Systematic prune per AGENTS.md test policy, one pass over every major test tree (gateway, hermes_cli, tools, agent, run_agent, plugins, cli, cron, tui_gateway, honcho/openviking, root-level): - DELETE: source-reading tests (read_text/getsource on prod files), change-detector tests (exact catalog counts, model-name snapshots, config version literals), mock-echo tests (assert a mock returns what it was told), assertion-free/trivial tests, near-duplicate parametrizations (boundaries + one representative kept), async/sync twin duplicates, cosmetic within-file variations. - KEEP (mandatory): security/redaction/approval guards, message-role alternation invariants, prompt-caching/deterministic-call-id invariants, issue-number regression tests (deduped), E2E tests. - 6 test files deleted outright (script-style/no-assert or fully redundant); conftest.py, fakes/, fixtures/ untouched. - tests/acp/conftest.py added: autouse fixture stubs the live models.dev/GitHub/Copilot/Anthropic inventory fetches that ACP server tests performed on every session create — test_server.py 147s → 3.4s, and the tests are now genuinely hermetic. - Sleep-based slowness shrunk where safe (codex_ttfb_watchdog, compression_concurrent_fork, etc.); no wall-clock assertion tightened. Verification: full hermetic suite via scripts/run_tests.sh — 2439 files, 31,130 tests passed, 0 failed, 0 flaky retries, 315s wall (baseline: 583s wall, 13,564s subprocess CPU).

"""Regression guard for #14782: json.JSONDecodeError must not be classified
|
|
as a local validation error by the main agent loop.
|
|
|
|
`json.JSONDecodeError` inherits from `ValueError`. The agent loop's
|
|
non-retryable classifier at run_agent.py treats `ValueError` / `TypeError`
|
|
as local programming bugs and skips retry. Without an explicit carve-out,
|
|
a transient provider hiccup (malformed response body, truncated stream,
|
|
routing-layer corruption) that surfaces as a JSONDecodeError would bypass
|
|
the retry path and fail the turn immediately.
|
|
|
|
This test mirrors the exact predicate shape used in run_agent.py so that
|
|
any future refactor of that predicate must preserve the invariant:
|
|
|
|
JSONDecodeError → NOT local validation error (retryable)
|
|
UnicodeEncodeError → NOT local validation error (surrogate path)
|
|
bare ValueError → IS local validation error (programming bug)
|
|
bare TypeError → IS local validation error (programming bug)
