Parity catalog

Every semantic feature we intend to clone, with its status. Updated in the same commit as the feature. The floor never decreases: the count of done items is monotonic across commits.

Statuses: done = implemented + invariant-tested + golden-covered. partial = implemented but missing tests or goldens. todo = not started. No other statuses.

Floor: 10 done (2026-10-10; fixed-asset register added).

Balance sheet as of a date, line per account Reports → Balance Sheet (as of) partial hand-verified fixture + property tests; no golden file yet
General ledger by account (running balance, split) Reports → General Ledger partial hand-verified fixture, ties to trial balance; no golden file yet

Reversing entries Reverse transaction done linked via reversal_of
Canonical report snapshots (JSON) — (our oracle format) done reports::snapshot
Fixed-asset register + straight-line depreciation Fixed Asset register done assets.rs; golden-covered schedule; idempotent runs; disposal with gain/loss; posted (the books') vs scheduled, in-service vs acquired dates, the §723, depreciable and §704(c) figures (P3)

Tracking classes (divisional P&L) Class tracking done invoice and bill lines take a class too (projects, rules.md B-37 item 8; QBO/Xero class or tracking per line)

Automated cross-implementation diff harness (GnuCash first) — (our xtask oracle) todo roadmap phase 3

Workflow/UI parity (QuickBooks/Xero reference) gets its own catalog when the egui phase starts; semantics come first.

P0 guard rails (2026-10-16)

P0 (plan/served.md) changed no feature in the catalog above, so no status moved and the floor stands. It hardened what exists: an older version refuses books from a newer one as newer, not corrupt (rules.md B-27); the MCP server fails closed after an internal error, and no input reaches one (dates are four-digit years, amounts at most a line's, B-28); local files were read only from the import roots, never the books, the vault or its key (P2 slice 5 removed local paths: files now come in only as uploads, D-46); no file with a full TIN is filed into the books (B-26); the agent is told the rules in force in a short connect text and a handbook, and no agent text points at the books' files, git or the repo.

U0b: one attention engine (D-53, 2026-10-26)

No semantic feature changed, so no status moved and the floor stands (10 done). Needs attention used to be computed by the viewer alone; it now lives in ledger-package::attention, over PackageBooks, and both the viewer and books.start read it (the same items, the same prompts), so the list the human sees and the next steps the agent gets cannot drift. The parity test the_viewer_and_books_start_see_the_same_attention compares them item for item on the demo books and on a book written entry by entry.

Capability parity (AI-first phase)

Semantic parity (above) is about correctness: the engine computes the right numbers. Capability parity is about usefulness: can the new system do everything the GSheet+GDrive system does today? Tracked separately in docs/capability-parity.md, with its own cutover rule (parallel run + the owner's approval). The two catalogs converge: when both are green, the sheet retires.

P13 bookspec (2026-10-26)

P13 is a specification, not a feature, so no row of the semantic catalog moves and the floor stands. It adds the checker crate (bookspec/checker: the example schema, the rule identifiers BS-<area>-<n> and the Engine trait), the runner (bookspec/runner: pass, fail or not claimed per rule), and the rule index from B-1 to B-45 (bookspec/spec/rules-index.md). Every existing bookspec example still runs on every cargo test, through both the loader's own checks and the Engine trait.

P6: the evidence pipeline (2026-10-26–27)

No semantic feature of the catalog above moved, so no status changed and the floor stands (10 done): P6 changes how evidence is kept, not how a figure is computed. It adds one in-process extractor (a PDF's text and pages, an XLSX's cells as exact decimal strings, plain text; 25 MiB, 30 pages, 2 MiB of text), journals each extraction as its own record (one per attachment, extractor and version, its text a content-addressed blob whose hash books.verify checks), holds identical bytes as one live attachment (linked to every subject, legacy duplicates consolidated with duplicate_of), records what a human read off a file (the closed annotation field list, engine receipt numbers running from the max) and what a payment settles (entry.settles, the only source of "reimbursed"), and gives company records four more homes (notices, correspondence, plans, history, D-20). Rules.md B-44 states it; docs/testing.md's P6 section lists its tests and the P12 mutation targets.
