Closure-analysis lock. This packet classifies how each open criterion could be closed — by read-only evidence, by an Owner decision, by out-of-band recovery, or only behind a write gate. It closes nothing, resolves no blocker, and authorizes no act. "Closeable by read-only evidence" describes a future read-only step that is itself Owner-gated; nothing is verified here.
0. Status and non-authorization
STATUS: PASS — engineering / design-only. This is a complete closure analysis: for each Go/No-Go criterion (G-1…G-11) and each carried blocker, it states whether closure is possible by read-only evidence, requires an Owner decision, requires out-of-band source recovery, or remains a write-gated future act — and what exact evidence/decision each needs.
Engineering PASS ≠ authority PASS. A PASS means the closure map is complete on paper. It does not close any criterion or blocker. Default disposition: HOLD.
Pipeline position (downstream-only). Deliverable 2 of the Mega Gate Bundle; it sharpens Deliverable B's aggregate No-Go (carried) into a closure-route map. It opens no package and verifies nothing.
Non-authorization (explicit). As Deliverable 1 §0 (no DB write/DDL/DML; no runtime mutation; no inspect/certified writes; no gate flip; no owner assignment; no contract promotion; no pg_cron/queue enable; no source/prior-report patch; no current/staging corpus; no TD; no implementation; no blocker resolved; no channel selected; v0.1/FIX7 V3 not overwritten; v0.2 not authority). No blocker is marked resolved here.
Evidence basis — INHERITED_EVIDENCE. No runtime queried. Facts inherited from accepted read-only reports. AgentData metadata authoritative at read time. CAV-3/CAV-4/CAV-5 carried.
Reading discipline (Codex caveat, honored). All sources read directly from AgentData KB, bounded/sequential, by the main process — no parallel/background reader-agents, no sub-agents, no local-prose inference. /tmp = decode-scratch only, never SSOT.
1. Purpose
Answer the macro's first two questions precisely: (1) what exact evidence remains before actual B2 TD can be opened, and (2) which No-Go items can be closed by read-only evidence vs. which remain Owner decisions. The packet answers:
- Per criterion: what closes it? — §5 closure matrix.
- Which closures are write-free (read-only evidence)? — §5 column.
- Which require an Owner decision or out-of-band recovery? — §5 column.
- Which remain write-gated regardless? — §5 + §6.
- What is the closure-route summary? — §5 summary.
The one rule, above all detail. Closure is routed, not performed. A "read-only-closeable" criterion still needs an Owner-gated read-only pass to actually close it; a "decision" criterion is the Owner's act; nothing here resolves anything.
2. Sources read
All 25 required sources read first-hand from AgentData KB, by the main process, sequentially; none SOURCE_NOT_READ (full list in Deliverable 20 §2). Used principally: Deliverable B (the G-1…G-11 Go/No-Go criteria + PO-1…9); R2 readiness scope + R2a (the runtime facts a read-only pass would re-confirm); Phase-1B (the blocker bundle); the interface packet (S3/S4/S7/S8); operating-rules (fail-closed; read-only inventory rule).
3. Accepted baseline (carried, not re-derived)
The Go/No-Go criteria (Deliverable B §14), carried verbatim in substance:
| # | Criterion | Status today |
|---|---|---|
| G-1 | B2 13-field contract frozen and accepted | Go |
| G-2 | B3 inspect_* stud stable (runtime-reconfirmed) + B4 consumer re-verified |
Partial |
| G-3 | Điều 0-G rule-set recovered to an authoritative source (or Owner-accepted with caveat) | No-Go |
| G-4 | A channel selected from candidates + liveness/observability proven | No-Go |
| G-5 | Birth-producer governance owner (S2) assigned | No-Go |
| G-6 | Disposable staging/kho-tạm surface exists | No-Go |
| G-7 | S7 evidence contract honored + writers scoped (records-not-decides) | Partial |
| G-8 | Per-run S8 rollback unit + Điều 39 snapshot + downstream-certify handling defined; HOLD-2 acknowledged | Partial |
| G-9 | §8/BAD bad-input matrix committed to become runtime tests | Partial |
| G-10 | B7 holds warn-mode; transient GUC confirmed out-of-band | Partial |
| G-11 | CONS-002/003 + CELL-003/004/007 + Đ0-G recovery confirmed as prerequisites to downstream canonical materialization | No-Go |
Aggregate: NO-GO (1 Go, 5 No-Go, 5 Partial). Carried unchanged.
