Answer the second SPEC-v0.10 review round: fourteen findings, and two edits a script dropped - #175

Conversation
A second adversarial round against SPEC-v0.10 returned fourteen findings, ten of them introduced by the first round's answers. That rate is what SPEC-v0.9 section 13.8 predicts: about half of a second round's defects come from fixing the first's. The one that mattered is section 3.4.3. It said Control._suspend runs inside the execute call that was given the hop, so reading the hop from a context variable was safe. It is false on every round after the first: _outcome's own docstring says execute and resume both come through it, and _suspend is called from inside _outcome, so round two onward reaches the lease extension from resume, whose ambient context belongs to the resuming process. Item 1 shipped the parameter instead; this makes the document say what shipped, and states that any behavioural test of it must suspend twice because a single suspension exercises only the round the draft was right about. Also: rule 2's data.dimension contradicted section 3.3's "the id and nothing else" and T483's exact key set. The line is now drawn once, in one place, with a table: a refusal may name the row that stopped it and may never carry what the envelope contains. Section 9 gains the two rows item 1 needed and the document did not name, AuthorityResult.hop and AUTHORITY_HOP's place in REASON_PRECEDENCE. Control.hop takes an optional action_id rather than reading an ambient one, because a relay hopping from a worker thread would write None silently, and section 8 records the resulting limit. Three places still said "load error" after section 4.4 established one cannot be implemented. tls_cert_file had broken the rotation story tls_cert_sha256's list was written for, measured against a real listener. And T491's NotExecuted claim is false behind a proxy by gateway/transport._observed's own deliberate rule, which is an argument for check 2 rather than against check 3. Section 2.3.3 said "three of the six" above a table printing four. Two edits from the first round's answers never reached the file: a Python script raised on its last replacement before writing, so the ordered-list correction to section 5.2 and the G25 construction detail in section 7.1 were lost while PR #173's body claimed both. Both are restored here. Round two independently re-found the first; on the second it overruled round one, having built the shape and measured that the detection is deterministic rather than a coin flip on id order, and that measurement is what the section now records. 55 line citations, all resolving.

- Around line 1180-1183: Update the “two known-unaligned cases” discussion to
explicitly enumerate all three precedence-conflict cases, including the missing
case, and map T499a and T500 to separate cases. Keep T498’s generated property
distinct from these named acceptance criteria and preserve the existing
distinction between the full path and _secure.
- Line 1512: Update the AUTHORITY_HOP definition in the reason table to name
only its two permitted cases: a missing delegation and a delegation shape
mismatch. Remove the broad “no live delegation” wording, and explicitly exclude
revoked or expired hops because they must retain their lifecycle-specific
reasons.
- Around line 764-768: Add distinct acceptance-table entries for T488a, T488b,
and T491b, including each test’s required assertions and the proxied AMBIGUOUS
outcome where applicable. Ensure the entries make T488a’s hop-shape requirement,
T488b’s absence of _HOP reads, and T491b’s specified behavior independently
traceable.
- Line 1622: Update the “A swapped upstream at handshake time” row in the
handshake outcome table to qualify its NotExecuted/FAILED behavior as applying
only to unproxied connections, and separately state the proxied outcome if
required by §4.3, including the possible AMBIGUOUS result after CONNECT bytes
are written. Keep the T491 and T491b distinction consistent.
- Around line 1403-1406: The §7.1 construction must match scenario function
g25(): describe the wider candidate as a sibling hop created from the parent by
the same controller, not as a grant owned by the receiving principal. Remove the
claim that only one candidate passes, and state that both narrow and wider
presented hops are asserted with the presented delegation ID determining the
result.

Define distinct acceptance tests for T488a, T488b, and T491b.
The acceptance tables define only T488 and T491. The suffixed identifiers appear only in prose, so their required assertions and the proxied AMBIGUOUS outcome are not traceable. Add separate table entries for all three identifiers.

