Say what a database or log target's attempt did, without a status (closes #388 )

A database or log target sends no HTTP request, yet each of its attempts read "success Status: — (no response)", which for an http target means a failed connection. The shared attempt template now reads a successful database attempt as "archived" and a successful log attempt as "written to the log", and shows no status for either, in the event log and on the event's page. http and slack attempts are unchanged. One test per target type checks both pages. Model: opus-5-5

  `make fmt-check` and `make lint` before the full build begins. The build stage
  then declares an explicit dependency on the lint stage via
  `COPY --from=lint /src/go.sum /dev/null`, which forces BuildKit to complete
  linting before proceeding to compilation and tests. This ensures lint failures
  surface in seconds rather than minutes, without blocking on dependency
  download or compilation in the build stage.
-    ```sh
+    The standard pattern for a Go repo Dockerfile is:
    docker build --no-cache --target lint -t "$(script/projectname)-lint" .
    docker build --no-cache --target test -t "$(script/projectname)-test" .
    ```
    **A stage that is not the last one in the file is built only when the final
    stage's chain depends on it, or when `--target` names it.** That is why the
    two gates are always invoked by name here, and why the final stage carries a
    `COPY --from=` of a harmless file from each of them: without that edge a
    plain `docker build .` builds the last stage alone and exits 0 having linted
    and tested nothing.
    **Every `docker build` in `script/` is tagged**, here and in
    `script/cibuild` and `script/docker`. An untagged build leaves a dangling
    image behind on every invocation, on every developer host and every CI
    runner; a tagged one replaces the previous image.
    Inside a phase the tool is invoked directly — `golangci-lint`, `go test`,
    `eslint`, `prettier` — never through `make lint` or `script/test`, which are
    themselves a `docker build` and would recurse into a daemon that does not
    exist in a build step. Formatting is the exception and stays on the host:
    `script/fmt` writes the working tree, and `script/fmt-check` is its
    read-only twin.
    **No lint verdict may come from a host invocation of the linter.** On a
    shared host golangci-lint reads a result cache keyed on file content rather
    than location, so a second checkout of the same content is served the first
    one's findings, and a host-global lock in `$TMPDIR` makes concurrent runs
    exit non-zero with `parallel golangci-lint is running` — a status a caller
    cannot tell from real findings. Both have produced wrong verdicts in this
    org, in both directions. A container has its own cache, its own `TMPDIR` and
    a digest-pinned binary, so neither is reachable.
 - **Any build that runs checks is built with `--no-cache`.** Docker invalidates
  a `COPY` layer only when the copied content changes, so on an unchanged tree
  the check `RUN` is served from cache, nothing executes, and the build still
  exits 0. Every `docker build` in `script/` therefore passes `--no-cache`:
  `script/lint`, `script/test`, `script/cibuild` and `script/docker` are the
  four, and there is no fifth — `script/check` runs the two gate phases and
  `script/fmt-check`, and builds no image of its own. A bare `docker build .` is
  not evidence that anything ran: a sub-second build reporting success is a
  cache hit, not a result. Never invalidate by pruning — `docker builder prune`
  and friends destroy a build cache shared with every other build on the host.
  When a check is added or changed, prove it works by planting a defect it must
  catch and watching the run fail on it, then revert the defect. A green run
  alone shows neither that the check ran nor that it covers what it should.
 - **The gate phases are separate stages, and the build stage depends on both.**
  The lint phase is based on the `golangci/golangci-lint` image (pinned by
  hash), so lint failures surface in seconds rather than after a full compile,
  and the test phase is based on the Debian Go image. The canonical Go repo
  `Dockerfile`:

    - `.dockerignore` lets `.git` into the build context. It keeps out every git
      `config` at any depth (`**/.git/config`, `**/.git/modules/**/config`): the
      repository's own, each submodule's under `.git/modules/`, and that of a
      submodule keeping its own `.git` directory. `git describe` does not need
      them, and each can hold a credential: a password in a remote URL, or the
      token the CI checkout step stores there. A submodule whose name has a
      `config` segment (`config`, `deploy/config`, `config/lib`) loses its whole
      git directory to `**/.git/modules/**/config`, and Go's version stamping
      then fails the build: give it a name without that segment
      (`git submodule add --name`). The stage that compiles has `git` (the
      Debian Go image has it; an alpine one needs `apk add --no-cache git`) and
      takes the version from the `VERSION` build argument when one is given,
      otherwise from `git describe --tags --always`. That gives the tag on a
      tagged commit; on a later commit, the tag, the number of commits since it
      and the short commit (`v1.2.3-4-gabc1234`); and the short commit when no
      tag is reachable. The stage that compiles also marks its working directory
      safe for git (`git config --system --add safe.directory /src`): a context
      sent as a tar stream keeps the sender's file owners, and git refuses a
      checkout owned by another user, so the version would come out empty.
