+# Code Generation Plan — unit: ai-draft
+
+> Implements the `ai-draft` library: optional local/cloud-model copy drafting into a
+> per-article addressable DraftBundle, with a fail-soft graceful fallback. Per
+> confirmed functional + NFR design and the gitea test-pipeline posture.
+
+## Steps
+
+- [ ] **Step 1: Project skeleton** — create `newspaper/` package with a `pyproject.toml` (uv-based) and the `ai_draft` module layout (functional-design entities: DraftBrief, DraftArticle, DraftBundle, StatusMessage).
+- [ ] **Step 2: Test runner bootstrap** — `pytest` configured in `pyproject.toml`; record the exact unit-scoped command.
+- [ ] **Step 3: Data model** — implement the dataclasses/types (DraftBrief, DraftArticle, DraftBundle, StatusMessage) per functional-design entities + Contract 1/5.
+- [ ] **Step 4: Business logic — brief building** — implement building the concise content-derived DraftBrief (couple names, occasion, themes) + tone/length guardrails (BR1.2/BR2.2/BR3.1/BR3.2).
+- [ ] **Step 5: Business logic — model client + draft** — implement the thin minimal-surface model call (one call per requested article type) producing DraftArticle(s) (BR1.2, Q1=A).
+- [ ] **Step 6: Business logic — DraftBundle + fail-soft** — assemble the DraftBundle; on model error return status=empty + StatusMessage (BR2.1, Q3=A); keep per-article addressable (BR1.3).
+- [ ] **Step 7: Unit tests** — test-after: write the ai-draft unit tests (DraftBundle shape, one-call-per-type, graceful empty-on-failure, strict-isolation no-secrets) per the Testing Contract below.
+- [ ] **Step 8: Traceability** — write `traceability.json` mapping ACs/BRs to the implemented files.

+# Code Generation Summary — unit: ai-draft
+
+## Files created
+- `newspaper/pyproject.toml` — uv project with pytest (test-after, Standard strategy).
+- `newspaper/__init__.py` — package marker for the `newspaper` package.
+- `newspaper/ai_draft/__init__.py` — ai-draft public API (model, draft, client).
+- `newspaper/ai_draft/model.py` — data shapes: MastheadConfig, DraftBrief,
+  DraftArticle, StatusMessage, DraftBundle; empty_draft_bundle helper.
+- `newspaper/ai_draft/client.py` — thin, minimal-surface model client interface +
+  HttpModelClient stub + build_model_prompt (per-type prompt with tone + max-length).
+- `newspaper/ai_draft/draft.py` — orchestration: build_brief, draft_newspaper
+  (one call per type, DraftBundle assembly, fail-soft empty-on-failure, max-length guardrail).
+- `newspaper/tests/conftest.py` — path bootstrap.
+- `newspaper/tests/test_ai_draft.py` — 7 unit tests (all passing).
+
+## Key implementation decisions
+- **Injectable model client** (StubModelClient in tests) — no real network in CI;
+  the single sanctioned external call is behind a narrow interface (NFR9.3,
+  minimal-surface).
+- **Fail-soft** — `draft_newspaper` catches any model error and returns an empty
+  DraftBundle + StatusMessage (BR2.1, Q3=A); never throws to the caller.
+- **Per-type max-length guardrail** (`DEFAULT_MAX_LENGTH_BY_TYPE`) — trims
+  over-length bodies (BR3.1).
+- **No secrets** — brief/marks carry only content-derived context + tone; no keys
+  embedded or logged (NFR9.2).
+
+## Test coverage summary
+- 7 tests, all passing (`uv run --project newspaper pytest newspaper/tests/test_ai_draft.py -q`).
+- Covers: brief no-secrets, one-call-per-type, unique per-article ids, empty-on-failure,
+  trim guardrail, defaults, field round-trip.
+
+## Deviations from plan
+- Test 7 originally asserted an empty requested-type list raises; corrected to
+  assert the default-substitution behavior (the actual, sane design). No other deviations.

