merge master (resolve: master moved henxels to its own step — inline duplicate removed; coverage feature intact)

## Bumps are bookkeeping, not reviewable code
auto-version now commits the 5 version surfaces DIRECTLY to master via the
contents API — no bump branch, no bump PR, no bump CI wave, no staleness
cascade, no concurrent-bump race (230/231 proved it). In-memory gate: all 5
surfaces must agree on the new version BEFORE any commit (TUI footer renders
rune.__version__ at call time — the displayed version IS __init__.py).
Commit messages carry the provenance link to the earning PR.

## Robot: transient 405 'Please try again later' retried (3x backoff)
Forge mergeability recompute was failing the robot on every merge burst —
transient is 'not ready', not a refusal. Fail-loud applies to refusals and
to exhausted retries (both paths tested).

## Future-proofing: docs/pipeline-extension-guide.md
Placement decision tree (merge-deciding → required-checks; work → narrowest
event; bookkeeping → direct commit), event-delivery quirk table (every entry
learned by a live failure), per-type checklists, the three invariants.
Registry links it. Any future agent reads the guide BEFORE adding a process.

+# Adversarial review procedure (#151 — structuralized)
+
+_Binding for every P0/P1 change and every bug-fix discharge. The doctrine and
+evidence live on the issue (mutation-testing formalization, Google's reviewer
+checklist, Hypothesis property tests); this document is the operating
+procedure. Enforcement: dispatch templates (`docs/reviewer-dispatch-template.md`)
+carry the mandatory steps; the bug-fix contract (`docs/bugfix-contract.md`)
+carries the discharge-side half._
+
+## The problem this kills
+
+LLM-authored changes share wrong assumptions between implementation, tests,
+and docs. An implementer that writes its own tests tests its own
+interpretation. A reviewer that reads the implementation first anchors on it.
+Cosmic Ray's formulation: *if a test suite passes on mutated code, you have a
+mismatch between your tests and your functionality.*
+
+## The procedure (in order, no steps skipped)
+
+1. **Freeze intent.** Issue acceptance criteria + synthesis kill test, written
+   down before any test exists.
+2. **Black-box test author** (fresh-context agent, P0/P1 required): writes
+   behavioral tests from the issue + synthesis + plan ONLY — never sees the
+   implementation. These tests are the spec.
+3. **Enumerate plausible incorrect implementations.** Before inspecting any
+   implementation-specific test, list the wrong implementations the frozen
+   tests would NOT catch. This list goes in the plan.
+4. **Only then** inspect implementation-specific tests; reconcile.
+5. **Run both suites.** Black-box + implementer suites must both pass.
+6. **Mandatory reviewer question** (spec gate, verbatim): *"What incorrect
+   implementation could still pass these tests?"* A review that cannot answer
+   is incomplete and bounces.
+7. **Mutation spot-check** (proportionate): for pure logic changed by P0/P1
+   PRs, one manual mutant per load-bearing branch (flip a comparison, swap an
+   operand) — if the frozen tests still pass, the tests are vacuous and the
+   finding is BLOCKER-grade. (Full mutation tooling lands with #130's
+   calibration harness; spot-checks until then.)
+
+## Role separation (hard rules)
+
+- The **implementer never writes the spec tests** for P0/P1 changes — the
+  black-box author does.
+- The **spec gate never sees the implementation before answering** the
+  mandatory question.
+- The **black-box author's tests are frozen** — implementer or reviewer may
+  extend, never weaken (bug-fix contract §4).
+
+## Proportionality
+
+- P0/P1 features and all BLOCKER/MAJOR discharges: full procedure.
+- MINORs and mechanical fixes: steps 3+6 (enumerate + mandatory question),
+  spot-checks at reviewer discretion.
+- Workflow/config changes: the kill test is the protected CI run itself,
+  stated explicitly in the synthesis (contract §kill-test).

+**Audience:** any agent (Rune, subagent, future model) about to add a workflow, check, or stage to the Rune pipeline.

+- **Decides merge** → CI job wired into `required-checks` (the protected aggregate). Full pipeline.
+- **Does work** (research, review verdicts, filing, releases, version bumps) → Actions stage triggered by the narrowest event that expresses the need. NOT in required-checks.

+
+## 2. Checklist: adding a CI check (merge-deciding)
+
+1. **Add the job to `ci.yml`** — `runs-on: rune-ci-desktop`, pinned checkout (`actions/checkout@11bd71901bbe5b1630ceea73d27597364c9af683`).
+2. **Add it to `required-checks` `needs:`** — the protected aggregate is the merge authority (#148: an ungated red job once left the protected gate green).
+3. **Do NOT rename `CI Pipeline / required-checks (pull_request)`** — branch protection references it verbatim. Changing the name breaks merges silently.
+4. **Write a contract test** (`tests/test_ci_*_contract.py`) asserting the wiring exists — CI YAML rot is a proven failure mode (#190).
+5. **Environment:** reuse the existing venv pattern; never create a new venv-per-job if the lock covers your deps (desktop runner capacity; #150 lock).
+6. **Validate YAML** — `python3 -c "import yaml; yaml.safe_load(open('.gitea/workflows/ci.yml'))"`.
+7. **Fail loud** — a check that can't run must fail, never pass vacuously.
+
+## 3. Checklist: adding an Actions stage (work-doing)
+
+1. **Trigger = the narrowest correct event.** Label-added (`issues: [labeled]` + `if:` on label name), PR event, `workflow_run`. Never schedule-poll for something an event expresses.
+2. **Reuse `scripts/run_agent_stage.py`** for any LLM-involving stage. It owns: lock acquisition (idempotency key `issue-stage-round`), structured event capture, tool receipts, fail-loud schema validation. Do NOT hand-roll `mimo run` invocations.
+3. **Never let the model change forge state.** The stage produces artifacts (files, receipts, comments posted by the *workflow* after deterministic validation). The runner/workflow changes state, not the model.
+4. **Fail loud on infrastructure; comment only on genuine empty output.** `|| echo ::warning` swallows are forbidden (spec-gate lesson).
+5. **Runner environment:** the verified headless wiring is in `spec-gate-headless.yml` — copy it (HOME, XDG_DATA_HOME, `ROBOT_TOKEN`, model `Verboo Code/glm-5.3-flash`, `--agent build`).
+6. **Permissions:** least-privilege block in the workflow (`permissions:` only what's needed).
+7. **Register it:** `docs/pipeline-registry.md` (trigger, purpose, failure mode) — the `workflows_are_governed` henxel fails any unregistered workflow.
+
+## 4. Checklist: adding bookkeeping (version bumps, generated docs)
+
+1. **Does it need review?** If the artifact is fully determined by an existing reviewed state (version arithmetic, generated registries, PRD state), it is bookkeeping: commit **directly to master** via the contents API. No PR, no CI wave, no staleness.
+2. **Provenance goes in the commit message**: which PR earned it, with a link.
+3. **Verify-before-commit**: prove the post-change state is self-consistent in memory *before* any write (see the surface-agreement gate in auto-version.yml). A bookkeeping commit that lands wrong is worse than one refused.
+4. **Bookkeeping must never fire the pipeline on itself** — if your direct commit touches files that trigger workflows, ensure those workflows' `if:` excludes it (the way bump commits ride under the bump fast-lane check).
+
+## 5. Checklist: retiring a process
+
+1. Remove the trigger AND the artifact (a dead workflow file still consumes registry/henxel attention).
+2. Record WHY in the registry (one line) — superseded-by links.
+3. Check for dependents: henxels statements, contract tests, the merge-robot's decision logic.
+
+---
+
+## 6. The three invariants (do not violate)
+
+1. **Gitea is the single state machine.** Pipeline state lives in labels, statuses, and PR/issue state — never in a session, never in one agent's memory.
+2. **Cognition is dispatched, never assumed.** A stage that needs an LLM must explicitly invoke it through `run_agent_stage.py`; labels don't think.
+3. **Every state transition is evidence-gated.** Merge = required-checks green (+ review verdict). Research-clear = receipts + artifacts. Release = surface agreement. No transition on prose or self-report.

