Change

• Reproduce Python rejection of valid signed JavaScript capsules with 2**53, 1e100, and Number.MAX_VALUE.
• Parse JSON integer tokens above the safe-integer range as binary64, matching JavaScript JSON.parse, then render tested finite numbers at JavaScript's fixed/exponent boundary. Reject non-finite results.
• Apply the same parser to saved HTTP exchanges and offline archive/migration verification. Add a signed case where a large attention budget participates in ledger arithmetic.
• Challenge a changed representable value and a non-finite token. Record the deliberate same-Number decimal alias (9007199254740992 vs 9007199254740993) and document that precision-critical identifiers and amounts need strings.
• Exercise large values through a real signed loopback HTTP response, archive, migration, and exact-byte recovery.

Local evidence

• npm test: 797 passed.
• 32 signed capsule scenarios and 28 cross-runtime HTTP scenarios passed.
• Archive, migration, shards, drill, repair, placement, API, upgrade, and Markdown link checks passed.
• Exploratory comparison of 249,885 finite number samples against JavaScript serialization found zero mismatches; this is a sample, not proof of complete equivalence.

Project-authored checks do not establish independent certification or production suitability.