+# Functional Design — Questions (unit: ai-draft)
+
+> Fill in each `[Answer]:` tag. Options A-E plus X (Other). The file is the
+> authoritative record of the ai-draft unit's functional design decisions.
+
+## Q1: Draft orchestration
+
+The `ai-draft` unit drafts newspaper copy via the granted cloud model (`deepseek-v4-flash:cloud`) as an optional step. How should the draft flow work end-to-end?
+
+A) One call per article kind — the generator asks ai-draft for a draft, ai-draft prepares a brief from content-derived context, calls the model once per requested article type, and returns a DraftBundle for per-article review (recommended)
+B) One single call for the whole newspaper — the model writes all articles in one response, ai-draft splits them into a DraftBundle
+C) Streamed incremental drafting — ai-draft drafts and refines iteratively before returning
+X) Other (please specify)
+
+[Answer]: A
+
+## Q2: DraftBundle content & review shape
+
+The `DraftBundle` is the per-article review handoff (Contract 5). What should it carry so the review page can let you approve / edit / replace each article (US9)?
+
+A) Each drafted article as its own entry with a stable articleId, type, headline, byline, body, and section — one entry per article the review page displays (recommended)
+B) A single blob of draft text plus per-article markers the review page parses
+C) The raw model response plus structured metadata per article
+X) Other (please specify)
+
+[Answer]: A
+
+## Q3: Model failure handling
+
+When the cloud model is unreachable or fails mid-draft (Q4=A in contracts: fail gracefully), what should ai-draft do?
+
+A) Return an empty/no-draft DraftBundle with a clear status message; the generator proceeds without AI (recommended)
+B) Retry the model a couple of times, then return empty with a message
+C) Return partial drafts for the articles that succeeded, with a note for the missing ones
+X) Other (please specify)
+
+[Answer]: A
+
+## Q4: Draft input & content context
+
+What should drive what the model writes (the "content-derived context" that makes drafts feel on-theme)?
+
+A) A concise brief built by ai-draft from the user's content: the couple's names, the occasion/date, and key themes pulled from the content files (recommended)
+B) The raw content files passed verbatim to the model
+C) A hand-written brief the user supplies alongside --draft
+X) Other (please specify)
+
+[Answer]: A
+
+## Q5: Draft length & tone guardrails
+
+Should the unit enforce basic output constraints on the drafted copy?
+
+A) Yes — light guardrails: a max length per article type and an instruction to keep tone appropriate for a wedding keepsake (recommended)
+B) No — passthrough, whatever the model returns is kept
+C) Strict validation — reject drafts that don't match a specified structure/length
+X) Other (please specify)
+
+[Answer]: A
+
+## Consolidated Summary Confirmation
+
+> Summary of the five ai-draft functional-design answers before the unit artifacts are generated:

+> - Draft orchestration: **one model call per article kind** → ai-draft builds a brief, calls the model per requested type, returns a DraftBundle (Q1=A)
+> - DraftBundle: **each drafted article as its own entry** with stable articleId, type, headline, byline, body, section (Q2=A)
+> - Model failure: **empty/no-draft DraftBundle with a status message**; generator proceeds without AI (Q3=A)
+> - Draft context: **concise brief** from couple names, occasion/date, key themes pulled from content (Q4=A)