      `ARG VERSION` has no default, and the build fails if the context carries
      `.git` and the version still comes out empty, `dev` or `unknown`. A plain
      `docker build .` with no build arguments must succeed; a Dockerfile that
      refuses an empty build argument drops that refusal and keeps the argument.

  image build is uncached and so runs the gate phases a second time. That is the
  price of the rule above, and it is worth paying: the image that ships is built
  from a run of its own gates rather than from a cache entry. A separate

  checked by review: to try a change to it, add the feature branch to that list

+    	@go test -timeout 90s -race -cover ./... || \
    		{ echo "--- Rerunning with -v for details ---"; \
-    		  go test -count=1 -timeout 90s -race -v ./...; exit 1; }
+    		  go test -timeout 90s -race -v ./...; exit 1; }
    ```
    `-count=1` is required on both invocations: it defeats Go's test _result_
    cache, so neither run can report a stored pass in place of running the
    tests. It leaves the build cache alone, so it costs the runtime of the suite
    and no recompilation.
    That cache is Go's own, separate from Docker's layer cache. Go stores a
    passing result in its cache directory (`GOCACHE`), and when the same tests
    run again on unchanged code it prints that result, marked `(cached)`,
    without running them. That matters on a developer's machine, where this
    target runs and the directory lasts from one run to the next. The `test`
    phase of the `Dockerfile` needs no `-count=1`: its base image holds no
    result for this repo's tests and nothing before its `go test` step runs a
    test, so there is nothing to replay. `--no-cache` (above) is what makes that
    step run on an unchanged tree.

  semantics, in which an unanchored pattern already matches at every depth; they
  are not a `.dockerignore` and must not be transplanted into one unmodified.
 - **`.dockerignore` does not use `.gitignore` semantics, and copying patterns
  across unmodified leaves secrets in the build context.** Docker matches with
  `moby/patternmatcher`: `filepath.Match` semantics plus a `**` extension, so
  `*` does not cross `/` and a pattern without a leading `**/` is anchored at
  the build-context root. A `.dockerignore` listing `.env`, `*.pem` and `*.key`
  therefore excludes only the copies at the repository root, while `config/.env`
  and `certs/server.key` still reach the context and can land in an image layer
  — which is more dangerous than a short file with no secret patterns at all,
  because it reads as solved and stops anyone looking. Give every
  depth-independent pattern the `**/` prefix and leave only genuinely
  root-anchored entries unprefixed: `.claude`, and the repo's own host-built
  binary, written `/myapp` and never `**/myapp`, which would also match
  `cmd/myapp/` and delete the package directory from the context. Matching is
  case-sensitive, and an ALL-CAPS twin per pattern still misses `Server.Key`, so
  secret names use character ranges — `**/*.[kK][eE][yY]`, `**/*.[pP][eE][mM]`,
  and likewise for `.envrc` and the extensionless SSH keys. Where such a pattern
  also catches something the build needs, re-include it with a negation
  (`!docs/example.env`); deleting the pattern reopens the exposure for every
  other file it covers. Fetch the standard `.dockerignore` from
  `https://git.eeqj.de/sneak/prompts/raw/branch/main/.dockerignore` and extend
  it with the repo's own artifacts.
 - **In-repo agent scratch belongs in both files, written to each file's own
  semantics.** `.claude/` holds one worktree per in-flight agent — an entire
  additional checkout of the repo — so under `COPY . .` the build context
  inflates by a multiple of the repo and another session's unreviewed work can
  be copied into an image layer. In `.gitignore` the entry is `.claude/`,
  unanchored. In `.dockerignore` it is `.claude`, anchored and with **no** `**/`
  prefix, because the prefixed form would also delete any nested directory of
  that name from the build. Anchoring carries a known gap that the canonical
  `.dockerignore` states in its own comment, since consuming repos receive the
  file and not the tracker: the directory is created in the agent's working
  directory, so a repo running agents in subdirectories still ships
  `services/api/.claude/` and must add its own anchored entry there.
