# ECP-0047: Coverage Reporting (cargo-llvm-cov)
|
|
|
|
## Why
|
|
|
|
We want high confidence in stream processing, transport, and cryptographic verification code.
|
|
That requires:
|
|
- repeatable coverage measurement, and
|
|
- a visible baseline so we can drive coverage up without guessing.
|
|
|
|
## Proposal
|
|
|
|
Adopt `cargo llvm-cov` as the canonical Rust coverage tool in this repo (already provided by `flake.nix`).
|
|
|
|
Add:
|
|
- `scripts/coverage.sh` to generate an HTML report and write a summary table to `tmp/coverage/summary.txt`.
|
|
|
|
Notes:
|
|
- `#[ignore]` E2E tests are excluded by default and do not contribute to coverage.
|
|
- We will expand unit and non-ignored integration tests in the crates that matter most for correctness
|
|
(chunk framing, manifest validation, encryption, ingest adapters).
|
|
|
|
## Reversibility
|
|
|
|
High. This adds a script and a convention; it does not change runtime behavior.
