Since June 2026 IDX publishes the monthly "Pemegang Saham di Atas 1%"
list as an XLSX workbook on the Data Kepemilikan Saham page instead of
a PDF announcement. Add a parser for it and accept `.xlsx` in
`ownership import --file`.
- src/ownership/xlsx.rs: zip + quick-xml reader (shared strings incl.
rich text, sheet cells), exact 12-column header match so the daily
above-5% and investor-type/classification workbooks are rejected,
Excel serial dates, numeric shares, percent -> bps with float-noise
rounding. Builds KseiHoldingDraft directly and reuses the entity
normalizers, so investor types stay uppercase like the PDF path.
- Fixtures: trimmed excerpts of the real 2026-08-31 above-1% and
2026-09-23 above-5% workbooks.
- Unit + CLI tests: import, ticker, releases, above-5% rejection.
- Docs: ARCHITECTURE parser pipeline, AGENTS ownership inputs.

- sanitize_current_ratio: and_then if/else -> filter
- screener/graph sorts: sort_by with reversed cmp -> sort_by_key(Reverse)
- insert_ksei_holdings_rows: manual Result match -> ?
Fixes the Clippy step on ubuntu-latest (rust 1.97) that the nix
toolchain (1.93.1) did not flag.
The April 2026 IDX ownership PDF omits the zero-valued scrip column for
some holders, causing the parser to leave holdings_scripless/scrip as
empty strings. This broke normalize_ksei_row which called parse_id_number
on empty input.
Two-layer fix:
- Parser: pop_numeric_tail handles 2-column (missing scrip) rows by
defaulting scrip to "0"
- Normalizer: parse_id_number_or_zero backstop treats empty component
share fields as 0 while still requiring total_shares
Also includes AGENTS.md refresh, formatting cleanup (rustfmt), and
version bump to 0.2.2.

Refactor KSEI PDF parsing for the live above-1 holder-register layout, add IDX announcement discovery plus browser-impersonated PDF fetches, and update the ownership docs to mark Batch 1 complete and scope Batch 2 around above1 hardening and unsupported legacy inputs.
- Change resolve_symbol return type from String to Result<String, IdxError>
- Add early validation for empty/whitespace-only ticker input
- Return Err(IdxError::InvalidInput) for empty tickers
- Add InvalidInput variant to IdxError enum
- Update all 15 callers in cli/stocks.rs to handle Result with ? propagation
- Update tests: empty/whitespace tickers now return error
Fixes#7
MSN Finance/Charts does not serve OHLCV data for XIDX stocks (returns 404).
Following the FP principle of not exposing capabilities a provider cannot fulfil:
- Remove impl HistoryProvider for MsnProvider entirely
- Remove fetch_charts from MsnClient
- Remove parse_chart_history, resample_history, trim_history_to_period from map.rs
- Remove MsnChart, ChartSeries, RawChart from raw_types.rs
- Remove parse_history_from_str, parse_close_only_history from parse.rs
- Decouple HistoryProvider from MarketDataProvider trait bound
- Add history_provider() factory: returns None for MSN, Some(Yahoo) for Yahoo
- CLI gates History/Technical on history_provider(), fails fast for MSN
- MSN mock returns Err(Unsupported); tests verify the behaviour explicitly
Add MsnProvider implementing MarketDataProvider trait with quote,
fundamentals, and history support. Includes provider-aware config
(file/env/CLI), cache namespace isolation per provider, symbol ID
mapping via embedded TSV, OHLCV resampling, and comprehensive unit
+ integration tests with MSN fixture data.
Key changes:
- MsnProvider with quote, key-ratios, and chart endpoints
- ProviderKind enum (yahoo/msn) with config hierarchy support
- Provider-namespaced cache buckets to prevent cross-provider poisoning
- Provider-aware MockProvider loading correct fixtures per provider
- Integration tests for config round-trip and cache isolation

- Add analysis module: SMA, EMA, RSI(14), MACD(12,26,9), volume ratio
- Add signal interpretation: bullish/bearish/neutral with consensus voting
- Wire up 'stocks technical <SYMBOL>' CLI subcommand
- Table output with colored signals + JSON output support
- Cache/offline/stale-cache fallback (same pattern as quote/history)
- Fetch 1 year of daily data for SMA200 coverage (~250 trading days)
- Add TechnicalReport, MacdSnapshot, VolumeSnapshot structs
- Add 4 new unit tests + 3 integration tests (30 total passing)
