 # .dockerignore does NOT use .gitignore semantics. Docker matches with
 # moby/patternmatcher: filepath.Match plus `**`, so `*` does not cross
 # `/` and an unprefixed pattern is anchored at the context root. Every
 # depth-independent pattern therefore needs `**/`, or `config/.env` and
 # `certs/server.key` still ship while this file reads as solved. Only
 # genuinely root-anchored entries go unprefixed. Never transplant these
 # into .gitignore, where `**/` is wrong.
 #
 # Matching is case-sensitive, so secrets use character ranges rather
 # than an ALL-CAPS twin, which would still miss `Server.Key`.
 #
 # Extend with this repo's own host-built artifacts, written anchored:
 # `/myapp`, never `**/myapp`, which also matches `cmd/myapp/` and
 # deletes the package directory from the context.
 # .git is sent without its config. Without a VERSION build argument the
 # stage that compiles runs `git describe --tags --always` on .git, which
 # does not need .git/config; that file can hold a credential, such as a
 # password in a remote URL or the token the CI checkout step stores there.
 # Each submodule keeps a config with the same exposure in its git directory
 # under .git/modules/, nested again for a submodule's own submodules, or in
 # its own .git directory when it keeps one.
 # KNOWN GAP: a submodule whose name has a `config` segment (`config`,
 # `deploy/config`, `config/lib`) loses its whole git directory, because
 # `**/.git/modules/**/config` also matches that segment's directory
 # under .git/modules/. Go's version stamping then fails the build;
 # nothing leaks. Name such a submodule without that segment:
 # `git submodule add --name`.

 **/.git/modules/**/config
 # Agent scratch: one full checkout of the repo per in-flight agent.
 # Anchored because it occurs once where agents run at the repo root.
 # KNOWN GAP: a repo running agents in subdirectories still ships
 # `services/api/.claude/` and must add its own anchored entry.

 # RouteWatch
-RouteWatch is a real-time BGP routing table monitor that streams BGP UPDATE messages from the RIPE RIS Live service, maintains a live routing table in SQLite, and provides HTTP APIs for querying routing information.
+RouteWatch is an MIT-licensed Go daemon by @sneak that monitors the BGP routing
 table in real time: it streams BGP UPDATE messages from the RIPE RIS Live
 service, maintains a live routing table in SQLite, and provides HTTP APIs for

 - **Backpressure**: Probabilistic message dropping when queues exceed 50% capacity
 - **Graceful Shutdown**: 60-second timeout, flushes all pending batches
 - **Reconnection**: Exponential backoff (5s-320s) with reset after 30s of stable connection
- **IPv4 Optimization**: IP ranges stored as uint32 for O(1) lookups
+- **IP Lookup**: the most specific live route is found by looking up the
  address's prefix at each mask length, longest first, in the prefix index

  `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.
-    The standard pattern for a Go repo Dockerfile is:
+    ```sh
    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

    - `.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.

  `*` 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`

  also catches something the build needs, re-include it with a negation

  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.
 - **No build artifacts in version control.** Code-derived data (compiled
  bundles, minified output, generated assets) must never be committed to the

  configuration changes are made to the canonical copy in the `prompts` repo and
  reach consuming repos by re-vendoring; an agent may open a PR against
  canonical, which only the user merges. One list is exempt from byte-identity,
  because it cannot be written once for every repo: the `deny` list of the
  `test-support` depguard rule, where a repo names its own test-support packages
  by full import path. A repo adds entries there and changes nothing else, and a
  re-vendor carries its entries forward. The canonical golangci-lint version is
  v2.14.0 (released 2026-09-24), pinned as the digest of the lint phase's base
  image
  (`golangci/golangci-lint@sha256:ad862ba6b3798cbe0fd9fd7408d498fd74fbd2623a92406b2fd3898faf0bf98f`,
  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.
    Keep it POSIX sh: no arrays, no `[[`, no `grep -P`.
    A Go tool a repo needs on the host is installed with `go install` pinned to
    a commit hash (`go install <package>@<commit hash>`). It is never tracked as
    a `go.mod` tool dependency or through a `tools.go` file, either of which
    pulls the tool's own dependencies into the repo's `go.mod` and `go.sum`.

