Plan a section

Record contract

Read: project://manifest, project://config, project://state, project://decisions, project://structure/outline, project://validations/*, project://sections/{section}, project://sections/{section}/context, project://sections/{section}/research, project://sections/{section}/summary, project://sources/{source}, project://evidence/{evidence}. Produce: project://sections/{section}/plans/{plan} (create), project://validations/{validation} (create), project://checkpoints/{checkpoint} (create), project://sections/{section} (update), project://state (update).

Resolve every logical URI through the host adapter. Portable v1 JSON records are the source of truth: schema-validate before a write, preserve stable IDs, update revision and timestamps where required, and replace records atomically. Never pass a literal logical URI to a shell command or infer record state from a legacy Markdown control file.

Manuscript prose and supporting context, research, plan, review, summary, handoff, and deliverable artifacts retain their authored format (normally Markdown). Link them from the relevant v1 record; do not convert manuscript prose into project-state JSON.

Procedure

1. Resolve one section record, load its linked context, research, evidence, decisions, and outline constraints, and enumerate the bounded project://validations/* collection before any specialist dispatch.
2. Filter those records to candidates whose subject_uri is exactly project://structure/outline and whose action_id is exactly create-outline. A candidate is current only when executed_at >= outline.updated_at. Because the v1 validation schema carries no outline revision or content hash, disclose that this timestamp test is a conservative freshness proxy.
3. Require exactly one current candidate and require its status to be passed. Separately verify that the current outline and target section are consistent with all current locked and deferred author choices: honor locked choices and do not treat deferred choices as resolved. A missing, stale, ambiguous, or non-passing candidate, or a decision contradiction, blocks all specialist dispatch and every plan, section, state, or validation write. Only a recovery checkpoint may be proposed on this blocked path, and it may be written only after a complete record preview and explicit author approval.
4. Only after those prerequisites pass, delegate a bounded plan to section-planner, then require a fresh plan-checker pass over claim coverage, dependencies, file scope, citations, and decision fidelity.
5. At confirm_plan, preview the plan and validation; on approval link the plan, update section status to planned, and reconcile state. Create a checkpoint for unresolved judgment instead of bypassing the required checker.
