4947037454 chore(nix): trim stale body from deprecated isolateContainers option doc
The option is a no-op (marked DEPRECATED — ignored); the Prerequisite,
Migration, and Rust counterpart sections all described the migration that
already completed. Strip to just the deprecation notice.

Also fix the bridgeIp description: 'once netns isolation lands' is past
tense — isolation is unconditional now. Rephrase to present tense.

78482cb624 nix: remove the non-isolated (shared-netns) mode
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).

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.

a2a96490d3 fix: assert gateway.enable when isolateContainers + forge.enable
isolated agents reach forge via http://forge.<domain> → nginx.
without the gateway there is nothing on port 80 to serve that
hostname. assert early rather than fail silently at runtime.

806d0e4a61 fix: use forge domain URL + open 80/443 for isolated agents
when isolateContainers=true, isolated agents have dnsmasq as their
resolver — forge.<domain> resolves to bridgeIp. route HIVE_FORGE_URL
through nginx on port 80 instead of exposing the raw forge port.

- HIVE_FORGE_URL: http://<forge.domain> when isolated (nginx proxies)
- bridge firewall: open 80+443 for agents to reach nginx (gateway)
- remove forge-specific httpPort rule (no longer needed)
- update docs/gateway.md + docs/network.md

per mara's review comment on PR #1150.

c97120f016 fix: forge URL + firewall for isolateContainers=true
When containers run in private netns (isolateContainers=true), host
loopback is unreachable so HIVE_FORGE_URL=http://127.0.0.1:3000 breaks.

- nix/modules/hive-network.nix: when isolateContainers is on + forge
  is enabled, open forge.httpPort on the bridge interface so agents
  can reach forgejo at bridgeIp:httpPort (forgejo binds 0.0.0.0)
- nix/modules/hive-c0re.nix: HIVE_FORGE_URL switches to bridge IP
  when network.enable && isolateContainers; loopback path retained
  when isolateContainers=false
- docs/network.md: add Forge access + Forge URL rows to effects table
- docs/gateway.md: rewrite HIVE_FORGE_URL section for both modes

c1b40ef819 network: fix dead assertion + document HIVE_NETWORK_SUBNET host-address
Two argus review fixups:

1. Move isolateContainers assertion to an unconditional `lib.mkIf
   cfg.isolateContainers` arm. The prior placement inside
   `mkIf (enable && isolateContainers)` was dead code — the assertion
   could never fire because both flags were already true by the time the
   block activated. Now `isolateContainers=true; enable=false;` raises
   a NixOS assertion error at eval time.

2. Add comment on HIVE_NETWORK_SUBNET noting it carries the host-side
   bridge IP (e.g. "10.42.0.1/24"), not the canonical network address
   ("10.42.0.0/24"). Rust consumer must normalize via bitwise AND before
   subnet membership checks or address arithmetic.

39b4c65922 network: add isolateContainers option for #14 netns isolation
Adds `services.hyperhive.network.isolateContainers` (bool, default
false). When enabled alongside `network.enable`, activates:

- IP forwarding + NAT masquerade so isolated agents reach the internet
- nftables DROP rule blocking bridge-subnet → loopback (defence-in-depth
  against compromised agent reaching the c0re dashboard)
- `HIVE_NETWORK_ISOLATION`, `HIVE_NETWORK_BRIDGE`, `HIVE_NETWORK_SUBNET`
  injected into the hive-c0re service env; the Rust lifecycle reads these
  to set `PRIVATE_NETWORK`, `LOCAL_ADDRESS`, and `HOST_BRIDGE` in each
  agent container's conf

Config block rewritten as `lib.mkMerge [...]` — the prior `lib.mkIf //
lib.mkIf` pattern was invalid nix (mkIf returns a tagged value, not an
attrset; // on it is a type error). See docs/network.md for full design.

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.
