CALL NUMBER: deep_commit_object.commit_message_encoding_transcoding_logic
DEFINITION: git's internal conversion from the stored encoding_value to the requested log_encoding_flag encoding; uses iconv-style conversion with loss handling.
Invoke this skill to understand commit_message_encoding_transcoding_logic down to its primitives. The RELATIVE ROOT below is the least-fixed-point closure of everything it bundles from — the full import cone, grouped by the lib each prim comes from. Projected from a prover-typed KB (MAP/SWI-Prolog consistency gate): every reference below resolves.
THE RELATIVE ROOT (the import cone, by lib)
from deep_commit_object
- commit_message_encoding_encoding_fallback (d1): Fallback behavior when transcoding_logic cannot map a character; typically replaces with a substitution character or skips the byte.
- commit_message_encoding_transcoded_message (d1): The output of transcoding_logic: message_bytes decoded then re-encoded into log_encoding_flag; git log emits this to the terminal.
- commit_message_encoding_display_encoding (d2): The terminal or output stream encoding git uses when writing the transcoded_message; git assumes UTF-8 output if terminal encoding is unset.
CONSUMERS (what needs this)
commit_message_encoding_encoding_value, commit_message_encoding_log_encoding_flag, commit_message_encoding_message_bytes
Projected from the git internals and the object model KB (162 concepts / 159 relations) — consistency-typed by MAP; the facet list after the colon IS the cross-lib dependency web.
(leaf — this is an actual skill.)
