ci: pass deployer pubkey as buffer authority for devnet#73
Merged
Conversation
The write-program-buffer action runs `solana program set-buffer-authority` when the program already exists on-chain, regardless of whether a transfer is actually intended. We were passing an empty `buffer-authority-address` on devnet, which the CLI rejects with "The argument '--new-buffer-authority <NEW_BUFFER_AUTHORITY>' requires a value but none was supplied" and retries up to 50 times before failing. Derive the deployer pubkey from the materialized keypair and use it as the buffer authority on devnet. This is a no-op transfer (deployer keeps authority) and satisfies the action's requirement. Mainnet still uses SQUADS_VAULT.

The write-metadata-buffer and verify-build (mainnet/use-squads) actions
take `keypair` as the keypair file content, not a path — same pattern as
the devnet sub-actions fixed previously. Pass `${{ env.DEPLOYER_KEYPAIR }}`
directly so a future mainnet release does not fail with "Input must be a
JSON array".
The Squads upgrade-proposal action is left as-is (still consumes
/tmp/deployer.json), so the materialize/cleanup steps remain.

Summary
buffer-authority-addressfor devnet releases.Write program bufferon devnet, which was retrying 50× then failing.Root Cause
solana-developers/github-actions/write-program-bufferruns an internalTransfer buffer authoritystep wheneversteps.check-program.outputs.exists == 'true':We were passing an empty
buffer-authority-addresson devnet, so the CLI rejected the call:The action has no flag to skip this step, so we satisfy it by transferring authority to the deployer itself (effective no-op).