 - **A plain `docker build .` of a clone stamps the version that
  `git describe --tags --always` gives**, derived from the `.git` in the build
  context as the canonical `Dockerfile` above shows. Without its failure check,
  a missing `git` or an unreadable checkout would leave `-X main.Version=` empty
  and the build would still exit 0. `script/docker` and `script/cibuild` pass
  the version they compute on the host; it takes precedence. They do this
  byte-identically across repos:
    ```sh
    # Own line: a failing command substitution inside an argument does not
    # trip `set -e`, so the inline form degrades to an empty constant.
    version="$(git describe --tags --always --dirty 2>/dev/null || true)"
    [ -n "$version" ] || version="unknown"
    docker build --no-cache \
        --build-arg VERSION="$version" \
        -t "$(script/projectname)" .
    ```
    `--always` makes an untagged repo yield an abbreviated commit hash rather
    than failing, and the `[ -n "$version" ]` line is the single place the
    fallback is applied — a live check that fires on a build from an export with
    no `.git` and on a repository with no commits yet. Do not fold it into the
    substitution as `|| echo unknown`, which makes the guard unreachable. The
    Dockerfile's side is `ARG VERSION` in the stage that compiles, declared
    there because `ARG` is stage-scoped; passing `VERSION` to a repo whose
    Dockerfile declares no such `ARG` is ignored and costs nothing, which is why
    the scripts stay byte-identical. One consequence for CI: the standard
    checkout action clones shallow and fetches no tags, so a repo that embeds a
    tag-derived version must set `fetch-depth: 0` on its checkout step.
 - **Verify `.dockerignore` by enumerating the image, not by reading the
  patterns.** Plant files at the root _and_ at least two directories deep, build
  a probe image that does `COPY . .`, and list what actually landed
  (`docker run --rm --entrypoint find IMAGE /app`). The `transferring context`
  size is not a substitute: a nested secret is a few bytes, and BuildKit
  transfers only the delta from the previous build.

  which reports `2.14.0 built with go1.27.0 from 114493f9`). A module's `go`
  directive must not name a newer Go minor version than the one golangci-lint
  was built with, or golangci-lint refuses to lint it: this release lints
  `go 1.27.1` but not `go 1.28`. That digest is the only pin, since no repo
  installs golangci-lint on the host. A repo sets the lint phase digest to the
  one named here and re-vendors `.golangci.yml` in the same commit, whichever of
  the two prompted the change: the canonical copy can name linters that an older
  golangci-lint rejects, and a newer golangci-lint can add linters that
  `default: all` switches on until the canonical copy disables them.
 - **`script/bootstrap` installs a pinned tool by comparing versions, never by
  testing presence.** An `if ! command -v <tool>; then install; fi` guard tests
  `PATH` only, so on an already-provisioned machine the pin is inert and a
  version bump is a silent no-op — while the Dockerfile, installing into a clean
  image, gets the pinned version, so a local `make check` and `make docker` can
  disagree about what the tool even is. The canonical form:
    - compares the installed version against the pin over the **whole** version
      token; a parser that stops at the first `-` reports `2.12.2` for a host
      running `2.12.2-rc1` and skips the install;
    - treats absent, non-zero, empty or unrecognised `--version` output as a
      mismatch, so the failure direction is a redundant install and never a
      skipped one;
    - after installing, re-resolves the binary the way callers do — `hash -r`,
      then through `PATH`, not through the directory the installer wrote to —
      and fails naming the resolved path, since an install that a shadowing
      binary hides succeeds while changing nothing any caller sees;
    - is actually called, and prints the version on both success paths: a
      function defined and never invoked has the same exit status and the same
      empty output as one that worked.

