ebbfa9f124 chore(deps): upgrade to solders 0.29 / solana 0.40 and bring the rest of the dependencies current (#217)
* chore(deps): upgrade solders to 0.29 and solana to 0.40 in cookbook and tools

solana 0.40 moves TxOpts (now TxOptsModel), MemcmpOpts and TokenAccountOpts
from solana.rpc.types to solana.rpc.core, and spl.token's *Params dataclasses
to spl.token.models as pydantic models — validated and keyword-only. Three
call sites only failed against mainnet: MemcmpOpts.bytes now takes a base58
str, SyncNativeParams was built positionally, and confirm_transaction was
passed a bare "confirmed".

Also moves every cookbook and tools send path off the legacy Transaction onto
VersionedTransaction + MessageV0, and teaches the getTransaction decoder the
json and base64 encodings alongside jsonParsed — the base64 v1 fixture needs
solders 0.29 to deserialize at all.

src/ is untouched and still on the old imports; the offline suite is 3/19
until that lands.

Verified on mainnet: a 0.003 SOL buy_v2/sell_v2 round trip confirmed and the
wallet returned to SOL only, all six listeners and every read-only script run
live, five trade paths simulated with error=None.

* chore(deps): move the bot onto solders 0.29 and solana 0.40

Same three API moves as the cookbook commit, now in src: TxOpts is
TxOptsModel in solana.rpc.core, and spl.token's BurnParams/CloseAccountParams
come from spl.token.models. build_and_send_transaction builds a
VersionedTransaction from MessageV0 with no lookup tables, so the bot no
longer sends a legacy transaction anywhere.

verify_transaction_v1 proved the log route by stripping the logs and expecting
nothing back, which only held while solders could not read a v1 envelope. On
0.29 it can, so the check is inverted: make the envelope unreadable, keep the
logs, and the create must still arrive. A second check pins the envelope
fallback, so a decode regression is reported rather than silently absorbed by
the log route.

Offline: 19/19. Live on mainnet, funds returned:
- tools/simulate_bot_buy_path: zero-RPC buy path, err=None, 107,015 CU
- tools/simulate_v2_trades: buy_v2 95,573 CU, buy+sell 174,190 — both inside
  the existing 180k/120k limits, so no retune
- tools/live_v2_round_trip: buy_v2 + sell_v2 both landed
- tools/live_listener_matrix: all four listeners detected; logs and pumpportal
  ran full round trips; geyser and blocks both drew a coin on an unconfigured
  quote mint and correctly refused to size a buy. Every ATA closed.

* chore(deps): bring the rest of the dependencies to current

Every remaining dependency is now at its latest release, with the floors
raised to the versions actually tested rather than the oldest that resolves:

  grpcio        1.73.1 -> 1.84.0    grpcio-tools 1.73.1 -> 1.84.0
  protobuf      6.33.5 -> 7.36.2    uvloop       0.21.0 -> 0.22.1
  pyyaml        6.0.2  -> 6.0.3     python-dotenv 1.2.2 -> 1.2.3
  construct     2.10.70 (floor)     websockets   17.1 (floor)
  ruff          0.12.4 -> 0.16.8

aiohttp and base58 were already current. winloop is left at its old floor:
it is Windows-only and cannot be installed, let alone tested, here.

protobuf 7 arrives with grpcio-tools 1.84 and is the only major. The
committed geyser stubs are gencode 6.31.1 and still pass
ValidateProtobufRuntimeVersion against it; they are not regenerated, because
the committed files import each other absolutely and protoc does not emit
that, so the output would need rewriting. Noted in CLAUDE.md with the
verification date.

ruff 0.16 needs no config change. The repo-wide baseline moves 1680 -> 1713
because the rules moved, not the code; CLAUDE.md carries the new figure so it
is not misread as a regression.

Verified per dependency, not just in aggregate: all four bot configs load
under the new pyyaml/dotenv; the logs, blocks and pumpportal listeners run
under the uvloop policy bot_runner installs; both geyser paths (token
listener and the account-filtered graduation watcher) run under grpcio 1.84 /
protobuf 7. Offline 19/19, including verify_listener_cancellation for
websockets. One more live buy_v2/sell_v2 round trip on the final set, both
landed, ATA closed.

* fix(utils): redact RPC credentials from every log record

The provider endpoints carry their API key in the URL and the HTTP clients log
a full request URL at INFO, so anything that raises the root logger to INFO
prints the key. tools/cleanup_accounts.py did, four times, in a terminal.

It was already silencing httpx and httpcore by name. That stopped working the
moment solana-py 0.40 switched to httpx2: the rename took the guard with it
and nothing said so. Naming the clients is now a convenience on top of the
real control — install_secret_redaction masks the value itself, at log-record
creation, whichever logger emits it.

It redacts the *rendered* message rather than record.msg plus the string
arguments. The first version of this did the latter and still leaked: httpx2
passes its URL as a URL object, so the type check skipped the only argument
carrying the key. Confirmed by forcing httpx2 back to INFO and watching the
key print anyway. The host is kept, so a log line still says which provider
answered.

Installed from get_logger, from both logging.basicConfig sites, and from
setup_file_logging before it attaches the handler — logs/ outlives a terminal.

verify_no_rpc_credentials_logged covers all of it, including the non-str
argument. Checked against the defeated version first: it fails there and
passes here. Suite is 20/20.

