9d816431dc fix(#981): validate runner credentials on every boot, purge stale .runner
hive-ci-register.service now runs unconditionally on every boot (not
just when .runner is absent). Before fetching a registration token it
validates existing .runner credentials via the forge admin API:
- 200: runner still registered, write dummy token and exit
- 404: runner deleted from forge, purge .runner and re-register
- 000: forge unreachable, keep credentials (runner surfaces the error)
- other non-200 or malformed .runner: purge and re-register

Removes ConditionPathExists so stale credentials from a wiped forge
no longer block the runner indefinitely. Updates docs/ci.md to match.

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.

ba1d096391 fix(gateway): interpolate actual htpasswdFile path in 401 page
Per argus review: the hardcoded /etc/hyperhive/gateway.htpasswd
example was wrong for operators with a custom htpasswdFile path.

Move the unauthorized.html from the static agentErrorPagesDir derivation
into a pkgs.writeText inside the lib.optionalAttrs guard where
cfg.auth.htpasswdFile is in scope and statically known non-null.
The rendered page now shows the operator's actual configured path.

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.

db50da570a refactor(#1003): nixpkgs + nixpkgs-unstable as top-level meta inputs
Per mara's direction: both nixpkgs and nixpkgs-unstable are now
top-level meta flake inputs with explicit store-path URLs.  Hyperhive
follows them rather than the other way around:

  inputs.nixpkgs.url            = "path:${pkgs.path}";
  inputs.nixpkgs-unstable.url   = "path:${nixpkgs-unstable}";
  inputs.hyperhive.url          = "...";
  inputs.hyperhive.inputs.nixpkgs.follows            = "nixpkgs";
  inputs.hyperhive.inputs.nixpkgs-unstable.follows   = "nixpkgs-unstable";

New NixOS host options (auto-set at build time, overridable):
  services.hyperhive.c0re.nixpkgsFlake
    default: "path:${pkgs.path}" — host's evaluated nixpkgs.
  services.hyperhive.c0re.nixpkgsUnstableFlake
    default: "path:${nixpkgs-unstable}" from hyperhive's flake.nix —
    the channel that carries claude-code.  Operators can override to
    track a different unstable snapshot.

Legacy fallback (both args empty) preserved for backward compat.
Two new Rust tests cover the full-URL and fallback paths.

fe5a41288d feat(#1003): inject pkgs.path into meta flake as explicit nixpkgs.url
meta flake was using `nixpkgs.follows = "hyperhive/nixpkgs"` but
`hyperhive` is a store-path input, so nix resolves hyperhive's own
pinned lock rather than the host's follows-substituted version.
When an operator sets `inputs.hyperhive.inputs.nixpkgs.follows =
"nixpkgs"` in their host flake, the meta flake was silently ignoring
it and using hyperhive's pinned nixpkgs instead.

Fix: hive-c0re.nix injects `--nixpkgs-flake path:${pkgs.path}` into
the daemon's ExecStart. `pkgs` IS the host's nixpkgs when follows is
set; otherwise it's hyperhive's own pin — so the meta flake gets the
right nixpkgs in both cases. render_flake emits `nixpkgs.url = "..."`
(explicit) when nixpkgs_flake is non-empty, falling back to the old
`follows` form when empty for backward compat.

4bff450343 feat(gateway): hivectl gateway user management + fix htpasswdFile assertion
Add `hivectl gateway {create-user,delete-user,list-users}` subcommands for
managing htpasswd files used by gateway Basic auth. Pure Rust bcrypt
(cost 12, $2y$ prefix nginx accepts). No external htpasswd binary required.

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.

Update docs/gateway.md to show hivectl commands instead of raw htpasswd.

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).
See `docs/gateway.md` ("HTTP Basic auth") for the full setup guide.

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.

e162c1a1fa feat(#955): split agent page serving — statics from nix store, API proxied
gateway_nginx.rs reads HIVE_AGENT_FRONTEND_DIR (injected by hive-c0re.nix
as ${cfg.frontend}/agent). When set, agents.conf emits per-agent split
blocks instead of the old single proxy_pass:

  # Compiled assets — immutable nix store path, cache 1y
  location ^~ /agent/<name>/static/ {
      alias <frontend>/static/;
      expires 1y; add_header Cache-Control "public, immutable, ...";
  }
  # Static dist + proxy fallback
  location /agent/<name>/ {
      alias <frontend>/;
      try_files $uri $uri.html $uri/index.html @<name>_dynamic;
  }
  location @<name>_dynamic {
      proxy_pass <upstream>;   # api, events, icon, login, …
      …proxy headers unchanged…
  }

try_files path resolution (nginx applies alias mapping first):
  $uri           — exact file (/static/app.js → static/app.js)
  $uri.html      — bare-path fallback (/stats → stats.html)
  $uri/index.html — directory index (/ → index.html)
  @<name>_dynamic — proxy catchall for anything not in the dist

Adding pages to the frontend dist works automatically — no generator
change needed. Per-agent extraFiles (in mergedDist, not in the base
nix-store path) continue to proxy to the agent daemon.

frontend is a nix store path injected at build time — only [a-z0-9/._-],
no shell metacharacters — safe to interpolate without sanitization;
comment added documenting this assumption.

