Subject: [PATCH 01/35] feat(memory-sources): disable auto-sync by default,
 lower GitHub limits, restyle toasts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Composio sources are still auto-registered but now default to
enabled=false so they don't burn tokens until the user explicitly
enables them. GitHub item limits lowered from 2000→1000 per type.
Toast notifications restyled with white card + colored left border
accent for a calmer look.

Subject: [PATCH 02/35] feat(github-sync): use local git for commits,
 repo-scoped chunk paths, granular progress

Commits now sync via bare git clone + `git log` instead of paginating
the GitHub REST API. Falls back to API on clone failure. Issues/PRs
stay on gh CLI/API as before.

Chunk store paths for GitHub items are now repo-scoped
(`document/github-org-repo/`) instead of per-item
(`document/github-org-repo-commit-<sha>/`), eliminating thousands of
directories in Obsidian.

Sync progress events now emit per-item for GitHub sources (vs every 5)
and include the new-item count in the message.

From 4f3b3d4161470f93954a7165793097b3f1ad4818 Mon Sep 17 00:00:00 2001
From: Steven Enamakel <enamakel@tinyhumans.ai>
Date: Sun, 31 May 2026 00:26:03 -0700
Subject: [PATCH 03/35] perf(github-sync): cache paginated list data to avoid
 re-fetching each issue/PR
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The paginated /issues and /pulls endpoints already return full body,
state, labels, etc. Previously we discarded this at list time and
re-fetched each item individually in read_item — N extra API calls
for no reason. Now list_issues/list_prs cache the full GhIssue/GhPr
in a module-level HashMap, and read_issue/read_pr consume from cache
first (only falling back to API on cache miss). Comments are still
fetched per-item since they're not in the list response.

For 1000 issues this cuts API calls from ~2010 to ~1010.

Subject: [PATCH 04/35] fix(memory-tree): use path_scope for source tree scope
 so GitHub items share one tree

Previously each GitHub commit/issue/PR got its own source tree because
the tree scope was the per-item source_id. Now when path_scope is set
(e.g. repo-scoped for GitHub), it's used as the tree scope instead.
All items from one repo land in a single source tree like
`source-github-tinyhumansai-openhuman` instead of thousands of
per-commit trees.

Subject: [PATCH 05/35] feat(memory-ui): push sync progress + tree events to
 frontend via Socket.IO
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds three Socket.IO bridges from the Rust event bus:
- memory:sync_stage — per-source sync progress (stage, detail, percent)
- memory:tree_progress — tree node seal events (namespace, level)
- memory:tree_completed — tree rebuild done (triggers graph refresh)

Frontend changes:
- socketService: listen for push events, dispatch window CustomEvents
- MemorySourcesRegistry: real-time progress bars with percentages per
  source, driven by push events instead of polling-only
- MemoryWorkspace: auto-refresh the graph when a tree build or source
  sync completes (2-3s debounce for worker drain)

Subject: [PATCH 07/35] fix(memory-tree): L0 seal gate uses token budget only,
 not item count

Remove the SUMMARY_FANOUT (10-item) gate from L0 sealing so small-token
items like commit messages (~20-50 tokens) accumulate into large batches
before sealing. A 50K token budget naturally batches hundreds of commits
into one merged summary. The time-based flush catches low-volume sources.

Subject: [PATCH 08/35] feat(memory-tree): fine-grained build progress events
 across the pipeline
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds MemoryTreeBuildProgress domain event with phase/step/tree_scope/
level/item_count/detail fields. Emitted at key points:

- extract: scoring, admitted/dropped
- append: buffering (leaf → tree L0)
- seal: summarising (N inputs → L{n+1}), embedding, persisting

Sub-phases inside seal_one_level (summarising, embedding, persisting)
give the frontend visibility into the LLM call, embed call, and disk
write separately.

Bridged to Socket.IO as memory:build_progress and forwarded to the
frontend via openhuman:memory-build-progress CustomEvent.

