## Feature Demonstration *(narrator lens)*

ADR-0.0.57 delivers a single coherent shift in governance posture: **foundation ADR IDs stop pretending to be a work-order, and a triage skill takes over the prioritization that the odometer used to imply.** The audit demonstrates each delivered capability with live tooling against the project's own governance corpus.

### Capability 1 — Foundation IDs are nominal, sparse-set capable

> *Why this matters:* Operators can pull the highest-impact foundation next, not the lowest-numbered one. The corpus is structurally ready for retired foundations (gaps) without taxonomy errors.

```
$ ls docs/design/adr/foundation/ | grep -E '^ADR-0\.0\.[0-9]+-' | sed -E 's/.*0\.0\.([0-9]+)-.*/\1/' | sort -n
1 2 3 4 ... 56 57 58
```

Current corpus is contiguous 1..58. The nominal-ID doctrine permits but does not require sparsity; the moment a foundation is retired, the gap stays.

### Capability 2 — `gz plan create --kind foundation` uses next-free-integer (gap-fill) allocator

> *Why this matters:* Foundation IDs become identifiers, not sequence positions. Retiring 0.0.42 and creating a new foundation should reuse 0.0.42, not advance to 0.0.59.

Live runs against synthetic corpora (full output in `proofs/demo-capability.txt`):

```
Real corpus (1..58 contiguous) → next free is 0.0.59   ✓
Sparse {1,3,5,7}              → next free is 0.0.2    ✓ (gap-fill, NOT 0.0.8)
Contiguous {1..10}            → next free is 0.0.11   ✓
Empty foundation dir          → next free is 0.0.1    ✓ (bootstrap)
```

Implementation anchor: `src/gzkit/commands/plan.py:113` `_next_free_nominal_foundation_id`.

### Capability 3 — `gz validate --taxonomy` admits sparse sets without sequence-position assumption

> *Why this matters:* The mechanical taxonomy validator is the structural defense against silent breakage from tools assuming foundation IDs are ordered. ADR-0.0.57 § Consequences Negative #3 names exactly this risk; the audit confirms the defense holds.

```
$ uv run gz validate --taxonomy
Validated: taxonomy
✓ All validations passed (1 scopes).
```

REQ-01-03 covers this via `trust_audits.py` carrying the explicit audit record; REQ-01-04 covers the doctrine amendments in ADR-0.0.17/18.

### Capability 4 — `gz-foundation-triage` skill registered and operator-discoverable

> *Why this matters:* The skill is the named replacement for the odometer's implicit ordering pressure (ADR Consequences Negative #4). Without discoverability, the operator has no obvious mechanism to pull next-highest-impact foundation.

```
$ uv run gz skill list | grep foundation-triage
│ gz-foundation-triage       │ Rank the in-flight foundation backlog by ...
```

Three-step body present (Step 1 mechanical pre-pass → Step 2 agent cognitive pass → Step 3 deterministic rendering). Script exposes `--format {json,rank}`. **Caveat:** Step-1 mechanical helper returns empty against the real corpus due to S-01 below; the skill body and surface are correct, the gather helper is regressed.

### Capability 5 — ADR-0.0.17 + ADR-0.0.18 carry the nominal-ID amendment; `trust_audits.py` records the sequence-position audit

> *Why this matters:* Two foundation ADRs were amended in place under ADR-0.0.57; the amendment dates the change, names the source ADR, and threads through `trust_audits.py` so any future taxonomy work has the audit record present.

ADR-0.0.18 carries the literal block:

```
## Amendment 2026-05-23 — ADR-0.0.57
...nominal integer doctrine...
```

`src/gzkit/trust_audits.py` references `ADR-0.0.57` and `sequence-position assumptions` (REQ-01-03 covered).

