## Feature Demonstration (Step 3 — MANDATORY)

ADR-0.0.59 ships a three-kind REQ taxonomy (BEHAVIOR / SUPPORT / STRUCTURAL-FENCE) that routes each requirement to its correct proof channel, ending the era of tautological grep tests gating CI on the wrong signal class.

### Capability 1: Per-REQ proof-channel introspection

```bash
$ uv run gz covers OBPI-0.0.59-03 --json
```

Each REQ entry now carries `taxonomy_kind`, `proof_channel`, `proof_status`, `ledger_event_ids`, `parent_adr_anchor`. Summary line: `"behavior_uncovered_reqs": 0, "grandfathered_reqs": 1`. Example entry:

```json
{
  "req_id": "REQ-0.0.59-03-01",
  "taxonomy_kind": "BEHAVIOR",
  "proof_channel": "TEST_COVERS",
  "proof_status": "pass",
  "ledger_event_ids": [],
  "parent_adr_anchor": null
}
```

**Why it matters:** The operator can now see, per REQ, which evidence channel carries the proof — and whether that channel reports pass — without conflating BEHAVIOR coverage with SUPPORT or STRUCTURAL-FENCE artifacts.

### Capability 2: Brief-authoring fail-close

```bash
$ uv run gz validate --req-kind-discipline
Validated: req_kind_discipline
✓ All validations passed (1 scopes).
```

**Why it matters:** Authors writing a content-evidence REQ can now tag it `[SUPPORT]` and cite a ledger event + structural validator instead of forging a tautological `@covers` test to satisfy the prior single-channel gate.

### Capability 3: Tautological-test drift gate

```bash
$ uv run gz validate --tautological-test-audit
Validated: tautological_test_audit
✓ All validations passed (1 scopes).
```

Backed by `data/tautological_test_baseline.json` (765 operations) + `data/tautological_test_waivers.json`.

**Why it matters:** The gate fails closed the moment a new filesystem-shaped grep test creeps in above baseline — drift is caught at the commit, not at the next quarterly audit.

### Capability 4: Decommissioning chore

```bash
$ uv run gz chores list   # excerpt
decommission-tau…  heavy  1.0.0  3  Decommission Tautological Tests (ADR-0.0.59-04)
```

Runnable via `uv run gz chores run decommission-tautological-tests`.

**Why it matters:** The operator has a single named, runnable surface for retiring the ~3,400 legacy grep tests — work is enumerated, not improvised.

### Capability 5: Clean audit-check signal

```bash
$ uv run gz adr audit-check ADR-0.0.59
PASS All linked OBPIs are completed with evidence.
  - OBPI-0.0.59-01-author-doctrine-and-supersession
  - OBPI-0.0.59-02-req-kind-discipline-validator
  - OBPI-0.0.59-03-parity-gate-three-channel-extension
  - OBPI-0.0.59-04-decommission-tautological-tests-chore
  - OBPI-0.0.59-05-first-sweep-wave-top-5-offenders
Advisory 17 REQ(s) without @covers traceability (non-blocking):
  ...
```

**Why it matters:** SUPPORT and STRUCTURAL-FENCE REQs now route to their correct proof channels — what would have been 17 hard fails before the taxonomy ships as 17 advisories, and Gate 2 verdicts reflect behavior coverage truthfully.

### Value Summary

The operator can now author a brief whose REQs honestly say what kind of evidence each one demands — behavior tests, ledger events with validators, or parent-ADR boundary anchors — and gzkit routes each through the appropriate gate without forcing tautological proof. Brief-authoring drift is fail-closed at `--req-kind-discipline`; tautological-test creep is fail-closed at `--tautological-test-audit`; legacy debt is enumerated as a named chore. The structural emergency where CI gated on the wrong signal class is closed.

## Recommendations

The two independent reviewers concur: VALIDATED proceeds; the shortfalls are real but non-blocking and route to follow-up GHIs. The ADR ships the taxonomy + scaffold + chore as authored; the depth of two proof channels' resolution is the named follow-up surface.

