- service/static/tool/job detail pages now link back to their program;
backfill the program ref on registry-only static+job details (the
registry Deployment carries no program ref).
- new RelatedDeployments card surfaces a deployment's requires edges both
directions (Depends on / Required by) as links; references render inert.
- replace the service detail Subdomain/Served-at rows with a launch icon
in the header that opens the gateway URL in a new tab.
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.
API: /config/{services,jobs,tools,static}/{name} now pin the twin they
target — _save_deployment/_delete_deployment take an explicit kind so a
patch to a 'backup' service can't bleed into a 'backup' job/tool. Add
/tools and /static endpoints; keep /deployments/{name} kind-agnostic.
New test_kind_twins proves per-kind save/delete isolation on disk.
UI: ConfigPanel and CreateDeploymentForm write to the kind-scoped
resource; GatewayPanel/NodeDetail/DeploymentsSection link via a shared
detailPath(name, kind) helper instead of the ambiguous /deployment/:name.
Includes incidental ruff-format reflow of untouched api files.
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.
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.
Rework the dashboard around convergence:
- ServiceControls / ServiceCard / JobCard: replace start/restart/stop
with a Power toggle (set enabled → apply, i.e. activate/deactivate)
plus Restart (the one imperative bounce).
- ToolDetail: install/uninstall becomes an Enable/Disable toggle;
`installed` stays the live state, `enabled` the desired one.
- ConfigPanel Apply and CreateDeploymentForm now POST /apply (one
converge that renders + restarts only what changed) instead of
/deploy + a separate start/restart.
- New ConvergePanel on Overview: a terraform-style Preview (POST /apply
plan=true) showing would-activate/restart/deactivate, then Apply.
- useApply + useSetEnabled hooks; `enabled` added to Service/Job/
Deployment types; both handle the self-restart connection drop.
Backend: PUT /config/deployments/{name}/enabled sets desired on/off
(edit config; caller runs apply) — the declarative toggle the UI uses.
Dashboard builds clean (tsc + vite); 59 API tests pass; live /apply and
/services?enabled verified after an api restart.
The field showing a deployment's launcher + target is now labelled 'Launch'
(consistent with launcher/manager vocabulary) on ServiceDetail and the Service/
Job/Create field editors.
- Nav: Services/Scheduled/Tools nested under a 'Deployments' group (expandable;
flattened to icons when the sidebar is collapsed). Programs stays top-level.
- Overview: Tools tile (Wrench, count of tool programs).
- New /tools/:name tool detail page (useDeployment): Install/Uninstall lifecycle,
a link up to its program, and an editable ToolFields (description + env).
- ServiceDetail is static-aware: a caddy deployment shows served-by-gateway +
URL + root, no start/stop, and edits via a new StaticFields (root + public + env)
so a launcher is never injected into a caddy deployment.
- Program detail's Deployment section is now a clean list of links — every
deployment (tool→/tools, service/static→/services, job→/jobs) links to its
detail page; lifecycle controls moved onto those pages.
clean pnpm build + tsc.
- Programs page: each card lists the program's deployments (name · kind) instead
of a single kind badge; kind-filter chips removed (nav is the kind lens now).
protonmail honestly shows tool + job.
- New Tools nav page (Wrench) — programs with a tool deployment (/programs?kind=tool).
- Services page now shows statics too: /services returns service + static, and a
static renders as a caddy-served card (KindBadge, served URL, no start/stop).
- Program detail: DeploymentsSection + deleteConfirm rebuilt over program.deployments;
header drops the (now nonexistent) program kind.
- ServiceFields / JobFields: launcher is now an editable select (python|command|
container|compose|node), persisted into run.launcher via the normal save.
clean pnpm build + tsc --noEmit.
- /services was returning every non-job deployment (tools, statics, remotes);
filter it to kind==service so the Services page shows only services.
- Programs page gains kind-filter chips (All / Service / Job / Tool / Static /
Reference) with per-kind counts, colored to match KindBadge.
- Replace window.confirm with a reusable ConfirmModal (styled, danger variant,
Esc/Enter, preserves bulleted bodies); FormFooter's delete uses it, so program/
service/job deletion now confirms in-app with the enumerated cascade list.
castle-api 58 passed; /services live drops from 37 to 15 (services only).
The confirm dialog (window.confirm in FormFooter) now spells out exactly what
cascade will do — uninstall the tool from PATH / drop the static route / stop,
disable and remove named service+job deployments, and remove the catalog entry —
each as its own bullet, ending with the reassurance that source on disk is kept.
