# OBPI-0.11.0-02-obpi-completion-validator-and-git-sync-gate: OBPI completion validator and git-sync gate

## ADR Item

- **Source ADR:** `docs/design/adr/pre-release/ADR-0.11.0-airlineops-obpi-completion-pipeline-parity/ADR-0.11.0-airlineops-obpi-completion-pipeline-parity.md`
- **Checklist Item:** #2 -- "Deliver the blocking completion validator pipeline with changed-files audit and git-sync enforcement."

**Status:** Completed

## Objective

Deliver the fail-closed pre-completion validator that checks evidence quality,
allowlist compliance, changed-files audit, git-sync readiness, and heavy-lane
human-attestation prerequisites before an OBPI can truthfully transition to
`Completed`.

## Lane

**Heavy** -- This unit changes completion behavior and blocker semantics for
operator-facing governance workflows.

## Allowed Paths

- `src/gzkit/hooks/**` -- completion validator and hook integration
- `src/gzkit/cli.py` and `src/gzkit/commands/**` -- command surfaces that invoke validation
- `src/gzkit/ledger.py` and `src/gzkit/schemas/ledger.json` -- blocker/evidence schema if required
- `tests/**` and `features/**` -- validator regression and acceptance coverage
- `docs/user/commands/**` and `docs/governance/GovZero/**` -- validator behavior docs
- `docs/design/adr/pre-release/ADR-0.11.0-airlineops-obpi-completion-pipeline-parity/**` -- ADR/OBPI evidence and linkage

## Denied Paths

- `../airlineops/**`
- Any implementation that silently downgrades scope breaches to warnings
- Any implementation that bypasses heavy-lane human attestation
- New dependencies or external services

## Requirements (FAIL-CLOSED)

1. REQUIREMENT: Completion MUST fail when changed files fall outside the OBPI allowlist.
1. REQUIREMENT: Completion MUST fail when required evidence sections are missing or placeholder-only.
1. REQUIREMENT: Completion MUST fail when required git-sync readiness checks are not satisfied.
1. REQUIREMENT: Heavy and foundation completion MUST not pass without the required human-attestation evidence.
1. NEVER: Treat out-of-scope work or hard git-sync blockers as compatible with completion.
1. ALWAYS: Emit concrete blocker messages that name the failed prerequisite.

> STOP-on-BLOCKERS: if prerequisites are missing, print a BLOCKERS list and halt.

### Value Narrative

Before this tranche, gzkit had partial OBPI completion enforcement spread
across hooks and docs, but there was no single fail-closed validator command
that operators could run to prove completion readiness. Scope drift, placeholder
evidence, unsafe `SKIP` usage, and missing heavy-lane attestation were easy to
reason about informally but not enforced through one stable surface.

After this tranche, `gz obpi validate <obpi-brief>` is the concrete
pre-completion gate. It audits the live changed-file set against `Allowed
Paths`, rejects non-substantive `Implementation Summary` and `Key Proof`
sections, enforces heavy/foundation attestation prerequisites, and reports hard
git-sync readiness blockers through deterministic `BLOCKERS:` output. Dirty but
allowlisted work remains syncable-state, matching the AirlineOps validator
reference; clean-tree enforcement stays in the recorder/sync tranche rather
than being misapplied here.

### Key Proof

```text
Concrete operator surface:

$ uv run gz obpi validate docs/design/adr/pre-release/ADR-0.11.0-airlineops-obpi-completion-pipeline-parity/obpis/OBPI-0.11.0-02-obpi-completion-validator-and-git-sync-gate.md
OBPI Validation Passed: OBPI-0.11.0-02-obpi-completion-validator-and-git-sync-gate.md

Blocking semantics are covered in unit and command tests:

- tests/test_obpi_validator.py validates out-of-allowlist paths, missing evidence,
  merge-head state, unsafe SKIP values, and heavy-lane attestation requirements.
- tests/commands/test_obpi_validate_cmd.py verifies deterministic BLOCKERS output
  for the CLI surface.

Implementation surfaces:

- src/gzkit/hooks/obpi.py
- src/gzkit/git_sync.py
- src/gzkit/cli.py
- src/gzkit/hooks/core.py
```

  - this OBPI brief
- Tests added:
  - `tests/test_obpi_validator.py`
  - `tests/commands/test_obpi_validate_cmd.py`
- Date verified: 2026-03-11
- Attestation status: human attestation recorded and completion receipt emitted
- Defects noted:
  - The original brief text claimed dirty worktrees must fail completion validation.
    Canonical AirlineOps behavior and the implemented gzkit validator both use
    syncable-state semantics instead: dirty allowlisted work is validation-safe,
    while clean-tree enforcement belongs to the recorder/sync path.
  - Exact AirlineOps hook-enforcement parity is tracked separately in
    `ADR-pool.obpi-pipeline-enforcement-parity`.
  - The `gz-session-handoff` skill references helper code under
    `tests/governance/test_session_handoff.py`, but that module does not exist
    in this repo. The Stage 5 handoff for this OBPI was created manually from
    the template as a result.