4. Analysis — closure routes
Each open criterion closes by exactly one of four route-types. Distinguishing them is the point of this packet:
- R/O — Read-only evidence (write-free). A future Owner-gated read-only pass (catalog reads, DB-captured snapshots) can move a Partial to Go by converting INHERITED_EVIDENCE into current evidence. Bounded by the tool-boundary caveats (no
crontab -l/systemctl/docker exec;/opt/incomex/dot/bin+ env unreadable; logs tail-only; transient GUC unreadable — CAV-3/CAV-4/CAV-5). - DEC — Owner decision. Only the Owner can take the act (select a channel; assign an owner; accept a working source with caveat).
- OOB — Out-of-band recovery. Owner-controlled, external to the inspected substrate (Điều 0-G source recovery, external S6).
- WG — Write-gated build. Closure requires building/writing something (staging surface; S7 writers; a runtime fail-closed test) — forbidden now, Owner-gated later.
A criterion may need more than one route (e.g. the channel needs DEC to select and R/O to prove liveness). The matrix records the gating route(s).
5. No-Go / Partial closure matrix
"Read-only-closeable?" = can a future Owner-gated read-only pass close it without any write. "Exact evidence / decision needed" is what that step would have to produce. Nothing is closed here.
| Criterion / blocker | Today | Closure route(s) | Read-only-closeable? | Exact evidence / decision needed | Remains an Owner decision / write-gated? |
|---|---|---|---|---|---|
| G-1 contract frozen | Go | (already Go) | n/a | — | No |
| G-2 B3 stud + B4 consumer | Partial | R/O | Yes | A read-only re-confirm of the three inspect_* column types/order (information_schema) + that fn_birth_auto_certify fires only when all three present and only reads them (catalog/pg_proc). |
No — closes by read-only evidence |
| G-3 Điều 0-G authoritative | No-Go | OOB (+ optional DEC) | No | Either (a) the Đ0-G PEN/STAMP/GATE rule-set recovered to an authoritative source via external S6, or (b) an explicit Owner decision to accept the architecture/ working source as the TD basis with the caveat recorded. |
Yes — out-of-band recovery and/or Owner acceptance |
| G-4 channel selected + live | No-Go | DEC + R/O | Partly | DEC: Owner selects a candidate (host cron / agent-api executor). R/O: prove liveness for the chosen channel (host-cron entry present in wf_host_crontab_snapshot; or agent-api contract bound + master-switch state read). The selection is not read-only-closeable; the liveness proof is. |
Yes — selection is an Owner decision (Deliverable 4/5/6) |
| G-5 S2 owner assigned | No-Go | DEC (→ WG to write) | No | Owner assigns the birth-producer governance owner via Điều 37 → Điều 32; governance_object_ownership=0 today. The decision is the Owner's; writing it is a separate write gate. |
Yes — Owner decision then write-gated |
| G-6 staging surface exists | No-Go | WG | No | A built, isolated, disposable staging surface (Deliverable 11/12/13 define readiness; the build is future TD). | Yes — write-gated build (no schema/corpus now) |
| G-7 S7 contract + writers | Partial | R/O (contract) + WG (writers) | Partly | R/O: confirm the S7 contract shape + that kg_quality_log/audit-queue are append-only/records-not-decides. WG: the S7 writers are a future build. |
Yes — writers write-gated (Deliverable 16) |
| G-8 S8 unit + downstream-certify | Partial | R/O (carried facts) + DEC/WG (mechanism) | Partly | R/O: re-confirm fn_iu_enact atomic/fail-closed/post-verify pattern + that all-three-inspect_* triggers B4. The rollback mechanism and the downstream-certify unwind are FUTURE_TECHNICAL_DESIGN + HOLD-2 (open). |
Yes — mechanism write-gated (Deliverable 17) |
| G-9 bad-input → runtime tests | Partial | WG (needs built producer + staging) | No | The producer must exist to run BAD-1…BAD-15; the plan (Deliverable D / Deliverable 14) is committed but not runnable. | Yes — needs a built producer (write-gated) |
| G-10 B7 warn-mode + GUC | Partial | R/O (persisted) + OOB (transient) | Partly | R/O: persisted GUC layer is empty (pg_settings app.%=0, pg_db_role_setting=0) — confirmable read-only. OOB: the transient session value is unreadable (CAV-5) — needs an out-of-band Owner check. B7 stays warn-mode regardless (it is a separate block, not opened). |
Yes — transient GUC is out-of-band |
| G-11 CONS/CELL + Đ0-G prereqs | No-Go | DEC/WG (CONS/CELL) + OOB (Đ0-G) | No | CONS-002/003 + CELL-003/004/007 are open structural blockers (resolution is a separate Owner-gated workstream); Đ0-G recovery is OOB. B2 itself never canonicalizes, so this gates downstream materialization, not B2's inspect_* writes. |
Yes — separate Owner-gated workstreams |
Carried blockers (not B2 Go/No-Go criteria, but gating context — all OPEN):
| Blocker | Closure route | Read-only-closeable? | Note |
|---|---|---|---|
| HOLD-2 (no atomic birth-certify promote txn) | WG | No | No channel/decision closes it; surfaced in G-8 (Deliverable 17). |
HOLD-1 (iu_staging_* pilot) |
WG | No | Separate R5 workstream; not in B2's path. |
| RISK-BYPASS (residue + warn-mode + latent kill-switch) | DEC/WG | Partly (residue is read-only-scopeable) | Separate R4 workstream; disposition never auto-revert. |
| Điều 39 runtime-EMPTY (2199 edges / 0 provenance) | WG | No | R1-K lane; cross-checked in Deliverable 18; B2 must not touch it. |
| Điều 35 production-readiness FAIL | WG | No | R3 workstream; carried with any DOT-governance reuse. |
| CONS-002/003, CELL-003/004/007, GOV-016/017, GOV-REUSE-001 | DEC/WG | No | Structural; gate materialization (G-11). |
Closure-route summary.
