What this PR adds

tools/affine-cli is a headless Rust CLI for the local-first AFFiNE store. Agents and scripts can create and edit AFFiNE content in the local nbstore while the app is closed. Every command emits JSON. Discussed in #15361.

Command surface

Area Commands
Workspace workspace create, workspace list (a corrupt DB gives a per-entry error, not a full failure)
Docs doc create/list/read/update/set-title/set-mode/delete, doc add-latex
Markdown full round-trip, with $…$ / $$…$$ math and affine:latex blocks
Blobs blob put/get/list (SHA-256 content keys, the app convention)
Search search on the nbstore BM25 indexer (a CLI-private cli:doc index)
Diagrams diagram add-shape/add-text/add-connector, diagram create --spec (atomic), diagram repair-labels

Safety guards

  • Write lock: commands that write refuse with "error":"locked" while another process holds the workspace DB open. The check is an F_GETLK probe of the SQLite WAL lock. search also takes the lock because it writes index rows. The global --force flag overrides the lock.
  • The CLI rejects reserved doc ids: db$…, userdata$…, and the root doc (its id equals the workspace id).
  • The CLI validates geometry before it writes. One malformed xywh string breaks the full edgeless surface in the app.
  • diagram create is atomic. The CLI validates the full spec first, then writes one delta or nothing.

Real-yjs decode check (new workflow)

The y-octo reader normalizes some encodings that real yjs decodes differently. A bare top-level Any::Array decodes to its last element in the browser. This caused a real bug: connector labelXYWH broke rendering and selection (see docs/affine-cli-edgeless-render-postmortem.md). The new affine-cli-yjs-compat workflow emits fixtures with the CLI's own writers. It then decodes the fixtures in Node with the app-pinned yjs (13.6.21) and asserts every field. No pure-Rust test can cover this seam.

Vendored doc parser

src/doc_parser is the former affine_common::doc_parser, which PR #15197 removed in favor of the published affine_doc_loader crate. The CLI needs three things that affine_doc_loader 0.1.3 does not have:

  1. latex/math markdown parsing and affine:latex read-back
  2. a fix for standalone $$…$$ blocks that dropped the text after them in the same paragraph
  3. escapes for literal $ on render, so that prose does not re-parse as math

I am happy to move these three changes into affine_doc_loader and delete the vendored copy. See #15361.

Blast radius

The PR touches only tools/, the root workspace members list, Cargo.lock, docs/, and one new workflow file. It does not modify an existing crate or package.

Verification

  • 129 lib tests (this includes the vendored parser round-trip suite) and 4 e2e suites, all green
  • cargo clippy --all-targets -- -D warnings is clean, cargo fmt --check is clean
  • The real-yjs chain passes locally: emit_yjs_fixtures, then yjs-compat/check.mjs
  • I verified diagram output against the desktop app (v0.26.3) over CDP. Selection, the connector tool, and rendering all work.

Summary by CodeRabbit

  • New Features

    • Added a command-line interface for managing workspaces, documents, diagrams, search, blobs, and LaTeX content.
    • Added Markdown import/export with support for tables, media, embeds, lists, and math.
    • Added diagram creation and editing with shapes, text, connectors, layouts, and label repair.
    • Added structured JSON output, locking safeguards, validation, and resilient error handling.
  • Bug Fixes

    • Fixed connector label compatibility issues that could corrupt diagrams and cause stale canvas pixels.
  • Documentation

    • Added CLI guides, command references, design documentation, and a rendering postmortem.
  • Tests

    • Added end-to-end coverage for CLI workflows and compatibility with Yjs.

A Rust CLI (tools/affine-cli) that lets agents and scripts create and edit
AFFiNE content in the local nbstore without the app running: workspace/doc
CRUD, markdown round-trip (incl. $...$ / $$...$$ math), blobs, BM25 search,
and edgeless diagrams (shapes, connectors, labels, spec-driven layout).

Highlights:
- Vendors the doc parser as src/doc_parser (formerly affine_common::doc_parser,
  removed upstream in toeverything#15197 in favour of the published affine_doc_loader
  crate). The vendored copy adds the latex/math markdown port plus round-trip
  fixes (trailing text after standalone $$...$$, literal-dollar escaping) -
  offered upstream for affine_doc_loader adoption.
- Real-yjs decode check in CI: fixtures emitted by the CLI's own writers are
  decoded with the app-pinned yjs (13.6.21) and shape-asserted - the
  cross-library seam y-octo's own reader cannot test (labelXYWH postmortem,
  docs/affine-cli-edgeless-render-postmortem.md).
- Runtime guards: open-workspace write lock (F_GETLK probe, --force override;
  also covers search's index writes), reserved doc ids, xywh validation,
  atomic --replace diagram create.
- Ships an agent skill (skills/affine) documenting every command and the JSON
  output contract.

