Writing a secret by hand meant knowing the active backend and its layout;
getting it wrong (a file write on an OpenBao fleet) left the value where the
resolver never reads it, so ${secret:NAME} silently degraded to the literal
<MISSING_SECRET:NAME> placeholder that a service then used as its credential.
- `castle secret {list|set|get|rm}` reads/writes the ACTIVE backend, so there's
no wrong store to pick. `set NAME` with no value reads a hidden prompt / stdin.
- `castle apply` (and --plan) now refuses to converge any deployment whose
${secret:...} refs don't resolve in the active backend: exits non-zero, writes
nothing, and names each deployment + secret + the `castle secret set` fix.
- New helpers in core/config.py: active_secret_backend(), active_backend_name(),
secret_refs(). Gate impl: deploy._unresolved_secrets() + ApplyResult.blocked.
- Tests: test_deploy_secret_gate.py, TestSecretRefs, test_secret.py. Docs: AGENTS.md.
Stacks declare host toolchains (uv/pnpm/node/hugo/deno/psql) that can drift
from what's installed and, worse, from what's on a running service's PATH.
Make those dependencies first-class and visible.
Model (core):
- stacks.ToolRequirement + StackHandler.tools declare each stack's toolchains
(command, purpose, phase, install_hint); tools_for() is the single source.
- relations synthesizes them as `kind: tool` requirements so functional?/graph
account for them; checked runtime-env-aware (run-phase tools of a systemd
service are probed against the service's PATH, not the shell) via a shared
generators.systemd.runtime_path helper the unit generator also uses, so the
checker can't drift from the generator. hint_for() makes every unmet
requirement actionable.
- stack_status: the derived per-stack health the CLI/API/UI all render.
- config: add ~/.deno/bin to USER_TOOL_PATH_DIRS so deno (supabase edge fns)
is found by services and the check, same as ~/.local/bin and the pnpm dirs.
Surfaces:
- castle stack list|info (new resource) + GET /stacks/status, /stacks/{name}
(GET /stacks stays a bare name list for the create-form select).
- castle doctor gains a "Stacks & dependencies" section (FAIL for an enabled
deployment's missing tool, WARN otherwise, unused stacks skipped).
- castle apply preflight warns (advisory, like _acme_preflight) when a tool is
missing where a service runs; ConvergePanel renders those warnings.
- Dashboard Stacks page: per-stack tool checklist with versions + copyable
install hints, program links, and verb chips.
Tests: relations (drift + hints), doctor (ok/fail/skip), /stacks endpoints.
Both machines (civil, primer) are on the current on-disk layout, so the
read-compat for older formats is dead weight. Remove it:
- config loader: only deployments/<kind>/<name>.yaml (drop flat deployments/*.yaml
and the services/+jobs/ split); drop the run.runner→manager normalizer.
- registry loader: require composite <kind>/<name> keys + manager/kind (registry.yaml
is regenerated every apply, so it's always current).
- manifest: drop the proxy/public→reach legacy input and the component→program alias
(the derived proxy/public read accessors stay). reach field defaults already match.
- config_editor: parse incoming specs directly (frontend sends the current shape).
- save_config: drop the flat-file migration cleanup.
Bootstrap seeds move to bootstrap/deployments/<kind>/ and install.sh seeds that
per-kind tree directly. The legacy→current translation for terse test fixtures
moves into each test conftest (out of production). All suites green (362).
- endpoint-level: a deployment/program edit via /config/* leaves castle.yaml
globals byte-identical (the exact regression that shipped — the endpoints were
tested but nobody asserted globals survived)
- write_program_file leaves globals untouched (core)
- /secrets/info reports the backend
Still uncovered (tracked): castle mesh CLI, direct-read refactor (dns/stacks),
backend-aware doctor, and all frontend (no test runner configured).
Root-cause hardening for the dropped-globals bug: config edits went through the
full-document save_config, which rewrote castle.yaml globals (+ every resource
file) on every deployment/program edit — so an unmodeled global (role, secrets)
was dropped.
