FIX7 P0 Birth-Blueprint — Dry-Run + Execution-Readiness Report (2026-06-11)

Host: T1 / Claude Code / MYTHOS · Lane: FIX7_P0_DRYRUN_STAGING_ROLLBACK_AND_EXECUTION_READINESS_MACRO_2026_06_11
Final status: FIX7_P0_DRYRUN_AND_EXECUTION_REVIEW_PACKET_READY
Owner decision consumed: AUTHORIZE_DRYRUN_ONLY
Authority of this doc: DRYRUN_NON_AUTHORITY. Staging-only. Authorizes nothing; mutates no production.
Codex consulted: NO · Owner asked mid-run: NO · Production mutation: NO · Implementation execution: NO · REAL_RUN / QT001 / permit / activation / repoint / cutover: NO.

Under owner AUTHORIZE_DRYRUN_ONLY, T1 ran the planning packet's dryrun-design.json (DR-0..DR-5) in an isolated local /tmp staging workspace, generated real evidence, proved rollback in staging, applied TKT Base L0–L3, ran 20 fail-closed probes, and produced this execution-readiness review. Packet root: knowledge/dev/reports/architecture/fix7-p0-dryrun-and-execution-readiness-packet-2026-06-11/ (packet_tree 60fc0b724a8e9092f0e080f39760df0d7b292bc03b6dd298bded6de84ad77432).

A. Authority + planning consumption table

artifact	expected	actual	verified?	role	limitation
N7 envelope	`efb0c574…53d32`	`efb0c574…53d32`	YES (byte-exact + read-back)	approval event	binds no N8/P7 (acyclic)
N8 detached seal	`daa70c39…7e1a1`	`daa70c39…7e1a1`	YES (byte-exact)	Codex detached seal	binds no P7
P7 authoritative pin	`9ddb27c3…34550`	`9ddb27c3…34550`	YES (byte-exact)	pins rev3 + Packet V3	`implementation_authorized_by_p7_alone=false`
Seal packet tree	`3890cd34…a234`	`3890cd34…a234`	YES (sha256(HASH_MANIFEST) recompute)	seal provenance	—
Planning packet tree	`f470d0d0…fe8f`	`f470d0d0…fe8f`	YES (14/14 byte-exact, RERUN PASS)	planning identity	paper-only
canonicalizer rev3	`49c386a9…b734d0` / 38756 B	`49c386a9…b734d0` / 38756 B	YES (DR-1 fresh fetch + recompute)	operative canon body	rev3 confirmed (doc revision 3)

Evidence: logs/A_verify_inputs.log, logs/DR1_seal_vs_bytes.log. Three seal node JSON files reconstructed byte-exact vs the seal HASH_MANIFEST.txt; seal tree recomputed == 3890cd34…a234. Planning packet 14/14 shasum -c OK, validator exit 0, 15/15 probes fail-closed, RERUN_RESULT: PASS.

B. Precondition recheck (12 items)

Re-evaluated under AUTHORIZE_DRYRUN_ONLY: 0 BLOCKS_DRYRUN, 8 PASS, 4 BLOCKS_EXECUTION_ONLY (PC-2 OPT-4, PC-7 REAL_RUN, PC-8 QT001/cutover, PC-12 production scope). PC-3 seal-vs-bytes and PC-6 rollback — UNKNOWN in planning — are now PASS (DR-1 + RB-2/3/4 executed). dryrun_can_proceed=true, execution_ready=false. Machine form: fix7-p0-dryrun-precondition-recheck-2026-06-11.json.

C. Staging isolation

Workspace /tmp/fix7p0-dryrun.<rand> (local laptop mktemp). is_production=false; no connection to production PG / Directus / system_issues / registry-row; disposable (rm -rf); evidence-capturable. No query_pg/pg_schema/directus_* tool invoked in the dry-run. Machine form + forbidden-surface table: fix7-p0-dryrun-staging-isolation-proof-2026-06-11.json.

