Fix typo in test error message where "MustParseBig" was incorrectly 
used instead of "MustParseUint64" in the TestMustParseUint64Panic 
function. 

The test still functions correctly, but now the error message 
accurately reflects the function being tested.

Remove redundant duplicate test vectors. The two entries were identical
and back-to-back, providing no additional coverage while adding noise.
Keeping a single instance maintains test intent and clarity without
altering behavior.

… correctly (#32627)

Fix the t.Fatalf format arguments in TestBadBlockStorage to match the
intended #index output. Previously, the left number used i+1 and the
right index used the block number, producing misleading diagnostics.
Correct mapping improves test failure clarity and debuggability.

A PR in the specs repo broke our existing links:
ethereum/execution-specs#1416

This PR fixes it and adds the Prague and Osaka specs.

…ansactions (#32656)

This pull request introduces a queue for legacy sidecar conversion to
handle transactions that persist after the Osaka fork. Simply dropping 
these transactions would significantly harm the user experience.

To balance usability with system complexity, we have introduced a
conversion time window of two hours post Osaka fork. During this period, 
the system will accept legacy blob transactions and convert them in a 
background process.

After the window, all legacy transactions will be rejected. Notably, all
the blob transactions will be validated statically before the conversion, 
and also all conversion are performed in a single thread, minimize the risk 
of being DoS.

We believe this two hour window provides sufficient time to process
in-flight legacy transactions and allows submitters to migrate to the 
new format.

Print the `Truncating from head` log only if head truncation is needed.

Address #32646

https://go.dev/ref/mod#go-work-file advises against checking `go.work`
files because they can interfere with local development. We added the
workspace file in order to make `go test` and other tools work across
multiple modules. But it seems to cause weird issues with the
`go.work.sum` file being modified, etc.

So with this PR, we instead run all the `ci.go` commands for all modules
in the workspace manually.

This change replaces wrapping a stale outer err with the iterator’s own
error after Next(), and switches the post-BlockAndReceipts() check to
use the returned err. According to internal/era iterator contract,
Error() should be consulted immediately after Next() to surface
iteration errors, while decoding errors from Block/Receipts are returned
directly. The previous code could hide the real failure (using nil or
unrelated err), leading to misleading diagnostics and missed iteration
errors.

…as calculation (#32714)

The parent header was missing the BaseFee field when calculating the
reserve price for EIP-7918 in the Osaka fork, causing a nil pointer
dereference. This fix ensures BaseFee is properly set from ParentBaseFee
in the environment.

Added regression test case 34 to verify Osaka fork blob gas calculation
works correctly with parent base fee.

This adds the conversion for the legacy sidecar if these
transactions are reorged out after the osaka.

This PR fixes the fork detection of `eth_simulateV1`, particularly
for networks that are post-merge since genesis, like Hoodi.

This fixes `go run build/ci.go install`. It was failing because we
resolved all main packages by parsing sources, which fails when the
source directory contains multiple modules.

This implements the conversion of existing blob transactions to the new proof 
version. Conversion is triggered at the Osaka fork boundary. The conversion is 
designed to be idempotent, and may be triggered multiple times in case of a reorg 
around the fork boundary. 

This change is the last missing piece that completes our strategy for the blobpool 
conversion. After the Osaka fork,

- new transactions will be converted on-the-fly upon entry to the pool
- reorged transactions will be converted while being reinjected
- (this change) existing transactions will be converted in the background

- Correct the error message in TestOneElementProof to expect 'v' instead
of 'k'.
- The trie is updated with key "k" and value "v"; on mismatch the
expected value must be 'v'.
- Aligns the message with the actual test logic and other similar checks
in this file, reducing confusion during test failures. No behavioral
changes.

Replace time.After with a long‑lived time.Ticker in KeyStore.updater, preventing per‑iteration timer allocations and potential timer buildup.

This is a small improvement on #32656 in case Add was called with
multiple type 3 transactions, adding transactions to the pool one-by-one
as they are converted.

Announcement to peers is still done in a batch.