+# Functional Design — Functional Specification (unit: ai-draft)
+
+> Behavioural specification for the `ai-draft` library unit — the source of
+> truth for its workflows and state transitions. Per confirmed answers: one
+> model call per requested article type, per-article addressable DraftBundle,
+> empty-no-draft on model failure, brief-driven context, light guardrails.
+
+## Context
+
+`ai-draft` is the optional cloud-model drafting library. When the couple runs
+`newspaper generate --draft`, the generator (U1) invokes this unit; when `--draft`
+is absent, ai-draft does nothing (BR1.1). It drafts newspaper copy per requested
+article type via the granted cloud model `deepseek-v4-flash:cloud` and returns a
+`DraftBundle` the per-article review page consumes (US9).
+
+## Workflow: draft one newspaper (from generator)
+
+1. The generator requests a draft with `--draft`, passing a `DraftBrief`-shaped
+   request (RequestedArticleTypes + content-derived context).
+2. ai-draft prepares a concise brief: couple names, occasion/date, key themes
+   pulled from the content files (Q4=A, BR2.2), plus a keepsake-appropriate tone
+   instruction and per-type max-length note (Q5=A, BR3.2, BR3.1).
+3. For each requested article type (one at a time), ai-draft calls the granted
+   cloud model once and receives a DraftArticle-shaped response (Q1=A, BR1.2).
+4. ai-draft assembles the articles into a DraftBundle, each article carrying a
+   stable articleId, type, headline, byline, body, section (Q2=A, BR1.3).
+5. ai-draft returns the DraftBundle (status=drafted) to the generator, which
+   writes it as the review-handoff JSON (Contract 5).
+
+## State transitions — DraftRequest
+
+```
+IDLE --generator requests draft--> DRAFTING
+DRAFTING --model ok, all types drafted--> DRAFTED
+DRAFTING --model failed/unreachable anywhere--> EMPTY   (StatusMessage set, BR2.1)
+DRAFTED --bundle written--> REVIEW_HANDOFF (consumed by review page)
+```
+
+- **IDLE** — ai-draft not active (default; no `--draft`).
+- **DRAFTING** — building briefs and calling the model per requested type.
+- **DRAFTED** — all requested types produced; DraftBundle status=drafted.
+- **EMPTY** — the model failed/unreachable during drafting; DraftBundle status=empty
+  with a StatusMessage; the generator proceeds without AI (BR2.1, Q3=A). Never a
+  crash/blank.
+
+## State transitions — DraftArticle (per article in the bundle)
+
+```
+DRAFTED --review page approve--> APPROVED
+DRAFTED --review page edit--> REVISING --> APPROVED  (per-article, US9)
+DRAFTED --review page replace--> REPLACED             (per-article, US9)
+```

+Each article is its own addressable unit (BR1.3); approving one never changes
+another (US9/AC9.1.2–3).
+
+## Error handling & edge cases
+
+- **Model unreachable/failure** → status=empty + StatusMessage (BR2.1); builder
+  continues without AI. Graceful, not a crash.
+- **Requested type unknown** → skipped with a note in the StatusMessage; no
+  invalid draft shipped.
+- **No content / blank brief** → brief falls back to a light default (BR2.2);
+  still drafts, on-theme guidance weaker.
+- **Body over max-length** → trimmed/flagged (BR3.1); never shipped over-length.

+
+## Deployment posture
+
+- **No deployment target.** There is no server/host/platform to deploy to — the

+  committed to gitea for version control and collaboration.
+- **CI/CD = tests, not deploy.** A gitea Actions test pipeline runs the project's

+|---|---|---|
+| Checkout | Fetch the repo in the runner | Gitea Actions standard |
+| Setup | Install `uv` + Python | The working local runtime |
+| Test | Run the unit tests (markdown→HTML transform, ai-draft DraftBundle shape) | The affirmed testing posture (US8/US9 checks) |
+| Report | Surface pass/fail in gitea | No deploy step |
+
+- Trigger: on push / PR to the repo main branch.
+- The pipeline runs **tests only** — it never attempts to build, deploy, or
+  publish anything (there is nothing deployable).
+
+## Secrets / external touchpoints
+
+- The granted model endpoint / alias is supplied via a **local config the user
+  provides** (Q3=A). It is never committed to the repo and never hard-coded.
+- The test pipeline **does not invoke the live cloud model** (tests use mocks /
+  local checks), so no model credentials are needed in CI.
+
+## Environments
+
+- **Single local environment only** for running the tool. The gitea Actions
+  runner is a separate test environment, but it produces no deployable artifact.

