clawbot d453f76fb3 Keep each model's parent out of its JSON (closes #177)
check / check (push) Waiting to run
Details 
Every reference from a model to the record it belongs to is now
json:"-", so the webhook and target models (and the other parent and
child pairs in internal/database) can no longer marshal each other in
a loop. Preloading maps associations without reading json tags, so it
still fills these references; a new test preloads a webhook with its targets and
entrypoints and a target with its webhook, checks the references are
filled, and checks the marshalled JSON leaves them out.

clawbot b14b27b78b Serve the delivery duration histogram from boot (closes #267)
check / check (push) Waiting to run
Details 
The delivery duration histogram was registered only when a delivery first ran, so until then /metrics had no series for it and a dashboard or alert on it saw nothing at all rather than zero. Each of the four target types now has its series registered at boot with zero counts, so the histogram is served from the first scrape. Tests pin that all four series are present before any delivery, on the metrics registry and through the production router.

clawbot 287e47df7f Add a read-only Settings page for the loaded configuration (closes #402)
check / check (push) Waiting to run
Details 
A new page at /settings, linked from the navigation bar and behind the login, lists every configuration field the server loaded at startup: its environment variable, the README table's description, and the value in effect. METRICS_PASSWORD and SENTRY_DSN show only as set or not set; their values are replaced before rendering and never reach the template. The route is GET only and its group is built like the other admin page groups. Tests set the credentials one at a time so each value shown is checked against its own field and a set secret never appears in the page.

clawbot 8b5541734e Run script/test quietly with coverage, rerun failed tests verbosely (closes #315)
check / check (push) Waiting to run
Details 
script/test now runs the suite once with -race -cover and no -v. On a failure it reruns only the failed top-level tests, with -v, in the packages that failed, then exits non-zero whatever the rerun shows. A green run stays quiet, and a red one ends with the failing tests' verbose output, which the Docker build's 2 MiB log limit can hold; a verbose rerun of every package would pass that limit again. A failure that names no test (a build error, a timeout) skips the rerun, since the quiet run already prints that package's output. The timeout and parallelism are unchanged.

clawbot c513816a55 Refuse [::], 0.0.0.0, IPv6 multicast and documentation space (closes #341)
check / check (push) Waiting to run
Details 
On the build host a connection to [::] reaches a listener on ::1, and one to 0.0.0.0 reaches 127.0.0.1, so a delivery target at either reached this host's loopback past the guard. 0.0.0.0/32 and ::/128 are now in alwaysBlockedNetworks, which no allowlist opens; an allowlist reaches loopback only through an entry covering a loopback address. IPv6 multicast (ff00::/8) and documentation space (2001:db8::/32) are refused by default and reopen when listed.

Every default blocklist entry has a one-line comment, each list is pinned on its own, and tests refuse each address at target creation and at delivery. The README and the rules above each list match.

clawbot 2bb4683512 Discard fx's own log in tests that build an fx app (closes #230)
check / check (push) Waiting to run
Details 
Every test that builds an fx app with fxtest.New (handlers, server, resetpw, gormlog, config) now passes fx.NopLogger, so fx's own log no longer goes to t.Logf. A hook still running after a start or stop timeout can then no longer write to a test that has already returned, which the race detector reported as a data race. What the tests assert is unchanged, and nothing about the race detector is suppressed.

clawbot 5b1d283d06 Say what each action did in a one-line notice (closes #383)
check / check (push) Waiting to run
Details 
Saving, deleting, activating or deactivating a webhook, entrypoint or target, and signing out, now land on their page with a one-line notice such as "Webhook deleted." or "Signed out.". The redirect carries a fixed code that maps to fixed text; an unknown code shows nothing, so nothing from the URL is ever echoed. One partial in the page layout shows the notice on every page, and replay and resubmit now use the same codes and partial. Error pages show no notice.

clawbot b78abdc9da Drop TODO.md's stale docs-only cache caveat (closes #421)
check / check (push) Waiting to run
Details 
Since the build context carries .git and the CI fingerprint is the hash of the commit being checked, every commit's check runs the build, docs-only commits included. TODO.md's caveat that a docs-only commit replays from the layer cache was no longer true, and the README's "CI gate honesty" section already says how a check runs, so the paragraph is removed.

clawbot c23ffbac65 Widen the webhook page by half so an entrypoint URL fits on one line (closes #350)
check / check (push) Waiting to run
Details 
The webhook page's maximum width goes from 72rem (1152 px) to 108rem (1728 px), half again as wide, so an entrypoint URL stays on one line in 1920- and 1440-pixel windows; the statistics pane and both columns widen with it. The title row now wraps, so a phone-width window no longer scrolls sideways.

