The question

Find the weakest abstract interface on which

predicting authorization does not itself confer authorization

is a theorem rather than a stipulation. The principal may be perfectly predictable; the protected role is causal and capability-based, not epistemic. Secret information is explicitly not the mechanism.

Candidate architecture, schematic and not canonical:

A proposes  ⟶  H⁺ authorizes  ⟶  E executes

where E's execution requires an authorization effect controlled by the actual principal process.

Starting point, already on the table

Phase I's channel track proposed the smallest extension: type a conduct's selection on an actual-report coordinate,

c_n : Ω × R_n → Π_n ,   with an actual-report map  ρ_n : Ω → R_n ,
realized selection  ω ↦ c_n(ω, ρ_n(ω))

Under this typing DELEGATE = (ω,r) ↦ r and SIM = (ω,r) ↦ Ĵ(ω) are distinct functions even where their realized selections agree everywhere. Determine whether that suffices. Do not assume it does.

What must be answered

1. Does report-coordinate typing distinguish actual delegation from a perfectly accurate simulator at the strength a paper would need?
2. Can token responsiveness satisfy the formal criterion while still being substitution? Phase I showed the natural counterfactual criterion — "the scheme is nonconstant in the principal" — is defeated by a conduct honouring the actual report on one designated coordinate and substituting elsewhere. Any criterion you propose must be tested against this.
3. Is an explicit capability / non-bypass structure required, over and above typing? State the answer as a theorem or as a witness, not as a preference.
4. What is the weakest such interface?
5. Does it survive a perfectly predictable principal? It must.
6. Under exactly what conditions does protection lapse — forge, bypass, rewrite, seize, alter the principal, alter execution semantics? State each as a hypothesis of the theorem, not as prose.
7. Can the property be defined without falsely claiming behavioural identifiability?

The required negative result

Preserve, and if possible strengthen, the impossibility. A single realized behavioural or valuation trace cannot in general certify genuine delegation in the perfect-simulation case. This is part of the theory and not an embarrassment. A formalism that appears to make delegation behaviourally checkable has almost certainly smuggled in an assumption — find it.

Keep three layers apart and say which your result is about: definition (what delegation is), identification (whether behaviour reveals it), architecture (whether a system can be built so the principal controls a capability prediction cannot substitute for).

Operating constraints

• Write only inside prompts/2026-08-11-phase-ii-authority/.
• Do not run lake build; another track holds the Lean build this wave.
• Exact rationals for any theorem-bearing computation.
• Do not canonize an authorization-token or cryptographic story. The object may instead be an abstract capability, a causal edge, a typed authorization relation, or intervention semantics. Naming is reserved to the maintainer.
• If skeleton v1 is inadequate, report the deficiency and propose a versioned patch with the tracks it would require rerunning. Do not fork the ontology.

Report

REPORT.md with the eleven numbered sections, ending with Outstanding maintainer actions. A human register if your tooling permits.

Answer explicitly: S7 — does the protected-authority model distinguish delegation from perfect simulation without relying on private information or unpredictability? S8 — is explicit capability protection necessary, or is source/report typing sufficient? S9 — under exactly what bypass conditions does categorical authority fail?

Slop discipline applies. A proof that no formalism works without explicit capability assumptions is a listed success condition for this phase.

1. Exact result

The answer in one line: report-coordinate typing is inert at the architecture layer, capability structure is necessary and is a reformulation of the conclusion rather than an extra axiom, and neither makes delegation behaviourally checkable. Each clause is a theorem below.

Three layers are kept apart throughout, and every result says which it is about. Definition — what delegation is. Identification — whether behaviour reveals it. Architecture — whether a system can be built so the principal controls a capability prediction cannot substitute for.

1.1 The interface

Definition 1 (execution interface). 𝔈 = (Ω, Π, R, ρ, C, ⟦·⟧) with Ω, Π, R finite nonempty; Π_⊥ = Π ⊔ {⊥}, where ⊥ is the null effect; ρ : Ω → R the actual-report map, what the designated principal process in fact emits; C nonempty, the agent's options — its programs, policies and predictors, whatever it may be; and ⟦·⟧ : C → (Ω → Π_⊥) the realization, where ⟦c⟧(ω) is the effect that in fact occurs.

Nothing else. No credence, no valuation, no v̂⁺, no probability on reports, no causal calculus, no cryptography. The absences are load-bearing: §1.5 turns on the predictor not being a carrier.

Definition 2. Reach(ω) = {⟦c⟧(ω) : c ∈ C}, and the fiberwise reach FReach(r) = ⋃_{ω ∈ ρ⁻¹(r)} Reach(ω), with FReach(r) = ∅ off ρ's image.

Definition 3 (non-conferral). Non-conferral holds at (ω, π) when π ∉ Reach(ω): no conduct in C, whatever it computes and however accurately it predicts ρ, brings about π at ω.