 # Completed Steps
 - 2026-10-03: `/api/v1/stats` serves the prefix distribution from memory,
  seeded at startup and adjusted on every live-route write, so a request no
  longer reads every live route (closes #30)
 - 2026-10-03: a new database is created with `auto_vacuum` set to
  incremental, through the connection string so it is set before the file
  is first written, and each periodic incremental vacuum now returns up to
  1000 free pages; the late `PRAGMA auto_vacuum` in `Initialize`, which
  SQLite ignored, is gone (closes #43)
 - 2026-10-03: looking up an IP address no longer reads every IPv6 route:
  both families find the most specific live route with at most 33 or 129
  lookups on the prefix index, and the IPv4 range columns are gone. Prefixes
  from the feed are stored in one text form, so an IPv6 withdrawal, which the
  feed sends uncompressed, now removes its route (closes #48)
 - 2026-10-02: a plain `docker build .` stamps the commit's tag or short
  commit (`git describe --tags --always`) into the page footer instead of
  `unknown`: `.dockerignore` sends `.git` without `.git/config`, a `VERSION`
  build argument takes precedence, and `make build` stamps the same value
  (closes #46)
 - 2026-09-29: the entrypoint creates the data directory if it is missing and
  stops the start if a step fails; README "Running under upaas" no longer
  asks for the host directory to be created first (closes #42)
 - 2026-09-29: `.dockerignore` keeps `.git`, local build output, local
  databases and `.env` out of the Docker build context, and so out of the
  source archive in the image (closes #39)
 - 2026-09-29: README first line names the MIT license and the author;
  the License section now says MIT and links `LICENSE`, and an Author
  section was added; this file brought up to date (closes #38)
 - 2026-09-29: MIT `LICENSE` (closes #1)
 - 2026-09-28: stopping the daemon while the feed is flowing no longer
  panics with "send on closed channel": the read loop checks for a stop
  just before handing a message to the handler queues, and a second
  `Stop` no longer closes the queues again (closes #34)
 - 2026-09-28: `docker stop` no longer kills the daemon 2 seconds after the
  stop signal: the entrypoint switches to the `routewatch` user with
  `setpriv` instead of `runuser`, so the daemon receives the signal itself
  and gets the whole wait `docker stop` allows, up to its own 60-second
  limit (closes #33)
 - 2026-09-28: ready to run under upaas: a set but invalid `PORT`,
  `XDG_DATA_HOME` or `MALLOC_ARENA_MAX` stops the start, the health
  check follows `PORT`, README "Running under upaas" section (closes
  #31)
 - 2026-09-22: realtime in-memory database statistics: counts seeded at
  startup and adjusted on every write, oldest/newest route timestamps via
  index-end lookups; `/api/v1/stats` no longer scans the tables (closes
  #27)
 - 2026-09-21: batch writes take the write lock when their transaction
  begins (`_txlock=immediate`), so they wait out a WAL checkpoint instead
  of failing with "database is locked" (closes #25)
 - 2026-09-21: `MALLOC_ARENA_MAX=2` in the image caps glibc malloc arenas,
  so memory outside the Go runtime no longer grows with the core count
  (closes #23)
 - 2026-09-21: `GOMEMLIMIT=1536MiB` in the image; README Memory section
  with the memory budget and the 5 GiB container limit (closes #13)
 - 2026-09-21: the four handler queues hold at most 20,000 messages each,
  down from 100,000 (closes #11)
 - 2026-09-21: two goroutine leaks fixed: the stats handlers after a
  timeout and the streamer's tickers on every reconnect (closes #12)
 - 2026-09-21: parsed RIS messages no longer keep the unused `Community`
  and `Raw` fields (closes #9)
 - 2026-09-21: `.editorconfig`, and a Gitea workflow that runs
  `script/cibuild` on every push (closes #14)
 - 2026-09-21: the peering handler's AS-path map holds at most 500,000
  paths and is swapped for an empty one every 30 seconds instead of copied
  (closes #10)
 - 2026-09-21: SQLite memory bounded across the whole connection pool: a
