Summary

v0.11.0 delivers collaborative editing (CRDT sync via yrs), org-dailies, and Editor struct decomposition — the three major themes of this release cycle.

Collaborative Editing (Phases A–F)

  • mae-sync crate: yrs CRDT text bridge + KB node schema
  • mae-state-server: standalone collab server with WAL-based SQLite persistence
  • Push-based sync event broadcasting, pull-based MCP sync methods
  • 3-tier E2E test suite (bridge, TCP, fault injection)
  • Save protocol (SHA-256 content-hash), heartbeat/keepalive, offline recovery
  • Git-based project identity (4-tier: git remote → .project → basename → FNV-1a)
  • Join-save model with suffix matching
  • 7 editor commands (SPC C prefix), 4 AI tools, Scheme API

Org-Dailies

  • Chain-fill navigation, audit report, activity tracking
  • Write-through safety (kb_write_guard anti-cascade)
  • Full property drawer parsing, schema v5
  • Dailies module with SPC n d keybindings

Editor Struct Decomposition (197 → ~69 fields)

  • CollabState (18 fields): collaborative editing state
  • ShellIntents (12 fields): shell/terminal intent queue
  • ViState (41 fields): vi modal editing state
  • AiState (34 fields): AI agent state
  • KbContext (21 fields): knowledge base, federation, config
  • DapContext (2 fields): debug adapter protocol state

Infrastructure

  • Scheme test framework (mae-test.scm + Rust orchestrator, TAP v14)
  • Criterion benchmarks (buffer_ops, crdt_ops)
  • MCP protocol hardening (5 bug fixes, 8 new tests)
  • Keymap flavor infrastructure (doom module)
  • KB integrity pipeline (stale detection, link validation, orphan cleanup)
  • dispatch/ui.rs split into 5 domain files
  • CONTRIBUTING.md naming conventions

Stats

  • 3,673+ tests passing
  • 20 crates, 19 modules
  • 60+ commits since main

Test Plan

  • make ci passes (fmt + clippy + check + test)
  • cargo clippy --package mae-gui --all-targets -- -D warnings
  • cargo test --workspace — 3,673 tests, 0 failures
  • Scheme tests: make test-scheme-all
  • TCP E2E: MAE_TCP_E2E=1 cargo test -p mae --test collab_tcp_e2e -- --ignored

feat: full property drawer parsing + schema v5 (Part 1)
9f265cd 
- Node struct gains `properties: HashMap<String, String>` for arbitrary
  org property drawer key-value pairs (foundation for activity tracking)
- org parser captures ALL properties, not just :ID:
- scan_heading_id → scan_heading_properties for heading-level drawers
- update_property() utility for rewriting single properties in-place
- SQLite schema v4→v5 migration: properties_json column
- 6 new tests (parse, round-trip, update_property, migration)

fix: kernel dailies bindings + set-group-name Scheme API + introspect…
d812323 
… version

- Add 5 dailies bindings (SPC n d t/y/d/p/n) to kernel keymaps.rs
  so they work without the dailies module being declared in (mae!)
- Mirror dailies bindings in keymap-doom module (intentional redundancy
  matching existing pattern for all other SPC bindings)
- Implement (set-group-name MAP PREFIX LABEL) Scheme API:
  - New pending_group_names field in SharedState
  - Registration in SchemeRuntime::new()
  - Drain in apply_to_editor alongside keymap bindings
  - Used by dailies module to set "+dailies" group label
- Add version + modules sections to introspect MCP tool output
  (agents can now verify build version and loaded module state)
- Tests: dailies_bindings_registered, spc_sub_prefixes_have_group_names,
  set_group_name_works, runtime_define_key_updates_keymap

feat: which-key scrolling, height config, sort order, group labels
ca9170d 
Which-key popup UX overhaul:

