Checkpoint — TKT Parallel Support Preflight

Authority: NON_AUTHORITY / NOT_PROMOTED / SUPPORT_LANE
Host: T2 / CLAUDE CODE / FABLE
Object: TKT-OBJ-386
Date: 2026-06-11
Final status: TKT_PARALLEL_SUPPORT_PARTIAL_T1_PENDING

Why PARTIAL (not READY)

All four safe parallel workstreams are complete as preflight/template/checklist material. The status is PARTIAL because the dry-run-specific scan waits for T1 output: T1's dry-run / execution-readiness packet is not yet published (T1_DRYRUN_NOT_YET_PUBLISHED, verified — only the paper planning packet + a staging-only dry-run design exist, execution_ready=false). No safe same-lane work remains; the review template is ready to apply the moment T1 publishes.

Workstreams

A Governance fold preflight — COMPLETE. Fold boundary=224; backlog 225..388 contiguous; collision CLEAN; orphan CLEAN; missing-pointer scan (326..342 & 343..377 absent from both pointer surfaces); ascending apply-order; APPLY_NOW=NO.
B Object collision/orphan audit — COMPLETE. Duplicate IDs=0; overlaps=0; one RESOLVED_HISTORICAL near-collision (T1 289..309→305..325); safe ceiling=388.
C TKT Base review template (FIX7 dry-run) — COMPLETE (template only). Keyed to L0–L3 + scope-leak + rollback/exec/semantic overclaim guards. Readback Table C included.
D NVSZ root readiness packet — COMPLETE (operator checklist). R0–R8 + escrow schema + byte-vs-functional + both validators' exit taxonomies + exact operator inputs + options A–E. No designation.
E Current-state — published (TKT-OBJ-387).

Evidence basis

Built from direct reads of governed files (registry JSON rev20 / MD rev22 / 00-index rev114; NVSZ designs R0–R8 + escrow; Base output-level policy L0–L3; T1 impl-planning + current-state), via 5 read-only reader passes. No report-prose-only claims for load-bearing facts.

Safety self-check (all YES unless noted)

T1/FIX7 mutation: NO · canonical registry/index fold: NO · registry-JSON/00-index rewrite: NO · NVSZ root designation: NO · production mutation: NO · REAL_RUN/QT001/apply/permit/activation/repoint/cutover: NO · N7/N8/P7 mutation: NO · semantic L4–L6 opened: NO · collision scan: complete · orphan scan: complete · review template: usable · NVSZ readiness: complete.

Objects allocated

TKT-OBJ-378..388 (PROPOSED) via standalone addendum TKT-OBJ-388. APPLY_NOW=NO.

Blockers (carried, none introduced)

TKT-SUPPORT-GOV-FOLD-1 (owner/GPT) — fold 378..388 last, at T1-quiescent safe point.
Pre-existing: V02-NVSZ-GOV-FOLD-1, TKT-BASE-GOV-FOLD-1, FIX7-P0-PLAN-GOV-FOLD-1, V02-PB-NVSZ-1, plus T1-active write-race guard.

Next step after T1 finishes

Apply the TKT Base review template to T1's published dry-run output.
Reserve T1 dry-run object range starting 389.
At T1-quiescent safe point: fresh rescan → ascending fold 225..388 per preflight (file-presence recheck at Step 0).
