Ledger

Read-only counts from local refactor commit subjects, one Gitea issue-list request through scripts/gitea-api.sh, repo seats' Pi session logs, and T3's thread messages in ~/.t3/userdata/state.sqlite. Above the counts, a queue section checks docs/plans/queue.json against Gitea and the seat registrations (see "Queue section"). No board changes, data-root writes, fleet reads, transcript output, or scheduler.

Dates include both endpoints in UTC. Omitted --until means today in UTC. The checkout containing this package supplies the sources, not the shell's cwd. No install, build, service restart, or configuration change is needed.

Counting rules

• Git uses committer timestamps and every commit reachable from local refactor, including merges. It reads subjects only. A repeated #N in one subject counts once. A commit naming two issues counts for both rows but once in total commits. Untagged commits do not count. Issue numbers are literal references to mosaicstack/stack, with no attempt to remap archived repositories' numbers. This can associate historical references with unrelated same-number issues.
• Table 1 includes issues with a tagged commit or a closed_at in range. Opened is created_at; hours open is closed_at - created_at, rounded to one decimal, or open if not closed. It is not age as of --until. Reopen history is unavailable from the issue-list response. Median hours open uses only issues closed in range and rounds after computing the median.
• Follow-ups are max(commits in range - 1, 0) per issue, not a lifetime count and not a quality assessment. Follow-ups per issue divides their sum by all Table 1 rows, including close-only rows.
• Table 2 counts user-message entries in .pi/state/<seat>/sessions/*.jsonl where <seat> is a real directory in agents/. All matching files count; duplicated entries in copied logs are not deduplicated. No transcript content leaves the parser. Assistant messages and logs outside repo seats do not count. Symlink source directories are refused and symlink files are not followed. A line ends at \n only. A U+2028 or U+2029 inside a JSON string does not split a record.
• Table 2 also counts T3 thread messages with role user. The T3 source follows. A seat's row sums its Pi and T3 counts; the JSON keeps the split in pi (Pi rows) and t3.seats (T3 rows).
• The first text line alone classifies a message. Two addressing forms count: the tmux preamble [host:session -> host:session] that agent-send.sh writes, and the T3 header [from: role (thread-id) -> to: role (thread-id)] from docs/guides/T3-AGENT-COMMS.md. Either may carry class=<class> before the closing bracket. A preamble whose sender is control-board (tmux session or T3 role) is board; any other valid preamble is agent; otherwise human. The class may be in either case: seats send class=DECISION. This is a format count, not proof of who typed the message. Text blocks are joined with newlines. The entry timestamp is used, falling back to the message timestamp.
• Seats with no in-range user messages are omitted. Issue seats come from #N mentions anywhere in in-range user text, including quoted text.
• Human messages per closed issue divides Table 2's human sum by issues closed in range. A zero denominator with human messages is unknown; a truly empty report has zero totals. JSON keeps numeric values as numbers; text displays ratios and durations with one decimal. Titles truncate to 48 characters in text only. Missing evidence is the literal string unknown.

T3 source

The rules come from docs/plans/2026-09-26_ledger-t3-source.md (Gate F). The source is on by default. --no-t3 skips it, and the report then says T3: not read (--no-t3). --t3-db <path> reads another database file with the same checks. The JSON records the database path and whether it was the default. When it wasn't, the text report prints the path, so a fixture result can't pass for a live one. The two flags can't be combined.

The reader opens state.sqlite read-only through node:sqlite and reads no other file in ~/.t3. It runs every query in one read transaction with a 5 s busy timeout. It never writes the main database file. Like any SQLite connection it may create -wal and -shm beside it, so a directory that isn't writable refuses when SQLite needs them.