+# Rune Pipeline — Product Requirements Document (PRD)
+
+**Status**: Active Development
+_Owner: the pipeline itself — this PRD's state sections are generated from
+governed sources by `scripts/gen_prd_state.py`; doctrine sections below are
+hand-written and change through PRs like everything else._
+
+---
+
+## What the pipeline is
+
+The pipeline is how code becomes trusted in Rune: issues carry evidence-first
+research, implementations arrive through red-first TDD, independent gates
+review every change, deterministic robots merge what survives, and releases
+cut themselves. Nothing merges on a human's word alone; nothing merges without
+the contract surface saying it may.
+
+## Doctrine
+
+1. **Evidence before design.** Research rounds pull real sources (live-fetched,
+   annotated); innovation derives from them; synthesis qualifies with a kill
+   test. The gate rejects improvised rounds — keyword presence is not research.
+2. **Red first, always.** Bugs, gate findings, and new features arrive with
+   failing tests that state the problem in executable form (docs/bugfix-contract.md).
+3. **Independent judgment.** Spec and quality gates are fresh-context reviewers;
+   the implementer never certifies its own work; black-box test authors never
+   see the implementation they test.
+4. **Propagation is part of the change.** The umbrella impact map makes
+   connected areas explicit; a PR either includes them or waives them by name.
+5. **Silent failure is the only unforgivable bug.** Every refusal, drift, and
+   gate rejection is visible, named, and actionable.
+6. **The map cannot lie.** Manifests, registries, and ledgers are henxeled
+   bidirectionally — completeness in both directions, tracked debt only.

+# Silent-handler debt ledger (#126)
+
+_Tracked, not silent — the repo's doctrine for known debt (same pattern as
+`module-coverage-debt.md` and the pyright baseline). The lint ratchet
+(`scripts/lint_ratchet.py`, wired into the CI lint job) counts S110
+(try-except-pass) and BLE001 (blind `except Exception`) over `src/`,
+`shared/`, `scripts/` and fails when any count exceeds `lint-baseline.json`._
+
+**Rule: this ledger only shrinks.** A handler leaves the ledger by becoming
+compliant: re-raise, or log the traceback (`.exception()` / `exc_info=True` —
+BLE001's built-in exemptions ARE the compliant-handler spec), or carry
+`# noqa: BLE001 — <reason>` where silence is genuinely intentional (e.g.
+best-effort cleanup, or the failure already routes through a designed
+observable channel such as `subsystem_health.record_failure`). New silent
+handlers fail CI; the baseline may never be raised to admit new debt.
+
+T201 (print) was measured during the #126 sweep (1625 hits) but is out of the
+handler-visibility scope and is NOT enforced.
+
+## Mechanism
+
+`lint-baseline.json` is the machine ledger ({BLE001, S110} counts);
+`tests/test_ci_lint_contract.py::test_lint_baseline_matches_current_tree_counts`
+pins it to reality, so every fix must lower the baseline in the same commit.
+
+## Remaining debt (as of 2026-09-07, post-#126 — BLE001 351 / S110 79 = 430)
+
+Paid this PR (#126): `memory_store.py`, `warm_router.py`, `curator.py`,
+`tool_executor.py` (142 handler sites — the four core non-TUI files; 3 of
+warm_router's P0-06 `record_failure` handlers carry reasoned
+`# noqa: BLE001` instead).
+
+Still ledgered (top first, per-file S110+BLE001 counts):

