Gate-typing migration is an untracked obligation
Severity: Major
Problem
The ADR requires every gate to eventually declare a risk type, while untyped gates fail closed, but supplies no referenced migration artifact or accountable owner for completing the existing gate inventory.
How to reproduce
- Read the Negative / risk consequences. 2. Follow references in the ADR and added DESIGN.md entry. 3. Observe that no migration plan, backlog item, gate inventory, owner, or schedule is identified.
Expected behavior
The ADR should link the gate-typing migration to a concrete tracked artifact that scopes the existing gate surface and ownership.
Actual behavior
The obligation is stated only as future work in the ADR.
Untyped existing gates
|
v
Fail-closed blocking behavior
|
v
No tracked migration inventory or owner
|
v
Indefinite incomplete migration
Impact
Legacy gates can remain conservatively blocked indefinitely, leaving the declared-risk model only partially deployed.
Suggested correction
Add a reference to a tracked migration feature, decomposition, or backlog item that enumerates gates, assigns ownership, and defines completion milestones.
How to verify
Confirm the ADR link resolves to a tracked artifact containing the gate inventory, owner, and migration completion criteria.

Fixed — and overtaken by events while this PR was open.
The gate-typing lint is now implemented in #153 (closing #152). It freezes the existing undeclared gates in a named baseline and fails CI on a newly introduced one, so the untyped surface cannot grow while the existing set migrates, and completion is measurable as that baseline shrinking to empty. The ADR now references it.
One thing I have deliberately not claimed: the ADR still does not assign a per-gate owner or schedule. That belongs with the workflow owners rather than in an architecture record, and the ADR now says that explicitly instead of leaving the obligation looking fully discharged.

Re-verified against the current code (9dfa444) and this is still an issue. reviewer:claude-sdk=PASS -- The ADR explicitly acknowledges the migration is unscoped: it states the lint (#152/#153) freezes the existing undeclared-gate baseline and prevents growth, but 'what this decision does not fix is a schedule or an owner per gate, which belongs with the workflow owners rather than in an ADR.' There is no linked backlog item, feature doc, or DECOMPOSITION entry enumerating the gate inventory or a timeline anywhere in this diff (unlike ADR-0018, which is referenced by name with a precise scope boundary), so the obligation is stated with tracked containment (the lint baseline) but no migration plan or owner.; reviewer:codex-sdk=FINDING -- The ADR explicitly says the lint baseline is tracked in #152/#153, but also states that no schedule or owner exists for migrating the existing gate inventory and supplies no linked migration plan, feature, or decomposition.; verifier:codex-sdk=FINDING -- The ADR explicitly says the inventory has no schedule or owner per gate and references only lint issues #152/#153, not a tracked migration plan that enumerates gate owners and a completion timeline.

Fair — "belongs with the workflow owners" was not a tracked artifact.
The obligations are now enumerated on #128, the parent issue for this work, rather than in a new tracker duplicating it: the untyped tail and how completion is measured, the five kit files outside the freeze's roots, and the retire-or-bind work with its required test.
What I have deliberately not claimed there is a per-gate owner or a schedule. Better visibly unassigned than invented in an architecture record.
Two corrections to the ADR while I was in it, both instances of the over-claim this document elsewhere avoids: the freeze is a test, not the lint — the lint only checks that a TYPE present in source is one of three literals — and #152 and #153 are both open, so nothing of it runs in CI yet. The text said otherwise in the present tense. I also added the kit gap there: five tracked files under .bootstrap/config/kits/sdlc/ sit outside the freeze's roots, and outside PDSL CI entirely.

Re-verified against the current code (cca3cc1) and this is still an issue. reviewer:claude-sdk=PASS -- The ADR does not hide this gap: the Negative/risk section explicitly names PR #152 (proposal) and open PR #153 (implementation) tracking the freeze/lint mechanism, and then explicitly states 'Two things this decision does not fix: a schedule or an owner per gate... and kit menus... outside PDSL CI entirely' — i.e. the ADR itself discloses that no full migration schedule/owner exists, rather than silently omitting it, so there is no undisclosed obligation to flag.; reviewer:codex-sdk=FINDING -- The ADR names #152/#153 only for a lint and frozen-baseline test, then expressly leaves the migration without a per-gate owner or schedule; no migration plan, feature, or dated backlog is linked for completing the existing gate inventory.; verifier:codex-sdk=FINDING -- The ADR names #152/#153 only for a lint and a frozen untyped-menu baseline, then expressly states that it provides neither a schedule nor an owner per gate; it supplies no migration plan or timeline for typing the existing gate inventory.

