- Introduced a new `position` column in the `chunks` table to maintain explicit document order during re-indexing.
- Updated migration to add the column without backfilling historical rows to avoid performance issues on large tables.
- Adjusted the `Chunk` model to reflect the new column without indexing, as ordering reads are document-scoped.
A single abandoned "idle in transaction" session held locks on the
documents table, which blocked the non-concurrent CREATE INDEX (hnsw)
run inside the FastAPI lifespan. Each API restart queued another
CREATE INDEX behind an advisory lock, leaving the server stuck at
"Waiting for application startup." indefinitely and freezing ingestion
writes.
Changes:
- setup_indexes(): build every index with CREATE INDEX CONCURRENTLY
(non-blocking ShareUpdateExclusiveLock) under a per-session
lock_timeout, and make each statement non-fatal so a contended/slow
build is retried next boot instead of wedging startup. Drop leftover
invalid indexes before rebuilding.
- create_db_and_tables(): apply lock_timeout to extension/create_all
DDL and gate the whole bootstrap behind DB_BOOTSTRAP_ON_STARTUP.
- engine: set idle_in_transaction_session_timeout (asyncpg) so an
abandoned transaction is reaped automatically.
- config + .env.example: DB_BOOTSTRAP_ON_STARTUP, DB_DDL_LOCK_TIMEOUT_MS,
DB_IDLE_IN_TX_TIMEOUT_MS.

Chunk ids stop reflecting document order once incremental re-indexing keeps
unchanged rows across edits. Backfill preserves the historical id ordering
so behavior is identical on day one.
- Updated environment variables and - configurations for credit purchases via Stripe, replacing legacy page pack system.
- Introduced auto-reload feature for credit top-ups and modified database models to track credit transactions.
- Updated notification system to handle insufficient credits and auto-reload failures.
- Adjusted API routes and schemas to reflect changes in credit management.
- Deleted the `search_surfsense_docs` tool and its associated files, streamlining the agent's toolset.
- Updated various components and prompts to remove references to the now-removed tool, ensuring consistency across the codebase.
- Adjusted documentation to direct users to the SurfSense documentation link for product-related queries instead.
- Updated `content_hash` in the `Document` model to remove global uniqueness, allowing identical content across different paths.
