{"type":"remove","actor"} shuts the actor down normally, drops its
mailbox and supervisor, and deletes /actor/<id>/. Native actors cannot
be removed. Test in cli/tests/host.rs, documented in PROTOCOL.md.
File operations under /actor/<id>/fs/ become messages from `fs` to <id>
(fs_read, fs_write, fs_mkdir, fs_remove, fs_rename) with a 10 s timeout.
vfs.rs wraps the wasi:filesystem implementation of wasmtime-wasi.
- broker: `{"type":"exit"}` answers `exiting`; `sausage run` then stops all
actors and exits with code 75.
- flake: apps `loop` / `loop-internal` run `nix run --refresh git+ssh://.../surma/sausage -- run <world>`
in a loop; exit code 0 (/quit) ends the loop, anything else restarts.
- PROTOCOL.md, README.md, test in cli/tests/host.rs.
Not compiled: written by the Sausage agent, which cannot build the native host.
Staging every write until close broke tempfile, git, and SQLite, which
expect normal files. Actors that need an atomic publish write a temporary
file and rename it; the SDK has write_atomic for that.
Host:
- test first: a new version is tested where it lies; only an installed
version goes to versions/, and instances run from there
- data/ and public/ are shared by all versions; no snapshots; rollback
restores code only
- no re-delivery, status.json, list, remove/archive, smoke test, data/
hiding, or stdin timeout; rollback needs a version
- supervisor.rs split out; one place for installing a version
- init only writes the agent folder; run installs it like any actor
- console: @actor, text to the agent, /help, /quit
Agent:
- every text goes out as a broadcast; 5-line prompt; 5 tools that describe
themselves; turn.json only marks an active turn
Docs: PROTOCOL.md, README.md, DECISIONS.md, AGENTS.md rewritten.
Examples: only notes and notes-v2.
- one live instance per actor: check after the lock; dropping an instance kills it
- state snapshots keep target/ and .git/; only source copies skip them
- one shutdown deadline; output during shutdown is still routed
- deliveries route stdout meanwhile; a stuck stdin kills the instance
(no partial lines) and the sender gets undeliverable; control requests
are not blocked by a stuck delivery
- Host::stop aborts running broker and cargo requests first
- compile a version before installing it; roll back if it does not start
- unique archive names; a failed archive keeps the actor manageable
- commit on close: truncate without create; directory renames
- candidates see SAUSAGE_VERSION and the existing state of a new actor
- the host publishes PROTOCOL.md at /actor/broker/public/
