* fix(learning-examples): replace getProgramAccounts scan in get_graduating_tokens The pump.fun program owns over 10M accounts and no provider will scan it, so get_graduating_tokens.py could not run at all (#178). getProgramAccountsV2 is not a fix: it is a provider extension rather than core Agave, and its `limit` is a scan budget, not a result count, so one filtered answer costs ~1000 sequential pages. Rewrite discovery onto filtered programSubscribe, which applies dataSize and memcmp server-side and is accepted even by public api.mainnet-beta.solana.com. Every write to a curve pushes the full 151-byte account, so progress is computed per update with no accumulated state. Add a Geyser sibling that reports the same thing with the slot and signature behind each update. Also fix two bugs that would have survived the rewrite: the mint lookup queried SPL Token, which returns nothing for the Token-2022 ATAs that every create_v2 coin uses, and the threshold was a hardcoded constant rather than Global.initial_real_token_reserves. Closes #178 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(learning-examples): drop the graduation cutoff that filtered nothing zero_prefix_gate offered a cutoff so high that no coin could fail it, so for any --min-progress below 64.5% the subscription was unfiltered while the banner reported a filter as active. Offer only the three cutoffs that actually narrow, and say plainly when none applies. Rewrite the threshold notes in both scripts in plain English: which cutoffs exist, whether a given threshold gets one, and the part that matters — the pre-filter saves bandwidth but does not decide the answer, so the requested percentage is honoured either way. The banner now names the cutoff as a percentage instead of byte offsets. Both directions were checked against mainnet by running the filtered and unfiltered subscriptions side by side for a minute, on both transports: the filtered stream matched the below-cutoff set exactly, with 143 of 168 curves above the cutoff on WebSocket and 128 of 154 on Geyser. Also document the two scripts in the README example table, and record under throughput that getProgramAccounts over the whole pump.fun program is no longer served by any provider.
