`hermes webhook subscribe` has no --toolsets flag, so a webhook run got
Hermes's constrained default (web_search, web_extract, vision_analyze,
clarify) -- no shell, no file access, which meant neither prompt could
actually be carried out: luna was woken, read the comment, and had no way
to act on it. Upstream's documented answer is to add the `toolsets` key to
webhook_subscriptions.json by hand, and a hand edit does not survive this
unit's re-provision. So the whole route definition moves here and the CLI
is not used at all.
The file is written host-side with jq. hermesHome is the bind-mount source
for /opt/data, so the container sees the same inode and hot-reloads it on
the next delivery -- no podman exec, no readiness loop, and no quoting
chain between nix and the prompt text. The merge is per-route: routes this
unit does not name survive, created_at is carried over, and every other
key is replaced outright so a hand-added `deliver_only` or `filters`
cannot linger.
The secret now comes from the sops file directly instead of being read
back out of the container's environment, which drops podman-hermes-agent
from restartUnits (the ordering constraint it existed for is gone) and
takes GITEA_HERMES_WEBHOOK_SECRET out of an env var luna can read.
The new gitea-pr-reviews route covers reviews with a body and
changes-requested. Those are not IssueCommentPayloads: gitea sends a
PullRequestPayload with action "reviewed" and a `review` object of exactly
{type, content} -- no review id, no line comments. So the prompt fetches
them with `tea pulls review-comments` and acts only on ones whose
`resolver` is empty, resolving each as it goes; with no stable id in the
payload, resolved state is the only workable duplicate-delivery guard.
An empty review body is deliberately NOT a drop, unlike in the comment
filter: a review whose substance is entirely in line comments has none.
Approvals are left unsubscribed -- an approval is darman signing off, not
asking for work.

The relay existed on the premise that Gitea sends no header Hermes can read
an event name from, so something had to copy X-Gitea-Event into
X-GitHub-Event. That premise was wrong. Gitea's addDefaultHeaders sets
req.Header["X-GitHub-Delivery"] = []string{t.UUID}
req.Header["X-GitHub-Event"] = []string{event}
req.Header["X-GitHub-Event-Type"] = []string{eventType}
unconditionally, for every webhook type, alongside X-Hub-Signature-256 in
GitHub's exact format. (Direct map assignment rather than .Add() specifically
to keep the "GitHub" casing that canonicalisation would destroy.) Hermes
validates that signature on any route without provider gating and reads the
event name from that header, so gitea and hermes already speak the same
protocol and the translation layer was translating nothing.
Gitea now posts straight at http://mars.orbit.sol:8644/webhooks/gitea-pr-comments.
The URL path is the Hermes route name, so a second subscription is a second
hook and nothing else -- the route-in-path indirection the relay grew was a
reimplementation of something Hermes already had.
Removes the module, the 200-line relay, its test, the mars import, the 8645
listener, and the stale gitea-hermes-webhook-relay.service entry left in the
secret's restartUnits. hermes-agent-webhook-route moves to
hosts/mars/hermes-agent.nix, next to the container and the read-only prompt
and filter mounts it depends on.
Also makes that unit refuse to subscribe when GITEA_HERMES_WEBHOOK_SECRET is
unset in the container, matching the existing empty-prompt check. An empty
secret silently fails every delivery signature check afterwards while the
unit still reports success -- the worst possible failure shape, and one this
setup can actually produce on a first deploy.

The relay was forwarding X-Gitea-Event and re-signing the body into the
deprecated generic-V1 X-Webhook-Signature header. Neither is something
Hermes acts on, which left the PR's core premise — "Hermes owns event
selection" — impossible to reach:
- Hermes reads the event name only from X-GitHub-Event/X-GitLab-Event,
then payload event_type/type, then falls back to the literal string
"unknown" (gateway/platforms/webhook.py). Gitea sends X-Gitea-Event and
no such payload key, so every delivery arrived as "unknown" and
`hermes webhook subscribe --events ...` could never select anything.
- Gitea's addDefaultHeaders() already signs every webhook type with
X-Hub-Signature-256 in GitHub's exact format, and Hermes accepts that
header on any route with no per-route provider gating. Re-signing into
V1 was both redundant and on a deprecated path.
So the relay now verifies the signature (accepting either X-Hub-Signature-256
or X-Gitea-Signature), forwards body and signature byte-for-byte, and copies
the one header Hermes actually needs. Authentication alone never justified
this service; that header copy does, and the module comment now says so.
Also fixed:
- gitea-hermes-webhook-provision had no API readiness wait, unlike both
sibling units in the same file. After=gitea.service does not mean gitea
is serving HTTP, so under `set -e` a Type=oneshot with no Restart= would
fail on first boot and stay failed, leaving the webhook unregistered.
- podman-hermes-agent added to the secret's restartUnits. The secret
reaches the container only via sops.templates, whose rendered path never
changes, so systemd would not restart the container when the secret was
first added — hermes-agent-webhook-route then read an empty value back
out of it and subscribed with an empty secret.
- Webhook provisioning passes the request body to curl on stdin rather
than in argv, keeping the shared secret out of /proc/<pid>/cmdline.
- Missing Content-Length now returns 411 rather than 413; dropped the
unreachable non-2xx branch (urlopen raises on non-2xx); env-var secret
fallback is stripped to match the credential-file path.
Adds gitea-hermes-webhook-relay-test.py, which drives the real relay over
real HTTP against a stub Hermes and covers the header copy as a regression
test. Both nixosConfigurations still evaluate.

Provisions a dedicated PR-tier gitea account (luna) with branch protection
restricting master push/merge/approve to darman only, then wires git and
tea directly into the hermes-agent container (mounted from the host's Nix
store, credential-store + tea login set up by a host-side prepare oneshot,
repo cloned inside Hermes's own writable sandbox root at
/opt/data/workspace/homelab). Replaces an earlier standalone MCP-server
approach, scrapped in favor of direct CLI access for simplicity.

New on-site host mars runs Hermes Agent as its sole service: joins the
tailnet, mounts jupiter's samba share at /mnt/jupiter (doubling as
Hermes's shared dropbox), and hosts state locally under /var/lib/hermes.
Same Authentik OIDC app/Telegram bot as before, just relocated — neptun's
hermes.mgaction.town vhost now points at mars.orbit.sol instead of jupiter.
hosts/jupiter/hermes-agent.nix and its three sops secrets are removed;
jupiter's Caddy vhost for it is gone too. Also refreshes tailscale_authkey
across all hosts and fixes two stale "erik@laptop" keys in flake.nix's
kexec/installer-iso images (leftover from a previous laptop, already
swapped out of common.nix back in 2fd5752) to darman@terra.