Now tracked concretely rather than deferred to "the workflow owners".

Re-verified against the current code (f51ea05) and this is still an issue. reviewer:claude-sdk=PASS -- The ADR's Negative/risk consequence section (architecture/ADR/0023...:141-146) explicitly names a tracked mechanism (#152/#153, with a specific test test_the_untyped_menu_surface_does_not_grow freezing the undeclared-gate baseline) and explicitly states what is NOT fixed (a schedule or owner per gate, and kit menus outside the baseline) rather than leaving the migration obligation as an unstated aspiration; this is a deliberate, disclosed scoping decision, not an undisclosed gap.; reviewer:codex-sdk=FINDING -- The ADR names open PR #153 only for a lint and frozen undeclared-gate baseline, then explicitly leaves the gate-typing migration without a schedule or owner; it provides no tracked migration plan or timeline for reducing that baseline to zero.; verifier:codex-sdk=FINDING -- The ADR names #152/#153 only for a lint and frozen undeclared-gate baseline, but expressly leaves the migration without a per-gate owner or schedule; it therefore does not provide a tracked plan to complete the required typing inventory.

Partly closed, and I will not claim more than that.
Two of the three things your How to verify asks for exist: the inventory is
tracked on #128, and completion is measurable as the frozen baseline reaching
empty — #153 adds the test that freezes today's undeclared set and fails on a
newly added one, so the surface can only shrink.
The third — an owner, and a target — is not a document edit and I have not
invented one. The record says plainly that no per-gate owner or schedule is
assigned, and the gap table names what closes it: a planning act on the tracked
inventory, proven by an owner and a target recorded against it and the baseline
reaching empty. That needs a person to decide, not a paragraph.

Undeclared-gate fail-closed behavior has no enforcement mechanism
Severity: Major
Problem
The safety-critical default is specified only as prose. The sole implementation follow-up named in the ADR is a lint with a frozen baseline for newly added undeclared gates; that lint cannot make legacy or baseline gates behave as blocking at runtime, nor does the ADR identify a runtime check or schema default that does.
How to reproduce
- Enable the default-flip implementation while legacy MENU blocks remain undeclared in the frozen baseline.
- Route one such MENU through autonomous handling.
- No mechanism identified by the ADR supplies blocking semantics for the absent declaration.
- The gate can retain overlay/runtime-derived autonomous behavior despite the stated default.
Expected behavior
Every MENU without an explicit risk constant is mechanically classified as blocking before autonomous resolution is considered.
Actual behavior
The diff names only documentation and a lint preventing growth of untyped gates; it identifies no runtime or schema enforcement of the blocking fallback.
undeclared MENU
|
v
lint baseline permits existing gate
|
v
no stated runtime fallback
|
v
autonomous path may resolve it
Impact
Existing kits and legacy gates can become more autonomous when the default flips, defeating the ADR's fail-closed compatibility boundary.
Suggested correction
Add a runtime/parser default that assigns blocking when the risk constant is absent, reject autonomous resolution unless the parsed type permits it, and reference the enforcing path and CI coverage from the ADR.
How to verify
Add tests covering an undeclared MENU in autonomous mode and assert that it stops for fresh explicit authorization; verify the runtime check is exercised for both core workflows and kits.
There was a problem hiding this comment.
Conceded, and my original answer was wrong rather than incomplete — so it is rewritten, not defended.
I had argued the contract was "not yet violable" because nothing consumes a declared type. The first half is true; the conclusion is not. Two shipped paths already resolve undeclared gates by runtime judgement, and neither reads a declaration:
skills/studio/modules/gates/simple-mode-rules.md:19— assistant mode's own auto-selection rule, no overlay involvedworkflows/brave-new-world.md— the autonomy overlay
So an undeclared gate is not fail-closed today. Recording the decision changes that in neither direction, and a lint over source cannot bind either path.
Three things changed as a result. The ADR states the position plainly instead of implying the gap is theoretical. The retirement obligation now covers assistant mode's rule as well as the overlay — the mode table marks assistant "unchanged", which is true of its narration and false of its auto-selection. And the obligation, with the test that an omitted type produces blocking behaviour, is enumerated on #128.
This also removed a self-contradiction: the compatibility-boundary paragraph already said the overlay resolves undeclared gates, which could not both be true. Your finding is stronger than the version I first answered — the default is contradicted by shipped behaviour, not merely unenforced, which makes the retirement mandate load-bearing.
There was a problem hiding this comment.
Re-verified against the current code (cca3cc1) and this is still an issue. reviewer:claude-sdk=PASS -- The ADR itself states plainly that no enforcement exists yet: 'Nothing in Studio reads a declared type today, so nothing yet resolves a gate by declaration' and 'Enforcement — and a test asserting that an omitted type produces blocking behaviour — belongs with the change that introduces declaration-driven resolution, because that is the change that can bind these two paths; a lint over source cannot.' It explicitly names the gap (the overlay and assistant-mode auto-selection still resolve undeclared gates by runtime judgement) and defers the enforcing mechanism to a future change rather than claiming one exists now, and separately notes only the declaration lint (present-TYPE-is-one-of-three-literals) is tracked in PR #153/#152 with a baseline-freeze test — which checks declaration hygiene, not fail-closed default behavior. This is consistent, not a hidden gap: the ADR is honest that the safety of the rollout currently rests on documentation plus narrow/reviewed existing paths until the follow-up change lands.; reviewer:codex-sdk=PASS -- The ADR explicitly identifies open PR #153 as the committed enforcement follow-up: its frozen-baseline test prevents newly introduced untyped MENU blocks, while the default-flip change is required to add declaration-driven runtime enforcement and bind or retire existing autonomous paths.; verifier:codex-sdk=FINDING -- The ADR explicitly says no Studio code currently reads a declared type and that both existing autonomous paths still resolve undeclared gates by runtime judgement; the cited open PR #153 only validates present TYPE literals and freezes new untyped menus, not the blocking fallback at runtime.

