02 — Artifact Verification and Hash Audit

Date: 2026-06-03. Objective A. Independent verification that the canonical release package is internally consistent, hash-stable, and contains no FS-only or stale unclassified artifacts.

2.1 SHA-256 manifest audit — PASS (25/25 OK, 0 failures)

shasum -a 256 -c manifest-sha256.txt over …/one-roof-production-release-engineering-ultra-macro-2026-06-03/ returned OK for all 25 entries (11 docs + 13 SQL + the manifest's covered files), 0 mismatched, 0 missing. No tampering, no drift since publication.

2.2 Inventory completeness

• Docs: 11 (00–10), all hash-verified.
• SQL: 13 (8 executor tiers + orchestrator + 2 rollback + 2 verify + 1 revalidation), all hash-verified.
• FS-only artifacts: none. Stale/unclassified scripts in the canonical package: none. (The scratch dir /Users/nmhuyen/one-roof-clone-finalization-2026-06-03/sql/ holds the earlier finalization-era A–H + G_prod_* clone-build lineage, superseded by and consolidated into the canonical prod/ tiers; not part of the canonical package.)

2.3 Executor / rollback canonicality (read-level audit)

File	Hard gate	Mutation	Reversal
00_preflight	db=directus, ospa≥1, prereq views, axis absent, gap=210/own=0/conflict=0/emit=0	none (read-only)	n/a
10_structure	db=directus	11 tbl+31 view+1 fn, reads 0	DROP
20_responsibility_axis	db=directus, ospa≥1	+1 axis,+6 val,+1 rule; gap stays 210	DROP/DELETE
30_ownership_seed	db=directus, ospa≥1, gap=210/own=0/conflict=0	+30 ownership; gap 210→0	DELETE by tag
40_containment	db=directus, ospa≥1	+1 axis,+5 val,+1 rule,+35 assign,+35 own	DROP/DELETE
50_topic_finalization	db=directus, ospa≥1	topic axis +8 val,+7 map,+6 assign, auto decisions	DROP/DELETE
60_scanner_baseline	db=directus, ospa≥1	1 scan; asserts critical=0/emittable=0/outbox=0	truncate
90_verify	—	none (read-only)	n/a
99_run_all	inherits 00 + each tier	orchestration	per-tier
99_rollback_full	db=directus	DROP all + DELETE seed → greenfield	idempotent

Findings: every mutating tier is hard-gated on ospa≥1 AND db=directus; no executor path mutates production without the gate. Tier 1 is gated on db=directus only (ratification-independent — relevant to Option 3). Orchestrator stops on first error and verifies after each mutating tier. Rollback returns to exact greenfield and self-verifies. The copied executor/rollback files in this package's final_*_copy/ folders are byte-identical to canonical (diff-verified: 99_run_all, 00_preflight, 30_ownership_seed, 99_rollback_full).

2.4 Package fix applied

None required — passed every check unmodified. Only hygiene action (outside the package): re-created the golden-clone snapshot /tmp/clone_finalized_2026-06-03.dump.

Verdict: Objective A PASS.
