Quality is non-negotiable. ## Context -You have **full codebase access** — you can read the full repository to understand -patterns and conventions. However, you are **diff-scoped by design**: you may only -modify files that were changed on this branch. This restriction exists to prevent -whole-codebase refactoring and to keep simplification focused on the work under review. - -## Step 1 — Identify changed code -Run: git log $(git merge-base HEAD origin/main)..HEAD --oneline -If empty: signal pass immediately — nothing to simplify. - -Run: git diff $(git merge-base HEAD origin/main)..HEAD --name-only -These are the only files you may touch. - -Run: git diff $(git merge-base HEAD origin/main)..HEAD -Read the actual changes to understand what was implemented. -(See cistern-git skill for git conventions.) - -## Step 2 — Look for simplification opportunities -For each changed file, check for: -- Unnecessary complexity and nesting -- Redundant code, dead variables, and unused imports -- Unclear names that obscure intent -- Comments that describe obvious code -- Logic that can be consolidated without sacrificing clarity -- Repeated patterns that could be a shared helper - -Do NOT touch: -- Code that was not changed on this branch -- Tests (unless they are also unnecessarily complex) -- Anything that changes what the code does - -## Step 3 — Apply changes (or skip) -If no simplifications are warranted: - ct droplet pass --notes "No simplifications required — code is already clear and idiomatic." -and stop. - -Rules when making changes: -- NEVER change behaviour — only how it is expressed -- Prefer explicit over compact -- Run go test ./... -count=1 after each file — revert immediately if anything fails - -## Step 4 — Commit -Use cistern-git skill conventions (exclude CONTEXT.md, verify HEAD advances). +You have **full codebase access**. Your environment contains: + +- The full repository checked out at the working directory +- `CONTEXT.md` describing the work item, requirements, and any revision notes + from prior review cycles + +Read `CONTEXT.md` first. + +## Protocol + +1. **Read CONTEXT.md** — understand the requirements and every revision note +2. **Check open issues** — run `ct droplet issue list --open` to get the + full list of open findings from all flaggers.

Grep for a key function or identifier from your implementation in the diff: + ```bash + git show HEAD | grep "" + ``` + **Hard gate:** if this returns nothing, your implementation was not committed. Do not pass. + +e. Verify non-trivial files changed: + ```bash + git show --stat HEAD | grep -v 'CONTEXT.md\|\.md ' | grep -c '|' + ``` + Must be > 0. If the commit only touches `.md` files: you did not commit your implementation. + **DO NOT signal pass.** Stage the missing files and commit, then re-verify from step (a). + + **Exception:** If the named deliverable in CONTEXT.md is itself a `.md` file, this check does not apply — a `.md`-only commit is correct.

If the fix is in place and no changes are needed, run: - `ct droplet pass --notes "Fix already in place — no changes required."` - and stop. Do NOT commit a no-op. -5. **Write tests first (TDD)** — define the expected behaviour with failing tests - before writing implementation code -6. **Implement** — write the minimal code to make the tests pass -7. **Refactor** — clean up without changing behaviour; keep tests green -8. **Self-verify** — run the test suite.

If you have addressed open issues, signal pass — the reviewer will verify. You cannot resolve your own issues; only the reviewer can close them.

Previously, containers ran as root with no restrictions. + +- **K8s worker token stored as Secret**: The `ST_WORKER_TOKEN` is no longer passed as a plain environment variable (visible via `kubectl describe pod`). Instead, each execution creates a dedicated K8s Secret (`st-worker-token-`) and injects it via `secretKeyRef`. The Secret is automatically cleaned up on cancellation or when the reconciler detects an orphaned job. + +- **K8s worker resource limits**: Worker pods now have default resource requests (128Mi memory / 250m CPU) and limits (512Mi memory / 500m CPU), configurable via `ST_WORKER_CPU_REQUEST`, `ST_WORKER_CPU_LIMIT`, `ST_WORKER_MEMORY_REQUEST`, and `ST_WORKER_MEMORY_LIMIT` environment variables. Previously, pods had no resource constraints, allowing runaway tests to consume unlimited resources. + +- **Execution reconciler**: A background reconciler periodically scans for orphaned `running` executions whose K8s job has finished or was never created, and marks them as `failed`. This prevents executions from staying in `running` forever when the worker crashes before reporting status. Configurable via `ST_RECONCILE_INTERVAL` (default: 60s) and `ST_RECONCILE_ORPHAN_TIMEOUT` (default: 5m). + +- **Team-scoped K8s lookups**: Cancellation endpoints now use team-scoped queries for K8s job name and worker token Secret lookups, preventing cross-team access to K8s resources. + +- **Status guard on markExecutionFailed**: The `markExecutionFailed` function now includes `AND status = 'running'` to prevent overwriting a completed or failed execution's final status. + - **Store layer extraction**: All HTTP handlers now use store interfaces instead of embedding `*db.Pool` directly. Store interfaces are defined on the handler side and implemented in `internal/store/`, making handlers testable without a running database and centralizing SQL query knowledge. Affected handlers: auth, teams, analytics, executions, reports, admin, invitations, oauth. - **Bulk test result inserts**: Report ingestion now uses `pgx.Batch` to insert test results in bulk instead of one query per result. This eliminates the N+1 insert pattern that caused 1000+ round-trips for large reports. diff --git a/README.md b/README.md index 51529a9c..6f4185cb 100644 --- a/README.md +++ b/README.md @@ -73,6 +73,16 @@ export OPENAI_API_KEY=your_api_key # Required if ST_LLM_PROVIDER=openai # Optional: disable rate limiting (test environments only — never use in production) export ST_DISABLE_RATE_LIMIT=true + +# Optional: Kubernetes worker resource limits (defaults shown) +export ST_WORKER_CPU_REQUEST=250m +export ST_WORKER_CPU_LIMIT=500m +export ST_WORKER_MEMORY_REQUEST=128Mi +export ST_WORKER_MEMORY_LIMIT=512Mi + +# Optional: execution reconciler — detects orphaned K8s jobs and marks them failed +export ST_RECONCILE_INTERVAL=60s # How often to check for orphans +export ST_RECONCILE_ORPHAN_TIMEOUT=5m # Grace period before declaring an execution orphaned ``` When `ST_SMTP_HOST` is not set the mailer runs in no-op mode — all outbound email is silently discarded.
