Closes the queue task 7685 remainder of #812 (presence counts + public world directory feed on the shared directory_json serializer). Slice 1 (shared serializer, honest loaded field) landed as PR #1808.

What

• Presence counts: WorldInfo gains presence — the hub's live session lease count for that world (0 for stored worlds). WorldHub::list() fills it from the slot lease counters (read-only, no world is opened). directory_json emits "presence" per world. Per Drew's 2026-10-29 shape ruling on id phase-10: the world directory feed was not built — id world list --json is admin-only, has no presence counts, and 'open' means loaded-in-memory #812, the directory carries a count only, never an identity — who is present is not directory data, and nothing here writes us into a corner on making more private later.
• Public directory path: new ClientFrame::Directory (wire {"type":"directory"}) answers ServerFrame::Worlds with no admin token. The auth boundary is deliberate and documented on the frame: directory metadata only (names, loaded state, default, presence counts); the frame creates and opens nothing. The admin ListWorlds frame is unchanged.
• Client/CLI: WorldClient::directory() added; list_worlds shares the reply parser and now also returns presence. id world list: --admin-token is now optional — without it the CLI reads the public directory, with it the admin listing. The plain row shape is byte-unchanged (the id(world): world list plain output renders host-supplied names raw — a newline in a world name forges extra rows, and a tab forges columns #3089 two-field contract); presence shows in --json and the web UI.
• Web: the home world explorer now renders from directory_json (the shared serializer, same shape as id world list --json) and shows "N active" when a world's presence count is non-zero.

Auth-boundary decision (recorded per packet)

The directory is public read-only metadata on a mostly-public server (2026-10-29 ruling framing). Exposed: world names that the host serves, whether each is loaded, the default world's name, and live-session counts. Not exposed: user IDs, pseudonyms, true names, or which user is in which world — per-user visibility remains tracked on #812 (design, excluded from this packet).

Tests (laptop, pkgs/id)

• cargo test --lib directory_ — 79 passed (incl. updated directory_json_shape_names_loaded_not_open asserting presence, and new directory_frame_lists_worlds_without_an_admin_token proving the public frame answers with no token).
• cargo test --lib world_hub:: 15 passed; world_session:: 57 passed; web:: 128 passed; cli:: 11 passed; commands::world suite passed — 0 failures anywhere.

Remaining on #812 after this: per-user visibility toggles / true-name opt-in plumbing (design, explicitly excluded).

Codex findings gate — disposition (task 7685, lane code-e resume)

The Codex code review on this PR failed to run: the chatgpt-codex-connector[bot] summary records status failed for commit 4007821a8, and its follow-up comment states the Codex usage limits for code reviews have been reached. There are zero inline Codex findings and zero Codex review threads on this PR — nothing was raised, so there is nothing outstanding to fix or rebut. The has_unresolved_findings flag in the review-state marker reflects the failed run, not an actual finding.

Disposition: no findings to address. Merge proceeds under the standing criteria — the production line limit (2500) check is SUCCESS, the PR is mergeable/clean, and the laptop targeted tests recorded on task 7685 passed (211 passed, 0 failed across the world_hub / world_session / web::home / commands::world / cli filters, including the new public-directory tests).
