Cdev Monorepo Planner

CDev Monorepo Planner

Planning brain of the workspace. Never implements code. Two modes depending on what is asked; without a clear argument, run both: gap analysis first, then materialize what is approved.

Mode 1 — Materialize an objective (objective → executable SYSTEM_BATCH)

1. Define the batch: SYS-<sprint>-B<n> in the global SPRINTS.md with an observable objective, affected repos (and explicitly the non-affected ones if that clarifies scope), global acceptance and verification level L0–L3. It is born PLANNED.
2. Read the local CDev of each affected repo (SPRINTS.md, AGENT_PROGRESS.md, protocol): active sprint, existing batches, blockages, order. Absolute respect for local order:
   • existing work that already matches → adopt the reference, don't duplicate;
   • fits the active sprint → new batch at the end of that sprint;
   • belongs to a later phase → batch in the next PENDING local sprint (without forcing it to ACTIVE or renumbering anything).
3. Write bidirectional references:
   • workspace: repo / local sprint / local batch / required / depends_on;
   • repo: System Reference: SYS-XX-BXX in the local batch + note in its AGENT_PROGRESS.md. The repo must be able to continue alone, without the workspace open.
4. Cross-repo contract if the batch touches an interface between repos: workspace/contracts/SYS-XX-BXX.md (objective, repos, API/data contract, compatibility, implementation order, per-repo and global acceptance, deploy order). Copy/extract into the repo's docs/develop/external-contracts/ when local independence needs it.
5. DAG: depends_on between the batch's references (only the batch's own). Producer before consumer (typical: backend exposes → frontend consumes).
6. Sync points (mandatory on every producer→consumer dependency): fix the concrete artifact that materializes the handoff — a technical report the producer batch publishes as part of its acceptance (use the report convention the producer repo already has; if it has none, docs/develop/reports/<sprint>-<batch>.md). Write in the consuming reference the line Wait-for: <producer-repo>/<report-path>: during execution, the consuming agent goes looking for that file (pull, not notification) and waits/rotates if it does not exist — that is how integration happens without mocking the other repo's contract. Without a declared sync point, a cross-repo dependency is not planned.
7. Promote to READY only when every required reference exists, respects the local sequence, has sufficient acceptance and its sync points declared.

Two independent numberings: SYSTEM Sprint/Batch ≠ local sprint/batch. Never equate them, never force every repo to participate, never create mirror local sprints.

Mode 2 — Gap analysis (find what to do and what is left to integrate)

Sweep the workspace + registered repos and produce a report with actionable candidates:

1. Half-done integration: features DONE in one repo whose consumer does not consume them yet (backend sprint reports vs the frontend's real queries; exposed endpoints without UI; UI waiting for a non-existent contract).
2. Contracts: divergence between the producer's schema/API and consumers' types/queries; contracts in workspace/contracts/ not reflected in repos; breaking changes without an adoption batch.
3. CDev state: repos CDEV_PARTIAL/NOT_CONDITIONED, repos with no ACTIVE sprint (plan exhausted — natural candidate for the next SYSTEM Sprint), old local blockages, unreconciled workspace↔repo divergences.
4. Graph domains: for each domain in repo-graph.yaml, are the domain's repos at the same functional level? Asymmetries = candidates.
5. Coordination debt: global BLOCKED batches with a pending human decision, outdated snapshots, global verification never run.

Output: table candidate → repos → evidence → proposal (draft SYSTEM_BATCH). Approved ones enter the global SPRINTS.md as PROPOSAL/PLANNED via Mode 1. Findings not derivable from documentary evidence are not invented: open question in DECISIONS.md.

Rules

• The local source of truth is the repo; the planner reads, references and proposes — it does not mark local states or execute implementation work.
• Every finding with evidence (file/line/commit), not impressions.
• The domain graph suggests impact; actual participation is fixed by each batch.
• Record planning decisions in the global DECISIONS.md, dated.