Touches only tools/, the workspace members list, Cargo.lock, docs/, and one
new workflow file. Verified: 129 lib tests + e2e suites green, clippy
-D warnings clean, fmt clean, real-yjs compat check passes.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟡 Moderate · up to 57e05

Concurrent writes can corrupt workspace updates on non-Unix systems, malformed documents can exhaust memory, and workspace identifiers may escape the configured storage root. These issues should be resolved before merge.

The !== undefined sweep can't catch the documented bug class.

The header says an array field decoding to a scalar is the bug class, but the collapsed labelXYWH decoded to a number — defined, so v !== undefined passes. Only the explicit arrayFields loop actually guards it. Either reword the comment so the sweep reads as a presence smoke-test, or strengthen it (e.g. flag values that are numbers where a [x,y,w,h]-style key is expected) so a future array field added without being listed in arrayFields isn't silently unchecked.

Pre-flight load doesn't guard the empty/sentinel binary.

Every other entry point routes through is_empty_doc_bin before apply_update_from_binary_v1; here an empty or [0,0] bin goes straight into the apply and would surface as a corruption error rather than the intended "no surface → skip". Cheap to align:

-        let mut doc: Doc = DocOptions::new().build();
-        doc.apply_update_from_binary_v1(doc_bin)?;
+        if is_empty_doc_bin(doc_bin) {

Use dirs::config_dir() on Linux so CLI paths match the Electron app layout.

AFFiNE data on Linux is stored under ~/.config/AFFiNE, but dirs::data_dir() falls back to ~/.local/share/AFFiNE on XDG-compliant systems. This makes default CLI commands target the wrong workspace path. Add an OS-specific fallback for Linux, and broaden the doc comment beyond macOS.

- Around line 899-929: Avoid validating shape and connection modes twice: update
the preflight validation around node_index and the later
ShapeParams/DiagramEdgeParams construction to parse and retain the resolved
shape and edge mode values, including the rect and elbow defaults, then reuse
those stored values instead of calling shape_type and conn_mode again.

In `@tools/affine-cli/src/doc_parser/blocksuite.rs`:
- Around line 92-98: Update find_block_id_by_flavour to resolve duplicate
flavour matches deterministically instead of returning the first HashMap
iteration result. Collect or compare matching IDs and return a stable choice,
such as the smallest ID, while preserving None when no block matches.

In `@tools/affine-cli/src/doc_parser/markdown/delta.rs`:
- Around line 96-101: Add a regression roundtrip test alongside the existing
dollar-escaping tests, covering a literal “$” at the end of one formatting run
immediately followed by a differently styled run such as italic or bold. Verify
parsing and serialization preserve the formatting boundary and dollar character,
using the existing test helpers and conventions.

In `@tools/affine-cli/src/doc_parser/markdown/parser.rs`:
- Around line 105-151: The attrs and attrs_with methods duplicate
InlineStyle-to-TextAttributes conversion logic. Add a shared apply helper for
InlineAttr and mutable TextAttributes, move the Link, Color, and default
handling there, then have both attrs and attrs_with call it while preserving
their existing stack and extra-attribute behavior.

In `@tools/affine-cli/src/doc_parser/read/mod.rs`:
- Around line 303-309: Update the PAGE_FLAVOUR handling in the document parser
so missing or empty prop:title values preserve the existing DEFAULT_PAGE_TITLE
instead of overwriting doc_title with an empty string. Keep non-empty page
titles unchanged and align this behavior with parse_doc_from_binary.
- Around line 702-714: The table_cell_texts function currently emits cell text
in arbitrary map-key iteration order. Update it to derive and apply stable
row/column ordering, preferably by sorting the matching
prop:cells.<row>.<col>.text keys before collecting values, while preserving the
existing filtering and empty-value behavior.
- Around line 64-73: Align text length accounting across text_content,
text_content_for_summary, and push_text by using one consistent unit for the
summary budget. Update push_text to append only the portion that fits within
remaining, rather than appending the entire block before decrementing. Preserve
the hard max_summary_length cap for both direct and fallback text paths,
including boundary and exhausted-budget cases.

In `@tools/affine-cli/src/doc_parser/value.rs`:
- Around line 46-82: Update value_to_any to track recursion depth while
traversing nested arrays and maps, and return the established ParseError when
the depth exceeds a sane limit instead of recursing indefinitely. Propagate the
depth through all recursive calls and preserve existing scalar, array, and map
conversions within the limit.

In `@tools/affine-cli/src/doc_parser/write/builder.rs`:
- Around line 469-475: Consolidate the duplicate boxed_empty_map and
note_background_map helpers into a single shared helper, and update their
callers to use it; alternatively, make each helper construct its intended
distinct map shape so the names are meaningful. Preserve the existing ParseError
conversion behavior.