A program and its 1:1 tool/static deployment are one thing to the user, so
'Delete program' now just works instead of refusing. DELETE /config/programs/
{name}?cascade=true tears down each referencing deployment (manager-aware:
uninstall a tool from PATH, stop+disable a service/job, drop a static route),
removes them and the program, then converges the runtime (prune orphan units,
regenerate the Caddyfile, reload the gateway). Without cascade it still 409s
(safe API default). The dashboard drops the 'can't remove while deployed' block,
labels the action 'Delete program', and the confirm names exactly what will go.
Verified live: throwaway tool → cascade delete removes program + path deployment,
real config untouched; plain delete of a referenced program still 409s.
castle-api 57 passed.
Install/Uninstall no longer live in the program's action cluster (they were a
tool's PATH-deployment lifecycle masquerading as a program action). ProgramActions
is now dev-verbs-only (build/test/lint/type-check/check). The program detail's
Deployment section owns lifecycle, keyed on kind: a tool shows Installed-on-PATH
with an Install/Uninstall toggle, a static shows served-by-gateway + its URL,
services/jobs link to their own pages. Program list cards drop the quick toggle
for a plain active dot. 'Remove program' stays as catalog deletion — no longer a
dead-end now that the blocking deployment is visible in the Deployment section.
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.
- Gateway route table: a public route's address now links to its public URL
(green, with the tunnel icon) instead of the internal one.
- Program detail: remove the editable `behavior` selector — behavior is a derived
label now and drives no logic, so editing it was meaningless (the stored value
is preserved on save via the manifest spread).
The dashboard's stack dropdown hardcoded its options (python-cli/fastapi/
react-vite), so a supabase program showed "(none)" — the value had no matching
option. Make the backend the single source of truth instead:
- core: available_stacks() returns sorted(HANDLERS) — the stacks castle has
handlers for.
- castle-api: GET /stacks exposes it.
- cli: --stack choices derive from available_stacks() (drops the duplicated list).
- app: ProgramFields fetches /stacks (useStacks) and renders options from it,
always including the current value so it never silently blanks; StackBadge
gets a Supabase label.
A new backend stack now appears everywhere without a frontend edit.
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.
Follow the backend to the subdomain-only model:
- Service editor + create form: replace the Proxy path / Proxy host text fields
with a single "Expose" checkbox (writes proxy: { caddy: {} } or removes proxy).
- ServiceSummary/DeploymentSummary type: proxy_path/proxy_host → subdomain.
- ServiceCard / ServiceDetail: show the subdomain, linking to
<subdomain>.<domain> via a new subdomainUrl() helper (domain derived from the
dashboard's own host; null on a bare host / off mode).
Editing a service/job only persisted to castle.yaml; the unit isn't
regenerated and the process isn't restarted (the Restart button just runs
'systemctl restart' on the *existing* unit), so a change like a new port
appeared saved but never took effect.
The config panel now, after saving a service/job, shows an amber 'not live
yet' banner with an Apply button that runs POST /deploy {name} (regenerate
unit + Caddyfile) then, for services, POST /services/{name}/restart — so the
edit actually goes live. Programs are unaffected (no deploy/restart needed).
App builds clean.
- Add a 'hint' to the shared Field/TextField; annotate the config forms with
short, accurate descriptions of each field:
- program: source (working copy castle builds from), behavior (tool/daemon/
frontend), stack (optional toolchain template), repo/ref (for clone),
system deps (listed for reference, NOT auto-installed), commands.
- service: port (listened-on, health-checked, proxied; map via ${port}),
health path, proxy path vs proxy host, runs.
- job: schedule (cron → systemd timer), runs.
- ProgramFields: the Commands section is now editable (build/test/lint/
type-check/run), so a program with no stack can declare its own dev verbs
by hand — a declared command overrides the stack default. Verified the
commands/build shape round-trips through the config API.
App builds clean.
A service/job's env is now exactly its defaults.env — castle injects no hidden
convention vars. Values support ${port}/${data_dir}/${name} placeholders
(resolved at deploy, alongside ${secret:…}), so a program's own env var names
map to castle's computed values without hardcoding.
Why: the auto-injected <PREFIX>_PORT/<PREFIX>_DATA_DIR were a guess at the
program's env names — right for castle-scaffolded services, dead weight for
adopted ones (lakehouse carried two dead vars; notification-bridge/backup jobs
too). They also weren't visible in the config editor (computed at deploy), which
was the source of the 'four env vars but the UI shows none' mystery.
- core: resolve_env_vars gains a context (${port}/${data_dir}/${name});
deploy builds env from defaults.env only — no <PREFIX>_* injection, no
port_env. Removed the port_env field and the dead _env_prefix helper.
- cli: 'service/job create' gains repeatable --env KEY=VALUE (replaces
--port-env); 'program create' scaffolds <PREFIX>_PORT/_DATA_DIR: ${…} for new
daemons.
