+# 2026-09-22 Session Summary
+
+## [2026-09-22] Reset requested, then cancelled
+
+`/ckb-reset` was invoked. Ran Step 0 (clean tree, restore point `2c4d57a`) and
+the Step 2 inventory, which found this KB already effectively a clean template
+— 0 entity pages, 0 project scopes, 0 decision records, 0 graph edges, nothing
+in `raw/`, `outputs/`, `libs/`, `linked/` beyond `.gitadd` placeholders, no
+modules installed, no `src/`. The only tier-1/2 content was 3 `wiki/log.md`
+entries (the schema 1.5 migration trail) and one workload summary.
+
+**Nothing was deleted.** The typed confirmation was never given — the user
+moved on to merging and syncing instead. Flagged at the time: `main` was
+already a clean template at schema 1.4, and clearing the log would leave the
+scaffold declaring 1.5 with no in-wiki record of how it got there.
+
+## [2026-09-22] Merge and sync
+
+- Working tree was already clean; nothing to commit.
+- `main` was an ancestor of `graft-ideas`, so the merge fast-forwarded — no
+  merge commit, both commits preserved individually, no conflicts.
+- Pushed `main` (c998489 -> 2c4d57a) to **both** remotes: `origin`
+  (git.wierzbowa.cloud/michal/ckb) and `codeberg`
+  (codeberg.org/Valdec/llm-wiki-cascade).
+- Schema 1.5 and template 1.8.0 are now the published state on both.
+
+**Left alone deliberately:** branch `graft-ideas` (now identical to `main`,
+safe to delete whenever), and branch `feature/external-source-connectors`,
+which holds one commit (`f3dbce7`) not present on either remote and is
+unrelated to this work.
