Two ways: the compose stack, or by hand. The hand-rolled path is what this was developed against and is what the compose file encodes, so it is written down first — a run book that stays true even if the images are never built.
What the stack is
| piece | role | state |
|---|---|---|
| zit | the store. quarry shells out to it for every read and write (0001 §2) | the .zit files themselves |
| quarry | the forge: indexes, UI, API, sync fronting | derived indexes, embedded NATS, OLTP database |
| notify | notifications: workflows, subscribers, topics, the inbox quarry embeds | SQLite |
| dagnats | the workflow engine notify runs on: embedded NATS + JetStream + an HTTP bridge | JetStream data |
zit is not a runtime dependency in the ordinary sense — it is quarry's
only store interface, so its version is part of quarry's behaviour.
On 2026-08-16 three zit builds changed what quarry does: frames got
31% faster, a card-parsing fix changed which artifacts parse at all (and
until it landed, sqlite's 794 tickets were invisible), and a new
stat -R let quarry serve a bare store. Pin the pair; do not let a
deploy resolve zit from whatever is on PATH.
By hand
dagnats
Runs under launchd on this machine as com.dmestas.dagnats, binding
NATS on 4222 and its bridge on 8080, with data in
~/Library/Application Support/dagnats.
launchctl kickstart -k gui/$(id -u)/com.dmestas.dagnats
A freshly-built Go binary replacing it must be ad-hoc signed or
launchd kills it with OS_REASON_CODESIGNING and the service silently
fails to come back:
go build -o ~/go/bin/dagnats ./cmd/dagnats
codesign -s - -f ~/go/bin/dagnats
launchctl kickstart -k gui/$(id -u)/com.dmestas.dagnats
In standalone mode dagnats binds loopback, which is why anything talking to it shares its network namespace under compose rather than reaching it by service name.
notify
notify bootstrap -dev -db notify.db -org quarry -env dev # prints apiKey once
notify serve -dev -db notify.db -addr 127.0.0.1:3000 \
-nats-url nats://127.0.0.1:4222 -bridge-url http://127.0.0.1:8080
curl -s localhost:3000/readyz # {"status":"ok","bridge":true,"db":true}
-dev derives a fixed, publicly-known master key. Outside development
set NOTIFY_MASTER_KEY_HEX.
Quarry triggers two workflows by name, so they must exist, each with an
in_app step or nothing reaches an inbox:
K=<apiKey>
for wf in quarry-activity quarry-mention; do
curl -s -X POST localhost:3000/v1/workflows -H "Authorization: ApiKey $K" \
-H 'Content-Type: application/json' -d "{
\"name\":\"$wf\",\"triggerIdentifier\":\"$wf\",
\"steps\":[{\"stepId\":\"S1\",\"type\":\"in_app\",
\"controlValues\":{\"subject\":\"{{payload.summary}}\",
\"body\":\"{{payload.repo}} — by {{payload.actor}}\"}}]}"
done
Activity is addressed to a topic, mentions to a person. A repository's
activity goes to the topic repo-<name> (quarry sanitizes its own
repo:<name> convention, because notify accepts only lowercase letters,
digits, hyphens and underscores in a key and rejects the whole trigger
otherwise). A topic with no members notifies nobody, so subscribing is a
required step, not a nicety:
curl -s -X POST localhost:3000/v1/subscribers -H "Authorization: ApiKey $K" \
-H 'Content-Type: application/json' -d '{"subscriberId":"you"}'
curl -s -X POST localhost:3000/v1/topics -H "Authorization: ApiKey $K" \
-H 'Content-Type: application/json' -d '{"key":"repo-synthetic","name":"synthetic activity"}'
curl -s -X POST localhost:3000/v1/topics/repo-synthetic/subscribers \
-H "Authorization: ApiKey $K" -H 'Content-Type: application/json' \
-d '{"subscriberId":"you"}'
quarry
quarry serve --addr 127.0.0.1:8950 --data ./data \
--notify http://127.0.0.1:3000 --notify-key "$K" \
--repo quarry=$HOME/quarry
--data is not optional in practice: it defaults to .quarry beside the
first --repo, which writes derived state into whichever repository
happens to be listed first. Always pass it.
Gates are open until they are closed, and closing them is two separate credentials on purpose — accounts are the forge identity (argon2id), the sync secret is the RFC §6.3 value the protocol fixes:
quarry account add --user you --admin --data ./data # closes web/API writes
quarry user add --repo name=$HOME/quarry --user you --data ./data # closes push
The account gate is global: the first account closes writes on every repository in the fleet, not just one.
Fleet admin
/fleet is the operator page — every store's ingest health, and the
upstreams it mirrors. It is site admin only: admin on one repository
is not enough, because the page reports operational detail across the
whole fleet and can force writes into any of it.
Health is per-process. Total and Fallbacks count what THIS server
has ingested since it started, so a restart with a warm index reports
zero of both however much the store holds. The parse-fallback number
worth looking at is the one a quarry reindex produces.
Mirroring
A mirrored store tracks an upstream: quarry pulls, and never pushes.
curl -u you:pw -X POST http://localhost:8080/api/v1/mirrors \
-H 'Content-Type: application/json' \
-d '{"repo":"fossil","url":"https://fossil-scm.org/home","every":3600}'
every is seconds and is floored at 60 — these upstreams are other
people's servers, and the floor is a courtesy the configuration surface
cannot opt out of. --mirror-tick (default 1m) is how often due-ness is
evaluated, not how often anything is pulled.
Pulls take the store's single-writer lease, so mirroring is safe with more than one node serving the same store. A pull that brings nothing new does not trigger a re-index and is not logged; almost every one is quiet, and a line per store per interval buries the ones that matter.
Two limits worth knowing before you rely on it:
- The store needs a working checkout.
zit pullrefuses-Rand operates on a working directory, so a genuinely bare store cannot be mirrored. Stores created byzit cloneorzit import-fossilcarry one, so this bites only hand-built bare stores. - The upstream must allow anonymous clone. Some Fossil servers serve
a browsable timeline while refusing sync —
sqlite.org/lemonis one. Note thatfossil cloneexits 0 on that refusal, so check for the repository, not the exit status.
With compose
export NOTIFY_SRC=../notify # a notify checkout; it builds dagnats too
export ZIT_REF=<commit> # pin the store implementation
docker compose up --build
Then bootstrap notify once (docker compose run --rm notify bootstrap …),
put the key in QUARRY_NOTIFY_KEY, and create the workflows and topics
as above.
docker run <image> cat /etc/quarry-build reports which quarry and which
zit an image carries, without starting it.
Unverified.
Dockerfileandcompose.ymlhave not been built — no container runtime is installed on the development machine. The two build recipes inside them are verified natively: zit compiles from a clean clone of the GitHub mirror withzig build --release=fast, and quarry builds fully static withCGO_ENABLED=0(its SQLite is WASM-based and Pikchr runs on wazero, so nothing needs a C toolchain). What remains untested is the image assembly and the compose wiring.
Ports
| port | what |
|---|---|
| 4222 | dagnats NATS |
| 8080 | dagnats HTTP bridge (and its console — unauthenticated, keep it on loopback) |
| 3000 | notify API |
| 8950 | quarry |
quarry's own embedded NATS binds nothing (DontListen), so it never
collides.