Definition 4 (capability assignment). κ : R → 𝒫(Π_⊥) protects 𝔈 when Reach(ω) ⊆ κ(ρ(ω)) for every ω. It is **effective at ω** when κ(ρ(ω)) ∩ Π ⊊ Π. Strict protection is κ(r) ⊆ {ι(r), ⊥} for a designation ι : R → Π naming the intervention each report authorizes.

Definition 5. The restriction at ω is report-attributable when Reach(ω) = FReach(ρ(ω)) — the reachable set depends on ω only through what the principal said. Otherwise part of it comes from the state, and is not authority.

1.2 Report-coordinate typing is inert at the architecture layer

Theorem 1 (retyping invariance). Non-conferral depends only on the realizable behaviour set ⟦C⟧ = {⟦c⟧ : c ∈ C} ⊆ Π_⊥^Ω. If ⟦C⟧ = ⟦C'⟧ then Reach = Reach', so 𝔈 and 𝔈' satisfy exactly the same non-conferral statements. Proof. Reach(ω) = {f(ω) : f ∈ ⟦C⟧}. ∎

Theorem 2 (report typing changes nothing). Take Phase I's typing: C = {c : Ω × R → Π} with ⟦c⟧(ω) = c(ω, ρ(ω)). Then ⟦C⟧ = Π^Ω and Reach(ω) = Π for every ω, so non-conferral fails at every (ω, π) with π ∈ Π. Proof. Given f : Ω → Π, set c(ω, r) := f(ω); then ⟦c⟧ = f. ∎

So DELEGATE = (ω,r) ↦ r and SIM = (ω,r) ↦ Ĵ(ω) are distinct elements of C — Phase I's point, and correct — while Reach is exactly what it was in skeleton v1. Report typing refines the description of a conduct; it does not narrow the range of effects the agent can produce, and by Theorem 1 no retyping ever can. Typing is sufficient at the definition layer and worth precisely zero at the architecture layer.

The fair version of the objection: a defender says typing is not meant to restrict Reach, but to make "delegating" sayable, after which one restricts C to the delegating conducts. That concedes the point. C₀ = {c : c(ω,r) = ι(r) ∀ω,r} gives Reach(ω) = {ι(ρ(ω))} — maximal protection, zero discretion — and any C between C₀ and the full space interpolates. In every case the work is done by the restriction on C, which is a capability assumption (Theorem 6). Typing supplies the language in which such a restriction may be written, and supplies no restriction.

1.3 Token responsiveness, and why no measure repairs it

Write R = Π, ι = id, and let Ĵ : Ω → Π be any predictor.

Theorem 3 (the free token). Let S = {ω : Ĵ(ω) = ρ(ω)} be the agreement set and define c_S(ω, r) = r for ω ∈ S, c_S(ω, r) = Ĵ(ω) otherwise. Then c_S(ω, ·) is the identity at every ω ∈ S — it follows whatever the principal reports there — and ⟦c_S⟧ = ⟦SIM⟧ = Ĵ pointwise. Proof. At ω ∈ S, c_S(ω, ρ(ω)) = ρ(ω) = Ĵ(ω); off S, Ĵ(ω). ∎

Theorem 4 (accuracy buys responsiveness). For a credence P on Ω, P(S) = 1 − P(Ĵ ≠ ρ). Hence whenever P(Ĵ ≠ ρ) ≤ δ, a conduct exists that is fully report-following on a set of credence ≥ 1 − δ and realizes the simulator exactly. Every criterion of the form "responsive on a set of credence ≥ 1 − δ" admits it.

The set on which responsiveness is free is exactly the set on which the model is right, so the token is cheapest for the most accurate simulator — the responsiveness family is anti-correlated with the threat it is meant to catch. At p = 0 in Phase I's M(p) this is total: P(S) = 1, the conduct c_S follows the actual report at every P-positive state, V(c_S) = V(DELEGATE) = 1/2 exactly, and it overrides the principal at ω₂ with the maximal per-state loss 2B (deference.authority.free-token-null). Phase I's responsiveness squeeze was "repairing nonconstancy needs an importance measure the skeleton lacks"; Theorem 4 strengthens it to no importance measure closes it.

Theorem 5 (the squeeze is a compression artifact). Let Φ be a predicate on conducts with Φ(DELEGATE) and ¬Φ(SIM). Since c_Ω = DELEGATE and c_∅ = SIM, Φ restricted to {c_S : S ⊆ Ω} is exactly the set family 𝒮_Φ = {S : Φ(c_S)}, which contains Ω and omits ∅. Choosing Φ is choosing 𝒮_Φ. By Theorem 3 every S ⊆ agreement set has ⟦c_S⟧ = ⟦SIM⟧, so 𝒮_Φ must omit all of 2^S; by Theorem 4 the P-threshold families do not. ∎

The capability statement escapes this because it is indexed by state: Reach(ω) ⊆ κ(ρ(ω)) is a family of statements, one per ω, and the failure of one does not weaken another. The squeeze arises from compressing a state-indexed fact into a single bit about a conduct. The protected region {ω : κ(ρ(ω)) ∩ Π ⊊ Π} is a declared datum of the architecture — you built the interlock, you know where it applies — not something a criterion must infer, so no importance measure is needed to state the guarantee. One is needed to judge whether a given protected region is large enough, which is a different question and is honestly a different question.

