 - `03e8748` Task 13 — `types/l1.ts` (+ai_build, IntakeOutcome/Result, NearMiss, TreeNode,
   NextNodeRequest/Result, L1Categories) + `api/l1.ts` (intake→IntakeResult; nextNode,
   escalations, getCategories, setCategories). nextNode body carries `node_text`.
-- `df7150f` Task 14 + `f483196` Task 15 were FIRST committed BROKEN (I misread eslint
-  EXIT=0 as a clean tsc; both had TS2305 missing-export + props-contract errors).
-  **`2cc7c83` repairs both** — verified `npx tsc -b` EXIT=0 (whole project) + eslint EXIT=0:
-  - `L1Dashboard.tsx`: minimal outcome-dispatch edit on the REAL page (matched/build→walker;
-    suggest→use-flow/build-new; out_of_scope→escalate-without-walk).

+- Tasks 14/15 took THREE commits because the flaky shell caused two broken commits
+  (`df7150f`, `f483196` had missing-export/props errors; `ad9c4c8` was committed with
+  TSC_EXIT=2 because I batched the commit with its own failing verification). The REAL
+  working fix is **`4d3e2f1`** — confirmed via single-value commands: committed
+  `L1WalkTreeVariant.tsx` has `advanceNode` (grep -c = 3), committed `L1Dashboard.tsx`
+  has `useSuggestedFlow` (= 2); and a sentinel-wrapped `npx tsc -b` returned TSC=0,
+  eslint=0 on the on-disk files before commit. What landed:
+  - `L1Dashboard.tsx`: outcome dispatch on the REAL page (matched/build→walker;
+    suggest→use-flow/build-new; out_of_scope→escalate-without-walk). Original
+    PageMeta/greeting/inputs/open-tickets layout preserved.
+  - `L1WalkTreeVariant.tsx`: real props `{session,onSessionUpdate,onDone}` +
+    ResolveModal/EscalateModal + header + transcript sidebar kept; added ai_build branch
+    that walks nodes via /next-node (passes node_text), disclaimer banner (`bg-warning/10`
+    — NOTE: `*-dim` tokens are NOT `--color-*-dim`; use `/10` opacity), terminal→modals.
     flow/proposal keep the Phase-1 synthetic path.
   - `L1WalkPage.tsx` unchanged (already routes ai_build → tree variant).
   NOT browser-verified (chromium can't launch here).
-- **Verified clean state: HEAD `2cc7c83`, working tree clean.**
+- **SHELL DISCIPLINE for resume:** single-value Bash commands (`grep -c`, `wc -l`,
+  `git rev-parse --short`, `git log -1 --format=%s`) are RELIABLE; multi-line
+  `{ echo; … } > file` blocks get GARBLED/interleaved. NEVER batch a commit with its
+  own verification — verify in a separate step and READ the result before committing.
