+# Task: Implement MakeLore Development Data Service P0 client
+
+## Identity
+
+- Task ID: 20260826-makelore-data-service-client-b72e4c19
+- Mode: Feature
+- Branch: codex/20260826-makelore-data-service-client-b72e4c19-makelore-data-service-client
+- Worktree: D:\Datas\OthersProjects\makelore-data-service-client-b72e4c19
+- Base commit: f2456039230f68e3ecb2c8653fc3379c23bbe5ce
+- Owner: codex-root
+- Status: Planning
+
+## Scope
+
+- Coordinate the repository-local `implement-spec` run for client tickets ML-00
+  through ML-09 from post-Pi-integration base
+  `f2456039230f68e3ecb2c8653fc3379c23bbe5ce`.
+- Deliver durable MakeLore project identity, Main-owned Data Service cloud/Host
+  operations, purpose-specific Pi tools, preview data sessions and CDP injection,
+  the thin generated SDK, bundled Data Service Skill, focused/full verification,
+  repository-local review, and one remediation pass when findings require it.
+- Own the client implementation branch and merge only commits returned by isolated
+  ticket worktrees in dependency order.
+
+## Intent And Constraints
+
+- Follow the server repository's implementation specification, ticket graph,
+  canonical integration contract, and accepted ADR without reopening the frozen P0
+  product scope.
+- Preserve the integrated Pi `0.84.2` hard cutover, product-neutral Snapshot/Patch
+  contracts, Main/Renderer trust boundary, current Host route ordering, and the
+  existing Agent Browser abstraction.
+- `.niancode/project.json` owns the durable optional `projectId`; local project IDs,
+  Pi session/resource IDs, and the `opencode-projects` compatibility store name remain
+  local identities.
+- Electron Main remains the only Works credential owner. Generated code receives only
+  an ephemeral exact-Origin data capability; no credential, owner, path, arbitrary
+  endpoint, or cloud project ID becomes a model-controlled input.
+- Do not restore OpenCode, add Firebase compatibility, published-runtime support,
+  retries for ambiguous writes, a filesystem-copy engine, or a generic operation
+  multiplexer.
+- The root `main` worktree remains clean and unowned. All writes stay in this isolated
+  coordinator worktree or ticket-specific linked worktrees.
+
+## Planning Gate
+
+- Result: Passed on 2026-08-26.
+- Loaded MakeLore `AGENTS.md`, required project-memory entry documents, current state,
+  accepted auth and Pi decisions, relevant architecture/domain/evidence/commitment
+  material, the cross-repository Data Service spec/graph/contract, and the exact Pi,
+  Host API, project-storage, session, and Agent Browser seams at the recorded base.
+- Registry review found 147 historical owners. Most are ready-for-integration and
+  represented in the selected base. Ten remain marked planning; nine have placeholder
+  scopes and therefore unknown coordination state, while one owns an unrelated AI
+  Design E2E file. No declared Data Service or owned-path semantic conflict exists.
+- Real PostgreSQL, signed-in accounts, deployment inputs, and platform-specific E2E
+  prerequisites remain external acceptance inputs and will not be inferred as passed.
+
+## Ticket Ownership
+
+- ML-00: coordinator in this worktree.
+- ML-01 through ML-07: isolated implementer worktrees from the exact merged frontier
+  commit, with the file ownership defined by the ticket graph.
+- ML-08: repository-local merger in this implementation worktree.
+- ML-09: read-only review followed by one isolated remediation implementer if needed.
+- X-01: coordinated only after reviewed server and client branches are ready.
+
+## Outcome
+
+- Not completed.
+
+## Verification
+
+- Not run.
+
+## Follow-ups
+
+- None recorded.
+
+## Promotion Candidates
+
+- None recorded.
