Read-Only Staging No-Touch Readiness Recheck

Date: 2026-06-18 · Workstream: LEGO-PILOT-SLICE-0-R2-B2-READONLY-EVIDENCE-OWNER-PATH-MACRO-2026-06-18 (Deliverable 19 of 30) · Editorial revision: rev1 Class: read-only staging readiness recheck · READ-ONLY · NON-ENACTING · NON-AUTHORIZING · NO staging schema · NO corpus · NO extraction · NO write performed.

Metadata convention. Editorial revision (rev1) only. AgentData storage revision/content_length authoritative at read time; not pinned here.

Staging-readiness lock. This packet re-confirms the staging no-production-touch readiness can be specified further read-only without building staging. It writes no schema/table/SQL/corpus and no extraction plan. STAGING_SCHEMA_OR_CORPUS_DRIFT guarded.

0. Status and non-authorization

STATUS: PASS — engineering / read-only. The no-touch proof (NT-1…NT-8) is re-confirmed as a requirement, with a fresh "before" production baseline captured read-only (Deliverable 8). Engineering PASS ≠ authority PASS. Default disposition: HOLD. No staging schema/corpus/extraction; no snapshot beyond read-only counts; no DB write/DDL/DML; no TD; no blocker resolved.

Evidence basis — FRESH_READONLY_EVIDENCE (the production "before" counts) + INHERITED_KB_EVIDENCE (the NT-1…NT-8 proof shape; staging IO contract). Reading discipline: main process, no reader-agents.

1. Purpose

Answer macro question 6 (can staging/no-touch proof be specified further read-only without building staging?). §4 records the fresh "before" baseline and re-affirms NT-1…NT-8 as requirements. §5 classifies (read-only verified that the proof is specifiable; the surface stays unbuilt).

The one rule: staging is a disposable workshop / IO contract; the no-touch claim must be proven by before/after production counts, not asserted. This packet captures the read-only "before" baseline only; it builds nothing.

2. Sources / evidence read

Deliverable 1 (production counts) + Deliverable 8 (cert-state snapshot); Mega Gate Staging No-Production-Touch Proof Matrix (NT-1…NT-8); Staging IO Contract (Deliverable C). Read directly, main process.

3. Accepted baseline (carried)

No-touch proof (NT-1…NT-8): production inspect_*/certified/canonical/identity/KG unchanged before/after; containment after delete-fast; no silent PASS. Staging is IO-contract-only; the surface is unbuilt (GATE-6 No-Go).

---

4. Read-only evidence observed (FRESH, 2026-06-18)

Fresh "before" production baseline (read-only counts; the reference any future no-touch proof would compare its "after" against):

• production certified=true = 1,402 (all 2026-03-21 buckets);
• production certified=false = 1,211,635;
• uncertified rows with any inspect_* = 0;
• universal_edges = 2,199 / 0 provenance (KG untouched reference);
• this read-only pass changed none of the above (it is SELECT-only; query_pg cannot write).

NT-1…NT-8 re-affirmed as requirements (the proof is fully specifiable read-only; the proof execution needs a built pilot to bracket): NT-1 production inspect_* count unchanged; NT-2 certified unchanged; NT-3 canonical fields unchanged; NT-4 zero identity mint; NT-5 zero KG write; NT-6 zero certify trigger from staging; NT-7 containment after delete-fast; NT-8 no silent PASS.

---

5. Classification / result

• The no-touch proof is fully specifiable read-only (NT-1…NT-8 + the fresh "before" baseline) — this is the read-only contribution.
• The staging surface stays unbuilt (GATE-6 = NO_GO_WRITE_GATED); the proof execution needs a built pilot.
• No schema/corpus/extraction written; STAGING_SCHEMA_OR_CORPUS_DRIFT not triggered.

---

6. Owner-gated future work

Future work	Gate required	Forbidden now?
Build the staging surface	Điều 32 (staging build is future TD)	Yes
Take the before/after no-touch snapshots against a built pilot	Owner authorizes a read-only pass + a built pilot	Yes

---

7. What remains unresolved

• Staging surface not built (GATE-6 No-Go).
• No-touch proof is a requirement + a captured "before" baseline, not a result.
• Blockers — all OPEN.

---

8. Ready for GPT/Codex review

Yes — as a read-only staging no-touch readiness recheck.

Core rule: NT-1…NT-8 are fully specifiable read-only and a fresh production "before" baseline is captured (1,402 cert / 1,211,635 uncert / KG 2199-0prov); the staging surface stays unbuilt; no schema/corpus/extraction written.

Default disposition: HOLD. Engineering PASS ≠ authority PASS. All blockers remain OPEN.
