## Current State Summary

Move 2 of the get-out-of-jail recovery plan (`docs/governance/get-out-of-jail-plan-2026-05-23.md`) is mid-flight. The promote phase landed cleanly: `ADR-pool.focused-context-loader` was rewritten to the preferred `**slug** — narrative` form, promoted to `ADR-0.28.0-focused-context-loader` (eval gate cleared 3.7/4.0 GO after Intent/Decision/Alternatives/Architectural-Alignment strengthening), and both OBPI briefs were hardened with 8 + 5 REQ-derived semantic assertions plus real Allowed Paths and concrete Demo invocations.

OBPI-0.28.0-01-context-core is implementation-complete (TDD GREEN, lint clean, type-check clean, smoke-test against `ADR-0.0.3` produces 82.7 KB Markdown payload). `gz context <ADR-ID>` is registered as a new top-level CLI verb. The `--slim` flag is NOT yet wired (defer to OBPI-02 per the brief's REQ-09 boundary), but the `slim=False` parameter is plumbed through `build_context_payload` so OBPI-02's work is a small additive change. Nothing is committed yet; the working tree carries the OBPI-01 implementation, both hardened briefs, the strengthened ADR body, and the rewritten pool ADR.

GHI #527 was filed during this session for the pre-existing `ADR-0.0.9-state-doctrine-source-of-truth` defect (Validated status enum + missing Decomposition Scorecard / Checklist / Evidence sections) surfaced incidentally by `gz validate --documents`. It is cross-linked as a sibling-cut of GHI #524 and recovery-deferred per anti-temptation #6.

## Important Context

- **`gz context` is a top-level verb, not `gz adr context`.** Registered in `src/gzkit/cli/parser_artifacts.py::_register_context_parser` alongside `_register_justify_parser` (same shape: single positional, top-level command).
- **Renderer is factored for OBPI-02.** `context_cmd(adr, *, slim=False)` → `build_context_payload(adr_file, project_root, *, slim=False)`. The `if not slim:` branch already gates the governance-rules section. OBPI-02 only needs to (a) add `--slim` to the parser, (b) thread `a.slim` through the lambda, (c) add the REQ-02-01..05 tests.
- **`@covers` discovery uses `gzkit.traceability.scan_test_tree`** — REQ ID lives on `record.target.identifier`, test file path on `record.evidence_path`. Records are filtered by `REQ-{adr-semver}-` prefix derived from the ADR stem.
- **`resolve_adr_file` only takes (project_root, config, adr).** The earlier call `ensure_initialized(project_root)` was wrong — `ensure_initialized()` takes zero arguments and returns the loaded config. Test harness `_quick_init` creates a workspace with `paths.adrs = "design/adr"` (NOT `docs/design/adr`); tests must use `Path(GzkitConfig.load(Path('.gzkit.json')).paths.adrs)` for the seeded ADR root.
- **Handler return values are discarded by `gzkit.cli.main`.** Non-zero exits must raise `SystemExit(code)` after writing the `BLOCKERS:` line to stderr — `return 1` falls through to `main`'s `else: return 0` clause.
- **Eval gate strengthening hits structural patterns, not prose quality.** The `gz adr evaluate` heuristic checks: numbered Decision items, "rationale"/"because" language, ≥3 Alternatives Considered, source-file path references (`src/gzkit/...`), exemplar language, anti-pattern language. The strengthened ADR body satisfies all of these mechanically.
- **OBPI Allowed Paths overlap is structurally honest here.** Both OBPI-01 and OBPI-02 touch `src/gzkit/commands/context_cmd.py`, `src/gzkit/cli/parser_artifacts.py`, `tests/commands/test_context_cmd.py`, and `docs/user/manpages/context.md` because OBPI-02 is a subtractive increment over OBPI-01's renderer. The eval scorecard flagged this 3/4 ("paths overlap"); the brief documents the overlap as deliberate.

## Decisions Made

- **Decision:** Promote `focused-context-loader` to semver `0.28.0` rather than skipping.
  **Rationale:** Last shipped feature is `0.27.1`; `0.28.0` is the next available. Move 2 of the recovery plan binds this slot.
  **Alternatives rejected:** Wait until OBPI-01 + 02 both implement before promoting (would block the eval gate from giving real feedback on the briefs); promote to a later semver (would leave a coherence gap with `pyproject.toml`).

- **Decision:** Rewrite the pool ADR's `## Target Scope` from legacy narrative-only bullets to the `**slug** — narrative` form before promotion.
  **Rationale:** The legacy form produced 3 narrative-leaking OBPIs (`OBPI-0.28.0-01-new-cli-command-gz-context-adr-id-that-outputs`, …) instead of the 2 OBPIs the recovery plan calls for. The promoter resolves slugs deterministically from the bold-prefix convention.
  **Alternatives rejected:** Accept 3 OBPIs and merge later (creates a brief-shape remediation chore); use a `## Proposed OBPI Decomposition` table (richer than needed for a 2-OBPI scope).

