# Citation Diversifier

> PRODUCES a citation-budget plan/report (`output/CITATION_BUDGET_REPORT.md`); does NOT edit the draft. Allocates an in-scope per-H3 budget (NO NEW FACTS) so drafts stop failing the global unique-citation gate; citation-injector applies it.

# Citation Diversifier (budget-as-constraints) [NO NEW FACTS]

## Triggers & routing

- **Trigger**: cite boost, citation budget, unique citations too low, add more citations, improve reference density, 引用太少, 增加引用, 引用密度.


Purpose: fix a common survey failure mode:
- the draft reads under-cited (or reuses the same few citations everywhere)
- the pipeline fails the **global unique-citation** gate

This skill does **not** change prose by itself.
It produces a constraint sheet: `output/CITATION_BUDGET_REPORT.md`.

## Inputs

- `output/DRAFT.md`
- `outline/outline.yml` (H3 ids/titles; used to allocate budgets per subsection)
- `outline/writer_context_packs.jsonl` (source of `allowed_bibkeys_{selected,mapped,chapter,global}` per H3)
- `citations/ref.bib`

## Output

- `output/CITATION_BUDGET_REPORT.md`

## Non-negotiables (NO NEW FACTS)

- Only propose citation keys that exist in `citations/ref.bib`.
- Only propose keys that are **in-scope** for the target H3 (prefer subsection-first scope; use chapter/global only when truly cross-cutting).
- Do not propose “padding citations” that would require adding new claims or new numbers.

## What a good budget report looks like (contract)

The report should feel like a *constraint sheet*, not a random list:
- It states the **blocking policy target** and the **gap-to-target** (how many unique keys are missing; policy default is `recommended`).
- For each H3, it proposes a scope-safe budget sized to actually close the gap:
  - small gaps: 3-6 keys / H3 is often enough
  - `course_paper`: cap suggestions at 3-6 keys / H3 and target the profile's 24/32 global budget
  - A150++ gaps: plan for ~6-12 keys / H3 (and avoid duplicates across H3 budgets)
- It gives placement guidance (where in the subsection those keys can be embedded without adding new facts).

Canonical (parseable) lines required (downstream validators depend on these):
- The target is derived from `queries.md:citation_target` (`recommended` by default for A150++).
- `- Global target (policy; blocking): >= <N> ...`
- `- Gap: <K>`  (gap-to-target; if `0`, injection can be a no-op PASS)

Optional (always reported; may be blocking depending on `citation_target`):
- `- Global recommended target: >= <N> ...`
- `- Gap to recommended: <K>`

Recommended prioritization (scope-safe):
- `allowed_bibkeys_selected` → `allowed_bibkeys_mapped` → `allowed_bibkeys_chapter`
- Use `allowed_bibkeys_global` only for:
  - benchmarks/protocol papers
  - widely-used datasets/suites
  - cross-cutting surveys/method papers referenced across chapters

## How this connects to writing (LLM-first)

After you generate the budget report:
- Apply it using `citation-injector` (LLM edits to `output/DRAFT.md`, NO NEW FACTS).
- Then run `draft-polisher` to remove any “budget dump voice” while keeping citation keys unchanged.

Important: `citation-injector` is **LLM-first**. Its script is validation-only.

## Workflow

1) Diagnose the global situation
- Read `output/DRAFT.md` and estimate the “unique-key gap” (or use `pipeline-auditor`’s FAIL reason).

2) Allocate budgets per H3 (scope-first)
- Use `outline/outline.yml` to enumerate H3s in paper order.
- For each H3, read its allowed key sets from `outline/writer_context_packs.jsonl`.
- Pick a small set of *unused* keys that strengthen positioning without requiring new claims.

3) Write `output/CITATION_BUDGET_REPORT.md`
Required structure:
- `- Status: PASS|FAIL`
- `- Global target (policy; blocking): >= <N> ...`
- `- Gap: <K>`
- `## Summary` (gap + strategy)
- `## Per-subsection budgets` (H3 id/title → suggested keys → placement hint)

## Script (optional; deterministic report generator)

If you want a deterministic first-pass budget report, run the helper script. Treat it as a baseline and refine the plan as needed.

### Quick Start

- `uv run python .codex/skills/citation-diversifier/scripts/run.py --help`
- `uv run python .codex/skills/citation-diversifier/scripts/run.py --workspace <workspace>`

### All Options

- `--workspace <dir>`
- `--unit-id <U###>` (optional)
- `--inputs <semicolon-separated>` (rare override; prefer defaults)
- `--outputs <semicolon-separated>` (rare override; default writes `output/CITATION_BUDGET_REPORT.md`)
- `--checkpoint <C#>` (optional)

### Examples

- Default IO:
  - `uv run python .codex/skills/citation-diversifier/scripts/run.py --workspace <workspace>`

## Done criteria

- `output/CITATION_BUDGET_REPORT.md` exists and has actionable, in-scope budgets.
- After applying the plan via `citation-injector`, `pipeline-auditor` no longer FAILs on global unique citations.
