   - Product commit: `fc68cf295131d8f73556bef59fdeae61239a649e`; source and product trees are exact-equal at `5c14e92224e8441d18a983dd7099cd6d76f83e85` before this Integration Documentation Gate removes the duplicate foreign task record.
   - Delivered the Main-only closed Web Search client, bounded same-operation reconciliation, code-owned adapter, and the minimal generic billing/conversation/Registry support for `not_started` and Main-only `receipt_unavailable`. The adapter uses the MLW-01 admission helper and trusted project/request identity; no composition, Renderer, Pi, Package Store/effective resolver, Provider authority, or server path changed.
   - Final source review aligned source title/URL bounds with the frozen Server DTO and preserved both MLW-01 typed admission failures. The clean source branch retains its complete task record; integration evidence is consolidated here.
+- MLW-03 source task `20260901-web-search-mlw03-composition-d9f5b3e2` was integrated from exact frontier `68cb2e73beb17d5041198d020aaa7b2884124950`.
+  - Source commit: `52f6a0b148403c822a09880467f81416a181b259` (sole parent `68cb2e73beb17d5041198d020aaa7b2884124950`).
+  - Product commit: `60e6a8eeb35431b0f1fb569af4d1502683f16317`; source and product trees are exact-equal at `d570c40f2ad315c8a314f831fb4337300ae28fc2` before this Integration Documentation Gate removes the duplicate foreign task record.
+  - Delivered production composition registration, the dynamic Web Search parent/child/current-authority proof, a generic closed billing-status timeline projection, package-main-reachable route/receipt proof with Provider-authority exclusion, and current README documentation. No Web Search payload-specific Renderer or static tool allowlist was added.
+  - The clean source branch retains its complete task record. This coordinator checkpoint removes only the duplicate cherry-picked copy and records the accepted facts in canonical project memory.

 - MLW-02 final focused suite passed `3 files / 35 tests`; adjacent hosted admission, Game Resource, Registry, conversation, Marketplace-client, and timeline regression passed `11 files / 114 tests`.
 - MLW-02 full unit suite passed `214 files / 1748 tests`, with two staged-runtime skips; pressure passed `1/1`. Typecheck, owned lint, full lint (zero errors and the same five existing warnings), and Vite Renderer/Main/Preload/utility builds passed.
 - MLW-02 diff, project-docs, document-drift, sole-parent, clean-worktree, and `READY_FOR_INTEGRATION` gates passed. No live Provider call or production activation occurred.
+- MLW-03 TDD started with four exact focused failures and finished with 4 files / 40 tests passed; the adjacent Web Search/admission/composition/lifecycle/Pi/timeline/artifact suite passed 10 files / 82 tests.
+- MLW-03 full unit suite passed 214 files / 1,751 tests with two staged-runtime skips; pressure passed 1/1. Typecheck, scoped lint, full lint (zero errors and the unchanged five warnings), Vite builds, Electron Windows 6/6, and target Marketplace/Project Plugins/Skill E2E 4/4 passed.
+- Clean source HEAD Windows packaging and verification passed. `verify:artifact:win` embedded exact commit `52f6a0b148403c822a09880467f81416a181b259`; installer size was 208,252,221 bytes with SHA-256 `2D027DB5BE00336F1EB45D882519F971EB791014A1930C5FBED93FE6B15B6303`. `verify:artifact:pi` passed the real app.asar Web Search route/receipt/provider-authority proof; inherited Pi cross-platform/real-provider waivers remain unchanged.
 
 ## Follow-ups
 
-- Start MLW-03 only from the clean post-MLW-02 coordinator frontier. MLW-03 owns composition, the generic timeline billing projection, dynamic tool/package proof, README, and necessary focused/E2E evidence; it must not reopen MLW-01/02 authority.
-- Keep the live OpenAI XWS-01 group and production activation closed pending explicit external inputs and user authorization.
+- Run fixed-range Standards and Spec review from client base `0a86ec825a5803bf7e037d3b23c39be23238c43d` through the clean post-MLW-03 documentation frontier; use one remediation owner only if either axis reports an actionable finding.
+- Keep real PostgreSQL, the live paid OpenAI XWS-01 group, and production activation closed pending their explicit external inputs and user authorization.
