# Session 0050.0 — Transcript

> Type: planning-and-executing
> Outcome: **SHIPPED 0.37.0** — #55 SLICE-2 (cache-lag auto-update). Merged (PR #74). #55 fully closed.

## Launch prompt

Continuation of session 0042: the operator asked "what's the best way to automate
the plugin install — can we do it at the end of a plugin coding session when a new
version is available?" → implement #55 SLICE-2 and PR it against #55.

## Plan

Reopened #55 (SLICE-2 was deferred in its decomposition). Worked in an isolated
worktree (`session-0050-cache-autoupdate`) — concurrent sessions 0035/0048/0049 in
flight, so the #56 mandate (shipped in 0042) applied; dogfooded it again.
1. `plugin-version-gap.py` — single source of truth (loaded pin vs marketplace).
2. `update-plugin.sh` — actor: marketplace update → re-check → plugin update@mkt.
3. Refactor `cache-lag-notice` to call the helper (detector + actor agree).
4. `wgl-session-finalize` plugin-repo step (origin/main ahead → run verb).
5. Docs, lint, ship, finalize.

## Pre-session state

Session 0042 (the four-issue sweep) was already finalized; 0.34.0 (SLICE-1 notice)
was live on main. The operator's follow-up reopened the auto-update question I'd
declined as SLICE-2. Reassessed: the "source-only / operator-owns-install" boundary
I cited doesn't forbid *driving the installer* — #55 itself sanctions that path —
so SLICE-2 is legitimate.

## Turn-by-turn arc

1. **Reframe.** A re-install only affects NEW sessions, so auto-updating at finalize
   makes the *next* session current — the right moment, nothing in the finishing
   session needs it.
2. **Helper + verb.** Wrote `plugin-version-gap.py` (tested: gap/parity/derived-root)
   and `update-plugin.sh` (tested `--check-only`/`--dry-run`, then a **live apply**
   confirming the `claude` CLI runs from inside a session and is idempotent).
3. **Hook refactor.** Pointed `cache-lag-notice` at the helper (single source of
   truth); verified emit-on-gap, silent-at-parity, fail-open (incl. helper-absent
   on an older cache → correctly silent).
4. **Finalize step + docs.** Added the plugin-repo-only auto-update step; updated
   CLAUDE.md (scripts list + corrected the cache-lag entry: SLICE-2 shipped, not
   declined).
5. **Ship through the churn.** PR #74; origin/main advanced to 0.36.0 mid-flight
   (a concurrent ship took my version + landed perf-fastpath/resolve-app work) —
   merged it cleanly, bumped to 0.37.0, merged PR #74.
6. **Dogfooded the new feature at this very finalize:** ran `update-plugin.sh`
   against the enabled-pin cache → it bumped the pin **0.35.0 → 0.37.0** ("updated
   … for scope user. Restart to apply"). The shipped version is now live for the
   next session — the cache-lag closed by the feature that closes it.

## Cut state (end of session)

- **Merged to main: 0.37.0** — PR #74. New: `plugin-version-gap.py`,
  `update-plugin.sh`, refactored `cache-lag-notice`, the finalize step, docs.
- **#55 closed** (Fixes in PR body) — fully done now (SLICE-1 0.34.0 + SLICE-2 0.37.0).
- `scripts/lint.sh --check-bump` clean (shellcheck skipped locally; CI inert on host).
- **Enabled pin updated to 0.37.0** by the dogfood — restart/`/clear` to load it.

## What lands on the operator's plate

- **Restart or `/clear`** to pick up 0.37.0 in your running session (the pin is
  already updated; this session keeps the 0.27.0 it loaded). After that, the
  cache-lag friction is self-healing: plugin-session finalizes auto-update going
  forward, and `cache-lag-notice` still nags for non-finalize cases.

## Deferred decisions

- **Verb gap-check vs CLI authority.** `update-plugin.sh`'s trigger compares the
  *session-loaded* version; `claude plugin update` authoritatively checks the
  *enabled pin*. They can differ (e.g. pin already bumped by another session), but
  the CLI is idempotent, so an over-trigger just reports "already at latest". Left
  as-is — simpler than reading the pin out of claude's config.