- add write_deployment_file / write_program_file: persist ONE resource file,
never touching globals or other resources
- config_editor deployment/program save/delete/enable now use those instead of
save_config, so a deployment edit can't rewrite castle.yaml
- save_config now preserves ANY unmanaged top-level global (not just secrets)
- _aggregate_yaml surfaces role + secrets (raw-yaml round-trip completeness)
- tests: scoped write leaves globals byte-identical; unmanaged global survives
Verified live: editing lakehouse via the endpoint leaves castle.yaml unchanged.
save_config rewrites castle.yaml from scratch and only re-emitted gateway/repo/
roots — so any config save (dashboard deployment edit, config_editor) silently
STRIPPED top-level 'role' and the 'secrets:' backend block. Effect: the node
reverted to a file-backend follower, the vault stopped resolving, and a
subsequent apply baked <MISSING_SECRET> into service env (hit castle-lakehouse).
Now re-emit role (from config) + preserve the secrets block (read from the
existing file, since it's not modeled on CastleConfig). Regression test added.
- new Secrets page (/secrets, nav entry): lists vault secrets, reveal/copy,
add/edit/delete, shows active backend + addr + role; read-only on followers
- GET /secrets/info (backend/addr/role/writable); fix /secrets CRUD to use the
castle.yaml-selected backend (was defaulting to the now-empty file backend)
- OpenBaoBackend.list_names drops folder entries (node-prefix groups)
- tests: conftest forces file backend so host castle.yaml can't leak into tests
app builds clean (tsc 0); endpoints verified live against the vault.
- SecretBackend gains write/delete/list_names; FileSecretBackend + OpenBaoBackend
implement them (vault KV-v2 POST/DELETE/LIST); castle-api/secrets.py routes all
CRUD through the active backend (dashboard writes to the vault in openbao mode)
- add systemd exec_start_post (general; '-' prefix so a hook failure can't fail
the unit); castle-openbao runs an unseal.sh on boot using OPENBAO_UNSEAL_KEY
- tests: file write/read/list/delete round-trip
Verified live: write→vault→read→list→delete against OpenBao; seal→restart→
auto-unsealed. TLS hardening remains (deferred; gates cross-network/real secrets).
- secret_backends.py: SecretBackend protocol, FileSecretBackend (historical),
OpenBaoBackend (KV-v2 read + file fallback), build_backend() env-selected
- _read_secret delegates to the active backend; default is file, so production
is unchanged until CASTLE_SECRET_BACKEND=openbao
- OpenBao token bootstraps from the file backend; missing/unreachable falls back
- tests: file hit/miss, backend selection, unreachable + empty-token fallback
Read path verified live against castle-openbao. Write path, auto-unseal-on-boot,
and TLS hardening documented as remaining for full OpenBao production use.
- add static 'role' (authority|follower) to NodeConfig/CastleConfig, wired from
castle.yaml through the registry to the mesh wire; civil pinned authority
- castle-presence: TTL KV bucket each node renews (churn signal); delete-on-stop
- castle-config: authority-gated get/put + change-watch SSE (follower reconcile
hook hangs off it)
- bound the NATS drain on stop() so shutdown can't hang
- tests: role config/registry round-trip, wire round-trip, role write-gating
Single-node verified; follower reconcile pending the second node.
The `castle` CLI and the `castle-api` service are two independent in-process
drivers of `castle_core`. Each resolved DATA_DIR/REPOS_DIR at import time from
its own process env (default /data/castle), persisted nowhere — so they silently
diverged, and `apply`/dashboard-apply crashed on a non-existent /data.
Make the loaded CastleConfig the single source of truth:
- Resolve data_dir/repos_dir only in load_config (env > castle.yaml > default),
anchored to the config root; drop the DATA_DIR/REPOS_DIR module globals and the
import-time file read entirely — no global twin that can disagree with the file.
- Thread config.data_dir/repos_dir through ensure_dirs, _env_context, tls_dir_for
(now unified — deploy no longer inlines the tls path), and create/add/clone.
- ensure_dirs raises an actionable CastleDirError instead of a bare PermissionError;
the api surfaces it as 422.
- doctor: "data dir writable" check + WARN when CASTLE_DATA_DIR/REPOS_DIR env
overrides the file (the one remaining cross-process divergence vector).
- install.sh persists data_dir/repos_dir into castle.yaml (idempotent, non-default).
- Docs: registry.md globals + AGENTS.md roots.

The consumption audit only matched host:port inside a single value (a URL,
DATABASE_URL), missing the very common split-var shape (X_HOST=localhost +
X_PORT=1883, e.g. castle-api's mqtt config). Resolve those pairs too — factored
into a shared _resolve helper. A bare *_PORT with no *_HOST is ignored so a
deployment's own listen port isn't mistaken for a dependency. Adds test_audit.py.
Model:
- Drop `requires` from ProgramSpec; requires is now deployment-only.
