feat(ring-46): E2E CI loop — Closes #150

[gHashTag]

Summary

Closes #150 — Demonstrates E2E CI loop: seed.t27 → t27c gen → zig test → GREEN

Changes

1. specs/base/seed.t27 — Minimal golden seed spec

   • Type definition: Trit enum with neg, zero, pos
   • Functions: trit_negate(), trit_add()
   • 5 tests covering basic operations
   • 2 invariants: trit_value_range, trit_negate_involutive
   • SOUL.md compliant (ASCII-only, has .test section)

2. bootstrap/src/compiler.rs — Fix Zig codegen

   • Changed return type syntax from -> to space (Zig uses fn foo() T, not fn foo() -> T)
   • Line 2809: self.write(&format!(" {}", return_type));

3. .github/workflows/phi-loop-ci.yml — Add E2E CI step

   • Added push: branches: [master] trigger
   • Added Zig 0.13.0 installation
   • Added E2E test step: generates Zig from seed.t27 and runs zig test

4. .trinity/seals/*.json — Regenerated all 57 seals after codegen fix

5. docs/NOW.md — Updated §3.2

   • E2E status changed from "not yet proven" to "DEMONSTRATED"
   • TV-01/TV-02 marked as PASS
   • Spec count updated: 57 files

6. docs/qualification/TVP.md — Updated §3

   • TV-01: ✅ PASS — 57/57 specs, 0 failures
   • TV-02: ✅ PASS — all 57 seals current

7. .trinity/experience/clara_track1.jsonl — Added Ring 46 E2E CI entry

Verification

• ✅ ./scripts/tri test — All 57 specs pass
• ✅ ./scripts/tri check-now — NOW gate passes
• ✅ zig test gen/zig/seed_e2e_test.zig — All 5 tests pass
• ✅ All 57 seals regenerated and verified

Acceptance Criteria (from plan)

• Phase 1: CI failure diagnosed
• Phase 2: seed.t27 exists with .test section
• Phase 3: t27c gen succeeds locally
• Phase 4: zig test passes locally
• Phase 5: phi-loop-ci.yml updated with Zig + E2E step
• Phase 6: Existing failures fixed (seals regenerated)
• Phase 7: NOW.md + TVP.md updated
• Phase 8: PR created with Closes E2E CI: seed.t27 → t27c gen → zig test → GREEN #150