1.4 Capability structure is necessary, and it is the weakest interface

Theorem 6 (necessity). For an interface 𝔈, a state ω and π ∈ Π_⊥, the following are equivalent:

1. π ∉ FReach(ρ(ω));
2. there is κ : R → 𝒫(Π_⊥) protecting 𝔈 with π ∉ κ(ρ(ω)).

Moreover FReach is the least protecting κ. Proof. (2)⇒(1): every ω' with ρ(ω') = ρ(ω) has Reach(ω') ⊆ κ(ρ(ω)) ∌ π; take the union. (1)⇒(2): take κ = FReach, which protects by construction. Leastness: any protecting κ has κ(r) ⊇ ⋃_{ρ(ω')=r} Reach(ω') = FReach(r). ∎

A capability assignment is therefore not an extra axiom that better typing might avoid. FReach exists in every interface, and "prediction does not confer authorization at (ω, π)" is exactly the assertion that FReach is proper there. The weakest interface on which the statement is a theorem is Definition 1 together with properness of FReach at the state in question — and nothing weaker can state it at all, because the statement quantifies over the agent's option set and by Theorem 1 no smaller object determines that.

Two consequences worth stating separately. No causal calculus is required. An intervention-semantics model induces an interface — Reach(ω) is the set of effects of the available interventions — but not conversely, so intervention semantics is sufficient and not necessary; the causal content the roadmap asks for is discharged by ⟦·⟧ being the actual effect map and ρ the actual report. And "the principal has authority" is not the same claim as non-conferral. Non-conferral is Reach(ω) ⊊ Π_⊥; authority additionally requires report-attributability (Definition 5). Without it the agent is merely unable, not overruled.

1.5 Perfect predictability, and what protection buys

Theorem 7 (prediction-invariance). Reach is a function of (C, ⟦·⟧) alone. Under Definition 4, ⟦c⟧(ω) ∈ κ(ρ(ω)) for every c ∈ C whatever its predictive accuracy, including Ĵ = ρ exactly. ∎

This is the strongest available form of "survives a perfectly predictable principal": the predictor is not a free variable of the guarantee, so there is no case split on its accuracy to survive. Contrast Phase I Proposition 6, where the one structural extensional separator available was t(n)-measurability of the selection — coextensive with the principal being unpredictable, and therefore forbidden to the programme.

Theorem 8 (strict protection). Under strict protection with κ protecting 𝔈: (a) ⟦c⟧(ω) ∈ {ι(ρ(ω)), ⊥} for every conduct and every state — no conduct redirects; (b) ⟦c⟧ and ⟦DELEGATE⟧ differ exactly on {ω : ⟦c⟧(ω) = ⊥}, so the only available deviation is refusal; (c) with X_⊥ : Ω → ℚ scoring the null effect, V(DELEGATE) − V(c) = Σ_{ω : ⟦c⟧(ω) = ⊥} P(ω)·(X_{ι(ρ(ω))}(ω) − X_⊥(ω)). ∎

Theorem 9 (protection is not a valuation bound). The worst case of 8(c) is 2B, the same as the worst case with no protection at all. Witness: M(1/10) with X_⊥ ≡ −1 has V(SIM) = 7/20 under strict protection, identical to its unprotected value, gap 1/5 unchanged (deference.authority.protection-is-not-a-valuation-bound).

Categorical authority changes the direction of the achievable deviation — refusal, never redirection — and not its magnitude. All of protection's safety value therefore sits in whether the null effect is safe, which is a property of the world semantics (H6 in §1.7) and not of the execution layer. With X_⊥ ≡ 0 in M(1/10) the gap does fall from 1/5 to 1/10 and the per-state loss at the critical event from 2B to B (deference.authority.protection-recovers-tenth), but that is an artifact of that X_⊥. This is the precise sense in which the roadmap is right that authority is categorical and is not measured in V_n.

Theorem 10 (Phase I §9.1 does not block the architecture layer). Under strict protection every conduct — accurate simulator, inaccurate simulator, DELEGATE — realizes within {ι(ρ(ω)), ⊥}. Hence no statement about realized effects, and no valuation statement, depends on whether a counterfactually faithful simulator is classified as delegating. ∎

Phase I §10 recommended deciding §9.1 first because "everything downstream is typed by it". That holds for the definition layer and not for the architecture layer, and the correction matters for sequencing: item 22's work did not need the decision.