- Scrolling: C-j/C-k, C-n/C-p, Up/Down scroll by 1; C-d/C-u by 5.
  Directional indicators show count above/below visible entries.
- Height config: `which-key-max-height-pct` option (10-90%, default 40)
  replaces hardcoded 2/3 fraction. All 5 which-key options now have
  config_key for :set-save persistence.
- Sort order: `which-key-sort-order` option (key/desc/none). Groups
  always sort first.
- Shared layout: format_keypress() and which_key_column_layout() moved
  to text_utils.rs — both TUI and GUI renderers use the same function,
  eliminating height-vs-render mismatch bug.
- Group labels: 14 set-group-name definitions in keymap-doom (+ai,
  +buffer, +code, +eval, +file, +help, +peek, +notes, +open, +project,
  +quit, +select, +toggle, +window).
- Dailies cleanup: removed 5 duplicate define-key calls (bindings
  already in keymap-doom); module now only provides set-group-name.
- Editor helpers: set_which_key_prefix() / clear_which_key_prefix()
  ensure scroll resets on prefix change.
- Fix: UTF-8 safe truncation in AI grading (floor_char_boundary).
- 7 new unit tests for format_keypress and which_key_column_layout.

feat: server-client M1 — multi-client MCP, file safety, KB WAL, ADRs
6d77970 
Multi-client MCP server:
- Per-client tokio tasks with ClientSession (session.rs)
- Content-Length framing with line-based fallback for backward compat
- EditorEvent broadcast with per-client bounded channels (broadcast.rs)
- $/ping heartbeat, notifications/subscribe, 5s write timeout
- Initialize handshake extracts clientInfo, reports multiClient capability

File safety (layered defense):
- SHA-256 content-hash verification on buffer load/save/reload
- Advisory file locks (.{name}.mae.lock) with stale PID cleanup
- check_disk_changed_by_hash() catches mtime failures (NFS, sub-second)

KB hardening:
- WAL mode (concurrent readers), busy_timeout 5s, synchronous NORMAL
- New test: wal_mode_enabled

Shared code extraction:
- centered_popup_dims() + truncate_to_width() in text_utils (principle 8)
- TUI and GUI popup renderers deduplicated

File tree focus fix:
- Tree window receives focus on open (was staying on editing window)
- New option: file_tree_focus_on_open (default true, :set-save persistable)

Documentation:
- 4 ADRs in docs/adr/ (protocol, text sync, file safety, KB scaling)
- CLAUDE.md principle 10 (multi-client safety) + server-client section
- ROADMAP KB visibility/scoping/tangle items
- Makefile docs-tangle + docs-tangle-check targets

feat: mae-sync crate — yrs CRDT text bridge + KB node schema (20 tests)
a089796 
Implements the collaborative sync layer using yrs (Yjs Rust port, YATA algorithm)
as specified in ADR-002, ADR-005, and ADR-006. Provides:

- TextSync: YText <-> Rope bridge for collaborative text editing
- KbNodeDoc: CRDT schema for knowledge base nodes (YMap)
- Encoding utilities for state vectors and updates
- Stress convergence test (5 clients, 200 random ops each)

feat: Phase B — wire TextSync into Buffer for collaborative edits
5f09553 
Integrates mae-sync into mae-core so that buffers with sync enabled
generate yrs updates on every text mutation for broadcast to peers:

- Add `sync_doc: Option<TextSync>` + `pending_sync_updates` to Buffer
- Hook all 10 mutation methods (insert_char, delete_char_backward/forward,
  delete_line, delete_word_backward, delete_to_line_start/end,
  insert_text_at, delete_range, open_line_below/above)
- Undo/redo rebuild sync state from rope (correctness over efficiency)
- replace_contents/replace_rope recreate sync_doc preserving client_id
- Buffer::enable_sync/disable_sync/apply_sync_update public API
- MCP: sync/enable, sync/state_vector, sync/update protocol methods
- EventBroadcaster: SyncUpdate event variant for peer notification
- 6 new unit tests (all passing, 0 regressions in 2000+ test suite)

Zero-cost when sync disabled: all hooks are Option::map on None.

feat: Phase C — MCP sync method handlers (pull-based)
70c7811 
Wire up executor handlers for sync/enable, sync/state_vector, sync/update,
and sync/full_state so MCP clients can enable CRDT sync on buffers, exchange
state vectors, and apply remote updates. Pull-based model (clients poll).

