- fundlab/nport.py: parse the fund's own category/percentage lines,
as-of date, net assets and dollar-valued positions from N-PORT
schedules of investments (handles per-fund and combined multi-fund
family filings; conservative keyword bucketing of positions)
- fundlab/nport_cache/<sym>.json: parsed snapshots for 15 of 16 funds
(raw SOI HTML kept locally, gitignored; source URLs + filing dates in
nport_manifest.json, md5-verified against EDGAR)
- atesx: no current SOI found (Anchor's recent filings cover the Income
fund) - listed with an honest note
- app.py: new 'Fund Lab' tab - pick a fund, see objective, reported
composition (bar + table), rough keyword buckets, top positions, and
the prospectus strategy excerpt
- tests: parser unit tests (section finding, category regex, buckets)
- data.py: non-blocking load_bundle(); background watcher thread refreshes
the parquet cache (5s scan, 30s min rebuild cadence); refresh()/
up_to_date()/generation()
- statistics tab: one table per benchmark (vs <label>), plain column names
(beta/alpha/return/vol...), selectable+reorderable stat list in
settings.json
- correlation tab: per-portfolio components-vs-benchmarks +
all-portfolios-vs-benchmarks; numbered columns
- global date range (window radio + start/end boxes) applied to all tabs;
metrics.xcorr(); equity window radio gains YTD/3M/1M
- single spec grammar for symbol and benchmark fields: commas join one
portfolio (MSFT:0.6,V:0.4), spaces separate distinct symbols/portfolios;
both fields accept one or many entries
- benchmarks simulated with the same scheme/cost/tax rules; per-benchmark
beta/alpha columns; after-tax benchmark curves
- global Curve mode (pre/after/both) above the tabs; clean names in
single-curve mode
- live updates: field commits on Enter/blur, page recomputes per rerun;
portfolio+tax sims cached (st.cache_data); plotly.js from CDN (4.6MB ->
browser-cached) with F_INLINE_PLOTLY=1 offline fallback
- chart: legend underneath, solid lines, pan sticks to data edges
(width-preserving), zoom edge-clamped
- inputs persist in settings.json across reloads/restarts/devices
- tests: tests/test_app.py (AppTest) + tests/test_e2e_browser.py
(Playwright) via ./run_tests.sh