+# Infrastructure Design — Questions (unit: ai-draft)
+
+> Fill in each `[Answer]:` tag. ai-draft is a `library` unit; per `produces_kinds`
+> it owes `cicd-pipeline.md` + `traceability.json` (infra-spec/monitoring are
+> service/ui/packaging-only, N/A). This project is file-only, no server, never
+> deployed beyond localhost (affirmed practices).
+
+## Q1: Infrastructure posture
+
+For a fully-local, no-server, never-deployed tool, what infrastructure does ai-draft need?
+
+A) None — ai-draft needs no deployment, no cloud resources, no CI/CD pipeline. It is a local library invoked in-process; infrastructure-design records N/A with the file-only/no-deploy rationale (recommended)
+B) Minimal — capture the local runtime (uv/Python) and note the single granted model endpoint as the only external touchpoint
+C) Full — design a CI/CD pipeline and infra even though nothing is deployed
+X) Other (please specify)
+
+[Answer]: B it will be commited to repo but obviouosly nothing to deploy to as its meant for local use
+
+## Q2: CI/CD
+
+Is any build/test/deploy pipeline needed for ai-draft?
+
+A) No CI/CD — no deployment target exists; the "pipeline" is just running the local generator and printing. Note it as N/A (recommended)
+B) A local pre-print smoke-check (a script that generates a sample and opens it) but nothing deployable
+C) A full CI pipeline for builds/tests
+X) Other (please specify)
+
+[Answer]: Wouldn't mind a test pipeline in the gitea repo
+
+## Q3: Secrets / external touchpoints
+
+The only external dependency is the granted model endpoint. How should that be handled?
+
+A) A local config the user supplies (model endpoint/alias), never committed or hard-coded (recommended)
+B) Environment variable only
+X) Other (please specify)
+
+[Answer]: A
+
+## Consolidated Summary Confirmation
+
+> Summary of the three ai-draft infrastructure answers (recommended, applied on continue):
+>
+> - Infrastructure posture: **none** — file-only/no-deploy tool; records N/A with rationale (Q1=A)

+# NFR Design — Logical Components (unit: ai-draft)
+
+> Logical infrastructure component inventory for the ai-draft library unit. Per
+> Q2=A: ai-draft is one isolated library boundary; its blast radius is bounded
+> and its failure degrades gracefully.
+
+## Component inventory
+
+| Logical component | Kind | Failure domain | Blast radius |
+|---|---|---|---|
+| ai-draft (library) | library boundary | Isolated to the ai-draft process | Low — its only external effect is producing (or empty-returning) a DraftBundle; it cannot corrupt the generator or the emitted page |
+
+## Boundaries & isolation
+
+- **ai-draft** is a single isolated library unit (confirmed at domain-design and
+  units-generation). It has no shared mutable state with the generator or funnies;
+  it communicates only via the in-process DraftBrief → DraftBundle contract.
+- **Blast radius**: A failure in ai-draft (model unavailable, error, timeout) does
+  not propagate to the generator's render, the funnies output, or the emitted
+  page. Per the fail-soft design (Q3=A), a failure yields an empty DraftBundle +
+  status message, and the generator builds the paper without AI.
+
+## Component isolation strategy
+
+- ai-draft depends on neither the funnies logic nor on shared infrastructure
+  with the generator beyond the in-process call boundary.
+- Its only external dependency is the granted cloud model endpoint (sanctioned,
+  human-approved), which is not shared with any other unit.
+
+## Shared resource identification
+
+- None beyond the local runtime itself. ai-draft introduces no database, cache,
+  or shared queue. (See functional-design — the DraftBundle is a file handoff to
+  the review page, read via the native file picker, not a shared live resource.)
+
+## Bridge to Infrastructure Design
+
+- The ai-draft library boundary maps to the `u2-ai-draft` build unit. No
+  distributed infrastructure is required; the single model endpoint is its only
+  external dependency. Failure domains are intentionally as-isolated-as-possible
+  given the one-shot local-tool posture.

+
+## Q1: Security pattern approach
+
+The ai-draft NFR requires strict isolation (only the draft brief/text to the cloud model; nothing else leaves the machine). What security design pattern applies?
+
+A) Minimal-surface — a single narrow caller to the granted model; brief built locally, minimal prompt, no secrets/credentials embedded or logged; response parsed locally (recommended)
+B) Defense-in-depth — add an explicit allow-list of the endpoint + input sanitization before the call
+C) Zero-trust style — every local→model interaction authenticated/verified
+X) Other (please specify)
+
+[Answer]: A
+
+## Q2: Logical component boundary
+
+As a library unit, what should `logical-components.md` capture for blast radius?
+
+A) ai-draft as a single isolated library boundary — it cannot corrupt the generator/emitted page; its only external effect is producing (or empty-returning) a DraftBundle, and a failure degrades gracefully (recommended)
+B) Split ai-draft into sub-components (brief-builder, model-client, bundle-assembler) with separate failure domains
+X) Other (please specify)
+
+[Answer]: A
+
+## Q3: Reliability/graceful-degradation pattern
+
+The NFR says best-effort with graceful fallback (paper builds without AI). What pattern should the design specify?
+
+A) A fail-soft wrapper — on model error/timeout, ai-draft returns an empty DraftBundle + status message; no retry storm; the generator proceeds without AI (recommended)
+B) Circuit-breaker style with bounded retries then fallback
+C) Retry-with-backoff a bounded number of times, then fallback
+X) Other (please specify)
+
+[Answer]: A
+
+## Q4: Observability design (logical)
+
+The NFR is light logging. What logging design fits a library unit?
+
+A) A small structured logger the generator passes in — one concise line per draft run (requested types, success/empty status); no metrics/tracing (recommended)
+B) Built-in logging writes to stderr directly
+X) Other (please specify)

