10. Lifecycle and Quality Gates¶

Dense chapter: read after §6–§9; passing the QGs — guide/00; density — reference/09.

10.1 How artifacts move: statuses and gates¶

A RENAR artifact — a requirement, a specification, an ADAPT, a test — does not sit still. It moves through states: draft → approved → verified → …. And it cannot move arbitrarily: every transition is guarded by a Quality Gate — a condition that MUST be satisfied, or the transition does not happen. A requirement does not become verified until all of its tests have gone green on the current version; an ADAPT does not become approved without two signatures. A gate is not a "success checkmark" but a check that is entitled to say "no" and leave the artifact where it is.

This chapter brings together the state machines of all artifacts and normalizes the gates: what is checked before each transition, who MUST check it and when. The chapter fixes only states, transitions, and gates; artifact frontmatter is defined by chapters 6–09.

10.1.1 Decision tree: which gate now (informative)¶

10.2 Normative definition of a Quality Gate¶

10.2.1 Quality Gate¶

Quality Gate (gate) is a normative condition whose check MUST be performed for a permitted transition of an artifact from one lifecycle state to another. Each gate consists of:

Identifier — QG-N or QG-<artifact>-<state> (closed list §10.3, §10.4).
Precondition — a set of checkable assertions about the artifact and related artifacts that MUST be true at the moment the gate is triggered.
Postcondition — the state the artifact transitions into after a successful gate pass, and the observable effects (for example, the appearance of a record in the transition log §10.13).
Trigger — who or what initiates the gate check (participant: AI agent / Architect / automated runner; event: approval / run completion / arrival of a delta-TZ).
Control point — the place in the substrate where the check MUST be automated (§10.11).

A gate is not a success event — it is a condition that MUST be checked. A gate pass MAY be negative (the precondition is not satisfied) — in that case the transition is prohibited and the artifact stays in its current state.

10.2.2 Who MUST check a gate¶

Gate type	Required participant	Substrate enforcement
Approval (QG-0)	Architect or authorized role-holder on the substrate	Atomic recording of authorship and time (V6, §3.3.6)
Implementation (QG-1)	Automated runner (CI, eval-runner)	Atomic recording of the run result pinned to the artifact version (V5, §3.3.5)
Verification (QG-2)	Automated runner with `version-pin` confirmation	V5 + V6
Architecture (QG-3, optional)	Dual signature (client + Architect)	V3 + V6
Acceptance (QG-4, optional)	Stakeholder with authority	V6

10.2.3 Relationship to SENAR¶

SENAR §8 describes Quality Gates as an abstract concept for AI-driven development. RENAR extends SENAR in the requirements-engineering domain:

It keeps the identifiers QG-0 / QG-1 / QG-2 as mandatory.
It normalizes formal state machines for each artifact type (SENAR does not do this).
It binds every transition in a state machine to a concrete gate with preconditions and postconditions.
It adds optional QG-3 / QG-4 for industries with extended audit requirements.

RENAR does not contradict SENAR; an implementation is SENAR-compatible with RENAR if the requirements of §10.3 + §10.11 are met.

10.3 Canonical RENAR gates (mandatory)¶

A closed list of three mandatory gates. Extensions outside this list are only the optional ones in §10.4 or through the formal standard change procedure §10.10.

10.3.1 QG-0 — approval gate¶

Purpose: permits an artifact to transition from draft into a state approved for development.

Precondition (common part, supplemented per-artifact in §10.5–§10.9):

The artifact frontmatter is valid against the schema of its chapter.
The artifact identifier is unique in the substrate (V1, §3.3.1).
An adversarial review has been performed; or its non-applicability is explicitly recorded — permitted only for trivial artifacts (by the criteria declared in the conformance manifest, §13) with the reason recorded in the transition log (§10.13).
If the artifact references a source (source.adapt for BR/SR/SPEC, verifies[] for TC) — the referenced artifact exists in the substrate in a state no lower than approved.

Postcondition:

The artifact transitions into approved (for requirements / SPEC) or ready (for TC) or approved ADAPT (§10.8).
A record in the transition log (§10.13).
For requirements / SPEC: decomposition into child artifacts is permitted (for BR — SR; for SR — TR + SPEC via constrained-by / implements-spec).

Trigger: explicit approval by the Architect / role-holder through the substrate's native mechanism (V3 diff & review, §3.3.3).

