2b4e928afe feat(#1867): make the internal forge mandatory (remove forge.enable)
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).

4db8a8cd3d feat(#1843): static-serve the dashboard via the gateway, hive-c0re API-only
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.

3b8e77c1c1 nix(gateway): factor the self-signed condition into a shared option
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.

1a3f82a459 nix(gateway): self-signed TLS as the implicit default, deprecate the toggle
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.

74a90fd7d6 nix(tls): host hive-CA + gateway leaf for self-signed mode
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.

eb61660d35 chore(nix): replace tracker tags with prose in nix comments
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.

fdf05c1673 refactor(gateway): make the gateway unconditional — remove gateway.enable
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.

36e5e19d8e refactor(gateway): extract the _ vhost agent + dashboard location groups

of named groups — matrixRedirectLocations // wellKnownLocations //
agentLocations // dashboardProxyLocation // <auth optionalAttrs> — instead

lib.optionalAttrs already).

d7e4028a16 refactor(gateway): extract the _ vhost matrix location groups into named bindings
Step 2 of the hive-gateway.nix vhost cleanup (follows the sub-domain
vhost extraction). Lift the two deepest-nested location groups of the
default _ server — the /matrix/ 301 redirect and the
.well-known/matrix/{client,server} discovery JSON, each carrying its own
let block — out of the inline //-chain into matrixRedirectLocations /
wellKnownLocations bindings. The _ vhost locations now open with
matrixRedirectLocations // wellKnownLocations // ... instead of two ~60-line
nested literals. agent/dashboard/auth groups stay inline (a later step).

a03aafb004 refactor(gateway): extract forge + matrix sub-domain vhosts into named bindings
Step 1 of the hive-gateway.nix vhost-builder cleanup. The two
sub-domain vhosts (forge, matrix) were inline `lib.optionalAttrs`
blocks `//`-appended to the virtualHosts attrset, burying the
top-level structure. Lift them into `forgeVhost` / `matrixVhost`
bindings in the config-closure let so the composition reads as
`{ "_" = ...; } // forgeVhost // matrixVhost` — the three vhosts are
now visible at a glance. Also fixes a garbled merge-mangled comment on
the nginx-reload host-trigger.

Pure readability refactor, eval-identical: verified the generated
`services.nginx.virtualHosts` toJSON is byte-identical before/after
(8888 bytes, diff empty) on a host with matrix+forge+gui+auth+tls all
enabled. The deeper `_` vhost location-group extraction is a follow-up.

48b7c24265 fix(nix): emit explicit port in .well-known/matrix/server delegation
The matrix server-server spec resolves a portless m.server delegated
host to the federation default port 8448 (not 443 — the URL convention
that https implies 443 does not apply to the m.server field). The
gateway reused publicPortSuffix, which intentionally drops :443 for the
client base_url, so .well-known/matrix/server advertised the bare
gateway host. Peers then federated to <gatewayHost>:8448, which nothing
listens on, while the federation endpoint actually lives on the gateway
443 vhost (/_matrix/ proxied to tuwunel). Always emit the explicit port
in the federation delegation so peers reach the live 443 endpoint.

fb93cbf5c2 feat: add tls.acme mode — nginx inside container manages Let's Encrypt
per mara's suggestion: instead of bind-mounting operator certs, let
nginx handle ACME directly inside the gateway container.

- tls.acme.enable: lets nginx obtain + renew via HTTP-01 challenge
- tls.acme.email: ACME account contact (required when enable=true)
- security.acme in container config when acme.enable
- hasTls includes acme.enable → https, httpsPort listen, firewall
- mutual exclusion assertions: acme vs selfSignedTls vs certDir
- docs/gateway.md: four-mode TLS table + ACME section

typical setup:
  selfSignedTls = false; openFirewall = true;
  tls.acme = { enable = true; email = "admin@example.com"; };

44122c66de feat(#594): gateway operator-cert TLS mode (tls.certDir)
add services.hyperhive.gateway.tls.certDir option: operators with a
CA-signed cert (Let's Encrypt, corporate CA) point at the ACME output
dir instead of using the auto-generated self-signed cert.

