broker/sessions/<id>.json holds each session's taint and untrusted
flag. It is written only by brokerd and can be rebuilt from the audit
log's result records.

brokerd internals: the ledger lock over the audit writer and session
state, the pending table's take-it-and-answer rule, sticky
audit_unavailable after a failed write, pure policy functions with an
Ask type that only redecide turns into a Decision, how a waiting
thread detects a lost connection without peek, fixed RunError text.
Approvals: bxctl chat fetches the block from brokerd by id, shows the
parsed arguments with invisible and bidi characters escaped, asks for
the approval id instead of y, and escapes model text. A tool_denied
event carries the reason to the owner.
Also: BrokerPort timeouts, tests for runbook pointers and concurrency,
threat-model notes, P14 for broker/sessions in the brief's State list.

Policy: a deny grant must apply at every taint; a result's label is
combined over all matching grants and the longest matched path wins
within a mode; a grant of / is invalid.
Audit: a recovered line need not fail to parse; the writer never goes
back to an earlier day's file; --accept-break verifies the whole log
and the break record's fields are all checked, with a seq counted from
lines; the Approval record carries the re-decision's grant and state;
calls with no Result are reported.

Split M3 into M3a and M3b, record the M3 design decisions, propose P13
(tool image built by Nix, named by digest), and add docs/runbook.md with an
entry for every fail-closed state, including loopd's existing ones.
