• 🟡 (09:13) Working tree modifications include .lore.md; packages/cli/plugins/sentry-cli/skills/sentry-cli/references/{dashboard.md,event.md,explore.md,feedback.md,issue.md,log.md,replay.md,span.md,trace.md}; packages/cli/src/lib/constants.ts; packages/cli/test/lib/constants.test.ts; and packages/cli/test/lib/security/sntrys-claim-mismatch.test.ts.
• 🔴 (09:13) User stated adversarial parseSntrysClaim inputs always return undefined instead of a partially trusted result.
• 🔴 (09:13) User stated parseSntrysClaim never throws on adversarial input.
• 🟡 (09:13) packages/cli/test/lib/token-claims.property.test.ts imports constantFrom, assert as fcAssert, property, string, stringMatching, and tuple from fast-check; describe, expect, and test from vitest; parseSntrysClaim from ../../src/lib/token-claims.js; mintSntrysToken from ../helpers.js; and DEFAULT_NUM_RUNS from ../model-based/helpers.js.
• 🟡 (09:13) The property test defines httpsUrlArb as hostnames matching /^[a-z][a-z0-9-]{0,30}(\.[a-z][a-z0-9-]{0,30}){0,4}$/, mapped to https://${host}.
• 🟡 (09:13) Property tests run arbitrary strings of maximum length 4000 through parseSntrysClaim; if the result is not undefined, they require result.url to be a non-empty string. This property uses { numRuns: DEFAULT_NUM_RUNS * 4 }.
• 🟡 (09:13) A separate property generates sntrys_${rest} where rest is any string up to 1000 characters, asserts parseSntrysClaim(input) does not throw, and runs { numRuns: DEFAULT_NUM_RUNS * 4 }.
• 🟡 (09:13) Round-trip property tests mint claims with iat: 1_700_000_000, arbitrary httpsUrlArb URLs, and org: "x" via mintSntrysToken; parseSntrysClaim(token)?.url must exactly equal the minted URL. This test uses { numRuns: DEFAULT_NUM_RUNS }.
• 🟡 (09:13) Another round-trip property uses iat values selected from 1, 100, 1_700_000_000, or Date.now() together with httpsUrlArb and org: "x"; each minted token must yield a defined parseSntrysClaim(token) result. This test uses { numRuns: DEFAULT_NUM_RUNS }.
• 🟡 (09:13) Forgery property tests mint attacker-selected httpsUrlArb values with iat: 1_700_000_000 and org: "anything"; parseSntrysClaim(forged)?.url must equal forgedUrl. The test documents that parser output is a hint rather than a trust source and uses { numRuns: DEFAULT_NUM_RUNS }.