### 2026-05-31 unit-testing doctrine follow-up

[`FOLLOW_UP_UNIT_TESTING_DOCTRINE_2026-05-31.md`](FOLLOW_UP_UNIT_TESTING_DOCTRINE_2026-05-31.md)
records the post-validation unit-testing deep dive requested under GHI #571.
It confirms ADR-0.0.59 is the correct design response to GHI #531 and routes
the remaining recurrence-defense findings to the related GHIs:

- hot-path unit-test wording should explicitly say only BEHAVIOR REQs produce
  `@covers` unit tests;
- `gz-obpi-pipeline` evidence language still treats `@covers location` as
  universal and should be rewritten as proof-channel-specific;
- `gz obpi complete` still applies old `discover_covers()` pressure at
  completion time, tracked by GHI #537;
- the tautological-test scanner is a growth gate, not a cleanup report, and
  needs inventory output before broad cleanup waves;
- output/render assertion detection should begin advisory-only until
  output-contract fixture markers exist.

### Follow-up GHIs to file (5 from quality-reviewer + 1 from spec-reviewer)

1. **SUPPORT channel: implement actual ledger-event query** — currently `_check_support_req` (`src/gzkit/commands/validate_cmd.py:403-425`) regex-matches REQ prose for `"gz validate --"` AND any of `{artifact_edited, obpi_created, ledger, event}`; no ledger query is made. `compute_three_channel_coverage` hardcodes `proof_status = "advisory-support"` (`src/gzkit/req_kind.py:218`). The "LEDGER_PLUS_VALIDATOR" channel name overstates what runs. Implement actual `gz events query` against `artifact_edited` events citing the asserted path + structural-validator dispatch.

2. **STRUCTURAL-FENCE channel: per-REQ anchor resolution** — currently `_check_structural_fence_req` (`validate_cmd.py:428-450`) verifies only that the parent ADR has a `## Boundary Invariants` heading present, not that a per-REQ anchor exists inside. Coverage path hardcodes `"grandfathered"` (`req_kind.py:220`). Implement per-REQ anchor resolution.

3. **`req_kind_grandfathering.json` schema-less** — loaded as raw `dict[str, str]` with `contextlib.suppress(json.JSONDecodeError, OSError)` (`covers.py:219-224`). Author a Pydantic model with `extra="forbid"` per `.gzkit/rules/models.md`.

4. **`ReqCoverageRecord.ledger_event_ids` and `parent_adr_anchor` declared but never populated** by `compute_three_channel_coverage` (`req_kind.py:98-103, 222-228`). Either populate them or remove from the model (lying schema is worse than missing schema).

5. **Bypass asymmetry** — `--bypass-req-kind-discipline-once` exists on `gz covers` (`covers.py:179-227`) but not on `gz validate --req-kind-discipline` (`validate_cmd.py:538-548`). The ADR's universal-bypass mandate calls for parity; either add the bypass to `gz validate` or document the deliberate asymmetry in the ADR.

6. **REQ-05-04 borderline retag doctrine clarification** — "`gz test` exits 0 after sweep" is a suite-pass post-condition retagged BEHAVIOR→SUPPORT. SUPPORT-with-`--tautological-test-audit`-as-validator is internally consistent, but it sits closer to STRUCTURAL-FENCE ("suite invariance under sweep") than SUPPORT. Worth a doctrine clarification on suite-level post-conditions in the SUPPORT-vs-STRUCTURAL-FENCE boundary.

Filing route: `/ghi-author` (per Behavior Rule 13 — no direct `gh issue create`). Operator pacing.

### Closeout-noted follow-ups (already tracked in OBPI-05 § Tracked Defects)

OBPI-05 brief logs 3 legacy-REQ reclassification defects: REQ-0.0.17-04-10, REQ-0.0.32-07-08, REQ-0.0.32-07-09 — legacy BEHAVIOR REQs whose `@covers` coverage was removed during sweep without grandfathering-cache amendment. Tracked correctly; separate defect class from the audit-finding GHIs above.

### Accept as shipped

- Closed-set discipline (`ReqKind` frozen StrEnum with `extra="forbid"`)
- BEHAVIOR channel end-to-end (`@covers` reachability via `compute_coverage`)
- Drift gate semantics + AST scanner + baseline/waiver Pydantic schemas
- Bypass ledger emission on `gz covers`
- Validator scope registration in `parser_maintenance.py`

## Attestation

I attest that ADR-0.0.59-req-scope-discipline-and-test-shape-doctrine is
implemented as intended, evidence is reproducible from the proofs/
directory, all 5 OBPIs are ledger-attested complete, and the integrated
capability demonstrated in Step 3 exercises the three-channel taxonomy at
the operator surface. Five follow-up GHIs are filed for in-code
channel-depth shortfalls; none are blocking.
