pkgs/id: .id-worlds/<name>/ world directory gitignored nowhere — journal, directory, petnames, outbox and modules one git add -A from commit #439

Finding

pkgs/id durable worlds live in a CWD-relative .id-worlds/<NAME>/ directory that is gitignored nowhere. Running id serve with a world from inside a repo checkout creates .id-worlds/<name>/ in the checkout, and most of its contents — the world's journal, directory, petnames, mail outbox, installed modules and records namespace — show up in git status, one git add -A from being committed. This is the same failure #420 and #432 fixed for the identity DB and for events.redb/groups.jsonl; the world directory as a whole was missed, and only two of its files happen to be covered by those basename fixes.

Evidence (verified on current main d3bba2d3)

• pkgs/id/src/commands/serve.rs:408,416-418: pub const WORLDS_DIR: &str = ".id-worlds"; and world_dir(name) returns PathBuf::from(WORLDS_DIR).join(name) — relative, no data-dir prefix of its own.
• pkgs/id/src/main.rs:82-87 (comment + code): all data paths are CWD-relative; the process only changes directory when --data-dir or --new is given. A plain id serve from a checkout therefore writes .id-worlds/ into the checkout. pkgs/id/src/cli.rs:387 documents: "The world's files live in .id-worlds/<NAME>/."
• World directory contents: pkgs/id/src/world_store.rs:321-346 opens journal.jsonl, directory.jsonl, petnames.jsonl, outbox.jsonl and modules/<blake3>.wasm under the world dir; pkgs/id/src/artifact.rs:50 puts artifacts.jsonl beside directory.jsonl; serve.rs (~line 574) adds records.namespace; the event store and group log add events.redb / groups.jsonl.
• git check-ignore on main d3bba2d3 — none of these is ignored:
  • .id-worlds/lobby/journal.jsonl -> NOT IGNORED
  • .id-worlds/lobby/directory.jsonl -> NOT IGNORED
  • .id-worlds/lobby/artifacts.jsonl -> NOT IGNORED
  • .id-worlds/lobby/petnames.jsonl / outbox.jsonl -> NOT IGNORED
  • .id-worlds/lobby/records.namespace -> NOT IGNORED
  • .id-worlds/lobby/modules/abc.wasm -> NOT IGNORED
  • Only events.redb (root .gitignore:120) and groups.jsonl (:122) are covered, by the repo-wide basename rules from pkgs/id: events.redb (event store) and groups.jsonl (group log) are gitignored nowhere — CWD-relative defaults leave them one git add -A from commit #432. Root .gitignore:117-122 has .iroh*, .identity.db, .identity.redb, events.redb, events.redb.tmp, groups.jsonl — no .id-worlds.
• Dedup: gh search issues "id-worlds" returns nothing; pkgs/id: .identity.db/.identity.redb only gitignored under pkgs/id/ — a serve run from any other in-repo directory leaves the identity DB one git add -A from recommit #420/pkgs/id: events.redb (event store) and groups.jsonl (group log) are gitignored nowhere — CWD-relative defaults leave them one git add -A from commit #432 cover different files and are closed.

Why it matters

A world's journal and directory are the world's durable state (inputs, installs, directory records, petnames, queued mail). Committing them by accident leaks that state into git history and bloats the repo with append-only logs and wasm modules — exactly the accident class #372/#420/#432 already had to clean up for the identity DB and event store. The partial coverage is worse than none in one way: git status still shows the directory, so the remaining files look deliberately tracked.

Acceptance criteria

• Root .gitignore ignores .id-worlds/ at any depth (mirroring the repo-wide .iroh* / events.redb entries from pkgs/id: .identity.db/.identity.redb only gitignored under pkgs/id/ — a serve run from any other in-repo directory leaves the identity DB one git add -A from recommit #420/pkgs/id: events.redb (event store) and groups.jsonl (group log) are gitignored nowhere — CWD-relative defaults leave them one git add -A from commit #432), so git check-ignore .id-worlds/<any>/journal.jsonl (and directory.jsonl, artifacts.jsonl, petnames.jsonl, outbox.jsonl, records.namespace, modules/*.wasm) succeeds.
• No tracked file lives under a .id-worlds/ path (verify with git ls-files | grep id-worlds — expected empty), so no git rm --cached is needed; if one exists, remove it from tracking in the same change.
• The existing id entries (.identity.db, .identity.redb, events.redb, groups.jsonl) are unchanged.

Suggested fix: add .id-worlds/ to the root .gitignore id block next to .iroh*.
