# REPORT: AirlineOps Parity Scan (OBPI-0.3.0-05 Closure)

## Metadata

- Date: 2026-02-15
- Scanner: Human + Agent
- Canonical Source: `/Users/jeff/Documents/Code/airlineops`
- Scope: `OBPI-0.3.0-05-parity-scan-path-hardening`
- Parent ADR/OBPI: `ADR-0.3.0` / `OBPI-0.3.0-05`

---

## Executive Summary

- Overall status for OBPI-05 scope: **Closed**
- Deterministic canonical path resolution: **Verified**
- Fail-closed parity-scan behavior: **Documented and required**
- Habit-class parity output requirement: **Required in template + emitted in report**

---

## Canonical-Root Resolution Evidence (Required)

- Resolution order used:
  1. explicit override (if provided)
  2. sibling path `../airlineops`
  3. absolute fallback `/Users/jeff/Documents/Code/airlineops`
- Selected canonical root for this run: `/Users/jeff/Documents/Code/airlineops`
- Fallback engaged: no (sibling path is present; absolute fallback also present)
- Fail-closed statement: if no candidate resolves, stop and report blockers; do not emit parity conclusions.

Evidence commands and observed outcomes:

```bash
test -d ../airlineops && echo "sibling present" || echo "sibling missing"
test -d /Users/jeff/Documents/Code/airlineops && echo "absolute fallback present" || echo "absolute fallback missing"
rg -n "Habit Parity Matrix|canonical-root|fail closed" \
  .github/skills/airlineops-parity-scan/SKILL.md \
  docs/proposals/REPORT-TEMPLATE-airlineops-parity.md \
  docs/proposals/REPORT-airlineops-habit-parity-*.md
```

Observed:

- `sibling present`
- `absolute fallback present`
- required terms are present across skill/template/report surfaces

## Canonical Coverage Matrix (OBPI-05 Scope)

| Canonical Artifact (AirlineOps) | gzkit Counterpart | Status | Severity | Evidence |
|---|---|---|---|---|
| parity-scan canonical-root ritual | `.github/skills/airlineops-parity-scan/SKILL.md` | Parity | P2 -> Closed | Resolution order + fail-closed requirement recorded |
| parity report requirements | `docs/proposals/REPORT-TEMPLATE-airlineops-parity.md` | Parity | P2 -> Closed | Canonical-root section + required Habit Parity Matrix |
| operator execution guidance | `docs/user/runbook.md` | Parity | P2 -> Closed | Canonical-root deterministic/fail-closed rule documented |

## Behavior / Procedure Source Matrix

| Behavior Class | Canonical Source(s) | gzkit Source(s) | Status | Severity | Evidence |
|---|---|---|---|---|---|
| Pre-tool orientation | parity-scan prerequisites | skill + runbook prechecks | Parity | P3 | canonical-root rule documented |
| Tool-use control surfaces | parity-scan ordered strategy | skill steps + report template section | Parity | P2 | explicit resolution order |
| Post-tool accounting | report evidence obligations | dated parity/habit reports | Parity | P2 | dated closure artifacts |
| Validation | command contracts | `gz cli audit`, `gz check-config-paths`, docs checks | Parity | P3 | command pass outcomes recorded |
| Verification | fail-closed doctrine | skill/template/report text | Parity | P2 | fail-closed statements present |
| Presentation | operator-readable reporting | proposal reports + runbook | Parity | P3 | direct linkage to ADR/OBPI |
| Human authority boundary | attestation doctrine | OBPI closeout + ADR-level separation | Parity | P3 | ADR completion remains separate |

## Habit Parity Matrix (Required)

| Habit Class | Canonical Source Signal | gzkit Surface(s) | Status (Parity/Partial/Missing/Divergent) | Severity (P0-P3) | Evidence |
|---|---|---|---|---|---|
| Pre-tool orientation | canonical path prerequisites before claims | skill prerequisites + runbook | Parity | P3 | precheck commands captured |
| Tool-use control surfaces | deterministic canonical-root order | skill + template + report | Parity | P2 | ordered strategy recorded |
| Post-tool accounting | dated, reproducible proof artifacts | `docs/proposals/REPORT-airlineops-*-2026-02-15-obpi-05.md` | Parity | P2 | dated closure reports |
| Validation | explicit command checks | CLI/doc checks below | Parity | P3 | all checks pass |
| Verification | fail-closed parity claims | skill/template wording | Parity | P2 | fail-closed evidence present |
| Presentation for humans | clear scope and linkage | report sections + runbook | Parity | P3 | ADR/OBPI linkage present |
| Human authority boundary | OBPI completion vs ADR attestation split | OBPI closure report + ADR status | Parity | P3 | ADR Gate 5 still pending |

## Verification Evidence

Executed command set:

```bash
uv run gz cli audit
uv run gz check-config-paths
uv run mkdocs build --strict
uv run gz validate --documents
uv run gz adr status ADR-0.3.0 --json
```

Observed:

- `uv run gz cli audit` -> PASS
- `uv run gz check-config-paths` -> PASS
- `uv run mkdocs build --strict` -> PASS
- `uv run gz validate --documents` -> PASS
- `uv run gz adr status ADR-0.3.0 --json` -> PASS (OBPI-05 now expected to be completed after brief status update)

---

## Findings Status

### F-005: Parity scan path resolution fragility in worktree/non-worktree contexts

- Prior status: Partial (P2)
- Current status: **Resolved in gzkit**
- Closure evidence:
  - ordered canonical-root strategy documented and enforced at skill/report/runbook surfaces
  - fail-closed claim discipline documented
  - required habit-class matrix output now explicit in parity report template

---

## Required Next Actions

1. Re-run full ADR quality gates and record heavy-lane closeout evidence for `ADR-0.3.0`.
2. Keep weekly parity cadence with dated report artifacts.
3. Perform ADR-level human attestation only after remaining ADR gate requirements are satisfied.