- tls.certDir: host path bind-mounted r/o at /run/hive-tls/ in gateway
- tls.certName / tls.keyName: filenames within certDir (default: cert.pem / key.pem, matches nixpkgs security.acme layout)
- hasTls = selfSignedTls || certDir != null: publicScheme=https in both cases
- assertion: selfSignedTls=true + certDir set together is an error
- openFirewall: httpsPort opened in both TLS modes
- docs/gateway.md: TLS modes table + operator-cert section
- docs updated in swarm.md peer config reference in the cert TLS section

when using operator cert, swarm peers can omit certFingerprint —
standard CA bundle handles trust automatically.

167b4fa1f3 refactor(gateway): fixed htpasswd path, drop htpasswdFile option
Remove the custom htpasswdFile option and bind-mount. The htpasswd file
now lives at the fixed path /var/lib/hyperhive/gateway/gateway.htpasswd
on the host, which is already exposed inside the container at
/run/hive-state/gateway.htpasswd via the existing gateway state
bind-mount — no extra bind-mount needed.

A tmpfiles rule pre-creates the file so nginx can open it even before
any users exist (empty file → all requests return 401, which is correct).

hivectl gateway commands default --file to the standard path so
`hivectl gateway create-user alice` just works without any flags.

a248c6bee1 feat(gateway): custom 401 page explaining how to add users
When HTTP Basic auth is enabled and credentials are absent or rejected,
nginx serves a Catppuccin-styled 401 page that tells the operator which
hivectl command to run to create a user. Uses error_page 401 =401 so
the browser still receives a 401 status (login dialog fires on first
visit) while getting a human-readable body when the dialog is dismissed.

The exact-match location (= /__hive_auth_unauthorized) beats location /
in nginx's prefix ordering so the internal subrequest does not loop back
through auth_basic.

Add `hivectl gateway {create-user,delete-user,list-users}` subcommands for

Also fix the NixOS module assertion: `cfg.auth ? htpasswdFile` is always
true in the module system (declared options always exist as keys); switch
to `nullOr path; default = null` + `!= null` check so the assertion
actually fires with a useful error when enable=true but no file is set.
Guard bind-mount and nginx config against null to prevent eval errors.

25d2951d1e feat(gateway): htpasswd Basic auth — close #1010
Replaces the earlier PAM+binary approach with nginx's built-in
`auth_basic` module. No new binary, no new systemd service, no PAM.

New option `services.hyperhive.gateway.auth`:
- `enable` — off by default
- `htpasswdFile` — host path to an htpasswd file (required when enable)
- `realm` — WWW-Authenticate realm string (default "hyperhive");
  restricted to `strMatching "[^\"$]*"` to prevent nginx config injection

When enabled:
- the parent directory of `htpasswdFile` is bind-mounted read-only
  into the gateway container at `/run/gateway-auth/`
- the `"/"` proxy location gets `auth_basic` + `auth_basic_user_file`

Create credentials: `htpasswd -Bc /path/to/file alice` (BCrypt).

d4409b27a3 feat(gateway): PAM auth against host — close #1010
Adds opt-in HTTP Basic auth to the hive-gateway backed by the host PAM
stack + group membership check.