- Closeable by read-only evidence (write-free, but still Owner-gated to run): G-2 fully; G-7/G-8/G-10 partly (the contract/persisted/carried-fact halves). This is exactly the scope of the recommended Option E read-only re-verification (Deliverable 1).
- Owner decisions: G-4 (channel selection), G-5 (owner assignment), G-3 (accept working source, if not recovered).
- Out-of-band recovery: G-3 (Điều 0-G), G-10 (transient GUC).
- Write-gated builds: G-6 (staging), G-7 (S7 writers), G-8 (rollback mechanism), G-9 (runtime tests, needs producer), G-11 (CONS/CELL materialization prerequisites).
No criterion is closeable purely by this packet; none is closed. Even the read-only-closeable ones require a separately Owner-authorized read-only pass to actually close (the same class of act as Phase-1).
6. Owner-gated future work
| Future work | Gate required | Forbidden now? |
|---|---|---|
| Run the read-only re-verification pass that would close G-2 (and parts of G-7/G-8/G-10) | Owner authorization to open a read-only pass | Yes |
| Select the channel (closes G-4 selection half) | Owner decision (Deliverable 4/5/6) | Yes |
| Assign the S2 producer owner (closes G-5) | Điều 37 → Điều 32 | Yes |
| Recover the Điều 0-G source (closes G-3) | external S6 — Owner out-of-band | Yes |
| Confirm the transient GUC out-of-band (closes G-10 transient half) | Owner out-of-band — read-only, not a runtime write | Yes |
| Build staging (closes G-6) / S7 writers (G-7) / rollback mechanism (G-8) | Điều 32 — write-gated | Yes |
| Resolve CONS/CELL (closes G-11 prerequisites) | separate Owner-gated workstream | Yes |
7. What remains unresolved
- Nothing is closed; aggregate B2 TD remains NO-GO. This packet routes closures; it performs none.
- The read-only-closeable set still needs an Owner-gated read-only pass to actually close — closure is not automatic and not done here.
- G-3 / G-10 transient depend on out-of-band acts (Điều 0-G recovery; transient GUC) this lane cannot perform (CAV-5; external S6).
- Blockers — all OPEN, none resolved: CONS-002, CONS-003, CELL-003/004/007, HOLD-1, HOLD-2, RISK-BYPASS, GOV-016/017, GOV-REUSE-001, Điều 39 runtime-EMPTY, Điều 35 production-readiness FAIL.
- FUTURE_TECHNICAL_DESIGN_REQUIRED (NOT written here): the read-only pass's queries, the staging build, the S7 writers, the rollback mechanism, the runtime tests.
8. Ready for GPT/Codex review
Yes — as a design-only closure-route map, not a closure.
Core rule, kept above all detail: the path to actual B2 TD has a small read-only-closeable set (G-2 + parts of G-7/G-8/G-10), a small Owner-decision set (G-4/G-5/G-3), an out-of-band set (G-3/G-10-transient), and a write-gated set (G-6/G-7/G-8/G-9/G-11). None is closed here; the read-only-closeable ones still need an Owner-gated read-only pass.
Default disposition: HOLD. Engineering PASS = a complete closure map; it is not an Owner authorization to close anything. No PASS authorizes writes. All blockers remain OPEN.
