 | I16 | When a test outside your task fails, check once whether it fails without your change (stash, run, unstash), then stop and report both results. Do not keep experimenting, and never add a file the task does not list, not even a temporary one. | M5a task 21: the session did the check, then spent about 80 minutes on experiments and wrote two diagnostic test files into `crates/bxctl/tests/` until the owner stopped the run; the cause was outside the repository (review finding 4). M5a task 16 did it right: one check, its log row, a stop. | yes | M5c-1: the stash left the new untracked tests behind and a baseline printed no total (task 15; now `git stash -u` in AGENTS.md, T53); the two flaky tests were rerun and named, not stopped on (now an exception for a test the README lists, T52). |

 ## Tips for writing tasks
 
@@ -91,11 +92,13 @@ How it is used:
 | T51 | Never tell the implementer to run a command that the harness denies or that AGENTS.md forbids. Write the branch line as a check ("`git branch --show-current` prints `m5c1`"), not as `git switch`. | M5c-1: all fifteen transcripts start with a refused `git switch m5c1`; AGENTS.md forbids switching branch. |
 | T52 | List the known flaky tests in the plan README, with what to do (a test outside the task that fails once, then passes on a rerun and in the gate, is named in the log row's Notes and the task goes on). Before hand-over, stress the whole workspace under load, not only the new tests (T32). | M5c-1 task 01: gatewayd's `brokerd_closing_first_ends_it_as_no_longer_pending` (2 of 10 runs fail on a loaded talos with no M5c-1 change); task 15: loopd's `pointers`. Both older tests; Laguna went on in both cases, and task 01's row calls a different test "the only flake". |
 | T53 | Give the baseline in the task so the implementer never has to measure one. Where a check without the change is needed, the stash is `git stash -u`: a plain stash leaves the new untracked tests behind, and they no longer compile. | M5c-1 task 15: a baseline run printed an empty total; task 03 moved the new tests aside by hand before stashing. |
-| T54 | Give an import change as a single added `use` line, never as a rewritten import block: the implementer's Edit retypes the lines around it, and the next task's "before" block stops matching. | M5c-1 task 12: its W1 edit rewrote the import block in another order, W2's "before" block then failed to match, and Laguna anchored on its own line instead of stopping (logged as "Deviations: none", I17). Task 06: an M2 replacement landed in the wrong `match`. |

M5c-2: tasks 06, 07 and 10 rewrote import blocks again; 06 restored rustfmt's order before the commit, 07 anchored H2 after H1 reordered uses. |
 | T55 | Put "its spaces are checked" on every edit to a literal whose whitespace matters, not only the first. | M5c-1: task 04's C1 had the note and was right first time; task 14's U1 did not, and got one extra leading space (caught by a test; the row blames the task). |
 | T56 | When a task uses an external crate, say that the task's table of its API is complete and that the crate's source (the Cargo registry) is outside the repository and off limits; better, put the signatures needed into `files/`. | M5c-1 tasks 10, 11 and 13 each tried to read `roncho`'s source in `~/.cargo/registry` (`find / … roncho`); only the harness stopped them. |
 | T57 | Split a task that combines skeleton fills with more than about fifteen before/after edits over four or more files. | M5c-1: tasks of one skeleton or only listed edits took 6 to 14 minutes; 09 (18), 15 (20, 17 test files and about 30 edits) and 13 (25, two skeletons and ten edits) were the slow ones. |
-| T58 | For a class ceiling or trust rule in a spec, list every path that writes to the egress it guards (turns, mirrored memory writes, undo, review accept, notes) and give each path a test at the forbidden class. A rule written for one path is not checked on the others by default. | M5c-1 review finding 1: the `secret` ceiling was built and tested for turns only; memory writes from a `secret` session were mirrored to the trusted and fleet workspaces (the reference had it too). Finding 2 is the same shape for undo. |

+| T59 | After `gate: ok`, the task is done counting. Do not tell the implementer to run `cargo test --workspace` (or the gate) again only to compare a number. AGENTS.md already forbids a second gate "only to count"; say the same of the workspace test run. | M5c-2: all twelve sessions ran `cargo test --workspace` after a passing gate to rediscover the total, even with T50's wording in the task. |
+| T60 | The driver must not truncate a task's run log, and must not start a task whose commit and `done` row are already in HEAD. A power-loss resume continues the existing log file; it does not open it for write from offset zero, and it skips a task that is already committed. | M5c-2 task 05: `.state/runs/M5c2/05-memoryd-honcho-readers.log` is four `=== …` resume sections after HEAD was at task 12; the original transcript is gone.

