+# Code Generation Plan — unit: funnies
+
+> Implements the funnies library: derives theme words from content, builds an
+> AI-drafted 10x10 crossword + a find-a-word grid, selects/embeds an xkcd cartoon
+> via build-time content-enrichment, and returns a graceful fallback/empty
+> FunniesResult. Per confirmed functional + NFR + infra design.
+
+## Steps
+- [ ] **Step 1: Module skeleton** — `newspaper/funnies/` with `__init__.py`.
+- [ ] **Step 2: Test runner** — pytest configured (already in pyproject); record the unit command.
+- [ ] **Step 3: Data model** — Crossword, FindAWord, Cartoon, Comic, FunniesResult, FunniesBrief (functional-design entities, Contract 2/4).
+- [ ] **Step 4: Theme derivation** — derive theme words + context from content (BR1.1).
+- [ ] **Step 5: Find-a-word** — place theme words into a grid (BR1.3).
+- [ ] **Step 6: AI-drafted crossword** — injectable clue-drafter lays out a 10x10 grid (BR1.2).
+- [ ] **Step 7: Cartoon selection** — injectable xkcd/enrichment fetch, embedded locally, tasteful fallback (BR2.1/BR2.2, BR3.1).
+- [ ] **Step 8: FunniesResult + graceful empty/fallback** — status ready/fallback/empty + statusMessage (BR3.2, Q5=A).
+- [ ] **Step 9: Unit tests** — test-after (find-a-word, crossword layout, fallback, empty, self-contained).
+- [ ] **Step 10: Traceability** — write traceability.json + code-summary + source-manifest.

+# Code Generation Summary — unit: funnies
+
+## Files created
+- `newspaper/funnies/__init__.py` — public API.
+- `newspaper/funnies/model.py` — FunniesBrief, Crossword, FindAWord, Cartoon,
+  Comic, FunniesResult (+ is_self_contained BR4.1/NFR4 check).
+- `newspaper/funnies/find_a_word.py` — theme derivation (BR1.1) + deterministic
+  find-a-word grid construction (BR1.3).
+- `newspaper/funnies/crossword.py` — 10×10 crossword with injectable AI
+  clue-drafter (BR1.2, Q1=B/Q2=B).
+- `newspaper/funnies/cartoon.py` — xkcd/enrichment fetch + tasteful content-derived
+  fallback (BR2.1/BR2.2), comic build (BR3.1).
+- `newspaper/funnies/builder.py` — FunniesBuilder orchestrator, graceful
+  ready/fallback/empty (BR3.2, Q5=A).
+- `newspaper/tests/test_funnies.py` — 7 unit tests, all passing.
+
+## Key implementation decisions
+- **Injectable clue-drafter + cartoon source** — no real network in CI; the
+  sanctioned content-enrichment fetch is behind narrow interfaces.
+- **Deterministic grid layou**t — find-a-word uses longest-first systematic
+  placement with a fixed seed; crossword lays out on a 10×10 grid.
+- **Graceful empty/fallback** — no viable content returns an empty FunniesResult
+  + statusMessage (BR3.2, Q5=A); cartoon-not-found falls back to a tasteful
+  generated strip, never a remote URL at print (BR2.2).
+- **Self-contained** — all art_refs are local/bundled (never http(s)), BR4.1/NFR4.
+
+## Test coverage summary
+- 7 tests passing: theme derivation, find-a-word placement, 10×10 crossword +
+  clues, cartoon success (local embed), cartoon failure fallback, empty-no-content,
+  self-contained output.
+
+## Deviations from plan
+- Find-a-word grid is 12×12 (not fixed by plan) and may omit theme words on very
+  dense inputs by capacity — an inherent fixed-grid limit, not a defect; the
+  realistic bounded set fits deterministically. No other deviations.

+# Unit Test Instructions — unit: funnies
+
+## Test framework / config
+- pytest, under `newspaper/tests/`.
+
+## How to run THIS UNIT's tests (exact command)
+```bash
+uv run --project newspaper pytest newspaper/tests/test_funnies.py -q
+```
+
+## Strategy / coverage (Standard)
+- 5-8 unit tests: theme word derivation, find-a-word placement, crossword grid layout, cartoon fallback, empty FunniesResult, self-contained output.
+
+## Mocking
+- Mock the clue-drafter (cloud model) and the cartoon/enrichment fetch — no real network in CI.
+
+## Test cases
+1. theme words derived from content
+2. find-a-word places every word
+3. crossword builds a 10x10 grid + clues
+4. cartoon fetch success → embedded local ref
+5. cartoon fetch fails → tasteful fallback strip (not a remote URL)
+6. empty FunniesResult on no viable content + statusMessage
+7. funnies output is self-contained (no remote URL at print)
