Follow-up to the harness fix: any unit whose ExecStart is a generated
wrapper (a NixOS `script =` block or a writeShellScript) gets its journal
SyslogIdentifier derived from the wrapper's store-path basename — an
opaque, unstable name. Pin an explicit stable identifier on every unit
hyperhive declares.
script/wrapper units (leaked store paths): forgejo-gpg-init,
hive-gateway-self-signed-cert, hive-tls-ca, hive-ci-prefetch,
hyperhive-isolated-dns, tea-login, forge-avatar-sync,
matrix-avatar-sync, hive-dashboard-links.
direct-binary units (basename already sane; explicit for tidiness +
future-proofing): hive-c0re, hive-priv, hive-matrix-daemon,
hive-bash-daemon, weston.
Only changes the displayed line identifier; journalctl -u <unit>
filtering (keys on _SYSTEMD_UNIT) is unaffected.
Short-lived leaf bounds the blast radius of a key compromise. Doc notes
the renewal caveat: re-sign is activation-only today, so a hive that
stays up >30 days without a rebuild would need a periodic re-sign timer
to avoid leaf expiry (follow-up).
A 10-year leaf is pointless given the leaf auto-rotates (re-signed
within 30 days of expiry) and is long enough to make browsers warn.
397 days sits just under the 398-day CA/Browser-Forum leaf cap (so
browsers accept it) while bounding the blast radius of a leaf-key
compromise. The re-sign runs at service activation (hive-tls-ca is a
oneshot, no timer), so 397 stays comfortably above any gateway
rebuild gap.
The dashboard vhost split static-vs-backend on the request Accept
header (map $http_accept $dashboard_spa_target), so the same URL
behaved differently by content-type — e.g. /api/state fetched with
Accept: text/html wrongly returned index.html.
Now that all hive-c0re routes live under /api/ plus the single
/webhook/knowledge endpoint, route by path instead: /api/ and
/webhook/ proxy to c0re (SSE settings on /api/), everything else
serves the dist with try_files $uri /index.html. Drops the
dashboard Accept-header map and the @c0re named location.
Updates docs/gateway.md accordingly.
`nixos-container update <agent>` (run by the hive-priv root helper) invokes
nix, which shells out by bare name to `git` whenever it has to fetch or
re-resolve a git-source flake input, and to `ssh` to dispatch builds to
remote builders. The hive-priv service `path` had neither, so an agent whose
config carries a git-source input — or a stale flake.lock whose node URL no
longer matches the flake's declared input, forcing nix to re-resolve at eval
— fails the build with `executing "git": No such file or directory`, and
remote-builder dispatch fails with `Could not find executable 'ssh'`.
Add `pkgs.gitMinimal` + `pkgs.openssh` to the path. Latent-bug fix: nix
legitimately needs both for any git-source input / remote build. Surfaced by
the bitburner agent's build failing on a git-source input re-resolution.
The internal forge is the canonical store for the meta flake, every
agent's config repo, and the internal/* repos, so it can no longer be
optional. Remove the services.hyperhive.forge.enable toggle:
- hive-forge.nix: drop the `enable` option; the forge config now
deploys gated on `services.hyperhive.enable` (it ships with hyperhive).
- hive-c0re.nix: HIVE_FORGE_URL env unconditional; forge-public-URL gate
drops the enable check (keeps behindGateway).
- hive-gateway.nix: local /etc/hosts forge entry keyed on behindGateway.
- hive-ci.nix: drop the now-moot `forge.ci.enable requires forge.enable`
assertion (forge is always present); reword the option doc.
- nix/docs/default.nix: drop the `forge.enable = mkForce false` stub
(option gone); the options-doc eval stays light via hyperhive.enable.
- hive-c0re forge.rs / hivectl.rs: reword 'forge.enable = true' error
text to 'wait for hive-c0re to start the container' (the runtime
token-absent path is unchanged — it's a bootstrap-timing check, not
the opt-out).
- docs/approvals.md, docs/ci.md: drop stale forge.enable references.
Migration: configs that set `services.hyperhive.forge.enable = false`
must drop the line — the forge is now mandatory.
Prereq/companion to #1838 (PR-based config flow, which assumes the forge
is always present).
Add swarm.peers.<domain>.caCert (path to a peer hive's root CA PEM),
trusted everywhere the hive's own internal CA is — so a self-signed
peer hive can federate (matrix) and any in-hive consumer validates its
certs.
