sneak d871bf2d6c Run the test suite without -v so a failure shows in the build log (closes #414)
check / check (push) Successful in 4m8s
Details 
The Docker build cuts each step's log off at 2 MiB. script/test ran
go test -v, whose output for the whole suite passed that limit before
any failure was printed, so a red build showed no failing test. Without
-v, go test prints one result line per package and, for a package that
fails, everything its tests wrote, application log lines included.
-race and the 90s per-package timeout are unchanged.

clawbot 68759dc8e1 Keep make test under 2 GB of memory (closes #344) 
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.

authoritative list, and the only place to read a count or a state of play from.
This file records where the project is, not what is in flight: a sentence whose

wrong the moment it merges, and this file has been wrong that way

The durability defect that held the tag has landed
(https://git.eeqj.de/sneak/webhooker/issues/256, commit `8d64259`). Every SQLite
handle opens with WAL journaling and a busy timeout, a bookkeeping write that
fails leaves its delivery in a recoverable state rather than a lying one, and
recovery skips a delivery that already has a successful result row. Final
pre-tag verification exercised it and confirmed it holds. Whatever the milestone
still shows open is what remains before `v1.0.0`.

exercised it and confirmed it holds. Whatever the milestone still

Delivery is at-least-once by design, not by accident: a send whose result row
does not land is attempted again, so a receiver can see a duplicate. That is
deliberate — the alternative is a silent lost delivery — and the README says so
under Rationale. It is not a defect to re-file.

One caveat on reading a green check: a docs-only commit deliberately
replays from the layer cache
(https://git.eeqj.de/sneak/webhooker/issues/119), so a green status on
such a commit evidences a replay rather than an executed run. A code
commit invalidates the `COPY` layer and genuinely executes.
# Next Step
Clear the rest of the open 1.0.0 milestone
(https://git.eeqj.de/sneak/webhooker/milestone/9) and tag `v1.0.0`. Merging
`next` into `main` is a separate act from tagging and waits on neither of those:
`next` is kept mergeable at all times, which is the point of the branch.

# Completed Steps
- 2026-08-24 Bind the plaintext HTTP listener deliberately, via `BIND_ADDRESS`
defaulting to `127.0.0.1`, and document the reverse-proxy deployment. A
hostname, an empty value or a value carrying a port is a startup error, and
the `Dockerfile` sets `0.0.0.0` because a loopback bind inside a container is
unreachable (https://git.eeqj.de/sneak/webhooker/issues/268). The same commit
removed the shutdown race: `httpServer` is built in the constructor rather
than assigned from the serving goroutine, which orders the write before every
fx hook and rules out the nil dereference a SIGTERM arriving first would have
caused, and `sentryEnabled` is an `atomic.Bool`
(https://git.eeqj.de/sneak/webhooker/issues/226)
- 2026-08-24 Remove inbound request signature verification. The entrypoint UUID
is the authentication secret, so the per-entrypoint shared secret, the
`internal/signature` package, the receiver check, the model fields and the
forms are all gone. This reverses the feature that landed earlier in the same
milestone (https://git.eeqj.de/sneak/webhooker/issues/67,

entrypoint UUID is the authentication secret, so the per-entrypoint
shared secret, the `internal/signature` package, the receiver check,
the model fields and the forms are all gone. This reverses the
feature that landed earlier in the same milestone

nothing in it varies between two builds of the same commit, which the release

peer is a configured proxy, in which case `X-Forwarded-For` is walked right to

fresh bucket or drain another's by rotating a spoofed header (#88)

the request URL in `*url.Error`, so every transport failure persisted the full
Slack webhook URL into the per-webhook event database via
`DeliveryResult.Error`, a field a future REST API would have served.
`maskURLError` drops path, query and userinfo while preserving the wrapped
cause, so `errors.Is`/`As` and `Timeout()` still work and DNS, TLS and timeout
failures still read differently (#118)

count (#113)

written in `BeforeSave` so the GORM column default cannot win the race. Also
bounds the reaper's cutoff arithmetic: day counts above 106751 overflowed
`time.Duration` and wrapped the cutoff into the future, where every row
matched and the sweep deleted everything (#79)
