One item, one day. A forwarded email lands at 08:05. By the next night it is a dated project on the board with its own deadline on the calendar, and no part of the message was ever executed or allowed to touch anything another person can see. The rail is the day's schedule as it actually runs; the gold stops are the ones the item passes through. Open any stop to see what that surface showed.
14 stops · 9 on the item's path · 19 surfaces · four kinds of edge:
Whatever the day left in the working tree is committed as state, and a journal stub for the new day is created with its headings empty.

The editor that writes the morning paper runs as a model call with every tool denied. It reads yesterday's feed captures and newsletters, which are untrusted, plus the board and the decision queue, and it can emit one JSON document and nothing else. Plain code renders the page from that.

editor: tool-less · 41 s · schema ok · links stripped: 9 · fields rejected: 0David forwards a residency call from one of his own addresses to the sandbox mailbox. He adds no prefix. Since September an unprefixed forward from his own address counts as "read this", because a third of what he sent in the first weeks was dropped for want of one.

Once an hour a script checks the inbox, read-only, with regular expressions and no model. It copies the whole forward into a quarantine file that no surface renders. A second lane then makes one model call with no tools, reading only that file; it can return JSON text and nothing else. Plain code re-words a card in the decision queue from the JSON. The card's buttons come from a fixed list per kind; whatever the model suggested is printed as text beside them.

Every ten minutes a set of small checks reads state, logs and the calendar cache. Each writes a line. The pager that sits behind them fires on change, not on state: an alert that was true at 09:00 and is still true at 09:10 is not sent twice. When that rule went in, sixty-six replayed pages became six.
[NOTICE] flightpath-drift: due in 7d: tessellate-prize 2026-10-09
pager: no change since 09:00 · nothing sentA session opens and the first thing printed is the seven-line brief, derived from the board and the queue by the same code that feeds the phone page, so every surface quotes the same text. Line 6 counts one inbound card. The assistant raises it with the fence visible and asks. David rules in his own words.

The ruling becomes state through the one validating command-line tool that is allowed to write it. A new project; its due, typed external because someone else set the date; its materials milestones, letters first, with a start date of due minus 21 days; the apply note carrying the card's id; a next. Each is an event in an append-only log with the reason that went with it. Four renders rebuild from the state file. One calendar event is upserted on a calendar only David reads.

Nobody edits these. They are re-rendered from the state file, so they cannot disagree with it or with each other.

The next tick sees a due that was not there at 09:40. A new due is a change, so the pager looks at it. A date forty-nine days out is a condition, not an event, so it waits.
[NOTICE] flightpath-drift: new due: saltmarsh-2027 2026-11-20 (49d)
pager: condition, not event · logged, not sentA midday reader looks at the board against the day's calendar and nudges only when a date is about to pass with nothing logged. It writes a note on a project only when it changes an expectation. Today it has nothing to change.

Code changes, including anything a timer will run, never land on the main branch from a session. A builder works in its own worktree and stops at the PR body. A preflight checks for base drift and for open PRs on the same files. The session opens the PR. Merging is David's click, on the app, as a merge commit.

A scheduled check reads every repository's status and prints one strip: dirty files, unpushed commits, held changes, a live checkout behind its upstream, feeds that have gone quiet. It fixes none of it. The strip is what the next session reads first.
PATROL: dirty — projects 6 • unpushed 0 • held 1 • BEHIND upstream: none • flightpath 5 writes/24h • feeds: all answered
Closing a session takes a lock first, because two closes at once tear the journal. A second session waits and is told who holds it; a holder that has gone silent is stolen, and the steal is logged. Then wrapcheck lists any project that got a note today without its next being rewritten, which is the usual way a plan rots. The journal gets five bullets at most. A session span lands on a calendar only David reads.

The state file and its log are committed. Every mutation of the day can be replayed from the event log and from git, each with the reason that was written beside it.