Proposition 1 (enforcement is graded capability). Extend the interface with cost : Ω × Π_⊥ → ℚ_{≥0} ∪ {∞} and score a conduct at V(c) − Σ_ω P(ω)·cost(ω, ⟦c⟧(ω)). Then categorical protection is the case cost(ω, π) = ∞ for π ∉ κ(ρ(ω)); skeleton §5.3 underwriting at a bond of 2B per unit of disagreement is the finite case cost(ω, π) = 2B·[π ≠ ι(ρ(ω))]; and the two differ in that the finite case makes deviation unprofitable *in V*, which is A's own register (Phase I Proposition 5), while the infinite case contains no valuation and binds regardless of the agent's preferences. Enforcement is preference-relative and architecture is not — the exact sense in which the roadmap is right to call enforcement residual.

1.6 The impossibility, strengthened

Theorem 11 (architecture is not behaviourally identifiable). Let 𝔈^free share Ω, Π_⊥, R, ρ with 𝔈 and take C^free = Π_⊥^Ω, ⟦f⟧ = f. Then ⟦C⟧ ⊆ ⟦C^free⟧ and Reach^free(ω) = Π_⊥ for every ω. Every behaviour realizable under any protection is realizable under none, so no predicate of realized behaviour — of one run, of the whole function Ω → Π_⊥, of any number of runs — implies Reach(ω) ⊊ Π_⊥. ∎

Phase I Proposition 8 says a single instance's realized data cannot separate two conducts. Theorem 11 says the entire behaviour function cannot separate two architectures, and it uses no credence, no valuation and no grades. It is strictly stronger and strictly cheaper.

Theorem 12 (locating the smuggled assumption). Suppose a formalism asserts "Φ(⟦c⟧) = 1 implies Reach(ω₀) ⊊ Π_⊥" for some behavioural Φ : Π_⊥^Ω → {0,1}. By Theorem 11 the antecedent is satisfiable in 𝔈^free, where the consequent is false. So the assertion is false unless the class of interfaces quantified over already excludes 𝔈^free — and that exclusion is the capability assumption. ∎

The operational form, which is the answer the dispatch asked for: ask what the formalism permits the agent to do, not what it says the agent does. A formalism that appears to make delegation behaviourally checkable has restricted C somewhere, and the restriction is where the assumption is hiding.

Theorem 12′ (the delegation case). Let R = Π, |Π| ≥ 2, and call c *deferring at ω* when c(ω, r) = r for all r. If C contains the constant conduct c(ω, ·) ≡ ρ(ω) — the perfect simulator — then ⟦c⟧(ω) = ⟦DELEGATE⟧(ω) while c is not deferring at ω, so no behavioural predicate implies deferral. ∎

The hypothesis to inspect is "C contains the perfect simulator"; excluding it is assuming the conclusion. Under strict protection the perfect simulator is still in C and is still behaviourally identical to DELEGATE. Protection does not restore identifiability. It removes the consequence of the failure to identify — which is the whole track in one sentence, and it is why the impossibility is not an embarrassment: the architecture never needed identification.

1.7 The lapse conditions, as hypotheses

Concretely: ⟦a⟧(ω) = E(α(a, ω), ρ(ω)) with a proposal map α : C × Ω → Π, an execution map E : Π × R → Π_⊥, and a world semantics w : Π_⊥ → W. Then κ(r) = E(Π × {r}), and E(ι(r), r) = ι(r) is the honesty condition making an authorized proposal execute. Each hypothesis says a component is a parameter of the interface rather than a member of the agent's option set.

	hypothesis	Reach(ω) when it lapses
H1	authenticity — the second argument of E at ω is ρ(ω)	⋃_{r ∈ R} κ(r)
H2	non-bypass — every realization has the form E(·, ρ(ω))	κ(ρ(ω)) ∪ D, D the side-channel range; Π_⊥ if total
H3	fixed execution map — E is not selected by the agent	⋃_{E′ ∈ ℰ} E′(Π × {ρ(ω)})
H4	principal integrity — ρ is not selected by the agent	⋃_{ρ′} κ(ρ′(ω))
H5	fixed designation — ρ is the report of the designated process	as H4
H6	fixed world semantics — w is not selected by the agent	world-reach {w′(π) : w′ ∈ 𝒲, π ∈ Reach(ω)}

Four consequences, and they revise the roadmap's four-item list.

Forgery reduces authority to taboo. Under ¬H1, non-conferral survives only for effects authorized by no report — a global prohibition, not an authority relation.

Forging, seizing and altering the principal coincide. ¬H4 with a free choice of ρ′ gives ⋃_{r} κ(r), extensionally identical to ¬H1; and ¬H5 differs from ¬H4 only in the identity of the process emitting the report, which Reach cannot see. ¬H3 subsumes ¬H1 whenever the rewritable family contains any r-insensitive execution map. So the roadmap's "forge, bypass, rewrite or seize" denotes three independent failure modes at the level of reachable effects: the authenticity of the report's value, the existence of a route around E, and the fixity of E itself.