Mechanism (reuses the existing hive-CA embedding): the meta-flake
renderer embeds a LIST of CA files next to each agent's flake —
hive-ca.pem (the hive's own self-signed CA, when active) plus each peer
caCert as peer-ca-<N>.pem — and emits them all in
security.pki.certificateFiles, so every agent trusts them at build
time. The matrix container trusts the same peer CAs for federation TLS.
Nothing is installed in the host trust store; the certs live in the nix
store (no mutable host file).
- meta.rs: embedded_ca_files() = hive CA + peer CAs (from new
HIVE_PEER_CA_PATHS env); ca_embed_state() tracks the list (content +
add/remove); sync_agents materialises + stages the list; render emits
the multi-entry certificateFiles. Tests cover hive-only / hive+peers
/ peers-only / none.
- hive-c0re.nix: HIVE_PEER_CA_PATHS service env (colon-joined caCerts);
caCert / certFingerprint option docs updated to the hive-wide scope.
- hive-matrix.nix + docs/swarm.md: scope + comment updates.
certFingerprint stays the c0re-only leaf-pin path.
nginx proxied `<hive>/` straight to hive-c0re:7000, and hive-c0re served the
dashboard dist itself via `tower_http::ServeDir` (from `HIVE_STATIC_DIR` baked
into its service env). So a frontend-only change rebuilt the hive-c0re unit and
restarted the core daemon — every operator session dropped its SSE stream for a
pure CSS/JS change.
The gateway nginx now static-serves the dashboard dist directly; hive-c0re's
dashboard router is API-only. The split uses the Accept-header SPA fallback (the
same `map $http_accept` pattern the matrix/agent vhosts already use), so no
backend prefix has to be enumerated: a browser navigation (Accept: text/html)
whose path is not an on-disk asset gets the SPA index.html; everything else
(every /api route, the bare action/mutation routes, the two SSE streams, the
knowledge webhook — all Accept != text/html) falls through `try_files` to the
`@c0re` named location and is reverse-proxied to hive-c0re. A new c0re route
needs no gateway change.
- hive-c0re.nix: expose the themed dist as a new internal read-only option
`services.hyperhive.c0re.servedFrontend`; drop `HIVE_STATIC_DIR` from the
service env (the router no longer serves files).
- hive-gateway.nix: read that option in host-module scope (dashboardDist),
static-serve `dashboard/` with the Accept-header `try_files ... @c0re` split;
`@c0re` carries `proxy_buffering off` + a 1d read timeout for the SSE streams
and a duplicated auth_basic block (named locations do not inherit it). The
dashboard map is unconditional; the matrix map stays gated on the matrix GUI.
- dashboard.rs: drop the ServeDir fallback + the HIVE_STATIC_DIR resolution; the
router 404s unmatched paths (the gateway only proxies non-static requests).
- hive-c0re/Cargo.toml: drop the now-unused tower-http dependency.
- docs/gateway.md: document the dashboard static split + the `@c0re` fall-through.
The store path is reachable inside the gateway nspawn container (shared
/nix/store), mirroring how HIVE_AGENT_FRONTEND_DIR already exposes the per-agent
UIs. The gateway and c0re changes must land together (atomic cutover) or the
dashboard 404s — this needs a watched gateway + c0re rebuild.
The CI container set `nix.settings.sandbox-fallback` but never
`nix.settings.fallback`, so a cache-miss build with an unreachable
remote build machine had no local fallback and hard-failed. A single
down or DNS-unresolvable `nix.buildMachines` host therefore turned every
fresh `nix flake check` red hive-wide, in ~30s, even for diffs that
can't affect the nix build (pure JS/markdown). Add
`nix.settings.fallback = true` so CI degrades to a slower local build
instead of failing.
Progressive enhancement: a brand-new agent's state root under
/var/lib/hyperhive/agents is created as a btrfs subvolume when the host
filesystem is btrfs, otherwise it falls back to a plain directory. No
existing agent is auto-migrated — the new path only fires when the root
does not yet exist, so plain-dir agents are left untouched until an
explicit opt-in upgrade.
Two new privileged ops (subvolume create/delete are root-only):
EnsureAgentSubvolume statfs-gates on btrfs, creates the subvolume, and
chowns it to the hive-core user so the normal state/claude/harness
mkdirs succeed inside it; DeleteAgentSubvolume btrfs-subvolume-deletes
the root iff it is actually a subvolume. hive-c0re calls Ensure before
the per-agent dirs are created (spawn/rebuild/InitConfig) and Delete on
the purge path only — destroy keeps the subvolume for revival, matching
plain-dir semantics. btrfs-progs added to the hive-priv unit PATH.