- New sync_exec.rs dispatcher (4 handlers) in mae-ai executor chain
- Buffer lookup by name or index, idempotent enable, base64 transport
- sync/full_state added to MCP protocol method match
- mae-sync dependency added to mae-ai
- 7 unit tests including two-client roundtrip convergence

feat: Phase D — push-based sync event broadcasting (11 tests)
0bab9d2 
Wire the EventBroadcaster into the MCP server so subscribed clients
receive push notifications when buffers change. This closes the gap
where local edits queued yrs updates but nothing delivered them.

Key changes:
- McpServer gains SharedBroadcaster (Arc<Mutex<EventBroadcaster>>)
- handle_client restructured with tokio::select! for simultaneous
  request handling and event pushing
- notifications/subscribe now updates broadcaster filter
- write_notification helper sends JSON-RPC notifications (no id field)
- New sync_broadcast::drain_and_broadcast() drains pending yrs updates
  from buffers and broadcasts to subscribed clients
- Drain points: McpToolRequest (immediate), IdleTick/frame_timer (~100ms)

New tests:
- 2 broadcast unit: sync_update delivery + subscription filtering
- 4 drain unit: noop, clears pending, multiple buffers, skips non-sync
- 5 E2E integration: push after subscribe, no push before subscribe,
  two clients (one subscribed), survives disconnect, backpressure

fix: audit fixes for sync/MCP push architecture
9c7fd7e 
Address 6 findings from the Phase A-D architecture review:

Finding 2 (HIGH — Bug): reload_from_disk() now calls sync_rebuild_from_rope()
  to keep yrs doc in sync with rope after file reload.

Finding 3 (MEDIUM): replace_rope() and replace_contents() now use
  sync_rebuild_from_rope() instead of inline doc recreation, which
  also queues the update for broadcast.

Finding 4 (MEDIUM): remove_buffer_raw() logs a warning when dropping
  pending sync updates on buffer close.

Finding 10 (MEDIUM): Push notifications now include per-client `seq`
  number in params for event ordering. Notification format changed
  from `params: event` to `params: { seq, event }`.

Finding 11 (HIGH — Design): sync_rebuild_from_rope() documented as
  creating a fresh Doc (discarding CRDT history). TODO added for
  incremental diff approach in Phase E.

Finding 1 (MEDIUM): session.subscriptions documented as informational
  copy; broadcaster is the authoritative source for delivery.

…ervability

Phase 1 — Scalability:
- SQLite sharded connection pool (FNV-1a, 4 shards default) in state-server
- CRDT-safe undo via reconcile_to() (LCS diff, preserves vector clocks)
- DocAddress type (file:/kb:/shared: namespaces) for document addressing
- Event sequence tracking (wal_seq on SyncUpdate for gap detection)
- Save protocol (SHA-256 content-hash verification)
- Background compaction + idle eviction in state-server

Phase 2 — UX:
- CollabStatus enum + 3 editor fields (status, synced_docs, intent)
- 5 collab options (server_address, auto_connect, auto_share, etc.)
- 7 commands (collab-start/connect/disconnect/status/share/sync/doctor)
- SPC C keybinding group in doom keymap
- Status bar segment (priority 4, shows connection state + peer count)
- Splash screen quick action (SPC C c)
- init.scm section 6 "Collaborative Editing"

Phase 2 — AI Tools:
- 4 AI tools: collab_status, collab_connect, collab_share, collab_doctor
- Tool definitions with parameter schemas and permission tiers
- Intent-based dispatch (core sets intent, binary drains each tick)

Phase 3 — Observability:
- mae doctor: collab section (binary, env, config checks)
- audit_configuration: collaboration JSON section
- State-server: sync/resync, docs/stats, docs/save_intent,
  docs/save_committed, $/debug handler methods

30 files changed, 1,130 insertions, 3 new files.
3,336 tests passing, 0 clippy errors.