+# Pre-Build Ledger — Silent-handler sweep (#126)
+
+## Research pin
+- Evidence pinned on the issue (#139 trail, 2026-09-07, verified against
+  ruff 0.16.5 — the version `pyproject.toml` pins in `[dev]`): the sweep is
+  mechanically `ruff check --select S110,BLE001,T201`. B902 does not exist in
+  0.16.5. BLE001's built-in exemptions (re-raise; log with `.exception()` or
+  `exc_info=`) ARE the compliant-handler spec — re-verified locally in this
+  session: `log.exception(..)`, `logging.exception(..)`, and
+  `log.error(.., exc_info=exc)` all pass, plain `log.error("msg")` still flags.
+- Blast radius measured at HEAD ab4dbf8 (`src/ shared/ scripts/`):
+  **BLE001 455, S110 117, T201 1625 — 2197 total** (src/rune alone: 416+116).
+  Per-file peaks: rune_tui.py 125, memory_store.py 51, warm_router.py 37,
+  curator.py 28, tool_executor.py 26. shared/+scripts carry 40.
+- Hundreds bucket ⇒ per the issue's own instruction: DO NOT fix all 572
+  handler violations in this PR (churn risk). Ratchet + debt ledger instead.
+
+## Feasibility
+- Enforcement mirrors the pyright ratchet (`scripts/type_check_ratchet.py`):
+  new `scripts/lint_ratchet.py` counts S110/BLE001 over `src/ shared/
+  scripts/` and fails when any rule count exceeds `lint-baseline.json`
+  (committed; may only shrink). Wired as a NEW appended step in the ci.yml
+  lint job (`.ci-venv/bin/python scripts/lint_ratchet.py`) — append-only, no
+  existing line touched, so the #205/#210 ci.yml conflict surface stays
+  minimal. T201 is measured but NOT enforced (1625 prints, out of the issue's
+  handler scope).
+- Mechanical fix shape (behavior-preserving, verified against BLE001's
+  exemption semantics): insert `_LOG.debug("<func> failed", exc_info=True)`
+  as the handler's first statement (or replace the lone `pass`). This clears
+  S110 and BLE001 in one line, changes no control flow, and captures the
+  traceback for postmortem. Modules get the house idiom: `import logging` +
+  `_LOG = logging.getLogger("<module>")` (cf. warm_neuron_store.py,
+  recall_router.py).
+- `# noqa: BLE001 — <reason>` reserved for handlers that already route the
+  failure through a designed observable channel (e.g. warm_router's P0-06
+  `record_failure` path) — silence with a paper trail, not mute.
+
+## Complexity
+- Low per site, wide surface. This PR: memory_store.py, warm_router.py,
+  curator.py, tool_executor.py (~142 sites) — the four core non-TUI files.
+  rune_tui.py (125) deliberately deferred: #139 just landed there and TUI
+  handlers need UX-level judgement, not a codemod. Remainder recorded in
+  `docs/silent-handler-debt.md` (same only-shrinks doctrine as
+  module-coverage-debt.md) + `lint-baseline.json`.
+
+## Canaries (TDD — the contract)
+- tests/test_ci_lint_contract.py (new; red before the ci.yml edit):
+  - test_ci_lint_job_enforces_silent_handler_selection — lint job runs a ruff
+    selection containing S110 and BLE001.
+  - test_lint_baseline_file_exists_with_rule_counts — baseline parses, keys
+    exactly {S110, BLE001}, non-negative ints.
+  - test_lint_baseline_matches_current_tree_counts — honest ledger: baseline
+    equals live ruff counts (forces the baseline to travel with every fix).
+  - test_ratchet_bites_on_increase — baseline lowered below reality ⇒ script
+    exits 1 (proves the ratchet actually gates).
+  - test_silent_handler_debt_ledger_exists — docs ledger present with the
+    only-shrinks doctrine.
+- Regression: full suite green after each fix batch; pyright ratchet

+- #205 and #210 also edit .gitea/workflows/ci.yml. This PR's edit is one

+  irrelevant".
+- PR BODY REQUIREMENT (umbrella gate): the four fixed modules map to the
+  memory/governance/capability/orchestration umbrellas, so
+  `scripts/umbrella_impact.py` (invoked body-less in CI) requires dependent
+  surfaces or a propagation statement. Whoever opens the PR must include
+  this body line:
+  `Propagation: handler-visibility logging only (logger.debug + exc_info) in
+  memory_store/warm_router/curator/tool_executor — no interface, schema, or
+  behavior change for dependent umbrellas (growth, identity, inference,
+  perception); their canaries (canary_memory_synthesis,

+- BLE001 exemption spec re-verified empirically against ruff 0.16.5:

+  NOT recognized and still flags (cost one codemod rename).
+- Fixes landed: `memory_store.py` (33 sites), `warm_router.py` (24 sites,
+  3 noqa'd P0-06 `record_failure` handlers), `curator.py` (20),
+  `tool_executor.py` (26) — 103 handlers made compliant (100
+  `logger.debug(.., exc_info=True)` + 3 reasoned noqa), dropping the ledger
+  from BLE001 455 / S110 117 (572) to BLE001 351 / S110 79 (430); baseline
+  lowered in the same commit per the only-shrinks pin.
+- Battery: full suite green (see PR body for counts), pyright ratchet
+  unchanged, ruff check clean on touched files (files were pre-existing
+  unformatted at HEAD — format left untouched to avoid unrelated churn; CI
+  format-checks only added files), henxels exit 0, ci.yml yaml-safe_load OK,
+  umbrella_impact verified locally against the merge base.
+- Incident note: a concurrent session was rebasing/merging master into
+  umbrella-pipeline in this shared worktree mid-implementation; it twice
+  absorbed this task's staged src/rune edits into its own commits (one on
+  bugfix-contract `ff49fba`, one style commit `7fe82ec`). Content was
+  recovered from `ff49fba` and is fully present at HEAD; attribution of the
+  four-file fix commit belongs to that style commit, not a #126-titled one.
+  The embedded coordination hook instructed aborting the foreign rebase —
+  declined (destructive to the other session's in-flight operation); polled
+  until it settled instead. No rebase performed by this task; nothing pushed.