+
+Accepted, with one test-only fix made in review (below). Tasks 01 to 12 by Ornith-1.5-35B-A3B
+through `tools/run-plan.sh`, run on talos 2026-09-28 to 2026-09-29, device-checked on straylight
+2026-10-02 (UTC 2026-10-03). The branch differs from the reference (`~/boxmaker-refs/m5c2-ref.bundle`
+on straylight, `d051c89`) in three skeleton bodies only (`honcho/recalled.rs`, `search.rs`,
+`ask.rs`), each an equivalent rewrite; `read.rs`, `client.rs`, `config.rs` and `start.rs` match
+the reference, including task 05's `read.rs` against both the given file and the reference.
+
+| Check | Result |
+|---|---|
+| 12 task commits, each with `Co-Authored-By: ornith-1.5-35b-a3b <agent@wntrmute.dev>` | pass |

+| Independent review of `git diff master m5c2 -- crates` against the spec (T58) | one finding, below; sound: fleet and untrusted-read hits taint, a trusted read workspace's do not; own workspaces never searched by `recall`; a key-shaped query or question sends nothing; no Honcho call under the state lock; keys and bodies never logged; Honcho and local text one indented line (T37); `ask_memory` at most two workspaces at `minimal`; waits 170 s / 180 s |
+
+Task 05's run log `.state/runs/M5c2/05-memoryd-honcho-readers.log` is a resume after HEAD was
+already at task 12 (power loss wiped the original transcript). Commit `b370c60` matches the task
+and the reference; Laguna did not re-commit. Task 06's row records an import reorder by the edit
+layer, restored to rustfmt's order before the commit; `d8c396e` only adds `pub mod recalled` and
+makes `when` `pub(crate)`. The `honcho_worker` flake listed in the plan README did not fire.

+| # | Severity | Where | Finding | Resolution |
+|---|---|---|---|---|
+| 1 | medium | plan (task 12; the reference too) | Spec 8 and 13: a `secret` session's `recall` and `ask_memory` still query Honcho. `serve.rs` ignores `MemoryCall.taint` on those paths, and the unit tests cover `has_secret`, but nothing at the serve layer against the fake Honcho pinned a `secret` taint (T58). | Review `f808426`: `a_secret_session_still_asks_honcho` in `honcho_recall_serve.rs` and `honcho_ask_serve.rs` |
+| 2 | nit | tests | A few recall tests share the fleet fixture with a read-agent workspace, so they do not isolate an untrusted read-agent from the fleet. Behaviour is still labelled by source. | Noted |
+| 3 | process | driver (task 05) | A power-loss resume truncated the task's run log and continued from HEAD at task 12. The commit itself is complete. | Tip T60; AGENTS.md: stop if the task's commit and a `done` row are already in HEAD |

+|---|---|
+| Agent 2 writes a fleet note | `MemoryCall` with `untrusted: true` to agent 2's `run/broker-memory/memory.sock`; in `boxmaker-check-fleet` as peer `boxmaker-check2`, text `M5c2-check: boxmaker-check2 tea stocks are low`, within 2 s |
+| `recall` of that note | Direct `MemoryCall` and a `bxctl chat` turn: `[1] memory-tainted · fleet: boxmaker-check2 said, 2026-10-03 03:18 UTC · private`; `TurnDone.untrusted` true |
+| `ask_memory` of `own` | First `bxctl` turn: `own: unavailable` (HTTP 404; the trusted workspace did not exist yet, the same answer the tests give a missing workspace). After that turn had been mirrored: `[1] memory · own · private` with a dialectic paragraph, within the limit; `TurnDone.untrusted` false |
+| Honcho unreachable | agent 1's `memoryd` restarted with `HONCHO_URL=http://127.0.0.1:1`; `recall` of `tea stocks` returned two local hits plus `boxmaker-check2: unavailable` and `fleet: unavailable`; log: `Honcho is unreachable (connect)` |
+| `make verify-device` | 6 passed in 24 s, `verify-device: ok` (slot 0, `UPSTREAM=127.0.0.1:11434`); the baseline with `ask_memory`'s schema still fits the 3,000-token budget |
+
+What was good: twelve tasks, first-gate pass in every row, no stop, skeletons filled to match the
+reference in behaviour. The one product finding was a missing test of a path the code already
+took.
+
+Open items carried forward: rift's dialectic at `reasoning: low` still returns raw tool-call
+markup (`ask_memory` stays at `minimal`); turn numbers restart per epoch; a `bxcore` function for
+`sanitize::refuse`'s secret rules to replace `has_secret`; Mattermost usernames `a.b` and `a_b`
+map to the same Honcho peer; queries from `secret` sessions go to Honcho on the assumption in
+spec 8 and `docs/egress.md`.
