- Capture now keys off wl-paste's `CLIPBOARD_STATE`: `sensitive`
(password manager via `wl-copy --sensitive`, covers the old
x-kde-passwordManagerHint case) and `nil`/`clear` persist nothing;
`data` reads the content off stdin in the same event, so the
sensitive check and the read can't straddle a clipboard change.
A manual `--capture-once` with no CLIPBOARD_STATE falls back to
querying wl-paste directly, now wrapped in `timeout -k 2 5` so a
stalled offer can't block a capture process forever.
- Single-instance guard moves to `bread_utils::singleton` (flock) —
kernel-atomic, auto-released on death, no stale pid file.
- `ignore_rules::is_sensitive`: conservative best-effort heuristics
that skip copies which look like secrets even when unflagged —
PEM/OpenSSH private key blocks, `password:`-style lines, labelled
one-time codes, Luhn-valid card numbers, well-known token prefixes.
A convenience, not a security boundary.
- `bread.command.clip.pin` verb (payload `{id, pin?}`, pin defaults
true) → `set_pinned`, emits `bread.clip.pinned` / `.pin.failed`.
- Two independent `wl-paste --watch` loops (regular clipboard always
on; primary selection when `capture.primary`), each restarting with
2s→30s capped backoff and state-change-only journal logging.
- Image type is sniffed from magic bytes (PNG/JPEG) on the stdin path
and requested by actual offered type on the fallback path — a JPEG
is stored as `.jpg` / `image/jpeg`, not relabelled PNG.
- content_kind: a single line of prose that merely contains a keyword
("class is a concept") no longer classifies as code — it must look
like a statement.
- history.db and images/*.png are now created with 0600 permissions
(owner-only) instead of default umask, since clipboard history can
contain plaintext passwords/tokens.
- breadclipd never persists clipboard content flagged with the
x-kde-passwordManagerHint MIME type (the convention KeePassXC,
Bitwarden, etc. use to mark content they own).
- Replaced breadclipd's 500ms busy-poll loop (2-3 wl-paste forks per
cycle, forever) with wl-paste --watch, so it only reacts on actual
clipboard changes.
- Documented both behaviors in the README.