Applicable artifacts: BR, SR, TR, SPEC, ADAPT, TC.

10.3.2 QG-1 — implementation gate (TC only)¶

Purpose: confirms that a valid implementation exists for the artifact — code, configuration, an infrastructure artifact — suitable for verification.

Precondition:

The implementation is pinned to the artifact version via version-pin (V5, §3.3.5).
automation.status: automated (with a valid automation.location) or automation.status: manual-pending (with manual-pending-until set and manual-pending-reason).
All static checks of the implementation by the substrate agent (types, lint, schema) — passed.
Pos/neg pairing for the artifact's covered assertions is ensured (chapter 9 §9.7).
All mandatory body sections of the TC (chapter 9 §9.4) are filled in.

Postcondition:

The TC transitions into ready.
A record in the transition log.

Trigger: the approving participant (one-click promote draft → ready) upon the automated runner's confirmation of a passing dry-run.

Applicable artifacts: TC (draft → ready).

Note: TR does not pass a separate QG-1 gate. The implementation-validity conditions (impl scope, version-pin, static checks) for TR are part of the QG-2 preconditions (§10.6.2). QG-1 applies only to TC. For BR / SR / SPEC the approved → verified transition is governed by a single QG-2; there is no intermediate QG-1 implementation gate for requirements and SPEC.

10.3.3 QG-2 — verification gate¶

Purpose: confirms that the system's observed behavior conforms to the artifact: all TCs in the artifact's verified-by are in state passing on the artifact's current version.

Precondition:

For BR / SR / SPEC: all TCs in verified-by have last-run.result = pass, and last-run.requirement-version (or the equivalent spec-version / version) matches the current version of the verified artifact.
Pos/neg pairing on the artifact's normative assertions — satisfied.
All mandatory spec-specific TC kinds for the artifact type are present (chapter 9 §9.8).
For TR: all its AC are verified by bound TCs (last-run.result = pass).
Spec-specific additional preconditions:
SPEC-UI / SPEC-AI: TC in state passing with judge-isolation observed (chapter 9 §9.13.4).
SPEC-SEC: a TC tc-type: security is present and passing.

Postcondition:

The artifact transitions into verified.
A record in the transition log with evidence-refs (a list of run IDs).
The substrate MUST record the version of the verified artifact in the evidence record (V5).

Trigger: the automated runner confirms passing TCs and initiates the promote-transition on the author's request (one-click promote approved → verified).

Applicable artifacts: BR, SR, SPEC, TR.

10.4 Optional gates¶

QG-3 and QG-4 are normatively described but not mandatory for conformance (chapter 13). An implementation MAY declare in the conformance manifest either support for QG-3 / QG-4 or their absence. Conformance without QG-3 / QG-4 remains valid.

10.4.1 QG-3 — architecture gate (optional)¶

Purpose: permits an ADAPT to transition from answered to approved (§10.8). Also applicable to SPEC-ARCH decomposition decisions in projects with regulated architectural acceptance.

Precondition:

All backward findings in the ADAPT are in status resolved (chapter 7 §7.4.5).
The dual signature is ready: client signature + Architect signature (chapter 7 §7.5).
For SPEC-ARCH (if QG-3 is applied): the decomposition decision is recorded in the substrate as an ADR-like artifact with a reference from the SPEC-ARCH (the ADR form is substrate-specific — fits in guide/).

Postcondition:

The ADAPT transitions into approved (immutable, on a par with the TZ).
A record in the transition log with both signatures (V6 author + timestamp records both participants).

Trigger: explicit dual approval; the substrate MUST atomically record both signatures (V2 atomic change unit, §3.3.2).

When to apply:

ADAPT — always (but an implementation MAY declare QG-3 as a local alias for ADAPT approval, without carving it out as a separate gate).
SPEC-ARCH — in projects with regulatory requirements for architectural acceptance.

10.4.2 QG-4 — acceptance gate (optional)¶

Purpose: records the client's acceptance of the business outcome after release. The transition of a BR from verified to accepted.

Precondition:

BR in verified (QG-2 passed).
The measurable business outcome (business-outcome in the BR frontmatter) — measured; current-value recorded.
achievement ≥ the project-configurable threshold (80% by default, fixed in the conformance manifest).
A formal Stakeholder signature.

Postcondition:

The BR transitions into accepted (a terminal non-degradable status — a reverse transition requires a delta-TZ).
A record in the transition log with the Stakeholder signature.