Collapse Requirement to {ref, bind} with kind defaulting to "deployment"
(drop the unused `version`). System-package preconditions stay on the
program as `system_dependencies`, synthesized into {kind: system} for the
functional check. relations.py/deploy.py read only the deployment's requires.
- create.py seeds a stack's substrate dependency onto the deployment, not the
program. Docs + tests updated.
UI:
- Add a `requires` editor (useRequires) on service, job, and static detail
pages — edit service→service deps (ref + optional bind env var).
- Restore the gateway route table "Open" column: a kind-aware in-app link to
each route's deployment.
- Reformat the reach control: name baked into each option
(localhost:PORT (local) / <name>.<domain> (internal) / <name>.<pubdomain> (public)).
- Services page: sort statics in with systemd services by name, add a
search + kind-filter bar mirroring the programs page.
A deployment's identity becomes (name, kind), so a tool, service, and job can
share a name (a `backup` trio). Kind is structural — which per-kind store / dir —
not a derived discriminator threaded around.
- CastleConfig holds per-kind stores (services/jobs/tools/statics/references);
all_deployments()/deployments_named()/deployment(kind,name) replace the single
flat `deployments` dict. A construction-only `deployments` InitVar routes a flat
map into the stores by kind_for.
- Storage: deployments/<store>/<name>.yaml (per-kind dirs), with read-compat for
the old flat + services/+jobs/ layouts.
- Registry keyed by composite "<kind>/<name>" + name field; get()/all()/named()/put().
- Job units carry a -job marker (castle-<name>-job.{service,timer}); services and
everything else unchanged — so a service and a job can coexist.
- deploy/apply/lifecycle thread kind through unit naming, activate/deactivate,
is_active; caddyfile/tunnel/relations iterate via all_deployments/registry.all.
- Subdomain uniqueness validated across kinds (a service and a static can't share one).
182 core tests pass, incl. a new same-name-trio suite (round-trip, distinct units,
subdomain guard). API/CLI/UI updated in follow-up phases.
Deployment/program edits could silently drop spec fields:
- GET /deployments/{name} served the runtime view (no reach/program/root/expose)
for deployed deployments, so the dashboard round-tripped a lossy manifest and
stripped fields on save (broke astro). Now serves the editable castle.yaml spec
when the deployment is in config.
- _save_deployment and save_program replaced the whole object with client input.
Now shallow-merge over the existing spec (omit = preserve, null = clear), so a
partial/lossy save can't drop untouched fields.
- save_yaml rebuilt GatewayConfig from `port` only, wiping tls/domain/tunnel/
cert_hook on a whole-file save. Now uses a shared parse_gateway() (also used by
load_config) so gateway fields can't drift between the two.
Dashboard forms (ServiceFields/StaticFields) send explicit null to clear, per the
merge contract; adds exposure host-label helpers. Coverage: detail-serves-spec,
save round-trip, partial-patch-preserves, null-clears, program partial-patch,
parse_gateway, and config save/load round-trip.
Frontend builds triggered from the castle web app run inside the castle-api
systemd service, whose PATH omits nvm's versioned node dir — so `pnpm build`
died with `node: not found` even though it worked from an interactive shell.
Introduce a per-program node convention: a program declares its version the
ecosystem-standard way (.node-version / .nvmrc / package.json engines.node),
and castle_core.toolchains.resolve_node_bin() maps it to a concrete nvm bin dir
(CASTLE_NODE_VERSIONS_DIR, default ~/.nvm/versions/node; newest match wins).
The same resolver feeds both sites that run a program's node:
- build time: stacks._build_env() prepends the pinned node for the dev-verb
subprocess (keyed on the source dir), so `castle program build` uses the
program's node regardless of caller.
- run time: deploy._build_deployed() stores it in Deployment.path_prepend,
which the systemd generator puts ahead of the default unit PATH — so a
`launcher: node` service runs its program's node.
A pinned-but-uninstalled version fails loud with an `nvm install` hint instead
of a cryptic `node: not found`. Unpinned → no injection (no guessing).
Also: the systemd generator now honors an explicit PATH in defaults.env as a
full override instead of clobbering it with a trailing Environment=PATH line
(systemd's last-assignment-wins rule had silently defeated the documented
escape hatch).
Pins app/.node-version and documents the convention in the react-vite stack.

