Direct port of `client/stream/index.ts:#computeUnionFilter`. - Channels are unioned. - Namespaces: if any subscription omits `namespaces` (wildcard), the union is unscoped (omits the key). Otherwise, deduplicated union. - Depth: if any subscription omits `depth` (unbounded), the union is unbounded (omits the key). Otherwise, take the max. `depth=0` is a valid bounded value — never omit when all subscriptions provide it. Args: subscriptions: list of `SubscribeParams`-shaped dicts. Returns: A `SubscribeParams`-shaped dict covering every input. r<Frr>NTr )setr5addtuplesortedlistr&) rBr<wildcard_namespaces namespace_mapunbounded_depth max_depthsubchsub_namespacesns sub_depthresults rcompute_union_filterrUksK(  BH68MOI""''*b))  B LL    ..  !"&  $ .$ . .+- eBii((GGG$$  "OO  "Y%:%:!I(&*:*:;F <=<#M$8$8$:$:;;| $#w Mrcoverertargetct|dg}|dgD] }||vrdS |d}|d}|d}|d}||dS|dS||kS|dS|D]R}d} |D]F} t|| s|d} n.|t|t| z |z|krd} nG| sdSSdS)aWhether `coverer` is a superset of `target`.

Depth coverage accounts for namespace-prefix offset: a scoped coverer needs enough depth to absorb the extra levels of any deeper target namespace prefix. r<Fr r>NT)rFr5rr) rVrWcoverer_channelsrP coverer_depth target_depthcoverer_namespacestarget_namespacestpcoveredcps r filter_coversrasr7;;z26677jjR(( % % %55 &KK((M::g&&L \22 <00!  4  5},, u $  B"2r** $#2wwR </=@@A 55  4rN)r r r r )rrrrr r)rrrrr r!r r)r+rr r,)r+rr:rr r)rBrCr rD)rVrDrWrDr r)__doc__ __future__rtypingrlangchain_protocolrrrrrrr#r6r9rArUrarrrgs #"""""IIIIIIIIIIII3333 ($(&3333l//////r
