# C328 independent four-context sensitivity review

24 September 2026. All60 MT endpoint records were selected independently from frozen C286: five roles, three regular Gears, four Cainan/Terah contexts, full430 fixed. The15 SP primary endpoints remain the C322 OFF/Terah0/full430 biographies. No MT date was generated by assuming the switch offsets.

**Result:** the same-role displacement is uniform across all15 endpoints in each context. The four displacements are650,590,520 and460. C327's residual structure is exactly the restoredON/Terah60 slice; the Noah950 remainder490 is specific to that slice within this declared menu.

| MT Cainan / Terah60 | δ=SP−MT | Positive / negative / zero annual cases | Positive residuals, with multiplicity | Noah950 remainder |
|---|---:|---|---|---:|
|OFF /0|650|6 /69 /0|300×3;450×3|300|
|OFF /1|590|12 /63 /0|10×6;360×3;510×3|360|
|ON /0|520|12 /63 /0|80×6;430×3;580×3|430|
|ON /1|460|18 /57 /0|40×6;140×6;490×3;640×3|490|

Each context has75 ordered anchor/terminal comparisons, with `r=d−δ`. In total there are300 annual cases:48 positive,252 negative and no zero. The selected records reproduce `δ=650−130c−60t`; this is a verified regular context relation, not substitution of cumulative Cainan460 for regular Cainan130.

For the named G2 Noah-life partition, the SP endpoints stay3708→2758 BC. The MT Noah anchor is3058,3118,3188 or3248 in the four respective contexts. Its remaining distance to SP Noah death is300,360,430 or490. All three Gears give the same respective widths. Among all300 candidates, the only residual490 cases are the three ON/Terah60 Noah-birth→Noah-death comparisons. Selecting490 therefore selects that context **conditional on the chosen residual criterion**; the census does not establish that a source requires that criterion or prefers the context.

The admitted MT biographies preserve the same internal role spacings500,100,350,150 in every context. Consequently changing context moves the residual threshold without altering the held source-biography durations. The Noah-bound/Flood-bound500/100 modal state remains explicit; the textual502 binding is a separate source selection and is not imported into these same-Gear records.

## Exact phases and inherited slice

All eight independent inherited `±1/4` output-phase choices were tested for each annual case:600 trials per context,2400 overall. Each context has150 trials preserving its declared δ leg, annual source duration d and annual residual r; they are exactly the all-minus and all-plus versions of its75 rows. The exact positive counts are12,24,24 and36 respectively, totaling96. All600 complete exact partitions retain their annual residual signs, and mixed phases introduce no zero or sign change anywhere in the larger2400-trial menu.

The phase condition is unchanged: deviations from δ, r and d are `pA−pB`, `pB−pC` and `pA−pC`; all vanish together precisely when the three output offsets agree. This does not equate their inherited cumulative ancestry. The same two held phase offsets are used throughout; no new phase state is introduced.

The ON/Terah60 slice reproduces **all75 C327 annual rows and all600 C327 phase rows**, including coordinates, source records, durations, signs and exactness flags. This is continuity verification, not an additional independent witness.

## Reproduction and scope

`C328_Independent_Audit.py --sources DIR --out DIR` uses the standard library and frozen `C286_DATA.json`, `C322_DATA.json`, and `PREVIOUS_DATA.json` (C327). The results preserve every selected source record, all300 annual cases, all2400 phase cases and all four duration/residual distributions. **241 checks passed.** The audit, results and this review are complete and frozen for handoff.

No expansion, new endpoint/context/phase, fitted anchor, cumulative Gear or imported MT/LXX companion was used. Global paired Mirror January AD1, local junction x=1/January AD2 and no civil year zero remain unchanged. C329 is unexecuted.
