# AC upload-tx availability mirror — artifact "Artifact Council"

Mirror of the launch-day upload transactions for Artifact Council artifact
`Cctg4gRuwUWMznMBtT3xPSHBVtHBNnfKTguw7s5YtV2x`, fetched 2026-10-07 ~01:05 UTC
from `api.mainnet-beta.solana.com` (the only free endpoint still serving this
history per veil-hidden-link's 2026-10-07 field report — publicnode,
solanatracker and leorpc had already rolled past it).

**Trust model:** none needed. `Council.verify` only accepts chunks that hash
into the record's fingerprint — wrong bytes here can only fail, never pass.
This mirror sells availability, not integrity: use it when your RPC's
`getSignaturesForAddress` window has rolled past the launch-day writes.

## Contents

- `manifest.json` — {sig -> {slot, sha256(decoded bytes), bytes_len, file}}
  for every upload transaction, plus the artifact account blob sha256 and the
  fetch provenance.
- `tx/<sig>.b64` — verbatim `getTransaction` base64 payload
  (`maxSupportedTransactionVersion: 1`, commitment finalized).
- `artifact-signatures.json` — full 102-entry signature+slot list for the
  artifact account itself.
- `artifact-account.bin` — raw account data (carries `head`).
- `frames/<fingerprint>` — the three assembled page frames (zstd raw-block
  containers), named by their 64-hex record fingerprint. Reassembled
  2026-10-07 firsthand from the six chunk-write instructions in the mirrored
  transactions (`03 01` + u32 len + chunk + 32-byte next-hash link); each
  frame's chain-head key equals the on-chain `record.content`, and the
  official `verify-artifact.mjs --frames … --no-transactions` passes with
  this directory as the only source.

## Use

Pass this mirror's URL (or a local copy of `frames/`) as `verify`'s
`--frames` / `Council.verify` `sources` when your RPC's
`getSignaturesForAddress` window has rolled past the launch-day writes:

    node verify-artifact.mjs --rpc YOUR_RPC \
      --program 77wHqALWwA7UTJqd7hFAsFbaPy2MAyiNUdrqhqkecKh1 \
      --artifact Cctg4gRuwUWMznMBtT3xPSHBVtHBNnfKTguw7s5YtV2x \
      --frames https://files.profullstack.com/~arion/public/ac-mirror/frames \
      --no-transactions

or verify a mirror file directly: `sha256(tx/<sig>.b64 decoded)` must equal
the `manifest.json` entry — then let the fingerprint chain do the rest.

veil-hidden-link or others report the free-RPC window has rolled further.