`system_dependencies` holds apt PACKAGE names; checking `which <name>` only
coincides with "installed" when the name equals its command (pandoc, rsync). Names
like poppler-utils / texlive-latex-base / docker-compose-plugin have no binary of
that name, so the functional? predicate wrongly reported them unmet. Fall back to
`dpkg -s` (the real "installed" check) after the PATH fast-path.
A derived, mostly-computed model of how programs, deployments, and repos relate,
plus the git-sync surfaces that motivated it. See docs/relationships.md.
Core:
- `requires: [{kind, ref, version?, bind?}]` on programs + deployments — one
precondition relation; `system_dependencies` is its `{kind: system}` alias.
kind fixes meaning + check (system=installed, deployment=exists).
- relations.py: derives repos (git toplevel / monorepo), fan-in, and the
predicates functional?/fresh?/deployed? — nothing stored.
- env is generated FROM a `{kind: deployment, bind}` requirement (target URL →
consumer env), never scraped back into one; explicit defaults.env still wins.
- git.py: working-copy status/pull, repo toplevel + remote url.
Surfaces:
- `castle graph` + GET /graph — the relationship diagnostic.
- GET /repos, /repos/{key}/git|sync — repo-scoped sync (a repo is the sync unit;
a monorepo backs several programs). GET /programs/{name}/git|sync + repo context.
- Dashboard: Graph screen, program-page git status + repo-aware Sync, and a
monorepo banner on Programs.
Governing principle: predicates are derived; encode only the non-derivable, as a
node or edge property. Pull-only sync — converge stays a separate step.
Expose raw-TCP services (postgres) by name at <name>.<domain>:<port> and
cut the gateway's ACME wildcard cert onto them so they present a trusted
cert. Replaces the proxy/public booleans with a single `reach` enum
(off|internal|public); legacy input still parses via derived accessors.
Core:
- expose.tcp{port,tls} + TlsSpec(material: pair|combined|off, reload)
- tls.py: materialize cert files from Caddy's wildcard, reconcile on
renewal; `castle tls` CLI; optional cert_obtained events-exec hook
(gateway.cert_hook, gated so a plugin-less Caddy still parses)
- apply waits (bounded) for the wildcard to issue before materializing so
a fresh-node TLS service starts with its cert in place, then scopes
materialization to the deployments being applied
- reach: internal|public requires an expose block (no silent no-op);
public raw-TCP guarded until tunnel support lands
- chain.pem (${tls_ca}) is the issuer chain (leaf stripped), a real CA
bundle distinct from cert.pem
- one shared ${...} resolver (resolve_placeholders) for env and container
run fields; run.env now expands like volumes/args; $$ escapes a literal
- validate the generated Caddyfile before reloading the gateway so an
invalid config never degrades routing
Docs: docs/tcp-exposure.md. Tests cover reach/expose validation,
placeholder expansion + escape, issuer-chain material, TLS materialize.
Reconcile the running system to declared config in a single operation,
replacing the old deploy && start plus the per-kind enable/disable/
install/uninstall verbs. The mechanism varies by manager (systemd unit /
PATH install / gateway route); the verb never does.
Core (castle_core.deploy.apply):
- render (units, Caddyfile, tunnel) then reconcile: activate every
enabled deployment that's down, restart any whose unit bytes changed,
deactivate the disabled ones. Returns ApplyResult (the enacted diff).
- --plan computes the diff and touches nothing.
- restart-on-change is exact: _render_unit_files is the single source of
truth for unit bytes, used both to write units and to predict restarts,
so the plan can't drift from what deploy writes.
Desired state:
- DeploymentBase.enabled (default True) — the declarative on/off. apply
converges to it; a disabled deployment is defined but not running and
gets no gateway route (else it would 502). Registry omits enabled when
True, keeping existing registries byte-identical.
CLI:
- add `castle apply [name] [--plan]`; keep `restart` as the one
imperative bounce, plus status/doctor/logs/gateway/program.
- retire deploy, start, stop (top-level); service/job deploy|enable|
disable|start|stop; tool install|uninstall; program install|uninstall.
- next-step strings + doctor hints now say `castle apply`.
Verified: core 129 + cli 31 green; live `castle apply` on a converged
node reports "nothing to do" with no spurious restarts; --plan shows an
empty diff; gateway + api stay up.
A program has no single kind — it HAS deployments, each with its own kind (a
program can be a tool AND a job, e.g. protonmail). Remove program-level kind:
- core: drop ProgramSpec.kind; CastleConfig.kind_of → deployments_of(name) →
[(deployment-name, kind)]; tools property derives from a tool deployment.