* docs(agents): make a real bot run the verification, not the simulations

The ground rule said never to run a bot with real funds, which points at the
tools/ harnesses instead. Those call the buyer, seller and listeners directly:
they skip bot_runner, config loading, the trader loop, the exit strategy and
cleanup, so passing there says nothing about the paths only a full run reaches.
Verification is a real run, with explicit approval for that session, covering
every mode the change touches and ending with the wallet holding SOL only.

Also records why a run can look clean when nothing happened: pump_bot runs every
bots/*.yaml, three of the four committed configs ship enabled: false, and with
all of them disabled it prints nothing and exits 0. The log file is the tell.

* docs(utils): keep the redaction comment provider-neutral

The parameter list is what matters, not which provider uses which spelling.

"""Watch for pump.fun coins approaching graduation, over Geyser gRPC.
Usage:
uv run cookbook/pumpfun/graduation/pumpfun_watch_graduating_geyser.py
uv run cookbook/pumpfun/graduation/pumpfun_watch_graduating_geyser.py --min-progress 95
Needs GEYSER_ENDPOINT, GEYSER_API_TOKEN and GEYSER_AUTH_TYPE in .env, plus
SOLANA_NODE_RPC_ENDPOINT for the two things the stream cannot answer: the Global
baseline and each coin's mint. Geyser is a paid add-on, so `pumpfun_watch_graduating_programsubscribe.py`
is the portable version of this report — it runs on any endpoint, including the public
one. This variant exists because Geyser is common among traders and gives you the slot
and transaction signature behind every update, which the WebSocket feed does not.
Why a subscription and not `getProgramAccounts`: the pump.fun program now owns over
10 million accounts, and every provider refuses to scan it — the rejection is on
program size, before filters apply. A curve can only approach graduation by being
traded, and every write pushes the full account — 125 bytes as `create_v2` allocates
it, or 151 once `extend_account` has run on it — so each update carries everything
needed to compute progress: no accumulated state, no cold start beyond the next
trade.
Selecting a graduation threshold
--------------------------------
Progress is measured against `Global.initial_real_token_reserves` (~793.1M tokens)
read from chain, not a hardcoded constant, because a mayhem coin can launch with
different virtual params and would otherwise show the wrong percentage.
The pre-filter the server applies can only match exact bytes, so it cannot do
"anything above 90%". It can only do a few fixed cutoffs. `--min-progress` uses the
closest cutoff that is still wide enough, then makes the exact comparison here:
filter cutoff ≈ graduated past
2 zero bytes @ 30 281.5M tokens left 64.5%
3 zero bytes @ 29 1.1M tokens left 99.86%
4 zero bytes @ 28 4,295 tokens left 99.9995%
--min-progress pre-filtered by the server?
below 64.5% no, every curve arrives and is filtered here
64.5% to 99.86% yes, at the 64.5% cutoff
99.86% and up yes, at the 99.86% cutoff
So the pre-filter saves traffic, it does not decide the answer — whatever percentage
you ask for is honoured either way. Low thresholds just cost more bandwidth. If you
want to hand-tune, pick a different cutoff from the table: the last moments before
migration want the 3-byte one, a wider funnel the 2-byte one.
Checked against mainnet by running the filtered and unfiltered subscriptions side by
side for a minute: same curves, nothing dropped, nothing extra.
This script does **not** filter on `datasize`. Earlier it named two
account-filter groups, one per enumerated length (125 and 151), because
Geyser ORs across named groups and a single group ANDs its own filters
together — there was no way to ask one group for "datasize 125 or 151".
That shape stopped being enough once a third live length (256 bytes) turned
up, and `extend_account` can grow a curve to any length the program allows,
so no finite set of named groups closes the gap for good. Dropping `datasize`
collapses back to the single group this script had before lengths were
enumerated at all: the discriminator memcmp alone already restricts delivery
to `BondingCurve` accounts, so nothing is lost by not naming a length. A
client-side `MIN_CURVE_LEN` floor discards anything shorter than the
smallest real struct, so a stray short/legacy account still can't reach the
decoder.
**Bandwidth trade-off, measured 2026-09-15 directly over Geyser** (not
borrowed from the WebSocket script's measurement — Geyser reports slot and
signature per update and its named-group model batches differently, so it
gets its own number). Two *separate* concurrent gRPC streams over the same
120s window, so both see the identical trade activity without the
sequential-window volume-swing problem (a first attempt comparing sequential
windows was unreliable for exactly that reason — see
`pumpfun_watch_graduating_programsubscribe.py`'s module docstring): one stream subscribed with
this script's old two named groups (`datasize` 125 and 151), the other with
a single unfiltered group. The filtered stream took in 6,754 updates /
2,340,863 proto bytes; the unfiltered stream took in 6,761 updates /
2,337,304 proto bytes — a 1.001x update ratio and a 0.998x byte ratio,
i.e. no measurable cost. The 7-update difference was the 256-byte curve
(`EJpNsfxnTB6mtVdzrTcgQ9xfywobHSSsUtu1Gh1GFvEg`) that no enumerated length
could ever match; the filtered stream structurally cannot see it at all.
`getAccountInfo` on that same curve, run directly the same day, confirms it:
still 256 bytes, discriminator intact, and it decodes cleanly through this
repo's own IDL-driven decoder — the bytes past the documented fields are
zero padding.
UNVERIFIED here: whether the original 49-byte layout (no `creator` field) is
still written anywhere. None of the 6,761 unfiltered updates in the
measurement above were that length, but that is one 120s window, not proof
of absence.
