Implemented STRM, StreamingPayments, the launch manifest, documentation, and vendored test dependencies.

• Offline build passes.
• All 21 permanent tests pass.
• Formatting check passes.
• Separate agent review found no blocking issues; results are in REVIEW.md.

No transactions were broadcast. Platform manifest validation and release admission remain with the deployer.

Done. launch.json is the only file changed.

What I found

The tree already had a launch.json, but it wasn't a valid evm_project manifest — it used fields the schema forbids (additionalProperties: false) and wrong field names:

Was	Problem
chainId, token.totalSupply, token.constructorArgs	not manifest fields — supply/chain come from policy; the token takes no constructor args
"contract": "src/Stream.sol:Stream"	must be a bare identifier matching ^[A-Za-z_][A-Za-z0-9_]{0,31}$
contracts[].name	not a schema property
pool.currency	must be pool.pairedCurrency
(missing) notes	required

What it now says

• token: Stream / "Stream" / STRM / 18 — matches src/Stream.sol, whose constructor is zero-argument and mints 1_000_000_000 ether to msg.sender with no mint path.
• contracts: a single entry, StreamingPayments, constructorArgs: ["$token"] — matches constructor(address token_), the contract's only argument. No $owner: the contract has no owner, admin, or fee, so naming one would be wrong.
• pool: ETH (zero address), fee 3000, tickSpacing 60, sqrtPriceX96 79228162514264337593543950336, no hook.
• notes (3480 / 4000 chars): token invariants, the single backward $token reference, CEI ordering, the exact-balance-delta check that rejects lying tokens, the cancel accounting identity (recipientAmount + senderAmount == deposit - withdrawn), events, the reentrancy guard, and test coverage. It also states plainly that supply/allocations/owner/chain/hashes are not manifest fields.

Verification

• Schema check (written in test/scratch/, not submitted): all constraints pass — key sets, identifier patterns, MerkleDistributor not used, uniqueness, backward-reference and address-slot rules, initialPrice < 2^256, notes length.
• forge build --offline — compiles. The only output is pre-existing erc20-unchecked-transfer lint warnings in the test files, which are intentional there.
• forge test --offline — 21 passed, 0 failed across 3 suites, including the reentrant-token and token-permission-failure cases.
• git status — M launch.json and nothing else. lib/ is committed as ordinary blobs, not a submodule.

One note: the repo root doubles as the seat's home directory, so .gitconfig, .bashrc, .gitmodules and similar show as untracked. Those pre-date this task, are outside the paths I may touch, and I left them alone — the root .gitmodules isn't even readable under the sandbox.

No substantiated defects found. Wrote {"findings":[]} to .imd-findings.json.

Reviewed contracts, tests, protected checks, and manifest. Independently checked 51,457 arithmetic cases. Foundry tests were not rerun; implementation files remain unchanged.