In `@tools/affine-cli/src/doc_parser/write/update.rs`:
- Around line 136-163: Update sync_nodes to accept target as &[BlockNode]
instead of &mut [BlockNode], then pass &new_node.children directly to recursive
sync_nodes calls in the Keep and Update branches. Remove the per-node children
clones while preserving the existing synchronization behavior.

In `@tools/affine-cli/src/engine.rs`:
- Around line 707-715: Extract the duplicated find-surface and value-removal
sequence into a shared clear_elements function accepting &Doc and returning
Result<(), CliError>. Replace the inline loop in create_diagram’s replace branch
and the equivalent logic in clear_surface_elements with this helper, preserving
their existing error propagation and behavior.

In `@tools/affine-cli/src/error.rs`:
- Around line 67-73: Consolidate the separate `impl CliError` blocks in error.rs
into one implementation, preserving the explicit `From<y_octo::JwstCodecError>`
conversion to `CliError::Crdt(e.to_string())`. Reword its comment to explain
that, although JwstCodecError is a thiserror enum, the manual conversion
intentionally flattens CRDT errors and should not be replaced with `#[from]`.

In `@tools/affine-cli/src/store.rs`:
- Around line 135-214: Refactor LocalBackend initialization so open resolves
self.pool.get(self.universal_id.clone()) once and stores the resulting storage
handle when its lifetime permits. Update all DocBackend methods, including
set_space_id, push_update, get_doc_snapshot, get_doc_updates, delete_doc,
set_blob, get_blob, list_blobs, crawl_doc_data, index_doc, flush_index, and
search, to reuse that stored handle instead of resolving the pool on every call.

In `@tools/affine-cli/tests/commands_e2e.rs`:
- Around line 114-130: Simplify the explanatory comment in read_primary_mode to
one concise sentence stating that the db$docProperties document is reconstructed
by re-merging raw update blobs from the updates table. Remove the
abandoned-approach narration and any statements that contradict the following
read_doc_update_blobs call.

In `@tools/affine-cli/tests/diagram_e2e.rs`:
- Around line 12-97: Move the duplicated test helpers TempBase, run_raw, run_ok,
run_err, create_ws, create_doc, and any_str from the e2e test files into a
shared tests/common/mod.rs module. Import and reuse those helpers in
diagram_e2e.rs and commands_e2e.rs, preserving the existing nanoid flag
workaround and JSON parsing behavior.

I pushed 1b95e0e to address all findings from the automated review.

  • Workflow token surface: fixed. The job now sets permissions: contents: read and checks out with persist-credentials: false.
  • Cycle protection in parent-chain walks: fixed. get_list_depth, nearest_by_flavour, has_skipped_markdown_ancestor, and block_level now carry a visited set. A regression test builds a cyclic parent chain and asserts termination.
  • escape_math_dollars op-boundary under-escape: fixed. The escape decision now sees the first character that the next op renders, or the close marker of the current style. A styled neighbor reports a marker char, which can only over-escape (a \$ still round-trips as a literal $), never under-escape. A new unit test covers a trailing $ before a bold run.
  • Table id regeneration: fixed. apply_table_block_props now reuses row and column ids by position, mints ids only for added rows and columns, removes stale keys, and writes only values that changed. A regression test asserts that a one-cell edit keeps every row and column id.
  • Silent if let on the page-stub read-back: fixed. All three sites now propagate an error instead of leaving an id-less entry in meta.pages.
  • Duplicated page-stub insert: fixed. add_doc_to_root_doc and update_root_doc_meta_title now call the shared insert_page_stub.
  • Malformed fraction digits panic: fixed. validate_order_key rejects non-base-62 fraction digits, and the midpoint digit lookups plus the b_chars[i] index are now fallible or bounded. A new test covers keys like a0$.
  • open creates the DB for read paths: fixed. The new LocalBackend::open_existing errors when the database file is absent, and every command except workspace create uses it. An e2e test asserts that a wrong --workspace id does not create a workspace.

The local gate is green: 133 lib tests plus the e2e suites, cargo clippy --all-targets -- -D warnings, cargo fmt --check, and the real-yjs (13.6.21) decode chain.

144-169: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Include cell keys in the comparison to cover the full id contract.

The filter keeps only prop:rows. and prop:columns. keys. A cell key embeds both the row id and the column id, so it is the key shape that breaks first when ids are reminted. Add prop:cells. to the filter, and compare the key list after the edit. The edited cell changes its value, not its key, so the key list stays stable.

                 let mut keys: Vec<String> = block
                     .keys()

First of all — thank you for this PR. This is one of the highest-quality external contributions we've received: the storage layer reuses our own code instead of reimagining it, the e2e tests drive the real binary against a real store, the docs are honest about their own limitations, and the yjs-compat harness shows you understood exactly where the risk in this design lives. We did a deep review of the full branch; here is what we found, the good and the bad, and where we'd like to take it from here.

