## Split `audit.zig` into per-broker reconcilers — priority LOW ## Split `audit.zig` into per-broker reconcilers — priority LOW

It still bundles three logically distinct responsibilities:
- Portfolio hygiene check (no-flag mode) - Portfolio hygiene check (no-flag mode)
- Fidelity positions CSV reconciler (`--fidelity`) - Fidelity positions CSV reconciler (`--fidelity`)
- Schwab per-account positions CSV reconciler (`--schwab`) - Schwab per-account positions CSV reconciler (`--schwab`) and
- Schwab account-summary stdin parser (`--schwab-summary`) Schwab account-summary stdin reconciler (`--schwab-summary`)
The brokerage parsers themselves are split per broker:
`src/brokerage/types.zig` (shared `BrokeragePosition` +
`parseDollarAmount`), `src/brokerage/fidelity.zig` (Fidelity CSV +
option-symbol matcher), `src/brokerage/schwab.zig` (per-account
CSV + summary paste). Adding a new broker is a one-file add next
to those. What's left is splitting the *reconciler*
(compare-portfolio-vs-brokerage) and *display* code in audit.zig
into per-broker files that consume those parsers.

//! Fidelity export parsers.
//!
//! Parses the CSV produced by Fidelity's "Download Positions" feature,
//! plus the structured option-symbol matching used to tie a Fidelity
//! option row back to a portfolio lot.
//!
//! ## Limitations of this CSV parser
//!
//! 1. NOT a general-purpose CSV parser. It handles the specific format
//! exported by Fidelity's "Download Positions" feature.
//!
//! 2. Does NOT handle quoted fields containing commas. Fidelity's export
//! does not quote fields with commas in practice (description fields
//! use spaces, not commas), but a truly compliant RFC 4180 parser would
//! need to handle "field,with,commas" as a single value.
//!
//! 3. Does NOT handle escaped quotes ("" inside quoted fields).
//!
//! 4. Does NOT handle multi-line values (newlines inside quoted fields).
//!
//! 5. Assumes UTF-8 with optional BOM (which Fidelity includes).
//!
//! 6. Stops parsing at the first blank line, which separates position data
//! from the Fidelity legal disclaimer footer.
//!
//! 7. Hardcodes the expected column layout. If Fidelity changes the CSV
//! format (adds/removes/reorders columns), this parser will break.
//! The header row is validated to catch this.
//!
//! 8. Dollar values like "$1,234.56" and "+$1,234.56" are stripped of
//! $, commas, and leading +/- signs. Negative values wrapped in
//! parentheses are NOT handled (Fidelity uses -$X.XX format).
//!
//! 9. Money market rows (symbol ending in **) are treated as cash.
//!
//! For a production-grade CSV parser, consider a library that handles
//! RFC 4180 fully (quoted fields, escaping, multi-line values).

//! Schwab export parsers.
//!
//! Parses two distinct Schwab inputs:
//!
//! 1. The per-account positions CSV exported from Schwab's website
//! (Accounts → Positions → Export). One file per account.
//!
//! 2. The freeform account-summary text the user pastes from
//! Schwab's Accounts overview page. One paste covers all
//! accounts at once but only carries cash + total-value
//! aggregates, no per-position detail.
//!
//! ## Schwab CSV — limitations
//!
//! 1. NOT a general-purpose CSV parser. Handles Schwab's specific export
//! format where every field is double-quoted.
//!
//! 2. Handles simple quoted fields ("value") but does NOT handle escaped
//! quotes ("value with ""quotes"" inside") or multi-line quoted fields.
//! Schwab's export does not use these in practice.
//!
//! 3. The account number and name are extracted from the title line:
//! "Positions for account <NAME> ...<NUM> as of ..."
//!
//! 4. Rows with symbol "Cash & Cash Investments" are treated as cash.
//! The row with symbol "Positions Total" is skipped.
//!
//! 5. Hardcodes the expected column layout. If Schwab changes the CSV
//! format, this parser will break. The header row is not validated
//! beyond being skipped.
//!
//! ## Schwab summary — limitations
//!
//! The expected paste format is repeating blocks of 2-3 lines per
//! account:
//!
//! Account Name
//! Account number ending in NNN ...NNN
//! Type IRA $46.44 $227,058.15 +$1,072.88 +0.47%
//!
//! 1. NOT a CSV parser — parses freeform text pasted from the Schwab UI.
//!
//! 2. Identifies account blocks by the "Account number ending in" line.
//! The account name is the non-empty line immediately before it.
//!
//! 3. The values line (cash, total, change, pct) is identified by finding
//! dollar amounts. It tolerates missing or extra fields — it looks for
//! the first two dollar amounts as cash and total value.
//!
//! 4. Skips summary lines like "Investment Total", "Day Change Total",
//! and "Day Change Percent Total" which appear at the end of the paste.
//!
//! 5. Tolerant of partial pastes: if the user copies headers once but
//! not on subsequent pastes, or includes extra blank lines, the parser
//! still finds account blocks by the "Account number ending in" anchor.
//!
//! 6. The account number is extracted from "...NNN" at the end of the
//! account number line (the last whitespace-separated token).

