Hard-floor lock. Reconfirms the B2 hard floor — the invariants no waiver can cross. It grants no waiver and authorizes nothing.
0. Status and non-authorization
STATUS: PASS — engineering / control. The B2 hard floor reconfirmed; it survives any waiver. No waiver granted.
Engineering PASS ≠ authority PASS. Default disposition: HOLD. No waiver; no TD; no DB write/DDL/DML; no blocker resolved; v0.1 not overwritten; v0.2 not authority.
Evidence basis — INHERITED_KB_EVIDENCE (waiver map hard floor; B2-AC-1…14) + FRESH (RQ-1/10). Reading discipline: main process, no reader-agents.
1. Purpose
Reaffirm what is non-negotiable for B2 regardless of which gates the Owner later waives — so no waiver (e.g. GATE-3) is read as relaxing fail-closure or block isolation.
2. Sources / evidence read
The owner waiver map (hard floor); the inspect-producer TD-prep (B2-AC-1…14); the interface anti-coupling; the fresh RQ-ledger. Read directly, main process.
3. Accepted baseline (carried)
A waiver trades readiness completeness for schedule, never fail-closure or block isolation. The hard floor survives any waiver.
4. B2 hard floor (non-waivable — reconfirmed)
| # | Hard-floor invariant | Grounding | Fresh check |
|---|---|---|---|
| HF-1 | B2 must not certify / canonicalize / mint identity / write KG (B2-AC-1…4) | C6; interface | RQ-1 (B2 writes only inspect_*; canonical cols present-unused) |
| HF-2 | No faked inspect_*=now() / no fused INSERT (B2-AC-5/6) |
R2a §7; C6 §12 | — |
| HF-3 | The channel must not leak into the contract (B2-AC-7) | C6; Codex | — |
| HF-4 | A per-run rollback unit must exist (B2-AC-9; S8) | interface S8; HOLD-2 OPEN | — |
| HF-5 | A governed S2 owner must exist (GATE-5 non-waivable) | waiver map | RQ-15 (governance_object_ownership=0) |
| HF-6 | A staging workshop must exist (GATE-6) | waiver map | unbuilt |
| HF-7 | No engineering PASS treated as Owner authorization (B2-AC-10) | chain | every §0 |
| HF-8 | v0.2-hardening not FIX7 authority (B2-AC-11) | tool lock | — |
| HF-9 | Fail-closed default: bad input ⇒ no stamp + audit (BI-1…12; "không chắc đúng = sai") | C6 §8; OR §0.1 | producer MISSING (RQ-10/11) |
Reading. The hard floor is intact and survives any waiver the Owner might grant (including a GATE-3 Đ0-G waiver). Fresh evidence reconfirms the load-bearing facts (B2 writes no canonical; no producer; no owner). No waiver granted here.
5. Result
The B2 hard floor stands; GATE-4 (channel) + GATE-5 (owner) remain non-waivable; a GATE-3 waiver, if the Owner grants it, does not touch the hard floor. No waiver granted.
6. Owner-gated future work
Granting any waivable gate (with caveat) is the Owner's act; the hard floor is never waivable.
7. What remains unresolved
- Hard floor intact; no waiver granted; HOLD-2 (HF-4) OPEN.
- Blockers — all OPEN.
8. Ready for GPT/Codex review
Yes — as the B2 hard-floor reconfirmation.
Core rule: the hard floor (HF-1…HF-9) is non-waivable and survives any waiver; GATE-4/5 non-waivable; no waiver granted.
Default disposition: HOLD. Engineering PASS ≠ authority PASS. All blockers remain OPEN.
