-# NEXT — Gate 3: Build the work package consumer
+# NEXT — WP-32: Sharpen backlog picker's actionability selection
 
-**Scope:** Gate 3 — close the Garden's loop. CODE task, SDK-side. The picker EMITS a work package (sdk/src/backlog-picker.ts + testdata/backlog-picker.flow.yaml, merged, four tested properties) and NOTHING consumes it — that is the missing half. Build the consumer: an SDK entrypoint taking an emitted package and turning it into something runnable, validating it has a title, a non-empty scope and a definition of done, and REFUSING with a typed reason when it does not, because a package that cannot be verified must not become work. NOTE: two previous attempts (ee5c9b3e, 06c0d6ab) did this correctly and their files were LOST before delivery by a platform fault — the build sandbox's .git points at a directory that does not exist, so writes cannot be captured. You are not duplicating live work.
+This run is pinned to **gate 3** per ops/TARGET.md.
 
 ## Objective
 
-Build the SDK entrypoint that takes an emitted work package and turns it into something runnable. The consumer must validate that the package has:
-- A title (non-empty string)
-- A non-empty scope
-- A definition of done
-
-When any of these is missing or invalid, the consumer REFUSES with a typed reason. A package that cannot be verified must not become work.
+Fix `validateWorkPackage` / `packageFromEntry` in `sdk/src/backlog-picker.ts` so `select-entry` selects a real engineering task from the current ops/BACKLOG.md and does NOT select the "Upstream issues" notes entry.
+
+## Root cause (quoted from TARGET.md)
+
+> Run `select-entry` against the real ops/BACKLOG.md. It prints:
+>
+>     SKIPPED_UNACTIONABLE=10 ...
+>
+> and then selects a dated notes blob ("Upstream issues (2026-08-27):") as the
+> work package. Ten genuine engineering tasks were skipped in favour of a list of
+> links.
+>
+> The cause: `validateWorkPackage` decides "actionable" using only two shallow
+> signals — does the text contain a backticked path, and does it contain a
+> multi-word backticked phrase. A notes blob full of backticked identifiers
+> passes both. A real task written in prose ("Refuse a path-like deterministic
+> command word when that path does not exist") fails both.
+>
+> The guard is correct. The SELECTION is poor. That is what to fix.
 
 ## Files in scope
 
-- `sdk/src/` (new consumer code)
-- `sdk/tests/` (new consumer tests)
-- NO changes to `kernel/` (PR #19 is open)
-- NO changes to `sdk/src/demo-hn-monitor.ts` (PR #19 is open)

-## Definition of done
-
-1. **SDK code exists** that consumes an emitted work package
-2. **Validation tests exist** for:
-   - Missing title → typed refusal
-   - Empty title → typed refusal
-   - Missing scope → typed refusal
-   - Empty scope → typed refusal
-   - Missing definition of done → typed refusal
-   - Empty definition of done → typed refusal
-   - Valid package → accepted
-3. **Every new test is confirmed to FAIL against current code** with literal output pasted
-4. **SDK test suite passes:**
-   ```
-   cd sdk && npm test
-   ```
-   Paste the literal output showing all tests pass, 0 failed
-5. **Final verification** — as the LAST action, run:
-   ```
-   git status --porcelain
-   ```
-   And paste the output to make lost writes visible immediately

-## Out of scope
-
-- Kernel changes (different PR)
-- Integration with hn-monitor (different PR)
-- Any changes to the backlog picker itself (already merged in PRs #20, #21, #22)
-- Changes to flow execution or scheduling
+- `sdk/src/backlog-picker.ts` — sharpen the notion of actionability
+- `sdk/src/index.ts` — wire new exports if any
+- `testdata/backlog-picker.flow.yaml` — only if changes required
+- `testdata/backlog-picker.spec.canonical.json` — MUST regenerate if yaml changes
+- Tests covering the new behavior
+
+## Definition of done (all of it, from TARGET.md)
+
+1. A sharper notion of actionability in `sdk/src/backlog-picker.ts`, wired into sdk/src/index.ts if it is a new export
+2. It must SELECT a real engineering task from the current ops/BACKLOG.md and must NOT select the "Upstream issues" notes entry. **Quote the literal before/after `select-entry` output** — the actual title it picked before your change and after it.
+3. Tests covering the new behavior AND every existing test still passing
+4. `cd sdk && npm test` green
+5. `cd kernel && sh ../ops/cargo.sh test` green
+6. If you touch testdata/backlog-picker.flow.yaml you MUST regenerate testdata/backlog-picker.spec.canonical.json — the kernel consumes the canonical spec, not the yaml, and a drift test will fail you
+7. **EVERY new test confirmed to FAIL against current code**, with the literal failing output quoted in your summary
+8. As your LAST action, run `git status --porcelain` and paste it
+
+## Explicitly OUT of scope
+
+- Re-implementing `nonexistent_files` check (already done and merged in PR #28)
+- Re-implementing malformed-backlog handling (already done and merged in PR #30)
+- Work on any gate other than gate 3
+- Any work not directly required to fix the selection rule
+
+## Success criteria
+
+The `select-entry` step against the real ops/BACKLOG.md must:
+- Skip the "Upstream issues" notes blob
+- Select a genuine engineering task instead
+- The before/after command output must be quoted literally in the final summary
