 ## Change Tracking with `log.md`
 
-Every OKF bundle has a `log.md` file. It is not optional. It is the bundle's memory.
+Every OKF bundle has a `log.md`, and it is the bundle's **only** work log: one file,
+at the bundle root. A subdirectory never gets its own — not `core/log.md`, not
+`notes.md`, not a per-project, per-branch or per-run diary. Sprawl is not caution:
+with fifty logs the entry is never where the next agent looks, and each copy re-dates
+the same event on its own authority. `scripts/kb-lint.sh` reports any `log.md` that is
+not the root's.
 
-**Format:** Date-grouped entries, newest first. One line per change with timestamp, file path, and what changed.
+**Format:** one dated section per day, newest first; a few lines per change — what
+happened, and the durable lesson. It is not a file manifest.

 # Bundle Change Log
 
-## 2026-01-15
-- `/docs/ghostty.md` — Updated keybind table after v1.2 release
-- `/docs/pi-permission-system/` — Added `policy.md` and `audit.md`
-- `/docs/index.md` — Synced with directory contents
+## 2026-01-15 — the gate was reading the wrong files
+
+A gate that gets an empty file list reports success. Law: a check MUST fail closed;
+a silently-passing gate is worse than none, because it buys the belief of safety.
+Details: [secret gate](../tools/index.md).
 ```
 
 **Rules:**
-- **Newest entries first.** Putting old entries at the top inverts the timeline and makes it impossible to see what just happened.
-- **One line per change.** A single line is sufficient. The git history is there if someone wants the gory details.
-- **Group by date.** Batch all changes from the same day together.
-- **Always date-stamp the section.** Use `## YYYY-MM-DD`.
-- **Mention `index.md` whenever you change a bundle.** If you added or removed a file, update the index and note it in the log.
+- **Newest entries first.** Old entries at the top invert the timeline.
+- **What changed + the durable lesson, a few lines.** Full narratives are recoverable
+  from git (`git log --follow log.md`); never re-expand one in place.
+- **Laws and incidents, never bookkeeping.** No per-file inventories, no run-by-run
+  numbers, no transcripts. Measured numbers still have to pass the purpose test.
+- **Link, do not duplicate.** Knowledge that outlives the entry belongs on its concept
+  page; the entry points there.
+- **One dated section per day** (`## YYYY-MM-DD`), and mention `index.md` whenever a
+  file is added or removed.
 
 ### Common Mistakes
 
-- ❌ Writing `"Updated ghostty.md"` — Updated it with what? Be specific.
-- ❌ Forgetting to write to `log.md` — This is the equivalent of doing surgery without keeping a record.
-- ❌ Using relative paths — Use absolute paths (`/docs/ghostty.md`).
-- ❌ Leaving stale entries from manual edits — The log is the single source of truth.
+- ❌ `Updated ghostty.md` — updated it with what, and what did it teach?
+- ❌ Forgetting the entry — the change lands undocumented and the next agent rediscovers
+  the failure the hard way.
+- ❌ Starting a second log in a subdirectory — the sprawl that makes logging useless.
+- ❌ Invented absolute paths in links — links resolve relative to the page, and the
+  linter checks them.
+- ❌ Re-expanding an old entry in place — the entry is a pointer; git is the transcript.

+## Quarantine, Not Deletion
+
+A page is never deleted outright: it moves to `.AGENTTRASH/` beside where it lived and
+waits for a pruning session with Frank present. The quarantine is not part of the
+bundle — `scripts/kb-lint.sh` and `scripts/kb-coverage.py` skip any path containing
+`.AGENTTRASH`. That exemption is deliberate: a gate that goes green only once the
+quarantined copy is gone is a gate that deletes history.
