+# Release 15 — storage and build hardening
+
+`main` at `99d4d76a` (release 14's T1, H1 and H2 merged). No plan file of its own: each slice's
+prompt carries its ruling, and this record carries what was built. Rules:
+`plans/tools/implementer-rules.md`, with the commit trailer this release's prompts give.
+
+**The standing choices** (not re-opened):
+- **An unmounted drive is not an empty channel,** for any build that walks the pool. The stats
+  build already holds such a channel ([`stats-cache-key.md`](stats-cache-key.md)); the index
+  build gets the same hold here.
+- **A slice that needs another slice's file stops and says so**; it does not edit it.
+- **Nothing is edited in the primary checkout**; each slice has its own worktree, and the parent
+  merges with `git merge --no-ff` only on a clean tree.
+
+## The slices
+
+| Slice | Branch | What | Owns |
+|---|---|---|---|
+| IG | `r15/index-hold` | The index build holds an unreachable channel instead of emptying it | `common/controller/buildIndex.ts` + new `buildIndex.test.ts`, `common/controller/buildStats.ts` (the hold's words move to a shared module), new `common/lib/channelMediaHold.ts`, `common/bin/build-index.ts`, `common/lib/envVars.ts`, `ENVIRONMENT.md` |
+| DS | `r15/drive-stall` | A stalled drive does not stop the editor answering | per its prompt |
+| UT | `r15/umtool-trace` | umtool's build stops tracing the whole `umtool/` folder | per its prompt |
+
+**Order:** IG → DS. DS adds a health gate inside `inspectChannelMedia`, which IG's hold calls
+through its public signature. UT is independent. The shared files are `editor/CHANGELOG.md`'s
+`[Unreleased]` and this record.