  64 MiB page cache on each connection, 1 GiB soft and 1.5 GiB hard heap
  limits (closes #8)
 - 2026-09-21: the Docker build runs the format check, the linter and the
  tests, linting in a separate stage on a golangci-lint image pinned by
  digest (closes #5)
 - 2026-09-21: `make test` skips the live-network feed test (`-short`), so
  `make check` no longer depends on the network (closes #2)

Author	SHA1	Message	Date
sneak	7de2066bf2	WIP: re-vendor canonical files and gate phases check / check (push) Canceled after 0s Details Model: opus-5-5	2026-10-14 12:35:07 +00:00
sneak	00e51d284f	Merge pull request 'Next milestone: production memory under 5 GiB, ready for upaas' (#6 ) from next into main check / check (push) Canceled after 0s Details Reviewed-on: #6	2026-10-06 00:34:48 +02:00
clawbot	a9b68608c6	Serve the /api/v1/stats prefix distribution from memory (closes #30 ) check / check (push) Successful in 3m19s Details The prefix distribution was the last query on the stats path. It read one index entry per live route on every request, so on a large database it took the whole 4-second deadline and /api/v1/stats answered 500. The distribution now lives next to the in-memory counts: seeded once at startup from the same query, then kept exact by every live-route write. A new route whose prefix had no live route adds one at its mask length; a delete that leaves a prefix with no live route takes one away. Each check is one lookup on the prefix index, within the same write. The single-route delete now runs its delete and that lookup in one transaction. Model: opus-5-5	2026-10-03 18:43:58 +02:00
clawbot	44a5f4cdca	Create new databases with auto_vacuum incremental (closes #43 ) check / check (push) Successful in 2m50s Details SQLite only accepts auto_vacuum before the database file is first written. The connection switched to WAL first, which writes the file, so the PRAGMA auto_vacuum in Initialize came too late and was ignored. The setting now goes in the connection string, which the driver applies on open before the journal mode, and the late PRAGMA is removed. Vacuum now reads every row PRAGMA incremental_vacuum returns: SQLite frees one page per row, and the single step ExecContext took freed only one page per call. Tests check that every pooled connection sees auto_vacuum incremental on a new database and that one Vacuum call frees every page left by deleting routes. Model: opus-5-5	2026-10-03 17:09:29 +02:00
clawbot	32704c601e	Look up IP addresses by prefix at each mask length (closes #48 ) check / check (push) Successful in 3m13s Details Looking up an address on /ip/ and /api/v1/ip/ read every IPv6 live route and about half of the IPv4 range index, so on a day-sized database it passed the 30-second request timeout. The lookup is now one function for both families: from the longest mask length down, it looks up the address's network prefix on the existing prefix index, and the first live route wins. The feed sends IPv6 withdrawals uncompressed, so they never matched the stored compressed prefix and never removed a route. Prefixes are now stored in the text form net/netip prints, so IPv6 withdrawals take effect. ip_start, ip_end and GetASInfoForIP are removed; nothing read them. A database from before this change must be deleted. Model: opus-5-5	2026-10-03 16:04:38 +02:00
clawbot	7322f936e4	Stamp the git tag or short commit in a plain docker build (closes #46 ) check / check (push) Successful in 3m6s Details A plain `docker build .` stamped `unknown` into the page footer: .dockerignore left out .git, and the Dockerfile built without the -X flags. The context now carries .git without .git/config, which can hold a credential. The build stage takes the VERSION build argument when one is given, otherwise `git describe --tags --always`, fails the build if .git is present and no version comes out, and stamps it together with the full commit the footer links to. `make build` now uses `git describe` as well, and script/docker is the current shared copy.

