Transcript: wc-3.2, run by a real worker session

The rest of this directory is what replay.sh writes: epic wc-3 played by a script. This file records a real agent session (a Claude Code cloud session, the control-room worker) doing the next piece of the same epic, wc-3.2, under the protocol, on 2026-09-25. Every command below was run, and its output is copied from what came back, trimmed where it says so. Nothing is invented. What was not observed, or was done by this session in another role, is marked Not observed or Role played.

Redactions. The session’s id is session_<redacted>. Paths on the machine are <control-room> (the checkout of this repository) and <scratch> (a throwaway directory). The toy repository’s git identities (worker@example.invalid and the like) and its pull request host (git.example.invalid) are the example’s own placeholders. Nothing else was changed.

1. The brief, as received

The coordinator sent this as a user message in the worker’s session:

EPIC CR-8: branch claude/cr-8-e2e-transcript, scope examples/end-to-end/** (new files), docs/** (a link to the transcript), ROADMAP.md (a CR-8 line), issue #8

## Why

CR-7 landed as db9c545 on main. `examples/end-to-end/` replays one epic as the files the protocol produces; issue #8 asks for the same epic run by a real worker session, recorded beside them, so the protocol is shown working and not only its artefacts.

## The epic

You are that real worker session. Run a small, genuine epic on this repository under its own CLAUDE.md worker protocol, and record it:
1. Choose the epic yourself from what `examples/end-to-end/` already describes, or a small real gap you find in control-room (one that stands on its own; say which and why in the transcript).
2. Record `examples/end-to-end/transcript.md`: the brief as received (this one), each protocol step you took with the command and its real output (trimmed, never invented), the handoff, the READY line, and what the lander checks. Mark plainly anything that was not observed but reconstructed.
3. No private names, sessions ids, paths or tokens in the transcript: redact to placeholders and say that you did.
4. Link it from the example's README and close #8 in the PR description.

Protocol: this repository's CLAUDE.md for workers. End with `EPIC CR-8 READY <sha> <pr-url>`.

It has the fixed shape, EPIC <id>: branch ..., scope ..., so it is a brief and not a question.

2. Starting CR-8 on control-room

This repository’s CLAUDE.md says to check the role first, then branch from a fresh origin/main.

$ echo "${CLAUDE_CODE_REMOTE:-unset}" && git fetch -q origin && git log --oneline -3 origin/main
true
db9c545 Merge CR-7: the coordinator loop — state files, prompts, land-lock, silent-worker rule (PR #10)
31fbe08 CR-7: the coordinator loop, its state files and prompts
bcb7fc2 CR-7: land-lock, and one turn at a time in cr-worker
$ git switch -q -c claude/cr-8-e2e-transcript origin/main && git log --oneline -1
db9c545 Merge CR-7: the coordinator loop — state files, prompts, land-lock, silent-worker rule (PR #10)

true means a cloud worker. The branch starts at db9c545, the commit the brief names.

3. Choosing the epic

wc-3.2, the part of wc-3 this example leaves open. The example ends with the owner’s answer on desk card wc-3-unicode (7-desk/answer.json: choice unicode-spaces, “Yes, and say in the README that scripts without spaces are not segmented”). The README says that answer “goes into the worker’s next brief for wc-3.2”, but nothing shows that happening. Running it continues the same epic, as issue #8 asks. It is small and complete: one behaviour, one test, one README paragraph.

Why not a gap in control-room itself: this brief’s scope allows only new files under examples/end-to-end/, and the one real gap found on the way (section 9) needs a change to tests/.

4. The toy repository

The toy, wordcount, is not published. It exists only as what replay.sh builds, and replay.sh deletes it on exit. So the toy was rebuilt with a scratch copy of replay.sh whose only change is to keep it:

$ sed 's/^trap .rm -rf "\$work". EXIT$/echo "toy repository kept at $work" >\&2/' <control-room>/examples/end-to-end/replay.sh > replay-keep.sh && diff <control-room>/examples/end-to-end/replay.sh replay-keep.sh; sh replay-keep.sh <scratch>/replayed 2>&1 | tail -3
20c20
< trap 'rm -rf "$work"' EXIT
---
> echo "toy repository kept at $work" >&2
toy repository kept at /tmp/tmp.<id>
replayed wc-3: READY bc20c175b461ac96643b6212e15d7939dc0f05d7, landed 9baab710c16d4e16b1ce110f86601b5b3037a2f1
$ mv /tmp/tmp.<id> <scratch>/toy && cd <scratch> && rm -rf toy/worker toy/landing toy/seed && ls toy && git -C toy/origin.git log --oneline --graph main
check.log
landing-check.log
origin.git
red.log
*   9baab71 Merge wc-3: wordcount -w counts words
|\
| * bc20c17 handoff: wc-3 ready
| * c25fff0 wordcount -w: count words (wc-3.1)
| * c71a097 handoff: wc-3 working
|/
* 6997cfe wordcount: count lines

These are the same shas as 5-ready-line.txt and 6-landing.md. The replay’s own worker, landing and seed clones were removed, so that only origin.git, the toy’s remote, carries over. It is a bare repository on the same machine; “push” below means a push to it. From here on, commands run in <scratch>/toy.

5. The wc-3.2 brief

Role played. No coordinator delivered this brief. This session wrote it in the coordinator’s role from prompts/en/brief.md, carrying the owner’s answer and the outcome of the last landing, as step 8 of 6-landing.md says the next brief should. It keeps the epic’s id, wc-3, because wc-3.2 is still a child of it.

EPIC wc-3: branch claude/wc-3-unicode-spaces, scope wordcount check.sh README.md handoff/ runs/, grants none

This brief is for profile `backend`. If your profile is not `backend`, reply `BRIEF MISROUTED`, change nothing, and wait.

## What landed since your last epic
wc-3.1 landed on main as 9baab71 (the merge of your READY sha bc20c17). wc-3.2 waited on the owner, who answered desk card wc-3-unicode: choice `unicode-spaces`, note "Yes, and say in the README that scripts without spaces are not segmented." Your discovered item (`sh wordcount file` ignores its argument) is a separate task, not this epic.

## Why this epic
The next release promises word counts; text with non-breaking or other Unicode spaces counts wrong today.

## The epic
- wc-3.2: `sh wordcount -w` separates words on every Unicode space character (White_Space), not only ASCII blanks, in UTF-8 input.
- The README says that scripts written without spaces are not segmented.

**Acceptance:**
- `sh check.sh` passes with a test that fails without the change
- line counts are unchanged

## Scope
    wordcount check.sh README.md
    handoff/wc-3.json
    runs/*.json            (new files only)

## Grants (this epic only)
    none

## Protocol
- git fetch origin && git switch --no-track -c claude/wc-3-unicode-spaces origin/main
- push by the branch's own name, every turn
- end with `EPIC wc-3 READY <sha> <pr-url>` or `EPIC wc-3 BLOCKED <reason>`

6. The worker

From here on this session is the worker. Git runs with GIT_CONFIG_GLOBAL=/dev/null and the toy’s worker identity. Each block shows the command, its output, and its exit status in brackets.

Branch from the integration branch, without tracking it

$ git clone -q origin.git worker
[exit 0]
$ git fetch origin
[exit 0]
$ git switch --no-track -c claude/wc-3-unicode-spaces origin/main
Switched to a new branch 'claude/wc-3-unicode-spaces'
[exit 0]
$ git status -sb
## claude/wc-3-unicode-spaces
[exit 0]

## claude/wc-3-unicode-spaces with no upstream: a bare git push cannot land on main.

Reading what is there (output trimmed to wordcount and the handoff):

$ cat wordcount check.sh README.md
#!/bin/sh
# wordcount: count the lines of standard input, or with -w its words.
case ${1-} in
-w) awk '{ words += NF } END { print words + 0 }' ;;
'') awk 'END { print NR }' ;;
*) echo "usage: wordcount [-w] < file" >&2; exit 2 ;;
esac
$ jq "{status, branch, children}" handoff/wc-3.json
{
  "status": "ready",
  "branch": "claude/wc-3-count-words",
  "children": [
    { "id": "wc-3.1", "outcome": "done", "commits": ["c25fff009a37aa7cc3e776209868cc786fff6f43"] },
    { "id": "wc-3.2", "outcome": "deferred", "note": "Waits on the owner: which spaces separate words (questions[0], desk card wc-3-unicode)." }
  ]
}

(The handoff output is folded onto fewer lines here; the values are as printed.)