- api: ProgramSummary drops kind/services/jobs → deployments: [{name, kind}];
/programs?kind= filters by deployment-kind membership; a program's legacy
DeploymentSummary carries kind=None.
- cli: list/info show a program's set of deployment kinds; --kind filters by
membership.
Also: Services page now covers statics — /services returns kind in
{service, static} (both are exposed, URL-reachable 'services', caddy vs systemd),
and ServiceSummary gains kind + manager to distinguish them.
Suites: core 124, cli 25, castle-api 58.
Replace the conflated `runner` axis with two orthogonal ones: `manager`
(systemd|caddy|path|none) — who supervises/realizes a deployment — and, for
systemd only, a nested `launcher` (python|command|container|compose|node) — how
the process starts. ServiceSpec and JobSpec collapse into one manager-
discriminated DeploymentSpec union (Systemd/Caddy/Path/Remote); the services/
and jobs/ config dirs collapse into one deployments/ dir. The human "kind"
(service|job|tool|static|reference) is fully derived (kind_for), never stored —
the frontend kind is renamed static. behavior is gone.
- core: DeploymentSpec union + LaunchSpec + kind_for; legacy-aware loader
normalizes old runner shapes; CastleConfig.deployments with derived
services/jobs/tools views; registry.Deployment carries manager/launcher/kind.
- cli: service/job/tool as filtered views + a deployment group; --behavior→--kind,
create --runner→--launcher; lifecycle dispatches over config.deployments.
- castle-api: /deployments primary with /services,/jobs as views; summaries
derive kind; PUT/DELETE /config/deployments/{name} (services/jobs aliased).
- app: KindBadge, frontend→static everywhere, pick-a-kind creation wizard,
per-kind config editors.
- docs: single deployments/ layout, manager/launcher, static kind throughout.
Live migration verified byte-identical: regenerated Caddyfile and every unit
ExecStart line unchanged, so nothing restarted. Suites: core 124, cli 25,
castle-api 55; dashboard build + type-check clean.
- A static service is inherently exposed, so `public: true` no longer trips the
"requires proxy" validator — frontends can be public via the tunnel for free
(the original friction that started this refactor, now resolved).
- docs/registry.md: the manager model (systemd/caddy/path/none), the runner→manager
table incl. static/path, and behavior as a derived display label.
- manifest: RunPath (runner: path) — a CLI on PATH via `uv tool install`, manager
= path, no unit/route (like remote/static).
- lifecycle/service: a path deployment's start/stop = install/uninstall (routed
through activate/deactivate, which skip the reinstall when already on PATH).
`castle service start/stop <tool>` and status now dispatch by manager; status
shows the manager tag [systemd|caddy|path|none].
- config.tools() now derives from `runner: path` services, not the behavior label.
- castle-api: the "installed" flag derives from manager==path, not behavior==tool.
- create: a python-cli stack emits a `runner: path` service.
`behavior` no longer drives any runtime logic — it survives only as a display
label + `list --behavior` filter. Verified live: html2text uninstall→reinstall
round-trip via `castle service stop/start`.
- manifest: `manager_for(runner)` — the single source of truth mapping a runner to
its manager (systemd | caddy | path | none). deploy's `managed` now derives from it.
- lifecycle: is_active/activate/deactivate dispatch by manager instead of behavior
(removed the stale `_is_static_frontend`, which broke once frontends became
services). caddy → gateway reload; path → install/uninstall; none → no-op.
- cli/service: start/stop/restart and enable/disable route through the manager
(systemctl only for systemd; static reloads the gateway; remote is a no-op);
platform restart skips non-systemd runners.
- create: a frontend stack (react-vite/supabase) now emits a `runner: static`
service, not a bare frontend program.
Two features built this session, committed together as a checkpoint before the
deployment-model refactor (they share files, so kept as one rollback point):
- Public exposure via Cloudflare tunnel: a `public` toggle on services (requires
proxy), gateway.public_domain/tunnel_id config, a cloudflared ingress generator
(generators/tunnel.py) that maps <name>.<public_domain> to the gateway's
internal host, deploy wiring, and docs/tunnel-setup.md.
- Frontends as `static`-runner services: a RunStatic runner served by Caddy
(file_server), no systemd unit (like `remote`); the Caddyfile generator now
derives static routes from services instead of a behavior==frontend branch.