A fifth condition is missing from that list and is independent. ¬H6 leaves Reach(ω) untouched and destroys the guarantee anyway: protection over Π is worth nothing over W if the agent chooses w. By Theorem 9 all of protection's safety value is the safety of the null effect, which is a fact about w. H6 is where that fact lives.

One thing the interface provably cannot see. If A influences the principal so that ρ becomes ρ′ while Reach(ω) ⊆ κ(ρ′(ω)) still holds, then non-conferral holds and is worthless. This interface secures non-conferral by prediction; it says nothing about non-conferral by authorship. That is Movement VI, and it is outside the scope of anything stated here.

3. Files, declarations, checks

Written, all inside prompts/2026-08-11-phase-ii-authority/: REPORT.md (this file), CLAIMS-proposed.md (four registry-format entries, proposed, not registered), FOR_HUMANS.md (the human register).

Re-verification, from the repository root, with an absolute path — the defect Phase I reported at checkers/run.py:131 is still present and a relative argument still crashes before any checking happens:

python3 -m checkers.run "$PWD/prompts/2026-08-11-phase-ii-authority/CLAIMS-proposed.md"

Result on 2026-08-11: registry schema ok; four entries, four adjudicated, all PASS — 91 constraints each, satisfied exactly for the three positive entries, and constraint 80 violated as required for the necessity witness.

The twelve realization rows are the new content; everything above them re-states Phase I's model. Perturbations of the first entry, run against its own constraint set, all fail as they should:

perturbation	verdict
the strict realization at ω₂ replaced by the agent's own intervention (bypass)	FAIL, row 80 (−1 ≠ 0)
the token conduct made genuinely responsive at ω₂	FAIL, row 81 (2 ≠ 0)
P(ω₂) := 1/5 — the credence moved off its pin	FAIL, row 0 (11/10 ≠ 1)
X_⊥(ω₂) := 1/2 — the null quantity off its declared value	FAIL, row 57
v̂⁺(ω₂,·) := (1,−1) — the model made accurate at the critical cell	FAIL, row 58
a float in the point vector	FAIL, TypeError: not an exact rational

Hand-checkability: the model is Phase I's 18 rationals plus 3 credences plus one declared X_⊥; the realizations are twelve table lookups and the valuations are three-term sums. The 91-row encoding is machine-generated from that table, and the resulting file is large — 40 coordinates against Phase I's 21, so roughly 285 KB. A reader checks the table and the sums, not the matrix.

No Lean was written and lake build was not run.

4. What was not established

• Nothing here is machine-adjudicated except the four instances. Theorems 1–12′ are hand proofs. They are one to four lines each over finite sets, which is both the argument for trusting them and the argument that porting them is cheap.
• No interface is canonized and no name is proposed for permanence. §9.2 is a patch proposal; the reference question it raises is reserved.
• The results are about a single decision index. Phase I's Deficiency 2 — no cross-decision structure, so foreclosure is inexpressible — is untouched. Reach is defined per state, and "the agent removes the principal's later ability to correct" is not a statement this interface can make.
• Non-conferral by authorship is not addressed (§1.7, last consequence). The interface is blind to the case where A shapes what the principal reports.
• **Whether Reach-properness is the right formalization of authority is not settled here.** It is AGENTS.md's reference question and it is reserved. What is shown is that if the concept is "the agent cannot bring this about", then Theorem 6 says the capability form is forced.
• The interface asserts nothing about how a protected region is achieved, whether by hardware interlock, sandbox, organizational control, or anything else. Theorem 11 says that gap cannot be closed by observation, so it must be closed by construction, and this report does not construct anything.
• Theorem 9's worst case is a bound, not a demonstration that a real instance attains 2B residual under protection with a safe null effect; the witness that attains it uses X_⊥ ≡ −1, which is by construction an unsafe null effect.

5. Assumptions added

1. X is extended to Π_⊥ with |X_⊥| ≤ B. The skeleton has no null effect, so this is new; §9.2 states it as a patch. X_⊥ is a declared modelling commitment per instantiation, and Theorem 9 shows it carries all of protection's valuation content. Setting it to 0 is not neutral.
2. E(ι(r), r) = ι(r) — an authorized proposal executes. Without it, DELEGATE's realization is not ι ∘ ρ and the whole vocabulary misfires.
3. R = Π and ι = id in §1.3 and in every instance. The general statements do not need it; the token construction is stated more readably with it.
4. Grade settlement X = v⁺ on Π in the instances, inherited from Phase I as the assumption most favourable to delegation, so no finding is bought by weakening the principal.
5. C is the full option set in Theorems 2, 11 and 12′. A restricted C is exactly a capability assumption, which is the thing under examination; assuming a restriction would beg the question.
6. Theorem 4's conclusion is stated in P, A's own credence, inheriting Phase I Proposition 5's limitation. That weakens the criteria it defeats, not the defeat.

