iris 060f325716 docs: fix genuine passive-voice hits in docs/integrations
Sixth batch of the ongoing write-good.Passive pass (hyperhive#4042):
read all 52 hits across knowledge.md/github.md/matrix.md/forge.md in
context and rewrote 39 with a clearly nameable actor -- mostly
hive-c0re, forge_notify, or a specific fn named right there or a
sentence or two earlier. forge.md's notification poller is the
densest yet (19/20 hits rewritten): forge_notify is established as
the section's sole actor early and reused throughout, the shape
that's produced the highest catch rates all along.

Left 13 alone: the "no X is needed" negative-capability idiom (x2),
a container-lifecycle state descriptor ("when container is stopped"),
a false-positive tokenization ("read-only" split across a line wrap,
vale matches "is read" inside it -- not a real passive at all), the
"X can't be Yed" idiom, a generic "before the ids are minted" timing
clause with no natural actor to name, a room-join policy-state
descriptor, an "is enabled"/"is trusted" pair describing a config/
trust state (predicate-adjective-copula bucket, same family as
"is privileged" from an earlier batch), three "**X is required**"
bolded requirement-list labels (structural convention, not really
mid-sentence passives), and a contrastive "are shared" clause
mirrored against an active sibling clause exactly like
claude-invocation.md's "everything else is shared" from the
turn-loop batch -- left alone there for the same reason.

One sibling-inconsistency catch worth flagging: forge.md's merge-
racing-comment paragraph had two passive clauses ("is left off",
"is dropped") sitting next to a third, already-active clause
("appends nothing") in the same three-item parallel list -- rewrote
all three under one active subject (forge_notify) for consistency.

Verified via vale before/after: 52 -> 13 write-good.Passive hits,
exactly the 13 left alone above; error count and other warning
categories unchanged (still on TooWordy since #4097 hasn't merged to
this branch yet). Re-read every changed line in full surrounding
context after editing, matching the diff to intent before running
the final vale check.

# 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 autoseeding.
hive-c0re autocreates the repo at startup if it doesn't exist,
seeding it 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. **Swarm event** — the swarm controller holds the single push hook on
`internal/knowledge` (see `docs/swarm/README.md` § Swarm-wide forge
webhooks). On any push to main, including merge commits, it sends an
event to every hive over the swarm queue and each hive runs `git
pull`, so agents see the new content on their next turn.
A hive that's offline when the swarm controller sends the event
doesn't get it on reconnect — the periodic pull below is what closes that gap. One
hive briefly showing older `/knowledge` content than another is
expected, and resolves by itself within the fallback interval.
**don't add a per-hive hook.** A webhook has exactly one target
URL, so a second registration against the same repo doesn't add a
recipient — it takes delivery away from whoever registered first.
Earlier versions had each hive register its own; hive-c0re now
removes its own leftover at startup, so no operator step is needed
to migrate.
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 doesn't 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 — for example 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. hive-c0re logs a diff or per-agent send failure
without blocking the pull itself.
`knowledge::ensure_local_clone` creates (or refreshes) the local
clone once at startup. 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 (`hive-forge` injects credentials 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.
