Problem: The mainnet_compatibility.test.ts test checks that protocolContractsHash matches a hardcoded mainnet value. We missed protocol contracts while pinning protocol circuits.

Solution:

  • When pinned-protocol-contracts.tar.gz exists in the noir-contracts/ directory, the build extracts pre-compiled protocol contract artifacts and skips compiling them
  • Adds ./bootstrap.sh pin-protocol-contracts command to build protocol contracts and create the tarball

- This memory was being initialized, when anyway we zero it later. This was single-threaded, to make it worse.

parity-base 5 times, `HARDWARE_CONCURRENCY=48` on mainframe
```
HARDWARE_CONCURRENCY=48 ./bb prove --scheme ultra_honk --verifier_target noir-rollup \
  -b parity_base.json -w witness.gz -o /tmp/out --write_vk -v
```

feat: reduced hashing (#20676)
bf3191c 
We were computing contract classes left and right, making everything slow (but specially TXE). This PR makes TXE break the barrier of 1 test/s in typical cases.

In general it also makes our TS much lighter, which is specially noticeable in the browser and/or power-constrained devices.

* Refactors the contract store in PXE to eagerly compute contract classes and *store them*. We do not duplicate bytecode, but remember all the heavy hash computations to avoid repeating work
* Adds some caching to heavy artifacts to avoid expensive db serialization trips
* Precomputes contract classes values for protocol contracts, which are trusted and directly imported by PXE itself.

Token contract TXE tests on mainframe go from ~1min and totally pegging the CPU at `--test-threads 5` to ~30s and able to utilize `--test-threads 16`

feat(aztec): node enters standby mode on genesis root mismatch (#20937)
ed3f61d 
Closes A-547

## Summary

- Before calling `getL1Config()`, the node now compares its local
genesis archive root against the canonical rollup's via `archiveAt(0)`.
- If the roots don't match (e.g. during L1 contract upgrades where the
old rollup ABI is incompatible), the node enters **standby mode**
instead of crashing.
- In standby mode, a lightweight HTTP server is started for K8s liveness
probes, and the node polls every 10 minutes until a compatible rollup
becomes canonical.
- When `rollupVersion` is not explicitly configured (`undefined`), it
now falls back to `'canonical'` instead of passing `0` to the registry.

### Tested against testnet (incompatible rollup):

```
Genesis archive root: 0x2727683df35594b1f073a681532520056ca8a775398c8b5a94574c67ef1ce6de
Genesis root mismatch: expected 0x2727683df35594b1f073a681532520056ca8a775398c8b5a94574c67ef1ce6de, got 0x0ae6138310f7b877b6c68856451eddec0873fb63f9033931cedcdc46815729e1 from rollup at 0x66a41cb55f9a1e38a45a2ac8685f12a61fbfab77. Entering standby mode. Will poll every 10s for a compatible rollup...
Standby status server listening on port 8080
Still waiting. Rollup at 0x66a41cb55f9a1e38a45a2ac8685f12a61fbfab77 has genesis root 0x0ae6138310f7b877b6c68856451eddec0873fb63f9033931cedcdc46815729e1.
```

```
$ curl http://localhost:8080/status
OK
```

### Untested code paths

- Run against a compatible network: verify normal startup without
entering standby
- Upgrade the rollup after node enters standby: verify node closes the
server and exits the loop.
 

## Test plan

- Run `aztec start --node --archiver --network testnet` against an
incompatible rollup: verify standby mode with health check responding OK
- Run against a compatible network: verify normal startup without
entering standby
- Ctrl+C during standby: verify clean exit

fix(aztec-nr): account for AES PKCS#7 padding in message plaintext le…
67a908d 
…ngth (#20840)

## Summary

- Fixes index-out-of-bounds when using notes with arrays by accounting for AES PKCS#7 padding expansion (16 bytes) when computing `MESSAGE_PLAINTEXT_LEN`
- Updates `MAX_NOTE_PACKED_LEN` (9 -> 8) and `MAX_EVENT_SERIALIZED_LEN` (11 -> 10) in both Noir and TypeScript to match the corrected capacity
- Adds boundary tests for max-size and oversized messages, notes, and encryption plaintexts

Fixes F-336
Fixes #20737
@nventuro
feat: remove epk sign from message payload (#20926)
36b95fa 
This frees up one byte of capacity, but more importantly it reduces the leakage in the logs as they'll no longer contain a byte that is either 0 or 1.
@aminsammara
chore: increase mainnet local ejection threshold to 190k (#20884)
eb9bc44 
## Summary
- Increases the mainnet `AZTEC_LOCAL_EJECTION_THRESHOLD` from 162,000 TST to 190,000 TST in `network-defaults.yml`.

## Test plan
- [ ] Verify generated config files reflect the updated threshold after regeneration

@AztecBot
feat: add pinned-build support for protocol contracts in noir-contracts
db55862 
Adds a mechanism to pin protocol contract artifacts via
pinned-protocol-contracts.tar.gz, mirroring the existing pinned-build
support in noir-protocol-circuits.

When the tarball is present, the build extracts pre-compiled protocol
contract artifacts and skips their compilation. This prevents changes
to aztec-nr from altering the protocol contracts hash, which must
remain stable for mainnet compatibility.

Usage: ./bootstrap.sh pin-protocol-contracts
This builds only the protocol contracts and creates the tarball.
Commit pinned-protocol-contracts.tar.gz to freeze the artifacts.
