docs(ROADMAP): mark P1.2 and P1.4 as done

- P1.2: Cross-module integration tests — 12 tests landed
- P1.4: SummaryCompressor wiring — compress_summary_text() feeds
  into LaneEvent::Finished detail field

Both verified in codebase. P1.3 (lane-completion emitter) remains open.

 1. Isolate `render_diff_report` tests into tmpdir — flaky under `cargo test --workspace`; reads real working-tree state; breaks CI during active worktree ops
 
 **P1 — Next (integration wiring, unblocks verification)**
-2. Add cross-module integration tests — every Phase 1-2 module has unit tests but no integration test connects adjacent modules; wiring gaps are invisible to CI without these
+2. Add cross-module integration tests — **done**: 12 integration tests covering worker→recovery→policy, stale_branch→policy, green_contract→policy, reconciliation flows
 3. Wire lane-completion emitter — `LaneContext::completed` is a passive bool; nothing sets it automatically; need a runtime path from push+green+session-done to policy engine lane-closeout
-4. Wire `SummaryCompressor` into the lane event pipeline — exported but called nowhere; `LaneEvent` stream never fed through compressor
+4. Wire `SummaryCompressor` into the lane event pipeline — **done**: `compress_summary_text()` feeds into `LaneEvent::Finished` detail field in `tools/src/lib.rs`
 
 **P2 — Clawability hardening (original backlog)**
 5. Worker readiness handshake + trust resolution