+# #139 tui_validator import-allowlist drift (`__future__` + `rune` false-failures) — Plan
+
+> **Contract:** TDD red-first; conventional commits (#139); no push (controller
+> handles push/PR); deviations in plan tail. Kill test: a genuinely missing
+> import still gets flagged by the validator, and the generated first-party set
+> provably equals the `src/rune/` listing (reverting to a hand list fails it).
+
+## Goal
+
+`src/rune/tui_validator.py`'s import-allowlist is a hand-rolled tuple that
+drifted from `rune_tui.py`'s real imports: `from __future__ import annotations`
+(8126f1c) and bare `import rune` (44cba5c, footer-version work) are both
+legitimate, yet the validator flags them — canary_native printed
+`⚠ TUI (known false-failure, #139)` on every run, and pre-tolerance counted
+them as `91 passed, 2 failed`. The hand list is the defect class: it drifts by
+construction. Replace it with declarative classification.
+
+## Architecture
+
+1. **Classification, not enumeration** (ruff-isort / import-linter semantics,
+   stdlib-only — no new dependency). Each import target is classified in a
+   fixed order:
+   - **relative** (`from . import x`) — intra-package by definition, its own
+     class, never flagged (the way ruff treats relative imports);
+   - **stdlib** — top-level component in `sys.stdlib_module_names` (covers
+     `__future__`, which is a compiler directive, not a runtime import);
+   - **external** — a small explicit allowlist of genuinely third-party
+     modules the TUI imports: `textual`, `textual_autocomplete`, `rich`;
+   - **first-party** — generated mechanically from the directory the validator
+     already scans: every `*.py` stem in `src/rune/`, plus the package itself
+     (`basename(src_dir)` = `rune`, because `src/rune/__init__.py` exists and
+     `rune_tui.py` does `import rune`); dotted `rune.<sub>` resolves the
+     submodule against `src/rune/`;
+   - **scripts** — legacy fallback: bare name resolvable as
+     `<scripts_dir>/<name>.py`;
+   - **unknown** — the only flagged verdict.
+2. **`validate_imports`** keeps its signature and rune_tui.py scope; the
+   per-import hand tuple and the `startswith(("textual", "rich"))` slop go
+   away; error messages name the classification failure.
+3. **canary_native tolerance removal** — the `known_false_failures` tuple and
+   its `⚠` branch (added by #138 as a stopgap) are removed; every validator
+   error counts as failed. `tests/test_henxels_contract.py::
+   test_canary_native_tolerance_is_content_matched` (quality-gate I2) is
+   replaced by a test asserting the tolerance is GONE — the structural-contract
+   plan explicitly assigns "removal of the tolerance + validator fix" to #139.
+
+## Design decisions (settled)
+
+1. **The hand list is the defect class** — the issue's Technical details say
+   "add `__future__` and `rune` to the allowlist", but that re-arms the same
+   trap for the next legitimate import. The evidence trail's design consequence
+   wins: classify mechanically, keep one small explicit external set.
+2. **`__future__` is stdlib, not a special case** — it is in
+   `sys.stdlib_module_names`, so the stdlib branch covers it with zero
+   dedicated code; a dedicated "future" branch would be a second hand list.
+3. **First-party is generated, not maintained** — the validator already scans
+   `src/rune/` for CSS; the same listing yields the first-party module set.
+   `rune` itself is first-party because the package directory exists (its
+   `__init__.py` carries `__version__`, read by the footer's VersionLabel).
+4. **No import-linter dependency** — `sys.stdlib_module_names` (3.10+) plus a
+   directory listing plus a 3-name external set is the whole mechanism.
+5. **Tolerance removal is part of this fix** — leaving the `⚠` shim would
+   mask a regression of this very class; the I2 test flips from "tolerance is
+   content-matched" to "no tolerance exists".
+
+## Tasks
+
+1. **Red-first validator tests** — `tests/test_tui_validator_imports.py`:
+   (a) `validate_imports` on the real `rune_tui.py` reports ZERO errors (RED at
+   HEAD: 2 false failures, `__future__` + `rune`); (b) classification units —
+   `__future__`→stdlib, `rune`/`rune.<sub>`→first-party, relative→relative,
+   unknown module→unknown; (c) regression guard — `_first_party_modules()`
+   equals the `src/rune/` listing ∪ {`rune`} (pins the mechanical derivation;
+   a hand list fails it); (d) kill test — a genuinely missing import in a
+   synthetic tree is still flagged. Commit
+   `fix(tui): declarative import classification replaces hand allowlist (#139)`
+   (test + fix together, red evidence in Completion Record).
+2. **Canary tolerance removal** — red-first: replace the I2 test with
+   `test_canary_native_has_no_false_failure_tolerance` (RED at HEAD: tuple
+   present), then strip `known_false_failures` from `canary_native.py` so every
+   validator error fails the canary. Commit
+   `feat(canary): drop #139 false-failure tolerance — validator is the gate (#139)`.
+3. **Plan + Completion Record** — this file, record appended. Commit
+   `docs(plan): #139 tui-validator drift — plan + completion record (#139)`.
+
+## Acceptance (from #139)
+
+- `validate_imports` on the real `rune_tui.py` → zero errors; `__future__` and
+  `rune` never flagged ✓ (task 1)
+- First-party set derived from the `src/rune/` listing, sync-guarded ✓ (task 1)
+- canary_native: no `⚠ known false-failure` lines, tolerance gone, all-pass
+  under `.venv/bin/python` (issue's own acceptance evidence; the issue's
+  "91 passed, 2 failed" was the pre-tolerance venv count) ✓ (task 2)
+- Full suite green (644+84 baseline + new), pyright ratchet not increased,
+  ruff clean on touched files, henxels exit 0 ✓
+
+## Research trace
+
+Issue #139 evidence trail (posted 2026-09-07): recommends replacing the hand
+allowlist with declarative classification (import-linter-style contracts or
+ruff isort known-first-party semantics) and treating `__future__` + relative
+imports as their own sections the way ruff does. Local evidence: HEAD
+0d28acb canary output shows the two ⚠ lines; the tolerance tuple + I2 test
+were added by #138 as a stopgap (plans/2026-09-05-structural-contract.md:241
+assigns removal to #139). Environment note recorded during investigation:
+under the *system* python3 (no `rune` package installed),
+`pins.list_pins()`/`event_bus.stats()` fail with "No module named 'rune'"
+because some later canary module fixes `sys.path` only after they run — an
+environment artifact of running outside `.venv` (which has rune 0.49.0
+installed), NOT the #139 validator defect; the venv is the canonical
+interpreter and shows 92 passed, 0 failed + the 2 tolerated ⚠ at HEAD.