Without HIVE_AGENT_FRONTEND_DIR the existing single-proxy block is
emitted unchanged — backward-compatible for deployments without the env.

render() takes frontend_dir as a parameter so tests exercise both code
paths safely in parallel. 13 tests: 7 legacy, 6 split-mode. No clippy
warnings in changed files.

84f5c2722e nix(#702): add hive-priv systemd socket + service units
Nix side of the hive-priv phase 1 work. hive-priv is socket-activated
exclusively: systemd holds /run/hive/priv.sock (mode 0660) and starts
the service on first connection. LISTEN_FDS + LISTEN_PID are passed;
hive-priv reads them in socket_listener() to accept the pre-bound fd.

Phase 2 note (comment in file): when hive-c0re drops to a non-root
user, add SocketGroup = hive-core to the socket unit so the
unprivileged caller can still connect. No code change needed in
hive-priv itself.

f8c0f64fd4 feat: socket-activate the hive-c0re admin socket
Add a systemd.sockets.hive-c0re unit that holds /run/hyperhive/host.sock
before hive-c0re starts. hive-c0re serve() detects LISTEN_FDS via the
listenfd crate and accepts the systemd-handed fd instead of calling bind().
Falls back to the existing bind path when LISTEN_FDS is absent so direct
invocation and CI are unaffected.

Benefits: hivectl can connect the moment the socket unit activates (no
racy window), and a hive-c0re restart never drops the socket inode.

f0bd572b35 fix: correct runner registration ordering — oneshot + tmpfiles
The nixpkgs gitea-actions-runner module uses tokenFile as a systemd
EnvironmentFile, loaded before any ExecStartPre. Our previous
ExecStartPre override was too late — file didn't exist yet.

Fix: tmpfiles pre-creates /run/hive-ci/runner-token with a placeholder
on every boot. A new hive-ci-register.service oneshot (gated on
ConditionPathExists=!/var/lib/gitea-runner/hive/.runner) fetches the
real token and overwrites before gitea-runner-hive.service starts,
wired via After/Wants. On subsequent boots the placeholder is harmless
— nixpkgs register step exits early when .runner already exists.

Closes #918.

bf350df442 fixup: hive-ci auto-registers runner via forge admin API
Removes the manual runnerTokenFile operator step. On first boot the
container fetches a runner registration token from Forgejo's admin
API using hive-c0re's existing admin token
(/var/lib/hyperhive/forge-core-token). A preStart script writes the
token to /run/hive-ci/runner-token; on subsequent boots it writes a
dummy (registered .runner creds take precedence anyway).

Operator bootstrap is now just `services.hyperhive.ci.enable = true`.

aa7ebbcd3b feat: add hive-ci module — Forgejo Actions runner for CI
Adds `services.hyperhive.ci` NixOS module that spins up a `hive-ci`
nixos-container running `gitea-actions-runner` against the hive-forge
Forgejo instance. Off by default; opt in with `ci.enable = true` after
generating a runner registration token in Forgejo.

Also adds `.forgejo/workflows/ci.yml` with four jobs: nix flake check,
formatting (nix fmt + cargo fmt), cargo test, and cargo clippy. Jobs
target the `hive-ci` runner label.

Container design mirrors hive-forge (shared host netns, non-ephemeral
state, loopback reach to forge). sandbox-fallback = true since nspawn
containers can't create user-namespaces for nix sandbox.

Closes #175.

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.

  injection comments (three near-identical blocks) — collapsed to

  detail already lives in `docs/gateway.md::Vhost map`.
- Dropped the trailing "Matrix GUI static serving lives entirely

fbc41d42a6 dashboard: build same-origin /agent/<name>/ links when gateway is up (closes #842)
When `services.hyperhive.gateway.enable` is on (default), the c0re
NixOS module now sets `HIVE_GATEWAY_ENABLED=1` on the service env.
`/api/state` exposes the flag as `gateway_enabled`; the SW4RM tab's
container-row renderer flips three link sites (primary agent-name
link, favicon fetch, `container`-kind nav-strip links) from the
legacy `http://<host>:<port>/` direct TCP shape to same-origin
`/agent/<name>/` URLs — the gateway proxies them to the per-agent
harness via `agent-ports.json` or `agent-sockets.json` (#784 / #815).
Gateway-off deploys keep the direct TCP fallback so local-dev /
operator opt-out keeps working.

