- [x] H13 Notifications: per-thread mark read, filter by kind and repository, "participating" versus "watching".

  - **Storage.** `/admin/storage` lists each repository's size, loose objects and packs. Maintenance runs `oxy gc` (grace period kept, write lock held) on one repository or all, and is audited.
160 160 
  - Tested in tests/accounts.rs. Hub spec §6.3, §12.2. Deployed.

  - Earth's repositories can be maintained from /admin/storage now; I have not run it on Andy's data.

- 2026-09-28 H16 done (oxygenhub#14, closed by the change). Measured on Earth first (oxygenhub/docs/performance.md).
163 + 
  - The raw bytes of heavy files took 5 ms, but their pages took 196 to 428 ms: syntax highlighting, Markdown rendering, and above all the file's "last change", found by `log_for_path_in` rebuilding the state and reading every change on each view.
164 + 
  - Now cached, in memory-bounded LRUs keyed by content or by (state, path): rendered Markdown, highlighted files, last change and blame. Labels are still computed fresh.
165 + 
  - `?plain=1` takes the lean path.
166 + 
  - Warm views: spec.md 196 → 8 ms, repo/mod.rs 400 → 18 ms, state.rs 317 → 14 ms, blame 428 → 23 ms.
167 + 
  - Unit test for the LRU; browse test checks the second view hits the cache. Hub spec §16.3.
168 + 
  - Follow-up for oxy-core: `log_for_path_in` should reuse a loaded state instead of rebuilding it.
