v0.27: cross-reference cleanup of event-zones.md across domain papers

Closes the v0.26 interaction-substrate paper-pass cycle initiated 2026-04-27
via the plan-as-baton mechanism (EVENT_ZONES_FOLLOWUP_PLAN.md authored at
end-of-context-density, mechanical execution next-session, scaffold deleted
on completion per the v0.24.5 pattern).

Substantive (political-register/world-generation.md → v0.2):

- §Editor-mode pre-flagging (extends L4 Cell ruleset, v0.27): editor_eligible
  bool field per cell, pre-flagged at world-gen-init; designer-tunable defaults
  per district-tier (deva-pinnacle 0% → underground/wilds 90%); per-cell
  carve-cost gradient scales by cell-position-imperialness. Choice (a)
  designer-flag-at-world-gen committed over choice (b) emergent-from-imperial-
  scrutiny per the 2026-04-27 dialog: clean LOD signal + political-readability
  via material-vocabulary + zero runtime audit-overseer-presence checks.

- §Three-source schema unification (v0.27): cell_table accepts canon-rows
  from world_gen_init / runtime_event / player_authored origins via shared
  schema. The architecture's world-gen-as-init-function key-move now extends
  to player-edit-time as a first-class peer of generator-output and runtime-
  emission. Cell-checksum-divergence audit-vector gains a third source
  (player_authored_divergence) consumed by the same Memorialist counter-
  archive and GM heresy-detection mechanisms.

Mechanical cross-references (single-paragraph propagations of v0.26 design-
decisions through the architecture's describe-by-cross-reference discipline):

- runtime-engine/architecture.md: event-zones.md added to Companion-to header
- style/consent-discipline.md: §Variants 1-4 as event-class taxonomy — the
  four hardstop-pattern variants correspond one-to-one to the event-class
  taxonomy in event-zones.md; the register-test five-question procedure is
  also the event-class-classifier (consent-validation = event-instantiation)
- style/trait-palette.md: 8 traits compose onto the cosmology's outer ring —
  vertically-symmetric on Deva (Sophrosyne+Dikaiosyne) and Naraka (Eros+Philotes),
  side-castes carrying single traits, all four oppositional pairs preserved
  at 180°. Composed wheel renders as iconography AND UI substrate
- narrative-composition/architecture.md: Three-source schema unification
  extends world-gen-as-init-function to player-edit-time
- inference-and-memory/architecture.md: Compositor reads 2D gesture-history
  (caste-target × trait-temperature); coherence-of-political-positioning
  becomes a cornerstone-memory salience axis
- identity-and-personhood/architecture.md + bodies.md: install / clasp /
  post-rogue-NPC-modding mini-games all run on the composed wheel; consent-
  discipline Variants 1-4 determine participant-count and hardstop-pattern;
  the wheel renders the resolution

Verification: 11 papers now reference event-zones.md (vs 4 pre-v0.27,
including the bonus pre-existing imperial-narrative.md cross-ref). The
describe-by-cross-reference, not by re-quotation discipline reaches steady-
state across the corpus. Cross-references resolve cleanly to existing
sections in event-zones.md (verified §Variants 1-4, §The wheel, §Player
editor-mode, §Hardstops, §The composition).

The Compositor reads this 2D coordinate over time as the player's *political-position-history*: which caste-tiers the player has been addressing AND with what trait-temperature. Memory-class assignment (cornerstone / birthright / working / volatile per the existing memory-class hierarchy above) gains a new salience axis: gestures that consistently target one caste-tier with one trait-temperature accumulate as cornerstone-memory faster than scattered gestures. *Coherence-of-political-positioning becomes a memory-elevating signal in its own right.*

 `clasp.sqlite` is the **architectural floor of the rings-of-data-sharing**. Ring A was "opt-out (default local)". Clasp is **Ring A\***: *no transport path exists*. Not a permission, not a TOS promise — there is no code that can move this data, because the table is not on the sync graph. Lawyers cannot subpoena what doesn't ascend; engineers cannot leak what has no socket; the GM cannot canonicalize what it never received.