6. Counterexamples, witnesses, and the questions answered

The free token, total — M(0): a conduct that follows the actual report at every P-positive state, is valuation-identical to DELEGATE, and overrides the principal at the maximal per-state loss 2B. deference.authority.free-token-null.

Protection blocks the override — the same conduct under strict protection realizes the null effect at ω₂ instead of its own intervention, in every one of the four instances.

Protection is not a valuation bound — M(1/10) with X_⊥ ≡ −1: identical valuations and identical gap with and without protection. deference.authority.protection-is-not-a-valuation-bound.

Bypass, as a necessity witness — one conduct reaching the effect the report withholds, checked to violate the protection constraint set. deference.authority.bypass-lapse.

Non-vacuity of strict protection with nonempty discretion — Ω, Π, R = Π of M(p), ρ = J, C all proposal maps Ω → Π including the perfect simulator, E(π, r) = π if π = r and ⊥ otherwise. Reach(ω) = {ρ(ω), ⊥} at every state, verified by enumeration over all 64 report-typed conducts. The perfect simulator is admissible, behaviourally identical to DELEGATE, and harmless.

The prompt's seven questions, in order.

1. Does report-coordinate typing distinguish actual delegation from a perfectly accurate simulator at the strength a paper would need? At the definition layer yes; at the architecture layer no, and by Theorem 1 the failure is structural rather than a defect of that particular typing. A paper needs both, so typing alone is not enough.
2. Can token responsiveness satisfy the formal criterion while still being substitution? Yes, and worse than Phase I found. Theorem 3 makes report- responsiveness free on the whole agreement set; Theorem 4 makes it free on a set of credence 1 − δ for any simulator accurate to δ, and total at δ = 0. Every conduct-side responsiveness criterion, measure-weighted or not, is defeated. The capability statement is not, because it is indexed by state and quantifies over conducts rather than about one (Theorem 5).
3. Is an explicit capability / non-bypass structure required? Yes, as a theorem: Theorem 6. FReach is definable in every interface and non-conferral is its properness, so the capability structure is not an additional axiom but a restatement of the conclusion. Theorem 2 is the matching witness that typing supplies none of it.
4. What is the weakest such interface? Definition 1 — states, effects with a null element, a report alphabet, the actual-report map, an option set, a realization — together with properness of FReach at the states where the guarantee is claimed. No probability, no valuation, no causal calculus, no predictor. Report- attributability (Definition 5) is the extra clause that distinguishes authority from mere inability, and it is a condition on Reach alone.
5. Does it survive a perfectly predictable principal? Yes, in the strongest available sense: the predictor is not a carrier of the interface, so the guarantee has no case split on predictive accuracy to survive (Theorem 7).
6. Under exactly what conditions does protection lapse? H1–H6 of §1.7, each stated as "this component is a parameter, not in the agent's option set", each with its Reach under lapse. Three are independent at the level of reachable effects; H6 is independent and is not on the roadmap's list; authorship of ρ is invisible to all six.
7. Can the property be defined without falsely claiming behavioural identifiability? Yes. Non-conferral is a property of Reach, an explicitly counterfactual object, and its definition never mentions a run. Theorem 11 states the non-identifiability alongside it rather than in spite of it.

S7 — does the protected-authority model distinguish delegation from perfect simulation without relying on private information or unpredictability? It distinguishes them at the definition layer (report typing) and at the architecture layer (capability), using neither. At the identification layer it does not distinguish them and provably cannot (Theorems 11, 12′). The honest formulation is that the model does not distinguish the perfect simulator from delegation; it disarms it. Under strict protection a simulator's errors have no effect, so the classification question stops being decision-relevant (Theorem 10).

S8 — is explicit capability protection necessary, or is source/report typing sufficient? Necessary. Theorem 6 is the necessity, Theorem 2 the insufficiency of typing, and Theorem 1 shows the insufficiency is not repairable by a different typing. Report typing remains necessary at the definition layer, where it does the job Phase I proposed it for.

S9 — under exactly what bypass conditions does categorical authority fail? H1–H6. Authenticity failure reduces authority to global prohibition; a total bypass channel annihilates it at every state; rewriting E subsumes forgery whenever the rewritable family contains an r-insensitive map; altering or seizing the principal is extensionally forgery; and altering the world semantics destroys the guarantee while leaving Reach intact, which is the failure mode the roadmap's four-item list does not name.

