Inline comments:
In `@crates/tinyhivemind-core/src/approval/mod.rs`:
- Line 34: Update the Resource branch of scope_covers to require both
held.target and requested.target to be ActionTarget::Resource paths within root.
Preserve the existing Action branch and shared validation so the rule applies
consistently to StandingGrant and RememberedRefusal.
In `@crates/tinyhivemind-hive/examples/bench/decision_eval/mod.rs`:
- Around line 66-67: Update the hybrid.parallelism assignment in the decision
evaluation setup to use the minimum of options.jobs.max(1) and
JEV_MAX_IN_FLIGHT, preserving the existing u64 conversion and fallback. Keep
baseline.parallelism unchanged.
In `@crates/tinyhivemind-hive/src/quorum/mod.rs`:
- Around line 256-257: In the evaluation fold, check horizon.within for
evaluation.source_sequence before calling validate_evaluation, continuing
immediately for expired evaluations. Keep validate_evaluation for in-window
evaluations, then apply the violation-probability filter without changing the
existing behavior for current sources.
- Around line 262-264: Update the evaluation aggregation around latest.entry so
duplicate evaluations with the same agent_id and source_sequence cannot produce
order-dependent results: reject conflicting probability values or select a
deterministic canonical evaluation. Preserve replacement of older entries by
newer source_sequence values and ensure probability_support and consensus are
invariant to input ordering.
In `@crates/tinyhivemind-hive/src/quorum/types.rs`:
- Around line 204-205: Update the rustdoc for TopicStanding::carried to describe
checking probability_support against the scaled threshold after the refutation
cap, rather than counting supporters. Also revise the corresponding README
refutation paragraph so it consistently describes expected weighted support and
no longer claims carried reads supporter count.
In `@crates/tinyhivemind/src/approval/mod.rs`:
- Around line 78-90: The approval answer validation currently requires exact
scope equality, rejecting narrower valid grants and refusals. Update the checks
in the ApprovalAnswer grant and refusal branches to validate that the claimed
scope is contained by the offered scope, using the rules in
docs/specs/approval.md including lexical containment for Resource scopes. Add
coverage for each valid narrower scope for both StandingGrant and
RememberedRefusal while preserving rejection of out-of-scope answers.
In `@crates/tinyhivemind/src/approval/types.rs`:
- Around line 48-49: Update the AskOutcome contract and ApprovalGate::ask_once
flow so Already represents only a pending record; when a completed record
exists, return Answered with its approval or refusal, allowing request_approval
to expose the final decision.
In `@docs/specs/README.md`:
- Line 74: Move the approval.md entry from the “Draft and proposed
specifications” section to “Accepted specifications,” preserving its existing
link and description so the index reflects its implemented status.
In `@README.md`:
- Around line 112-116: Reduce README.md to 500 lines or fewer, preferably by
moving the detailed standings_with_evaluations explanation into a linked module
document while preserving essential README guidance and adding a clear link to
the relocated details.
In `@ROADMAP.md`:
- Line 39: Update the roadmap entry identified by its P25 label so every roadmap
item has a unique identifier; rename this entry or adjust the later conflicting
entry while preserving the existing roadmap ordering and content.

Count missing evaluations as failures
A supporter with no admitted evaluation is silently skipped, exactly like a supporter that is not being considered. For example, if a topic has two structural supporters but only one supplies an in-window evaluation, this loop contributes only the one available probability and provides no explicit failure for the missing decision. Treat every structural supporter as an evaluated decision—mapping an absent or rejected evaluation to zero support (or otherwise recording the failure)—so the quorum cannot be satisfied by silently dropping missing decisions.

Validate probabilities during deserialization
These newly public serde payload types deserialize Probability fields without enforcing the documented [0, PROBABILITY_SCALE] range. standings_with_evaluations checks the values only when that specific fold is called, so malformed deserialized values can still be constructed, retained, serialized, or consumed by other public code before admission. Give Probability a bounded deserializer or apply validation in the deserializers for these payload types so invalid wire data cannot enter the API.
