empty_json_object
empty
any
true
case.json
{}
an object with no members: there is no property here to check
empty_json_array
empty
any
true
case.json
[]
zero records; any 'all records satisfy P' is vacuously true
empty_file
empty
any
true
case.jsonl
zero bytes; a verifier that reports success has verified nothing
whitespace_only
empty
any
true
case.jsonl
no records, but not zero bytes — a naive length check passes this
empty_graph
empty
graph
true
case.json
{}
no nodes: 'no cycle exists' is true and says nothing about your system
zero_bindings
empty
certificate
true
case.json
{ "bindings": [], "checked": 0 }
nothing was bound, so nothing was compared

the final record is cut mid-JSON: a line-wise reader may simply drop it
json_truncated_mid_object
truncated
certificate
true
case.json

invalid JSON that begins validly; a streaming parser can emit a partial result

internally consistent and tied to nothing; self-consistency is not authenticity
cert_unsigned
no_anchor
certificate
true
case.json
{ "bound": 0.001, "schema": "example/v1", "signature": null, "verdict": "PASS" }
a verdict with no signature and no pinned key: nothing attests to it
self_referential_root
no_anchor
certificate
true
case.json
{ "index": { "root": "abc123" }, "root": "abc123", "verified_against": "index" }
the artifact is checked against a value it itself supplies

chain
false
case.jsonl
{ "anchor": { "sth": "9d820cafe552ad3e28728cac1927198be0e9267a584d6a7db076d73bc9c884ac", "witnessed_by": "example-log" }, "decision": "admit", "hash": "9d820cafe552ad3e28728cac1927198be0e9267a584d6a7db076d73bc9c884ac", "prev": "0000000000000000000000000000000000000000000000000000000000000000", "seq": 0}
one record with a valid genesis pointer. A chain of length one has no LINK to check, but it is a well-formed chain and accepting it is defensible.
single_node_graph
sound_pass
graph
false
case.json
{ "a": [] }
one node waiting on nothing. A verifier MAY pass this: a system where nobody waits genuinely cannot wedge. Listed so over-refusal is visible, not scored.
bound_of_one
degenerate
certificate
true
case.json
{ "false_pass_bound": 1.0, "n": 0, "verdict": "PASS" }
a bound of 1.0 excludes nothing; passing under it is not evidence
sample_size_zero
degenerate
certificate
true
case.json
{ "failures": 0, "rate": 0.0, "trials": 0 }
0 failures in 0 trials is a rate of nothing, not a rate of zero
all_cases_skipped
degenerate
certificate
true
case.json
{ "failed": 0, "passed": 0, "skipped": 12, "tests": 12 }
every case was skipped; a green result here means nobody ran anything
not_json
malformed
any
true
case.json
this is not json at all
the correct response is a diagnosis naming the expected shape, not a verdict
wrong_root_type
malformed
any
true
case.json
"a bare string"
a string where an object was required
nan_bound
malformed
certificate
true
case.json
{"verdict": "PASS", "false_pass_bound": NaN}
NaN compares false against every threshold, so a naive `bound < t` check rejects it, but a naive `not (bound > t)` check ACCEPTS it
negative_count
malformed
certificate
true
case.json
{ "records": -5, "verdict": "PASS" }
a negative count is not a count
bom_and_crlf
malformed
chain
true
case.jsonl
{ "prev": "0000000000000000000000000000000000000000000000000000000000000000", "seq": 0}
a byte-order mark ahead of the first record breaks strict parsers silently
future_schema_version
out_of_distribution
certificate
true
case.json
{ "fields_you_do_not_know": true, "schema": "example/v99", "verdict": "PASS" }
a schema version from the future: 'I do not recognise this' is the honest answer
unknown_verdict_value
out_of_distribution
certificate
true
case.json
{ "bound": 0.01, "schema": "example/v1", "verdict": "PROBABLY_FINE" }
an unrecognised verdict string must not be coerced to the nearest known one
cyclic_where_dag_expected
out_of_distribution
graph
true
case.json
{ "a": [ "b" ], "b": [ "a" ] }
a cyclic graph handed to something expecting a DAG; infinite loop or wrong answer
seq_repeats
out_of_distribution
chain
true
case.jsonl
{ "prev": "0000000000000000000000000000000000000000000000000000000000000000", "seq": 0} { "prev": "0000000000000000000000000000000000000000000000000000000000000000", "seq": 1} { "prev": "0000000000000000000000000000000000000000000000000000000000000000", "seq": 1} { "prev": "00000000000000000000000000000000000000...
a repeated sequence number: two records claim the same position
rtl_and_unicode_ids
sound_pass
graph
false
case.json
{ "\u0645\u0633\u062a\u062e\u062f\u0645": [], "\u202eadmin": [ "\u0645\u0633\u062a\u062e\u062f\u0645" ] }
identifiers containing a right-to-left override RENDER deceptively, but the graph is genuinely acyclic. Passing it is correct; the defect is in display, not the verdict, so scoring it would be a false accusation.

a well-formed anchored chain: a working verifier SHOULD accept this
valid_acyclic_graph
positive_control

false
case.json
{ "a": [ "b" ], "b": [ "c" ], "c": [] }
a genuine acyclic wait-for graph with three nodes and two edges

case.json
{ "false_pass_bound": 0.001, "n": 4000, "schema": "example/v1", "scope": "the enumerated domain", "signature": "deadbeef", "verdict": "PASS" }
a complete certificate with a finite bound, a scope and a signature

record 3's back-pointer is wrong: a working verifier SHOULD reject this
cyclic_graph
negative_control
graph
false
case.json
{ "a": [ "b" ], "b": [ "a" ] }
a two-cycle: a working deadlock checker SHOULD reject this