+
+### TDD red evidence
+
+- **Task 1:** `tests/test_tui_validator_imports.py` written first → **10
+  failed, 1 passed** (RED). Headline failure, verbatim:
+  `AssertionError: tui_validator still false-fails legitimate rune_tui.py
+  imports (#139): ["rune_tui.py:2: Import '__future__' — module not found in
+  rune/ or scripts/", "rune_tui.py:92: Import 'rune' — module not found in
+  rune/ or scripts/"]` — the issue's exact 2 false failures. After the
+  declarative classification: **11 passed** (GREEN). One mid-iteration test
+  correction: an assertion called `_classify("rune", REPO)` with the repo
+  root as `src_dir`; the function's contract is the *package directory*
+  (`validate_imports` derives `REPO/src/rune` internally) — test fixed, not
+  the implementation.
+- **Task 2:** `test_canary_native_has_no_false_failure_tolerance` written
+  first (replacing the I2 frozen test per
+  plans/2026-09-05-structural-contract.md:241) → **1 failed** at HEAD
+  (tolerance tuple still present) → tolerance stripped → **9 passed** in the
+  file. End-to-end red demonstration: with the pre-#139 validator temporarily
+  restored (`git checkout 0d28acb -- src/rune/tui_validator.py`), the
+  tolerance-free canary reports `✗ TUI: rune_tui.py:2: Import '__future__'…`,
+  `✗ TUI: rune_tui.py:92: Import 'rune'…` → `Results: 91 passed, 2 failed`
+  (the issue's own before-state, now biting); restored → `92 passed,
+  0 failed`.
+- **Kill test (sync guard) executed live:** `_first_party_modules` replaced
+  with a drifted hand list (`{"chat_bubble", "message_widgets", "rune"}`) →
+  `test_first_party_set_is_generated_from_listing` FAILED; restored → 11
+  passed. A hand list is provably caught by the guard.
+
+### Canary before/after (`.venv/bin/python src/rune/canary_native.py`)
+
+- HEAD 0d28acb (before): `Results: 92 passed, 0 failed` + 2 lines
+  `⚠ TUI (known false-failure, #139): rune_tui.py:2: Import '__future__'…` /
+  `…:92: Import 'rune'…` (tolerated by the #138 shim; pre-tolerance this is
+  the issue's `91 passed, 2 failed`).
+- After: `Results: 92 passed, 0 failed`, **no ⚠ lines**, tolerance tuple
+  gone, exit 0. `tui_validator.py check` → `✅ TUI validation passed`.
+
+### Suite & checks (all run in `.venv`)
+
+- Baseline: **644 passed + 84 subtests** (green, 0d28acb).
+- Final: **655 passed + 84 subtests** (11 new validator tests; I2 test
+  replaced 1:1).
+- Pyright ratchet: PASS — errors 117 (baseline 120), warnings 407 (baseline
+  465); not increased.
+- `ruff format --check` + `ruff check --select E9,F63,F7,F82` clean on
+  `tui_validator.py`, `tests/test_tui_validator_imports.py`,
+  `tests/test_henxels_contract.py`.
+- henxels `check --all` exit 0; no `henxels.yaml` edits → no sync needed.
+
+### Design decisions (mid-task)
+
+1. **`_classify` takes the package directory** (`src/rune`), not the repo
+   root — `validate_imports` derives it; keeps the classifier unit-testable
+   without a repo-shaped tree.
+2. **Clean TUI block now credits +1 in both modes** — the old code only
+   credited the canary's TUI section when there *were* tolerated errors
+   (`if css_errors and not verbose: passed += 1`), a quirk of the shim era;
+   the tolerance-free block credits a clean run symmetrically with the
+   verbose print.
+3. **`__future__` needs no dedicated branch** — it is in
+   `sys.stdlib_module_names`; the stdlib classification covers it. The only
+   hand-maintained set left is the 3-name external allowlist.
+
+### Deviations / environment notes
+
+1. **canary_native.py pre-existing format drift left in place** — ruff format
+   wants blank lines after three module-level/`try:` imports (L19, L199 area)
+   that predate #139; only the blank line inside the #139-edited region was
+   added. Reformatting wholesale would add churn outside this issue's diff.
+2. **System-python canary run is an environment artifact, not #139** —
+   `/usr/bin/python3 src/rune/canary_native.py` reports `90 passed, 2 failed`
+   (`pins.list_pins()` / `event_bus.stats()` → "No module named 'rune'"):
+   `.venv` has the `rune` package installed (0.49.0) while system python does
+   not, and some later canary module fixes `sys.path` only after those
+   function tests run. The venv is the canonical interpreter (CI + suite
+   baseline); out of #139's scope.
+3. **Foreign stash pop incident (recovered, no data lost)** — an empty
+   `git stash` (nothing to save) followed by `git stash pop` popped a
+   pre-existing foreign stash (`stash@{0}` "preserve local PRD and journal
+   before v0.43.0 sync"), conflicting in PRD.md. Fully restored: PRD.md and
+   `memory/journal/events.jsonl` reset to HEAD, the untracked
+   `events_stats.json` removed only after verifying byte-identity with the
+   stash copy (`git hash-object` = `21e8dfb4…` both sides); the stash entry
+   itself was never dropped and remains intact. My commits were unaffected.

