-# NEXT — WP-GATE2-POLLER: Implement HN poller to make hn-monitor actually monitor
+# NEXT — WP-GATE3-BACKLOG-PICKER: First honest step toward Software Garden
 
-**Target gate:** Gate 2 (per ops/TARGET.md — this run is pinned to gate 2 only)
+**Target gate:** Gate 3 (per ops/TARGET.md — this run is pinned to gate 3 only)
 
-**Work package:** WP-GATE2-POLLER — Implement deterministic HN poller
+**Work package:** WP-GATE3-BACKLOG-PICKER — Build a flow that reads ops/BACKLOG.md and emits a structured work package
 
 ## Objective
 
-Implement a deterministic poller that fetches `https://hacker-news.firebaseio.com/v0/topstories.json`, takes the first few story IDs, and submits each through `Engine::submit_event` so hn-monitor wakes on real HN data with dedupe.
+Gate 3 per RFC-0001 §3 is "a relayflow can power a factory → Software Garden." The done-when is a labeled issue flowing to a reviewed PR end-to-end. ops/TARGET.md directs: "Do the SMALLEST honest first step, not the whole thing. Good candidate: a flow that reads ops/BACKLOG.md, picks one entry by a deterministic rule, and emits a structured work package."
 
-**Context from ops/TARGET.md:** PR #15 landed `testdata/hn-monitor.flow.yaml` and `kernel/relayflowd/tests/hn_monitor_integration.rs`, but the triggering event comes from test code, not Hacker News. Gate 2 is AMBER. **The previous run wrote a work package and no code — do not repeat that. This is a CODE task: write the missing poller.**
+**This is that smallest step**: a flow file that demonstrates gate-3 machinery (flows that build and improve other flows) without attempting the full discover→implement→review→merge DAG.
 
-**Current state:** The `Engine::submit_event` path exists and works (kernel/relayflowd/src/engine/wake.rs:19). The hn-monitor flow exists and the integration test proves event → wake → park works. **The only missing piece is the poller that fetches real HN data and calls submit_event.**
+## Current state
+
+- Gates 1 (GREEN) and 2 (AMBER, in progress) have working primitives on main
+- Gate 3 is RED (not started) per ops/SCOREBOARD.md
+- ops/BACKLOG.md exists with structured entries
+- No gate-3 flows exist yet
 
 ## Files in scope
 
-**New file to create:**
-- `kernel/relayflowd/src/engine/hn_poller.rs` — poller implementation
+**New files to create:**
+- `testdata/backlog-picker.flow.yaml` — the flow spec that reads ops/BACKLOG.md and selects one entry
+- `testdata/backlog-picker.spec.canonical.json` — canonical compiled spec (via `flows check`)
+- `sdk/tests/backlog-picker.test.ts` — test proving deterministic selection given the same input
 
 **Files to modify:**
-- `kernel/relayflowd/src/engine.rs` — add `mod hn_poller;` and `pub use hn_poller::HnPoller;`
-- `kernel/relayflowd/src/lib.rs` — re-export HnPoller if needed
-- New test file or extend existing test to prove offline operation with recorded payload
+- None required for the minimal step
 
 ## Definition of done (all three required per ops/TARGET.md)
 
-1. **A new committed source file** implementing the poller exists at `kernel/relayflowd/src/engine/hn_poller.rs` with:
-   - Fetch `https://hacker-news.firebaseio.com/v0/topstories.json` (returns `Vec<u64>` story IDs)
-   - Take first N IDs (configurable, default 5)
-   - For each ID, construct an `Event` matching hn-monitor's trigger pattern:
-     - `event_type: "hn.story_posted"`
-     - `payload` with at least `{"id": <story_id>, "type": "story"}` (matches pattern in hn-monitor.flow.yaml:9)
-   - Submit via `Engine::submit_event` with the hn-monitor spec
-   - Dedupe works: same story submitted twice yields `matched: true, deduped: true` on second call
+1. **`flows check` resolves the flow** — `testdata/backlog-picker.flow.yaml` passes preflight validation with exit 0
 
