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.
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.

Cross-checked every doc against the code and fixed the stragglers the
apply/gateway/subdomain refactors left behind:
- Retired `tls: internal` mode: dropped the misleading reference in
registry.md and the stale comment in config.py GatewayConfig (only
off|acme exist; the dns-and-tls.md "was removed" note is kept as
accurate history).
- Subdomain-only routing: fixed "path-based routing" claims in design.md
(proxy list + mesh), "path prefix or host" → host, and the "path-prefix
routes stay on :port" line in registry.md.
- Frontends serve at their subdomain root (VITE_BASE=/), not /<name>/:
fixed supabase.md (x2), the scaffold.py docstring, the stacks.py build
comment, and design.md's "serve prefix baked in" line.
README, AGENTS, developing-castle, dns-and-tls audited clean. Verified
against code; core 129 / cli 31 pass; ruff clean.
Rework the supabase stack so every app owns an isolated Postgres schema
(= program name) instead of sharing `public` with a table_prefix. This
gives a clean, knowable teardown and drops migration version tracking to
per-app, so version tokens can no longer collide across apps.
- stacks: add StackHandler.owns_data + teardown() (default no-op). Supabase
build now creates+grants the app schema, tracks migrations in
<schema>.schema_migrations, and applies each with search_path set to the
schema (write unqualified names). teardown = drop schema <app> cascade.
Fix _substrate_db_url default port 5432 -> 5433 (substrate's direct PG).
- deploy: derive ${supabase_app_schemas} from registered apps; substrate maps
PGRST_DB_SCHEMAS: public,storage,graphql_public${supabase_app_schemas} so
PostgREST exposes each app schema (restart substrate after add/remove).
- delete: generic owns_data -> teardown path behind new --purge-data flag,
replacing the hardcoded supabase remnant note.
- scaffold + docs: new apps born schema-isolated (unqualified tables,
db:{schema}, schema: in supabase.app.yaml).
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.
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).
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
migration runner (plan_migrations + psql build) and deno dev-verbs.
- docs: docs/stacks/supabase.md, registered in CLAUDE.md; compose runner
documented in registry.md.
- tests: compose run/stop cmd, systemd ExecStop, compose host-route TLS,
migration planner, supabase verb resolution, create --stack supabase.
pnpm 10+ runs a deps-status check before `pnpm <script>` that wants to
purge and reinstall node_modules, aborting in a non-TTY build with
ERR_PNPM_ABORTED_REMOVE_MODULES_DIR_NO_TTY. It is a false positive for a
build verb (which builds, not installs), so ReactViteHandler now prepends
--config.verify-deps-before-run=false to every pnpm call, building against
the existing modules. CI=true is kept as a general non-interactive guard.
Generated systemd units hardcoded a thin PATH (~/.local/bin + system dirs)
while dev-verb builds used a separate _EXTRA_PATH_DIRS list, so a service
could be built and run with different tools on PATH. Hoist a single
USER_TOOL_PATH_DIRS in config.py, consumed by both stacks._build_env
(build) and the systemd unit generator (runtime).
Also prefer pnpm's modern $PNPM_HOME/bin shim over the bare $PNPM_HOME dir
(older installs leave a stale version wrapper there) and add
/usr/local/go/bin so Go-based builds/services resolve their toolchain.
The check composite returned ActionResult with no output on success, so the
dashboard's 'Check All' (and the CLI) showed nothing when checks passed — only
a failing sub-verb ever produced output. It now accumulates each sub-verb's
output with a ✓/✗ marker (lint / type-check / test), on both success and
failure, so the output panel always shows what ran.
Also fixes lan-info's type-check: socket.getaddrinfo sockaddr is loosely typed,
so str(infos[0][4][0]) makes the address an unambiguous str.
core 94 green; ruff clean; verified POST /programs/lan-info/check returns output.
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.
#1 Positional dest unified to `name` across info + dev verbs (was `project`).
#2 install/uninstall help now states the activate semantics (tool→PATH,
service/job→systemd, frontend→served) rather than 'to PATH'.
#4 `service status` (a plural op) moved to `services status`; the singular
`service` group is enable/disable only.
#5 `list --behavior` now filters the program *catalog* by its real behavior
field. behavior (what a program is) and service/job (how it's deployed) are
separate axes: `list` shows a Programs catalog plus Services/Jobs deployment
views; a behavior filter scopes the catalog only.
#6 `list` uses lifecycle.is_active uniformly for the status dot (tool on PATH /
service running / job timer / static frontend served) instead of registry
presence.
#7 New `castle restart <name>` — restart a service (unit) or job (timer).
#8 New `castle status` — unified services + jobs + programs activation view.
#9 New `castle format [name]` dev verb (ruff format / pnpm format); wired into
stacks DEV_ACTIONS + handlers.
#10 New `castle up` — deploy + start everything in one shot.
Docs: CLAUDE.md command reference refreshed. Tests updated to the two-axis
list model (+ a daemon-behavior program fixture). core 92 · cli 24 · api 52
green; ruff clean.
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.
Move all instance state into ~/.castle/ with clear separation:
- code/ — user project source (was components/)
- artifacts/ — generated specs, built content (was generated/, static/)
- data/ — service runtime data (was /data/castle/)
- secrets/ — credentials
castle.yaml moves to ~/.castle/castle.yaml as the canonical location.
Source paths use repo: prefix for git repo programs (castle-api, app)
and relative paths for user projects (code/central-context).
Add idempotent install.sh for bootstrapping infrastructure (Docker,
Caddy, MQTT, Postgres, Neo4j) with interactive service detection.
Remove components/ from repo (now in ~/.castle/code/), deinit
submodules, remove .gitmodules.
- 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.