- **Decision:** Defer the `--slim` CLI flag to OBPI-02; ship only the `slim=False` parameter plumbing in OBPI-01.
  **Rationale:** OBPI-01 REQ-9 explicitly requires the renderer be factored so `--slim` is subtractive; landing the flag in OBPI-01 would bundle OBPI-02 scope. The renderer factoring satisfies the REQ without crossing the OBPI boundary.
  **Alternatives rejected:** Land `--slim` in OBPI-01 (scope creep); skip parameter plumbing entirely (would force OBPI-02 to refactor the renderer instead of extending it).

- **Decision:** Use `SystemExit(1)` after `BLOCKERS:` stderr write for unresolvable ADR IDs.
  **Rationale:** `gzkit.cli.main` discards handler return values. Raising `SystemExit` is the only path that propagates an exit code from the command layer; `raise GzCliError` would render via `console.print(f"[red]{exc}[/red]")` and not produce the `BLOCKERS:`-prefixed stderr line the rest of gzkit follows.
  **Alternatives rejected:** Return `1` (does nothing); raise `GzCliError` (loses the BLOCKERS prefix convention).

- **Decision:** File GHI #527 for `ADR-0.0.9` missing-sections defect rather than fixing in-flight.
  **Rationale:** Recovery-plan anti-temptation #6 forbids in-flight defect fixes during the 14-day recovery. Sibling-cut of #524 (same root-cause class) cross-linked at authoring time per `ghi-author` Step 0.
  **Alternatives rejected:** Fix in-flight (violates recovery boundary); leave untracked (violates Prime Directive #6 — every defect must be trackable).

## Immediate Next Steps

1. **Run `uv run gz obpi pipeline OBPI-0.28.0-01-context-core`** to drive OBPI-01 through verify → ceremony → guarded git-sync → completion. Stage 5 will gate on Gate-5 attestation (universal per ADR-0.0.36). The pipeline-orchestrator persona owns this; do not hand-edit ledger entries.

2. **Author `docs/user/manpages/context.md`** as part of the OBPI-01 ceremony — Synopsis, Options, Examples, Exit Codes. Required for `gz cli audit` coverage of the new verb (CLI-alignment rule: `tool → skill → runbook`). Brief's Allowed Paths already include this file.

3. **Implement OBPI-0.28.0-02-context-slim** after OBPI-01 lands. Three small edits: (a) add `--slim` flag to `_register_context_parser` in `src/gzkit/cli/parser_artifacts.py`, (b) pass `slim=a.slim` through the lambda, (c) add `REQ-0.28.0-02-01..05` tests to `tests/commands/test_context_cmd.py` (one new test class is fine — keeps OBPI-01's class intact for the byte-parity regression assertion in REQ-02-05).

4. **Update `.gzkit/skills/gz-context/SKILL.md`** to point at `gz context <ADR-ID>` as its primary entry. This is the "wire router" task — the namespace router shipped under Move 1 but currently has no payload to route to.

5. **Run `uv run gz obpi pipeline OBPI-0.28.0-02-context-slim`** then `gz-patch-release` for `v0.28.0`. v0.28.0 release notes anchor to Move 2 of the recovery plan.

## Pending Work / Open Loops

- **No `gz handoff` CLI verb exists.** The `gz-session-handoff` skill body references Python helpers under `tests/governance/test_session_handoff` (test module as runtime API — awkward). Filing this as an enhancement is in scope for post-recovery triage, not now.
- **Two handoff location conventions in tension.** This document follows the skill's documented procedure (`{ADR-package}/handoffs/`). The session-orientation hook reads `.gzkit/handoffs/` for its "Most-recent handoff" report. Recent practice (Move 1's OBPI-0.27.0-01/02/03 handoffs) used `.gzkit/handoffs/` freeform. The dual-location pattern is a real ergonomics issue worth filing as enhancement after recovery.
- **GHI #527** open; recovery-deferred. Sibling-cut of #524. Both will close after Move 5's closeout-on-spine ships and the backfill sweep catches the foundation/ tier.
- **Move 2 not yet committed.** Working tree carries: ADR-0.28.0 body (strengthened), pool ADR (Superseded), OBPI-01 + OBPI-02 briefs (hardened), `src/gzkit/commands/context_cmd.py` (new), `src/gzkit/cli/parser_artifacts.py` (registered context verb), `tests/commands/test_context_cmd.py` (new). The pipeline ceremony will commit per-OBPI matching Move 1's pattern.
- **Manpage authoring (`docs/user/manpages/context.md`)** — not yet started; required by `gz cli audit` after the verb lands.