New binary `hive-gateway-auth` (hive-c0re workspace):
- Axum HTTP service on 127.0.0.1:7002 (host loopback)
- Decodes Basic credentials, authenticates via pam_unix.so
- Checks membership in `hyperhive-operator` group (or custom)
- Returns 200 / 401 / 403; nginx `auth_request` consumes these

New options under `services.hyperhive.gateway.auth`:
- `enable`      — off by default
- `port`        — auth service port (default 7002)
- `realm`       — WWW-Authenticate realm string (default "hyperhive")
- `group`       — required host group (default "hyperhive-operator")
- `pamService`  — PAM service name (default "hive-gateway")

Host-side NixOS wiring:
- `users.groups.hyperhive-operator` declared when default group used
- `/etc/pam.d/hive-gateway` emitted via `security.pam.services`
- `systemd.services.hive-gateway-auth` runs the auth binary as root
  (needs /etc/shadow access for pam_unix.so)

Gateway container nginx wiring:
- `location = /__hive_gateway_auth` — internal proxy to auth service
- `auth_request /__hive_gateway_auth` on the `"/"` proxy location
- `@hive_auth_required` named location adds WWW-Authenticate: Basic
  header on 401 so browsers display a login prompt

Workspace deps: pam = "0.8"; flake.nix: linux-pam added to
nativeBuildInputs so pkg-config can find libpam at build time.

01d7c37af2 gateway: fix nginx reload — trigger from host via systemd-run (#889)
The #872 path-unit approach was silently broken: IN_MOVED_TO from an
atomic rename on the host does not propagate across the nspawn
mount-namespace boundary into the container, so the watcher inside
the gateway container never fired.

Fix: after each agents.conf write, c0re calls
`systemd-run --machine=hive-gateway -- nginx -s reload` from the host.
The reload is best-effort (logged on failure, not fatal).

Remove the now-unused `hive-gateway-agents-conf.path` +
`hive-gateway-nginx-reload.service` from the gateway container config.

b50f182396 hive-gateway: note common-case dnsmasq address redundancy (argus 🟡 on #845)
forge/matrix subdomain address rules are redundant when those are
sub-domains of hyperhive.domain (dnsmasq's /<domain>/ matches
sub-domains). Keep explicit for the cross-domain case (e.g.
forge.domain = "git.example.com") + add a comment explaining
the trade-off.

ed3b9d853e nix/hive-network: bridge + dnsmasq resolver, opt-in (#805 v1)
Stand up the host-side bridge interface + per-agent DNS resolver
ahead of #14 (netns isolation). Mara on #805#11541: "we need it
before #14 so nothing breaks when we switch over". v1 ships the
endpoint live but containers stay on shared host netns — when #14
flips them to private netns the DNS contract is already there.

Shape:

- new `nix/modules/hive-network.nix` with `services.hyperhive.network.*`
  options (enable + bridgeName + bridgeIp + bridgePrefixLength +
  upstreamDns). Default off. Imported from `hive-c0re.nix`.
- bridge interface via `networking.bridges` (no slave NICs at v1;
  per-agent veth pairs attach once #14 lands).
- bridge IP assigned via `networking.interfaces`.
- `networking.firewall.interfaces.<bridge>.allowed{UDP,TCP}Ports =
  [ 53 ]` opens the resolver on the bridge interface only —
  other interfaces stay closed.
- dnsmasq config added to the existing `hive-gateway` container
  (mara on #805:10957: "put the resolver into the gateway container").
  Listens only on `bridgeName` + `lo`; authoritative for
  `<hive-domain>`, `forge.<hive>`, `matrix.<hive>` answering with
  the bridge IP; forwards everything else to upstream.
  `resolveLocalQueries = false` keeps the gateway container's own
  resolver untouched.

Asserts `services.hyperhive.domain != null` + `gateway.enable =
true` — both required for the resolver to be meaningful.

Docs: new `docs/network.md` covering v1 vs v2 split, container shape
rationale, default addressing, resolver behaviour, firewall posture.

`nix flake check` clean.

e1bc9e42f1 hive-gateway: tmpfiles rule for /run/hive-agent (argus 🟡 on #829)
Defensive against the fresh-boot-before-any-agent-spawn window where
the bind-mount source wouldn't exist from c0re's per-agent
`set_nspawn_flags` mkdir chain yet. nspawn auto-creates missing
sources, so this is intent-explicit rather than functional fix.

