C1585–C1634 continuation evidence

This packet contains the source-bound continuation on the three inverse spines, from the C1584 predecessor to C1634. The readable report and printable explanation are in deliverables/. The 50 questions, results and reassessments are in journal.json and the readable continuation. The named source states and source hashes are retained in model/ and evidence/.

Verify the exact packet and complete cycle:

python3 verify_cycle.py --require-50

The verifier uses only the Python standard library and can run from another working directory by supplying the full script path. It reads the original source rows, recomputes the finite models, checks the journal chain and verifies every manifest payload. The arithmetic verifier was written independently of the construction code. Qualitative claim-selection ledgers are identified separately.

The PDF is supplied ready to read. Its optional reconstruction script requires Pandoc, XeLaTeX and the fonts specified in prep/render_readers.py; these are not dependencies of the arithmetic verification. The diagram asset is included.

This continuation synthesizes already supplied source information. It does not claim 50 independent discoveries, an unseen holdout result, a historical redaction sequence or statistical rarity. Deeper mirror analysis and second decimal reversal remain deferred.