CaddySpec had only `enable` left (path_prefix/host removed; extra_snippets was
unused), so `proxy: { caddy: {} }` was three levels of nesting for a checkbox —
and it invited drift (supabase silently reverted to proxy.caddy.host). Replace it
with a plain `ServiceSpec.proxy: bool`.
- Model: remove ProxySpec/CaddySpec; `proxy: bool = False`. Readers simplified to
`bool(svc.proxy)` (generator, castle-api summaries, CLI info).
- CLI create / dashboard editor + create form: write `proxy: true` / a checkbox.
- Configs migrated to `proxy: true` (and supabase's stale proxy.caddy.host block
removed).
- Docs (registry, dns-and-tls, design, stack guides) + tests/fixtures updated;
also fixed lingering path-model staleness in the stack guides.
The dashboard is now served at castle.<domain> (was castle-app.<domain>). Since
the subdomain is the program name, this is just a program rename plus the one
special-case constant.
- Generator: _DASHBOARD = "castle" (the :9000 redirect target and off-mode root).
- Program file renamed (runtime): programs/castle-app.yaml -> programs/castle.yaml
(source unchanged: repo:app).
- Dashboard UI: ProgramDetail shows a frontend's subdomain (via subdomainUrl),
dropping the old castle-app-at-root special-case; comment refs updated.
- Docs: registry.md/design.md/react-vite.md updated to the subdomain model and the
`castle` name (react-vite.md also corrected — frontends serve at their subdomain
root with VITE_BASE=/, and builds are manual via `castle program build`, not
deploy).
Collapse the two proxy shapes (path_prefix + host) to a single checkbox: a
service is either port-only, or exposed at <service-name>.<gateway.domain>. Path
routes and their prefix-stripping foot-guns are gone; the subdomain is always the
service name (rename the service to change it).
- Schema: CaddySpec is just `enable` (presence = expose). service_proxy_targets
returns (expose, port, base_url); Deployment carries `subdomain` (was
proxy_path/proxy_host). Registry/deploy/mesh/CLI updated in lockstep.
- Generator: compute_routes emits one host route per exposed service/frontend
(address = name). acme mode = one *.<domain> site with a reverse_proxy matcher
per service + a file_server matcher per frontend; the :<port> site redirects to
the dashboard. off mode = a HTTP control plane on :<port> (dashboard at / +
/api → castle-api); other services are port-only.
- Dashboard/API: castle-app and castle-api are ordinary subdomains. The dashboard
derives the API base at runtime (castle-api.<domain> on a subdomain, else /api)
and calls it cross-origin — castle-api already allows CORS *. Frontends build
with VITE_BASE=/ (served at their subdomain root).
- CLI: `service create` drops --path/--host; --no-proxy makes it port-only.
- Docs/tests reworked for the model; docs use generic placeholders only (no
personal host/domain/IP details).
acme mode fully replaced the internal-CA path (which required installing a private
CA on every device — the exact pain, esp. on Android, that acme avoids). Remove
`internal` entirely and simplify how services declare host routes.
- Generator (caddyfile.py): drop the `tls internal` branch — modes are now
`off` | `acme`. In acme mode the published subdomain is the **first DNS label**
of `proxy.caddy.host` (a bare `claw`, or a legacy `claw.civil.lan`, both →
`claw.<domain>`), so services stay domain-agnostic and the declared value is
authoritative again (no more silent service-name override). Shared
`_host_matcher_block` reused by off-mode and the acme wildcard site.
- castle-api: delete `GET /gateway/ca.crt`, `_gateway_ca_pem`, `_ca_fingerprint`
and the now-unused imports; drop `ca_fingerprint` from `GatewayInfo` (keep
`tls`).
- Dashboard: remove the CA-cert download button + unused imports; drop
`ca_fingerprint` from the `GatewayInfo` type.
- Tests: replace TestCaddyfileTlsInternal with an off-mode class (keeps the
runner-agnostic host-route coverage); acme tests assert first-label derivation
incl. label-wins-over-service-name; drop the castle-api CA-endpoint test.
- Docs: registry.md + dns-and-tls.md — two-mode tables (off|acme), remove the
internal sections/CA-download, document the bare-label host convention; note a
domain-less node stays on `off`.
internal-CA HTTPS forces every device to trust a private root, which breaks down
on some clients (Android browsers). acme mode instead obtains a real Let's Encrypt
wildcard cert (*.<domain>) via a DNS-01 challenge, so browsers trust it with zero
CA install — while services stay internal-only (no inbound exposure, no public A
records; only a transient _acme-challenge TXT touches the public zone, and LAN DNS
resolves the names to a private IP).
