Indexes

Two contracts, three proxies.

AccountsIndex

Enumerable address set with activation. clc-core calls add with its master key on user registration.

Call	Who	Effect
`add(account)`	owner / writer	insert; revert if present
`remove(account)`	owner / writer	swap-and-pop (order not stable)
`activate` / `deactivate`	owner / writer	toggle `have` without dropping the entry
`have(account)`	anyone	present and active
`contains(account)`	anyone	present, including deactivated
`entry(i)` / `entryCount()`	anyone	enumerate
`time(account)`	anyone	add timestamp; `NotFound` if absent

Deactivation: contains stays true, have / isActive go false.

add reverts Access() unless writers[msg.sender] || msg.sender == owner().

Events: AddressAdded, AddressRemoved, AddressActive(account, active), WriterAdded, WriterDeleted.

Token registry keyed by unique ERC-20 symbol(). Used as:

Call	Notes
`register(token)` / `add(token)`	reads `symbol()`; unique address + unique symbol; ≤32 bytes; owner/writer
`remove(token)`	owner/writer
`have(token)`	SwapPool whitelist check
`addressOf(bytes32 symbolKey)`	lookup
`entry(i)` / `entryCount()`	enumerate addresses
`identifier(i)` / `identifierCount()`	enumerate symbol keys

time / activate / deactivate are inert stubs (0 / false) for interface compatibility.

isWriter on this contract is the raw mapping. It does not treat owner as writer.

Events: AddressKey(symbol, token), AddressAdded, AddressRemoved.

Tracker bootstrap walks TokenIndex and PoolIndex with entryCount / entry, then each pool's tokenRegistry().