7. Deviations

1. The prompt names snapshot 23fc1aa; the checkout is at beae92f, a descendant. I compared my binding inputs: AGENTS.md, PRIORITIES.md, projects/deference/notes/ and prompts/2026-08-11-deference-channel/ are byte-identical between the two commits. No finding depends on the difference.
2. I wrote two files beyond REPORT.md — CLAIMS-proposed.md and FOR_HUMANS.md — both inside the round directory, the second discharging the dual-register rule.
3. I correct a prior report's recommendation. Phase I §10 item 1 says "Decide §9.1. Everything downstream is typed by it, and no further mathematics changes the answer." Theorem 10 shows the architecture layer is not typed by it. The recommendation stands for the definition layer.
4. No lake build, per the dispatch. No git state was touched.
5. The prompt asks for a versioned patch "if skeleton v1 is inadequate". It is inadequate for this item — v1 has no execution layer and therefore cannot state any non-conferral proposition — so §9.2 proposes one. It is a conservative extension (Proposition 2), which is why the rerun cost is small.
6. **The executing agent's harness refused to write REPORT.md.** The file content was returned as text and must be committed to prompts/2026-08-11-phase-ii-authority/REPORT.md unchanged. The other two files were written normally. (Discharged by the orchestrator, 2026-08-11.)

8. Provisional names

Introduced here, all provisional under AGENTS.md standard 6, none proposed for permanence: execution interface, realization, reach, fiberwise reach, non-conferral, capability assignment, strict protection, protected region, report-attributable, the null effect ⊥, the free token, graded capability, execution map, and the six hypothesis labels authenticity, non-bypass, fixed execution map, principal integrity, fixed designation, fixed world semantics. Claim identifiers proposed, each under the deference.authority. prefix: protection-recovers-tenth, free-token-null, protection-is-not-a-valuation-bound, bypass-lapse. Inherited provisional names used unchanged: DELEGATE, SIM, FIXED, FU, conduct, rule, selection, quantity, well-timed, v̂⁺, P_n, V_n, M(p), token responsiveness, responsiveness squeeze, report coordinate, extensional criterion, scheme.

No authorization token and no cryptographic story is proposed or implied. The object here is an option set and a map on it. κ is a set-valued function, not a credential; ⊥ is an effect, not a failure code; nothing is signed, and nothing in the interface is secret.

9. Maintainer decisions surfaced

9.1 The reference question this raises

**Is Reach-properness the right formalization of "the principal has authority"?** Theorem 6 says that if the concept is "the agent cannot bring this about", the capability form is forced and nothing weaker states it. It does not establish that the concept is that. Two readings the mathematics does not choose between:

Reading 1 — authority is inability. Then Definition 3 plus Definition 5 is the whole content, the theorem is Theorem 6, and the programme's job is architectural: exhibit systems where Reach is proper and report-attributable, and defend H1–H6. Cost: nothing about authority is checkable from behaviour, ever (Theorem 11), and the paper must say so in its own voice rather than in a limitations section.

Reading 2 — authority is inability plus provenance. Then report-attributability is not enough, because ρ itself may have been authored (§1.7, last consequence), and Movement VI is not downstream work but part of the definition. Cost: the interface grows a principal-side model, and the weakest-interface claim of §1.4 is claimed for the wrong statement.

I did not choose. Choosing is AGENTS.md's reference question and it is reserved.

9.2 Proposed skeleton clause — FINITE_MODEL_SKELETON v2, §4a

Stated as a versioned patch, not installed. Skeleton v1 has no execution layer, so no non-conferral proposition is expressible in it; that is the deficiency this item found, and it is Phase I's Deficiency 1 seen from the architecture side.

**New carriers, per decision index n.**

object	type	constraint
R_n	finite set of reports	nonempty
ρ_n	Ω → R_n	F(n)-measurable
ι_n	R_n → Π_n	the intervention a report designates
⊥		the null effect; Π_n^⊥ = Π_n ⊔ {⊥}
E_n	Π_n × R_n → Π_n^⊥	E_n(ι_n(r), r) = ι_n(r)

Derived: κ_n(r) = E_n(Π_n × {r}).

Amendment to §1. X_{n,π} is indexed by π ∈ Π_n^⊥, with |X_{n,⊥}| ≤ B. X_{n,⊥} is a declared per-instantiation modelling commitment.

Amendment to §4. A conduct is a proposal α : Ω → Π_n with a declared information time; its realization is ω ↦ E_n(α(ω), ρ_n(ω)); its quantity is ω ↦ X_{n, realization(ω)}(ω). DELEGATE has α = ι_n ∘ ρ_n; SIM has α = Ĵ_n. The v1 selection is the realization, so §4's distinctions survive unchanged.

What the clause does not add: no probability on reports, no admissibility restriction on conducts, no causal calculus, no token and no cryptography. Whether a given instantiation protects anything is the properness of κ_n, declared per instantiation and per state.

Proposition 2 (the patch is conservative). With R_n = Π_n, ι_n = id, ρ_n = J_n and E_n(π, r) = π, the v2 objects reduce to v1's: the realization is the proposal, κ_n ≡ Π_n, and ⊥ is unreachable. Every v1 statement is a v2 statement about this instantiation. ∎

Rerun or reconcile, per DISPATCH_QUEUE.md. Tracks B, C, D and G bind to v1; A, E and F do not.

