Backtest result card and saved-run history now show an explicit dividend
badge per run: green 'ตามวันจริง' for dated_ledger (real ex-date x qty cash
flow), amber 'Proxy (ต่อหุ้น)'/'Proxy' for estimates, plus a footnote that
matches the actual dividend_method. Frontend build passes (bundle
index-DDItjwYy.js); served bundle contains the new strings.
Forward mode in the simulation tab now calls the durable /api/v1/forward
lifecycle instead of the single-pass /api/v1/simulation (which only differed
by a mode string). runSimulation branches to /api/v1/forward for forward mode,
loads runs on mount, and renders a forward panel listing each paper run with
its status (frozen/executed/marked/matured), non-PIT badge, holdings and a
Mark / Mature action per run. Frontend build passes (bundle index-INuvPOCF.js).
Map dividend_method (dated_ledger / dps_annual_proxy / final_holdings_yield
_proxy) to an honest Thai label. Show a Proxy badge whenever the dividend is
an estimate (everything but dated_ledger) on both the result card and the
saved-run history rows, and set the footnote to match the actual method.
Frontend build passes.
- P1: /api/v1/simulation now uses the canonical board score (default_scores)
instead of a divergent 3-theme recompute -> 'จำลอง' can't disagree with board
(live check: sim top pick PTT == top board combined 1.600). Removes binary
auto/en signs, restores quality+momentum+dividend screen consistency.
- P2: dashboard emits source_summary{factor_keys, rows}; frontend shows
'N ปัจจัย · M แหล่ง' so the 7-vs-5 count confusion is impossible.
- P5: removed dead themes.list_themes()/Theme/build_theme_scores/_map_index and
the tests that locked them; added tests/conftest.py so pytest needs no PYTHONPATH.
- docs: audit-and-plan-2026-08-26.md (full P0-P5 plan) + engineering-log entry.
- 203 backend tests pass; Vite build passes. Independent reviewer: no security or
logic blockers (minor error-leak suggestion applied: 503 message no longer leaks
exception detail).
- backtest.py: buy-and-hold backtest over [start,end] — allocates 50/20/30 at first available rebalance date, marks to market to end, accrues dividend, reports {final_value, price_pnl, dividend_income, net_return, trades, holdings}
- Fixed double-spend bug (was allocating full capital every rebalance -> negative cash)
- dashboard.default_scores(): per-symbol combined/dividend/yield baseline for backtest
- POST /api/v1/backtest + GET /api/v1/backtest/runs (results persisted in app state -> survive refresh)
- Frontend: backtest section w/ start/end/capital/freq inputs + P&L KPIs + run history table
- Honest note: uses current combined scores as static baseline (non-PIT); PIT score_fn pluggable
- Verified: 1M -> 1.088M (+8.80%) over 2024-06..2026-06; history persists across refresh
- THEME_SYMBOLS expanded: added banks, retail, telecom_it, property, healthcare, petrochem_materials, consumer_staples, utilities, nonbank_finance, exploration -> all 49 SET50 names now in a theme
- THEME_LABELS_TH Thai labels; THEME_FREQUENCY per theme
- symbol_breakdown now lists EVERY theme the symbol belongs to (label_th + surprise, or 'ยังไม่มีข้อมูล'), so theme_score is transparent per source
- frontend: theme column maps all 49 symbols (mirrors backend); modal shows per-theme score detail
- Fixed test for BANPU multi-theme; full suite 199 OK
- Verified: 49/49 rows have theme chip; AOT modal shows ท่องเที่ยว 0.57σ + full calc
- Theme panel (ธีม): shows tourism/auto_credit/refining_energy with Thai labels, frequency chips (monthly/quarterly), and real factor reads (tourism surprise, car sales YoY, TOP net profit) from /api/v1/themes
- Combined count badge; responsive 1-col on mobile
- Loads /api/v1/themes in loadDashboard (already wired backend)
- Verified: npm build passes, browser shows 3 Thai cards with live values
