+# Launch Candidate V0 Boundary
+
+Date: 2026-05-13
+
+## Decision
+
+FlowMemory V0 now treats the local launch candidate as a complete repeatable
+developer loop, not just a set of isolated fixtures.
+
+The loop is:
+
+```text
+FlowPulse or swap-derived hook-adapter event
+-> indexer observation
+-> verifier report
+-> MemorySignal and MemoryReceipt
+-> RootflowTransition
+-> RootfieldBundle
+-> AgentMemoryView
+-> dashboard fixture
+```
+
+## What Changed
+
+- `FlowMemoryHookAdapter.afterSwap` emits `SWAP_MEMORY_SIGNAL` FlowPulse events
+  for the V0 swap-memory path.
+- The verifier can validate swap-memory artifacts using `poolId`,
+  `hookDataHash`, and `memoryRoot` commitments.
+- The launch command now generates 8 observations, 8 verifier reports, 8 memory
+  signals, 8 memory receipts, 7 Rootflow transitions, 1 Rootfield bundle, and 1
+  AgentMemoryView.
+- `npm run validate:launch` validates generated launch-core objects against
+  canonical JSON schemas.
+- `npm run fixtures:check` catches stale generated launch/dashboard fixtures.
+- `npm run launch:candidate` runs the local hardening, launch, validation,
+  drift, and claim-guardrail path.
+- Base Sepolia deploy/read commands exist for the current V0 testnet contract
+  set without committing credentials.
+
+## Boundaries
+
+This decision does not approve Base mainnet deployment, a production L1,
+tokenomics, production verifier economics, custody, dynamic fees, or a production
+Uniswap v4 hook.
+
+Contracts still cannot know `txHash` or `logIndex` during execution. The
+indexer derives those fields after receipts and logs exist.
+
+Heavy AI/model/memory/artifact data remains off-chain. On-chain and fixture
+surfaces carry roots, commitments, receipts, and status.
+
+## Required Before Public Testnet Use
+
+- Run `npm run contracts:hardening:slither`.
+- Record deployer address, chain id `84532`, contract addresses, block range,
+  source verification status, and post-deploy read evidence in the PR or issue.
+- Run the Base Sepolia reader over the deployment block range and attach the
+  generated checkpoint.