The handoff at working, in the first commit

$ jq -n --arg base "$(git rev-parse origin/main)" '{epic: "wc-3", profile: "backend", session: "session_<redacted>", branch: "claude/wc-3-unicode-spaces", status: "working", base: $base, children: [{id: "wc-3.2", outcome: "open"}]}' >handoff/wc-3.json
[exit 0]
$ cat handoff/wc-3.json

  "children": [
    {
      "id": "wc-3.2",
      "outcome": "open"
    }
  ]
}
[exit 0]
$ python3 <control-room>/scripts/validate-handoff handoff/wc-3.json
[exit 0]
$ git add handoff/wc-3.json
$ git commit -q -m "handoff: wc-3 working (wc-3.2)"
$ git push -q origin claude/wc-3-unicode-spaces
[exit 0]
$ git log --oneline -2
daa759d handoff: wc-3 working (wc-3.2)
9baab71 Merge wc-3: wordcount -w counts words

The session id was written as session_<redacted> in the handoff itself, not only here.

A test that fails without the change

Appended to check.sh. The spaces and letters are written as octal escapes:

# wc-3.2: every Unicode space separates words (here U+00A0, U+2003, U+3000,
# U+2028); letters outside ASCII (U+00E9, U+00E8) do not.
words=$(printf 'one\302\240two\342\200\203three\343\200\200four\342\200\250five\n' | sh wordcount -w)
[ "$words" = 5 ] || { echo "FAIL unicode spaces: got $words"; exit 1; }
words=$(printf 'caf\303\251 cr\303\250me\n' | sh wordcount -w)
[ "$words" = 2 ] || { echo "FAIL letters: got $words"; exit 1; }
lines=$(printf 'one\302\240two\nthree\n' | sh wordcount)
[ "$lines" = 2 ] || { echo "FAIL lines with unicode: got $lines"; exit 1; }
echo "ok unicode"

$ git diff --stat
 check.sh | 9 +++++++++
 1 file changed, 9 insertions(+)
[exit 0]
$ sh check.sh
ok lines
ok words
FAIL unicode spaces: got 1
[exit 1]

Red for the right reason: five words joined by Unicode spaces count as one.

The change

wordcount turns the UTF-8 encoding of every Unicode White_Space character outside ASCII into an ASCII blank, then counts fields as before. awk runs in the C locale, so the match is byte by byte whatever the user’s locale:

#!/bin/sh
# wordcount: count the lines of standard input, or with -w its words.
# Words are separated by every Unicode space in UTF-8 input (White_Space:
# U+0085, U+00A0, U+1680, U+2000-U+200A, U+2028, U+2029, U+202F, U+205F,
# U+3000), turned into ASCII blanks byte by byte, so awk runs in the C locale.
case ${1-} in
-w) LC_ALL=C awk '{
	gsub(/\302[\205\240]|\341\232\200|\342\200[\200-\212\250\251\257]|\342\201\237|\343\200\200/, " ")
	words += NF
} END { print words + 0 }' ;;
'') awk 'END { print NR }' ;;
*) echo "usage: wordcount [-w] < file" >&2; exit 2 ;;
esac

The README gains the owner’s sentence:

Words are separated by any Unicode space in UTF-8 text, not only ASCII
blanks. Scripts written without spaces between words (Chinese, Japanese,
Thai) are not segmented: each run of text between spaces counts as one word.

$ readlink -f "$(command -v awk)"
/usr/bin/mawk
[exit 0]
$ sh check.sh
ok lines
ok words
ok unicode
[exit 0]

The worker tried the same program under every awk it could find:

$ for a in mawk gawk "busybox awk" original-awk; do command -v ${a%% *} >/dev/null && printf "%s: %s\n" "$a" "$(printf "one\302\240two\342\200\203three\n" | LC_ALL=C $a "{ gsub(...); w += NF } END { print w }")"; done; true
mawk: 3
[exit 0]

(The regular expression is shortened to ... here; it is the one in wordcount.) Only mawk was installed. The result for other awks is not observed, and the handoff says so under discovered.