The width is an inline style: static/css/style.css is linked by no page, and the committed Tailwind stylesheet has no class that wide. The webhook list, the event log, the navbar and the footer stay at 72rem.

clawbot 2ac4d4d793 Send the build version in the outbound User-Agent (closes #313)
check / check (push) Waiting to run
Details 
The http and slack targets sent the constant User-Agent webhooker/1.0. They now send webhooker/ followed by the version the build stamped, the same value the footer shows, built in one place on the delivery engine. User-Agent stays a reserved header and is still set after the target's configured headers, so a configured one cannot override it. Tests check the header each target sends against a known version, and that a configured User-Agent is replaced.

clawbot eb4c4cc849 Serve /metrics from a registry of its own (closes #227)
check / check (push) Waiting to run
Details 
A second metrics-enabled router in one process panicked on a duplicate collector registration, because every collector registered on Prometheus's global default registry. metrics.NewRegistry now builds one registry with the Go runtime and process collectors; fx provides it and the delivery metric set built on it. The middleware builds its HTTP recorder once on that registry (NewForTest on a fresh one), the engine and handlers take the metric set from fx, and nothing registers on the global default any more.

/metrics is served from the new registry with the same series names, labels and auth. A test builds two metrics-enabled routers in one process.

clawbot cb7bafab17 Derive the image's version from the .git in the build context (closes #366)
check / check (push) Waiting to run
Details 
upaas uploads its clone as a tar context, which .dockerignore does not filter, so its builds already carried .git; the unknown default of the VERSION build arg is what stamped them. The image now derives its version itself: ARG VERSION has no default, so make build falls back to script/version, which runs git describe on the copied .git; a VERSION build arg still wins.

.dockerignore sends .git without its config in a directory context and no longer leaves out tracked files, which would mark the tree -dirty. The builder installs git, trusts /build as a safe.directory, and fails when .git is present but the version comes out unknown. A shallow single-branch clone stamps its short commit.

clawbot 2416528b77 Render admin page errors in the normal layout (closes #382)
check / check (push) Waiting to run
Details 
Every 400, 403, 404 and 500 on an admin page now answers with an error page in the normal layout: the status, one fixed line explaining it, and a link back to the webhook list, or to sign-in when nobody is signed in. Unknown paths reach it through the router's not-found handler, a refused form token through the CSRF middleware, and a panic through a recoverer each admin page route group installs first. Status codes are unchanged, and the page always sends Cache-Control: no-store.

If the error page fails to render, the answer is the same status in plain text; if it panics, the answer is a 500. The receiver, the healthcheck and /metrics keep their plain answers.

clawbot 38157d8936 Say how to allow a refused private target address (closes #398)
check / check (push) Waiting to run
Details 
Refusing an http or slack target whose address is private or reserved, on add or edit, now adds one sentence: such addresses are refused by default, and the server's ALLOWED_EGRESS_CIDRS setting allows named networks, with a pointer to the README section. It suggests no value, so it never points at allowing everything.

Metadata refusals get no such sentence. To tell them apart, the default blocklist's public addresses now have their own list, blockedPublicNetworks, still checked after the allowlist; a test pins which addresses each list refuses and how listing opens them, unchanged from before.

clawbot 7d360babed Logging in returns to the page that was asked for (closes #384)
check / check (push) Waiting to run
Details 
A logged-out GET of an admin page now redirects to /pages/login with its path and query in a next parameter, when they fit in 2048 bytes. The login form carries next as a hidden field; a successful login redirects there, and a failed one shows the page again with the same next. A POST still redirects to plain /pages/login.

The value is client-chosen, so every read of it goes through one check: after percent-decoding it must start with exactly one / and contain no backslash or control character; anything else becomes /. gosec's open-redirect rule is suppressed on the two redirects that follow it. The login page's navigation bar no longer links to itself.

clawbot 803a94be37 Add a statistics pane to the webhook page (closes #368)
check / check (push) Waiting to run
Details 
The webhook page opens with a statistics pane: entrypoints and targets, deliveries in progress, the last arrival, the retention period; events, deliveries and failures, lifetime and within retention; and events, failures and failure percentage over 10 minutes and 24 hours.

Running totals, one row per target plus one for events, sit in each webhook's event database and are written in the same transaction as the rows they count; retention prunes in paused, stoppable batches and subtracts what it removes. Window figures are index-range counts on a new finished_at column. An existing event database must be recreated.

clawbot 43ed8d4834 Move webhook pages to /hook/ID and inbound URLs to /h/UUID (closes #367)
check / check (push) Waiting to run
Details 
The webhook page and everything under it move from /source/ID to /hook/ID; the list and new-webhook form from /sources to /hooks and /hooks/new; the event log from .../logs to /hook/ID/events; entrypoint URLs, the ones senders post to, from /webhook/UUID to /h/UUID. The old paths are simply gone, per the owner's ruling. Every link, redirect, form action, test, comment and README mention follows; every link to the event log, and its title and heading, read "Full Event Log".

