Field ledger

Field/path Offset and width Representation Claimed meaning Physical confidence Representation confidence Semantic confidence Evidence Status
PABR signature table +0, 4 validated reserved byte range Pearl Abyss table framing Certain Certain Certain Exact PABR bytes are validated by the shared bss helper and intentionally omitted Closed
ratioGroupCount, ratioGroups[] +4, 4 then groups retained u32 peek and counted array Source-code groups Certain Certain High Count frames four groups and every nested source repeats its enclosing source Closed
ratioGroups[].sourceCode group +0, 1 retained u8 Source namespace code Certain Certain High Repeated by all nested entries; code set matches the trade entry namespace byte Closed
ratioGroups[].entries[] group +1, 4 then ten-byte entries count consumed; entries retained Directed conversions Certain Certain High Eight entries exhaust all group bodies; repeated-source validation rejects inconsistent branches Closed
entries[].sourceCode, targetCode entry +0, 1; +1, 1 retained u8 values Source and target namespaces Certain Certain High Reciprocal four-code conversion matrix and exact reference equality Closed
entries[].reserved02 entry +2, 1 zero-validated reserved byte range Structural padding Certain Certain Unknown All eight bytes are zero and the BSD check rejects nonzero input Closed
entries[].marker24 entry +3, 3 retained u24().is(0x492ae6) Structural marker Certain Certain Unknown All eight entries store the marker and the native validator discriminates corruption Closed
entries[].ratioNumerator entry +6, 4 retained u32 Million-based multiplier numerator Certain Certain High Values form the reciprocal conversion matrix preserved by the exact snapshot Closed
entry framing each entry, 10 struct(...).fixedLength(10) validation Complete conversion-entry grammar Certain Certain Certain Fixed-length validation covers every byte of all eight entries Closed
thresholdCount, thresholds[] after groups, 4 then 12-byte rows retained u32 peek and counted array Ordered threshold records Certain Certain High Count frames five rows immediately before the footer Closed
thresholds[].thresholdValue row +0, 4 retained u32 Inclusive value boundary Certain Certain High Ordered series begins at zero and matches the complete reference output Closed
thresholds[].reserved04 row +4, 4 zero-validated reserved byte range Structural padding Certain Certain Unknown Every word is zero and the BSD check rejects nonzero input Closed
thresholds[].ratioNumerator row +8, 4 retained u32 Million-based multiplier numerator Certain Certain High Monotone multiplier series aligns with the stored boundaries Closed
threshold framing each row, 12 struct(...).fixedLength(12) validation Complete threshold-row grammar Certain Certain Certain Fixed-length validation covers all five threshold rows Closed
footer.footerOffset final struct +4, 4 retained informational u32 Stored footer start Certain Certain Certain Value 172 identifies the final twelve-byte footer; no runtime footer assertion is imposed Closed
footer.reserved00, footer.reserved08 final struct +0, 4; +8, 4 informational reserved byte ranges, omitted Footer framing capacity Certain Certain Unknown Both byte ranges are declaratively consumed without capture-specific footer validation Closed

Active assumptions

Findings

ID Finding Evidence Schema/documentation impact Status
ITE-01 The conversion series is evidence, not a closed production domain. One installed plaintext capture contains the four groups, eight entries, and five thresholds Production validation is structural and relational rather than value-list based Closed
ITE-02 The BSD migration exactly preserves all non-byte values while omitting framing bytes. Full normalized match with SHA-256 a69feeae0c8f073ec3b2024951668fcb3d9fd9aa152c80f92832789b1299203b The adapter removes only the legacy header string; the footer value remains Closed
