592d12958f Find candidate funds NOT in the DB: exhaustive EDGAR 497-universe pass 
fundlab/edgar_universe.py - the 'search' for funds we don't have:
  1. SEC full-index (Archives/edgar/full-index/YYYY/QTRn/company.gz)
     lists every filing; CIKs that filed a base 497/497K in the past 4
     quarters = every currently-active US open-end fund (1,668).
  2. one small fetch per CIK: the full-submission .txt carries the
     line-based SGML prospectus cover (<SERIES-NAME> ... unclosed
     <CLASS-CONTRACT-TICKER-SYMBOL> tags) - fund name + every class
     ticker, often several funds per filing.
  3. alpha-leaning name filter (expanded dbmine PATTERN: +relative
     value, risk allocation, dynamic global, real return, hedged),
     drop local-DB + shortlist tickers,
  4. Yahoo chart verify: instrumentType MUTUALFUND (OTC open-end;
     exchange name is useless - OTC funds report 'Nasdaq'),
     >=5y daily history,
  5. share-class dedupe (longest history), goget download, same
     screen_fund engine.
  Resumable (per-CIK covers cache), 4-thread, Range-free small files.

First pass results (46 funds screened, 5 NEW candidates):
  egrix/ecgmx Eaton Vance Global Macro Absolute Return: R2 0.07,
    +7.9%/+4.8% 5y alpha, t 4.9/4.6, corr-port 0.22 - pure macro idio
  dmszx Destinations Multi-Strategy Alternatives: R2 0.57, +3.3%, t3.5
  cbhax Victory Market Neutral Income: R2 0.07, +4.6%, t2.9, corr 0.11
  pdinx Putnam Diversified Income: semi-alpha (full t5.8, 62% 6m+)
  (+ wmnux/gioax = 2nd share classes of already-known candidates)
  vmnix Vanguard MN: alpha but corr 0.35 (portfolio already 50% MN)

app Fund Lab alpha table now also reads search_external.json.
tests: parse_cover unit tests (unclosed-tag SGML, ticker series
attach, malformed rejected). 65/65 fundlab, 32/32 app.

54d26939dc Fund Lab: N-PORT holdings page for the 16-fund shortlist 
- 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)

4f36bc7aea app: background cache refresh, per-benchmark stats, correlation tab, global date range 
- 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

d8703a7a63 Stock & Portfolio Analyzer: full UI rework 
- 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
