docs: create evidence-backed judge journey

[moneyparking]

Decision

Replace the stale two-line public presentation with a reproducible judge journey and truthful evidence ledger.

Deliverables

• product/value and load-bearing-memory README
• five-minute judge guide
• current acceptance evidence ledger
• 2–5 minute recording script
• corrected build status with explicit open gates

Verification

• exact-head PR CI: run 33533238376 — success
• head commit: 68ae1c51778136555aa07ff0ce4196f31b95097f
• real sibyl-memory-client==0.8.0
• 11 passed in 0.99s
• separate-process A/B/C acceptance: AUTHORIZED → AUTHORIZED → INVALIDATED
• memory-unavailable fail-closed acceptance: BLOCKED / AUTHORITY_MEMORY_UNAVAILABLE / governed_action_executed=false
• physical Sibyl deletion: UNRUN (explicitly recorded; not claimed by the current script)
• independent re-review: no Critical or Important findings; ready to merge

Scope

Documentation only. No authority semantics, SDK contract, or runtime behavior changed. The incomplete MIT license text is recorded as a separate open compliance gate and is not silently claimed complete.
