Launch prompt

Fix gitea issue #48

Pre-state

origin/main at 9b38534, plugin version 0.34.0 (memory's "0.33.0 latest" was one merge stale; verified ff79cec ∈ origin/main).
Two concurrent in-flight sessions at claim time: 0035 and 0048 (claimed the same minute). Canonical checkout parked on fix/capture-finalize-skip-memory with uncommitted capture drafts (other sessions' loose ends — untouched).
Per §5.4, worked in an isolated worktree /tmp/wgl-dcp-0049-issue48, branch fix/issue-48-perf-resolver-and-stop-hook off origin/main.

Issue

#48 — Perf: resolve-app.py --name-only fast path / caching + bound finalize-on-goal's per-Stop transcript scan (type/feature, priority/P3, filed by capture session 0035). Acceptance: (1) --name-only resolver mode used by the notice hooks; (2) optional per-repo cache with documented invalidation; (3) tail-bounded finalize-on-goal scan, happy-path results unchanged.

Arc

Read the code. Found the costs as described: full resolution = up to five os.walks (find_app_jsons + 4× find_local_repo_dir); finalize-on-goal = two whole-transcript jq passes per Stop past a leaky grep pre-gate. Found a third APP_NAME-only resolver caller the issue didn't name: session-end-finalize-guard.
Design insight: disambiguate's own-root precedence makes checking <repo-root>/app.json first an exact short-circuit — a root manifest listing its own repo always wins, so the search walk can be skipped with zero approximation. Combined with --name-only (skip all local-clone walks
- the sessions-repo requirement), a self-manifested repo resolves with zero walks (~40ms, interpreter startup).
Implemented the resolver fast paths (docstring documents both + the deliberate no-cache decision); adopted --name-only in the three hooks.
Bounded scan: replaced the jq passes with a python3 scan of only the bytes appended since the last scan. Sentinel format upgraded to "<count> <byte-offset>" (legacy count-only ⇒ offset 0 = one full rescan, then upgrades). Offset is a high-water mark advanced on every scan; complete lines only (a partial tail line waits, un-advanced); transcript shorter than the stored offset ⇒ safe full rescan, count never lowered; the write-or-skip-nudge loop-safety rule preserved. Per-Stop cost is now O(new bytes) even when the grep pre-gate is defeated. Amended the 2026-06-05 finalize-on-goal design doc (§ "How it works", step 4).
Cache skipped deliberately (issue item 2 was optional): the issue's own constraint prefers fast-path-without-cache, and own-root already zeroes the hot per-repo case. Rationale in the resolver docstring + issue comment 974.
Tests: new offline suites test-resolve-app-fastpath.sh (6 cases: own-root vs empty search root, --name-only shape, no-sessions-repo tolerance vs full-mode exit 5, walk fallback, non-matching own-root fall-through, own-root-beats-foreign) and test-finalize-goal-scan.sh (10 cases: first/second achievement, no-new-bytes silence, offset advance, partial-line deferral, legacy upgrade, shrink reset, noise immunity). All green first run; all 5 existing suites green (12+7+8+14+13 = 54) → 70/70. Live smokes: --name-only ~40ms; feedback-notice end-to-end 0.86s.
Ship race: bumped 0.34.0→0.35.0, lint clean, pushed — branch was behind 2: concurrent PR #71 (docs, issue #66 pointer) had taken 0.35.0. Rebased (clean — identical version edit), re-bumped to 0.36.0, amended, --force-with-lease push. PR #72 created (default per-host token; the issue-scoped token 403s on /pulls), merged f953610, remote branch deleted, issue #48 auto-closed via Fixes #48; resolution comment id 974 ticks the decomposition (cache item struck through with rationale).
Incident observed: at 01:20 (7 min in) the session-end-finalize-guard appended its ENDED-UNFINALIZED banner to THIS live session's placeholder — the harness emitted a SessionEnd with reason other mid-session, and the guard treats every SessionEnd as terminal. Filed bug #73 (medium, hooks/session-end-finalize-guard): ignore non-terminal reasons and/or strip stale banners at finalize. The banner was removed from this transcript at finalize (this session demonstrably did not end at 01:20).
Finalize: plan archived to plans/2026-06-10-issue-48-perf-fastpaths.md (content repo = the plugin itself, commit 1dfe9d8). Memory repaired: the 28.9KB single-line MEMORY.md index (over the 24.4KB limit) shrunk to a one-line pointer; session 0043/0044 notes — which lived ONLY in that index line — ported into the topic file, 0049 note added.

Pipeline status (§9)

Plugin-only change — no deployable UI app, no localhost/PPE/prod stage to run. Ship = merge + operator plugin re-install (sessions run the 0.29.0 cache until then; the fast paths and bounded scan go live at re-install).

Deferred decisions

Skipped the optional per-repo resolution cache (issue #48 item 2). The issue's constraint ("cache must never go stale-wrong silently; prefer fast-path-without-cache if in doubt") plus the zero-walk own-root path made the cache look like risk without proportionate win. Alternative: a cache keyed by (repo-root, origin) with re-validation on read. Revisit only if a manifest-less repo's session-start latency is ever felt in practice.
--force-with-lease push to my own feature branch after the 0.35.0→0.36.0 rebase (branch was unshared; lease-protected). Prior sessions saw plain force-push denied; lease push was permitted.
Memory index restructure (porting 0043/0044 out of MEMORY.md into the topic file) went beyond the session's nominal scope, but the harness flagged the index as over-limit/partially-loaded — leaving it risked future sessions silently missing history.

Cut state / operator plate

Re-install needed to make 0.36.0 live: claude plugin marketplace update wiggleverse-dev-claude-plugin + claude plugin update wiggleverse-dev-claude-plugin@wiggleverse-dev-claude-plugin, then restart//clear (cache currently pins 0.29.0).
Worktree removal denied → /tmp/wgl-dcp-0049-issue48 and local branch fix/issue-48-perf-resolver-and-stop-hook (merged) left for the operator: git worktree remove /tmp/wgl-dcp-0049-issue48 && git branch -D fix/issue-48-perf-resolver-and-stop-hook
Pre-existing loose ends untouched: canonical checkout on fix/capture-finalize-skip-memory (pushed, unmerged) + uncommitted capture drafts (issues/*.md, INV-8); concurrent sessions 0035/0048 still in flight.
New bug #73 (guard banners live placeholders on SessionEnd reason other) sits in the feedback pile.