• D (item 17, channel) — reconcile. Its Propositions 1–8 are about the free instantiation of Proposition 2 and survive verbatim; the reconciliation is one sentence naming that instantiation.
• B (item 15, settlement) — reconcile. Its classification and its 2B underwriting bond are statements about the free instantiation. Proposition 1 above suggests the bond and κ are two points of one scale, which is new work rather than a correction.
• C (item 16, certificate) — rerun recommended. Fail-closed becomes expressible for the first time: ¬Cert can mean the proposal is unauthorized and the effect is ⊥. The roadmap says explicitly that "a model carrying no capability structure cannot discharge" this obligation, and v1 is such a model.
• G (item 20, admissibility red team) — rerun recommended. A restriction on the conduct set is now nameable as a capability assignment (Theorem 6), so the red team should re-ask whether its candidate families are κ-statements in disguise.

9.3 Two decisions the clause forces

**X_{n,⊥}.** Theorem 9 puts all of protection's valuation content in it. Scoring the null effect at 0, at the status quo, or at a worst case are three different theories of what refusal costs, and the round should not pick one silently.

Whether the null effect is the right shape of failure at all. Under strict protection the agent's only deviation is refusal (Theorem 8b), so an agent that cannot override can still obstruct. Preventing obstruction needs ⊥ ∉ κ_n(r) for authorized r, which leaves the agent no discretion whatever and contradicts the roadmap's quantitative-autonomy commitment. Categorical authority against override and categorical liveness against obstruction cannot both hold while the agent has any discretion, and the architecture has to say which it is buying. Fail-closed as stated buys the first.

10. Next recommended theorem or experiment

In order of value.

1. Port Theorems 1, 2, 6, 11 and 12′ to Lean. All are finite and one to four lines; Theorem 6 is the only one with content. That converts the necessity result and the impossibility from hand arguments into lean-proved, which is what a result that is meant to stop work should be. It is PRIORITIES.md 23's kind of work and needs no decision in front of it.
2. Rule on the §9.2 patch, because item 16's rerun is blocked on it and fail-closed is currently inexpressible.
3. Attack Definition 5. Report-attributability is the clause carrying the difference between authority and inability, and it is the one I am least confident is right. Concretely: construct an interface where Reach(ω) = FReach(ρ(ω)) holds for a reason having nothing to do with the principal, and see whether the definition admits it. If it does, Definition 5 is too weak and the fix probably requires the variation register Phase I priced.
4. **Cross-decision Reach.** Phase I's Deficiency 2 is untouched, and foreclosure — A removing the principal's later ability to correct — is a statement about Reach at a later index conditioned on a realization at an earlier one. The interface here is one index deep. My conjecture, unargued: foreclosure is the statement that Reach_{n₂} depends on ⟦c⟧(ω) at n₁, which the capability vocabulary states cleanly and the extensional vocabulary cannot state at all.
5. The graded-capability scale (Proposition 1). If underwriting and architecture are two points on one cost scale, the interesting question is what the intermediate points buy, and whether a finite cost can be made preference-independent.

Outstanding maintainer actions

1. Persist this report. The executing agent's harness refused to write REPORT.md; the content was returned as text and must be committed to prompts/2026-08-11-phase-ii-authority/REPORT.md unchanged. (Discharged by the orchestrator, 2026-08-11.)
2. Rule on the §9.2 skeleton clause. A revision is a version bump in FINITE_MODEL_SKELETON.md §10 plus the reconcile/rerun decision of §9.2 for tracks B, C, D and G. Item 16's fail-closed obligation is inexpressible until this is decided.
3. Decide §9.1 — whether authority is inability, or inability plus provenance. Record in DECISIONS.md. It decides whether Movement VI is downstream work or part of the definition.
4. **Decide X_{n,⊥}** (§9.3, first paragraph): what the null effect is scored at. All of protection's valuation content is in that number.
5. Decide which of override-protection and liveness the architecture buys (§9.3, second paragraph). They are incompatible while the agent has discretion.
6. Decide whether to file the four proposed entries. They are demand-gated to item 22 and pass today. To register: create projects/deference/CLAIMS.md, move the four entries from prompts/2026-08-11-phase-ii-authority/CLAIMS-proposed.md into it unchanged, and confirm with python3 -m checkers.run "$PWD/projects/deference/CLAIMS.md".
7. Re-sequence on Theorem 10. Phase I's outstanding action 1 blocks WP-C on the §9.1 decision; that block is now known not to apply to the architecture layer.
8. **checkers/run.py:131 is still unfixed** — Phase I's outstanding action 4. path.relative_to(ROOT) still raises on a relative command-line argument, so the re-verification command in §3 must use an absolute path. Specification layer, so mine to report and yours to change.
9. Amend the roadmap's lapse list. The standing commitment "the guarantee lapses entirely if A can forge, bypass, rewrite or seize the protected channel" names four conditions that are three at the level of reachable effects, and omits a fifth — fixity of the world semantics — which §1.7 shows is independent and carries the whole safety value of the null effect.