Per-subvolume usage accounting + optional quota is a separate
follow-up.
A bare `nix store ping` run as root with the daemon socket absent
resolves to a local store (root writes /nix/store directly) and pings
successfully, so the gate could false-pass at cold boot: nix-daemon.socket
carries ConditionPathIsReadWrite=/nix/var/nix/daemon-socket and is
condition-skipped until /nix/var goes read-write. systemd service units
don't source the profile that sets NIX_REMOTE=daemon, so auto-store
fallback to local is the real environment here.
Pin --store daemon so the readiness poll verifies the actual daemon
socket and the gate honours its wait-for-daemon contract instead of
passing against a local fallback while the daemon is still down.
Per review: the `tls.certDir == null && !tls.acme.enable` derivation was
duplicated in hive-gateway, hive-tls, and hive-ci. Expose it once as a
read-only internal option `services.hyperhive.gateway.useSelfSigned` (the
gateway module's single source of truth) and have hive-tls and hive-ci
consume it instead of re-deriving.
Eval-proven: gateway.useSelfSigned is true on the self-signed default /
false with tls.certDir, and the hive-tls (HIVE_TLS_CA_PATH) + hive-ci
(NODE_EXTRA_CA_CERTS) wiring derives correctly from it.
With self-signed TLS the gateway/forge serve a hive-CA-signed leaf and
forgejo's ROOT_URL is https://forge.<domain>. The CI runner's Node-based
actions (e.g. upload-artifact) POST to the ROOT_URL-derived artifact
endpoint and fail with "unable to verify the first certificate": Node uses
its own bundled CA bundle, not the system store, so it rejects the
self-signed chain. checkout etc. are fine — they hit the localhost http
registration URL.
Bind-mount the public hive CA cert (only ca.pem — never the hive-tls state
dir, which holds the CA + leaf private keys) into the hive-ci container and
set NODE_EXTRA_CA_CERTS on the runner service so every Node action trusts
it, hive-wide. Order container@hive-ci after the host hive-tls-ca service so
the cert exists before the bind-mount is set up. All gated on self-signed
mode; with an operator cert / ACME the public CA already validates and the
mount + env var are absent.
Eval-proven: self-signed → /run/hive-ca/ca.pem bind-mount (from
/var/lib/hive-tls/ca.pem), NODE_EXTRA_CA_CERTS=/run/hive-ca/ca.pem, and
container@hive-ci ordered after hive-tls-ca.service; certDir → all absent.
After a hive-ci restart the act_runner re-registers and immediately claims
any queued jobs, which can beat the in-container nix daemon coming up: its
nix-daemon.socket carries ConditionPathIsReadWrite=/nix/var/nix/daemon-socket
and is skipped until /nix/var is read-write, so the first nix-dependent
build dispatches into a cold daemon and hangs/retries (observed: a 55m48s
nix flake check vs the normal ~30s — a build-offload stall, not a code
failure; a non-nix step on the same runner passed in 1s, masking it).
Ordering the runner after/wants nix-daemon.socket does not help — a
condition-skipped unit satisfies systemd ordering immediately. Instead add
a blocking ExecStartPre that polls until the daemon actually answers
(nix store ping), placed with mkBefore so it runs ahead of the upstream
module's runner-registration ExecStartPre. The runner therefore cannot
register or claim jobs until nix is usable. Topology-agnostic (works
whether the daemon is in-container or a shared host socket); ~180s ceiling
then the unit fails cleanly rather than claiming jobs into a dead daemon.
Eval-proven: gitea-runner-hive's ExecStartPre is
[wait-nix-daemon, gitea-register-runner-hive] in that order.
Make self-signed TLS the gateway's default whenever no external TLS source
is configured, and deprecate the explicit selfSignedTls toggle. Self-signed
is now derived as `tls.certDir == null && !tls.acme.enable`, so an operator
selects a TLS mode by setting tls.certDir or tls.acme — or neither, for the
self-signed default. There is no http-only mode: matrix discovery hardcodes
https, so the gateway always terminates TLS.
The selfSignedTls option is kept as a deprecated no-op (warns when set to
false) so existing configs still eval. The two selfSignedTls mutual-
exclusion assertions and the HSTS-requires-TLS assertion are dropped — they
are impossible or vacuous now that self-signed is the floor. The hive-tls
module and the forge ROOT_URL scheme consume the derived value: the gateway
always terminates TLS, so behind the gateway the forge is always advertised
over https.