-2. **`cd kernel && sh ../ops/cargo.sh test` passes** including a test that exercises the poller offline from a recorded payload (no live network call in test). Test should verify:
-   - Parsing topstories JSON (`[41380628, 41378954, ...]`)
-   - Constructing events with correct structure
-   - Submitting through submit_event
-   - Dedupe behavior (second submit is deduped)
+2. **A test proves selection is deterministic** — `sdk/tests/backlog-picker.test.ts` demonstrates that:
+   - Given the same ops/BACKLOG.md content, the flow always selects the same entry
+   - The selection rule is deterministic and documented (e.g., "first non-done entry", "alphabetically first", or similar)
+   - The test verifies structured output (the work package emitted has required fields)
 
-3. **The run's diff contains real code outside ops/**: The poller must be substantive Rust code, not just documentation.
+3. **`cd sdk && npm test` green** — all SDK tests pass including the new backlog-picker test
 
 ## Implementation approach
 
-- **Deterministic and testable**: Use a trait or function parameter to inject the JSON source, allowing tests to supply a recorded payload instead of hitting the network
-- **Minimal scope**: ONE cycle (~10 minutes). Small working poller beats large plan.
-  - No daemon/background loop (just a sync function that polls once)
-  - No full story metadata fetching (topstories only gives IDs; construct minimal events)
-  - No retry/backoff logic (fail fast is fine for this proof)
-- **Error handling**: If fetch fails, return an error
-- **Payload structure**: Match what hn_monitor_integration.rs expects (see testdata/hn-monitor.flow.yaml pattern)
+The SMALLEST working implementation:
+
+- **Flow structure:**
+  ```yaml
+  spec_version: "1.0"
+  name: backlog-picker
+  steps:
+    - name: read-backlog
+      type: deterministic
+      command: "cat ops/BACKLOG.md"
+    - name: select-entry
+      type: deterministic
+      command: # deterministic selection logic (e.g., first non-done entry)
+    - name: emit-package
+      type: deterministic
+      command: # output structured work package JSON
+  ```
+
+- **Deterministic rule examples:**
+  - First entry in the file
+  - First entry matching a pattern
+  - Alphabetically sorted first
+  - Line-number based
+
+  Choose the simplest that is defensible as "deterministic"
+
+- **Output format:** Structured JSON work package with fields like:
+  - `title`: work package name
+  - `description`: what needs to be done
+  - `files_in_scope`: estimated file paths
+  - `gate`: which gate this serves
 
 ## Explicitly OUT of scope
 
-- Daemon/background polling infrastructure
-- Full HN story metadata (individual `/v0/item/{id}.json` fetches)
-- Retry/backoff for network failures
-- CLI commands to invoke the poller
-- Configuration files
-- Changes to hn-monitor flow spec or existing tests (beyond adding the poller test)
-- Any RFC or charter edits
-- Gates 1, 3-9
+- LLM or agent steps (gate 1 is deterministic-only for now)
+- GitHub integration (creating actual issues or PRs)
+- The full discover→implement→review→merge DAG
+- Issue labeling, assignment, or tracking
+- Integration with the existing drive.yaml workflow
+- Any changes to kernel code
+- Changes to gates 1, 2, or 4-9
+- ops/FORBIDDEN_PATHS violations (no kernel/relayflowd/src/engine/hn_poller.rs)
 
 ## Why this is the right work package
 
-Per ops/TARGET.md: "PR #15 landed testdata/hn-monitor.flow.yaml... but the triggering event comes from a test rather than Hacker News, so gate 2 is AMBER. Write the missing piece: a deterministic poller..."
+Per ops/TARGET.md: "Gate 3 per RFC-0001 is the Garden: flows that build and improve other flows. Do the SMALLEST honest first step, not the whole thing. Good candidate: a flow that reads ops/BACKLOG.md, picks one entry by a deterministic rule, and emits a structured work package."
 
-Gate 2's done-when (RFC-0001 §3): "a real proactive workload runs as a relayflow." The flow exists, the wake path works, but it's not monitoring anything real yet. The poller completes the circuit.
+This work package:
+- Stays strictly within gate 3 scope (SOFTWARE GARDEN foundation)
+- Is a CODE task as required
+- Does the smallest honest first step
+- Demonstrates "flows that build and improve other flows" (reading a backlog is the first step toward self-proposing work)
+- Has a clear, testable definition of done
+- Avoids all CONSTRAINTS from ops/TARGET.md (no server.rs, no hn-poller files)
