kyleandClaude Opus 5.5 e08deb39a6 brokerd: recover a torn line in place, real dates only, bounded ttl, EMFILE
From the independent review of task 23. A torn last line followed by an empty
later file had its recovery written into the later file, which broke the
chain for good; the line is now ended in its own file. The log-name rule
takes months 01 to 12 and days 01 to 31 only. [approvals] ttl_ms is limited
to a day, the longest loopd waits after a pending frame. Running out of file
descriptors or memory pauses the listener instead of stopping brokerd (the
errors the previous fix skipped do not occur on Linux). args.rs's doc fixed.

kyleandClaude Opus 5.5 ba369f82ba brokerd: refuse / and a symbolic link as a socket's directory
brokerd makes a socket's directory 0700. With a socket directly in / it would
chmod /, and through a symbolic link it would change the link's target. Both
are now refused at start with #brokerd-start-failed. Without the fix the link
case started and served, with the shared directory made private.

kyleandClaude Opus 5.5 6af89f7c60 brokerd: runbook pointers for startup failures, no thread panics, args_os
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.

kyleandClaude Opus 5.5 eed0a221ca Audit writer: open a record-less log, share the log-name rule, keep the lock file
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.

kyleandClaude Opus 5.5 57dc7899a9 brokerd: close the connection after the final frame again
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.

kyle d21baa2954 Debug collection: hold_open fix, grants.rs refactor, and DEBUG-HANDOFF findings
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).

kyle e1e6c7a338 Decide tool calls against grants, taint and time
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.

kyle e2ab29aa15 Load grant files, failing closed on any invalid file
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.

kyle 9150effc8e Add typed tool arguments and the form checks for paths, hosts and URLs
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.

kyle 5502de1c90 Add brokerd's configuration
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.
