Tail-end of the PDD v2 work (Assumptions field + safety/liveness split +
machine-executable Evidence). Three documents that still referenced v1's
4-field Purpose Gate are updated to the full 8-field PDD packet:
- docs/SPEC_FIRST_TDD.md — Purpose Gate now lists all 8 fields with the
Assumptions and Failure-boundary additions inline.
- skills/requesting-code-review — replaces "Purpose & Consumer" section with
"PDD packet (all 8 fields)" restated verbatim from .sf/active/{unit-id}/pdd.md.
Falsifier and Scope-defence sections clarified vs Failure-boundary and
Non-goals to remove overlap.
- skills/receiving-code-review — Purpose Gate criterion updated to demand
the full PDD packet with machine-executable Evidence, not just
Purpose/Consumer/Value-at-risk.
PDD packet (inline):
- Purpose: every artefact that references "Purpose Gate" agrees on the same
8-field definition; reviewers and reviewees read the same packet.
- Consumer: spec-first-tdd, requesting-code-review, receiving-code-review.
- Contract: all three documents list the same 8 fields with the same
Assumptions / safety+liveness / machine-executable-Evidence wording.
- Evidence: grep confirms PDD packet references in all three; typecheck:extensions exits 0.
- Non-goals: no edits to the PDD skill itself (already v2); no edits to other
skills referencing v1 Purpose Gate beyond these three (they don't exist).
- Invariants: existing review-loop sections preserved; only Purpose-Gate-
related sections rewritten.
- Assumptions: PDD v2 SKILL.md is the canonical source of field definitions;
these three documents are projections of it.
