 ## Description
 
 <!-- SECTION:DESCRIPTION:BEGIN -->
-Several core files are oversized and high-coupling (`src/main.ts`, `src/anki-integration.ts`, `src/config/service.ts`, `src/core/services/immersion-tracker-service.ts`). This task tracks phased, behavior-preserving decomposition plus guardrails and generated-launcher workflow cleanup.
+This task tracked decomposition of historically oversized/high-coupling core files (`src/main.ts`, `src/anki-integration.ts`, `src/config/service.ts`, `src/core/services/immersion-tracker-service.ts`) plus launcher generated-artifact workflow guardrails and verification.

 ## Implementation Notes
 
 <!-- SECTION:NOTES:BEGIN -->
-TASK-95 completion slice evidence: decomposed hotspot collaborators and reduced LOC across all remaining core hotspots.
+TASK-95 completion slice evidence: decomposed three non-main hotspots and reduced LOC in each targeted file.
 
 TASK-95 LOC deltas: `src/anki-integration.ts` -407 (1722 -> 1315), `src/config/service.ts` -1492 (1591 -> 99), `src/core/services/immersion-tracker-service.ts` -361 (1470 -> 1109).
 
 TASK-95 extracted collaborators: `src/anki-integration/field-grouping-merge.ts`, `src/config/{load.ts,parse.ts,warnings.ts,resolve.ts}`, `src/core/services/immersion-tracker/{types.ts,reducer.ts,queue.ts,maintenance.ts,query.ts}`.
 
 TASK-95 verification evidence: `bun run build`, `bun run test:config:dist`, `bun run test:core:dist`, `bun run check:file-budgets` completed with no failing tests.
+
+2026-02-21 finalization evidence: `src/main.ts` currently 2878 LOC; runtime fan-in guard passes at 85 import lines / 10 unique runtime paths (`bun run check:main-fanin`).
+
+Main-entrypoint scope validation for this task is fan-in/orchestration behavior, not absolute LOC target.
+
+Launcher generated artifact workflow now strictly enforced end-to-end: `scripts/verify-generated-launcher.sh` fails on stale repo-root `./subminer`; CI and release workflows verify `dist/launcher/subminer` and run the verifier script; release checksum/upload paths updated to `dist/launcher/subminer`.
+
+Docs policy updated in `docs/development.md` and `docs/installation.md` to state repo-root `./subminer` is stale/unsupported and generated path must be `dist/launcher/subminer`.
+
+Final verification gate passed: `bun run build && bun run test:config:dist && bun run test:core:dist && bun run check:file-budgets && bun run check:main-fanin`.
+
+TASK-85 AC/DoD ownership map:
+- AC#1 (`src/main.ts` orchestration-focused runtime domains): `TASK-94` (primary), `TASK-71` (supporting predecessor)
+- AC#2 (`src/anki-integration.ts` facade + collaborators): `TASK-95`
+- AC#3 (config + immersion decomposition with no regressions): `TASK-95`
+- AC#4 (generated launcher ownership/workflow documented + enforced): `TASK-85` parent finalization evidence
+- AC#5 (full build + config/core tests pass): shared verification evidence in `TASK-95`, `TASK-94`, and final TASK-85 gate
+- DoD#1 (plan executed/decomposed): `TASK-94` + `TASK-95`
+- DoD#2 (regression coverage for extracted seams): `TASK-94` + `TASK-95`
+- DoD#3 (docs updated): `TASK-71` architecture docs + `TASK-85` launcher workflow docs
+
+Remaining Scope (ordered):
+1. Execution scope: none (all TASK-85 AC/DoD complete).
+2. Process hygiene: TASK-93 closure synchronization and provenance note alignment.

+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Closed remaining TASK-85 scope by enforcing generated launcher ownership (`dist/launcher/subminer`) across local verification, CI, release packaging/checksums, and contributor docs. Revalidated refactor integrity with full build + config/core test gates plus maintainability guardrails (`check:file-budgets`, `check:main-fanin`) and marked parent AC/DoD complete.