Phase 3 (observability):
- introspect tool: new "collaboration" section with status/server/synced docs
- Scheme API: (collab-status) alist, (collab-synced-buffers) list
- $/debug method: uptime_secs, connection_count, version fields
- handler.rs: server_start_time threading for uptime tracking

Phase 5 (documentation):
- KB concept nodes: collab-architecture, collab-workflows
- KB lesson node: collab-setup (install → configure → connect → share)
- docs/COLLABORATION.md: standalone guide (architecture, quickstart, config, debugging)

Phase 6 (tests):
- E2E network tests: tcp_docs_stats, tcp_save_intent_ok, tcp_resync_protocol, tcp_debug_endpoint
- Sync tests: reconcile_to_empty, reconcile_from_empty
- Core dispatch tests: 4 collab dispatch unit tests
- Status bar format_collab_status tests

All 3,324+ tests pass, 0 clippy warnings.

feat: KB CRDT integration — schema v7, Node↔KbNodeDoc bridge
34dc95a 
Phase 4 of the collaborative editing plan:

- Schema migration v6→v7: adds `crdt_doc BLOB` column to nodes table
- Node.crdt_doc field: optional encoded yrs document bytes
- Node.to_crdt_doc(): creates KbNodeDoc from text fields or restores from bytes
- Node.apply_crdt_doc(): updates title/body/tags from CRDT content
- save_to_sqlite/load_from_sqlite/sync_to_sqlite: persist crdt_doc column
- Backward-compatible: older DBs auto-migrate, crdt_doc defaults to NULL
- mae-kb now depends on mae-sync for KbNodeDoc access

Tests: migration v6→v7, CRDT roundtrip via save/load, Node↔KbNodeDoc
conversion, apply_crdt_doc field updates (132 KB tests pass).

fix: Scheme test framework — 5 gap fixes + execute-ex + Rust-side ite…
13518ad 
…ration

- scheme/lib/mae-test.scm: describe/it/should/wait-until/run-tests (TAP v14)
- crates/mae/src/test_runner.rs: headless event loop test runner with
  Rust-side test iteration (inject/apply between each test step)
- crates/mae/src/main.rs: --test, --test-filter, --test-output CLI flags
- crates/scheme/src/runtime.rs: 9 new primitives (exit, write-file,
  sleep-ms, file-exists?, current-milliseconds, goto-char, buffer-string,
  buffer-text, execute-ex)

Gap fixes:
1. (execute-ex CMD) routes through ex-command parser (supports arguments)
   — enables (execute-ex "collab-join test.txt"), (execute-ex "w /path")
2. save-as via execute-ex: (execute-ex "saveas /path") or (execute-ex "w /path")
3. collab-join with args via execute-ex (was blocked by run-command)
4. Buffer state refresh between test steps — Rust-side iteration with
   sync_scheme_state (set! for mutable binding cells) solves Steel's
   register_value shadowing behavior
5. Error messages now use error-object-message (was showing "<?>")

Steel upstream bug: (void) in tail position crashes — SteelVal::Void
missing from handle_tail_call() match arm. Workaround: use #t instead.

- tests/collab-e2e/: 6 test files + helpers + verify.sh + docker-compose
- Makefile: test-scheme + docker-collab-test targets
- Collab E2E tests use fixed sleep-ms delays (no wait-until polling)
  and Rust-side iteration (no run-tests call)

feat: CRDT test primitives + editor tests + testing framework docs
8db90c9 
Add Scheme primitives for CRDT/sync testing (buffer-enable-sync,
buffer-drain-updates, buffer-apply-update, buffer-encode-state, etc.)
using the SharedState pattern to bypass Steel binding scope issues.

