# P5b implementation plan: questions on long documents
|
|
|
|
> **For the implementing model:** do not work from this file. The owner gives you one task file
|
|
> at a time. This file is the index for the owner and the reviewer.
|
|
|
|
**Goal:** P5a refuses `question` on a PDF longer than 200 digest chunks (~240k tokens) with
|
|
"use grep or pages". After P5b such a question is answered: at once from **BM25** over
|
|
page-aware chunks, while the document's chunks are **embedded in the background**; once they
|
|
are, later questions use today's hybrid score. Two facts found while planning:
|
|
|
|
- The embedding cache (`dcache` `GetEmbed`/`PutEmbed`, `EmbedKey`) exists but **nothing uses it**:
|
|
every question re-embeds every chunk.
|
|
- `Split` is line-based, so a chunk that starts mid-page carries no `--- page N ---` marker and
|
|
the model cannot cite its page.
|
|
|
|
| Task | Package | Given |
|
|
|---|---|---|
|
|
| 01-splitpages-bm25 | `internal/digest` (pure functions) | `digest/splitpages_test.go`, `digest/bm25_test.go` |
|
|
| 02-retrieval | `internal/digest` | `digest/retrieval_test.go` |
|
|
| 03-api | `internal/api`, `README.md`, `skill/SKILL.md` | `api/pdf_retrieval_test.go`; replaces `api/pdf_test.go` (P5a: the 200-chunk default becomes 5000) |
|
|
|
|
**How this plan was made:** acceptance tests first, no reference implementation; the given tests
|
|
compiled against a panic-only skeleton on master `1311cf3` and failed for the intended reasons.