Trigger: formal acceptance by the Stakeholder upon release.

When to apply:

Projects with explicit recording of post-release outcomes (product SaaS, regulated industries).
In the absence of QG-4 — the accepted status is not used; the BR stays in verified until deprecated.

10.4.3 Conformance with optional gates¶

The conformance manifest (chapter 13) MUST explicitly declare:

quality-gates:
  qg-0: required          # always required
  qg-1: required
  qg-2: required
  qg-3: declared          # required | declared | absent
  qg-4: declared

declared means: the implementation supports the gate; artifacts MAY pass it, but conformance does not require passing it for all artifacts. absent — the gate is not applied in the implementation; the artifact's terminal state is verified (without accepted).

10.5 BR / SR state machine¶

10.5.1 States and transitions¶

draft  ──[QG-0]──▶  approved  ──[QG-2]──▶  verified  ──[QG-4 (optional)]──▶  accepted
  │                     │                      │                                    │
  │                     │                      │                                    │
  └──────────┬──────────┴──────────────────────┴──────────[deprecation]─────────────┘
             ▼
        deprecated  (terminal; with `replaced-by` if there is a replacement)

Status	Semantics	Transition gate
`draft`	Created by an AI agent or the Architect; not yet approved	— (creation)
`approved`	Approved for decomposition / implementation	QG-0 (§10.3.1)
`verified`	All derived TCs `passing` on the current version	QG-2 (§10.3.3)
`accepted`	Post-release business outcome confirmed	QG-4 (§10.4.2, optional)
`deprecated`	Terminal; not deleted (V1 immutable history)	Deprecation transition (§10.5.3)

BR / SR frontmatter (including the mandatory status fields) is defined in chapter 6 §6.5.2 / §6.6.2. This section normalizes only the transitions between states and the binding to gates.

10.5.2 Per-transition preconditions¶

Transition	Gate	Additional preconditions (on top of §10.3)
`draft → approved`	QG-0	BR: `business-outcome` filled in. SR: the `parent` BR in a state no lower than `approved`. If the SR references a SPEC via `constrained-by[]` — all SPECs in `approved` or higher.
`approved → verified`	QG-2	At least one TC with `negative: true` in `verified-by`. All `last-run.requirement-version` match the current `version`.
`verified → accepted`	QG-4	Only if the implementation declared QG-4.
`* → deprecated`	Deprecation transition (§10.5.3)	See §10.5.3

10.5.3 Deprecation transition¶

Precondition:

The artifact is in any non-deprecated state.
replaced-by (if specified) exists in the substrate and is in a state no lower than approved.
There are no active child TRs in state approved and no active implementer tasks on this artifact (atomic re-pointing of tasks to the replacement is a mandatory condition, V2 atomic change unit).

Postcondition:

status: deprecated.
deprecated-date recorded (V6).
replaced-by specified, if there is a replacement.

Trigger: the Architect or the Product Owner.

10.5.4 Reverse evolution of verification¶

If an artifact is already verified but its version has been incremented (for example, after applying a delta-ADAPT, chapter 7 §7.6) — the status MUST revert to approved before re-passing QG-2 on the new version. This transition is mandatory and automatic: the substrate MUST invalidate verified upon a change of version (chapter 6 §6.5.4 reverse evolution).

10.6 TR state machine¶

10.6.1 States and transitions¶

draft  ──[QG-0]──▶  approved  ──[QG-2 (per TR)]──▶  done
  │                     │                            │
  │                     │                            │
  └─────────────────────┴───[deprecation]───────────▶ obsolete

Status	Semantics	Gate
`draft`	TR created; AC not yet finalized	—
`approved`	AC approved; implementer work may start	QG-0 (§10.3.1) with the TR preconditions from §10.6.2
`done`	AC verified; all bound TCs `passing`	QG-2 (§10.3.3) with the TR preconditions from §10.6.2
`obsolete`	TR has lost relevance before completion (the parent SR changed)	Deprecation (Architect)

10.6.2 Preconditions for TR¶

QG-0 for TR (draft → approved) — in addition to the common part:

A goal is stated (goal).
AC are verifiable and independent (each AC is a separate check).
At least one negative scenario is present.
A reference to the parent SR (or BR for simple configurations) is established via implements.
If the TR implements a SPEC — the mandatory field implements-spec[] (chapter 8 §8.6.2).
If the task touches security — threat-surface is declared (chapter 8 §8.5.8).

