clawbot 3e36c966ba Keep what was typed when a target or webhook edit is refused (closes #381)
check / check (push) Waiting to run
Details 
A refused save on the target edit page now shows the edit form again,
with the reason above it and every value submitted, instead of a bare
text page; the status codes are unchanged. The webhook edit page keeps
the submitted name, description and retention the same way, while the
page still reports the stored retention.

Target edits are validated by setTargetFromForm, which newTarget now
uses too, so the add and edit forms accept and refuse the same things.
An empty max_retries keeps the target's own count.

The browser test also saves both edit pages with refused values.

`static/css/tailwind.css` is generated by Tailwind and committed. To change the
styles, edit the templates, `static/js/app.js`,
`internal/handlers/recent_events.go` or `static/css/input.css`, run `make css`,
and commit the regenerated file with the change. Tailwind takes classes only
from the files that `input.css` names in its `@source` lines; a class written in
any other file is not generated until that file is named there too. `make check`
and the image build fail when the committed file differs from what `make css`
generates. `static/css/style.css` is hand-written and is not generated.
`make css` runs the Tailwind standalone CLI in Docker, at the version and sha256
pinned in the Dockerfile's stylesheet stages; it is never installed on the host.

when nothing is left. The target UUID keeps the file name unique. A
webhook named `Orders (EU)` with a target named `Long-term archive`
archives into `archive-orders-eu-long-term-archive-{target_uuid}.db`.
An optional `rotation` in the target's config JSON (e.g.
`{"rotation":"daily"}`) is `none`, the default, which keeps the one
file, or `monthly`, `daily` or `hourly`. A target that rotates writes
each event to a file named for the period of the event's receive time,
in UTC, put before the `.db`:
`archive-orders-eu-long-term-archive-{target_uuid}-2026-10.db` monthly,
`…-2026-10-01.db` daily and `…-2026-10-01-19.db` hourly. Each file holds
exactly its period's events, and the first event of a new period starts
the next file, so a finished period's file can be moved away like any
archive. A changed rotation applies from the next event: the files
already written keep their names and stay, pruned, shown and downloaded
with the rest, since every file named for the target is its archive,
whichever rotation wrote it.
Renaming the webhook or the target renames every one of the target's
files, each keeping its period, under the same lock the archive writes
and the archive sweeper take. Webhook edits, target edits and target
creation run one at a time, so no edit can rename the files between
another's rename and save, and the names on disk match the UI. A rename
never replaces a file: if one already has a new name, the edit is
refused with an error naming that file, nothing is moved, and the
stored name stays. If the archive is not there (the operator moved it
away), the rename is not an error, and the next write creates the file
under the new name.

For a target with several files, the write path prunes only the file it
writes to, and the sweep prunes every one of them, taking the target's
lock for one file at a time, so a write to the target waits for at most
one file's prune. A file that is gone by the time the sweep reaches it

deleted, with any `-wal` and `-shm` beside it; the file without a period

Because each `database` target has its own archive file, a target's
`expiry` governs only its own archive. Two `database` targets on one
webhook with different expiries keep two archives, each pruned on its
own schedule.
The webhook page shows, for each `database` target, the name of the
archive file an event received now would go to, the size on disk of all
the target's archive files together, how many there are when there is
more than one, and when the latest of them was last written. The size
counts each `.db` and its `-wal` together, and the last write is the
latest of their modification times, since a write lands in the `-wal`

`script/lint` builds after `Dockerfile.lint` and the image build runs
before the builder stage. Its version is pinned in `package.json` and
every package's hash in `yarn.lock`. The `js-deps` stage before it
installs ESLint and stays cached until either file changes, so only the
lint step re-runs and ESLint is not downloaded again.
`eslint.config.mjs` turns on the rules of the JavaScript styleguide
`REPO_POLICIES.md` links to that a linter can check: `no-var` and
`prefer-const`. ESLint prints nothing on a pass, so `script/lint` has no
summary line to look for; it names the stage once for both `--target`
and `--no-cache-filter`, and `--target` fails on a name that matches no

The Dockerfile uses a three-stage build. Each stage is pinned by
digest, and the two check stages are separate images so the linter's
version is fixed independently of the compiler's:
1. **Lint stage** (`golangci/golangci-lint:v2.12.2`, Debian-based) —
installs `make`, downloads dependencies, copies the source, and runs
`make fmt-check`, then `script/assets` to extract Alpine.js from
`3p/`, then `golangci-lint config verify` and `golangci-lint run`,
both with `--network=none`.
2. **Stylesheet stages** (`debian:bookworm-slim`, with the Tailwind
standalone CLI pinned by version and sha256, one binary per
architecture) — generate `static/css/tailwind.css` from
`static/css/input.css` and the files its `@source` lines name.
`css-check` fails when the committed file differs from the generated
one, and `make css` writes the generated file out from `css-output`
(see [Stylesheet](#stylesheet)).
3. **JavaScript lint stages** (`node:24.21.0-alpine`, with yarn) —
`js-deps` installs ESLint from `yarn.lock` and `js-lint` runs it over
`static/js/` (see [Linting](#linting)).
4. **Builder stage** (`golang:1.26.1-bookworm`) — depends on the lint,

each), runs
