A rabbit sees waves begin, Comment |
The example's host loop held rules that are the episode's, not a host's: an ask opens a conversation that runs first and concludes to the asker (ADR 0023); a stalled desk seat and a silent askee are told once and owed a turn (ADR 0024); a broadcast or an ask made inside a conversation is desk work; a refused completion is explained; a spent budget completes the seat with the work; walls end what will not. Ten live runs found and fixed them there, and no host taking the crates could reproduce them. They are now tinyhivemind-driver's Conductor: the desk episode with a child episode per conversation and the folds between them, driven by a host that appends the rows. It hands the host notes to append, commits to append and report the sequence of, and events to log. Every rule is tested against a journal and nothing else. The example keeps what a host owns: the journal, the prompt, running a turn, and the log, and both offline proofs and the bench are unchanged through it. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
CI also runs a plain cargo test, where the offline module does not exist; the crate example now seats a raw runner against any endpoint with a default config, which is what a host does. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

Import the Future trait before using it
Future is not part of Rust's prelude, and this file does not import std::future::Future. As written, the new support module fails name resolution and prevents the crate from compiling. Add use std::future::Future; alongside the other imports.

Not a compile error: the crate is edition 2024, whose prelude exports std::future::Future (the Future and IntoFuture additions). The Rust job on this head is green with this file as written. No change.

Borrow the utterance while checking its variant
matches!(utterance, ...) matches by value and moves the non-Copy Utterance. The subsequent utterance in the Commit initializer therefore uses a moved value, preventing the driver crate from compiling. Match against a reference instead.

Not a move: matches! expands to a match on the place expression, and a pattern with { .. } binds nothing, so nothing is moved out of utterance. It compiles as written and is used unchanged in the next statement; the Rust job on this head is green. No change.

Skip nudges when forcing conclusions
Wave::begin sets force_conclusions when nothing is due, and the field is documented as meaning that every open conversation concludes without an answer. However, this phase always calls nudge_silent_askees. If an open child has already taken a turn, is not quiescent, and has not been nudged, a no-work wave emits a waiting note/event and calls owe_turn before immediately queueing its forced conclusion. That produces an observable nudge and mutates the child despite the documented forced-conclusion behavior. Only nudge silent askees when the wave is not forcing conclusions.
[RULE] force-conclusion-bypassed ·
There was a problem hiding this comment.
The path was unreachable (a forced wave opens no turns, so no child has turned set), but the intent deserves to be explicit: fc4906d7 skips the silent-askee phase when the wave is forcing conclusions.

Reject starter identities outside the desk membership
Door::starters is public, but open never verifies that each starter is in door.members. For example, members = ["a"] and starters = ["missing"] completes a at once, so the conductor opens a quiescent episode even though the requested route has no runnable seat. Validate that starters are a non-empty subset of members and return an error instead of silently treating every member as passed over.

Fixed in fc4906d7: Conductor::open returns Error::UnknownStarter for a starter that is not a member and Error::NoStarters for an empty list, with a test for both.

Skip nudging conversations that have reached the turn wall
A child that has taken a turn, remains non-quiescent, and has already reached child_turn_wall enters this branch before queue_conclusions handles it. The wave therefore emits a waiting note and Nudged event, marks the child as nudged, and owes it another turn even though the same wave immediately queues its conclusion. This produces an observable nudge and mutates a conversation that is already terminal under the wall policy. Exclude children for which child.is_over(self.policy.child_turn_wall) is true when selecting silent askees.
[RULE] skip-terminal-conversations ·
There was a problem hiding this comment.
Fixed in fc4906d7: a conversation that is over at its wall is not nudged; nudge_silent_askees checks is_over(wall) rather than quiescence. New test: a_conversation_at_its_wall_concludes_without_a_nudge.

Record the askee reply only after the fold accepts it
last_by_askee is updated before apply_committed validates the row. If the askee speaks before its newly assigned turn has been shown, the fold returns Error::UndeliveredAssignment and emits a refusal, but this code has already stored that refused message as the conversation's last answer. A later conclusion can therefore report an answer that was never accepted. Update last_by_askee only after apply_committed succeeds.