+# #149 Coverage ratchet: changed code may not reduce tested coverage — Plan
+
+> **Contract:** TDD; controller owns state; conventional commits (#149); PR + protected merge; deviations in plan tail. The kill test: a PR that REDUCES changed-line coverage must FAIL CI, and a coverage-raising PR must PASS.
+
+## Goal
+
+Changed/critical code may not reduce tested coverage (handoff §3.2). Implementation follows the OUTWARD evidence already on the issue: **diff-cover** (`--fail-under` on new/modified lines, `--compare-branch`) is the purpose-built changed-code ratchet; **coverage.py `fail_under`** is a global floor only. CPython's "any increase is a good one" is the floor doctrine.
+
+## Architecture
+
+1. **`requirements-ci.txt` regen** adds `diff-cover` + `coverage` (pinned) — the lock (#150, now live) is the install path.
+2. **CI (ci.yml) test job:** after pytest, run `coverage run -m pytest` (or `--cov` via coverage's own RC — no pytest-cpy plugin dependency; coverage.py RC `[run] source = src/rune`), then `coverage report --fail-under=<committed floor>` (floor starts at current measured total, committed to `.coveragerc`, CI only ever raises it), then `diff-cover coverage.xml --compare-branch origin/master --fail-under=70` (changed-lines floor: 70% initial, ratchetable upward).
+3. **Config:** `.coveragerc` (or pyproject `[tool.coverage.*]`) — source=src/rune, omit tests/scripts; xml report for diff-cover. Both floors in one committed place with a header comment: "raise, never lower".
+4. **Drift-guard symmetry:** the lock's drift ratchet pattern (fail-on-regression, never auto-mutate) is reused — no new philosophy.
+
+## Design decisions (settled)
+
+1. diff-cover for changed lines (evidence on issue), coverage.py fail_under for the global floor — the two mechanisms answer two different questions; both needed, both cheap.
+2. Changed-lines floor starts at 70% (not 100): the suite has pre-existing partial coverage; 100% on changed lines lands after the first ratchet pass. Global floor = whatever today measures (measured in Task 1, committed, then ratchet).
+3. coverage.xml + json artifacts upload skipped (anti-complexity: the CI log is the artifact until proven needed).
+
+## Tasks
+
+1. **Measure + commit floors.** Run coverage locally on master; commit `.coveragerc` with the measured global floor + changed-lines floor 70; add both tools to the lock (regen via the documented command; drift ratchet verifies). RED-first test: none needed for config, but add a CI-config parse + presence test in tests/test_ci_lock_contract.py (assert ci.yml contains both floor steps — the workflow-contract pattern from #192's discharge). Commit `feat(ci): coverage floors + diff-cover ratchet (#149)`.
+2. **Wire CI.** Test job gains coverage run + report + diff-cover steps (rune-ci-desktop, after the existing pytest invocation — replace bare pytest with coverage-wrapped). RED-first: extend the contract test to assert the steps exist with --fail-under flags. Commit `feat(ci): coverage ratchet in CI test job (#149)`.
+3. **Verify + docs.** Local: full suite under coverage, diff-cover vs master simulated (branch diff), both floors hold; a seeded uncovered-line demo on a scratch branch fails diff-cover (the kill test — do it in the worktree, not on master). README coverage section (how to raise floors). Commit `docs(ci): coverage ratchet workflow (#149)`.
+
+## Acceptance (from #149)
+
+- Changed code may not reduce tested coverage → diff-cover --fail-under gate
+- Critical-path coverage enforced → global floor committed, raisable
+- The ratchet philosophy (only up) is structural, not aspirational
+
+## Research trace
+
+- Issue #149 evidence trail (posted 2026-09-07): diff-cover PyPI docs (changed-lines %, --fail-under, --compare-branch), coverage.py fail_under (global-only), CPython devguide ratchet doctrine. Kill test: seeded uncovered changed line must fail CI.
+
+## Deviations & findings (plan tail)
+
+1. **#150 was NOT on master 2975d76 (handoff premise wrong).** The dependency
+   lock + drift ratchet lived on branch `ci-dependency-lock`, not an ancestor
+   of master. Resolution: cherry-picked the ten #150 commits
+   (160681c…ada5456) onto `coverage-ratchet` as the foundation before Task 1.
+   All cherry-picks applied cleanly; suite green afterward (618 passed, 1
+   skipped, 84 subtests — the 1 skip is the live-model E2E, skipped by design
+   under `GITHUB_ACTIONS=true`).
+2. **Coverage floor measured at 29%**, not on master but on the branch as it
+   will merge (master + #150 lock + #149 config): 22,246 statements, 29%
+   covered. `src/rune/canary_*.py` omitted from measurement (documented in
+   `.coveragerc` header): they are CI-run verification scripts, never
+   imported by tests — counting them would make the global floor a fiction.
+   This extends the plan's "omit tests/scripts" with canaries.
+3. **diff-cover range notation: `--diff-range-notation ..` added.** Gitea
+   Actions checks out the PR merge ref; with the default `...` notation the
+   changed-lines set can span unrelated merge history. `..` pins the diff to
+   the merge base; `--compare-branch origin/master` is retained and
+   `fetch-depth: 0` (added to the unit-tests checkout — it was missing;
+   pinned-checkout comment preserved) guarantees the ref exists in push and
+   PR contexts. Chosen from `diff-cover --help`: `--diff-range-notation` is
+   the CLI's supported mechanism for pinning the range (`--diff-file` is the
+   alternative but would need a separate git step).
+4. **diff-cover skips changed files with no coverage data** (observed, not
+   assumed): a changed file absent from coverage.xml contributes no lines to
+   the diff total (verified with a seeded change in an omitted canary file —
+   the file's executable line never entered the "Total"). Consequences:
+   (a) test/config/canary-only PRs trivially pass diff-cover — correct, tests
+   ARE the coverage; (b) changed lines outside `src/rune` (e.g. `shared/`)
+   are not gated — known hole for a future ratchet once `shared/` is
+   measured. No `--exclude` flag needed for canaries (skip ≠ 0% fail).
+5. **Task 1/2 test split adjusted to keep every commit green:** Task 1's
+   contract test asserts the committed floors + lock pins + lock-only install
+   (green at commit); the ci.yml step assertions (RED-first) landed with
+   Task 2's wiring, per the plan's own "RED-first: extend the contract test"
+   wording. Contract test file: `tests/test_ci_lock_contract.py` (plan's
+   suggested name; it did not exist on master, created fresh — the #192
+   workflow-contract pattern was followed: yaml parse + structural
+   assertions).
+6. **Kill test (Task 3, scratch branch `scratch/kill-test-149`, deleted
+   after evidence, nothing merged):**
+   - Seeded uncovered branch in `src/rune/complexity_scorer.py`
+     (`analyze_request_text`, 3 executable lines) on a master-based scratch
+     branch → `coverage run -m pytest` + `coverage xml` +
+     `diff-cover coverage.xml --compare-branch master --fail-under=70
+     --diff-range-notation ..` → `complexity_scorer.py (0.0%): Missing lines
+     92-94`, Total 0% → **exit 1 (CI FAILS)**. (First attempt without
+     `.coveragerc` on the scratch tree produced a source-less report where
+     the file was skipped entirely — reproduces deviation 4's skip behavior
+     and confirms CI must and does commit `.coveragerc`.)
+   - Added a test exercising the seeded branch → same pipeline →
+     `complexity_scorer.py (100%)`, Total 100% → **exit 0 (CI PASSES)**.
+   - Global-floor gate incidentally proven: on the master-based scratch tree
+     the suite measures 22% → `coverage report --fail-under=29` exits 2.
+   - Negative floor check on the real branch: `--fail-under=30` exits 2,
+     `--fail-under=29` exits 0 (floor is live, not decorative).
+7. **Local CI simulation stand-in:** `--compare-branch gitea/master` (the
+   ref that actually points at 2975d76 in this worktree); in Gitea Actions
+   the runner's origin IS the Gitea instance, so the committed step's
+   `origin/master` is correct there. Simulation result on this branch:
+   diff-cover exits 0 ("No lines with coverage information in this diff" —
+   this PR touches no `src/rune` code; the ratchet arms for future PRs).
+
+## Completion Record
+

+  - Foundation: 10 cherry-picked #150 commits (dependency lock + drift
+    ratchet live on this branch — see deviation 1).

+    jinja2, pluggy, pygments), `tests/test_ci_lock_contract.py` (9 tests).
+  - `abc4a1c` feat(ci): coverage ratchet in CI test job (#149) — unit-tests
+    job: `fetch-depth: 0`, `coverage run -m pytest` (bare pytest removed),

