araharah-executor e9aec5833b feat(02-02): TTL-only KV sessions with rotate-on-new + PRIV-02 storage gates (D-06/D-07/D-08/D-14) 
- sessions.ts: mintSession (crypto.randomUUID opaque token, T-02-05), rotate-on-new deletes prior session record via chat pointer (D-07), both puts carry expirationTtl: SESSION_TTL_SECONDS on the call line (PRIV-02)
- SESSION_TTL_SECONDS = 900 pairs the session envelope with the D-13 freshness window
- SessionClaim is exactly D-08: user_id, chat_id, issued_at, language_code — nothing else serializes to storage
- sessions.test.mjs: in-memory KV fake asserting finite expirationTtl on every put; D-08 key-set equality; rotate removes old token; expired-token → null (D-14 class)
- privacy.test.mjs: PG1 same-line expirationTtl source gate (auto-tightens to webhook.ts when plan 03 adds it) + PG2 no persistence-shaped exports
- 18/18 PASS across initdata + sessions + privacy suites; full plan GREEN

araharah-executor 54bffe728c feat(02-02): validateInitData — SubtleCrypto HMAC core with rejection classes (D-13, D-14) 
- GREENs the plan-01 RED vector suite: T1-T7 all PASS (10/10 cases)
- Telegram-verified two-step key derivation: secretKey = HMAC(botToken, key=salt), checkHex = HMAC(dataCheckString, secretKey bytes)
- Sort by field name, hash/signature excluded, values decoded once with '+' literal (no URLSearchParams)
- Rejection precedence: malformed (hash/user.id/auth_date) -> tampered (timing-safe hex compare) -> stale (>900s, D-13)
- Hand-rolled WebAppInitUser/WebAppInitChat types (grammy ships none); zero deps of any kind — pure (raw, botToken, opts)

araharah-executor fc5001a4eb test(02-01): hand-rolled harness + RED initdata vector suite (D-12, TDD RED) 
- bot/test/harness.mjs: zero-dep registry (test(name, fn))
- bot/test/runner.mjs: auto-discovers *.test.mjs, suite-load failure -> FAIL case, exit 0 iff all green
- bot/test/initdata.test.mjs: T1-T7 vector contract signed via node:crypto in-suite
  (T1 known-good, T2 tampered, T3 stale 3600s, T4 boundary 899/901, T5 order-independence,
  T6a-c malformed, T7 RFC-4231 node:crypto independence pin)
- demonstrated RED: 8 FAILs / exit 1 against missing src/security/initdata.ts; GREEN lands in plan 02

araharah-executor c9b6ba402d feat(02-01): bot workspace scaffold with Env contract (D-09/D-10/D-11/D-15) 
- bot/ npm workspace sibling to theme/: grammy ^1.46.0, wrangler ^4.151.3, TS ^5.9.3
- src/config.ts exports Env (BOT_TOKEN, WEBHOOK_SECRET, chat_sessions KVNamespace)
- wrangler.jsonc: main src/webhook.ts + chat_sessions KV binding (id filled in plan 03)
- .gitignore ships .dev.vars/.wrangler/ in the same commit as .dev.vars.example (D-17)
- root delegate scripts bot:test/typecheck/dev/deploy/commands
