AMT coverage: g5-interpretercallermeta-v1 - #224
Conversation
…ngth caps, TryFrom paths AMT g5-interpretercallermeta-v1 unit 1. The model was zero-covered; these tests discriminate serde defaults (desc/source/alias/signed_context/ caller_context/cells), the nested #[validate] chain down to ContextCell, the min/max length constraints, TryFrom bytes parse+validate, TryFrom meta item via unpack (deflate), deny_unknown_fields and the camelCase wire format.

… output encoding AMT g5-interpretercallermeta-v1 unit 2. Discriminates normalize-then- encode in the BuildItem conversion (deflate of normalized vs raw payload), the four arity guard messages (which fire before any file IO), file reading into build items, and binary vs hex output encoding. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…ir creation, subject and magic AMT g5-interpretercallermeta-v1 unit 4. Strengthens the nonexistent-file error to its wrapped message, the write_output snapshot to exact pretty JSON, adds parent-dir creation coverage, and pins the emitted meta_bytes to the rain meta document magic prefix and the subject to the keccak256 of the bare cbor item map via an independently constructed item.

…magic ls, solc artifact, subgraph constants — plus binary e2e stdin/stdout coverage AMT g5-interpretercallermeta-v1 units 3 and 5. In-file tests pin output() binary/hex file writing, validate() normalizability, schema show's four schema arms, pretty flag and unsupported message, solc artifact component extraction (including the documented null passthrough), and the KnownSubgraphs URL table with of_chain mapping. The new tests/cli.rs drives the built binary to observe stdout/stdin: magic ls and schema ls listings, schema show stdout, schema-check's success count message, and generate source over stdin to stdout.

WalkthroughThe PR adds unit and end-to-end tests for CLI commands, metadata encoding and validation, schema output, Solidity artifact extraction, subgraph mappings, and generated metadata integrity. ChangesCLI and metadata coverage
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to The PR adds metadata and CLI behavior with extensive tests, but two changed Rust files still lack required DCL-1.0 SPDX headers and the required repository quality gates have not been shown to pass. Merge readiness is moderate until the headers are added and those checks complete successfully. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

AMT coverage for group
g5-interpretercallermeta-v1(30 behaviours across 5 units), probed withnix run github:rainlanguage/adversarial-mutation-test#mutation-probeover the suitenix develop -c cargo test -p rain-metadata— the rainix-rs CI suite scoped to the one workspacemember containing every mutated file (the other two members are its dependencies, not dependents,
so their tests cannot observe these mutations).
Sequence per the AMT protocol: all 78 mutants probed against the PRE-EXISTING suite first
(30 killed, each credited to named pre-existing tests; 48 survived; 0 no-run; 0 harness errors),
then survivors worked per unit with new or in-place-strengthened discriminating tests and
re-probed to 78/78 KILLED. One deliberately unprobed sub-behaviour is recorded at the bottom.