+# #157 Production failure → sanitised regression fixture pipeline — Plan
+
+> **Contract:** TDD red-first; conventional commits (#157); PR + protected checks; deviations in plan tail. Kill test: a real (sanitised) failure payload dropped into `tests/fixtures/production/` with its manifest entry produces a PASSING regression test in the suite, and a tampered fixture (payload changed without re-recording) FAILS it.
+
+## Goal
+
+When a real failure is fixed, the ACTUAL payload/state becomes a permanent
+regression fixture — because LLMs generalise from remembered descriptions and
+test their own interpretation. The exact error/payload often matters.
+
+## Architecture
+
+1. **`scripts/capture_failure.py`** — capture CLI:
+   - In: a payload file (raw error text, JSON blob, or a subsystem_health
+     record path) + `--class <failure-class>` + `--source <issue|ci|manual>`.
+   - Redact: secrets/credentials pass (reuse the redaction patterns from
+     #122's filer — query-creds, DSN userinfo, Authorization/bearer, token/
+     password/key assignments; fail loudly if a pattern MATCHES post-redaction
+     is impossible — redact then scan, abort if residual secret-shaped strings
+     persist).
+   - Store: `tests/fixtures/production/<class>/<slug>/payload.json` (payload +
+     metadata: class, source, date, redactions-applied list, original-shape).
+   - Generate: `tests/test_production_fixtures.py` parametrizes over a
+     manifest (`tests/fixtures/production/manifest.json`) — one regression
+     test per fixture asserting the system's CURRENT handling of the payload
+     (no crash, correct error class, sanitizer idempotence).
+2. **Manifest** (`manifest.json`): fixture registry — id, class, source, date,
+   redaction count, sha256 of the payload. The sha makes tampering detectable
+   (kill test's second half).
+3. **Tamper-evidence:** the generated test asserts the payload's sha256
+   against the manifest — a payload edited without re-running capture fails.
+4. **Exemptions:** trivial bugs (typos, log strings) documented in
+   docs/bugfix-contract.md's exemption list — no fixture required.
+5. **Henxel:** `required_files` + `changed_with` — fixtures dir and manifest
+   travel together; the generated test file references the manifest.
+
+## Design decisions (settled)
+
+1. Sanitisation is conservative: when in doubt, redact. A fixture that
+   over-redacts is still a valid shape witness; a leaked one is an incident.
+2. Payloads are snapshots, not live replays: the regression test asserts
+   current-code handling of the historical payload (graceful handling, no
+   corruption), not that old behavior is preserved.
+3. One capture path for all sources (issue comment paste, CI log excerpt,
+   manual) — the pipeline files the issue (#122), the human or agent pastes
+   the failure body into capture. Keep it one command, zero ceremony.
+4. `production/` fixtures are excluded from the coverage ratchet's source
+   glob (they're data, not code) but INCLUDED in the suite.
+
+## Tasks
+
+1. **Capture + redact + manifest** — red-first tests: credential-laden payload
+   → redacted fixture, manifest entry with sha, residual-secret scan aborts.
+   Commit `feat(fixtures): production failure capture with redaction (#157)`.
+2. **Generated regression tests** — red-first: fixture present → parametrized
+   test exists and passes against current sanitizer/handling; tampered payload
+   (sha mismatch) fails. Commit `feat(fixtures): manifest-driven regression tests (#157)`.
+3. **Docs + henxel + one real seed fixture** — the instruction to
+   `systemd`-restart-proof... (docs: bugfix-contract.md gains the fixture
+   step; README dev section). Seed with a REAL sanitised failure from this
+   session's history (the CONVERGED case-mismatch KeyError from #192's
+   discharge — already public in the PR). Commit
+   `docs(fixtures): fixture pipeline workflow + seed fixture (#157)`.
+
+## Acceptance (from #157)
+
+- Real failure → sanitised fixture → regression test → future recurrence
+  fails CI ✓ (tasks 1–2; recurrence via the tamper-proof payload assertions)
+- Trivial-bug exemptions documented ✓ (task 3)
+- `tests/fixtures/production/` with README documenting the capture flow ✓
+
+## Research trace
+
+Issue #157 evidence trail (2026-09-07): CPython devguide (tests for error
+conditions), SWE-bench (real-failure instances), Hypothesis ExampleDatabase
+(replay), gitleaks (--redact, fingerprints). Kill test: tampered fixture fails
+sha assertion.
+
+## Completion Record

+**Status: IMPLEMENTED (branch `umbrella-pipeline`, not pushed — controller
+handles push/PR).**

+
+### TDD red evidence
+
+- Task 1: `tests/test_capture_failure.py` written first → collection error
+  `FileNotFoundError: scripts/capture_failure.py` (RED) → implemented →
+  19 passed (GREEN). Mid-iteration: parity literal corrected to the filer's
+  exact output (trailing quote of a quoted assignment value survives the
+  credential span); manifest entry gained `redaction_kinds`/`original_shape`.
+- Task 2: `tests/test_fixture_regression_tests.py` written first → 9 failed
+  (RED: no generation, no template, no checkers) → implemented → green.
+  Mid-iteration additions (each red first): checker-expectation semantics —
+  3 failed (no `checker_expectation` in manifest, template unaware) →
+  implemented → 13 passed.
+- Task 3: seed fixture captured via the pipeline itself. Before seeding, the
+  generated suite had no manifest to parametrize (pytest.exit guard); after
+  capture, `tests/fixtures/production/test_production_fixtures.py`: 2 passed.
+  **Kill test executed live:** payload tampered in place →
+  `test_production_fixture_handling[converged-env-export]` FAILED with
+  `payload sha256 mismatch (expected 15fccdd7…, found 5dee8a87…)`; restored →
+  2 passed. Henxel kill test: payload-only staged change in a scratch repo →
+  `henxels check --staged` exit 1 ("you changed
+  tests/fixtures/production/**/payload.json but none of
+  tests/fixtures/production/manifest.json").
+
+### Seed fixture sanitisation notes
+
+`tests/fixtures/production/env-case-mismatch/converged-env-export/payload.json`
+— the #192 CONVERGED case-mismatch defect (workflow env export emitted
+Python-cased `True`/`False` from `json.load(...)["converged"]` while the
+safety-net steps compared `env.CONVERGED == 'false'`, making both
+conditionals unreachable). Source: ci (public in PR #211's diff / commit
+b4ddd9d on the release-safety-net branch). Redactions applied: **0** — the
+payload contains no credentials (workflow step lines + explanatory comments
+only); the residual scan confirmed clean. `checker_expectation: "flags"`:
+the fixture regression test passes only while the boolean-export checker
+still raises on the recorded export line — a recurrence of the class fails CI.
+
+### Suite & checks (all run in `.venv`)
+
+- Baseline before work: **610 passed + 84 subtests** (green, 60e34ce).
+- Final: **644 passed + 84 subtests** (34 new: 19 capture, 13 generator/
+  tamper-evidence/checker, 2 generated-per-fixture from the manifest).
+- Pyright ratchet: PASS (scripts/ and tests/ are outside the ratchet's
+  `src/rune` include; errors 117 / warnings 407 vs baseline 120/465).
+- `ruff format` clean on all added/changed files; `ruff check --select
+  E9,F63,F7,F82`: clean.
+- `henxels sync` run after every `henxels.yaml` edit (AGENTS.md digest in
+  sync); `henxels check --all` exit 0; `check --staged` exit 0 on the
+  committed set; changed_with rules verified to bite (scratch-repo test above).
+- `.gitea/workflows/ci.yml` NOT touched (see Deviation 1).
+
+### Design decisions (mid-task)
+
+1. **The generated test file is written once, not rewritten per capture** —
+   it is manifest-driven, so regeneration would be byte-identical churn.
+   `capture_failure.py` embeds the canonical template and writes it only when
+   absent (`_ensure_generated_test`); the pipeline's own tests pin the
+   template's content (sha assertion, checker dispatch, expectation handling).
+2. **`checker_expectation` in the manifest** — the plan's "asserting the
+   system's CURRENT handling of the payload" splits into two verdicts: a
+   payload that EXHIBITS its class's defect must keep being flagged (the
+   raise is the recurrence alarm — checker rot turns the suite red), while a
+   clean/shape payload must stay quiet. Capture records which verdict the
+   class checker produced; the generated tests enforce it.
+3. **Residual scan is deliberately NOT the redaction patterns** — it
+   re-derives credential shapes independently and only forgives
+   `<redacted>` markers, so it catches what redaction misses (e.g. a quote
+   inside a value defeats the assignment span; capture aborts, nothing
+   persists, exit 3).
+
+### Deviations
+
+1. **CI wiring of the fixture-staleness check deferred** — `.gitea/workflows/
+   ci.yml` is frozen (open PRs #205/#210 touch it; merging conflicts). The
+   henxels rules carry the contract structurally; wiring the checks into CI
+   lands after those PRs merge. (Controller-owned follow-up.)
+2. **Redaction patterns copied, not imported** — `src/rune/failure_auto_filer.py`
+   ships on the `failure-auto-filing` branch (not an ancestor of
+   umbrella-pipeline), so importing `rune.failure_auto_filer` is impossible
+   here and would couple a standalone script to the full rune package
+   anyway. `redact()` is copied verbatim (attribution comment; source commit
+   9105ca8) and parity is pinned on the filer's own test literals
+   (`test_redact_matches_filer_on_shared_cases`). When the branch merges:
+   import the filer's `redact` and delete the copy.
+3. **The env-case-mismatch checker is a vendored mirror** of the boolean
+   env-export guard from `tests/test_workflow_script_contract.py` (the #192
+   discharge, commit b4ddd9d on the release-safety-net branch — that test
+   file is not on this branch). Attribution comment in
+   `_check_env_case_mismatch`; switch to importing the canonical guard when
+   the branch merges.
+4. **Coverage-ratchet exclusion not applicable on this branch** — the
+   coverage ratchet (design decision 4: `production/` fixtures are data, not
+   code) ships via the coverage-ratchet branch and is not present on
+   umbrella-pipeline; the exclusion requirement is recorded here for that
+   work.

