# 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.