QG-2 for TR (approved → done):

All TR AC are confirmed by the passing of corresponding TCs (last-run.result = pass).
Pos/neg pairing for each AC.
For a TR implementing a SPEC: a TC of the corresponding spec-specific kind exists and is passing (chapter 9 §9.8).

10.6.3 TR deprecation¶

If the parent SR transitions into deprecated or its version has changed such that the TR's AC are no longer relevant — the TR transitions into obsolete. This is not degradation — it is an alternative terminal path. A TR in obsolete is not deleted.

10.7 SPEC state machine¶

10.7.1 States and transitions¶

draft  ──[review-transition]──▶  review  ──[QG-0]──▶  approved  ──[QG-2]──▶  verified
                                                          │                       │
                                                          └───[deprecation]──▶ obsolete  (terminal)

Status	Semantics	Gate
`draft`	SPEC created; mandatory frontmatter fields being filled in	—
`review`	Mandatory body sections (§8.4.1) and type-specific ones (§8.5) present; ready for review	Review-transition (§10.7.2)
`approved`	Architect confirmed; `depends-on[]` consistent	QG-0
`verified`	All mandatory spec-specific TCs `passing`	QG-2
`obsolete`	Replaced or no longer relevant; `replaced-by` mandatory	Deprecation (§10.5.3 mutatis mutandis)

10.7.2 Review-transition (`draft → review`)¶

The review-transition is not a full-fledged gate in the sense of §10.2.1 — it is an automatic check of structural completeness. Precondition:

All mandatory frontmatter fields §8.4 are filled in.
All mandatory body sections §8.4.1 are present.
Type-specific sections §8.5 are present for the corresponding spec-type.

Postcondition: status: review; the artifact is visible to the Architect for review.

If the review-transition is not passed — the artifact stays in draft; the substrate MUST return the list of missing sections (V3 diff & review supports structural feedback).

10.7.3 Preconditions for SPEC¶

QG-0 for SPEC (review → approved) — in addition to the common part §10.3.1:

The depends-on[] graph is acyclic (chapter 8 §8.6.3).
All SPECs in depends-on[] are in a state no lower than approved.
If the SPEC references an ADAPT via source.adapt — the ADAPT is in state approved.

QG-2 for SPEC (approved → verified):

All mandatory spec-specific TC kinds for the spec-type are present and passing (chapter 9 §9.8).
For SPEC-AI: pos/neg pair coverage over evaluation-criteria = 100%; judge-isolation observed.
For SPEC-SEC: tc-type: security is present.
For SPEC-DATA: tc-type: contract is present for published interface fields.

10.8 ADAPT state machine¶

10.8.1 Macro-states¶

draft  ──[review-transition]──▶  review  ──[backward-ready]──▶  client-ready
                                                                       │
                                                                       │ [client returns answers]
                                                                       ▼

                                                                       │
                                                                       │ [QG-3]
                                                                       ▼
                                                                  approved
                                                                       │
                                                                       │ [immutable; only delta-ADAPT / errata / supersession]
                                                                       ▼
                                                                  frozen ──[supersession: §10.8.5]──▶ superseded
                                                                                                        (terminal)

The ADAPT states (draft → review → client-ready → answered → approved → frozen, and the terminal superseded upon supersession) are defined in chapter 7 §7.4 and §7.6.4. This section normalizes the gates.

Transition	Gate	Precondition
`draft → review`	Review-transition	The Forward interpretation covers all TZ sections; the primary backward findings are recorded in `open`
`review → client-ready`	Backward-ready	All backward findings moved to `asked-to-client`; the question package is formed
`client-ready → answered`	Client-return	All backward findings in `answered` with author + timestamp of the client's answer (V6)
`answered → approved`	QG-3 (§10.4.1)	All backward findings in `resolved`; the dual signature is ready
`approved → frozen`	Freeze-transition	Automatic after approve; the ADAPT is immutable; generation of BR / SR / SPEC with `source.adapt = approved` is permitted
`frozen → superseded`	QG-3 of the superseding ADAPT (§10.8.5)	The superseding ADAPT (`supersedes: ADAPT-MMM`) has reached `approved`; derived BR / SR / SPEC are re-pointed or re-derived

