 - 2026-06-15: tracker created. v1.7.96-alpha shipped. All 19 bugs filed as Gitea issues #8–#26. vps2 feature issues (G#3/5/6) deferred (no new features).
 - 2026-06-15: **B5 (LND CORS) ✅ DONE** — root-caused, both fixes implemented, verified on .116/.198/.103 (harness 4/4 each), committed `1db720af`, pushed to vps2 main. Will bundle into .97 (Gitea #12 to close on .97 ship).
 - Validation nodes: .116 + .198 (pw ThisIsWeb54321@). Runtime is podman (docker not in non-interactive PATH). Sideload binary → /usr/local/bin/archipelago + restart (containers survive on these nodes).
-- **NEXT: B1–B4 + B14 (cloud/federation/mesh priority block).**
+- 2026-06-15 (cont.): **B1,B2,B4 ✅** dedup+guard — committed `ed493106`, unit-tested 2/2, live .198 healthy. **B14 ✅** transport recording — committed `1c6dc153` (after build-repair: used private `crate::federation::storage::` path → E0603; fixed to re-exported `crate::federation::`). **B21 ✅** Tor/FIPS pill — committed `0801dd66`. All pushed to vps2 main; builds verified EXIT 0.
+- **Discovered B14b** (FIPS reaches only ~4/15 peers; rest genuinely Tor) and **B21** (pill) during the block.
+- ⚠️ LESSON: a backgrounded build "completed" notification does NOT mean success — grep the EXIT code before committing (a broken commit reached main once; repaired by 1c6dc153; no release cut from it → fleet unaffected).
+- **NEXT: B3 (peer media streaming — big), then B14b (FIPS reachability), then app-specific (B6,B7,B9–B13,B15–B19).** None deployed to fleet yet — all on vps2 main awaiting the .97 release after full .116/.198 + UI verification.
