 - **Numbering:** received as "CR-024 — Random Events, Radio Calls, and Hull Condition" for "Phase 24"; stored as **CR-026**, built as **Phase 26** (its 24.n = 26.n), since CR-024 (Fleet Sleep) and CR-025 (Short Away Summary) exist. Its decisions CR-024.D1–D9 are **0.5.143–0.5.151**. Its references: CR-005 → CR-007, CR-006 → CR-009, CR-011 → CR-014, CR-014 → CR-015, CR-015 → CR-016, CR-018 → CR-019, CR-019 → CR-021, CR-021 → CR-023, CR-022 → CR-024, CR-023 → CR-025; CR-001, CR-004 and plan Steps 3.13, 3.17 and 12 are unchanged.
 - **"HQ" is the Bridge**, as in CR-021, CR-024 and CR-025.
 - **The catalog has 14 events**: nine bad or neutral and five good, as the CR's tables list them.
+
+## Step 26.1
+
+- **Places get a region** (inner, belt, jupiter), so event conditions read from content: a leg between regions crosses or enters the belt; Earth↔Moon and legs inside the Jupiter system are the "local loop"; legs with an end in the inner system or belt can meet spot freight.
+- **Events whose effects are a share of the payout need a contract**: the derelict pod, distress beacon, spot freight and customs hold, as well as the grateful client. On a deadhead they would be worth nothing.
+- **An option is "always" effects plus exclusive chances**: push through the debris field is 35% hull damage, 10% lost pay, otherwise nothing; seal the hazmat leak is +2 h always and 30% hull damage.
+- **Weights:** bad 70 (flare 10, micrometeor 8, hiccup 10, debris 10, storm 8, customs 8, hazmat 6, load shift 6, spoilage 4), good 36 (tailwind 10, grateful client 10, pod 6, beacon 4, spot freight 6): 34% good. Step 26.9 tunes them against the balance targets.
+- **Hull Plating adds a flat +1 a level** (`flatPerLevel`), since a percent of a rating of 1–3 would be fractions; its cost and shop time follow the usual upgrade levels.

+- [x] **Step 26.1 — Content.** `content.tripEvents` (`packages/content/src/data/events.ts`, `tripEventSchema`): the 14 events of CR-026 §3, each with kind (automatic or radio), good flag, weight, title, text, when it can happen (trip length, belt crossings, inner/belt legs, arrival regions or places, contracts, cargo class with skill halving, Priority perishables, a hull-below weight factor) and options (label, default, effects, exclusive chances, free hold or fuel needed). Config `events` (pacing, decision 0.5.145) and `hull` (decision 0.5.148). Every location has a `region` (inner, belt, jupiter). Hull Plating (`hull-plating`, +1 hull rating a level, three levels): upgrades can now add a flat amount (`flatPerLevel`), and `hullRating` is an upgradable stat. Tests: `packages/content/test/events.test.ts` (the 14 valid events; one default per radio call, and two refused; chances at most 100%, and over refused; good weight 34%, within 28–38%; ids that exist; the config numbers and regions; Hull Plating); `packages/sim/test/effective-stats.test.ts` (Hull Plating adds 1 a level).