3a29aee001 nix/hive-gateway: UDS upstream for /agent/<name>/ (#784 phase 2 step 3)
Switch per-agent gateway upstreams from TCP loopback to unix-domain
socket when the agent has opted in via `hyperhive.web.useUnixSocket`
(#822). Coexists with the TCP path during rollout.

Changes:

- New `agentSocketsFile` option (default
  `/var/lib/hyperhive/agent-sockets.json`) — c0re writes the map
  there via `hive_c0re::agent_sockets::write` (#809).
- `agentSocketsTable = lib.importJSON ...` (graceful empty when
  file missing).
- `agentUpstreamFor name port` picks `http://unix:<path>:/` when the
  socket has a JSON entry AND the file exists at eval time; else
  `http://127.0.0.1:<port>/`. Path-exists gate guards against
  c0re's blanket-emit shape during the canary window (agents in
  `agent-sockets.json` who haven't actually flipped have no
  bound socket on disk → fall back to TCP). Damocles will ship a
  `.bound` marker filter on the c0re side (#784 step 2d
  follow-up); once that's in, the path-exists check is redundant
  but harmless. Step 4 drops it entirely along with the TCP
  fallback.
- `containers.hive-gateway.bindMounts."/run/hive-agent"` —
  read-only, unconditional. Inert when no agents have opted in.
  Required so nginx inside the gateway container can `connect(2)`
  to the per-agent sockets damocles's #813 bind-mounts into agent
  containers at the same paths.

Docs:

- `docs/gateway.md::Per-agent UDS upstream (#784)` — full rollout
  flow, subdir-bind rationale (damocles #813), eval-time gate
  explainer, step 4 drop plan.

`nix flake check` clean; `nix fmt` clean.

Canary plan: once #822 (`useUnixSocket` option) lands + this PR
merges, manager flips atlas's agent.nix to `useUnixSocket = true`
via the config-update flow. End-to-end validation against atlas
before broader rollout.

24775845a3 nix/hive-gateway: static not-found + unreachable pages for /agent/<name>/ (#755)
mara on #755: "e.g. /agent/name should show an error page stating
that the agent could not be found if missing in json or that it is
not reachable if we get a connection error. we dont want a fully
generic fallback, only for routes already special cased in the
nginx config."

Adds two static HTML pages built at deploy time via
`pkgs.runCommand "hyperhive-agent-error-pages"`:

- **not-found.html** — served when `/agent/<unknown>/...` hits the
  bare `/agent/` catch-all. The catch-all `return 404`s, and
  `error_page 404 = /__hive_agent_not_found` rewrites to the static
  page.
- **unreachable.html** — served when `/agent/<known>/...` proxy_pass
  to the harness returns 502 / 503 / 504. `proxy_intercept_errors
  on` + `error_page 502 503 504 = /__hive_agent_unreachable` on each
  per-agent location block rewrites to the static page.

Mechanics:

- `agentErrorPagesDir` (in the `let` block) is a `runCommand` that
  emits two HTML files using a `<<EOF` heredoc — no template engine
  needed.
- Two `internal` nginx locations (`= /__hive_agent_not_found`,
  `= /__hive_agent_unreachable`) `alias` the exact files. `internal`
  keeps the URIs unreachable from direct operator request — only
  nginx's own error-handling can hit them.
- Per-agent location blocks pick up the `error_page` directive
  through the existing `lib.mapAttrs'` over `agentPortsTable`. No
  per-agent generated content; same static page for all.
- `/agent/` catch-all generates from a tiny optionalAttrs alongside
  the per-agent block — both are no-op when the agent table is
  empty (matches the pre-#15 shape).

Pages: minimal inline CSS, catppuccin palette matching the
dashboard (`#1e1e2e` bg, `#cdd6f4` text, `#cba6f7` not-found heading,
`#f9e2af` unreachable heading). No frontend-dist dependency — render
even when hive-c0re is down. Both link back to `/`.