Rewritten, in identical terms to the sibling finding on the lint PR so the two cannot be read as improvising.
My previous answer was wrong rather than incomplete. I had argued the contract was "not yet violable" because nothing consumes a declared type — the first half is true, the conclusion is not. Two shipped paths already resolve undeclared gates by runtime judgement: skills/studio/modules/gates/simple-mode-rules.md:19 (assistant mode's own auto-selection rule, no overlay involved) and workflows/brave-new-world.md.
Three consequences. The ADR states that plainly. The retirement obligation now covers assistant mode's rule as well as the overlay — the mode table marks assistant "unchanged", which is true of its narration and false of its auto-selection. And this removed a self-contradiction: the compatibility-boundary paragraph already said the overlay resolves undeclared gates, so both statements could not have been true.
The outstanding work is enumerated on #128, including the test that an omitted type produces blocking behaviour.

Re-verified against the current code (f51ea05) and this is still an issue. reviewer:claude-sdk=PASS -- The ADR itself explicitly states there is no enforcement yet: 'Nothing in Studio reads a declared type today', 'a lint over source cannot' bind the two undeclared-resolution paths, and enforcement 'belongs with the change that introduces declaration-driven resolution.' It names the only tracked mechanism as PR #153's test_the_untyped_menu_surface_does_not_grow, which freezes existing untyped gates in a baseline and fails on new ones, and clarifies the lint only checks that a present TYPE is one of three literals — it does not enforce that undeclared defaults to blocking. The ADR is honest that this is a documentation-level decision with an explicit named follow-up (#152/#153) rather than a hidden gap, so the check holds as PASS: the ADR does not overclaim mechanical enforcement, it discloses the gap and points to a concrete tracked follow-up.; reviewer:codex-sdk=FINDING -- The ADR explicitly states that nothing currently reads a declared type and that undeclared gates are still auto-resolved by existing assistant/overlay paths; the cited open PR #153 only freezes newly added untyped menus and validates present literals, not runtime fail-closed behavior.; verifier:codex-sdk=FINDING -- The ADR explicitly admits that no Studio code currently reads a declared type and that assistant mode and the autonomy overlay still autonomously resolve undeclared gates; the cited open PR #153 only freezes growth of the untyped surface and validates present TYPE literals, not fail-closed runtime behavior.
There was a problem hiding this comment.
No argument with the finding, and nothing in this PR closes it. What has changed
is that the record now says which change does, and how it will be checked.
The disclosure is also stronger than when you first raised it: there are three
shipped paths that resolve undeclared gates by runtime judgement, not two —
assistant mode's auto-selection rule, the overlay, and sub-agent dispatch's
approve-once pre-set at skills/studio/modules/subagents/dispatch.md:43, whose
EMIT_MENU/WAIT/STOP_TURN guards it suppresses. All three must be retired or
bound to declared types by the change that first consumes declarations.
A new section, What closes each open gap, gives this row: closed by the change
that first consumes declarations once its prerequisites are met; proven by a
MENU with no TYPE stopping for fresh authorisation, in core and kit paths,
with those three paths retired or bound. That is your own How to verify, moved
into the record so a reviewer of that change can check it off.
I do not expect this thread to close on re-verification, and I am not asking it
to. The objection is that no code reads a declaration, which stays true until
that change lands. It is recorded as an open gap with a named owner-change rather
than argued.