Updates docs/gateway.md (TLS-modes table, self-signed section, the removed
http-only section, firewall + discovery notes). Eval-proven: default →
self-signed (hive CA active, https ROOT_URL); tls.certDir → CA inactive;
selfSignedTls=false → deprecation warning fires.
Wire agents to trust the gateway's self-signed leaf at build time. When
the gateway runs self-signed TLS, hive-tls sets HIVE_TLS_CA_PATH in
hive-c0re's service env pointing at the host hive CA cert. The meta flake
renderer reads it and, when present, writes the public CA cert next to
flake.nix as hive-ca.pem and emits security.pki.certificateFiles so every
agent's system trust store includes the hive CA.
Build-time embedding (rather than a runtime bind-mount + bundle service)
keeps trust robust: the CA travels with the flake source, lands in the
standard NixOS trust store, and needs no per-process SSL_CERT_FILE
plumbing. Only the public CA certificate is embedded; the CA private key
never leaves the host. The cert is re-embedded and re-committed on CA
rotation even when the flake is otherwise byte-identical; when self-signed
TLS is off the embedded cert is dropped so the flake stays buildable.
Covers OpenSSL-based tools (git, curl) directly. A follow-up switches the
hive-forge reqwest client to native roots so it picks up the same store.
Replace the gateway's bare in-container self-signed leaf with a leaf
signed by a host-held hive CA. A bare self-signed leaf is its own trust
anchor, so every regeneration is a fresh anchor every consumer would have
to re-trust, and a runtime-generated in-container leaf cannot be wired
into an agent's build-time trust store at all. A stable CA fixes both: a
single anchor that agents and federation peers trust once, surviving leaf
rotation.
New hive-tls module: a host oneshot generates a long-lived CA (default
~20y) under services.hyperhive.tls.stateDir and signs a gateway leaf
(default ~10y, SAN covering the bare domain, forge., matrix. and the
wildcard). It is ordered before the gateway container so the leaf exists
when nginx starts. Active only when the gateway uses self-signed TLS
(default) and a domain is set; inert under operator-cert or ACME modes.
Gateway: bind-mount the host CA dir read-only at /run/hive-ca; the
existing in-container cert unit now imports the host leaf into nginx's
state dir (copy as root, key left root:nginx 0640 for the pre-start
config test) instead of generating one. Cert/key paths nginx serves are
unchanged.
Foundational step toward agent + federation trust of self-signed hives;
no behaviour change for agents yet (they still reach the forge over plain
http on port 80). Eval-proven across self-signed, certDir and the inert
default paths.
Fixes#1724. The forgejo ROOT_URL was hardcoded `http://` even when the
gateway terminates TLS, producing broken clone links and mixed-content
redirects for a TLS deployment.
Derive the scheme + port from gateway state: `https` (on httpsPort) when
the gateway terminates TLS (`gateway.selfSignedTls` or `gateway.tls.certDir`
set), `http` (on gateway.port) otherwise — dropping the port suffix on the
canonical port for the scheme (80 / 443). The per-agent in-cluster
HIVE_FORGE_URL is unaffected (it stays http on the gateway's :80 path);
this only changes the public ROOT_URL forgejo advertises.
Refreshes the `rootUrl` option description (the TLS scheme is auto-derived
now, so the manual-override-for-TLS note is gone).
Eval-proven: gateway.selfSignedTls = true → ROOT_URL =
https://forge.<domain>/; false → http://forge.<domain>/.
Per mara's review of #1718: the HIVE_FORGE_URL / HIVE_MATRIX_URL comments
carried "network isolation is now unconditional / shared-netns removed"
backstory that doesn't belong on those keys. Trimmed to describe just the
value (the gateway vhost) + the gatewayHost null-guard. The
isolation-removal narrative stays where it's on-topic — the network
module's own deprecated-option descriptions and warning text.
Per mara's review of #1718: this env block only exists when hyperhive is
enabled (it lives inside `config = mkIf cfg.enable`), so the
`if hyperhive.enable then gateway else loopback` branch was dead — the
loopback fallback could never be reached. Set HIVE_FORGE_URL to the
gateway vhost directly.
HIVE_MATRIX_URL drops the same redundant `hyperhive.enable` term but
keeps the gatewayHost null-guard — that one is a real fallback for a
domain-less config, not the dead enable branch.
