Phase 8 of v2.0. Final hardening pass before production tag.
Path-guard fuzz suite (34 tests): traversal attacks (../ all depths,
encoded %2e%2e, null bytes, absolute escapes, prefix-without-separator,
backslash), secret-file deny list (.env, *.pem, id_rsa*, *.key,
credentials.json, *.kdbx, .netrc), valid-path positives, edge cases
(empty, whitespace, very long, triple-dot, multiple slashes).
write_guard.ts hardened: added null-byte rejection and whitespace-only
rejection (previously only checked empty string).
Pending-changes integration test skeleton: 4 tests covering the full
queue→apply→rewind cycle against a real DB + filesystem. Gated on
DATABASE_URL via describe.runIf (same pattern as apps/server's
tool_cost_stats.test.ts). Skips cleanly when unset.
57 tests passing (23 existing + 34 fuzz), 4 integration skipped.
All builds clean. All services healthy.

Phase 2 of v2.0. BooCoder is now a functional write-capable chatbot.
Write-path guard: resolveWritePath() uses resolve() (no realpath — files may
not exist for creates) + prefix-check + secret-file deny list (.env, *.pem,
id_rsa*, etc.). 23 unit tests cover traversal attacks.
Pending-changes service: queueEdit/Create/Delete → applyOne/All →
rejectOne/All → rewindOne. Edit diffs stored as JSON {old, new}. All writes
queue before touching disk; apply re-validates the path guard.
5 write tools: edit_file, create_file, delete_file, apply_pending, rewind.
Registered alongside 25 read-only tools from BooChat (30 total, alpha-sorted).
Write tools use a module-level inference context for sql+sessionId injection.
Inference loop via workspace dependency: apps/coder imports
createInferenceRunner, createBroker, ALL_TOOLS from @boocode/server (dist/).
apps/server gains declaration: true + exports map with typed subpath entries.
No code duplication — one inference engine shared by both apps.
API routes: POST /api/sessions/:id/messages (user msg → inference), POST stop,
GET/POST pending-changes CRUD (5 endpoints), WebSocket session streaming.
Dockerfile updated to build apps/server first (coder depends on its .d.ts).
Health endpoint reports tool count: {"ok":true,"db":true,"tools":30}.
