RS-TKT-1 (Phase 1) · 21 — Phase 2 Readiness Checklist (Design-Only)

Lane: RS-TKT-1 — Phase 1 TKT Base Design Package (design-only) Date: 2026-06-22 Gate: REGISTRATION_HOLD · REGISTRATION_CAN_PROCEED = NO · 0 runtime mutations Authority: NON_AUTHORITY · may_gate=false · decision_effect=NONE

This document is NOT authorization for Phase 2. It is a checklist of what would be needed before a Phase 2 MVP read/report inspector could even be considered. Phase 2 opens only by an explicit Owner decision after GPT/Codex accept Phase 1.

---

1. Preconditions before Phase 2 may be considered

[ ] Phase 1 accepted by GPT, then by an independent Codex review.
[ ] Owner explicitly opens Phase 2 (reaching the end of Phase 1 does NOT open Phase 2).
[ ] No runtime execution authorized beyond a deny-by-default read/report surface.
[ ] Read/report-only scope confirmed (no subject-under-test execution).
[ ] An allowed INPUT folder is named (where inert packets are read from).
[ ] An allowed OUTPUT folder is named (where result.json/result.md are written).
[ ] No subject-under-test execution (that is Phase 4 + a Call Contract).
[ ] Fixture catalog accepted (12/17 positive controls + negative fixtures).
[ ] Report schema accepted (13 result.json/result.md shape).
[ ] Stop states accepted (15 §4: HOLD_NO_EXEC_SURFACE / HOLD_RUNTIME_SURFACE_REQUIRED / HOLD_OUTPUT_SURFACE_UNAVAILABLE).

2. What Phase 2 would be (scope, if opened)

Phase 2 = the FIRST runnable TKT: a read-only inspector that runs L0–L3 (+ optional RS profile) against an inert KB packet
          and emits TKT_BASE_RESULT + findings. Read/report only. Disposable workspace (delete-fast).
Until an authorized execution surface exists, Phase 2 stops at HOLD_NO_EXEC_SURFACE.

3. What Phase 2 must never do (carried from 15)

No subject-under-test execution · no PG/Directus/registry/system_issues mutation · no gate/seal · no clearing HOLD ·
no CAN_PROCEED=YES · no Owner/scope/APR/register_dot · no semantic/IU/release/implementation/runtime/production PASS.

4. Open inputs Phase 2 would need (from 20)

OD-4 implementation language/tooling · OD-5 repo/path · OD-11 confirm base pack currency.
(OD-1 root and OD-7 Call Contract are Phase 3 / Phase 4, not Phase 2.)

5. Checklist status

This is a DESIGN-ONLY checklist. Every box above is currently UNCHECKED at the authorization level
(only the design artifacts that feed them exist). Checking these boxes is a future Owner/Codex action, not a Phase-1 outcome.
Phase 1 success ⇒ the checklist EXISTS and is reviewable. It does NOT ⇒ Phase 2 is ready or authorized.