Subject: [PATCH 09/35] feat(memory-sources): per-source Build button that
 seals tree immediately

Adds memory_tree_flush_source RPC that calls force_flush_tree directly
(bypassing the job queue) with a per-scope mutex so concurrent clicks
are serialized. Each source row in the UI now has a Build button next
to Sync.

now strips the item suffix (commit:sha, issue:42, pr:99) and derives
github:org/repo as the tree scope, so even old data routes to one
shared tree per repo on re-extraction.

Subject: [PATCH 11/35] =?UTF-8?q?perf(github-sync):=20batch=20processing?=
 =?UTF-8?q?=20=E2=80=94=20no=20per-item=20API=20calls?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Issues and PRs now use the paginated list data directly (body, state,
labels, author, dates all come from the /issues?per_page=100 and
/pulls?per_page=100 responses). No more individual fetch per item, no
more per-item comments fetch. For 1000 items this drops API calls from
~2010 to ~20 (just the paginated pages).

Sync loop now processes items with bounded concurrency (10 at a time)
via futures::stream::for_each_concurrent instead of sequentially.

 =?UTF-8?q?=20=E2=80=94=20skip=20per-chunk=20extract=20queue=20entirely?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

GitHub items now bypass the extract_chunk → append_buffer job queue.
Instead, all items are read from the paginated API (already cached),
pushed directly into the L0 buffer in bulk, then force-sealed in one
shot. This means:

- 1000 commits = 10 API pages + 1 LLM summary call
- No per-chunk scoring, no per-chunk embedding, no per-chunk job queue
- Entity extraction and embedding happen at seal time on the summary

The per-item queue path is preserved for non-GitHub sources (Composio,
folder, RSS, etc.) where per-chunk extraction is valuable.

Subject: [PATCH 13/35] fix(github-sync): call summarise directly instead of
 buffer+seal
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The buffer/seal path requires chunks to exist in mem_tree_chunks for
hydrate_inputs to find them. The bulk path was pushing item_ids into
the buffer that didn't exist as chunks, causing "refused to seal empty
buffer". Fix: build SummaryInputs directly from the read content and
call summarise() in one shot. No buffer, no seal, no hydrate — just
one LLM call with all the items as input.

Subject: [PATCH 14/35] fix(github-sync): write raw archive files + summary .md
 to disk

The bulk path was calling summarise() but never persisting anything.
Now it:
1. Writes raw archive files per item during the read phase
   (raw/github-com-org-repo/{commits,issues,prs}/<ts>_<uid>.md)
2. Writes the summary as a .md file with YAML frontmatter in
   wiki/summaries/<repo-slug>/bulk-summary-<timestamp>.md

Subject: [PATCH 15/35] feat(memory): move GitHub sync to memory_sync/sources,
 add ingest_summary
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Move GitHub sync logic from memory_sources/sync.rs into
memory_sync/sources/github.rs where sync code belongs. Introduce
memory_tree::ingest::ingest_summary as the single-shape entry point
for landing pre-built summaries into a tree — stages the .md file to
wiki/summaries/source-<slug>/L1/, inserts the SummaryNode row, appends
to the L1 buffer, and cascades seals when the buffer crosses
SUMMARY_FANOUT. Embeddings are temporarily disabled.

Child wikilinks now point to actual raw archive paths so Obsidian can
resolve them.

Subject: [PATCH 16/35] feat(memory): per-source sync mutex + audit log with
 token/cost tracking

- Add per-source mutex to sync_source() so pressing the sync button
  twice doesn't run the same source concurrently.
- Add sync audit log (workspace/memory_tree/sync_audit.jsonl) that
  records each sync run: items fetched, batches, input/output tokens,
  estimated cost USD, duration, success/error.
- GitHub sync now reports token usage and cost in the completion event.

Subject: [PATCH 17/35] feat(memory): auto-rebuild tree from raw files during
 sync

When a sync completes, check if the source has raw archive files on
disk but no tree summaries (max_level == 0). If so, automatically
rebuild: read all .md files from raw/<source_slug>/, batch into 50k
token groups, summarise each batch, and ingest into the tree.

Fixes gmail (and other composio sources) where raw emails were written
to disk but the tree was never built due to interrupted sync or
missing worker queue processing.