- app: removed the 'Port env' field; the Environment editor (defaults.env) is
the single place, with a placeholder hint.
- live migration: central-context/castle-api/power-graph/protonmail mapped their
real vars explicitly; lakehouse → just LAKEHOUSED_DAEMON_PORT: ${port}, data
stays in ~/.lakehoused. Verified all services healthy on their ports, dead
vars gone, zero failed units.
- docs: registry.md/design.md/stack guides + findings updated to the explicit
model.
core 94 / cli 24 / api 52 green; ruff + app build clean.
The Stage 2 editor split dropped the old confirm() — Remove program/service/job
deleted immediately on click. Restored confirmation on all three (FormFooter
window.confirm with a per-type message).
Removing a program that still has services/jobs referencing it would orphan
their program: ref. Now blocked:
- API: DELETE /config/programs/{name} → 409 'Programs with active jobs or
services cannot be removed. Delete these first: …' (authoritative).
- App: ProgramFields shows the blocked reason instead of a Remove button when
the program has deployments.
- CLI: castle delete refuses a program with referencing deployments not named
the same (which would survive the delete dangling).
Verified live: DELETE program lakehouse → 409. api 52 / cli 24 green; build clean.
CreateDeploymentForm builds a service or job in castle.yaml (PUT /config/...),
then deploys it (POST /deploy {name} → unit + Caddyfile + reload) and, for a
service, starts it (POST /services/{name}/start), then navigates to the new
detail page.
Reachable two ways:
- Program page Deployments section: 'Create service' / 'Create job' buttons,
prefilled from the program (name, program ref, run target, runner).
- Dashboard: standalone '+ Add service' / '+ Add job' (deployments can run
anything, not just castle programs).
Service form covers port / port_env / health / proxy path / proxy host; job
form covers schedule. Name validated against existing services/jobs.
Verified: the configs the form builds validate (PUT 200) and round-trip clean.
App builds; api 52 / core 94 green from prior stages.
- ProgramActions: install/uninstall (activate) shown only for tools and
no-service frontends. Daemons activate via a service/job, so the program
page no longer offers a misleading Install/Uninstall (which secretly
enabled/disabled the service).
- Program page: new Deployments section listing the services/jobs that run
the program, as links (a program → 0-N services/jobs).
- Service page: 'Runs' row from the run_target summary field (the old code
dug into manifest.run, which was empty pre-Stage-1), a Host row for
proxy_host, and a convenience link to the referenced program.
- lifecycle.activate on a daemon with no service now errors toward
'castle expose' instead of silently installing its binary to PATH.
core 94 green; ruff + app build clean.
The single service-shaped DeploymentFields was reused for all three sections,
so the program page bled service fields (port/proxy/health) and couldn't edit
program config, and the job page couldn't edit its schedule. Replaced it with:
- ProgramFields — description, source, stack, behavior, version, repo/ref,
system deps (+ read-only commands). Edits the program catalog entry.
- ServiceFields — run target, port, port_env, health, proxy path + host,
env/secrets. Prefills correctly now (Stage 1) and round-trips through PUT.
- JobFields — schedule, run target, env/secrets.
ConfigPanel selects the form by section. Shared Field/TextField/useEnvSecrets/
FormFooter helpers in detail/fields.tsx. Retired DeploymentFields. run editing
only touches python/command specs (container/node/remote run blocks preserved).
Verified: GET service manifest → PUT back validates 200. App type-checks/builds.
The dashboard widgets were named after the old 'component' concept. Renamed
each to what it actually renders:
- ComponentCard → ServiceCard (ServiceSummary, /services/, service actions)
- ComponentTable → ProgramTable (ProgramSummary[], the program catalog)
- ComponentEditor→ DeploymentEditor (DeploymentDetail, the unified type)
- ComponentFields→ DeploymentFields (AnyDetail)
- AddComponent → AddDeployment
Also purged the domain term 'component' from the rest of the app: the
useComponent hook → useDeployment, ConfigPanel + the three detail pages'
`component` prop/var → `deployment`, and the gateway/node table headers
(Component → Program / Deployment). Props renamed to match (component →
service / program / deployment). The React UI directory app/src/components/
keeps its conventional name.
App type-checks and builds clean.
- Updated the terminology from "components" to "programs" across the codebase, including in config loading, saving, and manifest specifications.
- Introduced a new `stacks.py` file to handle lifecycle actions for development stacks, implementing handlers for Python and React Vite stacks.
- Adjusted tests to reflect the new program structure and ensure proper functionality.
- Revised documentation to align with the new terminology and structure, ensuring clarity on the purpose and configuration of programs, services, and jobs.