Why this is moving to draft

  1. The maintainer position from #15361 stands: @darkskygit won't move forward with CLI/MCP editing until the y-octo ↔ yjs behavioral differences are resolved, since they can make merging of edit operations inaccurate. That work is in progress on our side.
  2. The branch head currently doesn't compile. Canary bumped y-octo 0.0.3 → 0.1.0 in #15363 (Any::Object is now boxed), and the merge commit dae0c0ea58 pulled that in without a rebuild — cargo check -p affine-cli fails with 7 lib + 3 test errors (e.g. doc_parser/markdown/delta.rs:189, doc_parser/value.rs:78, write/root_doc.rs:30, engine.rs:307/395/618). CI hasn't surfaced this because the workflow runs were still pending approval for a first-time contributor.

What's verified good

We checked the PR's claims against the app code rather than taking them on faith. These hold up:

  • Storage goes through affine_nbstore itself (use-as-lib), not a reimplementation: push_update/delete_doc/timestamp collision-retry are the app's own logic, snapshots is never written directly, and the path layout + universal-id format (trailing semicolon included) match the electron helper exactly.
  • The F_GETLK probe targets the right byte (SQLite's WAL dead-man-switch at offset 128 of -shm), the unsafe block is minimal and sound, and the private cli:doc FTS index instead of touching doc:title is the right call.
  • fractional_index.rs is a faithful port of fractional-indexing@3.2.0, and you correctly identified that surface elements use the raw generateKeyBetween (via LayerManager.generateIndex()), not the jittered V2 wrapper used elsewhere.
  • The e2e suites are real round-trips: decoding stored SQLite bytes with y-octo and re-reading through the production reader, plus a lock test that holds a live WAL connection. The locked-DB + --force behavior is genuinely exercised.
  • The workflow security posture (pull_request trigger, contents: read, persist-credentials: false) is above our current repo baseline.

Confirmed defects

Each of these was reproduced against the branch (we wrote throwaway tests where needed), not just eyeballed:

  1. escape_math_dollars under-escapes $ before digits → silent content corruption. doc_parser/markdown/delta.rs (~L340) assumes $+digit can't open math, but pulldown-cmark 0.13 disagrees: a $10-$20 range exports unescaped, and re-ingest turns it into an inline equation (latex="10-"). Insidiously, the markdown string round-trips byte-identical while the doc content changes, which is why the existing currency test (whitespace-blocked closers) passes. Fix: drop the is_ascii_digit exemption — escape any $ followed by non-whitespace. Note the earlier op-boundary fix from the CodeRabbit round is itself correct; this is a different hole.
  2. Table updates wipe app-authored row/column props. The stale-key sweep in write/builder.rs:317-341 whitelists only .rowId/.columnId/.order/.text, so prop:columns.<id>.width and .backgroundColor set by the app get deleted from rows/columns that were retained. The sweep should key on retained id segments, not exact-key membership. (The id-reuse part of your fix is otherwise correct and its test passes.)
  3. Slice panic on a hostile table key. write/builder.rs:374 computes key[prefix.len()..key.len()-suffix.len()]; the key "prop:rows.order" (prefix+suffix, no id segment) makes that range 10..9 and panics. Same corrupt-doc class the PR hardens elsewhere — guard with strip_prefix/strip_suffix.
  4. One recursion is still unguarded. The four visited-set guards you added are real and tested, but write/update.rs:112-134 (build_stored_tree) recurses over sys:children with no visited set — a corrupt doc with a child cycle overflows the stack (abort, not Err) in doc update.
  5. next_index breaks on grouped elements. engine.rs:471-482 takes the string-max of existing index values and passes it raw to generate_key_between. Compound indexes like a1-a0V (any doc where the user ever grouped canvas elements) win the string-max, then validate_order_key rejects '-' — every diagram add-* fails on such docs. The app strips group suffixes first (ungroupIndex, blocksuite/framework/std/src/utils/layer.ts); a one-line truncate-at-'-' fixes it.