### Capability 6 — AGENTS.md ordering-rule scope shrunk to feature ADRs, with foundation counter-rule

> *Why this matters:* The Local Agent Rules block is the agent contract surface; without the counter-rule, agents would continue treating foundation IDs as semver-ordered. The counter-rule cites ADR-0.0.57 § Decision item 1 + 3 by name, anchoring the rule-scope shrink to its doctrine source.

```
- Apply semantic-version ordering in feature-ADR summaries, ... over feature ADRs.
- Counter-rule (foundation ADRs): Foundation ADR IDs (0.0.x) are nominal integers
  — unique identifiers, not sequence positions. Do not order, sort, or compare
  foundation IDs as semver; foundations have no semantic ordering and may form
  sparse sets (e.g. 0.0.54, 0.0.56 with 0.0.55 absent is valid). Doctrine:
  ADR-0.0.57 § Decision item 1; rule-scope shrink: ADR-0.0.57 § Decision item 3.
```

## Spec-reviewer findings *(independent requirement-tracing)*

Each Decision claim was traced from ADR prose → OBPI brief REQs → covering tests → live behavior.

- **C-1 (nominal-ID doctrine)** → REQ-01-04 covers ADR-0.0.17/18 amendment blocks; REQ-01-03 covers `trust_audits.py` audit record. Both tests pass; doctrine is anchored in three places (two ADRs + audit module). ✓
- **C-2 (allocator)** → REQ-02-01..06 cover next-free-integer behavior, gap-fill, bootstrap; OBPI-02 attestation cites 6/7 mechanical REQs + REQ-07 attestation-self. Allocator runs correctly under live synthetic-corpus tests. ✓
- **C-3 (triage skill)** → REQ-03-01..06 cover frontmatter compliance, three-step body, registration, ephemeral invariant, script existence. **Coverage drift:** REQ-03-02 asserts the skill body's prose carries Step-1/2/3 headings in order; it does NOT assert `gather_records()` returns non-empty against an in-flight fixture. The test passes while the helper is regressed against the real corpus. See Shortfall S-01.
- **C-4 (rule-scope shrink)** → counter-rule lands in AGENTS.md citing ADR-0.0.57 § Decision item 1 and 3 by name. ✓

Uncovered REQ analysis (the 2 advisory items from `audit-check`):

- **REQ-0.0.57-01-05** — *"`src/gzkit/commands/plan.py` is unchanged in this OBPI"* — boundary invariant. Verifiable by git diff per-OBPI, not by a unit test (testing a negative file-change is structurally awkward). Correctly classified advisory.
- **REQ-0.0.57-02-07** — *"Gate 5 human attestation recorded with operator name"* — the attestation is the ledger receipt itself; no test asserts its own existence. OBPI-02's `attested_completed` entry in `logs/obpi-audit.jsonl` is the evidence. Correctly classified advisory; the OBPI-02 attestation_text explicitly names this REQ as "the attestation itself."

Verdict: requirement-coverage integrity holds; the two advisory REQs are correctly non-testable; no covers-backfill anti-pattern detected.

---

## Quality-reviewer findings *(structural coherence)*

- **OBPI cohesion** — the five OBPIs decompose cleanly along surface boundaries: doctrine (01) → runtime contract (02) → operator-facing skill body (03) → rubric scoring layer (04) → docs/runbook surface (05). No OBPI crosses brief boundaries; each lands a single coherent surface. ✓
- **Port/adapter framing** — the ADR self-declares as a *port* (nominal-ID invariant + priority-triage contract), with allocator + skill as adapters behind it. Implementation respects that: `_next_free_nominal_foundation_id` is a thin pure function; `gather_records` is a thin script-bundled helper; rubric is a separate module. Architectural framing matches implementation. ✓
- **Stdlib-first** — triage script is stdlib-only (re, json, argparse, pathlib). Allocator is stdlib-only. Rubric (OBPI-04) adapts gzkit's own `gzkit.adr_eval.DimensionScore` rather than introducing a new dependency. ✓ Aligns with AGENTS.md § Stdlib-First doctrine.
- **Structural defect** — see S-01: the script's `gather_records` filter assumes ADR IDs contain `-foundation-` as an infix. Real ADR IDs are `ADR-0.0.N-<arbitrary-slug>` where the slug rarely contains `-foundation-`. This is a **structural mismatch between the script's ID model and the project's actual ID convention** — not a typo. The skill is correctly registered, has the right three-step shape, and runs cleanly; it just gathers nothing useful.

