Process Retrospective (Deferred Skeleton)

Formalized skeleton for the process-retrospective frame port. The port is declared and its credit row emitted as DEFERRED(#348): ... on every PR until issue #348 ships the live producer and trigger predicate.

Deferral Status

Field	Value
trigger-status	deferred
trigger-deferred-to	#348 ("Thin Harness E — Close the learning loop")
trigger-deferred-since	2026-05-03
applies-when	never (deterministic false — deferred port)

What this means: on every PR, the frame predicate evaluator resolves never to false, the port is excluded from the umbrella's 95% coverage denominator, and Code-Conductor emits a DEFERRED(#348): credit row via Build-DeferredPortCreditRow.

When #348 Ships

Issue #348 ("Thin Harness E — Close the learning loop") will:

1. Replace applies-when: never with the real trigger predicate
2. Flip trigger-status: deferred → trigger-status: live
3. Remove trigger-deferred-to and trigger-deferred-since fields
4. Implement the retrospective content methodology in this SKILL.md body
5. Add the explicit-skip adapter per the port's skip contract

Until then, this skeleton must not be invoked — the applies-when: never frontmatter guarantees the port never triggers.

#443 ↔ #348 Split Contract

Artifacts that are stable (must be preserved when #348 ships):

• frame/ports/process-retrospective.yaml port YAML (fields change, file persists)
• skills/process-retrospective/SKILL.md (this file; body replaces, frontmatter evolves)
• skills/process-retrospective/adapters/process-retrospective-explicit-skip-adapter.md (name persists)
• DEFERRED(#348): prefix as migration-detection contract (regex ^DEFERRED\(#\d+\):)

Artifacts that are scaffolding (will be replaced by #348):

• The applies-when: never frontmatter line
• The trigger-status: deferred + trigger-deferred-to + trigger-deferred-since metadata
• The deferred skeleton body text in this file

Gotchas

• Never invoke this skeleton directly. The applies-when: never frontmatter guarantees the port never fires. Any code that bypasses the predicate evaluator and calls this skill directly will get an empty skeleton, not a real retrospective.
• Do not copy this skeleton's frontmatter into a live skill. When #348 ships, the applies-when, trigger-status, trigger-deferred-to, and trigger-deferred-since fields must all change. Copying them verbatim would silently defer the live port.
