feat(SEV-046): CD pipeline for devnet + mainnet program deploys (#272)

[alrimarleskovar]

TL;DR

Pass-12 attack on docs/operations/mainnet-canary-plan.md §3.3 (item: "CD pipeline approved + tested — staging deploy via #272 rehearsed at least once"). Closes the scaffolding half of #272 — workflow files, mainnet deploy script, and ceremony docs. Closing the execution half (3× clean rehearsal on devnet + one mainnet dry-run) is operator-gated; this PR is the lift to make that possible.

Same shape as PR #381 (Squads ceremony template, Immunefi package, observability spec): code + docs sandbox-completable, execution gated on humans + secrets.

Finding (SEV-046, Medium)

Three concrete risks the canary-plan flagged:

1. Reproducibility drift — operator's WSL/macOS toolchain doesn't match OtterSec verify-build's runner. PR feat(toolchain): Agave 2.x migration (#230) — BLOCKED on upstream mpl-core #319 (Agave migration) historically burned ~1d/cycle on version mismatches.
2. No audit trail — tx signatures lived only in the operator's terminal scrollback.
3. No rehearsed mainnet ceremony — Squads + hardware scoped from scratch each time.

Also surfaced: scripts/devnet/deploy.ts:53 told operators to "use scripts/mainnet/deploy.ts" but that file did not exist.

docs/operations/cd-pipeline.md (NEW)	200	Topology + one-time setup + rehearsal protocol
docs/operations/mainnet-canary-plan.md	+1 line	§3.3 checkbox reference to new doc
package.json	+1 script	mainnet:deploy
docs/security/internal-audit-findings.md	row	SEV-046 (Medium, Closed) + summary table updates
CHANGELOG.md	+1 entry	Pass-12 wave description

Workflow design highlights

devnet-deploy.yml

• Trigger: tag devnet-deploy-v* OR workflow_dispatch with reason input (free-text, captured in audit log).
• Toolchain: Agave 3.0.0 + Anchor 0.30.1 (mirrors working anchor · build lane proven by SEV-012 / PR feat(SEV-012, partial): re-attempt bankrun-no-mpl-core CI lane (#381 fix) #385).
• DEVNET_DEPLOYER_KEYPAIR secret (base64 JSON) restored to disk + balance ≥ 5 SOL gate.
• anchor keys sync is allowed to auto-sync — devnet IDs are disposable.
• Artifact: config/program-ids.devnet.json with 90-day retention.
• Keypair cleanup if: always().

mainnet-deploy.yml

• Trigger: tag mainnet-deploy-v* ONLY — no workflow_dispatch. Every mainnet run must trace to a signed git tag.
• Two jobs:
  • preflight (no approval, read-only): mainnet_hardening_check vs live cluster + verifies anchor keys sync would be a no-op (mainnet IDs are permanent, refuses on drift).
  • deploy (environment: mainnet → GitHub required-reviewers gate): same toolchain, same guards from scripts/mainnet/deploy.ts, sealed anchor build --no-idl (no auto-sync).
• Artifact: 365-day retention (longer than devnet — mainnet deploys are audit anchors).
• Secrets scoped to the mainnet environment: MAINNET_DEPLOYER_KEYPAIR, EXPECTED_AUTHORITY, EXPECTED_TREASURY, EXPECTED_APPROVED_ADAPTER, MAINNET_CORE_PROGRAM_ID.

scripts/mainnet/deploy.ts

Refuses to start unless ALL of:

• SOLANA_CLUSTER=mainnet-beta
• MAINNET_DEPLOY_CONFIRM=I-UNDERSTAND-THIS-IS-MAINNET sentinel
• MAINNET_DEPLOYER_KEYPAIR path exists
• All 3 EXPECTED_* env vars set

Then runs mainnet_hardening_check (if ROUNDFI_CORE_PROGRAM_ID is set — defense-in-depth on top of preflight job), echoes canary-plan reminders, sleeps 10s (last-chance Ctrl-C window for manual invocation), proceeds with build + deploy.

Test plan

• pnpm typecheck green
• pnpm lint green
• CI: all standard lanes stay green (anchor, js, deny, audit, freeze-enforcement, bankrun-no-mpl-core)
• Out-of-sandbox: operator runs devnet-deploy.yml 3× clean to satisfy the canary-plan rehearsal item
• Out-of-sandbox: operator configures mainnet GitHub environment with required reviewers + 5 secrets

What this PR does NOT do

• Run the workflows. Both need repo-level secrets configured (DEVNET_DEPLOYER_KEYPAIR etc.), and mainnet needs the mainnet environment created in repo Settings. Sandbox can't do either.
• Fund the deployer keypairs. Needs SOL on devnet (faucet) and mainnet (real).
• OtterSec verify-build automation. Still manual post-deploy. Will be added when the formal OtterSec engagement starts.
• Squads multisig integration in the deploy itself. Squads ceremony rotates upgrade authority POST-deploy; documented in cd-pipeline.md under follow-ups.

Freeze status

Permitted under FREEZE.md:

Bug fixes that close a tracked SEV — SEV-046 added in this PR.

Single concern (CD pipeline). No on-chain code changed. No effect on user-facing behavior until operator triggers a workflow.

Recommended merge method

Merge commit — single self-contained scaffolding bundle.