New test suites:
- tests/crdt/ (35 tests): sync enable/disable, two-buffer convergence,
  undo with sync active
- tests/editor/ (22 tests): insert/delete/replace, mode transitions,
  undo/redo

Infrastructure: recursive test file collection, SharedState-backed
get-buffer-by-name and current-mode, should-mode assertion helper.

Docs: CLAUDE.md testing framework section, KB concept nodes
(scheme-testing, test-runner), 9 scheme API nodes for test functions.

…cle, user story E2E

Testing framework enhancements:
- should-error + should-match assertions in mae-test.scm + KB nodes
- Region state forwarding (visual mode) via SharedState
- buffer-search-forward primitive for in-buffer search
- Option values forwarding (get-option reads fresh state each step)
- Initial sync_scheme_state before first test (fixes mode check on step 0)

CRDT lifecycle tests (5 new files, 116 steps):
- Concurrent edits: two buffers insert at same position, exchange, converge
- Three-client: independent edits → full exchange → byte-identical convergence
- Collaborative undo: A inserts, B extends, A undoes (documents known bug)
- State vector: incremental sync via encode-state-vector + compute-diff
- Reconcile: buffer-reconcile-to generates valid CRDT update for peers

New CRDT primitives (Rust):

feat: CRDT robustness hardening — ADR-008, runtime limits, CI fixes, …
3e51263 
…3,629 tests

Phase 1: ADR-008 CRDT target metrics (50 clients/doc, 10MB max, <50ms p99)
Phase 2: Critical fixes — atomic compaction, share_doc error handling,
  collab_bridge unwrap elimination, handler param validation, named constants
Phase 3: Runtime enforcement — max_documents, max_update_size (1MB reject),
  max_wal_entries (forced compaction), max_document_size (warning)
Phase 4: 4 new Scheme-accessible collab options (max_pending_updates,
  reconnect_backoff_factor, max_reconnect_attempts, batch_update_ms)
Phase 5: 26 new tests (DAP failure, sync encoding edge cases, doc_store
  limits, handler validation, test library assertions)
Phase 6: TESTING.md + CLAUDE.md updated

CI fixes:
- when-flag arity mismatch (format module) — 3 args not 2
- SPC t s keybinding conflict (spell → SPC t S)
- Collab docker e2e now runs on PRs (was push-only)
- Steel home directory created in CI
- Removed phantom mae-test-fixtures exclude

feat: join-save model, suffix matching, CI warning fixes — 3,639 tests
782d54f 
Join-save model (industry standard): joined collab buffers have no auto
file_path. Users must :saveas to persist locally. Opt-in project path
mapping via collab_auto_resolve_paths + MiniDialog prompt.

Server-side suffix matching: sync/resync resolves bare filenames
(e.g. "test.txt" finds "file:no-project/test.txt"), fixing the Docker
collab E2E doc_id mismatch bug.

CI warning fixes: SPC t S→SPC t Z (spell conflict), removed duplicate
SPC c f (format owns it), fixed when-flag TailCall error in format
module (wrap body in lambda).

New: 3 collab options, CollabResolvePath MiniDialog, descriptive save
error messages, 16-step Scheme join-save test, ROADMAP E1-E8 + KB
fuzzy body search item.

fix: collab test failures (get-option freshness, missing option arms)…
1b47fcd 
… + tiered CI

Bug fixes:
- get-option now reads from SharedState (fresh after sync_scheme_state)
  instead of a closure-captured snapshot from inject_editor_state
- Added missing get/set_option arms for collab_auto_resolve_paths,
  collab_default_save_dir, collab_save_on_remote_update
- Added corresponding fields to Editor struct with defaults
- Fixed saveas test path (parent dir must exist for atomic save)

Tiered CI (Makefile):
- make ci: fmt + clippy + check + test + Scheme editor tests + check-config + code-map
- make ci-extended: ci + CRDT Scheme tests + docker-smoke + docker-new-user
- make ci-docker-e2e: Docker collab E2E (on-demand)
- make ci-complete: everything (mirrors GitHub CI)

Updated TESTING.md with tiered CI docs and new test files.