10.8.2 Nested state machine for a backward-finding record¶

Each backward-finding record inside an ADAPT has its own subordinate state machine (chapter 7 §7.4.5):

open  ──▶  asked-to-client  ──▶  answered  ──▶  resolved  ──[approve ADAPT]──▶  frozen
                  ▲                  │
                  └──── revised ─────┘  (if the answer requires clarification)

Sub-state	Semantics
`open`	Recorded by the Engineer; not sent to the client
`asked-to-client`	Sent to the client; the question date is recorded
`answered`	The client answered; the answer recorded (V6 author + timestamp)
`resolved`	The Engineer integrated the answer into the Forward interpretation
`revised`	The answer is vague; a repeat question (return to `asked-to-client`)
`frozen`	After ADAPT approval; changes are impossible

Normative rule: QG-3 (approve ADAPT) is prohibited if at least one backward-finding record is in open / asked-to-client / answered / revised. All such records MUST be in resolved (chapter 7 §7.4.5).

10.8.3 QG-3 for ADAPT — detailed¶

Precondition (full):

All Forward-interpretation sections are filled in (the forward-complete criterion).
All backward-finding records in resolved.
The client signature obtained and recorded by the substrate's native mechanism (V3 + V6).
The Architect signature obtained and recorded.
If the ADAPT is a delta-ADAPT: the parent-ADAPT in frozen (chapter 7 §7.6).

Postcondition:

The ADAPT transitions into approved.
A record in the transition log with both signatures.
The substrate MUST atomically (V2) record both signatures: a partial signature (client only / Architect only) does not transition the ADAPT into approved.

Trigger: explicit approval by both participants.

10.8.4 Errata for a frozen ADAPT¶

frozen is a terminal state along the derivation line. Changes are possible only by adding a new artifact via one of three paths:

Delta-ADAPT (if the TZ contains an ambiguity discovered late) — a new artifact with an explicit parent-adapt link.
Errata-ADAPT (if there is an interpretation error by the engineer) — a separate artifact with the client signature (if the contractual outcome changes) or the Architect's alone (if cosmetic).
Supersession (if the prior decision was correct but later refuted) — a superseding ADAPT transitions the superseded one into superseded (§10.8.5, chapter 7 §7.6.4).

In all three cases the frozen ADAPT is not edited. This is a V1 requirement (immutable history) for contractual artifacts (chapter 7 §7.6.3).

10.8.5 The frozen → superseded transition (supersession)¶

Supersession of an approved/frozen ADAPT is normalized in chapter 7 §7.6.4. The lifecycle transition:

frozen ──[superseding ADAPT reached approved via QG-3]──▶ superseded (terminal, immutable)

No separate QG is introduced. Supersession goes through the same QG-3 (dual signature, §10.8.3) as an ordinary ADAPT — no additional control point is created.

Precondition of the ADAPT-MMM → superseded transition:

A superseding ADAPT-NNN has been created with the field supersedes: ADAPT-MMM and a non-empty supersession-rationale (chapter 7 §7.6.4).
The superseding ADAPT has passed QG-3 and reached approved. If the superseded decision had a contractual outcome (the typical case) — the dual signature MUST include the client signature; the Architect signature alone is permitted only for a strictly cosmetic correction without a contractual outcome.
All derived BR / SR / SPEC with source.adapt: ADAPT-MMM are re-pointed to the superseding ADAPT or re-derived (no dangling references).

Postcondition:

ADAPT-MMM transitions into the terminal superseded — distinct from obsolete and from frozen; immutable and retained for audit (V1), not deleted.
The field superseded-by: ADAPT-NNN on ADAPT-MMM is recorded automatically.
A record in the transition log with the signatures of the superseding ADAPT (V6).

Trigger: approval of the superseding ADAPT via QG-3.

Hook obligation: after the transition, a dangling source.adapt reference to an ADAPT in status superseded is fatal; enforcement — the adapt-supersession validation (§10.11.1), the check-adapt-supersession.js gate.

10.9 TC state machine¶

10.9.1 States and transitions¶

draft  ──[QG-0]──▶  ready  ──[runner pass]──▶  passing

                                                obsolete  ◀─────┘  (terminal)

Status	Semantics	Gate / trigger
`draft`	TC created; implementation in progress	—
`ready`	dry-run runner passed; pos/neg pairing confirmed	QG-0 (§10.3.1) with the TC preconditions from §10.9.2
`passing`	`last-run.result = pass` on the current `requirement-version`	runner pass; bot-managed
`failing`	`last-run.result = fail`	runner fail; bot-managed
`obsolete`	The covered behavior no longer exists	Deprecation (§10.9.4)

TC frontmatter and pos/neg pairing are defined in chapter 9.

