siddharthd	c465742635	docs: capture this session's learnings for a future pickup ... CLAUDE.md gains the traps a new session would otherwise re-discover: - Rules: a zero-condition rule matches everything (rule 43 would split all ~3,700 transactions); preview-then-apply-by-id is the safe pattern and why it beats auto-applying on ingestion; how run provenance works. - Shared expenses: transaction_splits.settled is dead data; getParticipantBalances is correct and must not be 'fixed'; settlement cannot be attributed per trip. - The shared loan: separate ledger, fixed 50% with a tracked receivable, why the share must not be derived from actual payments, and why interest stays as spend. - Extraction: balance assertions are the check that works, do not derive opening_balance or add a totals assertion (both would be tautological), Gemini invents summary fields it was not given, empty statements must not throw, FX is per-date, and CSV comparisons need millisecond ordering. The design doc records Phase 0 as done - including that the original Phase 0 plan was wrong, since reading the code first is what prevented breaking a working balance page. Known Gaps lists what is open: the unbuilt phases, 11 failing assertions, the uncategorised Up rows, and the CSVs sitting in 030490e's history.	2026-07-26 16:19:02 +10:00
siddharthd	ba87ff86e7	docs: record loan decisions — separate ledger, 50/50 fixed, $4,000 receivable ... The loan is a separate ledger, not a settlement context: a contribution must never be able to settle a dinner. The share is fixed at 50%, not derived from actual payments. During Sonu's leave the obligation did not change, only the payment did - a percentage-of-actual model would silently redefine her share as 30% and make the shortfall vanish. So the model needs an expected schedule alongside actual contributions, with the difference as a tracked receivable. Currently $4,000.00 over Jul 2025 - Jun 2026. On interest: recorded the mechanics (it is debited to the loan and repaid as part of the balance - the reconciliation is exact) alongside the counter-argument that $16,523.64 left and bought nothing, which is what an expense is. Recommends keeping it as spend with a fixed/discretionary grouping to address the real concern, but flags it as a judgement call rather than settling it.	2026-07-26 16:03:53 +10:00
siddharthd	4b7a7e5d9c	docs: design proposal for shared expenses, settlement and the shared loan ... Three problems that look separate are one: the app records money moving, and separately records who owes whom, and the two never meet. Documents what is broken with evidence - two half-built settlement models, settlements existing twice unlinked, and Sonu's $37,980 of loan contributions sitting unrecognised as generic transfers - then proposes settlement contexts, payments as transactions rather than a side table, and loan co-ownership. Nothing built. Five open questions, two of which are decisions about the arrangement rather than the software.	2026-07-26 15:57:03 +10:00
