loopd's self-test caught the change (context per slot 131072 -> 262144,
slots 2 -> 4). The device tests keep the expectation in one constant, and
the M3a script matches it; verify-device passes 6 of 6 and the M3a device
check passes. The inference contract notes which M0 findings rest on the old
layout and need re-measuring.

M3a review findings 9, 10, 12, 13. A retrying error and every error detail
can carry the inference server's body, so they are escaped like model text.
Admin requests wait at most 30 s, so a stuck brokerd cannot hang bxctl or a
chat turn. A failed write is AdminError::Io and stops handle_pending instead
of being answered with another write. The usage line says what audit verify
checks.

M3a review finding 8. The wait was expires plus the timeout with no bound,
and the "expiry too far away" guard could not fire, so a far expiry (which
brokerd produces when now + ttl_ms does not fit) parked a turn for ever.

M3a review finding 7, for the other three roles. loopd keeps its config path
as a path; bxctl and inferproxy take text arguments and answer one that is
not UTF-8 with their usage.

M3a review findings 3, 5 (the cast), 6, 7 (brokerd), 11. A config, directory
or socket failure at start now ends with docs/runbook.md#brokerd-start-failed,
and losing a listener with #brokerd-listener-lost; both entries are new.
Threads start through thread::Builder, so a refused thread is reported
instead of silently killing a listener; an aborted connection no longer stops
the daemon. brokerd reads args_os and keeps the config path as a path. The
"requester went away" result is recorded at the time it happens.

M3a review findings 1, 2, 4 and part of 5. One empty log file made brokerd
panic at startup (files[len - 2]); it now opens as an empty log. brokerd's
name check tested one month digit, so a file bxctl ignored could become
brokerd's latest file; both now use proto::is_audit_log_name. Writer no
longer unlinks audit/.lock, which opened a two-writer window. No unwrap in
short_check.

hold_open (d21baa2) kept each connection open for up to two seconds
after its final frame, reading and dropping anything the peer sent, to
hide a test client that set a read timeout after the handler had closed.
On macOS that call fails with EINVAL; the clients now allow for it
(00a85c1, d7009dc), so the handler goes back to closing at once.

The test client set its read timeout before every frame. On macOS that
fails with EINVAL once the handler has sent its final frame and closed,
so every admin test that reads a second frame failed there (40 runs of
40 at 2408e2c). The frame is already buffered, so the client now takes
that one refusal as the peer having closed and reads it. The plan's copy
changes with it.

macOS refuses every socket option with EINVAL once the peer has closed
(XNU sosetoptlock, bsd/kern/uipc_socket.c), even with unread data still
buffered. loopd set a read timeout before each read, so on macOS every
frame or response that arrived just before the peer closed was lost:
BrokerPort reported the broker unavailable with "os error 22", and the
llama client failed the same way. Twelve loopd test binaries failed on
macOS; Linux never refuses, so the gate on Talos did not see it.
Both places now go through socket::set_read_timeout, which on Apple
targets takes that one refusal as success: a socket shut in both
directions returns its data or the end at once and cannot block. A
zero timeout is still an error.

Debug collection commit for the brokerd admin-test hang investigation (M3a
task 19). Contains:
- crates/brokerd/src/broker.rs: hold_open helper (HOLD_OPEN = 2s read-timeout
loop) applied after forbid and after the final send in broker::handle
- crates/brokerd/src/admin.rs: hold_open applied after forbid and after the
final send in admin::handle
- crates/brokerd/src/grants.rs: check_tool_constraints refactor (match guard
instead of nested if)
- docs/M3a/DEBUG-HANDOFF.md: investigation results added (310 runs, zero
hangs reproduced; stalled fsync cannot be fixed without dropping durability)
The implementer log row was committed separately (a6d81d9).

Implemented decide and redecide in crates/brokerd/src/policy.rs:
SessionState, Label, Denial, private Matched, and Decision/Ask (private
fields, Debug only, nine getters each) with the Outcome enum. decide
rejects an unknown tool (args not parsed) and malformed arguments before
matching, then runs the M1-M5 matching pass in id order and returns
Allowed/Ask/Denied by the winner's mode; redecide re-runs matching now
and rebuilds the Decision from the Ask. Seven doctests (six compile_fail,
one compiling) guard the two facts. policy 7, policy_matching 10,
policy_redecide 7, policy_property 4, doc 7 all pass; make gate ok.

crates/brokerd/src/grants.rs reads grants/*.toml into a GrantSet: load reports every problem in every file and returns either a complete valid set or the full problem list, never a partial one; from_grants sorts by id and collects every rule-2..9 problem; render prints each problem then the runbook pointer. All 17 grants tests pass; make gate prints gate: ok.

Implemented brokerd::args: a pure module (no I/O, no clock) that parses tool
arguments into a typed ToolArgs and checks the form of paths, hosts and URLs.
Four private deny_unknown_fields structs drive parse and canonical_json; path,
cwd and url are validated as written and never normalised. All 13 args tests
pass and make gate prints gate: ok.
Implemented-By: OpenCode session (model recorded in docs/implementer-log.md)
Implemented crates/brokerd/src/config.rs: typed Paths, Sockets, Approvals and
Config with serde(deny_unknown_fields, default) on every struct, hand-written
ConfigError (Read/Parse) with Display and std::error::Error, and the parse/load/
broker_socket/admin_socket/audit_dir/state_dir methods. Added serde, serde_json
and toml to crates/brokerd/Cargo.toml, registered pub mod config; in lib.rs,
added brokerd to the serde and serde_json Used-by cells in docs/dependencies.md,
and copied the given test and six fixtures byte-identical. 7 config tests pass;
make gate prints gate: ok.
Implemented-By: OpenCode session (model recorded in docs/implementer-log.md)
Implemented proto::ChainVerifier as a pure line-holding state machine:
each line is judged only once the next has arrived, so a Recovery record
can mark the line before it not-a-record. Adds ChainFailure, TornTail,
ChainReport, Location and ChainVerifier, wired through lib.rs and the
matching re-export in audit.rs. 13 chain tests pass; make gate prints
gate: ok.

Implemented SlotGate (one request in flight per server slot, FIFO queue,
bounded) and chat_with_retry (retry only server-gone errors, jittered
backoff within a window and attempt budget). chat acquires the gate and
maps GateFull to Busy; Client gained a gate field.