Per mara's "only for routes already special cased" — scope stays
narrow. Forge / matrix / fluffychat keep nginx defaults; extending
the custom-error pattern to other vhosts is a separate follow-up
if/when needed.

Verified:
- nginx location attrset has `["/", "/agent/", "= /__hive_agent_not_found", "= /__hive_agent_unreachable"]`
- container toplevel builds clean (`nixos-system-hive-gateway-26.05pre-git`)
- `docs/gateway.md::Per-agent error pages` section captures the
  design + rationale + intentional narrowness

Closes #755.

922057e81b docs/gateway.md: extract big-picture gateway docs, trim in-code comments (mara #775:9988)
mara on PR #775: "this is too much docs in code - move bigger picture
stuff to md files and put refs in code"

New `docs/gateway.md` consolidates the gateway architecture story
that was spreading across long inline comments in `hive-gateway.nix`,
`hive-matrix.nix`, and `hive-forge.nix`:

- vhost map (which URL serves what, which upstream, which option)
- matrix discovery flow (.well-known → sub-domain delegation
  sequence)
- Accept-header SPA fallback pattern (#686 / #729 design history)
- local-dev `localHostsEntry` story
- sub-domain rationale (mara verdict tracking) + when sub-path is
  right (hyperhive-internal apps)
- per-vhost tuning knobs (forge LFS, matrix long-poll, agent SSE)
- sequencing history (which PR added which routing piece)

In-code comments in the two nix modules get trimmed to short refs
into the doc — keeps the *why* in the markdown while the *what*
stays alongside the code:

- hive-gateway.nix: top-of-file comment, `agentPortsTable`,
  `appendHttpConfig`, every location block + vhost
- hive-matrix.nix: `fluffychat-web-fixed`, `fluffychat-web-imaging`,
  the dart compile postInstall

README.md gets a new row in the docs table pointing at gateway.md.

Verified `nix eval` still resolves the same vhost + location layout
after the comment trim — no behavioral change, just less in-code
prose.

df549ed2a5 nix/hive-{matrix,gateway}: host fluffychat at matrix.<hive>/, 301 from <hive>/matrix/ (#772)
mara on #764:9897: "host the fluffy chat app at / as follow up?"

Moves fluffychat-web from the bare-domain sub-path
(`<hive>/matrix/`) to the matrix sub-domain root
(`matrix.<hive>/`). Follow-up to #764 (matrix vhost itself), per
mara's gateway-architecture verdict (sub-domain for external standard
apps, sub-path for hyperhive-internal). Stacked on
`atlas/747-matrix-behind-gateway` — depends on #764 landing first.

## Mechanics

**hive-matrix.nix:**
- Drop `flutterBuildFlags = [ "--base-href" "/matrix/" ]` from
  `fluffychat-web-fixed`. Upstream default `--base-href "/"` is correct
  at sub-domain root.
- Update option docs to reflect new mount point.

**hive-gateway.nix:**
- `$matrix_spa_target` map target flips from `/matrix/index.html` →
  `/index.html` (sub-domain root now).
- New `<hive>/matrix/*` location: `rewrite ^/matrix/(.*)$
  matrix.<hive>/$1 permanent;` — 301 redirect preserves bookmark +
  deep-link compatibility for `<hive>/matrix/#/rooms/...` URLs during
  the transition.
- `<hive>/matrix/config.json` location removed (moved to `/config.json`
  on the matrix vhost).
- Matrix vhost (#764) gains `/` location: serves fluffychat dist as
  static files with the Accept-header SPA fallback (`/_matrix/`
  proxying to tuwunel keeps working via nginx longer-prefix-wins
  precedence). When `gui.enable = false`, `/` returns 404 cleanly.
- Matrix vhost gains `= /config.json` for the FluffyChat boot-config
  pre-fill (#736).

