P0008 (accept + execute): validator-deliverable convention in release-validation-gate

[klappy]

What this PR does

Combined acceptance + execution of promotion P0008 — codifies the validator's deliverable shape for the release-validation-gate workflow.

Acceptance (1 file)

• docs/promotions/P0008-pr-validator-dolcheo-ledger-as-deliverable.md
  • promotion_status: proposed → accepted
  • Tags array "proposed" → "accepted"
  • Status section header → accepted (2026-05-05)
  • Review Notes filled

Execution (1 file, +42 lines)

• canon/constraints/release-validation-gate.md — new section before ## Related Canon:
  • ## Validator Deliverable Convention — The PR-NN Fresh-Validator Ledger
  • Two-artifact requirement: DOLCHEO ledger at canon/encodings/pr-NN-fresh-validator-ledger.md + companion handoff at canon/handoffs/pr-NN-fresh-validator-review.md
  • DOLCHEO section ordering specified (D, O, L, C, H, O-open) with what each captures
  • Constraints (C) MUST be paired with permanent or v+1 revisit candidate — silent acceptance is the named failure mode
  • Receipts cite PTXprint PR Add Anti-Cache Lying constraint and content-addressed storage implementation #30 v1.3 telemetry as the worked example

Why this is third in the queue

The release-validation-gate runs on every load-bearing PR — including the 7 still-queued promotion PRs in this sweep. Codifying the validator deliverable shape now means those subsequent PRs (or the next fresh-validator dispatch) have canon to point at, rather than re-deriving the format under time pressure.

Position in the 8-proposal sweep

#	ID	Status
1	P0009	PR #167
2	P0001	PR #168
3	P0008	this PR
4	P0007	next — DoD as 5–7 agent-observable behaviors
5-8	P0006, P0003, P0004, P0005	queued

DoD

• Proposal frontmatter promotion_status flipped to accepted
• Review Notes block filled
• Canon edit text matches P0008 §"Proposed Language" verbatim
• Insertion point matches P0008 §"Section" (append, before Related Canon)
• No other canon docs touched

Note

Medium Risk
Medium risk because it adds a new, enforced-by-convention deliverable requirement for fresh-validator reviews, which may change release-validation-gate workflows and reviewer expectations. Changes are documentation/canon-only with no runtime code impact.

Overview
Accepts and executes promotion P0008 to standardize fresh-validator outputs under release-validation-gate.

Updates canon/constraints/release-validation-gate.md with a new Validator Deliverable Convention that requires two repo-committed artifacts for each fresh-context validator review: a DOLCHEO-structured ledger at canon/encodings/pr-NN-fresh-validator-ledger.md (with mandated D/O/L/C/H/O-open sections, including explicit permanent vs v+1 revisit candidate constraint labeling) and a companion prose review at canon/handoffs/pr-NN-fresh-validator-review.md.

Promotes docs/promotions/P0008-pr-validator-dolcheo-ledger-as-deliverable.md from proposed to accepted, updating metadata and filling the review notes with the acceptance decision/date.
