Cross-issue prose continuity: inject prior issue's prose tail + next issue's beats into the prose stage

 - **[issue-2175] Worldbuilding craft doctrine now shapes universe generation up-front, and two new editorial checks verify it.** The universe-expansion prompt now injects Sanderson's-Laws craft doctrine before the writer model drafts — limitations over powers, costs that drive plot decisions, solutions foreshadowed before they resolve, iceberg depth, interconnected systems, 2–3 societal implications per major system, and a sensory signature per location — so autonomous and interactive runs alike start from a lived-in world instead of decorative set dressing (Series Autopilot calls the same stages, so autonomous mode is upgraded automatically). Two new series-scope editorial checks close the loop on the review side: `world.unforeshadowed-solution` (a plot problem solved by a rule/power the reader was never shown — the worldbuilding sibling of the deus ex machina) and `world.cost-free-power` (an ability used at a decisive moment with no cost or limitation on the page). Both reconcile the prose against the established world canon and the continuity-bible world-rule facts, so a rule that WAS planted earlier is not flagged. (First slice of #2175 — the character-framework and structure-rule pillars ship separately.)
 - **[issue-2179] A series style guide can now carry concrete voice exemplar and anti-exemplar passages — "the tuning fork" — that get injected into every draft and revision prompt.** Adjective lists ("witty, atmospheric") anchor prose voice far more weakly than an actual passage does, so the series style guide gains two new fields: `voiceExemplars` (1–3 short passages that nail the target voice, each with an optional one-line note on what it demonstrates) and `voiceAntiExemplars` (passages in the wrong register kept as negative examples, noted with what's wrong — "too ornate", "wrong emotional temperature"). Add and edit them inline on the series style-guide editor. On generation they render into the house-style block as a "MATCH this voice — echo their rhythm, diction, and register" block and a "NEVER drift toward this" block — conditional, so a guide with no passages injects nothing. They ride the existing `{{series.styleNotes}}` template variable (via `composeStyleNotes`), so prose drafting, revision, arc planning, and episode-seed passes all honor them with no new prompt-template variable and no migration. The sanitizer drops empty passages, trims each to ~2000 chars, and caps the list at 3 so the fixed per-call prompt overhead stays tight. (First slice of #2179 — the AI-assisted voice-discovery flow, Writers Room parity, and the voice-fingerprint baseline hook ship separately.)
 - **[issue-2178] Canon can now be reveal-gated so a mystery or twist doesn't leak into the prose before it's due.** Canon context — including character secrets and late-story facts — was injected into every issue's drafting prompt, so the writer model could (and would) spill a reveal issues early. Each canon entry (character, place, or object) now carries optional reveal gating: a `revealIssue` number hides the fact from any issue before it; a `spoiler` flag hard-hides it from all drafting context; and an optional `surfaceDescriptor` is the spoiler-free stand-in shown before the reveal ("the locked east wing" instead of "the wing where the heir is imprisoned"). The drafting/rewrite prompts (`buildStageContext`, the alternate-POV rewrite cast) filter canon to each issue's reveal horizon, while the judge and editorial checks still receive the full canon so they can verify hint placement. Absent gate fields mean "always visible," so every existing canon entry and every federation peer round-trips unchanged. A reveal-timing editor with a spoiler badge lands on every canon-entry card (universe + series). A new `continuity.premature-reveal` editorial check (gated on the series having authored any reveal-gated canon) scans drafted prose for a gated fact stated or unambiguously implied before its reveal issue, distinguishing a genuine leak from deliberate foreshadowing — and its reveal issue feeds the Chekhov setups-payoffs check as an authored payoff so an orphaned reveal is flagged too.
+- **[issue-2177] Prose drafts now flow across issue boundaries instead of each issue opening and closing in a vacuum.** When drafting an issue's prose, the generator now injects the previous issue's actual closing prose (its last ~2000 characters) and the next issue's opening beats into the draft prompt — with guidance to open so it flows from the previous ending (without repeating its closing image or re-explaining what the reader just read) and to land the ending so it hands off to the next issue's beats. This is what keeps the narrative voice carrying across units and prevents the "every issue opens/closes the same way" tic, improving the autonomous first draft so the editorial loop has less to fix. Both blocks are token-budgeted (they degrade by trimming on a small-context local model rather than erroring), and when the previous issue hasn't been drafted yet — non-linear or parallel generation, or the first issue of a volume — the block simply doesn't render, so there's never any fabricated continuity. Every full prose (re)generation path gets it: the manual draft button, the auto-runner, and Series Autopilot. Existing installs auto-upgrade their prose prompt (a customized prompt is left untouched and flagged).