## Shortfalls

| ID | Severity | Title | Routing |
|---|---|---|---|
| **S-01** | non-blocking | `gz-foundation-triage` `gather_records` filter excludes all real foundation ADR IDs due to `-foundation-` split assumption | File GHI under label `defect`, route to a fresh OBPI under a follow-up brief — full evidence in `proofs/shortfall-S01.txt` |
| **S-02** | procedural (non-blocking) | Persona-dispatch subagents (`spec-reviewer`, `quality-reviewer`, `narrator`) executed in-line by the driver because no Task/Agent dispatch tool is exposed in this environment | Surface to operator; if Auto Mode environments need to honor persona-dispatch mechanically, a separate ADR-pool item could codify how to handle dispatch-tool-absent ceremonies. Non-blocking for this ADR's validation. |

### S-01 detail

- **Symptom:** `uv run python .gzkit/skills/gz-foundation-triage/scripts/triage.py --format json` returns `[]` against a corpus with 22 in-flight foundation ADRs (16 Draft + 6 Proposed).
- **Root cause:** `.gzkit/skills/gz-foundation-triage/scripts/triage.py:125`
  ```python
  adr_short = adr_id.split("-foundation-", 1)[0] if adr_id else ""
  if not _FOUNDATION_ID_PATTERN.match(adr_short):
      continue
  ```
  where `_FOUNDATION_ID_PATTERN = re.compile(r"^ADR-\d+\.\d+\.\d+$")`. Real frontmatter IDs are full slugs (`ADR-0.0.38-evidence-authority-projection-doctrine`); the split is a no-op, and the strict ID-only regex then rejects every slug. Only ADR-0.0.57's own slug happens to start `ADR-0.0.57-foundation-`, so its split produces `ADR-0.0.57` — but that ADR is Completed, not in-flight, and is filtered out at the status check above.
- **Why REQ-03-02 doesn't catch it:** that test asserts the SKILL.md prose contains `Step 1`/`Step 2`/`Step 3` headings in order. It does not exercise `gather_records()` against a fixture with in-flight foundation ADRs. Tests-assert-semantics-not-strings invariant (AGENTS.md § DO IT RIGHT #6, `.gzkit/rules/tests.md` § Invariant 6f) prescribes the remediation: author a semantic test that constructs an in-flight foundation ADR fixture and asserts `gather_records()` returns it.
- **Why audit doesn't block:** the ADR claims the skill *exists*, is *registered*, runs *ephemeral diagnosis only*, and produces a *structural-only output*. All four hold. The skill ships unable to gather real corpus content, which is a sub-claim of REQ-03-02 covered only at prose level — but the ADR's stated capability ("Author the gz-foundation-triage on-demand skill") is delivered. The capability *quality* is degraded; the capability *delivery* is not.
- **Proposed remediation:** file GHI through `/ghi-author` with class `defect/skill-impl`; fix in fresh OBPI; semantic test must construct an in-flight foundation ADR fixture and assert `gather_records()` includes it.

### S-02 detail

The skill's Persona Dispatch table requires `spec-reviewer`, `quality-reviewer`, and `narrator` to run as independent subagents (the audit's *whole point*, per the operator's instructions). The available tool surface in this background-job environment does not expose Task/Agent/dispatch tools. The driver executed each lens in-line with labeled section markers (`[spec-reviewer]`, `[quality-reviewer]`, `[narrator]`) so the operator can see which lens produced which finding. Surfaced rather than papered over per AGENTS.md § Prime Directive #5.

## Attestation block

| Phase | Status | Attested by | Date |
|---|---|---|---|
| OBPI completion (Gate 5 × 5) | attested | Jeffry | 2026-05-23 |
| ADR Closeout (closeout_initiated → attested → lifecycle Completed) | attested | Jeffry | 2026-05-23 |
| Audit recommendation | RECOMMEND VALIDATED with non-blocking shortfalls S-01, S-02 routed to GHIs | agent (pipeline-orchestrator persona) | 2026-05-23 |
| Audit acceptance (Gate 5 — pending operator verbal ack) | awaiting `accept audit` / `verify audit` | Jeffry | (pending) |

Per skill Step 8, the operator's verbal `accept audit` / `verify audit` IS the Gate-5 attestation event; this audit document is presented to the operator for that ack before `gz adr emit-receipt --event validated` runs.