16/16 collab join-save tests pass, 260/260 editor tests pass.

fix: split collab E2E test steps for pending op ordering
ab7bff5 
open-file, buffer-insert, and switch-to-buffer are all pending
operations processed by apply_to_editor in fixed order (insert
before open-file before switch-buffer). Combining them in a single
test step caused buffer-insert to target the wrong buffer (scratch
instead of test.txt), explaining the Docker E2E failure.

ca6c202 
…ab data model v2

Wire the save protocol end-to-end so `:w` on synced buffers triggers
`docs/save_intent` (SHA-256 content hash) → `docs/save_committed`
(broadcast to peers). Add `docs/metadata` endpoint exposing save_epoch,
last_saved_by, and connected_clients. Enhance disconnect UX (peer_count=0
status message). Document disconnect lifecycle in COLLABORATION.md.
Clean up 5 stale ROADMAP stub audit items and document undo+CRDT limitation.

8 new tests for save protocol flow (3,567 total, 0 failures).

feat: protocol resilience — gap detection, heartbeat, offline recover…
b8d4b6a 
…y, git identity

WU1: Client-side WAL sequence gap detection. Tracks wal_seq per doc in
the collab background task. Sequence gaps trigger ForceSync (resync).

WU2: Heartbeat/keepalive. 30s interval sends $/ping, logs latency on
response. Missed pong triggers disconnect. Configurable via
collab_heartbeat_interval option.

WU3: Offline edit recovery. Disconnect preserves sync_doc and
collab_doc_id instead of clearing them. Sets collab_offline flag on
buffers. Reconnect re-shares offline buffers via ForceSync. Status bar
shows [C:OFFLINE] during disconnection.

WU4: Git-based project identity. compute_project_identity() uses 4-tier
fallback: git remote URL (normalized) → .project TOML name → directory
basename → FNV-1a of absolute path. Cross-machine collab now works when
both sides share the same git remote.

WU5: Performance benchmark suite using criterion. Buffer ops (create,
insert, text extraction) in mae-core, CRDT ops (create, encode, apply
update, reconcile) in mae-sync. Makefile targets: bench, bench-save,
bench-compare.

WU6: Split dispatch/ui.rs (1,250 lines, 113 match arms) into 5 domain
files: help.rs, terminal.rs, project.rs, kb.rs, config.rs. Each gets a
dispatch_* method chained in dispatch_builtin_inner(). Remaining ui.rs
handles dashboard, AI, palette, describe, link editing, and demos (~400
lines). Matches existing pattern (dispatch/collab.rs, dap.rs, git.rs).

refactor: extract CollabState + ShellIntents sub-structs from Editor …
2e17808 
…(30 fields)

Extract 30 fields from the Editor struct into two cohesive sub-structs:

- CollabState (18 fields): collab_status, collab_server_address,
  collab_synced_buffers, etc. → editor.collab.*
- ShellIntents (12 fields): pending_shell_spawns, pending_shell_inputs,
  shell_viewports, etc. → editor.shell.*

Reduces Editor from ~100+ to ~80+ fields. Uses direct field access
pattern (self.collab.status) matching existing self.window_mgr,
self.diagnostics, self.search_state patterns. No Deref, no accessors.

