whatif: live data refresh, inflation-adjusted spending, legend fix 
Three follow-ups to the actualbudget integration:

**Always-fresh autofill.** Drop the one-shot `*AutoFilled` boolean
gates; replace with `nwUserEdited` / `spendingUserEdited` flags. Until
the user types into either field, every refetch (mount, window
focus) updates the form value. Once they edit, we leave it alone. A
small ↻ button next to each anchor input flips the edited flag back
off so the user can re-snap to live data on demand. React Query
configured with staleTime=0 + refetchOnMount='always' +
refetchOnWindowFocus=true so the cache never serves stale numbers.
NW provenance shows the snapshot date.

**Inflation-adjusted spending.** Backend now revalues each trailing
month's nominal pence forward to today's £ using monthly compounding
of `inflation_pct` (default 0.03 ≈ UK CPI 2024-26). Headline
`total_gbp` is the real-£ figure — matches the simulator's
real-GBP convention. Response also includes `nominal_total_gbp` and
`inflation_pct` for transparency. New /spending/annual?inflation_pct=
override param. 10/10 actualbudget tests pass.

**FanChart legend.** The bottom-anchored legend was overlapping the
x-axis label. Moved to top: 8 with itemGap=18 + type=scroll for
narrow viewports; bumped grid top→48 / bottom→56 + xAxis nameGap→28
so nothing collides.

fire-planner

Risk-adjusted, tax-minimised FIRE retirement planner. Consumes today's portfolio, savings rate, and RSU vest schedule from sibling services (wealthfolio, payslip-ingest, hmrc-sync) and returns the after-tax probability of success for each combination of jurisdiction, withdrawal strategy, and "year you break UK tax residency".

Layout

  • fire_planner/ — package
    • tax/ — per-jurisdiction tax engines (UK, nomad, Malaysia, Thailand, Cyprus, Bulgaria)
    • returns/ — Shiller 1871+ data + block bootstrap sampler
    • strategies/ — Trinity 4% SWR, Guyton-Klinger guardrails, VPW
    • ingest/ — pulls from wealthfolio / payslip-ingest / hmrc-sync
    • simulator.py — vectorised NumPy MC engine
    • scenarios.py — Cartesian product over (jurisdiction × strategy × leave-UK-year × glide)
    • app.py — FastAPI on-demand /recompute
    • __main__.py — click CLI: ingest, simulate, recompute-all, migrate

Common commands

poetry install
pytest -v
mypy .
ruff check .
yapf --recursive .

Schema

Six tables in fire_planner schema on pg-cluster-rw:

  • account_snapshot — daily NW per account (Wealthfolio)
  • scenario — Cartesian-product scenario definition
  • mc_run — execution metadata + summary stats per (scenario, run_at)
  • mc_path — sparse storage (top decile, bottom decile, median)
  • projection_yearly — deterministic point projection per scenario
  • scenario_summary — denormalised fast-read for Grafana