`forge`-kind nav-strip links still resolve against `:3000` (separate
sub-domain transition, tracked by `forge.behindGateway`);
`external`-kind links are already absolute.

Mirrors the `HIVE_MATRIX_GUI_ENABLED` env→snapshot-flag pattern.

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.

a8d8159038 docs/matrix.md: extract hive-matrix prose (#718 batch 5)
New top-level matrix doc covering everything that doesn't fit
elsewhere:

- Container shape (nixos-container, shared host netns, name choice,
  state persistence) — sibling to gateway.md::hive-forge container shape.
- Identity vs API listener: serverName vs gatewayHost split with the
  #660 breaking change.
- Default-closed firewall + federation port 8448 caveat.
- Provisioning flow: registration token activation, bind-mount,
  LoadCredential, hive-c0re's per-agent register + access_token
  persistence. Captures #565 first-boot race + #644 / iris 8043
  ownership shape.
- Assertion rationale (serverName, gatewayHost == "").
- fluffychat-web build fixes (#685): Imaging.{js,wasm} emscripten
  derivation + dart compile worker fixup, build-CWD path lesson
  from #685 / #733.
- Sequencing history.

In-code # comments trim to short purpose statements + docs pointers.
description = '' blocks (operator-facing options docs) preserved per
iris #718. ~140 lines removed from hive-matrix.nix.

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

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.

ea90814809 docs/gateway.md: extract hive-c0re + hive-forge prose blocks (#718 batch 2)
Continues #718 docs-extraction. Three more blocks moved to
`docs/gateway.md` (which already houses the gateway architecture
story from #775):

1. **Firewall posture (gateway on vs off)** — was a 22-line block
   above `networking.firewall = lib.mkIf ...` in hive-c0re.nix.
   Trimmed to 3-line ref. New `docs/gateway.md::Firewall posture
   (host-level)` section covers the gateway-on / gateway-off
   trade-off + why dashboard port stays loopback-only.

2. **`HIVE_FORGE_URL` loopback rationale** — was a 14-line block
   above the env-var assignment. Trimmed to 5-line ref. New
   `docs/gateway.md::HIVE_FORGE_URL: loopback for in-cluster,
   sub-domain for the operator` section covers the in-cluster vs
   external split + why agent containers can't use the sub-domain.

3. **hive-forge container shape** — was a 15-line top-of-`config`
   block in hive-forge.nix explaining the nixos-container + host
   netns choices. Trimmed to 4-line ref. New
   `docs/gateway.md::hive-forge container shape` section captures
   the same content with state-dir + wipe-via-destroy notes.

Net: hive-c0re.nix -29 lines, hive-forge.nix -11 lines, gateway.md
+44 lines. Same pattern as #782 (first pass) per iris's #10114
guidance — substantive WHY moves to docs as named sub-paragraphs,
in-code shrinks to `// see docs/<file>::<section>` refs.

Verified: `nix eval` on agent-base toplevel still resolves
cleanly; firewall posture unchanged (still 0 ports opened in the
gateway-on case + the same 8100..8999 range in the gateway-off
case).

Continues #718. Follow-up batches: remaining harness-base.nix
blocks, nix/docs/default.nix, nix/assets.nix, nix/templates/weston-vnc.nix.

8d25b087b6 nix/hive-matrix: trim option-description prose to docs/gateway.md refs (argus #775 🔴)
argus on #775 v3: "the `gatewayHost` option description's
server_name-vs-gatewayHost essay + federation SRV note are also
candidates for [docs/gateway.md] section."

Cuts the gatewayHost option's description from ~40 lines (with
inline duplication of the discovery flow, when-to-set-which, and
federation port caveat) down to ~8 lines pointing at
`docs/gateway.md`. The brief `server_name vs gatewayHost` clarifier
stays in code because it disambiguates two SIMILAR-LOOKING options
on the same module — operators reading option docs need the
distinction inline, not behind a doc link.

Also trimmed `matrix.gui.enable` + `matrix.gui.package` descriptions
to similar shapes — point at docs/gateway.md for the architecture,
keep the override-shape hints in code.

Push includes the rebase onto current main (#764 + 0af6ea1 + others
landed since #775 was opened; cherry-picked commits get skipped
cleanly).

Net: matrix.nix loses ~70 lines of inline prose. No behavioral
change (verified gatewayHost still resolves to `matrix.<hive>`).

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.
