Implement

POCDD — Implement (the implementation stage)

Move the proven Implementation into the product. Read ../shared/conventions.md and the target POC first; resolve it with pocdd_resolve <name>.

Precondition

The POC should be phase: ready-to-implement (Remaining gaps empty). If it is not, stop and report: list the open gaps and route to /poc work <name> or a decision batch instead of porting on top of unresolved gaps.

Porting order

Drive from the Implementation section's directives — each carries an acceptance check; satisfy it.

1. Lift datatypes and pure functions first (the domain model, filter helpers, the core computation) into the appropriate production package.
2. Wrap with framework boundaries — views/endpoints, permissions, feature flags, settings.
3. Mirror proven behavior — each production capability maps to a Finding or a documented intentional difference. Preserve dedupe keys / external ids exactly as the POC justified them.
4. UI last — it consumes the stabilized contract.

Verification & commits

• For each ported slice, run its acceptance check (the command/test/diff named in the directive). For runnable POCs, diff production output against the POC's.
• Commit per slice using the host repo's conventions (read its AGENTS.md); this skill does not impose its own commit rules on the product repo.
• After porting, if the POC was runnable, note that it can be kept as a parity oracle (/poc archive <name>) or removed (/poc remove <name>).