## Verified

```
vhosts:        ["_", "forge.test.local", "matrix.test.local"]
bare locations: ["/", "/matrix/", "= /.well-known/matrix/client",
                 "= /.well-known/matrix/server"]
matrix vhost locations: ["/", "/_matrix/", "= /config.json"]
/matrix/ extraConfig: "rewrite ^/matrix/(.*)$ http://matrix.test.local/$1 permanent;"
matrix vhost / alias: /nix/store/...fluffychat-web-2.6.0/
```

Full container toplevel builds clean.

## Risk

Medium. Two breaking changes for operators:

1. **Bookmark migration**: `http://<hive>/matrix/#/rooms/...` 301s
   to `http://matrix.<hive>/#/rooms/...`. Browser bookmarks +
   shared links keep working via the redirect; can be cleaned up
   once it's been in the wild long enough.

2. **fluffychat-web dist hash changes**: dropping the
   `--base-href "/matrix/"` flag changes the derivation hash, so
   `gui.package` rebuilds even though the source is the same.
   Operators on substitute caches will fetch the new dist; building
   from source takes the same time as before.

The `.well-known/matrix/{client,server}` delegation (already
advertising `matrix.<hive>` per #764) means matrix clients
auto-discover the new location — no client config change needed.

## Sequencing

**Depends on #764** — needs the matrix vhost to host the new `/`
location. Merge after #764 lands + soaks. If #764 changes shape
during review I'll rebase + force-push.

Closes #772.

01cc664d76 nix/hive-{gateway,matrix}: matrix vhost at matrix.<hive-domain> + .well-known delegation (#747)
mara on #747:9722: "this still seems to be an issue in current version"
(after #751 closed without merge). Mirroring the forge sub-domain
pattern just merged as #754 for matrix per mara's #749:9609 verdict
(sub-domain over sub-path for forge + matrix, "not user-visible for
matrix because the .well-known/matrix/{client,server} redirect routes
clients through automatically").

## Mechanics

**New `services.hyperhive.matrix.gatewayHost`** — nullable str, defaults
to `matrix.<services.hyperhive.domain>` when hive-domain set, else
null. Full hostname (`matrix.darkest.space`, `homeserver.internal.lan`)
for bespoke shapes per mara's #754:9684 "specify full domain in
options instead" pattern.

**Gateway:** new `server { server_name = matrixCfg.gatewayHost; }`
block proxying `/_matrix/...` → `http://127.0.0.1:<httpPort>/_matrix/...`
with matrix-spec CORS + tuned for long-poll `/sync` (1h timeout) +
typical media uploads (50M body cap). `/` returns 404 — nothing
else lives at the matrix vhost. Matches the forge vhost shape from #754.

**`.well-known/matrix/{client,server}`** (already served at bare hive-
domain since #660): now points at `matrixCfg.gatewayHost` (no port
suffix when gateway is on the canonical port 80) instead of the
direct `<hive-domain>:<httpPort>` shape. Falls back to direct shape
when `gatewayHost = null` (no hive-domain, or operator nulled it).

**`localHostsEntry` extension**: `/etc/hosts` (when set) now adds the
matrix sub-domain → 127.0.0.1 alongside hive-domain + forge.domain.
`lib.unique` collapses any duplicate (edge case if operator sets
gatewayHost equal to hive-domain).

## Verified via `nix eval`

```
vhosts:         ["_", "forge.test.local", "matrix.test.local"]
gatewayHost:    "matrix.test.local"
client wellknown: m.homeserver.base_url = "http://matrix.test.local"
server wellknown: m.server = "matrix.test.local"
/etc/hosts:     ["test.local", "forge.test.local", "matrix.test.local"]
```

## What this fixes for #747

mara's HAR showed `GET /.well-known/matrix/client` and
`GET /_matrix/client/versions` both failing on `pr1ma.darkest.space`:

1. **`.well-known/matrix/client`** was advertising
   `http://pr1ma.darkest.space:8008` — that URL only works if tuwunel's
   port 8008 is firewall-open to the operator's browser (it isn't by
   default — `services.hyperhive.matrix.openFirewall` defaults to false
   since #651). Now advertises `http://matrix.pr1ma.darkest.space/`
   which goes through the gateway on the (already-open) port 80.

