docs: re-author the three specs into docs/, plain style, anchors kept - #222
Merged
Conversation
invariants.md, data-model.md, and index-engine.md move from design/ to docs/ re-authored per the documentation style guide: short sentences, plain words, you-voice, no prose em dashes. Every invariant id and every section number the code cites (data-model §0-§10, index-engine §1-§8) keeps its meaning. index-engine §3/§4/§6 absorb the unique content of the indexing and retrieval HTML deep dives (incremental heuristic, stage-by-stage pipelines, verdict states, constants table, batching and the model swap). design/ itself is removed in a follow-up commit once every reference points here.

quickstart.md replaces quickstart.html and becomes the one home of the command reference and the environment-variable table. architecture.md replaces architecture.html as the orientation tour, linking into the specs instead of restating them. search-and-similarity.md replaces the HTML explainer: same plain-language walk, glossary, and component table, re-authored per the documentation style guide.

…the map The one guide to the harness (instruments, report blocks, exit gate, verdict record, process rules) now lives with the rest of the docs, its links re-pointed at the corpus files it governs. A short pointer README stays beside the corpus so anyone browsing evals/ still lands on the rules before editing. docs/README.md is the new docs home: one table naming the single home of each topic.

…repointed design/ is gone: the specs live in docs/ now, re-authored. The six HTML pages retire in favor of the Markdown guides that replaced them. Every reference follows: the root README's docs table and quick-start links, CLAUDE.md's truth table, ADR-0001/0013 and the ADR index, Cargo.toml and Makefile comments, fixtures/README, the desktop CLAUDE.md, ui/ source comments, and eval.rs's notebook-of-record pointers.

In `@docs/architecture.md`:
- Around line 27-30: Align the write-surface contract across both guides: in
docs/architecture.md lines 27-30, state that indexing does not edit notes while
explicit commands such as b2 mv, b2 write, and b2 add may edit files; in
docs/quickstart.md lines 139-147, remove the claim that body links are never
edited and document these explicit body-editing operations.
In `@docs/data-model.md`:
- Line 26: Change the “The two storage tiers” heading from level three to level
two so it directly nests under the top-level “Data model” heading and preserves
the document outline.
In `@docs/evals.md`:
- Around line 345-347: Update the documentation near the corpus-tag description
to state that current rows include the corpus field, while rows missing corpus
are legacy rows. Preserve the existing explanation of orthogonal/dense tagging
and their search_transfer behavior.
In `@docs/invariants.md`:
- Around line 155-158: Update invariant M3 in the documentation to scope the v1
embedding guarantee to notes, or explicitly identify resource embedding as a
future capability. Keep the existing single text-model behavior for shipped note
embeddings and avoid implying that resource extraction or embedding is currently
implemented.
- Around line 291-300: Update invariant C1 to qualify the reader guarantee:
state that readers are normally not refused and may wait for the bounded opener
budget, but a reader can be refused or report failure when that budget expires
due to a stuck writer. Preserve the existing guarantees that current complete
schemas require no write lock and partial schemas are never observed.
- Around line 58-70: Update docs/invariants.md lines 58-70 so W2 identifies move
repair as the only automatic or mechanical body rewrite while preserving
explicit Vault::write body saves. Update docs/data-model.md lines 364-369 to
replace “Exactly one of those touches the body” with wording that preserves the
distinction between automatic move repair and explicit editor saves, using the
same write contract.
- Around line 37-43: Align the pruning contract across docs/invariants.md lines
37-43 and docs/index-engine.md lines 161-168: if single-note operations
intentionally do not prune, scope S3’s full-rebuild equivalence and
incremental-equivalence statements to whole-vault reindexing, and state the same
limitation in both sections; otherwise remove the engine’s exemption so both
documents require pruning for every incremental operation.
- Around line 27-30: Update the S2 and S3 invariant definitions to explicitly
define logical equality: identical indexes exclude volatile indexed_at and mtime
values and internal chunks.id identifiers, matching the projection tests’
comparison behavior.
In `@docs/quickstart.md`:
- Around line 19-20: Update the B2 networking statement in the quickstart to
distinguish local operation after provisioning from setup-time and configured
remote services: document that b2 init downloads the embedding model, indexing
and query-time embedding then run locally, and chat endpoints may make network
calls when configured remotely.
In `@docs/search-and-similarity.md`:
- Around line 28-36: Update the embedding-dimension explanation near the BGE
model description to identify 768 as the BGE Base default, and state that the
configured embedding model determines the dimension; keep the surrounding
explanation of embeddings and vectors unchanged.

The write surface is stated the same way everywhere: indexing writes nothing, b2 add/write/mv change files only on command, and the move repair is the one body edit B2 composes itself (the editor save carries your own bytes). S2 defines logical index equality the way the projection tests assert it (indexed_at, mtime, and chunk row ids excluded); S3 scopes deletion pruning to the whole-vault pass, matching index-engine §8's wording. M3 scopes v1 embedding to notes, with the resource path marked designed-not-built. C1 names the bounded-budget report as the one refusal it permits. The quickstart says exactly when B2 uses the network (the one-time model download, and a remote chat endpoint only if configured). The explainer ties the 768 dimension to the default model, with bge-small's 384 beside it. evals.md notes rows older than the corpus key read as orthogonal. Two headings in data-model step h1 to h2 instead of h3. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01CnZh7mztkPnvXJ4GnfrZiE

Condition S2 on a fixed embedding space.
S2 includes vectors and centroids, but it says that the vault directory alone determines an identical index. M2 states that embed_model_id and the compute-device identity determine the embedding space. The same Markdown tree can therefore produce different vector rows after a model or device change.
State that projection equality requires the same meta.(embed_model_id, embed_dim) identity.
Proposed documentation fix
- Drop `b2.sqlite`, reindex, and you get an identical index back. Identical means *logically*
+ With the same embedding-space identity, drop `b2.sqlite`, reindex, and you get an identical
