From 1511fb5f59d244ec88ab9fef684b7c48ff9295c2 Mon Sep 17 00:00:00 2001 From: Alessandro Franceschi Date: Tue, 1 Sep 2026 20:07:03 +0200 Subject: [PATCH 1/9] Add explain observability and inference request compatibility `piace explain` accepts --debug and --debug-dump-dir, the two observation options compare and capture already had, so a rejected inference request can be diagnosed rather than guessed at. The bearer token is a header, so it reaches no dump file. services.inference gains token_limit_param, selecting max_tokens (the default) or max_completion_tokens: OpenAI's GPT-5 family rejects the former outright, and OpenAI-compatible servers other than current OpenAI only understand it. It also gains an optional temperature, sent only when set: PIACE previously hard-coded temperature and seed into every request, Claude 4+ and GPT-5 reject a non-default temperature with a 400, and seed never left a mark anywhere. Pinning them never made a model-generated assessment reproducible: a provider-side model revision still moves the bytes. Dependency-graph edge groups are no longer sent for assessment. An edge change is a consequence of the resource changes around it, carries no before/after pair to reason about, and a run's edges routinely outnumber its resource changes, so sending them spent the group budget and returned a wall of unknown risk indications. The deterministic report still lists every edge group; groups_total now counts what was eligible. --- CHANGELOG.md | 46 ++++++ README.md | 37 ++++- cmd/piace/acceptance_assumptions_test.go | 13 +- cmd/piace/acceptance_explain_debug_test.go | 122 ++++++++++++++ cmd/piace/acceptance_explain_test.go | 8 + cmd/piace/debug.go | 73 +++++++++ cmd/piace/main.go | 23 ++- ...e-assessment-out-of-the-result-document.md | 4 +- examples/services-explain-only.yaml | 96 ++++++++++- examples/services-with-inference.yaml | 17 ++ internal/assess/interpret.go | 4 + internal/assess/interpret_test.go | 7 +- internal/assess/produce_test.go | 16 +- internal/assess/request.go | 41 ++++- internal/assess/request_test.go | 97 +++++++++-- internal/assess/testdata/request.golden.json | 4 +- internal/config/inference.go | 15 ++ internal/config/resolve/inference.go | 15 ++ internal/config/resolve/inference_test.go | 42 +++++ internal/inference/client.go | 51 +++++- internal/inference/client_test.go | 98 ++++++++++- internal/inference/debug.go | 152 ++++++++++++++++++ internal/inference/request.go | 31 ++-- internal/report/doc.go | 8 +- internal/report/html.go | 2 +- internal/report/html_template.go | 14 +- .../report/testdata/sample_report.golden.html | 7 + internal/report/text.go | 2 +- 28 files changed, 970 insertions(+), 75 deletions(-) create mode 100644 cmd/piace/acceptance_explain_debug_test.go create mode 100644 internal/inference/debug.go diff --git a/CHANGELOG.md b/CHANGELOG.md index 42e447f..d686fa9 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -21,8 +21,54 @@ follows [Semantic Versioning](https://semver.org/spec/v2.0.0.html). unchanged and unrelated: it names the environment to snapshot, not the candidate environment under test. +- **`piace explain --debug` / `--debug-dump-dir DIR`**: the two observation + options `compare` and `capture` already accept now work on `explain` too, so + a rejected inference request can be diagnosed without guessing. `--debug` + prints one stderr line for the inference round trip: method, URL, HTTP + status, duration, request and response body sizes, and the response body's + top-level JSON member names. `--debug-dump-dir` additionally writes the raw + request and response bodies to `0600` files in DIR: the request-body dump is + the exact catalog-derived payload PIACE sent, and the response-body dump of a + 4xx is where a provider names the field it rejected.