 # 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,
  https://git.eeqj.de/sneak/webhooker/issues/279)
 - 2026-08-24 Stamp the build version into the binary and render it in
  the UI footer. `script/version` is the single source — `$VERSION`,
  else `git describe --tags --always --dirty`, else `unknown` — so a
  `make build` binary and a `make docker` image from one checkout
  report the same thing, and nothing in it varies between two builds
  of the same commit, which the release gate's byte-identical
  assertion would catch
  (https://git.eeqj.de/sneak/webhooker/issues/253)
 - 2026-08-24 Derive cookie `Secure` and CSRF strictness from the
  request transport rather than from `WEBHOOKER_ENVIRONMENT`. Behind a
  real TLS proxy with the environment left at its `dev` default, the
  session cookie silently lost `Secure` while the CSRF cookie on the
  same response kept it. `X-Forwarded-Proto` is now matched
  case-insensitively on its first comma-separated element, so `HTTPS`
  and `https, http` no longer fall to the relaxed CSRF path
  (https://git.eeqj.de/sneak/webhooker/issues/269)
 - 2026-08-24 Roll back a failed webhook deletion instead of committing
  it. A failing delete committed whatever had already succeeded,
  hard-deleted the per-webhook event database anyway, and redirected as
  though it had worked — orphaned config plus permanently destroyed
  history, reported as success. All three delete positions now roll
  back with the event database intact

  `(deleted)`, rather than leaving the event log unable to say where a
  delivery went. A deleted target's credentials stay masked exactly as

  receiver, resubmit, replay, the edit form or the toggle

 - 2026-08-24 Bound both request-controlled `/metrics` label dimensions,
  so the unauthenticated receiver is no longer a memory-exhaustion
  vector: `handler` carries the chi route pattern, and `method` folds
  anything chi cannot route onto a single `(unmatched)` sentinel. Both
  were reproduced before the fix — 300 random method tokens took the
  series count from 106 to 7,631, and path flooding reached 62,532 —
  and a label audit across a live scrape found no third unbounded
  dimension (https://git.eeqj.de/sneak/webhooker/issues/254,

 - 2026-08-24 Validate `max_retries` on both target forms. `abc`, `2.7`
  and `-5` silently became 0 — fire-and-forget — including on the edit
  path, where it destroyed a working value, and `999999999` stored
  verbatim. The ceiling of 20 is the `max` both templates already
  declared (https://git.eeqj.de/sneak/webhooker/issues/221)
 - 2026-08-24 Resubmit a stored event as a new undelivered event, so a
  backend under development can be tested against real captured
  traffic. Per-delivery replay cannot serve that: it re-sends one
  finished delivery to its own original target, and a target created
  for a dev backend has no prior delivery to replay. Resubmit
  re-injects the stored event at the top of the receiver path and fans
  it out to whatever targets are active now

  matching the org-wide backstop. `go test` applies `-timeout` per
  package, and `internal/handlers` had grown past the old budget: a
  cache-defeated build failed outright at `GOMAXPROCS=4`, and every run
  under deliberate host load breached 30s. The measurement table lives
  in the script (#194)
 - 2026-08-18 Re-sync `REPO_POLICIES.md` from `prompts`. The local copy
  was stale and still mandated a 20s test target with a 30s timeout,
  which the org replaced with a 60s cap and a 90s backstop. A synced
  copy is not a source; reading it as one nearly produced a PR against
  `prompts` proposing a change already merged there (#196)
 - 2026-08-18 Report handler panics through the logger and answer 500.
  chi v1.5.5's `Recoverer` scans for a `panic(0x` frame the runtime no
  longer emits, then indexes `pkg[-1:]`, so it panicked inside its own
  stack printer before writing a byte: the recovery never ran, the
  client got a dropped connection instead of a 500, and the original
  panic was lost. A local middleware replaces it, bounded by
  `MaxPanicLogLineBytes` (#187)
 - 2026-08-18 Route GORM's logger through `slog` and bound it. Every
  `gorm.Open` left `logger.Default` in place at `Warn` with
  `IgnoreRecordNotFoundError` false, so **every record-not-found
  printed the fully interpolated SQL to stdout** — including the
  client-chosen path on `/webhook/{uuid}` and the submitted username on
  the login form, at no level the operator set and outside
  `internal/logger` entirely. Three call sites, not the two the issue
  named (#178)
 - 2026-08-18 Bound every `slog` line against client-chosen text. Eight
  sites reachable unauthenticated, found by reading every `slog` call in
  the tree rather than only the one reported; the budget moved to a
  shared `internal/logfield` so no second truncation exists. `DEBUG`
  being off by default is not a bound and is not treated as one (#176)
 - 2026-08-18 Stop a slow host turning a login-guard test into a
  segfault. A non-fatal `assert` on an acquire result was dereferenced
  on the next line, so one timing miss killed the whole
  `internal/middleware` binary and reddened CI for unrelated PRs. The
  fix also removed a real production race — `acquire` could shed a
  request with a slot standing free, because Go picks uniformly among
  ready `select` cases (#186)
 - 2026-08-18 Send the chi route pattern to Sentry rather than the

  and `Env` are dropped and headers reduced to an allowlist (#179)

 - 2026-08-18 Verify login credentials before spending rate-limit
  budget, so a flood of wrong passwords cannot lock out the account it
  is guessing at. The manager took this decision rather than stall the
  queue; it is flagged on the issue for reversal (#150)
 - 2026-08-18 Run all linting in Docker via `Dockerfile.lint`. Host lint
  was wrong in both directions from version skew and shared caches.
