The cash flow statement was computed and exportable as csv/json/xlsx but
missing from every PDF path, so the CPA package carried two of the three
financial statements. Now:
- ledger-import: cash_flow_pdf renders the indirect-method statement
(operating with net income, depreciation add-back, working-capital
lines; investing; financing; net change reconciled to beginning and
ending cash) from the computed CashFlowStatement, so the period and
cash accounts are the caller's.
- books.export gains format "pdf" for profit_and_loss, balance_sheet, and
cash_flow (base64, like xlsx), plus financing_accounts for cash_flow.
- books.export_cpa_package adds cash-flow.pdf (fiscal year to date, like
the P&L) and requires cash_accounts: without them the statement has
nothing to reconcile to.
- One cash_flow_statement helper resolves codes and dates for xlsx, pdf,
and the package.
Test: MCP stdio test exports all three statement PDFs, checks the
cash_accounts and bad-report refusals, and unzips the CPA package to find
all five files. Known report gaps are logged in plan/STATUS.md.

Posted entries stay immutable (R-3), but their evidence can now change the
same way the ledger does: by appending events, never by editing or
deleting. New R-13a.
- books.unlink_receipt {attachment_id, reason} journals receipt.unlinked
and leaves the receipt filed, unlinked. The receipt policy holds: an
entry that requires a receipt can't lose its last one (structured
receipt_required error), so a replacement is attach-new, then
unlink-old. Drafts and reversals are exempt, as at posting.
- books.withdraw_attachment {attachment_id, reason} journals
attachment.withdrawn for an unlinked receipt or a filed document: hidden
from list_receipts (unless include_withdrawn), never linkable again. The
blob stays in the store, hash-verified and readable.
- link_receipt now refuses an already-linked or withdrawn attachment.
Before, re-linking silently moved a receipt off a posted entry,
bypassing the policy; evidence now leaves an entry only through a
recorded unlink. dispose_asset checks its receipt ids before posting
instead of after.
- Schema v5 adds attachments.withdrawn_at/withdrawn_reason; existing
stores migrate on open and replay rebuilds the projection.
Tests: store test (errors, reopen, rebuild, verify, journal history) and
an MCP stdio test (policy refusal, replace flow, withdraw, listings,
under-threshold unlink). Dry-run and live use on the Wanderland Labs books:
8 migrated .eml attachments swapped for their PDF renders, trial balance
unchanged.