Mechanical rename across 25 files, zero behavior changes.
3,674 tests pass, 0 clippy warnings.

test: collab E2E — save round-trip, heartbeat, reconnect re-share
ec5c06e 
Add 5 protocol-level E2E tests to collab_bridge_integration.rs:

- save_intent_to_committed_roundtrip: SHA-256 hash check, save_epoch
  increment, save_committed broadcast to second client
- save_intent_conflict_on_hash_mismatch: wrong hash returns "conflict"
- heartbeat_ping_pong_and_server_drop: $/ping → "pong", server abort
  → EOF detection (no hang)
- reconnect_reshare_preserves_crdt_state: share → edit → server crash →
  fresh server → re-share with preserved CRDT → content matches

Also adds ping(), save_intent(), save_committed() helper methods to
the Client test infrastructure.

refactor: extract ViState + AiState sub-structs from Editor (75 fields)
d344094 
Extract two major field groups from the Editor struct into dedicated
sub-structs, continuing the pattern from CollabState + ShellIntents:

- ViState (41 fields): vi-modal editing state — operators, counts,
  registers, marks, macros, visual selection, command-line, jump/change
  lists, and dot-repeat. Access via `editor.vi.*`.

- AiState (34 fields): AI session state — provider config, token
  counters, streaming flags, conversation pair, permission tier, and
  target context. Access via `editor.ai.*`. Field names strip the
  `ai_` prefix (e.g. `ai_streaming` → `ai.streaming`).

Editor struct drops from ~100+ fields to ~40 after all 4 extractions
(CollabState, ShellIntents, ViState, AiState). All 3,694 tests pass,
clean clippy.

refactor(core): standardize test variable names to editor
7561af3 
Mechanical rename across 31 test files (366 occurrences):
- `ed` → `editor`, `ed2` → `editor2` in all test bindings
- `ed_with_text()` → `editor_with_bulk_text()` (signals bulk insertion)
- `ed_with_rust()` → `editor_with_rust()` (consistent prefix)
- Add doc-comments to all three test helpers explaining semantics

No logic changes — purely naming consistency matching production code.

refactor(core): extract KbContext sub-struct from Editor (21 fields)
19283ae 
Move all knowledge-base fields into `editor::kb_state::KbContext`:

- Federation (registry, instances, watchers) → `editor.kb.{registry,instances,...}`
- Config (watcher_enabled, search_max_results, etc.) → `editor.kb.*`
- Capture state → `editor.kb.capture_state`
- AI context (visited IDs, write guard) → `editor.kb.{ai_visited_ids,write_guard}`

Editor field count: ~92 → ~71 (21 fields extracted).
Follows same pattern as ViState, AiState, CollabState, ShellIntents.

20 files updated across mae-core, mae-ai, mae-scheme, mae (binary).
All 3,673 tests pass. Clippy clean (workspace + GUI).

fix(collab): buffer status indicators, save guard, sharer notificatio…
8de53b8 
…ns, reconnect backoff

WU1 — Per-buffer collab status indicators (E8):
- Add `collab_is_sharer` field to Buffer (default false)
- `format_collab_status` shows role + pending updates:
  [C:3|sharer], [C:3|synced], [C:3|pending:2], [C:OFFLINE|pending:5]
- Set `collab_is_sharer = true` on BufferShared event

WU2 — Fix `:w` for non-sharer clients (Bug 2):
- Guard `SaveCollab` intent behind `collab_is_sharer`
- Joiners save locally only, no `save_intent` broadcast

WU3 — Sharer quit notification (Bug 3):
- Add `SharerLeft` variant to EditorEvent + CollabEvent
- Track `sharer_session_id` on DocEntry in state server
- On sharer disconnect, broadcast SharerLeft to peers
- Client-side: parse notification, display status message

WU4 — Reconnect lifecycle hardening (Bug 4):
- Exponential backoff: base * factor^min(attempt, 5), capped at 300s
- Max reconnect attempts (0 = infinite, configurable)
- ForceSync debounce: skip duplicate requests within 2s per doc
