P3: assets' posted and scheduled depreciation, their bases, and the K-1 on the tax basis (defect 13, D-41)

Book value is cost less what the books posted; the schedule's figure is
apart. An asset's acquired date comes from its entry. Contributed
property keeps its section 723 carryover basis apart from its depreciable
basis (the lower of value and adjusted basis), with its 704(c) built-in
gain and method. The K-1 worksheet reports tax-basis capital (Form 1065
Item L) beside the book figures, leaving open what only the CPA knows.

 - **Current earnings** — Net income to date on an unclosed book. We fold it
   into equity so the accounting equation holds before close.
+- **Placed in service (in-service date)** — The day an asset is ready and
+  available for its use. Depreciation starts here (`Asset::in_service_date`;
+  journaled under its old name `purchase_date`).
+- **Acquired date** — The day the company got the asset: the date of the
+  entry that put it on the books (its purchase or a member's contribution),
+  never later than the in-service date. The register holds the asset from
+  here (`Ledger::asset_acquired_date`).
+- **Accumulated depreciation, posted and scheduled** — What the books carry
+  for an asset (its depreciation runs, less any reversed:
+  `Ledger::accumulated_posted`), and what its schedule says is due by a date
+  (`accumulated_depreciation`, `accumulated_scheduled_through` in the
+  tools). Book value is cost less the posted figure.
+- **§723 basis** — The company's tax basis in property a member contributed:
+  the member's adjusted basis at contribution (IRC §723).
+- **Adjusted basis** — Cost plus improvements, less depreciation allowed or
+  allowable (IRC §1016(a)).
+- **Depreciable basis** — What tax depreciation starts from: the cost for
+  something bought; the §723 basis for business property contributed; for
+  property contributed from personal use, the lesser of its fair market
+  value and the member's adjusted basis (Treas. Reg. §1.168(i)-4(b)).
+- **Built-in gain or loss (§704(c))** — Property's fair market value less
+  its §723 basis when contributed (Treas. Reg. §1.704-3(a)(3)(ii)). A
+  built-in loss counts only for the member who contributed it (IRC
+  §704(c)(1)(C)).
+- **§704(c) method** — How the tax items of contributed property are shared
+  among the members so the built-in gain or loss stays with its
+  contributor: traditional, traditional with curative allocations, or
+  remedial (Treas. Reg. §1.704-3(b)-(d)), chosen property by property.
+- **Tax-basis capital** — A member's capital account as Schedule K-1 Item L
+  reports it: cash plus the adjusted tax basis of property contributed,
+  plus their share of income as figured for tax, less cash and the adjusted
+  tax basis of property distributed (Form 1065 instructions, Item L).