//! Shared types and helpers for brokerage exports.
//!
//! This file holds the cross-broker shape — the normalized
//! `BrokeragePosition` record and the dollar-string parser every
//! broker needs. Per-broker parsers (`fidelity.zig`, `schwab.zig`)
//! build on top of these.
//!
//! ## Why not reuse `Lot` / `Account` from the portfolio model?
//!
//! Brokerage exports describe positions at a different granularity
//! and identity than zfin's portfolio file:
//!
//! - **Aggregate, not atomic.** A brokerage row says "100 AAPL @
//! $150 avg cost" — that single row can correspond to N lots
//! opened on different dates. `Lot` is per-buy; conflating them
//! would force a synthetic open_date every parser would have to
//! invent.
//! - **No buy date.** Positions CSVs don't include open_date /
//! open_price; you'd need a separate transactions export for
//! that. `Lot` requires both.
//! - **Current value lives on the row.** Brokerage rows carry
//! `current_value` as fact-from-the-export; lots compute value
//! from `shares × current_price` at query time.
//! - **Account identity differs.** Brokerage rows reference an
//! account *number* (the trailing N digits the export shows);
//! portfolio lots reference the human-readable account *name*.
//! The whole point of `accounts.srf` is to map between the two.
//!
//! `BrokeragePosition` is intentionally the unmapped, point-in-time
//! shape — exactly what the audit reconciler needs to compare
//! against the portfolio's mapped view.
//!
//! ## Memory & lifetime contract
//!
//! All string fields in records produced by the per-broker parsers
//! are slices INTO the caller's input bytes. The caller must keep
//! the input alive as long as it uses the returned records. The
//! returned slices themselves are heap-allocated against the caller's
//! allocator.

// ── Fidelity CSV parser ─────────────────────────────────────
//
// Limitations of this CSV parser:
//
// 1. NOT a general-purpose CSV parser. It handles the specific format
// exported by Fidelity's "Download Positions" feature.
//
// 2. Does NOT handle quoted fields containing commas. Fidelity's export
// does not quote fields with commas in practice (description fields
// use spaces, not commas), but a truly compliant RFC 4180 parser would
// need to handle "field,with,commas" as a single value.
//
// 3. Does NOT handle escaped quotes ("" inside quoted fields).
//
// 4. Does NOT handle multi-line values (newlines inside quoted fields).
//
// 5. Assumes UTF-8 with optional BOM (which Fidelity includes).
//
// 6. Stops parsing at the first blank line, which separates position data
// from the Fidelity legal disclaimer footer.
//
// 7. Hardcodes the expected column layout. If Fidelity changes the CSV
// format (adds/removes/reorders columns), this parser will break.
// The header row is validated to catch this.
//
// 8. Dollar values like "$1,234.56" and "+$1,234.56" are stripped of
// $, commas, and leading +/- signs. Negative values wrapped in
// parentheses are NOT handled (Fidelity uses -$X.XX format).
//
// 9. Money market rows (symbol ending in **) are treated as cash.
//
// For a production-grade CSV parser, consider a library that handles
// RFC 4180 fully (quoted fields, escaping, multi-line values).