Where the docs/claims oversell the implementation

  • "diagram create is atomic … one delta or nothing" is only true for the surface. Every diagram command performs a second, separate write (ensure_edgelessdb$docProperties, commands.rs:649-654, after the element push at e.g. :678-679). If the second write fails, the CLI returns ok:false/exit 1 but the element is already persisted — a caller treating non-zero exit as "nothing happened" is wrong.
  • "Every command emits JSON" fails for the whole clap error class. Cli::parse() (main.rs:14) runs before the JSON envelope: missing required flags, conflicting flags, unknown subcommands print plain text to stderr and exit 2 with empty stdout — exactly what SKILL.md tells agents to parse as JSON.
  • The "write lock" is a one-shot pre-flight probe, not a lock. There's a real TOCTOU window between the probe and the write (SQLite integrity is never at risk, but the description promises more than the mechanism delivers). And on Windows the probe unconditionally returns false (store.rs:146-149) — the documented error:locked contract silently doesn't exist there.
  • Every command — including doc read — silently runs sqlx migrations on the user's DB (store.rs:87-88 → nbstore migrate()). A CLI built from a newer canary than the installed app upgrades _sqlx_migrations in place and the older app can then fail to open its own database. This needs a check-and-refuse instead of an implicit migrate.
  • Minor: connector endpoints are never checked for existence (disclosed in REFERENCE.md, but trivially guardable since the surface map is already loaded); diagram create --spec has no node/edge cap and separate() is O(n²·200) with silent non-convergence; every parser invocation mints a fresh y-octo client id, which will permanently bloat state vectors under agent-driven usage.

The structural concerns (why we can't merge even after the fixes)

  1. The yjs-compat harness doesn't cover the risk that gates this PR. It asserts full-state updates applied to fresh Y.Docs — but what the app decodes row-by-row from the DB are raw deltas, and the deletion-bearing paths (doc update structural diff, --replace, remove_doc_from_root) produce deltas carrying delete sets. Not one deletion is ever decoded by real yjs in CI, and delete-set/skip encoding is precisely the historic y-octo↔yjs divergence area. Merge semantics against concurrent app edits (the exact blocker from #15361) are untested and untestable in this harness shape. The harness idea itself is genuinely valuable — see the path forward below.
  2. The drift surface is large and invisible. The CLI hardcodes ~14 categories of app conventions: 31 block flavour strings, sys:*/prop:* keys, schema version integers (page v2, surface v5), the $blocksuite:internal:native$ marker, the xywh wire format, root-doc meta shape, blob SHA-256 keys, etc. The compat workflow only triggers on tools/affine-cli/** — a BlockSuite schema change would never run it. Merging means every future schema migration acquires a second consumer with no compile-time or CI-time link.
  3. The vendored doc_parser is a 9.2k-line fork of code we deliberately removed in #15197. (Also: the semantic delta vs the pre-removal code is six changes, not three — the cycle guards, table id reuse, and page-stub hardening from your review-fix round are in there too. Worth knowing for extraction.)

Path forward

  • Please split the latex/math parser work into a PR against affine_doc_loader once @darkskygit publishes its repo (as discussed in #15361). Our analysis says it extracts cleanly: the math support + $$…$$ trailing-text fix are naturally one commit, the $-escaping a second, and the table/cycle/page-stub fixes a separate PR — but the digit-escape fix (defect 1) must ship with it, or the feature lands upstream carrying the same corruption bug. Note the extraction can't be produced by diffing files (the vendored copy was reformatted 2→4-space); regenerate function-scoped hunks against upstream formatting.
  • We'd love to fold the real-yjs fixture harness into the y-octo interop testing effort — extended to decode raw per-row deltas and delete-set-heavy sequences, it becomes exactly the guard that work needs. Your offer to contribute it there is very welcome.
  • The CLI itself stays on hold until the y-octo/yjs interop work lands; at that point we'll decide the CLI-vs-MCP surface question together rather than running two parallel tracks.

Keeping this open as a draft so the discussion and the harness work have a home. Thanks again — the postmortem alone (docs/affine-cli-edgeless-render-postmortem.md) is the kind of contribution that makes a codebase healthier, and we'd genuinely like to keep working with you on the pieces above.

Canary bumped y-octo 0.0.3 -> 0.1.0 in toeverything#15363, which boxes Any::Object.
Wrap the ten construction sites and deref the two consumption sites.
No behaviour change; 133 lib tests and the e2e suites pass.
- escape_math_dollars exempted `$` before a digit as currency, but
  pulldown-cmark reads `$10-$20` as the inline equation `10-`, so
  `a $10-$20 range` exported unescaped and re-ingested as math. Every
  `$` followed by non-whitespace now escapes; the parser reads `\$`
  back as a literal `$`.
- build_stored_tree recursed over sys:children with no visited set, so
  a corrupt doc with a child cycle overflowed the stack. It now carries
  a path-visited set like the four parent-chain walks and returns a
  `cyclic sys:children at block` error.
The merge of canary left the lock stale for affine-cli's nanoid 0.4
dependency, so --locked builds failed.
…ed keys

The stale-key sweep in apply_table_block_props whitelisted only the keys
the CLI writes itself (.rowId/.columnId/.order/.text), so a one-cell edit
deleted app-authored props such as prop:columns.<id>.width and
prop:rows.<id>.backgroundColor on rows/columns that were retained. The
sweep now keys on the id segment of prop:rows.<id>.*, prop:columns.<id>.*
and prop:cells.<rowId>:<columnId>.* and only removes keys whose row or
column id was dropped.

existing_table_ids extracted the id with index arithmetic, which panicked
on a hostile prop:rows.order key (prefix + suffix, no id). It now uses
strip_prefix/strip_suffix and skips an empty id.