+//! Rebuild tree from raw archive files on disk.
+//!
+//! When a sync has ingested raw files but never built summaries (e.g.
+//! interrupted sync, or legacy data), this module reads all `.md` files
+//! from `raw/<source_slug>/<kind>/`, batches them into ~50k-token
+//! groups, summarises each batch, and ingests into the tree via
+//! `ingest_summary`.
+//!
+//! Idempotent: re-running produces new L1 summaries (each has a unique
+//! id), so callers should check whether the tree already has L1 nodes
+//! before triggering.

Subject: [PATCH 18/35] fix(memory): retry failed pipeline jobs on sync trigger
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add retry_all_failed() to the job queue store — resets all terminally
failed jobs back to 'ready' with attempts=0 so the worker pool
re-processes them.

Called at the start of every sync_source dispatch, so pressing the
sync button in the UI clears the "225 failed jobs" state and lets the
pipeline continue processing through all documents.

Subject: [PATCH 20/35] fix(memory): skip embedding gracefully on rate limit
 instead of failing job
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The extract_chunk handler was propagating embedding failures (Voyage AI
429 rate limit) as job failures, causing 225+ jobs to exhaust retries
and go terminal. Now embedding errors are logged and the job continues
without a vector — the chunk is still scored, admitted, and written to
the tree. Embeddings can be backfilled later when the rate limit clears.

Subject: [PATCH 21/35] fix(memory): skip embedding in seal cascade on rate
 limit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The bucket_seal cascade was aborting the entire seal when the embedder
failed (Voyage 429 rate limit), leaving the buffer stuck and the seal
job retrying forever. Now embedding errors during seal are logged and
the summary is persisted without a vector — same graceful degradation
as the extract handler fix.

Subject: [PATCH 22/35] feat(ui): smooth graph updates without full remount
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Instead of destroying and recreating the Pixi WebGL context on every
data change, diff the node/edge arrays in-place:
- Existing nodes keep their positions and velocity
- New nodes spawn near their parent and animate into place
- The simulation reheats gently (alpha=0.3) so new nodes settle
  without disrupting the existing layout
- Camera (pan/zoom) is preserved across updates

Only a mode flip (tree ↔ contacts) triggers a full remount since the
edge semantics change. Data refreshes from sync events and manual
reloads now produce a smooth animated transition.

Subject: [PATCH 23/35] feat(graph): source root nodes, document leaves, orphan
 linking
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add synthetic orange "source" root nodes (one per tree scope, e.g.
  "GitHub · tinyhumansai/openhuman", "Gmail · stevent95@gmail.com")
- All parentless L-nodes and orphan chunks attach to their source root,
  giving the graph a proper tree shape instead of floating clusters
- GitHub L1 summaries expand their child_ids into document leaf nodes
  (commit/issue/PR labels) so the full depth is visible:
  source root → L2 → L1 → documents
- Frontend: source nodes render at radius 14 in orange (#F97316) with
  glow, appear in the legend, and show a distinct tooltip

Subject: [PATCH 24/35] fix(graph): bigger nodes at higher levels, don't attach
 orphan chunks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Summary node radius now grows with level: L1=7.5, L2=10, L3=12.5
  (was shrinking). Source roots are 16px. Chunks stay small at 3px.
- Only orphan L-nodes attach to source roots. Orphan chunks float
  freely as before — they connect to their parent_summary_id when
  sealed, no artificial source-root link.

Subject: [PATCH 27/35] feat(ui): sync audit history panel with token/cost
 tracking

Add openhuman.memory_sources_sync_audit_log RPC that reads the
sync_audit.jsonl file and returns entries most-recent-first.

New SyncAuditPanel component on the Memory tab shows:
- Summary row: total runs, total tokens in/out, total cost
- Table: when, source, items, tokens, cost, duration, success/fail
- Scrollable, most recent at top

Subject: [PATCH 29/35] fix(audit): log all sync kinds, not just GitHub

Move audit logging to the sync_source dispatcher level so every
source kind (Composio, Folder, RSS, WebPage) gets an audit entry
on success or failure. GitHub still writes its own detailed entry
with token breakdowns; other kinds get items + duration + error.