• Project. Only threads in the one non-deleted T3 project whose workspace_root equals this checkout's root byte for byte. The root is the realpath of the package, so a project opened through the compatibility symlink ~/src/mosaic-stack-dev-test does not match, and the report refuses with no project.
• Thread to seat. A thread belongs to seat <s> when <s> is a real directory in agents/ and the lower-cased title equals <s> or starts with <s> and a space. "Dewey in Claude" maps to dewey; "Sagebrush" maps to nothing. Several threads can map to one seat. Threads that map to no seat share one row, t3:unmapped, so their human messages still reach the totals. t3.seats and t3.unmapped in the JSON list the thread ids and titles behind each row.
• Titles are current state. T3 titles an unnamed thread from its first prompt, and a rename moves a thread's whole history to another row. This moves counts between rows, never out of the totals.
• Header check. A user message whose T3 header is addressed to its own thread id must name that thread's seat as the to: role (compared lower case). In an unmapped thread the to: role must not be a seat. A conflict exits 1 and names the thread, its title and both roles. A header addressed to another thread isn't checked. The check misses a renamed thread that no agent writes to. Such a thread can only add human counts to a row.
• Excluded. Imported threads (id prefix import:) are partial copies of Claude Code sessions, not T3 traffic; every T3 event marked historyImport sits in one today. Deleted threads don't count; archived threads do. t3.excluded gives both thread counts.
• Blind spot. Threads in other T3 projects are not counted, even if they worked on this repository. Live, there is a project at /home/jwoltje and a deleted one at /mnt/storage/src.
• Diagnostic. t3.diagnostic.humanSentThroughApi counts in-range user messages the header rule calls human that T3 recorded as sent through its API (no appVersion in the event's origin). Those are seat messages whose header the rule doesn't accept, such as the older free-text Discord Bot headers, and would show the next format drift. humanWithoutEvent counts human messages with no thread.message-sent event. This is T3's internal metadata, so it feeds no table or total. If orchestration_events or a column it needs is missing, or an event doesn't parse, both read unknown.

These refuse the report with exit 1, and the ones about the database name --no-t3: a missing, unreadable or unopenable database (including a busy lock past the timeout); a symlink at ~/.t3, ~/.t3/userdata or state.sqlite (with --t3-db, the file or its directory); a missing table or column the counts need; no project or more than one for this root; a message in a counted thread with a role other than user or assistant, non-text content, or a created_at that doesn't parse; a header conflict. A missing Pi directory means no Pi seats ran here; a missing T3 database means the path or T3 changed, so it refuses instead of counting zero. Error messages name ids and paths, never message text.

Queue section

The rules come from plan 8.10 in agents/filbert/work/queue-as-data-plan-2026-09-26.md (Piece E, #1508). The section is on by default and prints above the weekly table; --json puts it under queue. --no-queue skips it and prints Queue: not checked (--no-queue). The ledger reads docs/plans/queue.json through the queue's own validator before any Gitea call, so a missing, symlinked or hand-edited file exits 1 and costs no call. It writes nothing, takes no queue lock and never changes a row.

Four checks, each finding named by (check, row, issue):

• Issues. An issue is expected closed once every row whose closes includes it is done (J6). Then an open issue is issue-open on each of those rows. A row that names an issue in issues but not in closes is never checked against it, so rows 9 to 12 can be done while #1508 is open. A closed issue with a row that closes it still pending is printed as a disposition for the lead. It is not a violation.
• Owners. Each owner of an in-progress or in-review row gets one liveness class from its repo registration in <dataRoot>/seats:
  • exempt: declared on this run with --unsupported-runtime SEAT.
  • missing: no registration, or one written for another checkout.
  • invalid: the registration fails validation, or the config that names the data root can't be read. A malformed or absent pid fails validation, so it lands here, not in pid-unknown.
  • pid-unknown: a valid registration with a null pid.
  • pid-gone: the recorded pid is not running.
  • pid-present: the pid is running. A registration holds no process-start identity and a reused pid looks the same, so this reads "pid present (identity not verified)". The coverage line counts them: liveness: N pid-present (unverified), N exempt, N pid-unknown, N missing, N invalid, N pid-gone.
• Age. A required row that is not done and whose requiredSince is more than 14 whole days before the run is listed by name. requiredSince is a date at genesis and an ISO time once set required or add --required writes it; both count from 00:00Z of their UTC day. A value that doesn't parse as a date is an age-invalid violation. A legacy row with requiredSince: "unknown" was required no later than genesis, so once genesis is more than 14 days old it is listed as age ≥ N days (legacy lower bound). Before that its age is undecided. Age runs to the time of the run, not to --until.
• Protected changes. Every log entry dated inside the report range that changes a required or parked row is listed with its revision, verb, claimed actor and rows. The queue trusts --by (its README, "Trust boundary"), so this list is how a wrong claim gets seen. It is not a check and never changes the result. Jason confirms the actors weekly.

