- core: asset tags (generated PREFIX-0001 or the human's own; unique ignoring case; never reused by another asset) and serial numbers (rules.md B-24); a journaled link from an asset to the entry that acquired it (posted, unreversed, debiting the cost account); fixed_asset_register(as_of), reconciled to the GL (unposted depreciation, unregistered cost)
- store: asset.tagged, asset.serial_set, asset.acquisition_linked journaled, replayed, projected (schema v9); differs_from now also compares control roles and tag history
- config: [books] asset_tag_prefix, default the company's initials without legal-form words
- import: Avery 5160/8160 label sheets with QR codes (geometry vendored from Avery, docs/spec/sources/avery-5160.md); the register as XLSX and PDF
- mcp: register_asset tags (and links) automatically; books.label_asset, books.asset_labels; asset tools take a tag; books.show asset / assets page / register report; export fixed_asset_register (json, csv, xlsx, pdf) and in the CPA package
- viewer: Assets page (register, reconciliation), asset page (identity, schedule posted vs not, entries, documents), Fixed asset register report, global search by tag/serial/description, journal text, needs-attention items
- fix: verify compared snapshot amounts as strings; a zero total summed in hash-map order could print "0" or "0.00", so agreeing books failed verify at random. Now by value (regression test)
- tests: spec-blind suites for tags, register, prefix, store, MCP; label and register PDF/XLSX tests; viewer tests

report_to_xlsx gains INVARIANTS 4-6 (header block, right-aligned amount
headings, spacer and account spacing, footer one empty row down, rules
exactly where rule_above says, exact text grouped in threes), tested by
reading the workbook's styles, merges and column widths. The general
ledger's footer now sits one empty row down like the other sheets.
Also killed: IIF transliteration arms, tax summary's optional sections,
and day-equals-month bank dates. `just mutants-import`, weekly in CI.

tests/spec_import.rs, written from the import crate's specs and sources
alone: every statement foots as printed on random books (P&L, balance
sheet with and without members, cash flow, trial balance, members'
equity), format_amount round-trips, bank CSV round-trips in both layouts
with date-order scenarios, IIF transactions sum to zero with every
account declared and ASCII fields, XLSX cells read back through a small
zip/DEFLATE reader, PDF labels with Typst markup render as text and the
bytes are deterministic, chart CSV and templates.
Its two findings, both fixed:
- "1/15/69" parsed as 2069: chrono's %y cuts over at 70, POSIX strptime
at 69 (69-99 are 1900s). Two-digit years are computed by POSIX now.
- An amount finer than a cent went into an XLSX as rounded text ("1.01"
for 1.005); it is written as its exact text now.

- Starter charts put "Platform and Payment Processing Fees" at 6100, the
code payroll posts wages to, so a template company that ran payroll
would book its wages as processing fees; their own payroll accounts
(7000, 7050, 2300) were never used. Now 6100 Salary & Wage Expense and
6110 Payroll Tax Expense (the engine's control accounts, with tax
categories), fees at 6060, and the unused accounts gone (the
withholding payables 2110-2150 are created when payroll first runs).
New tests: every template imports with categories valid for its
return; no template puts another account at a control code; a
partnership names every partner and its shares sum to 100%.
- format_amount printed a negative zero ("(0.00)" for -0.004); it rounds
half away from zero first now, like amount_parts.
- Specs (GOAL/SOURCE/INVARIANTS) for statement finishing, P&L, balance
sheet, cash flow, trial balance, members' equity (each must foot as
printed), format_amount, and the templates.
