- Add database/queries/{sources,rules,mappings,records}.sql — one file per
route, all business logic in PostgreSQL functions
- Replace parameterized queries in all four route files with lit()/jsonLit()
literal interpolation for debuggability
- Add api/lib/sql.js with lit(), jsonLit(), arr() helpers
- Fix get_view_data to use json_agg (preserves column order) with subquery
(guarantees sort order is respected before aggregation)
- Fix jsonLit() for JSONB params so plain strings become valid JSON
- Update manage.py option 3 to deploy database/queries/ instead of functions.sql
- Add SPEC.md covering architecture, philosophy, and manage.py

Clicking a column header reloads from page 1 with ORDER BY col ASC/DESC
NULLS LAST passed to the view query. Sort column is validated against
information_schema.columns to prevent injection. Pagination preserves
the active sort across prev/next.

- Express auth middleware checks Authorization: Basic header on all /api
routes using bcrypt against LOGIN_USER/LOGIN_PASSWORD_HASH in .env
- React login screen shown before app loads, stores credentials in memory,
sends them with every API request, clears and returns to login on 401
- Logout button in sidebar header
- manage.py option 9: set login credentials (bcrypt via node, writes to .env)
- manage.py status shows whether login credentials are configured

- Add get_all_values() SQL function returning all extracted values (mapped
+ unmapped) with real record counts and mapping output in one query
- Add /mappings/source/:source/all-values API endpoint
- Rewrite All tab to use get_all_values directly instead of merging two
separate API calls; counts now populated for all rows
- Rewrite export.tsv to use get_all_values (real counts for mapped rows)
- Fix save bug where editing one output field blanked unedited fields by
merging drafts over existing mapping output instead of replacing
- Add dirty row highlighting (blue tint) and per-rule Save All button
- Fix sort instability during editing by sorting on committed values only

Mirrors TPS's retain: y behaviour — when a mapping is applied, the extracted
value is also written to output_field so both the raw extraction and the
mapped result are available in transformed data.

- Restore export.tsv and import-csv endpoints to mappings routes
- sample column is always last in export and discarded on import
- get_unmapped_values now returns distinct source field values as sample instead of full raw records

- Switch apply_transformations from regexp_match to regexp_matches with
ORDINALITY, enabling the g flag to return all occurrences as a JSONB array
- Aggregate matches directly to JSONB in lateral subquery to avoid
text[][] type errors when subscripting array_agg results
- Pass flags as proper third argument to regexp_matches/regexp_replace
instead of inline (?flags) prefix — the only way g works correctly
- Apply same fix to preview and test endpoints in rules.js
- Add migrate_tps.sql script for migrating data from TPS to Dataflow

- Support multi-capture-group regex: mappings.input_value changed to JSONB,
regexp_match() result stored as scalar or array JSONB in transformed column
- Computed expression fields in generated views: {fieldname} refs substituted
with (transformed->>'fieldname')::numeric for arithmetic in view columns
- Fix generate_source_view to DROP VIEW before CREATE (avoids column drop error)
- Collapsible rule cards that open directly to inline edit form
- Debounced live regex preview (extract + replace) with popout modal for 50 rows
- Records page now shows dfv.<source> view output instead of raw records
- Unified field table in Sources: single table with In view, Seq, expression columns
- Fix "Rule already exists" error when editing by passing rule.id directly to submit
- Fix Sources page clearing on F5 by watching sourceObj?.name in useEffect dep

- POST /api/sources/suggest: derive source definition from CSV upload
- GET /api/sources/:name/import-log: query import history
- GET /api/rules/:id/test: test rule pattern against real records
- rules: add function_type (extract/replace) and flags columns
- get_unmapped_values: include up to 3 sample records per value
- npm start now uses nodemon for auto-reload