Default-move prerequisites omit required decision-log work
Severity: Major
Problem
The ADR says exactly three things must exist before the default moves, but later identifies an unnamed chat-gate-to-record path, logging opt-out behavior, and a core-version field as untracked obligations. At least the recording path and core-version field are required by the earlier mandatory logging contract, so the obligation set is not exhaustively reconciled.
How to reproduce
- Read the three-item prerequisite list. 2. Read the mandatory autonomous-resolution recording requirements. 3. Compare them with the later list of three untracked logging obligations.
Expected behavior
All implementation obligations required before enabling the autonomous default are either included in the prerequisite list or explicitly classified as deferred and non-blocking.
Actual behavior
Required logging implementation work is named only as untracked negative-consequence work, not reconciled with the default-move prerequisites.
default moves
-> autonomous resolution
-> mandatory record
-> chat-gate-to-record path + core version
^ omitted from prerequisite list
Impact
Implementers can treat the three listed prerequisites as complete and enable the default while lacking the required audit trail.
Suggested correction
Reconcile the lists: add the necessary logging obligations to the pre-default prerequisites, or explicitly state why each is not required before the default changes.
How to verify
Confirm every mandatory recording requirement has an owner/status and appears in, or is explicitly excluded from, the pre-default prerequisite set.
There was a problem hiding this comment.
Correct, and it was a modelling error rather than loose wording. If recording is
mandatory and no write path exists, then the default cannot move without it.
The write path is now the fourth prerequisite, and the record says an earlier
draft filed it as a consequence. The remaining two logging obligations — the
opt-out policy and a core-version field the envelope has no slot for — stay
recorded as untracked, because neither blocks the flip: an opted-out session and
a missing version field degrade the audit trail rather than permit an
unauthorised resolution.

Re-verified against the current code (6239e0f) and this is still an issue. reviewer:claude-sdk=FINDING -- The three enumerations of obligations (the 4-item prerequisite list, the 5-row 'what closes each gap' table, and the 9-row Confirmation table) do not name a single consistent set; several items appear in one list and are silently absent from the others.; reviewer:codex-sdk=FINDING -- The default-move list has four prerequisites, but the Negative consequences section introduces two additional untracked decision-log obligations (logging opt-out and a core-version envelope field) without stating whether they block the default; the Confirmation table likewise omits them.; verifier:codex-sdk=FINDING -- The ADR’s prerequisite accounting diverges: it declares four prerequisites, but later describes the logging write path as the fourth of three decision-log obligations while leaving the other two untracked, and the Confirmation table does not consistently carry those obligations as completion checks.
There was a problem hiding this comment.
All three reviewers agreed on this one and they were right. It was my error, introduced when I promoted the write path to a prerequisite.
Two things were wrong. "The write path is now the fourth prerequisite" sat beside "three decision-log obligations", which reads as fourth of three. And the three enumerations had no stated relationship, so an item could appear in one and vanish from another without contradiction.
The relationship is now stated, and true: the gap register is complete; the prerequisite list is the subset of it that must close before the default moves; the Confirmation table is how acceptance is checked, not a duplicate register. Every register row either carries a prerequisite number or says it does not block the flip — the single exception is the fail-closed row, which the flip resolves rather than being blocked by. It audits as 9 rows = 4 prerequisite + 4 non-blocking + 1.
On your specific question — whether the two remaining logging obligations block the default: they do not, and the rows now say so with the reason. An opted-out session and a missing core-version field both degrade the audit trail; neither permits a resolution the declaration did not already authorise, which is what a prerequisite has to prevent. The write path is different: without it, flipping the default produces resolutions that are mandated to be recorded and are not. That is why it, and only it, became prerequisite 4.
Prerequisites 1 and 2 also gained register rows while I was checking this. They had none, which would have made the subset claim false the moment anyone tested it.