Keeping the UUID out of logs, metrics labels and error reports, and the receiver rate limits, key on the route itself, so they cover /h/ unchanged. Routed tests follow every link and form the pages render to a moved page.

clawbot 1c721ede41 Run the test suite without -v so a failure shows in the build log (next side of #414)
check / check (push) Waiting to run
Details 
script/test now runs go test without -v. The Docker build cuts each step's log at 2 MiB, and the verbose output of the whole suite passed that limit before any failure was printed, so a red script/cibuild showed only passing packages. Without -v, go test prints one result line per package and, for a package that fails, everything its tests wrote, the application's log lines included. -race, -p 4 -parallel 8 and the 90-second per-package timeout are unchanged.

The cause of the red builds was fixed by the cheaper test hashing already on next; the same two changes go to main separately.

clawbot bfdbc937c6 Keep make test under 2 GB of memory (closes #344)
check / check (push) Successful in 3m41s
Details 
Every test that starts a database seeds the admin account, hashing its password with Argon2id at 64 MB, about 150 MB under -race, and internal/handlers and internal/database ran dozens of those at once. That was the memory, and most of internal/handlers' run time; the product code does not leak.

HashPassword now hashes at a 1 MB cost only when testing.Testing() reports a test binary, so every test package gets it with nothing to add and a binary built by go build always hashes at the shipped parameters. TestHashPassword_ShippedParameters still hashes and verifies through HashPassword at the shipped cost. script/test adds -p 4 -parallel 8.

Details

clawbot 515c359e56 Trust the RFC 1918 ranges as proxies when TRUSTED_PROXIES is unset (closes #333)
check / check (push) Successful in 4m43s
Details 
Unset or empty, TRUSTED_PROXIES now defaults to 10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16, so a reverse proxy reaching webhooker from one of those ranges gets per-client rate-limit buckets with nothing set. A set value replaces the default entirely; an unparseable one still fails startup. The startup warning for an empty list is gone.

The README gives the default, one rule (if any client can reach webhooker, or the proxy in front of it, from an RFC 1918 source address, set the list to the proxy's address alone), and where to find that address: the remoteIP field of the http request log line. Loopback is not in the default.

clawbot 30e65dce53 State what the default blocklist covers (closes #244)
check / check (push) Successful in 5m9s
Details 
The README's egress section and the comment above blockedNetworks now state what the default blocklist covers: the IPv4 private and reserved ranges, IPv6 loopback, unique local and link-local addresses, and certain public addresses, each added only because it hands credentials, user data or bootstrap material to whatever can reach it without the caller presenting anything. That is the same material as the rule above alwaysBlockedNetworks, so a future candidate can be accepted or refused against one rule.

A provider's other public addresses, such as 161.26.0.0/16 and 166.8.0.0/14, are not refused. Docs and a comment only; the lists are unchanged.

clawbot 1ac4fe0be4 Show 50 recent events with size, processing time and status (closes #347)
check / check (push) Successful in 4m32s
Details 
The webhook page's list, now headed "50 Most Recent Events", shows the 50 newest events, limited in the query. Each row adds the time received (relative, UTC on hover), the body size, the processing time (slowest delivery, queued to final outcome, retries included, "in progress" while pending), and, when the webhook has exactly one HTTP target, that target's latest HTTP status, coloured by class.

Each event now records its body size in a new body_bytes column when it is stored, so the list never reads bodies; the list loads only the delivery and attempt columns it shows, and a failed load is an error, not an empty list.

An existing event database must be recreated: the column is added in place, with no migration.

Details 
The profile page no longer shows the fixed "Account Type: Standard User" row. webhooker has one account, the administrator it creates, and no account types, so the row was untrue. The Account Information section now lists the username alone, and a test checks the row stays gone.

clawbot 9d29baaa2d Commit the Alpine.js tarball in 3p/ and extract it at build time (closes #345)
check / check (push) Successful in 6m21s
Details 
The build no longer downloads Alpine.js. Its npm package tarball is committed as 3p/alpinejs-3.14.9.tgz, byte for byte the file script/fetch-assets downloaded, with the sha256 that script pinned. script/assets (make assets) extracts package/dist/cdn.min.js to the ignored static/js/alpine.min.js; script/test runs it, so make test, make check, the pre-commit hook and the Dockerfile get the file with no network access, and make build, run and dev run it too.

Removed: script/fetch-assets, its Dockerfile step, static/vendor.sha256 and static/vendor_test.go. The README describes the new flow.

