New file internal/plugin/expedition_balance.go — sibling to dnd_class_balance.go, no dnd_ prefix per feedback_avoid_dnd_naming. Plan doc: gogobee_expedition_difficulty.md. Critical de-risk settled: clock-injection seam. The harness does not run the wall-clock tickers (expeditionBriefingTicker @ 06:00, expeditionRecapTicker @ 21:00, expedition_ambient @ 3h) and does not inject a virtual time.Now. Instead, advanceExpeditionOneDay reimplements the morning→day→night pipeline by calling the math-pure helpers directly: applyDailyBurn, dailyThreatDrift, resolveCombatInterrupt, resolveWanderingCheck, simulateCombatWithRNG. No DB, no goroutines, no clock. Phase 0 trade-offs (documented in the file header): - Boss completion deferred; survive-N-days is the proxy. - Per-region zones, loot/XP, pardon/Sovereign, babysit, temporal stack effects all skipped — Phase 1+ scope. - Encounter cadence (harnessHarvestRollsPerDay=4) is a placeholder to be calibrated against live traces in Phase 1. Tests: - TestExpeditionBalance_Phase0_Spike — T2 Crypt Valdris × L5 Fighter, 100 trials, asserts only degenerate sentinels (no 0%/100%, days>0, days<=cap). Runs in <3s. - TestExpeditionBalance_Phase0_SeedSpread — confirms the RNG seam is actually wired by showing two distinct seeds produce different trials. Full byte-for-byte reproducibility under same seed is not asserted at Phase 0; surpriseRoundNick + pickWanderingMonster draw from package-global rand (same caveat as class balance). Spike numbers (calibration baseline, NOT a target): 1% completion, 99% deaths, median 4 days, ~6 encounters. The headline death rate is loud but expected — Phase 1's full matrix will diagnose whether it's HP-carryover punishment, bestiary-vs-abstract-monster delta, or kit ladder mismatch. Phase 2 is where the centerline gets tuned. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

// trials, sensible numbers, fully deterministic from the seed.
|
||
//
|
||
// The cell — T2 zone (Crypt Valdris) × L5 Fighter — was chosen
|
||
// because it's the smallest cell that actually exercises every part
|
||
// of the seam: tier scaling raises monster AC/atk, supply burn lands
|
||
// at 1.5×, the player is built off the class-balance loadout ladder
|
||
// at the T2/+1 step, and the night phase has roster entries to draw
|
||
// from. If the seam works here, Phase 1's full-matrix expansion is
|
||
// mostly typing.
|
||
//
|
||
// Pass criteria are intentionally loose — we are not asserting a
|
||
// target band yet (Phase 2 does that), only that nothing is wired up
|
||
// so badly the result is degenerate (0%/100%/NaN/zero days). Anything
|
||
// in (0..100%) completion at this cell is a green Phase 0.
