# Hive-wide knowledge repository
|
|
|
|
`internal/knowledge` on the forge is a shared reference doc repo
|
|
readable by every agent. hive-c0re clones it to the host and
|
|
bind-mounts the clone read-only into every agent container at
|
|
`/knowledge`.
|
|
|
|
## Agent access
|
|
|
|
Inside any agent container:
|
|
|
|
```
|
|
/knowledge/ # read-only bind-mount of the local clone
|
|
/knowledge/README.md # table of contents (seeded on first use)
|
|
```
|
|
|
|
Agents read documents directly from that path. The mount is
|
|
read-only — agents never write through it. To contribute, use the
|
|
`hive-forge` AGit flow (no fork needed — see
|
|
[Contributing](#contributing)); the operator reviews and merges, and
|
|
the local clone updates automatically (see
|
|
[Sync mechanism](#sync-mechanism) below).
|
|
|
|
## Repository layout
|
|
|
|
Canonical forge location: `internal/knowledge` (org `internal`,
|
|
repo `knowledge`). The repo is public, so every agent's forge account
|
|
has read access without an explicit per-agent collaborator grant;
|
|
only the `core` account has push access, for auto-seeding.
|
|
|
|
The repo is auto-created at hive-c0re startup if it doesn't exist,
|
|
seeded with a `README.md` containing a contribution guide and a
|
|
blank table of contents. Add an entry to that ToC each time you
|
|
create a new document.
|
|
|
|
## Sync mechanism
|
|
|
|
hive-c0re maintains the local clone at
|
|
`/var/lib/hyperhive/knowledge` via two paths:
|
|
|
|
1. **Forgejo push webhook** — `ensure_webhook` registers a push
|
|
hook on `internal/knowledge` at startup pointing at
|
|
`https://<hive_domain>/webhook/knowledge` (routed through the
|
|
gateway, avoiding the Forgejo SSRF guard that blocks loopback
|
|
delivery). On any push to main (including merge commits) hive-c0re
|
|
runs `git pull` so agents see the new content on their next turn.
|
|
The endpoint is protected by an auto-generated HMAC secret that
|
|
hive-c0re verifies on every delivery.
|
|
|
|
2. **Periodic pull** — a background task in `hive-c0re::main`
|
|
pulls on a fixed cadence as a fallback (webhook missed, c0re
|
|
restarted between pushes). The pull is best-effort — a failure
|
|
logs a warning and does not affect the rest of the daemon.
|
|
|
|
Both paths share the same `knowledge::pull()` function, which also
|
|
handles the change notice below — neither path can forget to wire it
|
|
in since the broadcast logic lives once, in `pull()` itself, not at
|
|
each call site.
|
|
|
|
### Change notice
|
|
|
|
When a pull actually moves the local clone's `HEAD` (a real change,
|
|
not a no-op — e.g. the periodic pull finding nothing new), hive-c0re
|
|
broadcasts a short notice to every currently-registered agent's inbox:
|
|
sender `system`, body `[system] /knowledge updated:` followed by a
|
|
`git diff --stat <old>..<new>` summary of what changed (or a generic
|
|
"see the repo" fallback if computing the diff itself fails). This is
|
|
the same broadcast mechanism used for other hive-wide notices — inbox
|
|
message only, no forced wake, and it carries the standard "this was a
|
|
broadcast" hint. A diff or per-agent send failure is logged but never
|
|
blocks the pull itself.
|
|
|
|
The local clone is created (or refreshed) once at startup via
|
|
`knowledge::ensure_local_clone`. If the repo is brand new and
|
|
empty, `ensure_local_clone` seeds it with the default README
|
|
before returning.
|
|
|
|
## State
|
|
|
|
- **Host clone**: `/var/lib/hyperhive/knowledge` — persists across
|
|
hive-c0re restarts and agent destroy/recreate. Deleted only by
|
|
manual operator action.
|
|
- **In-container mount**: `/knowledge` — bind-mounted read-only
|
|
from the host clone on every container start. Gone when container
|
|
is stopped; reappears on next start with the current clone state.
|
|
|
|
The mount deliberately **excludes `.git`**: the host clone embeds the `core`
|
|
token in `.git/config` (it rides the clone URL), so hive-priv overlays an empty
|
|
tmpfs at `/knowledge/.git` — agents see the documents, not the repo metadata or
|
|
token.
|
|
|
|
## Contributing
|
|
|
|
Agents have read access to `internal/knowledge` (it's public) but no
|
|
write access, so they can't push a branch directly. The supported path
|
|
is Forgejo's **AGit flow** through the `hive-forge` CLI — no fork
|
|
required.
|
|
|
|
1. Clone the repo (credentials are injected automatically; the `-r`
|
|
flag selects the repo, the clone lands in `./knowledge`):
|
|
|
|
```sh
|
|
hive-forge -r internal/knowledge clone
|
|
cd knowledge
|
|
```
|
|
|
|
2. Create a branch and add or update a document, then commit normally.
|
|
|
|
3. Open (or update) a PR with `--agit`. This pushes the current `HEAD`
|
|
to `refs/for/<base>/<topic>`, which Forgejo turns into a PR even
|
|
though you can't push a branch:
|
|
|
|
```sh
|
|
hive-forge -r internal/knowledge pr-create --agit \
|
|
--title "docs: add the X runbook" \
|
|
--topic add-x-runbook \
|
|
--body-file - <<'EOF'
|
|
What this document adds and why.
|
|
EOF
|
|
```
|
|
|
|
Re-running with the same `--topic` updates the open PR (it
|
|
force-pushes the AGit scratch ref). The base defaults to `main`;
|
|
in `--agit` mode the push goes to the `origin` remote that
|
|
`hive-forge clone` set up.
|
|
|
|
4. The operator reviews and merges. The webhook fires on merge; every
|
|
running container sees the updated content within seconds (see
|
|
[Sync mechanism](#sync-mechanism)).
|
|
|
|
Do **not** try to `git push` a branch directly — lacking write access,
|
|
it's rejected. The `--agit` flow above is the no-fork path that works
|
|
from any agent.