Addresses argus's review of #1718: the HIVE_FORGE_URL / HIVE_MATRIX_URL
conditionals still keyed off the now-deprecated `network.enable`, so
setting it to `false` would point agents at host loopback (unreachable
from their private netns) even though isolation stays on — contradicting
the "deprecated and ignored" warning. Guard on the top-level
`hyperhive.enable` instead, so `network.enable` truly has no effect
anywhere and the loopback branch only covers a hyperhive-disabled host.
Eval-proven: with `network.enable = false`, HIVE_FORGE_URL now resolves
to the gateway vhost (`http://forge.<domain>`), and the deprecation
warning still fires.
Network isolation is validated working end to end (forge + matrix reach
the gateway under private netns), so the shared-host-netns mode is
removed — there is now one mode.
- hive-network.nix: the bridge/DNS block and the isolation overlay are
now unconditional whenever hyperhive is enabled (gated on
services.hyperhive.enable, not the per-feature toggles). The redundant
isolateContainers-implies-enable guard is dropped.
- network.enable and isolateContainers are kept as DEPRECATED no-op
options so existing configs that set them to true still evaluate
cleanly; setting either to false now warns (gated on hyperhive being
enabled, so a non-hyperhive host gets no spurious warning) and has no
effect. Both are slated for removal in a future release.
- hive-c0re.nix: the HIVE_FORGE_URL / HIVE_MATRIX_URL conditionals drop
the "&& isolateContainers" clause — agents always reach forge/matrix
through the gateway vhost now.
- hive-matrix.nix: refresh one stale comment.
The Rust lifecycle is env-driven (HIVE_NETWORK_ISOLATION), so no Rust
change is needed: the env is now always set, so the existing
private-netns path always runs.
Supersedes the default-on flip (the option it would have defaulted is
gone).
Forgejo's Actions artifact API hands the runner an upload URL built from
forgejo's ROOT_URL — the public forge domain (forge.<domain>), not the
runner's 127.0.0.1:<httpPort> registration URL. The hive-ci container shares
host netns but has no resolver entry for the hive's own domains (the
gateway's localHostsEntry only touches the host), so actions/upload-artifact
fails with 'getaddrinfo ENOTFOUND forge.<domain>' while normal CI (checkout
via the localhost registration URL) is unaffected. Add a networking.extraHosts
entry mapping the forge domain to loopback so the upload reaches the local
forge via the gateway.
Forgejo's local Actions-artifact storage defaults to
/var/lib/forgejo/data/actions_artifacts but Forgejo does not pre-create it.
The artifact endpoint ingests the chunked upload, then the merge-chunks step
fails with 'lstat .../actions_artifacts/tmpNNN: no such file or directory',
so every upload-artifact step dies after a successful build. Pre-create the
dir (forgejo-owned) via tmpfiles. actions.ENABLED already registers the
endpoints; this gives them somewhere to write.
Forgejo reported "does not have a signing key" on PRs despite the
forgejo-gpg-init service generating one. Two causes, both fixed:
- SIGNING_KEY = "default" resolves through the forgejo process's git
config (user.signingkey), not by scanning GNUPGHOME — and the keygen
never set it, so "default" found no key. forgejo-gpg-init now sets the
forgejo user's git user.signingkey to the generated key (+ commit and
tag gpgsign), with HOME pinned to the state dir so the global config
lands where forgejo reads it.
- The keygen guard was stamp-file based, so a partial state wipe that
lost the key while keeping the stamp would never regenerate. It's now
keyed on the actual secret key (regenerate iff gpg shows none) and
runs idempotently before forgejo on each start.
Also drops the heredoc for the gpg params in favour of printf (avoids
nix-string indentation fragility) and corrects the stale comment that
claimed "default" scans GNUPGHOME.
The runner hardcoded a 3h per-job timeout. Surface it as
services.hyperhive.forge.ci.jobTimeout so a stuck or runaway job is
bounded by a sane default while staying overridable for operators who
legitimately run longer jobs.
Default drops to 1h (comfortably covers a cold-cache nix build while
bounding a hang far sooner than the old 3h); raise it via the option
for genuinely long jobs. Accepts a Go duration string.
Resolves the stuck-runner concern from the CI-outage follow-up with a
runner-enforced job timeout rather than an external watchdog, per
operator direction.
Part of the tracker-tag cleanup: the hive convention is prose, not
issue-tracker tags, in code. Reword the 21 tags in the nix tree
(flake.nix + the hive-c0re/ci/gateway/network modules) to describe
the thing they pointed at, preserving the context without the tag.