clawbot	6422d9fa0c	Container makes its data directory usable itself (closes #42 ) check / check (push) Successful in 8s Details sneak's standing rule: the container makes its data directory usable itself, with no step on the host. entrypoint.sh now creates /var/lib/berlin.sneak.app.routewatch if it is missing and stops the start when any step fails (set -euo pipefail); before, a failed cd went on to change the ownership of whatever directory the script was in, and a failed chown still started the daemon. Taking ownership of the directory and switching to the routewatch user through setpriv are unchanged. The README's upaas volume line now says only which path to mount. The empty-directory and other-uid cases were run by hand on the built image with upaas-style bind mounts, not added as an automated test. Model: opus-5-5	2026-09-29 12:23:42 +02:00
clawbot	057e0bd9a9	Add a .dockerignore (closes #39 ) check / check (push) Successful in 6s Details Adds a .dockerignore, which REPO_POLICIES.md lists among the files every repo has. Until now every docker build sent the whole working tree as its build context, and the image's source archive is made from that context. It now keeps out .git, local build and test output, archives, local databases, .env and a local Go workspace. Every tracked file stays in, so the format check, the linter, the tests, the build and the source archive read the same files as before. Without .git in the context the binary's build info records no git revision; nothing in routewatch reads it. Model: opus-5-5	2026-09-29 07:42:20 +02:00
clawbot	87a3bc115e	README: license and author up front; bring TODO.md up to date (closes #38 ) check / check (push) Successful in 3m14s Details Brings README.md and TODO.md in line with REPO_POLICIES.md and with what is on next. The README's first line now names routewatch, what it is, its MIT licence and its author, @sneak; the License section says MIT and links LICENSE; a new Author section names @sneak. TODO.md's Status, Next Step and Future Steps now describe next as it is: it waits for sneak to merge the milestone PR, after which the upaas deploy and the run under a real 5 GiB limit are his. Completed Steps gains a line for each issue that landed without one. Docs only. make fmt formats only Go here, so the markdown was wrapped by hand. Model: opus-5-5	2026-09-29 07:06:30 +02:00
clawbot	d28a59023a	Add MIT LICENSE (closes #1 ) check / check (push) Successful in 4m5s Details Adds LICENSE with the MIT licence sneak chose for routewatch, copied byte for byte from sneak/webhooker's LICENSE: copyright 2026, Jeffrey Paul. The rest of the issue, .editorconfig and the Gitea check workflow, was already on next, and the README already points at LICENSE. Judgement call: our repos write the copyright holder in several different ways and sneak named no form; webhooker's gives his full name and email address, the most explicit of them. Model: opus-5-5	2026-09-29 05:05:35 +02:00
clawbot	1ac24669d3	Stop the streamer without sending on closed queues (closes #34 ) check / check (push) Successful in 2m38s Details Stopping the daemon while the RIS Live feed was flowing could panic with "send on closed channel" and skip the rest of the shutdown. Stop cancels the stream and closes the handler queues under the streamer's write lock, but the read loop checked for a stop only before parsing each line. It now checks again under the read lock it already takes just before handing a message to the queues, so it never sends to a closed queue. Stop also clears its cancel function and returns early when there is none, so a second call no longer closes the queues again. A test forces both cases. Behaviour change: Stop before Start now does nothing. Model: opus-5-5	2026-09-28 21:42:33 +02:00
clawbot	6187ac8503	Let the daemon receive docker stop's signal itself (closes #33 ) check / check (push) Successful in 2m42s Details entrypoint.sh now switches to the routewatch user (UID 1000) with setpriv instead of runuser. setpriv replaces itself with the daemon, so the daemon is the container's main process and receives docker stop's signal itself. runuser stayed in between, passed the signal on and killed the daemon 2 seconds later, so every stop ended with exit 143. The daemon now gets the whole wait the caller allows, up to its own 60-second limit, and a clean stop exits 0. Taking ownership of the state directory and the MALLOC_ARENA_MAX check still run as root first. Not fixed here: a stop while the feed is flowing can still panic (#34). Model: opus-5-5	2026-09-28 21:08:33 +02:00
clawbot	f2a9e90625	Refuse invalid settings at start, health check follows PORT (closes #31 ) check / check (push) Successful in 3m17s Details A set but invalid PORT (anything but plain digits from 1 to 65535) or a relative XDG_DATA_HOME now stops the start before the database opens; before, a bad PORT left the daemon running without HTTP. entrypoint.sh refuses a MALLOC_ARENA_MAX that is not a positive whole number, since glibc ignores a bad one silently. The HEALTHCHECK probes the port PORT names, 8080 when unset. PORT is now read in internal/config, so server.New takes the config. The README gives the real Linux state directory, lists XDG_DATA_HOME, and adds "Running under upaas": port, volume, environment, the 5g memory limit and the health check. Unverified: the 5g memory limit could not be exercised on the build host. Model: opus-5-5	2026-09-28 20:08:42 +02:00
clawbot	df9e23d503	Serve /api/v1/stats counts from realtime in-memory counters (closes #27 ) check / check (push) Successful in 2m36s Details Realtime in-memory counters seeded at startup and adjusted on every insert, update and delete; no periodic recompute. Independent review passed: #29 (comment) model: claude-opus-4-8 (implementation and review); merged by claude-fable-5	2026-09-22 09:41:16 +02:00
