缺一 409、状态不变、写 merge_gate_blocked 审计，
+  无证据不放行，unknown 不等于 protected，未保护即使带显式确认
+  也不放行；record 须显式设置才生效，未保护时须显式确认才放行；
+  显式确认只覆盖保护风险，绝不覆盖目录隔离违规；目录检查复用
+  v0.3 的 git diff --name-only 口径；技能播种仍只复制 SKILL.md，
+  不做整目录复制。

+   归跨视口 E2E（同一任务跨视口行为一致）：长任务超时和取消、断网续跑、模型 503 重试。
+4. 安全检查点（G5 单独签字）：权限边界是否按契约实现、密钥是否外泄、
+   agent 是否能读工作目录外文件。安全检查不算 QA 的附带项。
+5. 缺陷清单：每个缺陷写清复现步骤、影响客户端、严重程度、归属线程。
+6. 回归清单：契约从 v1 升到 v2 时，哪些用例必须重跑；G5 缺陷修完回 G5 回归，
+   回归范围按契约变更影响面定，不是每次都全量重测。

+# 角色模板：独立审计（1 个线程，与 QA、协调员、执行人分开）
+
+你是本项目的独立审计线程。你不写业务代码、不改待办、不给合并决定、
+不执行合并。你只做：独立重跑测试、抽查证据、单独签字。
+
+## 你必须先做的事
+
+1. 拿到交付物后自己重跑测试，不要只复读 QA 的报告；QA 说通过
+   不等于你通过，你的重跑命令和结果要写进审计记录。
+2. 按技能主文档“独立审计与自动推回”一节逐项核对：CI、目录隔离、
+   合同版本、协调员批准、未解决评审意见、安全签字、回归确切产物、
+   演示可运行、已知偏差到期跟进 todo。缺一项证据即 fail，不补猜。
+3. 签字人就是你，且必须与任务执行人、协调员批准人、QA 测试人
+   都不同；相同即审计结论无效，按 fail 处理。
+
+## 你的签字规则
+
+- 只有无条件通过，或拦住。CONDITIONAL 不算通过；安全签字
+  CONDITIONAL 时结论就是 fail，并触发自动推回。
+- 已知偏差无到期跟进 todo、或到期未跟进时，结论就是 fail。
+- 回归用了 fixture 替身、或 hash 对不上时，结论就是 fail，
+  fixture 项单独列“未实测”，不写成通过。
+- 演示没跑应用入口（例如只起了通用文件服务器）时，结论就是 fail。
+
+## 你的交付物
+
+- 审计结论原文、失败项逐条（测试名、文件路径、行号、合同条款、
+  diff 范围）、复现步骤、上一轮产物清单与哈希。
+- 审计 fail 时你不等人点头：系统按“自动推回”一节自动派生修复
+  子任务并阻塞合并/发布；你只负责把推回包写完整。
+- 模块失败超过 3 次时，你先判根因（见“推倒重做”一节的两轮标准），
+  再决定是推倒重做还是转 G2 重新冻结升级；根因判定结果写进审计记录。
+
+## 禁止
+
+- 不替开发线程改代码“顺手修掉”，修了就审不出原缺陷。
+- 不把“没测”写成“通过”，不把 CONDITIONAL 写成通过。

+"""Verify the software-engineering skill appendix against its sources.
+
+Provenance (see CHANGELOG.md in the skill directory): SKILL.md claims
+its appendix is "spliced verbatim from templates/roles/ by a generation
+script". The sources live at templates/roles/<id>.md next to SKILL.md;
+this script is the check that makes that claim testable. It never edits
+SKILL.md: the fix for a mismatch is an editorial decision (edit the
+source, then re-issue the appendix through the skill's own track),
+never a silent rewrite by this script.
+
+What it checks, in order:
+  1. SKILL.md contains the appendix intro and exactly the twelve
+     chapters 00..11, in order, each with a source note naming its own
+     templates/roles/<id>.md file.
+  2. templates/roles/ contains exactly those twelve source files:
+     a missing source fails, an unexpected extra file fails.
+  3. Each source, in canonical form, equals the matching appendix
+     chapter in canonical form (see canonical() below).
+  4. CHANGELOG.md exists in the skill directory and mentions
+     templates/roles/, so the "see CHANGELOG" pointer in SKILL.md
+     resolves to a provenance record, not a dangling reference.
+
+Canonical form (the ONLY allowed differences between a source file
+and its appendix chapter -- anything else is a failure):
+  a. The chapter heading line itself ("## 附录角色：<id>（来源
+     templates/roles/<id>.md）") exists only in SKILL.md; it is
+     derived from the file name, not stored in the source.
+  b. One inter-chapter separator line "---": in the current SKILL.md
+     it appears after chapters 01/02/03/05/06/09 only. Chapters
+     00/04/07 end with their GitHub subsection and run straight into
+     the next heading with no separator, and 11-auditor is the end
+     of file.
+     The check strips at most one trailing separator; it does NOT
+     normalise SKILL.md to a uniform separator, so the current
+     inconsistency stays visible and untouched.
+  c. Blank lines around the heading and at the chapter end: a source
+     file is stored with exactly one trailing newline and no leading
+     blank line; the check strips surrounding blank lines before
+     comparing.
+Any other difference -- wording, punctuation, order, a dropped or
+added line -- fails with the first differing line number.
+
+Usage:
+  python3 tools/check_appendix.py [--skill-dir DIR]
+  python3 tools/check_appendix.py --emit [--skill-dir DIR]
+
+--emit prints the spliced appendix in canonical form (heading line +
+source body per chapter) to stdout. It is a drafting aid for an
+editor, NOT a byte patch for SKILL.md: because of (b) and (c) above,
+its output differs from SKILL.md in separators and blank lines only,
+and it must never be pasted over SKILL.md without a review pass.
+
+Exit codes: 0 = all chapters match; 1 = any check failed; 2 = usage
+error (argparse). Only the standard library is used, so the script
+runs standalone without importing cloud/.

+                      the transplant needs, and that every rule the

+                      are NOT applied and are listed on stderr.

+- Parse unification: agent_tools / tool_approvals column parsing
+  lives only in agent_def.py; server keeps None (undeclared),
+  worker maps None to [] / {} at the _task_from_row boundary.
+- Goal branch of _apply_resume_preamble is reachable (via
+  _goal_convert_queued on a queued auto-resumed task), so it is
+  kept and tested, not deleted as dead code.
+- Fail-open inventory: audit write failure and preamble lookup
+  failure log a warning without breaking dispatch.
+- M7: shadow endpoint explicit_capability_failures_truncated flag.
+- Policy content fingerprint: stable for the same document,
+  changes when requires change, never touches audit rows.