Re-verified against the current code (3c4a9b9) and this is still an issue. reviewer:claude-sdk=PASS -- Cross-checking the three enumerations shows they align by explicit cross-reference rather than diverging: the four numbered prerequisites (trigger set/unit, law amendments, approved keyed source, write path) are each referenced by number in the 'What closes each open gap' table rows (prerequisite 1/2/3/4 respectively), and the Negative-consequences bullets explicitly restate only the non-blocking items (untyped inventory, logging opt-out, core-version field) while naming the write path as 'prerequisite 4' consistently. The gap table itself states its own rule ('every row either carries a prerequisite number... or says it does not block the flip — except the first fail-closed row') and that one exception (undeclared-gate fail-closed behavior) is explicitly called out as resolved by the flip itself rather than silently omitted. The Confirmation table is explicitly disclaimed as a different, non-duplicate register ('how acceptance is checked, not a duplicate of this register'), so its differing criteria count (9) is not a contradiction but a stated distinction. No item is silently dropped, renamed, or contradicted across the three passes.; reviewer:codex-sdk=FINDING -- The four prerequisites are internally reconciled with the open-gap register, but the Confirmation table omits prerequisite 4 (the mandatory chat-gate-to-record() write path) and does not independently check prerequisite 2's runtime-law amendments, so it is not a complete, consistent acceptance enumeration.; verifier:codex-sdk=FINDING -- The enumerations conflict: prerequisite 4 requires a write path that records the core version for every autonomous resolution, while the gap register and Negative consequences classify the absence of a core-version envelope field as non-blocking for the default flip.

Studio turns routine workflow mechanics into chat gates, and the mode gate suggests `normal` — which `simple-mode-normal.md` defines as a no-op that continues with every existing menu, gate and stop, so it adds stops without adding help. An autonomous-by-default overlay already exists but is opt-in and re-derives risk per menu at runtime rather than reading a declaration. Nothing in ADR-0001..0022 covers interaction modes, so both the default and any risk model would be introduced with no recorded basis. Record the decision: - four modes, with `guided` distinct from `assistant` so the current `normal` behaviour survives under a name rather than being removed; the active mode is announced rather than asked — the announcement MUST precede the first autonomous resolution — and mode is session state that does not persist across sessions, so a session cannot silently start more autonomous than the default - each gate declares a risk type as a static constant of its MENU block — `confirmation`, `decision`, `blocking` — and an undeclared gate is treated as `blocking`, so no installed kit or legacy path changes behaviour until its author declares a type - a `decision` gate may resolve autonomously only from an approved, structured, explicitly keyed source using exact-match semantics: no inference from prose, no similarity matching, no normalization at lookup time, and no cached resolution state that is no longer valid for the current inputs - a `blocking` gate is passable only by a fresh explicit user authorisation satisfying that gate; auto-proceed and proceed-after-approval are distinct - autonomous mode does not grant authority; it selects how already-declared authority is exercised Bounds ADR-0018 rather than superseding it: delegated unattended execution remains valid, and this ADR governs interactive-session autonomy. Four things must exist before the default moves, not three: the write path from a chat gate to `record()` is a prerequisite rather than a negative consequence, because recording every permitted autonomous resolution is mandatory and no such path exists — flipping the default without it would produce exactly the unrecorded resolutions the second invariant forbids. The third prerequisite now states what its contract must define, because approval alone is not sufficient: source identity, provenance, and binding to the current inputs. The resolution invariant already forbids resolving from cached state that is no longer valid for the current inputs, which is the freshness half of the third; the other two have no home until that source exists. A mode-by-declared-type matrix covers every combination rather than specifying the autonomous default alone: only that default resolves a gate from its declared type, and every other mode asks whatever the type says. `debug` adds breakpoint pauses to `guided` behaviour rather than replacing it, which is what "unchanged by this decision" means. The three enumerations now have one stated relationship. The gap register is complete; the prerequisite list is the subset of it that must close before the default moves; the Confirmation table is how acceptance is checked rather than a duplicate register. Every row of the register carries a prerequisite number or says it does not block the flip, except the fail-closed row that the flip itself resolves. The two remaining decision-log obligations are marked non-blocking with the reason: an opted-out session and a missing core-version field degrade the audit trail without permitting a resolution the declaration did not authorise. Each remaining gap names the change that closes it and the check that proves it, so a deferral is reviewable rather than argued. The declaration's grammar is referenced rather than restated — `architecture/specs/PDSL.md` fixes the syntax, this record fixes the model. Mode's lifetime is PDSL's existing `scope session`, and this record deliberately does not define that boundary: the term is used by 48 declared variables across nine modules, so fixing it here would redefine all of them rather than only mode. Scoped to the decision and the obligations it creates. Per-site counts and measured stop counts are deliberately excluded — they go stale and are not what is being decided; the reachability walk and the migration inventory are tracked on the requirement, and the PDSL rule wording on its own issue. Numeric acceptance thresholds are excluded for the same reason — those are evaluation policy, not architectural decisions. `cfs validate` PASS (0 errors, 0 warnings); `make test` 5282 passed; `make pylint`, `make vulture-ci` clean; `make spec-coverage` all thresholds met (granularity 0.4614); `make test-coverage` clean.

