A notification endpoint that answered with a redirect was counted as
delivered: the request is not sent through a client, so the redirect
is never followed, and only a status of 400 or more counted as a
failure. Now any status outside 200-299 fails the delivery for ntfy,
Slack and Mattermost, so it is retried and logged like the others.
Model: opus-5-5
With debug logging on, each delivery logged the full Slack, Mattermost
or ntfy URL, whose path or query lets anyone who has it post to the
channel or topic. The two debug lines now give the endpoint's name and
the title; sendSlack is told which of Slack or Mattermost it sends to.
A webhook URL that does not parse gave a startup error quoting the
whole URL; it now gives only the reason. Errors from a failed request
come from the transport, not from an HTTP client, and carry no part of
the path or query; a test now checks that too.
Model: opus-5-5
Mattermost is sent by the Slack sender, which wrapped every HTTP error
status in ErrSlackFailed, so a Mattermost endpoint answering 503 was
logged as "slack notification failed". The sender now takes the error
to wrap: the Slack endpoint passes ErrSlackFailed and the Mattermost
endpoint passes ErrMattermostFailed, which was defined but unused.
A new delivery test sets both endpoints to a stand-in server answering
503 and checks the error logged for each names its own endpoint.

Updates golangci-lint to v2.12.2 and sets `.golangci.yml` to the org-standard v2-schema config already deployed across the org's repos. The config change is owner-authorized (see #96 (comment) and #96 (comment)); the same file is being landed as canonical via prompts PR #24 (sneak/prompts#24).
## Changes
- **Commit-pinned installs**: golangci-lint pinned to commit `c0d3ddc9cf3faa61a4e378e879ece580256d76e5` (v2.12.2, released 2026-05-06) in `Dockerfile` and `script/bootstrap`.
- **`.golangci.yml` set to the org-standard v2 config** (sha256 `021cc83f4e6fc7c31b95b34b846723dfcf20b66b7baeea1dc40406e643346bcb`), byte-identical to the file used across the org's other repos. Settings live under `linters.settings`, so the `lll`/`funlen`/`cyclop`/`dupl` thresholds are actually applied (under the old hybrid file, v2 silently ignored the top-level `linters-settings` block).
- **Lint fixes** required by the now-active thresholds:
- `goconst`: shared constants for repeated status/priority/DNS-fixture strings in `internal/watcher/watcher.go` and the notify, state, and watcher tests
- `dupl`: consolidated duplicated ntfy/slack HTTP-error tests and SendNotification endpoint-error tests behind shared helpers in `internal/notify/delivery_test.go`
- `lll`: wrapped long test table entries and comments in `internal/config/classify_test.go`, `internal/notify/history_test.go`, `internal/state/state_test.go`, `internal/watcher/watcher_test.go`; shortened one inline nolint justification in `internal/notify/retry.go`
- **`TODO.md`**: Completed Steps entry updated in the same commit.
- Rebased onto current `main` (`f79cd98`); the branch is one clean commit.
## Notes
- v2.12 deprecates the `gomodguard` linter in favor of `gomodguard_v2`. The org-standard config does not disable the deprecated linter, so golangci-lint may emit an informational deprecation warning; this is accepted by the owner and does not affect the exit status (this exact config+code combination was CI-green at `dea7e44`).
## Verification
- `make check` exits 0 (fmt-check, tests, lint)
- `make lint`: 0 issues; no deprecation warning surfaced in the runs performed
- sha256 of `.golangci.yml` at HEAD verified equal to `021cc83f4e6fc7c31b95b34b846723dfcf20b66b7baeea1dc40406e643346bcb`
