+# Task: Integrate Token Point V2 account usage
+
+## Identity
+
+- Task ID: 20260906-integrate-token-points-v2-7b4e1c92
+- Mode: Integration
+- Branch: main
+- Worktree: D:\Datas\OthersProjects\makelore
+- Base commit: 9fed0cc7c45df6b4ef01a52abc5045de478faa9c
+- Owner: codex
+- Status: Ready for Integration
+
+## Scope
+
+- Integrate completed MakeLore Token Point V2 account-usage source commits
+  `8e5abd8` and `6348e40` from task
+  `20260906-trace-makelore-usage-3d7a5c1e` onto local `main@9fed0cc`.
+- Reconcile the source task's accepted promotion candidate into canonical
+  `current-state.md` without changing its source task record.
+- Preserve the already integrated Agent Browser repair and three explicitly adopted
+  untracked task records in the primary worktree.
+
+## Intent And Constraints
+
+- Preserve ADR-004: Renderer uses fixed Host API routes while Electron Main owns
+  Works Square credentials and response projection.
+- Preserve Works Square as the sole Token Point balance authority; do not restore
+  the retired five-hour or rolling-seven-day contract and do not derive ledger state
+  in Renderer.
+- Preserve the non-manager privacy boundary using `can_manage_membership`, not
+  `family_shared`, because youth self entitlements are also non-managing.
+- Apply the two source commits as patches on the latest main rather than advancing to
+  the old source branch head, which would reverse the newer Agent Browser integration.
+- Do not modify or stage the three adopted untracked task records, deploy services,
+  run migrations, package the client, publish, or push remotely.
+
+## Outcome
+
+- Re-anchored the integration at `main@9fed0cc` after the blocking Main-worktree
+  owner was explicitly released, then applied source commits `8e5abd8` and
+  `6348e40` with `--no-commit` and no conflicts.
+- Verified the staged source task record is byte-for-byte identical to source head
+  `6348e40` and registered it as an unchanged adopted foreign document.
+- Integrated the V2 points route, strict Main projection, account-menu presentation,
+  privacy handling, and focused tests without changing any Agent Browser file.
+- Promoted the durable V2 account-usage contract and remaining live-release gaps to
+  canonical `current-state.md`.
+- The three pre-existing untracked task records remain unstaged and unchanged.
+
+## Verification
+
+- Source verification is recorded in task
+  `20260906-trace-makelore-usage-3d7a5c1e`: 72 focused tests, typecheck, scoped lint,
+  all Vite targets, diff/source checks, and two matching server contract tests passed.
+- Passed the same four focused Vitest files on `main@9fed0cc` plus the staged V2
+  integration (72 tests).
+- Passed `pnpm run typecheck` and scoped ESLint over all changed TypeScript/TSX files.
+- Passed `pnpm run build:vite` for Renderer, Electron Main, preload, and utility
+  bundles. Only the repository's existing Browserslist, dynamic-import, and chunk-size
+  advisories were reported.
+- Verified the staged source task record matches source head `6348e40` and the staged
+  path set contains no Agent Browser or README file.
+- Passed task-aware project-document drift checks with the source task record and the
+  three pre-existing untracked task records unchanged.
+
+## Follow-ups
+
+- Verify that the deployed Works Square API and database are on the V2 release and
+  migration head before releasing the paired client.
+- Run a signed-in packaged-client smoke against the deployed V2 service.
+
+## Promotion Candidates
+
+- None. This Integration Gate applies the accepted source promotion directly to
+  `.project-docs/30-worklog/current-state.md`.
