 ## Session Summary
 
-Two-day session (Apr 9–10) fully AX-driven across four releases. Starting from v1.5.3, the session produced v1.6.0 and v1.7.x (v1.7.0 through v1.7.3). The arc: build the AX constitution → audit against it → fix every gap found → ship.
+Two-day session (Apr 9–10). Goal: make vslsp fully AX-compliant — every tool, every format, every contract locked in CI. Starting from v1.5.3, shipped v1.6.0 and v1.7.0 through v1.7.3.
 
-**v1.6.0** (parallel worktree agents):
-- `docs/AX.md` — AX constitution (goal, budgets, 5 principles, tool schema standards, error message standard, CI enforcement, extension checklist)
-- `vslsp uninstall-mapper <lang>` — CLI install/uninstall symmetry
-- `tests/http.test.ts` rewrite — 4 brittle string matches → 16 real HTTP behavior tests
-
-**v1.7.0** (AX audit round 1 + round 2 + DevTeam fix loop):
-- `depth` default flipped `"full"` → `"signatures"` (AX-safe default)
-- `withDiagnosticsAxWarning()` — warns when `get_diagnostics` unfiltered > 50KB
-- `enrichError()` — ENOENT/EACCES → agent-actionable guidance in all tools
-- 13 AX ratchet tests (A1-A6, A3b, A4b, B1-B5, A5+) locked in CI
-- All tool schema descriptions updated with budget numbers and AX implications
-- `file_filter` 0-match runtime warning added
-
-**v1.7.1** — `vslsp --version` flag (CLI DX gap closed)
-
-**v1.7.2** — `toTextFormat()` + `toYamlFormat()` client-side serializers; `depth`/`file_filter`/`max_files` now apply to text and yaml formats (previously forced JSON)
-
-**CodeAudit fixes** (between v1.7.2 and v1.7.3):
-- `yamlStr()` always quotes (matches mapper binary output)
-- `walkText()` hoisted out of loop (anti-pattern fix)
-- `format` param description updated (no longer claims "ignored when filters set")
-
-**v1.7.3** — AX format parity: single-file oversized warning now uses actual serialized size for text/yaml, not JSON proxy (no false-positive warnings for text/yaml that fit the budget)
+The arc: write the AX constitution → audit every tool against it → fix every gap → audit again → fix again → ship. Two background audit agents, one DevTeam Engineer+Reviewer loop, three parallel worktree agents for v1.6.0.

 ### Build & Test Status
 
 - TypeScript: **clean** (`bun run tsc --noEmit`)
-- Unit tests: **49 pass, 0 fail** (http ×16, types ×10, store ×8, mapper ×6, typescript ×5, rust ×4)
-- E2E tests: **35 pass, 1 skip, 0 fail** (skip = RustMapper not installed)
-- Installed version: **v1.7.0** (upgrade with `install.sh --yes` once v1.7.3 CI builds)
-
-### Format Output Reference
-
-All three formats use the same `src/core/types.ts` source, `depth:"signatures"`:
+- Unit: **49 pass, 0 fail** (http×16, types×10, store×8, mapper×6, typescript×5, rust×4)
+- E2E: **35 pass, 1 skip, 0 fail** (skip = RustMapper not installed)
+- Released: **v1.7.3** — tagged and pushed, CI triggered
 
-**JSON** — machine-parseable, all fields present, AX-filtered. ~8KB for this file at signatures depth.
+### Worktree / Parallel Agent State
 
-**Text** — `[Type] signature :lineNumber // docstring`. Lowest token cost. Good for quick scan.
+Two stale worktrees from this session's v1.6.0 parallel agents — both merged into main:
 
-**YAML** — signatures always double-quoted (safe for `:` and `"` in type signatures). Medium token cost. Readable with nesting.

 ## What's Next (Optional / Future)

+1. **Go mapper** — Pattern established. Add `GoMapper` to registry, CI matrix, `install.sh`. Carried forward since v1.5.3.
 2. **Rust/TypeScript daemon** — `verify_changes` dry-run is C#-only. Requires persistent `cargo check`/`tsc` processes.
-3. **Multi-file AX truncation calibrated per format** — Currently uses JSON size as proxy (conservative, always safe). Could be calibrated to actual format size for fewer unnecessary truncations.
-4. **`vslsp install-mapper rust` 404 investigation** — CI may not be cross-compiling Rust mapper for patch releases. Check `.github/workflows/release.yml` build matrix.
+3. **Multi-file AX truncation calibrated per format** — JSON size used as proxy for text/yaml (conservative, always safe). True per-format calibration would need restructuring.
+4. **RustMapper 404 on patch releases** — Investigate `.github/workflows/release.yml` — CI may not build Rust mapper on every patch tag.
 5. **Prune stale worktrees** — `git worktree prune`

 ## Blockers & Known Issues
 
-- **RustMapper 404** — `vslsp install-mapper rust` fails with 404 on v1.7.x patch releases. Likely CI doesn't build Rust mapper on every patch. Workaround: use v1.7.0 binary for Rust mapper, or check release assets.
-- **Installed binary is v1.7.0** — upgrade with `install.sh --yes` once v1.7.3 CI releases.
-- **1 E2E test skipped** — RustMapper not installed. `vslsp install-mapper rust` to fix (once 404 resolved).
+- **RustMapper 404** — `vslsp install-mapper rust` fails with 404 on v1.7.x patches. Use v1.7.0 asset: `gh release download v1.7.0 --pattern "RustMapper-darwin-arm64" -D ~/.local/share/vslsp/rust-mapper/`
+- **Installed binary is v1.7.0** — reinstall once v1.7.3 CI publishes.
+- **1 E2E test skipped** — RustMapper not installed (see above).
 
 **Intentional keeps:**
-- Single-file oversize warns but doesn't truncate — `depth:"full"` is opt-in
-- Multi-file AX truncation uses JSON size as proxy — conservative but always safe
-- `withDiagnosticsAxWarning` warns only (no truncation) — preserves full diagnostic semantics
+- Single-file oversize warns but doesn't truncate — `depth:"full"` is opt-in, agent can use `"signatures"` instead
+- Multi-file truncation uses JSON as size proxy — always conservative (safe, never returns too much)
+- `withDiagnosticsAxWarning` warns only for diagnostics — truncating diagnostic results would change semantics
