The MCP-activation stake tx built by /app/stake (init_stake_deposit, Anchor discriminator d5cbd1d000e6846a) was rejected by the gas-station validator because the allowlist only contained the four bounty-flow ixs from GHB-176/180. User-facing symptom in the browser: "Transaction rejected by gas station: disallowed_discriminator: escrow ix discriminator d5cbd1d000e6846a not in allowlist." Add the discriminator (sourced from the IDL bytes [213,203,209,208,0,230,132,106]) to ALLOWED_DISCRIMINATORS_HEX and bump the sanity-test allowlist size assertion 4 → 5. No other validator rule changes — init_stake_deposit fits the existing single-escrow-ix shape (no bundled topup, no review fee), so the rest of the pipeline already covers it.

The frontend at
/app/stakebuilds aninit_stake_depositAnchor ix and routes it through the gas station (per the existing sponsor pattern for bounty-flow ixs). The validator's allowlist was the original GHB-176/180 set of 4 bounty-flow discriminators; the GHB-188 stake ix was never added, so prod rejects every stake with:Reproduced live by Gaston during the post-merge smoke test.