Required mode-trigger set is left wholly unspecified
Severity: Minor
Problem
The prerequisite demands a closed trigger set disjoint from existing overlay activation phrases, but contains no proposed members for the set to be implemented or reviewed.
How to reproduce
- Read prerequisite 1 under What must exist before the default moves. 2. Compare its described required set with the listed existing overlay phrases. 3. The ADR provides no new trigger list.
Expected behavior
The ADR should provide a candidate normative trigger set or reference a draft artifact containing it.
Actual behavior
Only ownership and disjointness requirements are stated.
existing overlay phrases ──┐
├─ must be disjoint
new trigger set: unspecified ┘
Impact
Disjointness cannot be evaluated from the ADR and implementers receive no bounded starting contract.
Suggested correction
List the intended trigger tokens/phrases or reference the authoritative proposed trigger-set artifact.
How to verify
Check that every proposed mode trigger is enumerated and does not overlap overlay activation.

Dispatch approval can bypass the named gate
Severity: Major
Problem
The ADR describes the named dispatch gates as blocking until typed, while the current dispatch rules permit a calling workflow to set SUB_AGENT_GROUP_DECISION to approve-once based on an explicit imperative. This makes the approval gate's menu, WAIT, and STOP_TURN conditions false.
How to reproduce
- Start a dispatch group with both dispatch mode and group decision unset. 2. Send an explicit imperative naming a target operation. 3. Let the caller set approve-once. 4. Run SubAgentDispatchApprovalGate and observe that native dispatch can proceed without emitting the approval menu.
Expected behavior
A blocking dispatch gate requires fresh explicit authorization through its gate.
Actual behavior
The inferred approve-once state bypasses the gate interaction and permits native dispatch.
explicit imperative
-> approve-once pre-set
-> approval menu skipped
-> native dispatch
Impact
The claimed authorization boundary is not currently enforced for the dispatch path.
Suggested correction
Retire or bind the pre-set approve-once path before treating undeclared dispatch gates as blocking.
How to verify
Test that an unset/undeclared dispatch gate always stops for fresh authorization, including explicit-imperative requests.

What
Records the decision that Studio's interaction default becomes autonomous, and the gate-risk model that makes that safe. Documentation only — one new ADR plus its registration in
DESIGN.md. No engine change.Why now
Two things make the current shape worse than it needs to be:
normal— is a documented no-op:simple-mode-normal.mdinstructs the runtime to continue with the workflow's existing menus, gates, stops. Normal is therefore the most question-heavy mode available.Nothing in ADR-0001 through ADR-0022 covers interaction modes, so both the default and any risk model would otherwise be introduced with no recorded basis.
What the ADR records
guidedis distinct fromassistant, so the currentnormalbehaviour survives under a name rather than being removed. The active mode is announced, not asked, and is session state — a cancel or an off-protocol reply does not reset it.confirmation/decision/blockingas a static constant of itsMENUblock, never computed at runtime. An undeclared gate is treated asblocking, so core gains the capability without changing the behaviour of any installed kit or legacy path until its author declares a type.decisiongate may resolve autonomously only from a structured, explicitly keyed source using exact-match semantics — no inference from prose, no similarity matching, no normalization at lookup time, and no cached resolution state no longer valid for the current inputs. This is what makes autonomous resolution deterministic and therefore reviewable.blockinggate is passable only by a fresh explicit user authorisation satisfying that gate; auto-proceed and proceed after explicit approval are distinct. Validators, prerequisite checks and closing audits run identically in every mode — autonomy changes who answers the questions, never what gets checked.Numeric acceptance thresholds are deliberately excluded: those are evaluation policy, not architectural decisions, and an ADR carrying a number goes stale.

The decision model was reviewed twice before this was written, and both passes changed it. Worth knowing for anyone reading the invariants:
