# Phase 34: Version-Change Changelog — Verification Report

**Phase Goal (per ROADMAP.md, post-D-12 amendment):** When a user's installed `spt` plugin version changes underneath them, the next Stop hook in an spt-bearing session surfaces an old→new changelog notice sourced from compiled-in `CARGO_PKG_VERSION` against an `$SPT_HOME/last-seen-version.json` sentinel — without firing on first install, without colliding with the SessionStart auto-pick (AUTO-03), and without racing the binary handoff (Phase 18.4/18.5).

**Verified:** 2026-05-17
**Status:** PASS — phase + hotfix bundle complete; milestone v1.7.1 ready for completion gate.
**Re-verification:** No — initial verification of Phase 34 final state.

Lib test `read_sentinel_returns_some_on_happy_path` passes.                                                                                                                                     |
| VERS-02 | Stop hook in `src/owl/hook_idle.rs` gated on perch resolution; compares `env!("CARGO_PKG_VERSION")` against sentinel             | ✓ VERIFIED | `hook_idle.rs:26` imports `version_changelog::{self, VersionPrompt}`; call at line 74 happens AFTER perch resolution (lines 42-49) and AFTER `OWL_ECHO_COMMUNE` + `stop_hook_active` guards (lines 61-64). `version_changelog::current_version()` uses `env!("CARGO_PKG_VERSION")` with a debug-only `SPT_OVERRIDE_PKG_VERSION` test seam (release-safe).      |
| VERS-03 | First-install (sentinel missing) silently writes current; NO prompt                                                              | ✓ VERIFIED | `maybe_emit_version_change_block` lines 437-443 handles `None` by writing the current version + returning `VersionPrompt::NotEmitted` (no emission). Integration test `first_install_silent_writes_sentinel` passes.                                                                                                                                            |
| VERS-04 | AskUserQuestion with four options; question text includes `step_count` when > 1                                                  | ✓ VERIFIED (amended by hotfix 6om) | Plan 03 commit `dbc24ce` wired the four-option AUQ wording into `build_block_reason`; integration test `block_reason_matches_reference_invariants` asserts all four labels. **Amendment**: hotfix 260517-6om dropped `Remind me later` to a 3-option AUQ (CHANGELOG v1.10.12 entry — infinite-loop pathology). User-decided remediation; not a regression of the requirement intent. |
| VERS-05 | Sentinel atomically rewritten via `atomic_write_string` so prompt does not re-fire                                               | ✓ VERIFIED | `write_sentinel` at version_changelog.rs:112 uses `owlery::atomic_write_string` (tmp + rename); pre-write happens at line 506 BEFORE emission. Integration test `sentinel_equal_no_emit` confirms no re-fire when sentinel matches.                                                                                                                              |
| VERS-06 | Multi-version skip shares 4-option AUQ with single-step; `Yes, full changelog` renders interim H2 sections verbatim              | ✓ VERIFIED | `parse_changelog` + `sections_between` (exclusive low, inclusive high) at lines 206-260. Lib test `sections_between_filters_exclusive_low_inclusive_high` passes. Integration test `multi_step_mismatch_emits_block_with_step_count` asserts `<step_count>5</step_count>` for v1.10.5 → v1.10.10.                                                                |

| VERS-08 | VERS-04 (Stop) and AUTO-03 (SessionStart) coexist by hook separation; no allow-list reconciliation                               | ✓ VERIFIED | `hook_idle.rs` (Stop) wires `maybe_emit_version_change_block`; `plugin_session_start.rs` (SessionStart, Phase 33) wires AUTO-03's `emit_auto_pick`. Two distinct hook entry points; no shared dispatch path. Confirmed by `Grep maybe_emit_version` returning hits only in `hook_idle.rs`, `mod.rs`, `version_changelog.rs`, `hook_output.rs`.                  |
| VERS-09 | Single write site at top of `hook_idle.rs::run()` after perch resolution + OWL_ECHO_COMMUNE guard; atomic via `atomic_write_string` | ✓ VERIFIED | Sentinel WRITE-call site grep confirms only one production write path (`write_sentinel` at version_changelog.rs:112). `hook_idle.rs::run()` ordering: parse stdin (31) → resolve session (33-36) → resolve perch (42-49) → OWL_ECHO_COMMUNE + stop_hook_active guard (61-64) → `maybe_emit_version_change_block` (74-77) → `set_idle_ready` (85) → spawn_echo_commune (88). Ordering matches D-05/D-12 amendment verbatim. |

### Full-suite test note (informational)

Running `cargo test --lib` (full suite, parallel) produces 21 failures in unrelated modules: `live::commune`, `live::context`, `live::wrapper::lifecycle`, `live::wrapper::orphan`, `owl::cleanup`, `owl::resume`, `common::owlery::is_perch_online_false_for_dead_pid`. When run in isolation (e.g., `cargo test --lib owl::hook_idle`), every Phase 34 test passes. The 21 failing tests are in code paths owned by Phases 18 / 28 / 30 / 32 and concern filesystem race conditions under parallel test execution (PID-reuse, `info.cwd` write race, signoff cursor race). **None of the failures cross into Phase 34's surface**, and all 61 Phase 34 tests (45 lib + 16 integration) pass in both isolated and full-suite runs. Flag for separate cleanup; not a Phase 34 blocker.

## Probe Execution

No conventional probes (no `scripts/*/tests/probe-*.sh`) declared for this phase. Probe-equivalent verification is the cargo test suite documented above.

## Verdict

**PASS** — Phase 34 (with hotfixes 260517-6om + 260517-n4b folded in) delivers all 9 VERS requirements, all 6 ROADMAP success criteria, and both post-execution hotfix surfaces. CHANGELOG.md is curated through v1.10.13; the curation gate enforces this discipline for all future bumps; the owl-message transport + info-priority routing land the prompt as a calm informational message rather than a high-priority Stop block.

**Phase 34 is sealed.** STATE.md may be flipped to **4/4 phases complete**; milestone v1.7.1 Seamlessification II is **ready for `/gsd-complete-milestone`**.

### Recommended next action

1. **Before running `/gsd-complete-milestone`**: commit the untracked `.planning/quick/260517-n4b-version-change-uat-defect-cleanup/` ledger directory (PLAN + SUMMARY) so the n4b quick task is permanentized in git history alongside its code commits.
2. **Update STATE.md**: flip Phase 34 row from `1/3 In Progress` to `3/3 Complete` (the ROADMAP.md table at line 708 currently shows `1/3 In Progress` — should be `3/3 Complete` with date `2026-05-17`). Update milestone-progress counters.
3. **Run `/gsd-complete-milestone v1.7.1`** to seal the milestone.
4. **Optional follow-up quick task**: investigate the 21 parallel-run test failures (live::commune, live::context, live::wrapper, owl::cleanup, owl::resume) — these pre-date Phase 34 but are surfacing under the current test corpus.
