Problem and change

The IAM script hides every failure behind one generic diagnostic. Emit only a literal allowlisted Blocked category and read phase (token acquisition, role GET, getIamPolicy), with a fixed unknown fallback. Convert token subprocess failures to a fixed authentication category without exposing stderr.

Authority checks, dry-run/apply gates, mutation logic, exit status 1, single-attempt requests and no-retry behavior are preserved. Only the script and its offline tests change. No workflow dispatch, IAM operation, environment/secret update or PAPER start was performed.

Validation

• Tests first: 30 new diagnostic cases failed before the fix; 26 existing cases passed.
• Focused suite: 56 passed, including hostile exception text, unknown category/phase, subprocess stderr/timeout/executable failure, invalid tokens, HTTP rejection, transport failure and invalid JSON in each remote read phase.
• Frozen environment (uv sync --frozen --extra test): full pytest suite 3172 passed, 1 skipped, 431 subtests passed; Ruff passed; Node contracts 11 passed; diff check passed; documentation check 0 blocking / 1 existing advisory.
• Initial full run using a reused environment failed because its installed UES revision differed from uv.lock; the isolated locked environment above resolved those failures.
• AST comparison confirms authority gates, role/policy validation and the entire execute function (including mutations) are unchanged.
• Central checker: publication-check/2.0-advisory, build 83d9d1130377; complete tracked tree findings=1487, matching lines=1476. Advisory scan; changed-file findings=8, all in existing code/fixtures. No new matching lines were added. These matches do not establish credential content.

First 20 central-checker matches (shared-masker output):

Risk and limits

Diagnostics only; the prior remote failure remains unproven until a separately authorized future dry-run. This Draft grants no merge or execution authority. No labels or merge request are part of this job.

AI assistance

Codex, gpt-6.1-sol, implemented and verified this bounded diagnostic change.