D. Dry-run execution (DR-0..DR-5)

step	what	verdict
DR-0	planning validator readback	PASS
DR-1	seal-vs-bytes recheck (canon rev3 == P7 pin, 38756 B)	PASS (exact)
DR-2	stage operative blueprint doc (temp); digest cross-check	PASS (0 invented)
DR-3	stage operative-status marker (temp copy); body identity	PASS
DR-4	governance addendum + collision scan (TKT-OBJ-389..406, deconflicted from 378..395 vs concurrent T2 378..388)	PASS (0 collisions)
DR-5	reconstruct + fail-closed proof in clean temp	PASS

Every step is read-only or applied-to-temp-then-rolled-back. production_target=false. Machine form: fix7-p0-dryrun-execution-evidence-2026-06-11.json.

E. Rollback proof (staging/temp)

Staging mutation occurred (DR-2/3/4) → rollback_proof_status = PROVEN_IN_STAGING.

id	surface	before → apply → rollback	restored?
RB-2	operative blueprint doc (new)	ABSENT → `30bdca6e…` → ABSENT	YES
RB-3	canon operative-status marker	`49c386a9…` → `91c520d9…` → `49c386a9…` (38756 B)	YES (P7 verify_pin PASS)
RB-4	governance addendum (stub)	ABSENT → `1cddd95e…` → ABSENT	YES (registry untouched)

production_rollback_status = NOT_APPLICABLE (no production surface mutated; production rollback proof deferred to a separately-authorized production phase). Machine form: fix7-p0-dryrun-rollback-recovery-proof-2026-06-11.json.

F. TKT Base L0–L3

L0 FILE PASS · L1 RECONSTRUCTION PASS · L2 FAIL-CLOSED PASS · L3 GOVERNANCE PASS. level_reached=L3. No IU_TRACEABILITY_PASS, no SEMANTIC_TEXT_AS_CODE_PASS, no RELEASE_BUNDLE_PASS (L4/L5/L6 deferred; ceiling honored). Machine form: fix7-p0-dryrun-tkt-base-l0-l3-check-2026-06-11.json.

G. Bad-input probes (20)

python3 bad_input_probes.py → 20/20 fail-closed; controls_pass=True; any_fail_open=False. Covers all 20 required defect classes (missing/wrong P7, missing N8, stale planning tree, production target, production PG, REAL_RUN/QT001/permit/cutover requested, rollback-without-run, exit mismatch, missing log/hash/no-vector-pointer, orphan object, semantic Text-as-Code overclaim, impl-exec authorized, duplicate id, report-PASS-without-evidence). Machine form: fix7-p0-dryrun-bad-input-probes-2026-06-11.json.

H. Safe same-layer repair performed

The validator caught a real defect in this packet during authoring (dry-run step records missing the production:false field → 6 fail-closed conditions). It was repaired in-lane, the manifest regenerated, and gates re-run to PASS — demonstrating the validator is genuinely load-bearing (it fails closed on a real omission, not just synthetic probes).

I. Execution-readiness verdict

READY_FOR_OWNER_EXECUTION_REVIEW — dry-run passed, rollback proven in staging, TKT Base L0–L3 passes, KB reconstruct byte-exact; the only remaining blockers are owner/operator execution decisions and production scoping. The next macro a future owner decision could authorize is AUTHORIZE_IMPLEMENTATION_EXECUTION_NO_PRODUCTION (KB/governance only) and only after OPT-4 + production-surface scoping; REAL_RUN/QT001/permit/activation/repoint/ cutover/production each still require their own separate authorization. Machine form: fix7-p0-execution-readiness-review-packet-2026-06-11.json.

Standing blockers (owner/operator only)

FIX7-P0-PLAN-EXEC-AUTH-1 — owner OPT-4 (execution) not given → blocks implementation execution.
FIX7-P0-PLAN-SURFACE-1 / -SURFACE-2 — production birth surface + CI UNKNOWN; must be scoped, not invented → blocks execution + production.
FIX7-P0-PLAN-REALRUN-1 / -SEPARATE-AUTH-1 — REAL_RUN / QT001 / cutover each separate → blocks execution + production.
FIX7-P0-DRYRUN-PROD-ROLLBACK-1 — production rollback proof requires a separately-authorized production phase → blocks production.

Next macro (minimal)

Owner/operator reviews fix7-p0-post-dryrun-owner-operator-decision-packet-2026-06-11.json (default HOLD, selected_option=null, UNSIGNED). If AUTHORIZE_IMPLEMENTATION_EXECUTION_NO_PRODUCTION, route to a separately-authorized KB/governance execution macro after OPT-4 + production scoping. No production. No self-approval.