  `script/lint` asserts the summary line, because `--no-cache-filter`
  silently ignores a stage name it does not match — the flag that makes
  the gate meaningful fails open (#109)
 - 2026-08-18 Serve an event's full stored body over HTTP. The list
  query truncates for rendering, and that truncated value was the only
  way to read a body, so the full payload was unreachable (#157)
 - 2026-08-18 Bound the access log line against client-chosen text.
  `internal/logfield` budgets by *encoded* bytes, not runes, so a
  handler's JSON escaping cannot multiply a field past its allowance
  (#146)
 - 2026-08-18 Mark superseded CI commits `failure` rather than
  `skipped`. A skipped run rolls up green, so a commit that was never
  tested reported success (#152)
 - 2026-08-18 Set `fx.StopTimeout` inside the container stop grace, so
  shutdown hooks are bounded by a deadline the orchestrator will
  actually honour rather than being killed mid-flush (#134)
 - 2026-08-17 Bucket IPv6 rate-limit keys by `/64`. A single allocation
  hands out 2^64 addresses, so per-address keying let one client mint
  unlimited buckets. Manager decision, recorded on the issue (#125)
 - 2026-08-17 Correct release-blocking README and startup-warning
  inaccuracies, including claims about behaviour the code does not have
  (#151)
 - 2026-08-17 Fetch and verify Alpine.js at build time against
  `static/vendor.sha256` instead of committing the minified blob, so
  the dependency is pinned by hash rather than by trust (#145)
 - 2026-08-17 Bound the event log's rendered bodies in the query itself,
  so a large stored payload cannot be read into memory just to be
  truncated for display (#135)
 - 2026-08-17 Mask the `http` target's destination URL in the UI: it can
  carry a bearer credential in its path or query, and was rendered
  verbatim. Manager decision to mask unconditionally (#115)
 - 2026-08-14 Bound shutdown hooks by their stop context, so a hook that
  hangs cannot hold the process past its grace period (#102)
 - 2026-08-14 Render templates via a buffer rather than the
  `ResponseWriter`, so a template error part-way through cannot commit
  a 200 and then fail — the response is written only once it is whole
  (#123)
 - 2026-08-14 Align the session codec's max-age with the 7-day absolute
  cap. The codec accepted cookies the session layer considered expired,
  so the cap was enforced in one place and not the other (#108)
 - 2026-08-12 Warn when `TRUSTED_PROXIES` is empty in production, where
  the safe default silently discards forwarded headers and every client
  rate-limits as the proxy's address (#149)
 - 2026-08-12 Bound the receiver rate limit per client IP across the
  whole `/webhook/*` route. The existing limiter keyed on the request
  path and `/webhook/{uuid}` matches any single segment, so a client
  that invented a fresh path per request minted a fresh bucket per
  request: the limit on the only unauthenticated endpoint bounded
  nothing in aggregate, and every request still cost an entrypoint
  lookup before it 404ed. An outer limiter keyed on the client address
  alone now bounds that, chained in front of the unchanged
  per-entrypoint limiter (#139)
 - 2026-08-12 Correct release-blocking documentation inaccuracies: the
  README promised manual redelivery in the present tense in three
  places when nothing implements it (the same false claim also sat in
  the doc comment that was its source text), the env table omitted
  `RETENTION_SWEEP_INTERVAL`, and `TODO.md` itself omitted five landed
  units (#141)
 - 2026-08-12 Make the CI gate execute the checks it reports on. The
  workflow now writes a build-context fingerprint before calling
  `script/cibuild`, so a code commit invalidates the `COPY` layer of
  the lint and builder stages while a docs-only commit still replays
  from cache; a superseding run also rewrites the `failure` status
  Gitea leaves on commits it cancelled and never tested. Verified by
  pushing a deliberately broken test and watching CI go red (#119)
 - 2026-08-12 Require a positive `RETENTION_SWEEP_INTERVAL`: a
  non-positive value reached `time.NewTicker` in both the retention
  reaper and the archive sweeper, panicking two goroutines with no
  recover after startup had already reported success (#140)
 - 2026-08-12 Bound the `X-Forwarded-For` scan's allocation to the hop
  cap: the reverse walk cuts entries with `strings.LastIndexByte`
  instead of joining and splitting, so a 1 MB header allocates 16 bytes
  rather than 1.6 MB per request on the unauthenticated receiver.