10.9.2 Preconditions for TC¶

QG-0 for TC (draft → ready) — in addition to the common part:

automation.status: automated (with a valid automation.location) OR automation.status: manual-pending (with manual-pending-until ≤ +1 sprint and a filled-in manual-pending-reason).
Pos/neg pairing over the covered assertions confirmed (§9.7).
The dry-run runner passed (structural validity only; not to be confused with a production run).
All mandatory body sections of the TC (§9.4) are filled in.
The citation in verifies[] — the artifact exists in the substrate in a state no lower than approved.

Postcondition:

status: ready.
The runner is permitted to do a production run.

10.9.3 Runner-managed transitions (not Quality Gates)¶

ready → passing, ready → failing, passing → failing, failing → passing — transitions that happen only upon a runner run (chapter 9 §9.12 last-run bot-managed). These transitions are not Quality Gates in the sense of §10.2.1: they are normative consequences of run results, not the passing of a gate with preconditions and postconditions. In particular, the check that last-run.requirement-version matches the current version of the verified artifact (see §9.10) is a runner-managed consistency check, not a separate gate.

Postcondition of each runner transition:

last-run updated: result, timestamp, requirement-version, evidence-refs.
The substrate MUST prohibit manual modification of last-run (runner-actor only).

10.9.4 TC deprecation¶

A TC transitions into obsolete if:

An artifact in verifies[] transitions into deprecated / obsolete.
A delta-TZ invalidates the test behavior (chapter 9 §9.16).

Postcondition: status: obsolete. The TC is not deleted (V1 immutable history).

10.9.5 Change-of-criteria — a separate normative path¶

Changing ## Pass criterion or ## Fail criterion in a TC is not an ordinary transition; it is a special path that requires a separate approval workflow (chapter 9 §9.13). Enforcement details — §10.11.3.

10.10 Closed-list policy¶

10.10.1 Normative rule¶

The closed list of RENAR Quality Gates is the mandatory {QG-0, QG-1, QG-2} and the optional {QG-3, QG-4}. Changing the list is possible only through the formal RENAR Standard change procedure (chapter 13).

This policy is a specialization of §1.7 Closed-list policy for Quality Gates; the general rule for all RENAR closed lists and the master index — §1.7.5.

10.10.2 What is prohibited¶

Action	Prohibited?	Why
Locally creating a new gate type `QG-N` at the project level	Prohibited	Violates the closed list; makes conformance non-portable
Locally overriding the preconditions of a canonical gate	Prohibited	Makes conformance incomparable across implementations
Additionally tightening the preconditions of a local gate	Permitted	The conformance manifest MAY declare stricter thresholds (for example, `qg-2.required-negative-tc: true`)
Locally weakening the preconditions of a canonical gate	Prohibited	Violates the standard's contract
Declaring QG-3 / QG-4 as `absent` in the conformance manifest	Permitted	Optional gates — §10.4
Declaring QG-0 / QG-1 / QG-2 as `absent`	Prohibited	Violates conformance §10.4.3

10.10.3 Extending the list¶

Adding a new gate type is possible through:

A standard change request with a rationale — a research draft with a typology and a comparison with the canonical gates.
Public review (the period and forum are fixed by the standard policy, chapter 13).
Inclusion in the next minor version of the standard (v1.X or v2.0).

Project-local extensions remain outside conformance — they are permitted as internal practices but do not affect the conformance manifest.

