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

## Metadata

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

---

## Executive Summary

`OBPI-0.3.0-05` closes the final ADR-0.3.0 parity-scan execution gap by making canonical-root resolution deterministic and fail-closed in operator-facing control surfaces.

Closures in this OBPI:

1. Canonical-root resolution order is explicit and stable.
2. Fail-closed policy is explicit for missing canonical sources.
3. Habit-class reporting requirement is explicit in parity reporting template.
4. Runbook now includes canonical-root parity-scan rules.

## Habit Parity Matrix

| Habit Class | Canonical Source Signal (AirlineOps) | gzkit Surface(s) | Status | Severity | Evidence |
|---|---|---|---|---|---|
| Pre-tool orientation | verify canon path before parity claims | skill prerequisites + runbook parity section | Parity | P3 | sibling/absolute checks captured |
| Tool-use control surfaces | deterministic canonical-root resolution order | skill steps + parity template required section | Parity | P2 | explicit ordered strategy |
| Post-tool accounting | parity claims backed by dated evidence | dated parity + habit reports | Parity | P2 | 2026-02-15 OBPI-05 reports |
| Validation | command-based proof surface checks | `gz cli audit`, `gz check-config-paths`, docs/validate | Parity | P3 | command passes recorded |
| Verification | fail-closed behavior on unresolved canonical source | skill/template/report language | Parity | P2 | `canonical-root` + `fail closed` evidence |
| Presentation for humans | operator-readable doctrine in runbook/report | runbook + report template + report output | Parity | P3 | clear linkage to ADR/OBPI |
| Human authority boundary | OBPI closure does not auto-close ADR | OBPI completion + ADR status/gates | Parity | P3 | ADR-0.3.0 Gate 5 remains separate |

| Prior Gap | Prior Status | Current Status | Closure Artifact |
|---|---|---|---|
| Deterministic parity scan execution | Partial | Parity | `.github/skills/airlineops-parity-scan/SKILL.md`, `docs/proposals/REPORT-TEMPLATE-airlineops-parity.md`, `docs/user/runbook.md` |

## Verification Evidence

```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
uv run gz cli audit
uv run gz check-config-paths
```

Observed:

- sibling root present
- absolute fallback present
- required canonical-root/fail-closed/habit-matrix terms detected in skill/template/report surfaces
- `gz cli audit` PASS
- `gz check-config-paths` PASS

## Closure Statement

`OBPI-0.3.0-05-parity-scan-path-hardening` is complete for evidence-first scope: deterministic canonical-root parity behavior, fail-closed doctrine, and required habit parity matrix reporting are now explicit and verified in gzkit control surfaces.
