The "two Monaco editors sharing a model" elimination asked which OTHER
component mounts Monaco and never asked whether the code editor collides with
itself. It does — the panel is addable to a dashboard twice, and useEditorState
keeps files in a plain useState, so two panels hold two independent buffers for
one globally-keyed model.
Verified against @monaco-editor/react@4.7.0's built source rather than inferred.
Model lookup is getModel(uri) || createModel(value), so the second mount adopts
the first panel's buffer and ignores its own freshly-read value. The value-sync
effect then overwrites the shared model with executeEdits. And the flag that
suppresses onChange during that write is per-instance, so one panel's
programmatic write fires the OTHER panel's onChange — which CodeEditor answers
with setContent(path, value). The other panel's buffer becomes this one's
content and goes dirty with no keystroke: dirty tab, content nobody typed, disk
untouched, fixed by reopening. Exactly the reported shape.
Unmount also disposes the shared model (keepCurrentModel defaults false), and
key={activeFile.path} means that fires on every tab switch, not only on panel
close — so one panel can dispose a model another is still displaying.
Not yet a closed case: nothing in the app writes job output into
useEditorState, so this produces the right shape but does not explain where the
log text comes from. No fix shipped — the two candidates (per-panel model URIs
vs sharing the state to match the shared model) differ in whether Monaco's
TypeScript resolution keeps working, and that is the owner's call. Trap stays
armed.

todo/ — the format
One item per file. A file is a card. That is the whole idea, and everything below follows from it.
It replaced a single 1,050-line TODO.md on 2026-08-21, which had reached 72 open items across 28
sections and was read mostly on a phone. The split was mechanical — no prose was rewritten.
Layout
todo/
├── README.md # this file
├── <theme>/
│ ├── _index.md # the theme itself: display name, and any prose that belongs to the whole group
│ └── <item>.md # one item
The theme is the directory. _index.md carries the theme's display heading, so a theme is
self-describing and nothing has to hold a slug→name map. TODO.md at the repository root is the
generated index over all of it — bun run todo:index.
An item
---
id: fleet/an-orchestrator-that-acts-on-every-server-at
title: 'An orchestrator that acts on every server at once'
theme: fleet
status: open

date_source: stated
order: 1

**An orchestrator that acts on every server at once** — pull and update every platform, restart a
process everywhere, report which host is behind…
id—<theme>/<slug>, and it is the filename. Stable: rename the title freely, leave the id alone. Anything pointing at an item points at this.status—open,doing,blocked,backburnerordone. The board (/todos) renders one column per value; adding one is a new entry inTODO_STATUSES(api/todos/todo-tree.ts), not a new file or directory.backburneris parked-not-dead — still counted as open by the index.created— the date the item was raised.date_sourcesays how much to trust it:stated(the prose named a date — true),section(inherited from its old section heading — close),assumed(unknown, floored at 2026-08-20, the day before the split — a bounded "before today" rather than an invented day).order— position within the theme, preserved from the original list. What a board reorders.priority(optional) —urgentwhen the owner says so, absent otherwise. There is no scale of five: an item is either something he named as urgent or it is not, and a scale would only invite everything to drift upward. Urgent items are listed first in the generated index.due(optional) — a date the owner named. Only ever written because he said one; never inferred from tone or from how the item is worded.- The body is prose, and it is the point. These entries carry the reasoning, what was verified versus assumed, and what was already tried. An item stripped to a title loses the thing that made this list worth keeping.
Two-way sync — the contract for the Kanban board
A board that reads this tree and writes back to it is a wanted feature
(todo/prompt-library/… see todo/tooling/). What it may rely on:
- A card is a file. Creating a card creates a file; moving a card between columns rewrites one frontmatter field; deleting a card deletes a file. Every board action is a small, reviewable git diff.
idis the identity, not the title and not the line number. Renaming or rewording never orphans a card.- Frontmatter is the machine's half, the body is the human's half. A board may rewrite frontmatter freely. It must not reformat a body it did not change — the prose is hand-written and a normalising pass would produce a diff nobody can read.
TODO.mdis generated output. A board must never write to it; it regenerates from the tree.- Git is the sync log. No lock file and no sidecar state: the file on disk is the truth, and two writers are resolved the way every other conflict in this repository is.