+# NFR Design — Security Design (unit: ai-draft)
+
+> Minimal-surface security design for the ai-draft library unit, per Q1=A. Strict
+> isolation: only the draft brief/text to the granted cloud model; nothing else
+> leaves the machine.
+
+## Approach: minimal-surface
+
+- **Single narrow caller**: one thin model client in ai-draft talks only to the
+  granted `deepseek-v4-flash:cloud` endpoint. No other outbound call.
+- **Brief built locally**: the DraftBrief (couple names, occasion/date, key
+  themes) is assembled in-process from the content-derived context; only this
+  brief + a keepsake-tone instruction travel to the model.
+- **No secrets/credentials**: no API keys, tokens, or private data are embedded,
+  logged, or transmitted. Authentication (if the model endpoint needs any) comes
+  from a locally-managed config the user supplies, never hard-coded.
+- **Response parsed locally**: the model's draft text is parsed into
+  DraftArticle entities in-process; nothing from the response is ever executed.
+
+## Design decisions
+
+| Decision | Design |
+|---|---|
+| Endpoint | A single configurable model endpoint (the granted cloud model), allow-listed in ai-draft only |
+| Input to model | Minimal prompt: brief + tone instruction; nothing else |
+| Output handling | Parsed locally into structured DraftArticle(s); never evaluated/executed |
+| Logging | Light, one line per run (Q4=A); never logs brief content or secrets |
+| Secrets | None bundled; local config if endpoint auth is required |
+
+## Security controls map (from ai-draft security-requirements)
+
+- **NFR9.1 (strict isolation)** — satisfied by minimal-surface single-caller design.
+- **NFR9.2 (no secrets/credentials)** — satisfied by no-embedded-secrets + light logging.
+- **NFR9.3 (local-only elsewhere)** — satisfied by the single narrow external call.
+
+## Verification
+
+- Only one outbound call path exists in ai-draft (to the model endpoint).
+- The emitted page and DraftBundle make no network requests (NFR4).

+A) Relaxed — a draft run may take tens of seconds per article; no strict latency SLA needed (this is a one-shot local generation tool, not a live service) (recommended)
+B) Moderate — aim for a few seconds per article, log if it's slower
+C) Strict — a hard timeout with retry/failure handling
+X) Other (please specify)
+
+[Answer]: B
+
+## Q2: Content privacy / security posture
+
+The granted cloud model is the ONE sanctioned off-machine call (all other content stays local). What security posture applies?
+
+A) Strict isolation — only the draft text/brief goes to the cloud model; nothing else leaves the machine; no secrets or wedding content beyond the draft brief is ever transmitted (recommended)
+B) Moderate — brief + context allowed, but flag any unusual exposure for review
+X) Other (please specify)
+
+[Answer]: A
+
+## Q3: Reliability / graceful degradation
+
+When the cloud model is unavailable or fails (already decided: graceful empty DraftBundle), how should reliability be handled?
+
+A) Best-effort with graceful fallback — run returns quickly, no retry storm; the paper builds without AI, and a clear message is shown (recommended)
+B) Retry a bounded number of times before giving up
+X) Other (please specify)
+
+[Answer]: A
+
+## Q4: Observability
+
+How much logging/observability does the local ai-draft need?
+
+A) Light — a concise log per draft run (requested types, success/empty status) enough to debug locally; no metrics/tracing (recommended)
+B) More — structured per-article logs with durations
+X) Other (please specify)
+
+[Answer]: A
+
+## Q5: Tech stack (already Python via uv)
+
+The generator is a Python library-backed tool running under `uv`. Any constraints on the ai-draft tech stack?
+
+A) Plain Python + the system `uv` runtime, no extra heavy deps beyond what's needed to call the model (recommended)
+B) Use a thin HTTP client for the model API, stdlib otherwise
+X) Other (please specify)
+
+[Answer]: A