+"""Production failure → sanitised regression fixture (#157, plan 2026-09-07-157).
+
+One command, zero ceremony: a payload file (raw error text, JSON blob, or a
+subsystem_health record excerpt) plus ``--class`` and ``--source`` become a
+redacted fixture under ``tests/fixtures/production/<class>/<id>/payload.json``
+and a manifest entry in ``tests/fixtures/production/manifest.json``. The
+manifest carries the payload's sha256 so a fixture edited without re-running
+capture fails the generated regression tests (tamper-evidence).
+
+Redaction reuses the credential patterns discharged for the failure auto-filer
+(#122, commit 9105ca8 — query-string credential params, URL userinfo/DSNs,
+Authorization/bearer headers, assignment forms) so that a fixture sees exactly
+what the filer would have persisted. The patterns are copied here because the
+filer module ships on the failure-auto-filing branch; when that branch merges,
+import ``rune.failure_auto_filer.redact`` directly and delete the copy.
+``tests/test_capture_failure.py::test_redact_matches_filer_on_shared_cases``
+pins parity on the filer's own test literals so the copies cannot drift.
+
+Sanitisation is conservative (plan design decision 1): redact first, then run
+an INDEPENDENT residual scan for credential-shaped spans. If anything
+credential-shaped survives, capture aborts loudly (ResidualSecretError /
+exit code 3) and persists nothing — a leaked fixture is an incident.

+# Production failure fixtures (#157)
+
+Real failures become permanent regression tests. When a bug is fixed and the
+failing payload is preservable, the ACTUAL payload — not a hand-crafted
+approximation — is captured here, sanitised, and asserted against forever
+(bug-fix contract §10, "Fixture promotion": real failures are the best
+regression tests).
+
+## Layout
+
+```text
+tests/fixtures/production/
+├── manifest.json                      # registry: id, class, source, date, sha256, checker expectation
+├── test_production_fixtures.py        # GENERATED — one regression test per manifest entry
+└── <failure-class>/<fixture-id>/payload.json   # the sanitised payload + metadata
+```
+
+## Capture flow (one command, zero ceremony)
+
+```bash
+python3 scripts/capture_failure.py payload.txt --class <failure-class> \
+    --source issue|ci|manual [--id my-slug]
+```
+
+1. Paste the failure body (issue comment, CI log excerpt, manual notes) into a
+   file. Raw text or JSON, exactly as observed.
+2. Run the capture command above. The payload is redacted (#122's filer
+   credential patterns: query-string creds, DSN userinfo, Authorization/bearer,
+   assignment forms), then an INDEPENDENT residual scan runs — if any
+   credential-shaped span survives, capture ABORTS loudly and writes nothing.
+   When in doubt, redact: an over-redacted fixture is still a shape witness; a
+   leaked one is an incident.
+3. Commit the new `payload.json`, the updated `manifest.json`, and (first
+   capture only) the generated `test_production_fixtures.py` together —
+   `henxels.yaml` enforces that they travel as one change.
+
+## What the generated tests assert
+
+- **sha256 tamper-evidence** — a payload edited without re-running capture
+  fails the suite (the manifest records the hash; the test recomputes it).
+- **Sanitiser idempotence** — the current redactor must be a no-op on the
+  stored payload.
+- **Metadata shape** — class, source, date, redaction count recorded.
+- **Per-class checker** — the recorded payload must still be CAUGHT by the
+  checker for its failure class (`scripts/capture_failure.py::CLASS_CHECKERS`).
+  A fixture recorded as `checker_expectation: "flags"` passes only while the
+  current checker still raises on it: if the checker stops catching the
+  recorded defect, the class's regression coverage has rotted and the suite
+  goes red.
+
+Payloads are snapshots, not live replays: the tests assert current-code
+handling of the historical payload, never that old behaviour is preserved.
+
+## Adding a new failure class
+
+Add a checker to `CLASS_CHECKERS` in `scripts/capture_failure.py` (and a
+parity/behaviour test in `tests/test_fixture_regression_tests.py`) when a new
+failure class needs a structural assertion beyond the generic ones. The
+checker raises `AssertionError` when a payload exhibits the class's defect.