10.11 Substrate-independent enforcement¶

10.11.1 Normative requirements¶

A substrate implementing RENAR MUST ensure an automatic check of gate preconditions at the following points:

Control point	What MUST be checked	Relies on capabilities
Promote-transition (any transition to a higher status)	The preconditions of the corresponding gate (§10.3, §10.4, §10.5–§10.9)	V3 (diff & review) to block the transition until approve; V4 (branching) to separate WIP from the approved truth
Approve-transition (any approval action)	Authorship recorded (actor) and timestamp	V6 (author + timestamp)
Reference-validation (any creation/change of an artifact with a reference to another)	The referenced artifact exists and is in the required state	V1 (immutable history) for a stable identifier; V5 (version pin) for cross-substrate references
Change-of-criteria for TC (§10.11.3)	A separate approval process is applied	V3 + V6
Runner-transitions for TC (`ready → passing`/`failing`)	Only the runner-actor may write `last-run`	V6 (authorship); the substrate's native ACL or role-based restrictions
Lifecycle invalidation (artifact `verified`, version incremented)	The artifact is automatically reverted to `approved`	V5 (version pin) for detection
`implements`-edge validation (subsystem BR referencing a system BR, §6.5.2, §6.8.2)	(1) the target BR exists by `id + scope.system`; (2) the target in `approved`+ at the approval of this BR (a `deprecated` target — warning, not fatal; cascade-warning over `implemented-by[]`); (3) the `implements` chain forms no cycles; (4) `implements[]` is absent when `level: system`	V1 (stable identifier for target lookup); V3 (block approve until validation passes); V5 (cross-substrate ID resolution when the target is in another substrate)
`adapt-applicability` validation (§7.4.1)	(1) For each TZ, an adversarial-review verdict is recorded (V6 author + timestamp). (2) If the verdict is "findings present" — a corresponding ADAPT MUST exist in `approved`+ with a dual signature; the BR/SR/SPEC derivatives have `source.adapt`. (3) If the verdict is "no findings, no clarifications" — no ADAPT, and the BR/SR/SPEC have `source.tz-section` + `source.adversarial-review-ref` evidence. (4) No mixing: artifacts with `source.adapt` omitted without verdict evidence — fatal.	V3 (block approve until validation passes); V6 (verdict + signature attribution); V1 (verdict as immutable evidence)
`adapt-supersession` validation (§7.6.4, §10.8.5)	(1) `supersedes: ADAPT-MMM` references an existing ADAPT; the back-reference `superseded-by` is symmetric. (2) `supersession-rationale` is non-empty and references a concrete contradicting `BR` / `SR` / `SPEC`. (3) When the superseded decision has a contractual outcome — the superseding ADAPT has the client signature. (4) A dangling `source.adapt` reference to an ADAPT in status `superseded` — fatal.	V1 (stable identifier + immutable superseded history); V3 (block approve until validation passes); V6 (signature attribution)

10.11.2 A substrate without V3 / V4 / V6 is non-conformant¶

A substrate that does not provide V3 (diff & review) cannot implement gates: there is no way to separate a "proposed change" from the "approved truth" (chapter 3 §3.3.3). The same holds for V4 (branching, §3.3.4) and V6 (author + timestamp, §3.3.6) — without them the approval mechanics are impossible. A substrate that does not satisfy V3 / V4 / V6 does not implement RENAR regardless of other properties.

10.11.3 Change-of-criteria for TC — special enforcement¶

Changing the Pass / Fail criterion of a TC is a high-risk operation (protection against test-fitting, chapter 9 §9.13). The substrate MUST:

Detect: any change to the ## Pass criterion / ## Fail criterion sections in a TC artifact.
Forcibly isolate: a change-of-criteria MUST be a separate change-set (V4 atomic change unit), marked with a flag distinguishing it from ordinary edits (the substrate's native mechanism — a special case of V3 diff & review; the form of the flag is substrate-specific, deferred to guide/).
Prohibit combining: the same person MUST NOT approve both a change-of-criteria and the approval of a code fix that is tested by this same TC. The substrate MUST check this rule at the approve-transition.
Register: a change-of-criteria is recorded in the audit trail (§10.13) with explicit event typing.

10.11.4 Forms of substrate-native implementation¶

The concrete substrate-native mechanisms (how exactly a hook is implemented in a given substrate) are deferred to guide/ and the conformance manifest. The standard does not normalize the form of a hook (this is a substrate-specific decision). The standard normalizes what a hook MUST check and at which point.

The guide/ section MUST contain, for each supported substrate:

A mapping of the enforcement points of §10.11.1 onto the substrate-native mechanisms.
Example implementations.
The known limitations of the substrate regarding the automation of each check.

10.12 Prohibited transitions¶

A closed list of transitions that violate the lifecycle. The substrate MUST block them.