The table id stability test also compares prop:cells. keys so the full
<rowId>:<columnId> contract is covered.
- next_index strips group suffixes (ungroupIndex parity) so diagram add-*
  works on docs with grouped canvas elements
- connector endpoints must exist on the surface; new structured
  unknown_element error instead of a dangling connector
- diagram create --spec capped at 500 nodes / 2000 edges; layout
  separate() reports non-convergence instead of returning silently
- rewrap_connector_labels pre-flight honours is_empty_doc_bin
- doc comments cite the pinned yjs 13.6.21
Outstanding CodeRabbit items:
- agent-cli-design.md: historical-status header, generic repo reference
  instead of a personal path, annotate stale "no latex" / "no code" notes,
  remove the stray code fence.
- REFERENCE.md: document `diagram repair-labels` (syntax, JSON output,
  locking, idempotence) and list `orthogonal` as an alias of `elbow`;
  cli.rs help and the conn_mode error message list it too.
- skills/README.md: pin `skills@1.5.23` and use a commit-SHA source path.

Round-1 minors (non-engine.rs):
- entity-escape <img> captions and database option spans, decode on read
- escape `|` in rendered table cells; size code fences to the content
- enforce MAX_MARKDOWN_CHARS as a char count
- base_dir uses dirs::config_dir() so Linux matches Electron's appData
- cli.rs module doc and yjs-compat/check.mjs comment made accurate
- diagram e2e asserts primaryMode == edgeless
Addresses the four "docs oversell the implementation" findings from the
maintainer review of affine-cli.

- Usage errors emit the JSON envelope: main uses Cli::try_parse() and prints
  {"ok":false,"error":"usage",...} on stdout with exit code 2 for unknown
  subcommands and missing/conflicting flags. --help/--version keep plain text.
- Diagram commands write the edgeless mode flag before the element delta, so a
  failed element push leaves at most a harmless flag instead of a persisted
  element behind ok:false. Docs no longer call the whole command atomic.
- The "write lock" is documented as a one-shot pre-flight open-app check with
  a TOCTOU window; db_in_use_elsewhere returns InUseProbe, and the Windows
  path (not implemented) now surfaces a "warnings" entry in the JSON output.
- The CLI no longer migrates an existing workspace DB implicitly: open_existing
  reads _sqlx_migrations read-only and compares with affine_schema's migrator,
  refusing behind-schema DBs (error:migration_required, opt in with the new
  --allow-migrate flag) and newer-than-CLI DBs (error:db_newer). workspace
  create still migrates a fresh file.

New e2e tests cover usage errors, help/version passthrough, and the current,
behind, and newer schema cases. CHANGELOG, SKILL.md, REFERENCE.md and
docs/agent-cli-design.md updated.
The compat harness only applied merged full states to fresh Y.Docs, so no
deletion the CLI writes was ever decoded by real yjs. The app reads raw
per-row deltas out of the workspace database, and every deletion-bearing
path (`doc update` structural diff, `diagram create --replace`,
`remove_doc_from_root`, table row removal) pushes a delta carrying a
delete set.

- emit_yjs_fixtures now records the exact bytes of each row the CLI pushes
  through nbstore push_update, under seq/<name>/<i>.bin, with y-octo's
  projection of the doc and the CLI reader's output after every row.
  Nine scenarios: doc create, structural update, text update, an update
  chain, diagram create plus --replace, a root doc lifecycle ending in
  doc delete, a table row removal, set-title, and a doc properties flip.
- check.mjs applies each sequence one row at a time to a real Y.Doc and
  asserts no throw, no pending structs or delete sets, an exact match
  against the y-octo view, and that encodeStateAsUpdate re-applies to a
  fresh doc unchanged. Five interleaving cases make an app-style edit with
  real yjs first and then apply the CLI delta computed without it.
- Two merge-semantics gaps are recorded as xfail: `doc update` replaces
  the note's sys:children and a changed paragraph's prop:text wholesale
  instead of editing in place, so concurrent app work inside those
  containers is dropped. Real yjs decodes the bytes correctly; this is
  write semantics, not an encoding divergence. A gap that starts passing
  fails the run with XPASS.
- The workflow now also triggers on the BlockSuite and app sources the CLI
  hardcodes conventions from, and tests/schema_drift.rs checks the block
  flavours and sys:version integers the CLI writes against the BlockSuite
  schema definitions in the checkout.
Every parser invocation took y-octo's default random client id, and every
peer that writes to a doc stays in its state vector forever, so an agent
editing a doc N times left N dead clients behind in every copy of it.

