#3 Fuzzy patch applier: new pure fuzzy-match.ts (locateMatch, exact→trim→ unicode-canon→Levenshtein≥0.66, refuse-on-ambiguous) wired into pending_changes applyOne/rewindOne so local-model whitespace/unicode drift in old_string no longer loses the edit. #4 Worktree checkpoint + conversation-trim: checkpoints table + checkpoints.ts (shadow-commit of tracked+untracked into refs/boocode/checkpoints, hooked into the 3 external-agent dispatcher paths) + POST restore route (reset --hard + clean -fd -> transcript trim -> backend-session reset) + "Restore to here" UI. Built by 3 parallel agents; DB-integration testing caught a created_at self-deletion bug. Coder suite 234 passing; server+coder build + web tsc clean. Builds on v2.7.0-mit. openspec write-edit-robustness. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
openspec
Per-batch documentation convention adopted v1.13.15-openspec.
Agent entry point: AGENTS.md at repo root. Architecture diagram: docs/ARCHITECTURE.md.
Lift source: Fission-AI/OpenSpec directory layout. No CLI dependency — just the folder shape. Full OpenSpec lifecycle adoption is a future v1.14+ batch.

Conventions
- Slugs are lowercase-hyphenated derived from the batch title
(e.g.
v1-13-10-per-tool-cost,file-attachments-v3-5). - Already-shipped pre-v1.13.15 batches live in
changes/archived/as single-file snapshots. They were not split into proposal/tasks because the work was already complete; archiving preserves git history. - New v1.13.15+ batches should land directly in
changes/<slug>/proposal.md(+ tasks.md, + design.md when applicable). proposal.mdcarries the "Why" and scope.tasks.mdis the action list (numbered or checkbox).design.mdis for non-trivial architectural decisions worth recording separately.- A canonical dispatch brief (matching the v1.13.9 / v1.13.10 format) is most naturally split as proposal.md (Where we are, Why this matters, rationale sections) + tasks.md (Scope items, Build + smoke) + design.md (Attribution model, Filtering, Canonical mapping).
