+fork commit you made is pushed: the orchestrator removes the worktree once its branch lands.
 
 ## Measure, build, test
 
 Where hardware or anything uncertain is involved, take the cheap measurement before you build on a
-guess. Then build, then test before anyone reviews:
-
-- Host tests only: `cargo run -- --ci host`, and `cargo run -- --build-only` at most for the
-  image. Never a guest test or any other `cargo run`: the orchestrator runs every guest test.
+guess. Then build, then test on root `CLAUDE.md`'s tiers before anyone reviews:
+
+- Host tests with `cargo run -- --ci host`, the image with `cargo run -- --build-only`, and with
+  `cargo test` every guest test your change reaches, the whole suite or a filter. Never a `cargo
+  run` that launches QEMU, nor `--metal` without `--metal-readback`, which touches no machine. For
+  a metal row, `cargo test --test toyos-build -- --metal --metal-readback <dir> <row>`, from a
+  committed tree and with the `<dir>` the brief names, builds its images and writes
+  `<dir>/request.txt`; end your report with `T14 RUN REQUESTED: <dir>/request.txt`.
 - A result is the command's own exit code: `<cmd> > <file> 2>&1; echo EXIT=$?`. A grepped
   `test result` line is not one, and a gate you did not run is a gate you do not claim.
-- Long commands run in the background with output to a file under the job scratchpad the brief
-  names. Stay inside one turn while anything runs: sleep at most two minutes, print a line, check
-  again. Ten minutes of silence kills you, and ending a turn to announce a wait strands the work.

+resumed agent only ever finishes its own interrupted task. There is no limit on branches in flight.

-## Judge
+## Review and land
 
-The reviewer reports, you judge, and a judge who upholds everything is not judging. Only a BLOCKER
-sends a branch back. When a reviewer and an implementer disagree, ask for the measurement that
-settles it and decide. Before ruling on a "blocked" report, read the code and check it against the
-product's principles; never change what a product is to make a check green.
+Start a review whenever one is useful. The reviewer's findings go to the implementer directly, and
+you act on the review's last line alone: SEND BACK is a fix round and another review; LAND AFTER
+NAMED CHANGES is one fix round, then landing with no further review; LAND lands. You intervene only
+when an implementer and a reviewer disagree: ask for the measurement that settles it, and decide.
 
-## Land
+CI capacity is limited: a pull request stays a draft through its rounds, and its review rests on the
+exit codes its body records. To land one, `gh pr ready` and `gh pr merge --auto --merge` put it in
+the merge queue, and several branches ready together land as one batch pull request. When a landing
+changes how agents work, every running agent is told the new way in one line and merges
+`origin/main` before its next round. A red that is not about the diff is fixed at its owner, never
+re-run away; a fix for a red lands ahead of feature work.
 
-Glance before every merge: the title and body as `main`'s record, the diff's size against the
-brief's fence, tests added or deleted, CI. Then `gh pr ready` and `gh pr merge --auto --merge`.
-After a landing, sync the primary checkout. When a landing changes how agents work, every running
-agent is told the new way in one line and merges main before its next round.
-A red that is not about the diff is fixed at its owner, never re-run away, and nothing but a defect
-may turn `main` red.
-A fix for a red lands ahead of feature work.
+After a landing, in the primary checkout: `git pull --ff-only origin main`, then remove the landed
+branch's worktree, which its implementer made: `rm -rf ../<name> && git worktree prune && git -C
+rust worktree prune && git -C rust/library/backtrace worktree prune && git branch -d wt/<name>`.
 
 ## Runs
 
-You keep orchestration state (checklists, queue scripts, run logs, patches) in the session's job

-PR. After a restart, kill every queue, watcher and metal process left from before by PID, found by
-its script path under the job directory, and revert any mutation a killed run left applied. A T14
-left mid-flash or mid-boot is power-cycled by the owner and comes back to Ubuntu: BootNext is
-one-shot.
-
-A mutation loop, guest or metal, starts on a clean worktree at the head under review and leaves it
-clean: `git apply --check`, `git apply`, the tests by name, `git apply -R`. None runs while an
-agent edits that worktree. A queue script passes only flags `src/testargs.rs` declares: any other
-word becomes the run's filter, and a one-test run reports as a pass.
-A run is the whole suite, or a positional filter that reaches any enabled test.
+Orchestration state — checklists, run logs, patches — lives in the session's job directory,
+`~/.claude/jobs/<session>/`, which survives a CLI restart; what a pull request's evidence rests on is

 ## The bench
 
-You alone run the T14, one boot at a time. Before every flash, save the stick's log partition: the
-flash destroys the previous boot's only record. Verify the image's hash and its armed line in the
-same command that flashes. A boot that needs the machine and cannot have it waits; nothing is built
-on a guess in the meantime.
-
-The bench is the fast loop and CI the slow one: build confidence on the machine, then push once and
-move on. Ubuntu on the T14 is recovery, not a tool. Every question the bench raises — a log, the
-link, a device, an update — is answered on ToyOS, and one ToyOS cannot answer yet is a feature to
-build, because the bench's needs are a user's needs.
+You alone run the T14 (`cargo test --test toyos-build -- --metal`), one boot at a time; a report

+image's hash and its armed line in the same command that flashes. A metal mutation loop is a
+measurement, not an edit: it starts on a clean worktree at the head under review and leaves it clean
+— `git apply --check`, `git apply`, the rows by name, `git apply -R` — and none runs while an agent
+edits that worktree. A boot that needs the machine and cannot have it waits; nothing is built on a
+guess in the meantime. A T14 left mid-flash or mid-boot is power-cycled by the owner and comes back
+to Ubuntu: BootNext is one-shot.
