The Weather panel kept a second time transport of its own: a slider, step buttons, Latest and Play, backed by a replay in the weather clock that stepped the observed frames every two seconds and went round from the last to the first. The weather clock also attached itself to the world clock as a driver, so the timeline's Play became that replay whenever weather was on. The panel now shows the frame time only: the newest frame and its age while live, the timeline time alone at a past time. The weather clock no longer has setTarget, step, latest, play, pause or togglePlay, its state no longer has playing, and it no longer drives the world clock. It still follows the world time, registers each product's frames as marks the timeline's arrow keys step to, holds its products, and gates the world's continuous play at each next frame until it loads. weatherClock.world names the world clock it follows. A weather row's play, latest and step params move the world clock as the timeline does: play toggles continuous play (from the start of the covered time when live), latest goes live, and step goes to the previous or next mark. The rail timeline component, which only the panel used, is removed, along with its unused messages in every locale.
Changelog fragments
One file per entry. A pull request adds a file here instead of editing
CHANGELOG.md, and a release concatenates them into it.
changelog.d/<pull request number>-<slug>.md
723-atc-decision-layer.md, for example. The slug is lowercase, words separated
by -. Two pull requests never pick the same filename, because the pull request
number is already unique — which is the point: new CHANGELOG.md entries go at
the top of the file, so two pull requests in flight write into the same few lines
and git has nothing to merge on.
Write the file exactly as the entry should read in CHANGELOG.md: a - bullet,
wrapped the way the surrounding entries are, crediting yourself and the pull
request.
- Report which upstream declined a Street Traffic road load. The layer row now
reads `Overpass rate-limited` instead of a general "Road data temporarily
unavailable" (yourname, #665).
The text is spliced in unchanged apart from trailing whitespace, so what you
write here is what ships. Fragments are deliberately outside
scripts/format-scope.json, so npm run format never reflows one.
At release time:
npm run changelog:check # list what would move, change nothing
npm run changelog # move every fragment into CHANGELOG.md
The assembler refuses a batch rather than guessing: a filename that is not
<pull request>-<slug>.md, or two fragments claiming one pull request number,
stops the run before anything is written and names the files.
If npm run changelog fails part-way (a full disk, a killed process), run it
again. The batch is staged in changelog.d/.assembling/ and only lands when the
assembled file replaces CHANGELOG.md in a single rename, so the rerun either
finishes that batch or puts its fragments back first. It never adds an entry
twice or drops one. npm run changelog:check names a staged batch, if one is
left over, instead of reporting past it.
A documentation claim that needs a regression test — the way
src/annotations/drawTool.test.mjs asserts against CHANGELOG.md — should
assert against docs/CURRENT-STATE.md or README.md instead. A pull request
still edits those directly, so the text is in the file while the change is under
review; a fragment does not reach CHANGELOG.md until release.