Every run ends with queue: N violations; result R, where R is one of three:

• fail: any violation. That is an open issue, a missing, invalid or pid-gone owner, or an age.
• incomplete: no violation, but something undecided. That is an issue whose state is unknown, a full open-issue page with some issue left unknown, issue checks not run, a pid-unknown owner, or a legacy age before genesis is 14 days old.
• reduced pass: nothing known and nothing undecided. There is no full pass, because no owner's process identity is ever verified.

The exit code stays 0 whenever a report was computed; the result is in the text and the JSON.

Queue issue calls

The metric call can't answer "is this issue closed", because an issue nobody touched this week isn't in it. So the queue checks have their own budget, per plan 8.10:

Calls	Purpose
1	state=open, issues only, limit 50, one page. A full page may be short. Issues missing from it are looked up, so it makes the run incomplete only while some issue a row closes has no known state (lead decision 40).
up to 10	GET issues/N for each issue in some row's closes that is neither on the open list nor closed on the metric page. Beyond 10, the issue's state is unknown, "over the lookup budget".

With the metric call that is at most 12 calls. --no-issues makes none and prints queue issue checks: not run. Closed needs positive evidence: an entry on the metric page with state closed and a closed_at, or a lookup returning a closed issue that isn't a pull request. A failed lookup, a 404, a pull request or a mismatched number leaves the issue unknown. A failed or malformed open-list call exits 2, like the metric call. Each queue call runs under timeout -s KILL 60, which kills the helper and its curl together.

Weekly routine

Run the ledger each Monday for the week that ended on Saturday, Sunday through Saturday as row 7 counts it, with the queue section on and no --no-issues:

node packages/ledger/src/cli.mjs --since 2026-09-20 --until 2026-09-26

Post the dated run on #1508 with its coverage line and result. Any seat whose runtime writes no registration (T3 seats today) is passed with --unsupported-runtime SEAT, which the output prints. A violation is remediated when a second dated run on the same UTC day no longer reports its (check, row, issue), and both runs are posted on #1508. A row edit alone is not remediation, and a note can't clear an owner finding, because that check reads registrations. Row 13's gate is one Monday run with zero violations, or every violation remediated that day.

Gitea calls and missing evidence

The metric client requests issues updated since the start date, all states, first page, limit 50. This includes issues closed in range, even if later updated. Gitea caps responses at 50; a full page fails rather than silently reporting partial totals. Use a narrower range or --no-issues, not hidden pagination. A commit-linked issue not returned by the updated-since query still has a row, with unknown metadata. This is the cost of the brief's one-call boundary.

Exit 0 means a report was computed. Exit 1 means bad arguments, a queue.json the validator refuses, or unreadable git, session or T3 evidence. Malformed JSONL, including a partially written last line, refuses the report; rerun after the seat finishes writing. Exit 2 means issue credentials, API, payload, or completeness failure. The CLI never prints API error bodies or reads authentication files itself. The queue's open-list call fails with exit 2 the same way. --no-issues makes no API call, keeps commit-derived rows, and shows unknown issue metadata, closed counts, median duration, and human-per-closed ratio. It cannot invent close-only rows.

For fixtures, a fake gitea-api.sh can be placed first on PATH. Otherwise the repository scripts directory is appended to PATH for the issue request. Tests use only temporary repositories, logs, T3 databases, queue files, seat registrations, configs and fake API tools, with no real credentials or network. Every CLI run in the tests sets HOME to a temporary directory, so no test opens the real ~/.t3. The helper regression stubs Node before any credential read and checks successful GET, successful POST, and failed HTTP status.

Acceptance

Gate D is Jason's: run the requested week, choose a number to move next week, and write the sentence and number into docs/plans/CURRENT.md. Automated tests and publication do not pass that gate. Remove the package to stop using it; there is no persistent ledger state to migrate or restore.