From	To	Artifact	Why prohibited
`draft`	`verified`	BR / SR / SPEC	Skips QG-0; no approval evidence
`draft`	`accepted`	BR	Same; and skips QG-2
`draft`	`done`	TR	Skips QG-0
`draft`	`passing`	TC	Skips QG-0 (no dry-run runner)
`obsolete`	*	Any	Terminal status; "resurrection" is prohibited — a new artifact with `supersedes` is needed
`deprecated`	*	Any	Same
`frozen`	*	ADAPT	Same; changes only through a delta-ADAPT or errata (§10.8.4)
`verified`	`draft`	BR / SR / SPEC	Degradation across several steps — potential loss of trace; if rework is needed — `verified → approved` via delta or reverse evolution §10.5.4
`accepted`	`verified`	BR	Degradation after acceptance — impermissible without a delta-TZ
`accepted`	`approved`	BR	Same
`passing`	`draft`	TC	Degradation loses run history; use `passing → failing → obsolete` or the change-of-criteria path
`ready`	`draft`	TC	Degradation loses dry-run evidence (§10.9.2); weakening a TC via `[test-spec-change]` (chapter 9 §9.13) — is not a path back to `draft`
`failing`	`draft`	TC	Degradation loses runner history; re-diagnosis is via a new run (`failing → passing` runner-managed) or `obsolete`

10.12.1 Substrate reaction¶

On an attempt at a prohibited transition the substrate MUST:

Block the transition (V3 diff & review).
Return to the calling participant an error code indicating the concrete violated rule (by the row identifier of this table).
Not create a record in the transition log (§10.13).

10.13 Logging of gate-pass events¶

10.13.1 Normative requirement¶

Every successful gate pass (of any type: QG-0, QG-1, QG-2, QG-3, QG-4, runner-transition, deprecation, freeze-transition) MUST be recorded in the substrate as an immutable event with the following fields:

Field	Semantics	Obligation
`timestamp`	UTC ISO-8601 moment of the successful pass	Mandatory
`artifact-id`	Artifact identifier (immutable, V1)	Mandatory
`artifact-type`	`BR` / `SR` / `TR` / `SPEC-<type>` / `ADAPT` / `TC`	Mandatory
`artifact-version`	Artifact version at the moment of the transition (V5)	Mandatory
`from-status`	Source state	Mandatory
`to-status`	Target state	Mandatory
`gate-id`	`QG-0` / `QG-1` / `QG-2` / `QG-3` / `QG-4` / `deprecation` / `freeze` / `runner-pass` / `runner-fail` / `change-of-criteria`	Mandatory
`actor`	Initiator identifier (V6); for a dual signature — a list of participants	Mandatory
`evidence-refs`	References to evidence: runner run IDs, adversarial-review artifact IDs, signature IDs	Mandatory for QG-2 / QG-3 / QG-4
`notes`	Free text	Optional

10.13.2 Substrate-independent format¶

The event-storage format is substrate-specific (a separate log stream / append-only collection / other forms). The standard normalizes only the mandatory fields of §10.13.1, not their serialization.

The conformance manifest MUST specify the event-storage mechanism and the export format (for audit, chapter 13).

10.13.3 Retention¶

Events are not deleted throughout the entire artifact lifecycle and after its transition into deprecated / obsolete / frozen. This is required by V1 (immutable history) and the normative compliance clauses (chapter 13).

10.14 Relationship to other chapters¶

Chapter	Relationship
02	SENAR QG-0..QG-2 — the conceptual basis; RENAR extends it (§10.2.3)
06	frontmatter and body of BR / SR / TR (§6.5–§6.7); the state machines are detailed here (§10.5–§10.6)
07	ADAPT frontmatter (§7.8); backward sub-states (§7.4.5); dual signature (§7.5); delta-ADAPT (§7.6) — the state machine is here (§10.8)
08	SPEC frontmatter (§8.4); type-specific QG (§8.8); the state machine is here (§10.7)
09	TC frontmatter (§9.3); pos/neg pairing (§9.7); change-of-criteria (§9.13); the state machine is here (§10.9)
03	V1–V6 — the foundation of enforcement (§10.11); without V3 / V4 / V6 — no gate implementation
11	The maturity levels determine the scope of applicable gates (for example, RENAR-1 — QG-0 / QG-1 / QG-2 mandatory; at higher levels the QG-2 preconditions are strengthened: pos/neg pairing, spec-specific TC)
13	The conformance manifest declares gate support (§10.4.3); holds the event retention policy (§10.13.3)