Comment-only — no eval or logic change. Validated with nix fmt
(no reformatting) and nix flake check --no-build (all checks
evaluate clean); the full build check was skipped locally because
the shared remote builder is degraded, so CI will exercise the
build derivations once the runner recovers.
The gateway container starts alongside every hyperhive deployment, so
gating it behind a separate enable flag was a footgun: an operator who
set it false lost the only thing exposed to the outside while the
agent containers kept running. Re-gate the gateway config on the
top-level services.hyperhive.enable instead.
- hive-gateway.nix: drop the gateway.enable mkOption; gate the config
block on config.services.hyperhive.enable.
- hive-forge.nix: behindGateway now defaults to services.hyperhive.enable;
remove the behindGateway-requires-gateway assertion (now vacuous).
- hive-network.nix: remove both gateway.enable assertions (vacuous).
- hive-c0re.nix: drop the firewall.allowedTCPPortRanges 8100-8999
fallback that opened agent ports when the gateway was off (the
gateway is now the sole entry point); HIVE_GATEWAY_ENABLED is always
set since the gateway always runs.
- nix/docs/default.nix: remove the gateway.enable = mkForce false stub
(would be an eval error against the removed option; the gateway is
already re-gated on hyperhive.enable, which docs force false).
- hive-matrix.nix, dashboard.rs: comment/prose updates only.
BREAKING: operators relying on services.hyperhive.gateway.enable = false
to suppress the gateway must instead point their own reverse proxy at
the gateway's port. NixOS errors clearly on the now-unknown option.
Builds on the merged dashboard theming: the themed-frontend overlay now
swaps colors.css in both the dashboard/ and agent/ dist subtrees, and the
agent frontend dir (HIVE_AGENT_FRONTEND_DIR, which the gateway serves agent
static files from) points at the themed tree too. So when stylix is enabled
on the host, both the dashboard and the gateway-served agent UIs re-theme
from the host palette — still zero-op auto-detect, still a no-op (both dirs
on the unthemed dist) when stylix isn't imported.
Not covered: an agent reached directly on its own harness web server (no
gateway) serves from its per-agent mergedDist, built in the agent's own
nixosSystem with no host stylix access — that path needs the base16 palette
forwarded host->agent and is tracked separately.
When the operator's host config has stylix enabled, generate a base16
colors.css from its palette and overlay it onto the bundled frontend dist,
then serve that themed tree as the dashboard's HIVE_STATIC_DIR. Zero-op
auto-detect — no flake input, no operator action, no npm/esbuild rebuild
(a pure file-copy over the prebuilt dist). colors.css is the whole swap
contract; theme.css derives the semantic vars from the 16 base16 slots.
Guarded access (config.lib.stylix / config.stylix.enable via 'or' fallbacks)
makes it a clean no-op when stylix isn't imported — HIVE_STATIC_DIR stays
on the unthemed dist, which is what every non-stylix deployment + CI gets.
Dashboard surface only for now; the agent surface needs the base16 palette
forwarded host->agent (the per-agent harness builds its own dist) and is a
separate follow-up.
The systemd ExecStart carried every host-level setting as its own flag —
nine of them, including two escaped JSON blobs (the context-window map and
the model-price table). Collapse them into a single `--config <file>` JSON.
- Reuse the existing HiveEnv as the container-injected config shape (add
Deserialize + Default), and add a ServeConfig wrapper = flattened HiveEnv
plus the hive-c0re-local model_prices table (kept out of HiveEnv since it
is never injected into containers). serde(default) lets any field be
omitted and fall back to its canonical default.
- clap: add --config; the per-setting flags become optional overrides
(config file is the base, explicit flags win — preserves hivectl/debug
ergonomics and bare `hive-c0re serve`).
- Coordinator::open and cmd_serve now take the bundled HiveEnv, which drops
their too_many_arguments clippy allows. cmd_serve keeps a single
too_many_lines allow (inherent daemon-boot orchestration, not arg-driven).
- nix: write the config as JSON to the store + pass --config, so ExecStart
is one short line.
- Add a round-trip test proving the flatten + per-field defaults work.
Closes the ExecStart-length issue.
Two small follow-ups after the modelPrices PR (#1442):
- nix/modules/hive-c0re.nix: the `modelPrices` option `example` still
showed the old 5-minute sonnet `cache_write = 3.75`; the default is now
the 1-hour TTL `6.0`. Bump the example to match so it doesn't mislead.
- frontend/packages/agent/agent.css: remove the dead `.stats-empty-note`
selector (no element uses it — the stats empty state paints on canvas).