The id is now generated once per workspace and persisted in
`affine-cli.client` next to `storage.db`; `lease::doc_options()` is the
factory every production Doc is built from. Reusing an id is only safe for
a single writer, so that file doubles as the write lock: mutating commands
hold an exclusive advisory flock on it for their whole run and a second CLI
process retries briefly, then fails with the new `error:busy` instead of
minting colliding (client, clock) item ids. Read-only commands never take
the lease. Non-unix follows the InUseProbe::Unsupported pattern: the write
proceeds with a warning. A missing or malformed id file is regenerated with
a warning.

`doc create` now opens the store before building the page doc, since taking
the lease is what publishes the client id.
…urvive doc update

`doc update` replaced a container's `sys:children` with a new `Y.Array` and a
changed paragraph's `prop:text` with a new `Y.Text`. That makes the CLI update
authoritative for the whole container: a paragraph the app appended, or
characters the app typed, between the CLI's read and its write stayed in the doc
but stopped being reachable, because the map key now pointed at a different
type. The real-yjs harness recorded both as xfail (interleaving cases B and C).

The new `write::inplace` module splices the existing children array with the
minimal insert/remove operations from an LCS of the old and new order, and
applies a retain/insert/delete delta from a character-level LCS to the existing
`Y.Text`. Retained characters whose attributes changed are re-formatted with
`Retain { format }` rather than reinserted. A block with no container yet still
gets a fresh one, so `doc create` is unchanged, and each command still emits one
delta. `doc set-title` goes through the same text helper.

Both `KNOWN_GAPS` entries are removed from check.mjs; the harness now reports
cases B and C as passing under yjs 13.6.21.

Thanks for the deep review and apologies for the delayed response was busy with other commitments. I have addressed the findings from the review in 12 commits on top of dae0c0ea58 (head aee8fdacb2).

  • Build: ported to y-octo 0.1.0, Cargo.lock refreshed, --locked passes.
  • The five defects: digit escape, retained-id table sweep, prop:rows.order guard, build_stored_tree visited set, ungroupIndex in next_index. Each has a regression test.
  • Docs vs mechanism: clap errors now go through the JSON envelope (error:usage, exit 2); ensure_edgeless runs before the element push; "lock" is now documented as a pre-flight check with a Windows warning; and the CLI refuses to open a DB whose _sqlx_migrations differ from affine_schema (migration_required / db_newer, opt-in --allow-migrate). Connector endpoints are checked, --spec is capped, and the CLI keeps one y-octo client id per workspace behind a flock lease.
  • Harness: it now emits the exact per-row bytes the CLI pushes, including delete sets, and replays them row by row in real yjs 13.6.21, plus interleaved app edits. No encoding divergence in 302 checks. The interleaving did catch two merge bugs in the CLI's own writer (it replaced sys:children and prop:text wholesale, so concurrent app edits were dropped). Fixed in 689fbff0b3 by editing the existing Y.Array/Y.Text in place.
  • Drift: the workflow now triggers on the BlockSuite and app paths the CLI hardcodes, and a schema_drift test compares the CLI's flavour/version list against defineBlockSchema(...).

On the path forward:

affine_doc_loader: the public repo has not been created yet (0.1.7 on crates.io is built from crates/affine_doc_loader at 4e4a2c19, which is not in any public repository), so there is nothing to open a PR against. I prepared the series locally against the 0.1.7 tarball, re-derived per function in upstream formatting. PR A is math + the $$ trailing-text fix in one commit, then $ escaping with the digit fix in a second. PR B is the table/cycle/page-stub fixes. Every commit builds and passes tests on y-octo 0.1.0. @darkskygit, could you share the repo link when it is up, or a rough timeline? I will file both the same day.

y-octo harness: I also built a CLI-independent version for y-crdt/y-octo. One scenarios.json drives both y-octo and real yjs through the same ops in both directions, over nine delete-set-heavy scenarios. It found three real divergences: a bare Any::Array map value reads back as its last element in yjs; y-octo has no cleanupFormattingGap, so deleted formatted runs leave ContentFormat items live; and splitting a tombstoned run errors, which y-octo #60 fixes (all steps pass with it merged). Happy to open that PR on y-octo if you want it there.

122-131: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Bound the field scan to the current schema call.

field_after and version_after both search from the call offset to the end of the file. If one defineBlockSchema( call omits flavour: or version:, the scan silently reads the next call's value instead of panicking, so the guard can record a wrong flavour-to-version pair and mask real drift.

Pass an end offset (the next defineBlockSchema( / createEmbedBlockSchema( match index, or the file end) and slice the haystack to that region.

♻️ Proposed bounding
-fn version_after(src: &str, from: usize) -> Option<i32> {
-    let hay = &src[from..];
+fn version_after(src: &str, from: usize, until: usize) -> Option<i32> {
+    let hay = &src[from..until];
     let at = hay.find("version:")?;

Compute until in scan_upstream from the sorted set of call offsets, then pass it to both helpers.