The remedy is to set `TRUSTED_PROXIES` to your reverse proxy's

at startup whenever `TRUSTED_PROXIES` is empty, in every environment,

## Third-party browser assets
The web UI serves one third-party script, Alpine.js. It is **not** committed:
a minified bundle in the tree is unreviewable, and `REPO_POLICIES.md` bars
both committed build artifacts and unpinned external references.
The web UI serves one third-party script, Alpine.js. Its npm package tarball
is committed as `3p/alpinejs-3.14.9.tgz`, byte for byte as the npm registry
publishes it. It is a dependency, not this repo's build output, so
`REPO_POLICIES.md`'s rule against committed build artifacts does not apply.
The directory is `3p/` rather than `vendor/` because Go treats a root
`vendor/` directory as its module vendor directory.
Instead `script/fetch-assets` downloads it from a pinned URL, checks the
download against a hardcoded sha256, and installs it under `static/`. The
sha256 of every installed asset is recorded in `static/vendor.sha256`, and
`static/vendor_test.go` re-hashes the bytes `go:embed` put in the binary
against that manifest — so the pin is enforced on what actually ships, not
merely written down. Any mismatch fails the build.
`script/assets` (`make assets`) extracts the browser build,
`package/dist/cdn.min.js`, from the tarball to `static/js/alpine.min.js`,
where `go:embed` picks it up. `script/test`, `make build` and `make dev` run
it first, and the Dockerfile builds through `make test` and `make build`, so
nothing downloads Alpine.js. The extracted file is not committed, and
`.dockerignore` keeps any host copy out of the build context.
`make bootstrap` runs the fetch for local development, and the Dockerfile
runs it in the build stage; `.gitignore` and `.dockerignore` keep the
artifact out of both the repo and the build context.
To move to a new version: update the version, URL, and tarball sha256 in
`script/fetch-assets` and the asset sha256 in `static/vendor.sha256`, then
run `make assets && make check`.
To move to a new version: download
`https://registry.npmjs.org/alpinejs/-/alpinejs-<version>.tgz`, check it
against the `dist.integrity` hash listed at

#### EventTotals and TargetTotals
Running counts in each event database, read by the statistics pane at the
top of the webhook page. `EventTotals` is one row:
| Field | Type | Description |
| ---------------- | --------- | ----------- |
| `events` | integer | Events ever stored, resubmitted copies included |
| `events_removed` | integer | Events retention has deleted |
| `last_event_at` | timestamp | When the newest event arrived (nullable; empty before the first); retention leaves it as it is |
`TargetTotals` is one row per target, created by the first delivery to it:
| Field | Type | Description |
| -------------------- | ------- | ----------- |
| `target_id` | UUID | The target (primary key) |
| `deliveries` | integer | Deliveries to it ever created, replays included |
| `delivered` | integer | Of those, how many became `delivered` |
| `failed` | integer | Of those, how many became `failed` |
| `deliveries_removed` | integer | Its deliveries retention has deleted |
| `failed_removed` | integer | Its failed deliveries retention has deleted |
Each count changes in the transaction that writes or deletes the rows it
counts. The pane's lifetime events are `events`, and its lifetime
deliveries and failures are `deliveries` and `failed` summed over the
targets; each figure within retention is the same less what retention
removed, so neither needs the rows themselves. Its last event is
`last_event_at`, written in the transaction that stores the event, so it
still shows once retention has removed every event. Its last-10-minutes and
last-24-hours figures are counted from the `events` and `deliveries`
indexes over just that window, the deliveries in one query grouped by
target. Its failure percentage for a window is the deliveries that became
`failed` in it out of all that became `delivered` or `failed` in it, and
a dash when none did.

costs is not the same for every limiter, and the two cases pull in
opposite directions:
- For the **receiver** limits it costs throughput, which is the safe
direction to be wrong in: sharing can only make a limit bind sooner,
never let a sender past it. It matters more for the aggregate limit
than for the per-entrypoint one: with `TRUSTED_PROXIES` unset behind
the reverse proxy a production deployment is required to run behind,
every request keys on the proxy, so the aggregate limit becomes a
service-wide ceiling of 1200 requests per minute across all senders
and all entrypoints, where the per-entrypoint limit's capacity still
grows with the number of entrypoints. Any deployment with more than a
handful of busy entrypoints must set `TRUSTED_PROXIES`.

requests per minute across all senders and all entrypoints, where the

- For the **login and password-change** limits it costs precision, not
availability. Login failures from every client land in one counter,
so a stranger's wrong passwords make the operator's own wrong
passwords answer `429` sooner; the operator's _correct_ password is

#### The login endpoint
The login `POST` is the one endpoint with no pre-emptive limiter in
front of it, and that is deliberate. A limiter that spends budget on
arrival is a lockout in this deployment shape: sharing one bucket, a
arrival is a lockout wherever clients share one bucket, as they do