$ git add wordcount check.sh README.md
$ git commit -q -m "wordcount -w: every Unicode space separates words (wc-3.2)"
$ git push -q origin claude/wc-3-unicode-spaces
[exit 0]

Before READY: merge the integration branch, run the full check, record it

$ git fetch origin
[exit 0]
$ git merge --no-edit origin/main
Already up to date.
[exit 0]
$ git rev-parse HEAD origin/main
640c21c2045b27bd071882a6f3eea91f9bbe252c
9baab710c16d4e16b1ce110f86601b5b3037a2f1
[exit 0]
$ start=$(date +%s); if sh check.sh >"$SP/check.log" 2>&1; then outcome=passed; else outcome=failed; fi; seconds=$(($(date +%s) - start)); echo "$outcome in ${seconds}s"; cat "$SP/check.log"
passed in 0s
ok lines
ok words
ok unicode
[exit 0]

The run file, runs/run-wc-3-2.json, has the same shape as 3-run/runs/run-wc-3-1.json. It keeps the red output from before the change:

{
  "id": "run-wc-3-2",
  "epic": "wc-3",
  "head": "640c21c2045b27bd071882a6f3eea91f9bbe252c",

    "results": [

        "command": "sh check.sh",
        "outcome": "passed",

      }
    ]
  },
  "red_before_change": {
    "command": "sh check.sh",
    "output": "ok lines\nok words\nFAIL unicode spaces: got 1"
  }
}

[exit 0]

The last line of the worker’s turn:

EPIC wc-3 READY 56ba5091166596f17c2d882969153c119d8dcda0 https://git.example.invalid/wordcount/pull/4

Not observed: the pull request. The toy has no host, so the URL is a placeholder, like the one in 5-ready-line.txt.

8. What the lander checks

Role played. The coordinator lands, not the worker. This session ran the landing checklist of docs/protocol.md itself, in a throwaway clone with the toy’s coordinator identity, to show what each check returns. No second agent was involved.

$ git clone -q origin.git landing
[exit 0]
$ git fetch -q origin claude/wc-3-unicode-spaces
[exit 0]

  1. The branch head is the READY sha; the handoff is ready; the recorded check passed at its lane head.

    $ test "$(git rev-parse origin/claude/wc-3-unicode-spaces)" = 56ba5091166596f17c2d882969153c119d8dcda0 && echo "head is the READY sha"
head is the READY sha
$ git show 56ba509:handoff/wc-3.json | jq -c "{status, lane: .lane.head, verdict: .lane.verdict}"
{"status":"ready","lane":"640c21c2045b27bd071882a6f3eea91f9bbe252c","verdict":"passed"}
$ git show 56ba509:runs/run-wc-3-2.json | jq -c "{head, status: .gates.status}"
{"head":"640c21c2045b27bd071882a6f3eea91f9bbe252c","status":"passed"}

    Only handoff and run files changed after the lane’s head:

    $ git diff --name-only 640c21c 56ba509
handoff/wc-3.json
runs/run-wc-3-2.json

    The handoff passes the validator. The first attempt fed it through a process substitution, and the validator rejected the file’s name, since a handoff must be named for its epic. It passed once saved as handoff/wc-3.json:

    $ python3 <control-room>/scripts/validate-handoff <(git show 56ba509:handoff/wc-3.json)
/dev/fd/63: $.epic: the file is 63 but the epic is wc-3; name it wc-3.json
$ ... saved to <scratch>/v/handoff/wc-3.json ...
$ python3 <control-room>/scripts/validate-handoff <scratch>/v/handoff/wc-3.json && echo valid
valid

  2. Every changed file is inside the brief’s scope (wordcount check.sh README.md handoff/ runs/), and there were no grants:

    $ git diff --name-only origin/main...56ba509
README.md
check.sh
handoff/wc-3.json
runs/run-wc-3-2.json
wordcount
  3. Security-sensitive. Nothing: no access policy, no user text rendered, no configuration, nothing that looks like a secret. (Read by eye.)