2. **`/_matrix/client/versions`** was hitting the bare-domain `"_"`
   vhost, which has no `/_matrix/` location — fell through to `/` →
   c0re's dashboard upstream → 404. Now hits the new `matrix.<hive>`
   vhost which proxies the request to tuwunel cleanly.

server_name + serverName unaffected — matrix identifiers (`@alice:<hive>`)
still embed the bare hive-domain per #660; only the wire-level transport
URL moves to the sub-domain.

## Risk

Medium. Existing matrix tokens / sessions stay valid because:
- `serverName` (the identifier domain) doesn't change
- tuwunel's `/_matrix/` endpoints serve the same requests, just reached
  via the new sub-domain instead of the direct port

Operators with `services.hyperhive.matrix.openFirewall = true` and
external clients reaching `:8008` directly keep working too — the
sub-domain vhost is additive, doesn't take away the direct port.

## Sequencing

This is a parallel matrix-side mirror of #754 (forge). Both follow
the same mara-verdict pattern; once both have soaked, the gateway-
behind-everything story is done for v0.

Closes #747.

9c27c4076f nix/hive-forge: unify on cfg.domain as full hostname, drop subdomain label (mara #754:9684)
mara on PR #754: "would it be better to specify full forge domain in
options instead?"

Drops the awkward `cfg.subdomain` label option. Now `cfg.domain` is
the single source of truth for both the forgejo `DOMAIN` setting
(existing semantics) AND the gateway vhost server-name (new).

## Before / after

```nix
# before: separate label + cfg.domain juggling
services.hyperhive.forge.subdomain = "forge";       # → forge.<hive>
services.hyperhive.forge.domain = "localhost";      # unused for vhost

# after: full domain, single option
services.hyperhive.forge.domain = "forge.darkest.space";  # ← used for ROOT_URL + vhost
```

## Default

`cfg.domain` default auto-derives:
- `forge.<services.hyperhive.domain>` when hive-domain is set
- `"localhost"` otherwise (pre-#749 direct-on-port shape)

So the common case (hive-domain set) gets `forge.<hive>` for free,
operators with a bespoke shape (`git.example.com`) set the full
hostname directly.

## Assertions

- `cfg.domain != ""` — empty would render `.<hive>` shaped garbage
  in both server_name + /etc/hosts.
- `cfg.behindGateway → gateway.enable` — can't route through a
  gateway that isn't running.

(The previous "subdomain = empty" assertion is dropped — that
edge case is gone with the rename.)

## Verified

- default with `hyperhive.domain = "test.local"` → `forge.test.local`,
  `ROOT_URL = http://forge.test.local/`, vhost present
- `forge.domain = "git.example.com"` → `git.example.com`,
  `ROOT_URL = http://git.example.com/`, vhost = `["_", "git.example.com"]`
- `gateway.enable = false` → `forge.domain` falls back to `localhost`,
  `ROOT_URL = http://localhost:3000/`, no gateway vhost
  (`behindGateway = false`)
- `/etc/hosts` (when `localHostsEntry = true`) → unique entries for
  hive-domain + forge.domain (de-duped via `lib.unique` for the
  edge case where forge.domain = hive-domain)
- full container toplevel builds clean

## PR title

(Will fix the PR title separately — still says "/forge/" which is
wrong since the rewrite to sub-domain shape.)

f037056015 nix/hive-{forge,gateway}: move forge to forge.<hive-domain> sub-domain (#749, mara verdict)
mara on #749:9609: "we will go with sub domains for forge and matrix
(redirected in well known in the latter case, not user visible). close /
fix PRs you have open that dont match this."

