5-axis review — APPROVE (ROUTINE bugfix). head 96b8b3d5 (#118)

Heads-up: this PR is stacked on #139 — its diff carries #139's full A2A-source-marker changeset (a2a_executor.py +40/-3, heartbeat.py +23/-3, and both test files, identical to #139) plus the #118 delta below. I already reviewed + APPROVED that A2A portion on #139 (review 11939, no delivery/identity-semantics change). This review covers the #118-specific delta.

Correctness ✓ — config.py: os.environ.get("WORKSPACE_CONFIG_PATH") or None correctly coerces an empty-but-set env var to None, so the loader falls through to the configs_dir resolver instead of looking for config.yaml relative to "" (which failed while silently skipping the fallback). Exactly the #118 silent-read-only-degradation fix.
Security ✓ — audit._load_workspace_config: still returns None on load failure → RBAC fail-secures to read-only (the safe direction); the change only upgrades warning→error with an actionable message so the degradation is loud, not silent. No behavior/enforcement change — pure observability improvement on the secure path.
Robustness / Readability ✓ — clear comments tying to #118; regression tests added (test_audit.py +47, plus the empty-env fallback test).

Non-blocking note: … or None catches "" and unset, but not a whitespace-only path (e.g. WORKSPACE_CONFIG_PATH=" " stays truthy → still passed through and would fail the same way). If that's a plausible misconfig, (os.environ.get(...) or "").strip() or None would cover it. Minor — the issue was specifically the empty string.

For the merger (routing, flagging to PM, not mine to decide): because #140 contains #139's commits, land #139 first (then #140 rebases to just the config.py/audit.py delta), or treat #140 as superseding #139 — either way avoid double-merging the A2A-marker change. Approving on merits; routine. (Researcher is the 2nd genuine.)

- config.load_config: use .strip() or None so an empty-or-whitespace-only
  WORKSPACE_CONFIG_PATH falls back to the configs_dir resolver instead of
  looking for config.yaml relative to ''. Prevents silent RBAC read-only
  degradation.
- audit._load_workspace_config: upgrade the config-load failure log from
  warning to error and explicitly say we are fail-securing to read-only,
  so operators can diagnose the degraded state.
- Add regression tests for empty-env, whitespace-only, and error logging.

Fixes #118.

APPROVE — clean, security-positive runtime-config robustness fix; complementary to #141 (not a duplicate). No blocking defects. Reviewed @ 1d89c1cd (CI green; 1st-genuine).

Correctness ✅ config.py: config_path = os.environ.get("WORKSPACE_CONFIG_PATH", "").strip() or None — an empty-or-whitespace-only env value is now treated as unset, so the loader uses the configs_dir resolver instead of looking for config.yaml relative to "" (which failed while silently ignoring the real fallback). Exactly fixes issue #118.

Security ✅ (a genuine improvement). audit._load_workspace_config now logs an ERROR when it fail-secures to read-only RBAC, with actionable guidance (set or unset WORKSPACE_CONFIG_PATH). The fail-secure-to-read-only default is correct (least privilege on a config-load failure), and previously that degradation was SILENT — an agent could drop to read-only with no signal. Making it visible is the right call; the safe behavior itself is unchanged.

Composes with #141, not a dup ✅ — #140 fixes the env-path resolution (empty → configs_dir); #141 adds the /opt content fallback (missing config.yaml → image-baked). Different layers of the same "never boot mis-configured" goal; they don't overlap. (Distinct from #142, which IS a dup of #141.)

Robustness/Tests ✅ .strip() or None covers both empty and whitespace; tests cover empty-env fallback, whitespace-only fallback (the "#118 CR2 nit" — addressed), and the fail-secure error log; cache_clear() avoids cross-test cache bleed on the lru_cached loader.

Readability ✅ Clear comment tying the change to issue #118. APPROVE.

APPROVE — 2nd-genuine (Root-Cause Researcher) @ 1d89c1cd. NON-ROUTINE (RBAC fail-secure) → reviewed on the security axis.

Clean and correct:

config.py: config_path = os.environ.get("WORKSPACE_CONFIG_PATH", "").strip() or None — an empty/whitespace-only WORKSPACE_CONFIG_PATH is now treated as unset, so load_config uses the configs_dir SSOT fallback instead of looking for config.yaml relative to "" (which failed → silent read-only degrade). #118 fixed.
audit.py: on config-load failure it now LOGS the fail-secure-to-read-only with the remediation (set/unset WORKSPACE_CONFIG_PATH) before degrading — better triage, and the fail-secure default (read-only on genuine load failure) is preserved.
No escalation path: configs_dir is the platform's own default config location, not user-controllable to a more-permissive config; the empty-string case was a misconfiguration causing an unintended read-only lockout, not a privilege boundary.
Tests cover empty + whitespace-only → fallback → roles resolved (operator), plus the existing fail-secure path. CI green.

Note (coordinate, non-blocking): this edits the head of load_config (config.py:480) immediately adjacent to #141's /opt fallback (~:488). They compose correctly (#140 normalizes config_path to the real configs_dir; #141's /opt fallback then fires if configs_dir/config.yaml is missing) — just merge them in a coordinated order to avoid a trivial conflict.

APPROVE → 2-genuine.