  4. Not already landed, then merge --no-ff in the throwaway clone (the check from docs/coordinator-loop.md, for when two coordinators can land):

    $ git merge-base --is-ancestor 56ba509 origin/main && echo "already landed" || echo "not yet landed"
not yet landed
$ git merge --no-ff -q -m "Merge wc-3.2: every Unicode space separates words" 56ba509
[exit 0]

  5. The check on the merge:

    $ sh check.sh
ok lines
ok words
ok unicode
[exit 0]

  6. Push with an explicit refspec:

    $ git push -q origin HEAD:refs/heads/main && git -C ../origin.git log --oneline --graph -6 main
*   4b3e3ca Merge wc-3.2: every Unicode space separates words
|\
| * 56ba509 handoff: wc-3 ready (wc-3.2)
| * 640c21c wordcount -w: every Unicode space separates words (wc-3.2)
| * daa759d handoff: wc-3 working (wc-3.2)
|/
*   9baab71 Merge wc-3: wordcount -w counts words
|\
| * bc20c17 handoff: wc-3 ready
  7. CI. Not observed: the toy has no CI.
  8. Close and file. Not observed, because there is no tracker for the toy. By the protocol, the lander closes wc-3.2 and wc-3, citing 640c21c and run-wc-3-2, and files the discovered item (awks other than mawk unverified) as a task.

9. CR-8 itself: the check, what stopped it, and the fix

This file is CR-8’s work, on control-room’s branch claude/cr-8-e2e-transcript. Before READY, CLAUDE.md asks for a merge of origin/main and make check. The first thing the worker tried, before writing anything, was whether a new file can sit in this directory at all:

$ printf '# placeholder\n' > examples/end-to-end/transcript.md && bats -f 'replay:' tests/examples.bats
1..1
not ok 1 replay: replaying the epic gives exactly the files in the example
# (in test file tests/examples.bats, line 33)
#   `[ "$status" -eq 0 ]' failed
# Only in /tmp/bats-run-<id>/test/1/norm-end-to-end: transcript.md

tests/examples.bats compares every file in examples/end-to-end/, except README.md and replay.sh, with what a replay writes. A hand-written file beside them fails it. The brief puts the transcript exactly here, and tests/ is outside its scope, so the worker did not touch the test. The change it needs is one condition in normalized(), ! -name transcript.md beside ! -name README.md. It is proposed in the pull request under Outside scope.

That is the one real gap in control-room this run found: the replay test leaves no room for anything recorded rather than replayed, which is what issue #8 asks for.

What happened next

  1. BLOCKED. The worker pushed the transcript, opened the pull request with the proposed line, and ended its turn with:

    EPIC CR-8 BLOCKED make check fails: tests/examples.bats (outside scope) compares every file in examples/end-to-end/ with the replay, so the required transcript.md fails it; grant one condition, `! -name transcript.md` in normalized() (patch in PR #11), and it passes

    CI on the pull request failed on that test and no other.

  2. A status question. About four hours later the coordinator asked whether the worker was working or blocked. The message named the two fixes, but it called itself “a status question (not a brief)”. The worker’s protocol answers a question and changes nothing, so the worker answered “blocked”, said what brief would unblock it, and did not commit.

  3. A pause. The coordinator then paused all work on this repository. The worker’s tree was clean and already pushed. It replied with one line and waited:

    PAUSED CR-8 99ca68c676743ee4011a2b54670a81227cd3ed7c

  4. The grant. The RESUME message repeated this brief, and it told the worker to “fix the red check”: “Either exclude it from that comparison (and say why in the test) or move it out of the compared tree”. The brief fixes the transcript’s path, so the worker excluded the file and wrote the reason into the test:

    $ bats -f 'replay:' tests/examples.bats
not ok 1 replay: replaying the epic gives exactly the files in the example
# Only in /tmp/bats-run-<id>/test/1/norm-end-to-end: transcript.md
$ # add `! -name transcript.md` to normalized(), and the comment
$ bats -f 'replay:' tests/examples.bats
ok 1 replay: replaying the epic gives exactly the files in the example

The result of make check on the final branch, and CR-8’s last line, are in the pull request. A file cannot hold the sha of the commit that contains it.
