Layer 1 keystone. The internal/inbox package writes ping-shaped JSONL
events to recipient inbox files in a format bit-identical to the
agent-ping CLI's output, so the existing UserPromptSubmit hook and the
future MCP Watcher cannot tell whether a line came from `ping` or the
Collector.
- O_APPEND opens for atomic line writes (POSIX guarantees writes <=
PIPE_BUF, our lines are well under).
- Per-recipient sync.Mutex bounds contention; multiple goroutines
writing to one inbox stay correctly serialized.
- 7 tests passing: shape, ID/TS preservation, omitempty for optional
fields, key-set + compactness match against ping CLI's separators=
(",",":") output, 100-goroutine concurrent-write torn-line check,
bad-input rejection, empty-dir rejection.
go.mod at git.botbought.ai/foreman/agent-watcher; module name matches
the public Forgejo path so eventual consumers can `go get` it.
Next milestones:
- Source plugin interface
- Drop folder source (inotify, via fsnotify)
- HTTP webhook source
- Config loader (YAML)
- main.go wiring
- systemd unit
