Should it also prove the retry contract?\nProject/branch/task: gstack-plan-count-knpyoQ on main, CEO review of PLAN.md (payment test coverage).\nELI10: The plan's contract says two 502s with max_retries=1 mean exactly two charge attempts, one recorded 100 ms backoff, then PaymentUnavailable. The test as written checks only the final rejection. An implementation that never retries (one attempt, no backoff) passes. One that retries five times with no backoff also passes, as long as it eventually throws PaymentUnavailable. The factory already exposes the Stripe mock call history and the sleeper's recorded backoffs, so the evidence is free; the plan just says it will not look at it.\nStakes if we pick wrong: a retry-loop regression (zero retries, or an unbounded loop that hammers Stripe during an outage) ships green; users get instant failures on transient blips, or Stripe rate-limits the account during an incident.\nRecommendation: 2A because the plan states exact counts (two attempts, one 100 ms backoff) and Section 6 rules forbid weakening an exact count to a lower bound; the mock history and sleeper record are already exposed for exactly this purpose.\nCompleteness: 2A=10/10, 2B=7/10, 2C=3/10\n2A) Assert rejection is an instance of PaymentUnavailable AND Stripe mock call history has exactly 2 charge calls AND the sleeper record deep-equals one 100 ms backoff; build a fresh factory inside the test so both records start empty (recommended) (human: ~30 min / CC: ~2 min)\n  ✅ Rejects zero-retry, over-retry, and wrong-backoff regressions; the whole stated contract becomes executable\n  ✅ Fresh factory per test prevents call-history bleed from earlier tests, so the exact count cannot flake; failure prints the recorded arrays\n  ❌ Three assertions instead of one; must match the sleeper's actual record shape (number vs object) when implementing\n2B) Assert PaymentUnavailable AND exactly 2 charge calls, but skip the backoff assertion (human: ~20 min / CC: ~1 min)\n  ✅ Catches zero-retry and over-retry regressions\n  ✅ Does not depend on the sleeper record's shape\n  ❌ A retry loop that drops the backoff and hammers Stripe immediately still passes; the 100 ms contract goes unverified\n2C) Keep rejection-only as planned (human: ~10 min / CC: ~1 min)\n  ✅ Matches the plan text verbatim\n  ✅ Smallest possible test body\n  ❌ Passes with zero retries, five retries, or no backoff; the retry contract the plan states is not tested at all\nNet: 2A turns the plan's own sentence about two attempts and one 100 ms backoff into assertions; 2B and 2C leave part or all of it as prose.",

            "D5 — Finding F2 (Sections 2 and 6): the repeated-502 test asserts only that processPayment rejects with PaymentUnavailable. Should it also prove the retry contract?\nProject/branch/task: gstack-plan-count-knpyoQ on main, CEO review of PLAN.md (payment test coverage).\nELI10: The plan's contract says two 502s with max_retries=1 mean exactly two charge attempts, one recorded 100 ms backoff, then PaymentUnavailable. The test as written checks only the final rejection. An implementation that never retries (one attempt, no backoff) passes. One that retries five times with no backoff also passes, as long as it eventually throws PaymentUnavailable. The factory already exposes the Stripe mock call history and the sleeper's recorded backoffs, so the evidence is free; the plan just says it will not look at it.\nStakes if we pick wrong: a retry-loop regression (zero retries, or an unbounded loop that hammers Stripe during an outage) ships green; users get instant failures on transient blips, or Stripe rate-limits the account during an incident.\nRecommendation: 2A because the plan states exact counts (two attempts, one 100 ms backoff) and Section 6 rules forbid weakening an exact count to a lower bound; the mock history and sleeper record are already exposed for exactly this purpose.\nCompleteness: 2A=10/10, 2B=7/10, 2C=3/10\n2A) Assert rejection is an instance of PaymentUnavailable AND Stripe mock call history has exactly 2 charge calls AND the sleeper record deep-equals one 100 ms backoff; build a fresh factory inside the test so both records start empty (recommended) (human: ~30 min / CC: ~2 min)\n  ✅ Rejects zero-retry, over-retry, and wrong-backoff regressions; the whole stated contract becomes executable\n  ✅ Fresh factory per test prevents call-history bleed from earlier tests, so the exact count cannot flake; failure prints the recorded arrays\n  ❌ Three assertions instead of one; must match the sleeper's actual record shape (number vs object) when implementing\n2B) Assert PaymentUnavailable AND exactly 2 charge calls, but skip the backoff assertion (human: ~20 min / CC: ~1 min)\n  ✅ Catches zero-retry and over-retry regressions\n  ✅ Does not depend on the sleeper record's shape\n  ❌ A retry loop that drops the backoff and hammers Stripe immediately still passes; the 100 ms contract goes unverified\n2C) Keep rejection-only as planned (human: ~10 min / CC: ~1 min)\n  ✅ Matches the plan text verbatim\n  ✅ Smallest possible test body\n  ❌ Passes with zero retries, five retries, or no backoff; the retry contract the plan states is not tested at all\nNet: 2A turns the plan's own sentence about two attempts and one 100 ms backoff into assertions; 2B and 2C leave part or all of it as prose.": "2A: Rejection + 2 calls + [100ms] backoff (recommended)"
