v0.3.0 — The first astronomical ChronologyProof (2026-08-21)

Sandwich v2: a real optical observation of the sky, inside the causal bounds. On
the evening of 2026-08-20 the operator photographed the gibbous Moon over New Delhi
with a fresh challenge code — the first 16 hex digits of q, derived from block 252's
hash five minutes earlier — handwritten on paper inside the frames. Ten original
frames (EXIF intact, sha256-manifested) became a CAMERA-PHOTO/v1 witness beside
five fresh NTP witnesses in the epoch-2 checkpoint, chained to epochs 1 and 0, mined
into height 253 (parent = B0: an adjacent-block causal window again) and buried by
ten overnight laboratory blocks.

verdict  SANDWICH_PASS — all checks, incl. S_CAMERA_BINDING and S_PHOTO_FILES

The bundle carries the open-astrolabe engine's expectation for the capture instant —
Moon at SW 216.6°, altitude 24.0°, 55.2% illuminated, reference grade — as
prediction_json, labeled EXPECTATION_NOT_EVIDENCE. The frames show exactly that.
The prediction-vs-photo comparison is human-verifiable by design in this profile;
a plate-solved astrometric residual is named future work, not claimed. Full record:

normative profile: docs/REALITY-SANDWICH.md §6. Suite: 27 tests.