Enumerate the three precedence-conflict cases and map T499a and T500 separately.
The paragraph claims three cases but lists only two. T499a and T500 both describe policy_unapproved against a later refusal. Name the missing case and assign each acceptance test to a distinct case. The generated T498 property does not resolve this ambiguity in the named acceptance criteria.

| The construction is therefore: a second hop to the same receiving principal, wider than the first, | ||

Align §7.1 with g25()
docs/SPEC-v0.10.md still describes the wider candidate as the receiving principal’s own grant and says that only this grant passes. However, src/ctrlrun/verify/scenarios.py:g25() creates sibling with control.hop(parent.id, wider, by=by), then evaluates the narrow and wider presented hops and expects each presented delegation ID to decide. No direct grant owned by the receiving principal is created. Update §7.1 to describe the wider sibling hop and remove the single-candidate claim. Otherwise, the documented deterministic-selection assertion does not match the reachable scenario.

Define AUTHORITY_HOP with its two exact cases.
§2.3.2 limits AUTHORITY_HOP to a missing delegation or a shape mismatch. §2.3.2 rule 3 assigns revoked and expired hops to their lifecycle-specific reasons. Replace “no live delegation” with wording that names the two AUTHORITY_HOP cases and excludes lifecycle failures.

Limit this row to unproxied connections.
§4.3 states that a proxied TLS failure can occur after CONNECT bytes are written and can produce AMBIGUOUS. State the proxied outcome separately, or qualify this row as unproxied. T491 covers the unproxied case; T491b covers the proxied case.

Round two of the required spec review, and its answers. Documentation only.
Fourteen findings, ten of them introduced by round one's answers. That is the rate
SPEC-v0.9 §13.8predicts, and it is why the build plan budgets more than one round per item.The one that mattered, and it had already shipped
§3.4.3 said
Control._suspend"runs inside theControl.executecall that was given the hop, onthe same stack, so the ambient value is this action's by construction."
False on every round after the first.
_suspendis called from inside_outcome(
control.py:2029), and_outcome's own docstring says "executeandresumeboth come throughhere". So round two onward reaches the lease extension from
resume, whose ambient context belongsto the resuming process: unset, or holding an unrelated hop that would then decide this action's
extension.
tests/test_attempt_cap.py's five-round run already proves the shape is the designedcase.
I caught this while implementing item 1 and shipped the parameter instead (#174). This makes the
document say what shipped, and adds the rule the test needs: any behavioural test of this must
suspend at least twice, because one suspension exercises only the round the draft was right about.
The rest

It is an argument for check 2, not against check 3authority_revoked"prints the revoked one" asks for an id the refusal does not carryexecuteplus the two_securemethods, and nothing moves for any other reasonTwo edits a script dropped, which I have to report
My round-one answers were applied by a Python script whose last replacement raised before
write_text. So two edits never reached the file: the ordered-list correction to §5.2 and the G25construction detail in §7.1. PR #173's body claimed both were fixed. They were not, and they are
here now.
Round two re-found the first independently. On the second it overruled round one: round one
called the G25 construction unimplementable and a coin flip on
secrets.token_hex; round two builtthe shape and measured that only the receiver's own grant passes the wider action, so
min()has oneelement and a pre-§2.3 build fails every run. §7.1 now records that measurement rather than round
one's argument, and item 1 asserts both id orders anyway because the cost is one loop.
Checks
off-by-one errors introduced in this edit were caught by that check.
T470–T507contiguous plus fivesuffixed (
T488a,T488b,T491b,T497b,T499a).What round two left for a third
Its own list, carried forward: re-attack §3.4.3's repair and ask the same ambient question of
_TASK,_AUTHORITY_GRANT_ID,_AUTHORITY_RESULTand_BUDGET_CHARGESat_suspend; theremaining
_authority_resultcall sites; §5 as a whole, which has had the least attention; §4against a real TLS listener end to end. Round two's verdict on the document was not ready, and
these answers do not by themselves make it ready.
Not merging and not tagging.