  Semantics proven unchanged by differential testing against the
  previous implementation (#133)
 - 2026-08-12 Cap the `X-Forwarded-For` hop walk at 64 entries, so an
  attacker-supplied chain cannot burn unbounded CPU in the rate-limit
  key function; running off the end falls back to the peer address
  (#124)
 - 2026-08-12 Gate forwarded-header trust behind a `TRUSTED_PROXIES` CIDR
  list: all three rate limiters key on the connection's own address
  unless the direct peer is a configured proxy, in which case
  `X-Forwarded-For` is walked right to left for the first non-proxy hop.
  Default trusts nothing, and a set-but-unparseable value aborts
  startup. Before this, any client could mint a fresh bucket or drain
  another's by rotating a spoofed header (#88)
 - 2026-08-11 Web UI cleanup: nav terminology unified on Webhooks, the
  Profile settings placeholder removed, a progressive-enhancement copy
  button for the entrypoint URL, and retention form copy that states the
  actual policy (deletion by the reaper, 0 retains forever) (#57)
 - 2026-08-11 Mask the webhook credential in delivery errors and logs:
  Go embeds 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)
 - 2026-08-11 Rate-limit the public webhook receiver endpoint
  (`RECEIVER_RATE_LIMIT`, default 120/min), keyed on client IP plus
  entrypoint path so one entrypoint cannot exhaust another's budget;
  over-limit requests get 429 with `Retry-After`. It was the one
  unauthenticated, internet-facing endpoint with no limit at all (#64)
 - 2026-08-11 Enforce the body size limit before CSRF parses the form:
  `MaxBodySize` is now first in all four form-parsing route groups, so
  an oversized request is rejected with 413 instead of being read in
  full by the CSRF middleware before any cap applied (#90)
 - 2026-08-11 Mask target config on the source detail page, which
  rendered the stored blob verbatim and so exposed the Slack
  incoming-webhook URL — a bearer credential that cannot be revoked
  per-holder. Config reaches the template only as a `TargetView` of
  labelled fields, and header values are rendered as a count (#113)
 - 2026-08-11 Allow `retention_days` of 0 to mean retain forever, via a
  sentinel 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)
 - 2026-08-09 Inactivity-based session timeout: sliding idle expiry
  (`SESSION_IDLE_TIMEOUT`, default `24h`) refreshed on authenticated
  requests, with the 7-day absolute cap kept as an independent
  backstop that activity never extends (#66)
 - 2026-08-09 Restart recovery and the 60s retry sweep terminally fail an
  orphaned `retrying` delivery whose target type no longer supports
  retries, recording a `DeliveryResult` with the reason instead of
  leaving the delivery stuck forever (#82)
 - 2026-08-09 Root the delivery engine's worker pool and the retention
  reaper's sweep loop at `context.Background()` rather than the fx
  `OnStart` hook context (#97), which carries fx's 15s start timeout and
  killed both roughly fifteen seconds after boot: the proxy silently
  stopped delivering webhooks entirely, and the reaper never ran a
  single sweep under its default one-hour interval
 - 2026-08-09 Archive writer lifecycle (#89): deleting a webhook (or its
  last `database` target) evicts the cached archive writer and closes
  its handle while deliberately leaving `archive-{webhookID}.db` on
  disk, and a new `ArchiveSweeper` prunes idle archives on the existing
  `RETENTION_SWEEP_INTERVAL` without ever creating an archive file
 - 2026-08-09 Configuration parsing fails loudly on set-but-unparseable
  environment values: `envInt` removed in favour of `envPositiveInt`
  plus a `PORT` range check, `envBool` now parses with
  `strconv.ParseBool`, and defaults apply only to unset variables (#80)
 - 2026-08-07 Automatic event retention cleanup based on
  `retention_days`, deleting expired events, deliveries, and delivery
  results from each per-webhook event database (#63)
 - 2026-08-07 Update golangci-lint to v2.12.2 (Docker image digest in
  `Dockerfile`, release-archive sha256 pins in `script/bootstrap`),
  adopt the canonical `.golangci.yml` (v2 `linters.settings` layout so
