+## Codebase Patterns
+
+### Verifier file structure
+- Each task has: benchmarks/{suite}/{task_name}/tests/test.sh
+- Many tasks also have tests/eval.sh — test.sh is a thin wrapper that does `exec bash "$(dirname "$0")/eval.sh" "$@"`
+- SG-only tasks have tests/sgonly_verifier_wrapper.sh that restores repos before verification
+
+### Standard test.sh wrapper pattern (most common)
+```bash
+#!/bin/bash
+# test.sh — Harbor compatibility wrapper
+[ -f /tmp/.sg_only_mode ] && [ -f /tests/sgonly_verifier_wrapper.sh ] && source /tests/sgonly_verifier_wrapper.sh
+exec bash "$(dirname "$0")/eval.sh" "$@"
+```
+
+### Standard eval.sh pattern (oracle-based tasks)
+```bash
+#!/bin/bash
+set -eo pipefail
+ANSWER_PATH="/workspace/answer.json"
+REWARD_FILE="/logs/verifier/reward.txt"
+mkdir -p "$(dirname "$REWARD_FILE")"
+
+# ... validation logic ...
+python3 /tests/oracle_checks.py --answer "$ANSWER_PATH" --spec /tests/task_spec.json
+SCORE=$?
+# Write reward
+echo "$SCORE" > "$REWARD_FILE"
+```
+
+### Reward output convention
+- Write float 0.0-1.0 to /logs/verifier/reward.txt
+- Some older tasks write to reward.txt in current dir
+- Harbor reads from /logs/verifier/reward.txt
+
+### The 2 broken verifiers
+- k8s-rbac-auth-audit-001 (csb_sdlc_secure): test.sh lacks set -e, doesn't write reward.txt
+- grafana-platform-orient-001 (csb_sdlc_understand): test.sh lacks set -e, doesn't write reward.txt
+
+### Language field normalization
+- Canonical values: go, java, cpp, python, typescript, rust, csharp, javascript
+- Non-canonical values found and normalized: "c++"→cpp, "c#"→csharp, "java/c++"→java,cpp, "c++/c/javascript"→cpp,c,javascript, "go,protobuf"→go, "mixed"→typescript,go, "unknown"→determined per-task
+- "c" kept as canonical (curl, linux kernel, postgres are genuinely C, not C++)
+- task.toml format: language = "value" (quoted string in TOML)
+
+### ABC audit command
+- python3 scripts/abc_audit.py --suite {suite} --format table
+- python3 scripts/abc_audit.py --all --format table
+- Grade A = all critical pass + >=80% important pass
+- Grade D = any critical fail
+
+## Progress
+
+## 2026-03-07 - US-001
+- k8s-rbac-auth-audit-001 verifier already had set -eo pipefail and writes /logs/verifier/reward.txt
+- No changes needed — csb_sdlc_secure already at Grade A
+- Files changed: none
+- **Learnings for future iterations:**
+  - Always verify current state before assuming something is broken
+  - The k8s task uses verifier_lib.sh + IR pipeline pattern (different from checklist pattern)
+---
+
+## 2026-03-07 - US-002
+- Replaced thin wrapper test.sh (exec to non-existent eval.sh) with standard checklist verifier
+- Copied exact pattern from argocd-arch-orient-001/tests/test.sh (sibling task)
+- Files changed: benchmarks/csb_sdlc_understand/grafana-platform-orient-001/tests/test.sh
+- **Learnings for future iterations:**
+  - The understand suite uses two verifier patterns: checklist (most tasks) and IR pipeline (k8s)
+  - ground_truth.json in understand suite has files/symbols format, NOT required_findings format
+  - The checklist verifier degrades gracefully when GT lacks required_findings (scores 0 from empty lists)
+  - _get_primary_verifier checks if test.sh is an eval wrapper; if eval.sh is missing, it falls back to test.sh
+---
+
+## 2026-03-07 - US-003
+- Normalized language field in 94 task.toml files across all suites
+- Bulk replacements: c++→cpp (60), c#→csharp (1), java/c++→java,cpp (8), c++/c/javascript→cpp,c,javascript (3), go,protobuf→go (1), mixed→typescript,go (1)
+- Individually determined 20 "unknown" tasks: 17→go, 2→python, 1→javascript (via instruction.md/Dockerfile analysis)
+- Files changed: 94 task.toml files across benchmarks/csb_org_* and benchmarks/csb_sdlc_*
+- **Learnings for future iterations:**
+  - xargs with sed doesn't work reliably for `+` chars in patterns; use `while read f; do sed ... "$f"; done` instead
+  - "c" is a legitimate canonical value (10 tasks: curl, linux kernel, postgres) — PRD canonical list omitted it
+  - `languages_involved` is a separate TOML array field, not `language` — grep on `^language` avoids false matches
+  - Most "unknown" Org tasks are go (prometheus, kubernetes, etcd, grafana ecosystem)
+  - Branch management: verify branch AFTER checkout, not just before — stash+checkout can silently fail