Reshapes the v1 sub-path (`<host>/forge/`) approach into a sub-domain
vhost (`forge.<host>/`) per the mara verdict. matrix gets the same
treatment in damocles's #751 follow-up.

## Why sub-domain

- forgejo's default `ROOT_URL = http://<host>/` works without any
  `X-Forwarded-Prefix` gymnastics — sub-domain hosting is the
  canonical Forgejo deploy shape, matches every upstream-doc example.
- Cookie / storage isolation between the dashboard and forge (XSS blast
  radius shrinks; a future forge XSS can't reach dashboard session).
- matches the matrix-spec pattern that #751 wires up for the
  homeserver.

## Mechanics

**forge options:**
- `services.hyperhive.forge.subdomain` — nullable str, default `"forge"`
  → rendered sub-domain is `forge.<hive-domain>`. Set to `null` to opt
  out (forge stays direct on `httpPort`); set to `""` for bare-domain
  landing (advanced, collides with dashboard).
- `services.hyperhive.forge.rootUrl` — nullable str override. When
  null, auto-derived: `http://<subdomain>.<hive>/` when gateway is on
  + subdomain set, else `http://<domain>:<httpPort>/` (direct).
- **Asserts** rootUrl ends with `/` (argus 🟡 on #754: forgejo's
  ROOT_URL contract requires trailing slash, else emits
  `https://forge.example.com.user.id` shaped garbage). Asserts
  `subdomain != null` requires `hyperhive.domain` set.

**gateway:**
- New `virtualHosts."<subdomain>.<hive-domain>"` server block —
  separate from the `"_"` catch-all. Proxies all `/` →
  `http://127.0.0.1:<forge.httpPort>/` so forgejo handles requests at
  root (no prefix translation needed; matches the upstream-default
  ROOT_URL shape).
- Git-tuned: `client_max_body_size 1G`, `proxy_read_timeout 1h`,
  `proxy_send_timeout 1h`, `proxy_buffering off`,
  `proxyWebsockets = true`. SSH stays direct on `cfg.sshPort`.
- `networking.hosts` (when `localHostsEntry = true`) now also adds
  `forge.<hive-domain> -> 127.0.0.1` for the dev loop.

## Verified

- `nix eval ROOT_URL` → `http://forge.test.local/` (default with
  gateway on)
- `nix eval ROOT_URL` with `gateway.enable = false` → `http://localhost:3000/`
  (current direct shape preserved)
- `nix eval virtualHosts attrs` → `["_", "forge.test.local"]`
- `nix eval networking.hosts` with `localHostsEntry = true` →
  `{"127.0.0.1": ["test.local", "forge.test.local"], ...}`
- bad rootUrl (no trailing /) triggers assertion at toplevel build
  with the spelled-out forgejo failure mode
- full container toplevel builds clean
  (`nixos-system-hive-gateway-26.05pre-git`)

## Migration

ROOT_URL change is a one-way migration on rebuild:
- Existing agent `git remote origin` URLs (`http://localhost:3000/...`)
  **keep working** — forgejo accepts any inbound URL; the URL on the
  agent side is unchanged.
- New clone-link copy-paste from forge UI uses `forge.<hive>/...` —
  operators copying clones after this lands need to go through the
  new sub-domain.
- Direct browsing on `:3000` shows pages with `forge.<hive>` links →
  works if hosts entry / DNS resolves, broken otherwise. Operators
  should switch to `http://forge.<hive>/`.

## Out of scope

- TLS termination (mara explicit on #15: no TLS v0)
- SSH-over-HTTPS / wildcard cert provisioning
- matrix sub-domain (damocles's #751, sibling work)

Closes #749. Addresses argus 🟡 on #754.