  `lll`/`funlen`/`cyclop`/`dupl` thresholds actually apply), and fix
  all newly surfaced lint findings
 - 2026-07-07 Adopted scripts-to-rule-them-all: `script/` entrypoints,
  Makefile shims, README Entrypoints section
 - 2026-03-25 pin golangci-lint Docker image for linting (#55)
 - 2026-03-18 CSRF middleware detects TLS per-request, fixing login over
  plain HTTP and behind reverse proxies (#54)
 - 2026-03-17 root path redirects based on auth state (#52)
 - 2026-03-17 CSRF protection, SSRF prevention for HTTP delivery targets
  with DNS rebinding defense, and per-IP login rate limiting (#42)
 - 2026-03-17 Slack target type for incoming webhook notifications (#47)

 - 2026-03-04 tests for delivery, middleware, and session packages
  (#32); removed the build-architecture global (#31)
 - 2026-03-04 1.0 MVP merge: Webhook/Entrypoint/Target rename, core
  delivery engine with bounded worker pool and circuit breaker,
  parallel fan-out, per-webhook event databases, management UI (#16)
 - 2026-03-01 repo brought to REPO_POLICIES standards; TODO.md folded

 # Future Steps
- Per-webhook rate limits, set in the web UI and enforced in the receiver
+- Delivery status and retry management UI. Replay of a terminally
-  handler, on top of the receiver's existing limits, which `RECEIVER_RATE_LIMIT`
+  failed delivery and per-attempt detail already landed
-  sets for the whole server (see Rate Limiting in the README)
+  (https://git.eeqj.de/sneak/webhooker/issues/203,
- API key authentication for programmatic access (the `APIKey` model exists, but
+  https://git.eeqj.de/sneak/webhooker/issues/202)
-  nothing creates a key and no middleware checks one)
+- Per-webhook rate limiting in the receiver handler (per-webhook config
  plus handler enforcement; global limits must not apply to receiver
  endpoints)
 - API key authentication for programmatic access (APIKey model exists;
  Bearer token middleware does not)
 - REST API v1
    - CRUD for webhooks, entrypoints, targets
    - event viewing and filtering endpoints
    - event redelivery endpoint
    - OpenAPI specification
- Analytics in the web UI: response times summarised per webhook or per target,
+- Analytics dashboard: success rates, response times, volume
-  and figures for all webhooks together. The webhook page already shows event,
+- A remember-me option at login
-  delivery and failure counts and failure percentages, the target list counts
+- Password reset flow for a forgotten password over the web. The
-  each target's deliveries, the event log and each event's page show every
+  authenticated password *change* flow already landed, and a lost
-  attempt's duration, and `/metrics` carries server-wide counts and delivery
+  password is recoverable from the console with `webhooker resetpw`
  durations
 - A remember-me option at login. Every session already survives a browser
  restart: it lasts up to 7 days, and ends sooner after `SESSION_IDLE_TIMEOUT`
  (default 24 hours) without activity
 - Password reset flow for a forgotten password over the web. The authenticated
  password _change_ flow already landed, and a lost password is recoverable from
  the console with `webhooker resetpw`
  (https://git.eeqj.de/sneak/webhooker/issues/208)
 - Later, nice to have
    - email delivery target type
    - SNS and S3 delivery targets
-    - data transformations (e.g. a configurable Slack message format; the Slack
+    - data transformations (e.g. webhook to Slack message formatting)
-      target sends one fixed format today)
+    - JSONL file delivery with periodic S3 upload
-    - JSONL file delivery with periodic S3 upload (the `database` target already
+    - webhook event search and filtering
-      archives events to SQLite files, rotated hourly, daily or monthly if set,
+    - multi-user with role-based access control
      and the webhook page offers them as one gzipped JSON download)
    - webhook event search, and filtering beyond the event log's failed and
      pending views
    - multi-user with role-based access control (each webhook already belongs to
      one account, but there is only the account made at first boot and no way
      to add another)
