CWQE Phase 10 (remainder): generation-side character framework + structure doctrine

[atomantic]

Summary

Second cohesive slice of the CWQE Phase 10 generation-side craft doctrine (#2175). Following the worldbuilding-doctrine slice (#2219), this ships the character framework and structure rules pillars — the doctrine autonovel's CRAFT.md injects before the writer drafts.

Character framework (generation + reconciliation).

• server/lib/storyBible.js — sanitizeCharacter gains the Ghost → Wound → Lie → Want → Need chain, a declared arcType enum (positive/negative/flat), the Three Sliders (sliders.{proactivity,likability,competence} 1–10, integer or null), and a secrets string list. All OPTIONAL — a pre-CWQE Phase 10: generation-side craft doctrine — worldbuilding laws, character framework (Wound/Lie/Want/Need + sliders), try-fail & beat rules #2175 record produces the empty/legacy shape (absent-vs-empty rule), so existing installs + federated peers round-trip unchanged. New BIBLE_LIMITS caps + CHARACTER_ARC_TYPES enum + ensureSlider/sanitizeCharacterSliders helpers. Fields added to PROMPT_FIELDS.CHARACTER and MERGE_CONFIG.character.userEditable.
• client/src/lib/bibleLimits.js — client mirror updated (enforced verbatim by the storyBible client-mirror test).
• client/src/components/universe/CharacterDetailEditor.jsx — a "Character framework" prose section (ghost/wound/lie/want/need), an "Arc type & sliders" section (enum <select> + three 1–10 range inputs with explicit unset/clear), and a "Secrets" list section. All fields wire htmlFor/id. secrets marshals string[]↔row objects at the section boundary.
• server/services/universeCharacterExpand.js — the AI-expand no-clobber merge fills the new prose/secret fields via the existing STRING/LIST loops, plus special-cased arcType (enum, fill-when-blank) and sliders (fill only the unset axes). Same source-of-truth field lists used by the vision-expand path.
• data.reference/prompts/stages/universe-character-expand.md — lean field guidance + output-contract keys, with the interlock checks (state the Lie in one sentence; the Need is its direct opposite; the Ghost causally explains the Lie) and the sliders rule (HIGH on ≥2, or one with growth; all-low = boring, all-high = Mary Sue).
• Reconciliation — canonCharacterTraitsSummary (checkInfra.js) now surfaces the authored Lie / Want / Need / arc-type, so character.consistency and the arc.* checks compare plan-vs-delivery instead of inferring the intended arc from the prose alone.

Structure rules at generation.

• pipeline-season-episodes.md — a "Structure rules" block: the try-fail mandate (60%+ of middle episodes end "Yes, but"/"No, and"), beat rules (Catalyst external; Break Into Two a protagonist choice; All Is Lost includes a death — literal or of a hope/relationship/identity), and climax = the protagonist's hardest ACTIVE choice between Want and Need.
• pipeline-arc-overview.md — MICE-style thread nesting (threads close in reverse order of opening; each season names the thread it opens and the thread it closes).

Migrations + drift. Shipped-template edits ship to existing installs via hash-keyed prompt-replace migrations 171 (universe-character-expand), 172 (season-episodes), 173 (arc-overview), each keyed on the OLD shipped md5 (line-ending-normalized). Prior owners of those files' current hash (003/005/019/027/166) are drift-cross-synced (old-current moved into ACCEPTED_OLD_MD5, NEW_SHIPPED_MD5 bumped) and the setup-data-drift.test.js baseline updated to match. Prompts kept lean — short imperative rules.

Test plan

• server/lib/storyBible.test.js — framework sanitizer round-trip WITH and WITHOUT the new fields; unknown arc-type / out-of-range / non-integer / numeric-string slider normalization; caps.
• server/services/universeCharacterExpand.test.js — updated field counts (21 strings + 6 lists); arcType/sliders no-clobber merge; framework prose + secrets fill.
• server/lib/editorial/checkRegistry.test.js — canonCharacterTraitsSummary surfaces authored framework fields; omits absent ones.
• client/.../CharacterDetailEditor.test.jsx — arc-type select, slider patch/clear, secrets string-list marshalling, framework prose fields.
• Migration 171/172/173 tests (standard runPromptMigrationTests suite) + resynced 003/005/019/027/166 drift-catch + setup-data-drift.test.js all pass.
• Full server suite (file backend): the only failures are the pre-existing environmental ones requiring live PostgreSQL/env stubs (dataRoot / backup / installState / mediaAssetIndex / runner / visionCli) — none touched by this change, identical set to CWQE Phase 10 (slice 1): worldbuilding craft doctrine — generation prompt + world.* editorial checks #2219.

Remaining work

Refs #2175 — NOT Closes. One Phase 10 item is deferred: the Le Guin style doctrine ("style is not ornament — it IS the fantasy"; prefer strong nouns/verbs over adjective-noun clichés) into the style-guide → prompt flow. The worldbuilding pillar (#2219) and now the character + structure pillars are done; the style-doctrine pillar remains on #2175.