- Config: GatewayConfig/NodeConfig gain domain, acme_email, acme_dns_provider
(plumbed through load/save + registry + deploy, omitted-when-empty for
round-trip stability). tls stays the discriminator: off | internal | acme.
- Caddyfile generator: acme branch emits a global {email, acme_dns <provider>
{env.TOKEN}} block + one *.<domain> wildcard site with host matchers derived
from the service name (<name>.<domain>); path/static stay on :<port>. Shared
_host_matcher_block helper (reused by off-mode). CASTLE_ACME_STAGING=1 toggles
the LE staging CA; acme-without-domain falls back to HTTP with a warning.
- deploy(): _acme_preflight warns (never writes) when domain, the gateway-service
token env, or the CLOUDFLARE_API_TOKEN secret is missing.
- install.sh: opt-in --with-dns-plugin[=provider] builds a DNS-plugin Caddy via
xcaddy (pinned) to /usr/local/bin/caddy, which the gateway picks up on deploy.
- Tests: TestCaddyfileTlsAcme (global block, wildcard site, derived host matcher,
path routes on :port, staging toggle, no-domain fallback). Docs: gateway.tls
modes table + full acme/DNS-01 section (setup, wild-central LAN DNS, staging).
Adds "a stack whose default is a substrate": a shared self-hosted Supabase
backend plus a `--stack supabase` that scaffolds per-app projects (migrations +
edge functions + static UI) which deploy against it. Apps own their code and
stay repo-durable; only their rows/blobs live on the shared substrate.
- compose runner: new RunCompose supervises a multi-container stack as one
systemd unit (ExecStart=`compose up`, generated ExecStop=`compose down`);
secrets via EnvironmentFile. Reusable beyond Supabase. Deployment.stop_cmd
carries the teardown command through the registry.
- supabase stack: CLI --stack choice, STACK_DEFAULTS→frontend with
build.outputs=[public], _scaffold_supabase() (migrations/RLS/functions/
static UI/app manifest), and SupabaseHandler with a forward-only idempotent

The gateway was HTTP-only by design, but a plain-HTTP origin is not a browser
"secure context", so apps that need WebCrypto (device identity, E2E crypto)
can't run when proxied — only localhost or HTTPS qualifies.
Add an opt-in `gateway.tls: internal`. When set, each host route
(proxy.caddy.host) is emitted as its own `<host> { tls internal; reverse_proxy }`
site, served over HTTPS by Caddy's local CA (Caddy binds :443 and redirects :80).
Path-prefix/static routes stay on the HTTP :<port> site — give a service a host
route to put it on HTTPS. Default (unset/off) keeps the existing HTTP-only
Caddyfile (single :<port> block, auto_https off, host matchers inline).
Plumbing mirrors gateway_port: GatewayConfig.tls (castle.yaml load/save) →
NodeConfig.gateway_tls (registry load/save, set in deploy) → the Caddyfile
generator. Tests cover both modes; docs/registry.md documents the option plus
the two operational requirements (binding 443/80 via the unprivileged-port
sysctl, and trusting Caddy's root CA on clients) and the host-route-vs-prefix
guidance that motivates it.
Editing a service's routing (port, path_prefix, host) and then hitting
"apply" or "gateway reload" — rather than a full deploy — left the running
Caddyfile reflecting the old routing. The Caddyfile was generated from the
derived registry.yaml snapshot, which only `deploy()` rebuilds from
castle.yaml; apply/reload regenerated from that stale snapshot.
Make castle.yaml the single source of truth for local routes:
- caddyfile.py: new shared `service_proxy_targets()` derives a service's
(proxy_path, proxy_host, port, base_url) from its spec. `compute_routes`
now builds local routes from `config.services` when castle.yaml is
loadable, falling back to `registry.deployed` only when it isn't. Since
deploy/apply/reload all funnel through `compute_routes`, every regeneration
path now tracks the spec. Mesh/remote and static-frontend routes unchanged.
- deploy.py: `_build_deployed_service` uses the same shared deriver, so the
written registry and the computed routes can't diverge.
- config_editor.py: `/config/apply` now runs a full `deploy()` (rebuilding
units + Caddyfile and reloading the gateway) before restarting services, so
changed unit ExecStarts actually take effect. Scheduled jobs are no longer
restarted on apply. Drops the now-unused direct caddy-reload path.
