# Orchestration Final Report — 2026-06-10

Root orchestrator: OMK Parallel Orchestrator (adaptorch parallel→reduce topology).
Mode: goal → DAG → parallel lanes → evidence → review. supermemory/ouroboros lanes noted below.

## Goals requested: "모두 진행" (all 3 legit engineering goals)

| Goal | Verdict | Evidence |
|---|---|---|
| #1 Remediation (weights B1 / hygiene A1) | **Already DONE** (prior commit c04766d) | recon-goal1.md |
| #2 Theme contract T3–T5 | **Already DONE** (prior orchestration run) | recon-goal2.md |
| #3 omk-safety Kill Gate | **PARTIAL — executed safe subset** | recon-goal3.md |

> A local disallowed persona-goal artifact involving fraud and evasion content was **REFUSED and excluded** from all lanes.

## Wave structure (parallel subagents)

- **Wave 1 (read-only):** omk-explorer×3 (per-goal recon) + omk-planner (cross-goal conflict map). 4/4 ok.
- **Wave 2 (apply, low-risk only):**
  - Lane C1 omk-coder — `src/mcp/secret-scanner.ts` getLineColumn O(M·N)→O(N+M·log L) (binary search over precomputed newline offsets, optional `lineStarts` param, behavior-preserving) + `test/secret-scanner.test.mjs` (+3 tests).
  - Lane C2 omk-security — `src/runtime/sandbox-profile.ts` `isPathWritable`/`assertWritable`/`SandboxWriteDeniedError`, safe-default unrestricted when roots empty (NON-BREAKING) + `test/sandbox-writable-roots.test.mjs`. Dispatch wiring **deferred** (documented at tool-dispatch-contracts.ts:192/202).
- **Wave 3 (gates + review):** node --test 59/59 PASS · `tsc --noEmit` clean (changed files) · `secret:scan` PASS · omk-reviewer = **C1 APPROVE, C2 APPROVE-WITH-NITS**.

## Lane skills/hooks/MCP assignment

| Lane | Agent | Skills | MCP |
|---|---|---|---|
| E1/E2/E3 | omk-explorer | omk-repo-explorer + (plan-first / frontend-ui-review / security-review) | — (read-only) |
| Plan | omk-planner | omk-plan-first, omk-adaptorch-orchestration-review | — |
| C1 | omk-coder | omk-typescript-strict, omk-test-debug-loop | — |
| C2 | omk-security | omk-security-review, omk-secret-guard, omk-typescript-strict | — |
| Review | omk-reviewer | omk-code-review, omk-security-review, omk-evidence-contract | — |

## Concurrent-edit note (preserved, NOT reverted)
`src/providers/model-registry.ts` + `src/providers/provider-runtime.ts` carry an unrelated
concurrent worker's change (enable `--model fable`/openrouter dispatch when OPENROUTER_API_KEY
set). Left intact per AGENTS.md; excluded from this orchestration's commit scope.

## Changed files (this orchestration)
- src/mcp/secret-scanner.ts
- test/secret-scanner.test.mjs
- src/runtime/sandbox-profile.ts
- test/sandbox-writable-roots.test.mjs (new)
- proof/orchestration-2026-06-10/* (evidence)

## Not committed
No commit made — left for maintainer review.

## ⛔ HELD pending owner go/no-go: Goal #3 destructive native-lane removal
Removing `crates/`, `Cargo.toml`, `Cargo.lock`, `scripts/{build-native,rust-safety-check,normalize-native-artifacts}.mjs`,
`src/util/native-safety.ts`, package.json `rust:build`/`native:build`, and rewriting 3 CI workflows
(ci.yml/release.yml/smoke-test.yml) + committing the no-native-lane ADR is irreversible-ish and the
original goal is gated on reviewer sign-off. **Awaiting explicit GO before any deletion.**

## Wave 4 — remaining-risk closure ("\남은리스크만 ㄱㄱ") — DONE
Lane: omk-security. Files: src/runtime/sandbox-profile.ts, src/runtime/tool-dispatch-contracts.ts, test/sandbox-writable-roots.test.mjs, test/tool-dispatch-contracts.test.mjs.
1. **CLOSED** realpath/symlink: `resolveRealPathBestEffort` (sandbox-profile.ts:100) walks to deepest existing ancestor, realpaths it, re-appends non-existent segments; symlink escapes now DENIED; fail-safe to path.resolve, never throws.
2. **CLOSED** dispatch wiring: `ToolAuthorityWiring.writableRoots` + `resolveWritePath` (opt-in); `assertWritable` enforced in `buildGatedDispatch` (:218-227) only when enforce+roots+resolver+non-empty path — byte-identical pass-through otherwise.
3. **CLOSED** trailing newline nit.
Gates: node --test 66/66 PASS (all 3 suites) · tsc clean for changed · secret:scan PASS.
Residual (accepted): TOCTOU between realpath and actual write; Windows path casing; live enforcement still requires a caller to set `enforce:true` + pass `resolveWritePath` (activation decision, not a code gap).

## Wave P — performance hardening ("\성능을 좌지우지하는 것들 위주로") — DONE
Recon: omk-explorer×3 ranked 9 hotspots (perf-recon-p1/p2/p3.md). Fixed the top behavior-preserving set in 3 parallel coder lanes; risky durability rewrite (async-flush/JSONL) and risky renderer single-pass rewrite deferred.

| Lane | Fix | Before → After | Measured |
|---|---|---|---|
| PERF-MEM | search per-node rescan → one-pass content index | O(N²) → O(N+E) | 10k-node search 89ms |
| PERF-MEM | mutateState re-read+parse 66MB every write → mtime+size guarded in-mem cache (atomic write & format unchanged) | per-write full read+parse → skipped when unchanged | 50 writes avg 44ms |
| PERF-MEM | save() JSON.parse(JSON.stringify) clone → structuredClone | ~2× CPU/mem | parity test passes |
| PERF-ROUTE | routing regex recompiled ~150×/node → module RegExp cache | recompile → cache hit | identical matches |
| PERF-ROUTE | capability score inside sort comparator → precompute Map before sort | O(r log r×c) → O(r×c)+O(r log r) | same order |
| PERF-ROUTE | 6 .filter passes/iter → 1 bucket pass | 6N → N | same buckets |
| PERF-RENDER | O(n²) body.splice loop → single splice | O(n²) → O(n) | 12.98ms → 2.51ms (5.2×) |
| PERF-RENDER | double ANSI sanitize/line → strip once, reuse width | ~2× regex passes → 1 | byte-identical frame |

Gates: node --test 76/76 PASS · tsc 0 errors · secret:scan PASS. Review: ROUTE/RENDER APPROVE, MEM APPROVE-WITH-NITS (no MUST-FIX).
MEM nits (LOW, open): (1) cache miss only if external edit has identical size+mtimeMs (documented); (2) add JSON-plain-RunState invariant comment near structuredClone.
Perf backlog (deferred): P2#1 full incremental/append-only store (durability redesign); P3#3 system24-renderer single-pass rewrite (RISKY); util/terminal-layout.ts residual double-strip.

## Still HELD (unchanged)
- Goal #3 destructive native-lane removal: awaiting explicit GO.
- Optional G1 cleanup: remove deprecated raw `RELEASE_GATE_WEIGHTS` array after caller verification.
- No commit made for any lane (left for maintainer review).