Fixed in fc4906d7: last_by_askee is set only after apply_committed accepts the row. New test: a_refused_reply_in_a_conversation_is_not_its_answer, which opens the askee's turn at a stale watermark so the fold refuses the completion, then checks the forced conclusion carries no answer.

Handle an empty candidate list before selecting the primary
A router request with no candidates makes eligible empty, so this fixture panics while constructing the evaluation. The helper accepts arbitrary hive member slices, and an empty or otherwise candidate-less request is a valid edge case for routing tests; return an evaluation/error appropriate to the router contract instead of indexing element zero.

Borrow the routing plan when checking clarification
matches!(plan, ...) consumes the non-Copy RoutingPlan, so the subsequent starters(&plan, fallback) borrow fails with a use-after-move compilation error. Match against a borrow instead, such as matches!(&plan, RoutingPlan::Clarify { .. }).

[RULE] use-after-move ·

Not a move: matches!(plan, RoutingPlan::Clarify { .. }) binds nothing, so plan is intact for starters(&plan, fallback) on the next line. The example compiles and runs as written (both offline proofs and the bench in the PR description ran through this line). No change.

Propagate failures from the conducted episode
The loop records errors with break Err(...), but the resulting settled value is never consumed before the function prints the report and returns Ok(report). Routing, driver, or conductor failures can therefore be silently treated as successful runs. Propagate the result after the loop, for example with settled?;, before producing the report.
[RULE] ignored-result ·
There was a problem hiding this comment.
It is consumed: settled?; is at the end of the report section, after the journal dump and before the offline proof assertion (line 893 on this head). A routing, driver or conductor failure ends the run there. No change.

Filter private rows before building thread context
thread returns every row attached to the thread without checking row.4 (only_for). wave passes this result to each seat's open_turn, so a row intended for one seat can be included in another seat's context whenever it shares the thread. Add the requesting seat to this API and exclude rows whose only_for does not match it, while retaining public rows.
[RULE] private-data-isolation ·
There was a problem hiding this comment.
Same as the thread above: thread rows are never addressed to one seat by the conductor, so the fixture's thread has nothing to filter. Declined.
…swers From review: a starter outside the desk, or no starter at all, is an error rather than a quietly quiescent episode; a conversation at its wall, or one concluding because nothing is due, is not told to answer first; and the answer a conversation carries to its asker is the row the fold accepted, not the one that was tried. Each has a test. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

Summary
Stacked on #67; the diff shows both until it merges.
The
conductedexample's host loop held rules that are the episode's, not a host's: an ask opens a conversation that runs first and concludes to the asker (ADR 0023); a stalled desk seat and a silent askee are told once and owed a turn (ADR 0024); a broadcast or an ask made inside a conversation is desk work; a refused completion is explained to the seat; a spent broadcast budget completes the seat with the work; walls end what will not. Ten live runs found and fixed them in that loop, and no host taking the crates could reproduce them.They are now
tinyhivemind_driver::Conductor: the desk episode with a child episode per conversation and the folds between them, driven by a host that appends the rows. It appends nothing itself. It hands the hostSteps -- aNoteto append attributed to the desk, aCommitto append and report the sequence of throughcommitted, anEventto log -- one wave at a time:begin_wave,turns,open_turn(the brief),record, thenstepuntil the wave settles.Doorandstartersopen the desk from a routing plan.ConductPolicyholds the two walls.The example's loop shrinks to what a host owns: the journal, the prompt, running a turn, and the log lines for events.

Covered: the door and every plan shape; an ask opening a conversation that runs first, concludes to the asker, and is shown once; a completion refused while a conversation is open; a silent askee nudged once and then walled; a broadcast or ask inside a conversation reaching the desk and a dm dropped; nothing due concluding every conversation; a stalled desk seat nudged once per assignment and the episode then stalling; an unplaced broadcast; a placed broadcast completing its author and a handoff to a busy recipient, then an undelivered completion refused; a spent budget discharging the seat; the turn wall; and the commit protocol's two errors.Deliberately untested: a conversation reaching the wall by turns alone rather than by the nudge sequence, which is the same branch.
