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: f245603923
Owner: codex-root
Status: Planning

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.

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.

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.

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.
