# S50 (2026-06-07) — Harness 1·2·3 verified-runtime closeout + AS-10 autonomous-write finding

> **Type:** infra-finish (governance, no product code, CI-skip). HMW-mode ON. Continues S49 (Harness 1·2·3 adopt).
> **Test:** 181 PASS (58 Domain + 123 Infra) unchanged — 0 `.cs` touched.

## TL;DR
S49 left the Harness 1·2·3 adoption at **executed-file, verified-runtime PENDING CLI restart**. S50 = post-restart verification of all 3 parts → **fully verified-runtime**. Then session-end surfaced a real **AS-10 containment finding**: monitor sub(s) autonomously wrote canonical/agent-memory files; em-main git-diff commit-gate caught + verified all (accurate, no corruption, chunk 2415) → adopted per AS-10 keep-if-correct + logged E-006.

## S49 milestone closure (the "🔴 NEXT-FIRST")
- **(a) H1+H2 monitor subs verified-runtime** — `/session-start` spawned `tooling-auditor` (H1) + `harvest-curator` (H2) for the Phase 2.1.1 RE-REPORT. Both loaded + ran post-restart → verified-runtime CONFIRMED.
  - H1 caught **3 doc-freshness drifts** → em main patched: plugin `15→18` (`agents/README.md:157`), skill-index `31→43` mig + `49→57` gotcha (`skills/README.md:20,90` — **missed by S44 monthly audit**, index file not on its checklist), verified-runtime markers.
  - H2 harvest 🟢 clean: 16 user-memory pointers ↔ 16 files, 0 orphan / 0 byte / 0 corruption.
- **(b) H2 wave-mode verified-runtime** — wave-run `h2-verify` (Workflow Run `wf_b7e4d6ef-787`, 2-agent: investigator-codebase read-only + test-specialist write-direct). **B6 isolation HELD**: post-P2 `git status` = baseline only (0 canonical/agent-memory leak at wave instant), sub-MDs gitignored (`.gitignore:93`), **chunk-count 2415→2415** (0 rogue RAG write). B4 both-paths exercised (write-direct + read-only-scribe).
  - **Bonus:** gotcha #57 confirmed open + exact coords — `LeaveTypeConfiguration.cs:19` + `ShiftPatternConfiguration.cs:19` bare `.IsUnique()` vs fixed `HolidayConfiguration.cs:18 .HasFilter("[IsDeleted] = 0")`; test template `HrmConfigHolidayTests.cs:180-197`.
- **(c) H3 email send-path verified-runtime (SE-side)** — `/send-email ai_infra` handshake → `broadcasts/outbox/ai_infra/2026-06-07-se-to-ai_infra-harness-123-handshake.md`, body SHA256 `c9656c19…` self-verified MATCH + `_index.md` OUTBOUND logged. **2-way byte-identical = pending AI_INFRA `/check-email se`** (their step; `ai_infra/outbox/se/` empty so SE receive-path untested).

## Rig fact (cross-cutting, both wave subs + both monitors)
Bash tool routes to **`/usr/bin/bash`, NOT PowerShell**, despite `env=PowerShell`. Read-only/Bash-only subs MUST use POSIX (`git ls-files`/`grep`/`ls`) — `Get-ChildItem`/`Select-String`/`Test-Path` fail (exit 2/127). Also: chunk-count must be verified via **RAG MCP `list_projects`**, NOT a shell `curl localhost:6333` (MCP points at a different Qdrant host → false "not found").

## ⚠️ AS-10 finding — autonomous monitor write at session-end (E-006)
At `/session-end`, `git status` showed **14 modified files**, but em-main had only edited ~7. The remainder — `error-ledger.md` (2 guard promotions + #57 coords), 3 `adap-reports` (nac→verified-runtime), 4 `agent-memory/*` (S50 Recent-activity), and parts of `STATUS.md` (Recently-Done S50 block + In-Progress flip + RAG-line reconcile) — were written by a **non-em-main actor** (mtimes 00:00–00:05 = session-end monitor window; the 2 INFORM-only monitors were briefed propose-only and reported "wrote nothing").
- **Containment HELD:** em-main `git diff` surfaced every changed line → reviewed all → **accurate, benign, correctly-placed, 0 mojibake, chunk 2415** (no RAG corruption). Adopted per AS-10 "keep if correct" under single-writer commit-gate authority.
- **Process gap flagged:** propose-only monitors should not write canonical files (B3 single-writer). Provenance not definitively attributable, but the write happened (G-015 residual Bash channel). RECOMMEND anh/AI_INFRA review monitor tool-grants or add a session-end tracked-path write-guard. Self-report Fidelity gap noted (escalate reviewer if recurs).

## Files touched (14, docs/infra only — CI-skip)
STATUS · HANDOFF · agents/README · skills/README · error-ledger · 3 adap-reports · 4 agent-memory · broadcasts/_index + handshake. Wave-folder `.claude/workflows/wave-h2-verify/` gitignored (harvested by H2 B5 → disposable).

## Next (anh pick)
