fix(loop): guard bare function calls against set -e script termination

[timothy-20]

Closed: Superseded by #208 (refactor/remove-set-e), which removes set -e entirely — making the bare call guards in this PR unnecessary.

Walkthrough

The PR adds question-detection to response analysis, surfaces asking_questions/question_count, integrates that signal into the circuit-breaker to suppress no-progress increments, adds semantic version checks and an optional auto-update flow for the Claude CLI, redirects live-mode stderr to per-run logs, and updates tests and templates to exercise these behaviors.

Changes

Cohort / File(s)	Summary
Response analysis & question detection lib/response_analyzer.sh	Added QUESTION_PATTERNS and detect_questions(); analysis now emits asking_questions and question_count for both JSON and text paths; detect_questions exported.
Circuit breaker progress handling lib/circuit_breaker.sh	record_loop_result() now reads asking_questions and treats question-asking as non-progress without incrementing stagnation counters; log_circuit_transition() writes fallback single-entry history if jq fails.
Startup, versioning & auto-update ralph_loop.sh, lib/enable_core.sh, setup.sh, templates/ralphrc.template	Added CLAUDE_AUTO_UPDATE flag (default true), compare_semver(), check_claude_version(), check_claude_updates(); startup now validates version and optionally attempts npm-based update (non-blocking on failure); propagated config into .ralphrc template and setup.
Process, stderr & lifecycle ralph_loop.sh	Redirects Claude CLI stderr to per-execution stderr files in live and non-live modes, introduces _CLAUDE_PID and _CLEANUP_DONE guards, centralizes cleanup/trap handling, and ensures loop context always built (including corrective messaging when prior loop asked questions).
Documentation / Manifest CLAUDE.md	Documented new analysis fields, question-detection behavior, version-check/update flow, live-mode stderr handling, and loop suppression behavior.
Tests (restructure & additions) tests/unit/... (test_cli_modern.bats, test_json_parsing.bats, test_circuit_breaker_recovery.bats, test_exit_detection.bats, test_session_continuity.bats, test_file_protection.bats, test_integrity_check.bats, test_rate_limiting.bats)	Added extensive question-detection and semver tests; updated live-mode stderr tests; removed/consolidated many session, saturation, and optional-file tests; adjusted mktemp/date usage for portability; added resilience test for corrupted history file. Overall test counts changed.

532-535: Inline test function diverges from production implementation.

The inline build_claude_command uses --continue (line 534), but the production code in ralph_loop.sh (lines 1127-1140 per relevant snippets) uses --resume "$session_id" instead. The production code explicitly avoids --continue because it "can hijack active Claude Code sessions" (Issue #151).

While this may not break current tests (since CLAUDE_USE_CONTINUE is often false in test scenarios), it could mask regressions if session continuity behavior is tested. Consider syncing this inline copy with the production implementation.

♻️ Proposed sync with production

-        CLAUDE_CMD_ARGS+=("--continue")

⚠️ Potential issue | 🟠 Major

EXIT trap currently clobbers successful completion state.

On Line 1624, trap cleanup EXIT runs cleanup() on normal exits too. Since Lines 1615-1619 only gate on loop_count > 0, successful runs are rewritten as manual_interrupt/interrupted, overwriting the final status set by main().

     if [[ "$_CLEANUP_DONE" == "true" ]]; then return; fi

⚠️ Potential issue | 🟡 Minor

Bug: Single quotes prevent variable expansion in grep command.

The $script variable inside single quotes at line 1457 won't be expanded. This will cause the test to fail or look for a literal $script file.

🐛 Proposed fix

-    run bash -c "grep -c '|| true' <(sed -n '/Analyze the response/,/Get file change count/p' '$script')"
+    run bash -c "grep -c '|| true' <(sed -n '/Analyze the response/,/Get file change count/p' \"$script\")"

Note: The escaped double quotes (\") are needed because this is inside a bash -c "..." string.

check" and return 0), and guard the command substitution so a failing npm
invocation doesn’t propagate under set -e (for example run the npm view call in
a subshell with its exit ignored or capture its exit/status and set
latest_version to empty on failure); update references to latest_version
assignment and any early returns in check_claude_updates() accordingly so
missing or failing npm simply logs and returns 0 rather than terminating the
script.

Guard npm command availability in check_claude_updates() to prevent startup hard-exit.

At line 653, the command substitution latest_version=$(npm view ...) will terminate the entire script under set -e when npm is not available, regardless of stderr redirection. This breaks the intended non-blocking startup behavior — the function is designed to gracefully handle missing updates but currently fails if the npm binary itself doesn't exist.

The fix requires two changes:

1. Check npm availability before attempting the command
2. Guard the assignment with proper error handling to prevent subshell exit propagation

Proposed fix

check_claude_updates() {
    if [[ "${CLAUDE_AUTO_UPDATE:-true}" != "true" ]]; then
        return 0
    fi

+   if ! command -v npm >/dev/null 2>&1; then
+       log_status "INFO" "Skipping Claude CLI auto-update check (npm not available)"
+       return 0
+   fi

    local installed_version
     installed_version=$($CLAUDE_CODE_CMD --version 2>/dev/null | grep -oE '[0-9]+\.[0-9]+\.[0-9]+' | head -1)
     if [[ -z "$installed_version" ]]; then
         return 0
     fi

     # Query latest version from npm registry
     local latest_version
-    latest_version=$(npm view `@anthropic-ai/claude-code` version 2>/dev/null)
-    if [[ -z "$latest_version" ]]; then
+    if ! latest_version=$(npm view `@anthropic-ai/claude-code` version 2>/dev/null) || [[ -z "$latest_version" ]]; then
         log_status "INFO" "Could not check for Claude CLI updates (npm registry unreachable)"
         return 0
     fi

In `@ralph_loop.sh` around lines 651 - 657, In check_claude_updates(), avoid
hard-exit when npm is missing by first checking for the npm binary (e.g., if !
command -v npm >/dev/null; then log_status "INFO" "npm not found; skipping
Claude CLI update check" and return 0), and guard the command substitution so a
failing npm invocation doesn’t propagate under set -e (for example run the npm
view call in a subshell with its exit ignored or capture its exit/status and set
latest_version to empty on failure); update references to latest_version
assignment and any early returns in check_claude_updates() accordingly so
missing or failing npm simply logs and returns 0 rather than terminating the
script.

⚠️ Potential issue | 🟠 Major

Handle analyze_response failure before using derived analysis signals.

analysis_exit_code is captured but ignored. If analysis fails, downstream calls can consume stale .response_analysis state and skew exit/circuit decisions.

-        # Update exit signals based on analysis
-        update_exit_signals || true
-
-        # Log analysis summary

In `@ralph_loop.sh` around lines 1489 - 1496, The code currently ignores a failing
analyze_response call (analysis_exit_code is set but not acted upon), which can
let update_exit_signals and log_analysis_summary operate on stale
.response_analysis state; modify the control flow in the block that calls
analyze_response, update_exit_signals, and log_analysis_summary so that if
analyze_response returns non-zero you either (a) skip calling
update_exit_signals and log_analysis_summary and propagate or handle the error
immediately, or (b) refresh/clear the .response_analysis state before calling
them; specifically change the sequence around the analyze_response invocation in
the function that declares analysis_exit_code so that analyze_response's exit
code is checked and handled (using analyze_response, update_exit_signals, and
log_analysis_summary identifiers to locate the code).