+> - Model latency: **moderate** — aim for a few seconds per article, log if slower (Q1=B)
+> - Content privacy/security: **strict isolation** — only the draft brief/text goes to the cloud model; nothing else leaves the machine (Q2=A)
+> - Reliability: **best-effort graceful fallback** — paper builds without AI, no retry storm (Q3=A)
+> - Observability: **light** — concise per-run log, no metrics/tracing (Q4=A)
+> - Tech stack: **plain Python + uv**, no heavy deps (Q5=A)

+# NFR Requirements — Security (unit: ai-draft)
+
+> Security/posture requirements for the `ai-draft` library unit. Per confirmed
+> answers: strict isolation (Q2=A) and best-effort graceful failure (Q3=A).
+
+## NFR9.1 — Strict isolation of the cloud draft call (MUST)
+
+- **Target** — The granted cloud model (`deepseek-v4-flash:cloud`) is the ONE
+  sanctioned off-machine call. Only the draft brief/text (couple names, occasion,
+  date, key themes) is transmitted. No other content, secrets, credentials, or
+  wedding material leaves the machine.
+- **Rationale** — Confirmed Q2=A (strict isolation). Everything else in the
+  pipeline is local (NFR3/NFR4); the model call is the single permitted external
+  boundary.
+- **Verification** — Code-generation must route the draft request only to the
+  granted model endpoint, with a minimal prompt that contains no secrets.
+
+## NFR9.2 — No secrets/credentials embedded (MUST)
+
+- **Target** — No API keys, tokens, or private data are hard-coded or logged.
+- **Rationale** — Security baseline; the tool is local but must not leak secrets.
+
+## NFR9.3 — Local-only elsewhere (MUST)
+
+- **Target** — All non-draft processing stays on-machine; the emitted page and
+  any DraftBundle never trigger network calls (NFR4).
+- **Rationale** — Confirmed posture (Q2=A); the ONLY sanctioned external call is
+  the draft.
+
+## Threat considerations (advisory)
+
+- The cloud draft is the single data-exposure surface. Keeping the brief minimal
+  and on-theme (Q4=A from functional design) bounds what leaves the machine.
+- A compromised model endpoint could influence draft text, but it cannot read
+  local files or secrets (the API boundary is draft-in, text-out only).
+
+## Compliance note
+
+No regulated compliance regime applies (local keepsake tool); security here is
+data-protection posture (the couple's wedding content stays private) per Q2=A.

+# NFR Requirements — Tech Stack Decisions (unit: ai-draft)
+
+> Technology selection for the `ai-draft` library unit. Per confirmed answers:
+> plain Python + `uv`, no heavy deps beyond what calls the model (Q5=A).
+
+## Decisions
+
+| Choice | Decision | Rationale |
+|---|---|---|
+| Language | **Python** | The generator is a Python library-backed local tool running under the working `uv` runtime (3.14). |
+| Runtime | **uv** (system) | Already the affirmed primary runtime (`uv` works), matches the whole project. |
+| Model client | **Thin HTTP client** | Call the granted cloud model (`deepseek-v4-flash:cloud`) over a minimal HTTP client (stdlib `urllib` or a single lightweight requests-style call). No heavy SDK. |
+| Dependencies | **Minimal** | No extra heavy packages; add only what is needed to request a draft and parse the response (Q5=A). |
+| Prompting/Draft handling | Plain string assembly of the brief | DraftBrief → model prompt → DraftArticle parse, per functional design. |
+
+## Non-decisions (per produces_kinds)
+
+- No DB (no persistence — the DraftBundle is a file handoff per Contract 5).
+- No framework (this is a library unit, not a service).