466-468: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Fail with a labeled check instead of a TypeError when a fixture assumption breaks.

Several places dereference or destructure a lookup result without a guard:

  • Line 468 destructures the result of .find(...). If no paragraph reads Hello world, Node throws Cannot destructure property.
  • Line 384 destructures bySeq.get(seqName). If the manifest omits a sequence, the same crash occurs.
  • Lines 394, 411, and 520 index blocksByFlavour(...)[0] directly.
  • Line 93 and line 192 use value from surfaceElements, which returns undefined after its own checks already failed.

The run still exits non-zero, so CI stays red. The cost is diagnosability: this harness exists to explain a y-octo/yjs divergence, and an opaque TypeError stack hides which check broke. Report a check(...) failure and skip the block instead.

♻️ Example for interleave C
-  const [, para] = blocksByFlavour(doc, 'affine:paragraph').find(([, m]) => m.get('prop:text')?.toString() === 'Hello world');
+  const found = blocksByFlavour(doc, 'affine:paragraph').find(([, m]) => m.get('prop:text')?.toString() === 'Hello world');
+  check(`${label}: base paragraph fixture present`, found !== undefined, paragraphTexts(doc));
+  if (!found) return;
+  const [, para] = found;

a standalone `yjs@13.6.31` decoder confirms:
- bare `Any::Array` → `40` (last element), spread throws - reproduces the bug;
- wrapped `Any::Array([Any::Array([..])])` → plain `[10,20,30,40]`, spreads fine - the fix.

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Align the postmortem with the app-pinned compatibility check. The active tools/affine-cli/yjs-compat harness pins yjs@13.6.21, carries the labelXYWH assertions from this postmortem, and runs in CI. Update this section to cite the explicit 13.6.21 harness result, or document why the 13.6.31 probe is equivalent.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Fix fenced-code round-trip stability.

BlockDraft::push_text preserves trailing newlines from Event::Text, while MarkdownWriter::push_code_block always appends another newline. Each re-ingest/render pass can therefore add a newline to ordinary and embedded-backtick code blocks. Make the writer append the separator only when the code text does not already end with \n, then add two-pass equality assertions for both cases.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Bound the node count while building the stored tree, not after it.

visited blocks a true cycle, but Line 146 removes the id when the recursion leaves the node. A block that lists the same child id twice is therefore expanded twice, and the duplication compounds at every level. A corrupt doc with N nested list blocks that each repeat a child id produces up to 2^N StoredNode values.

check_limits runs at Line 66, after load_doc_state has already materialised the whole tree. The process exhausts memory before the limit is reached. test_update_ydoc_child_cycle_errors covers only the true-cycle case.

Count nodes during the recursion and fail once the count passes MAX_BLOCKS.

🛡️ Proposed guard
 fn build_stored_tree(block_id: &str, block: &Map, pool: &HashMap<String, Map>) -> Result<StoredNode, ParseError> {
     // A corrupt doc can make sys:children cyclic; fail instead of recursing until the stack
     // overflows. `visited` holds the ids on the current root-to-node path.
     let mut visited: HashSet<String> = HashSet::new();
-    build_stored_tree_inner(block_id, block, pool, &mut visited)
+    let mut budget = MAX_BLOCKS;
+    build_stored_tree_inner(block_id, block, pool, &mut visited, &mut budget)
 }
 
 fn build_stored_tree_inner(
     block_id: &str,
     block: &Map,
     pool: &HashMap<String, Map>,
     visited: &mut HashSet<String>,
+    budget: &mut usize,
 ) -> Result<StoredNode, ParseError> {
+    // A repeated child id is not a cycle, but it duplicates the subtree at every level, so
+    // cap the materialised node count before `check_limits` ever runs.
+    *budget = budget
+        .checked_sub(1)
+        .ok_or_else(|| ParseError::ParserError("block_count_too_large".into()))?;
     if !visited.insert(block_id.to_string()) {

Pass budget through the recursive call at Line 144 as well.

🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy lift

Do not grant an unlocked write lease on non-Unix platforms.

Mutating commands acquire WriteLease before their read-merge-write cycle. The non-Unix branch returns Ok(()), so concurrent processes reuse the persisted client ID without exclusion. They can create colliding (client, clock) identifiers and lose or corrupt updates. Implement a platform-native exclusive lock, or reject mutating commands before publishing the client ID.

Reject path-bearing workspace components before joining.

workspace_db_path joins raw peer and workspace_id. An absolute component replaces the preceding path, and .. can escape base. The storage connection then passes the resulting path to SQLite.

Validate both values as single normal path components before constructing paths. Apply the same validation to client_id_path and workspaces_dir.