- Regression tests: a stale registry's old port/path loses to castle.yaml;
registry fallback still works when config is unavailable.
- Introduced `_write_castle_config` function to scatter nested config into separate YAML files for programs, services, and jobs.
- Updated `castle_root` fixture to utilize the new config writing method.
- Added tests for configuration aggregation and scattering in `test_health.py`.
- Removed legacy unit handling from `manifest.py` and refactored related code in `config.py`.
- Updated documentation to reflect new configuration directory structure.
- Removed obsolete unit tests related to unit expansion.
A python-runner service ran from a tool venv (uv tool install --editable),
separate from the project venv that uv sync manages. The editable link kept
source live, but dependencies were resolved independently in each venv, so a
new dependency landed in the project venv and never reached the running
service — leaving no clean rollout for it.
Deploy now emits ExecStart=uv run --project <source> --no-dev <program>,
running the service in place from its own project venv. uv run syncs the env
to the lockfile before launching, so a single restart picks up both code and
dependency changes; the ExecStart is deterministic from source and never goes
stale. The tool-venv install is gated to the command runner only; uv tool
install is reserved for tool-behavior programs, where PATH is the point. A
python service with no resolvable source falls back to a PATH lookup.
Driven by adopting lakehouse (an existing daemon that bundles its own SPA) —
see docs/findings-lakehouse.md.
#3 deploy reloads the gateway. castle deploy regenerated the Caddyfile but
left the running Caddy on the old config, so new proxy routes were silently
dead. Deploy now reloads the gateway when it's running.
#1 castle expose <program>. Turns an adopted program into a service
(run/port/health/proxy/systemd) in one command — the missing
daemon-to-service step. Flags: --port --health --path --run --port-env
--host --no-proxy.
#2 port_env mapping. A service can declare expose.http.internal.port_env so
castle sets the env var the program actually reads (e.g. lakehoused reads
LAKEHOUSED_DAEMON_PORT, not castle's convention LAKEHOUSE_PORT). Castle now
genuinely drives an adopted daemon's bind port.
#4a auto-base for react-vite. The build passes VITE_BASE = the gateway serve
prefix (/<name>/, or / for castle-app); vite.config reads it. A castle-built
frontend now works at its subpath with no hand-tuned base. castle-app's
vite.config updated as the reference.
#4b host-based routing. proxy.caddy.host routes a whole hostname to the backend
root via a host matcher inside the :9000 site, so a root-based SPA (base="/")
serves unchanged — the fix for proxying an app castle can't rebuild. Caddyfile
now emits 'auto_https off' (HTTP-only gateway on a non-standard port).
Nit: activate skips the editable reinstall when the tool is already on PATH.
Tests: core 94, cli 24, api 52; ruff + app build clean. Verified live: lakehouse
runs under systemd, API at /lakehouse, full UI (SPA boots) via host routing.
The Caddyfile generator now emits static-frontend routes that root directly at
<source>/<build.outputs[0]> (e.g. /data/repos/castle/app/dist) instead of a copy
under ~/.castle/artifacts/content. Removes _copy_app_static and the central
content-dir staging entirely; rebuilds are live without a copy step.
- caddyfile.py: manifest-driven static routes (castle-app at /, others at /<name>)
- ReactViteHandler.install just builds in place (no copy); uninstall is a no-op
- is_active(static frontend) = repo dist exists
- test isolation updated for the generator's config use
Dashboard + power-graph-app verified serving from repo dist; 168 tests pass.
Convergent deploy (prefix-based prune): castle deploy now removes orphaned
castle-* systemd units/timers no longer in the registry. Full deploy only;
partial (--name) deploys preserve siblings. Fixes the orphaned-timer / stale-
path drift class.
Container runner: derive --name from the service name (castle-<name>) instead
of the image name; skip the <PREFIX>_DATA_DIR env injection for containers
(avoids colliding with image env namespaces like NEO4J_*).
Unified active lifecycle (core/lifecycle.py): install/uninstall keep their
names but become activate/deactivate, dispatching by behavior — tool→PATH,
daemon/self-serving-frontend/job→systemd, static frontend→served. is_active
reports a uniform state (PATH-independent for tools). The CLI install/uninstall
and service enable/disable route through the extracted core.
API + dashboard: surface a uniform `active` state on programs alongside
`installed`; ProgramDetail shows active/inactive.
Tests: test_deploy_prune (6), test_lifecycle (5). 168 tests pass; lint clean.
