ReplicantDB Build 42 ("Restraint") release packaging, universal2 compilation, Developer ID signing, Apple notarization, and 6-host staged canary rollout for TASK-20260914-02.

Scope

• Canonical development root: rdmsm4x:~/dev/apps/replicantDB
• Isolated worktree: /Users/richh/dev/_worktrees/replicantdb-build42-rollout-20260915 (commit 076c3a8)
• Fleet deployment targets: rdmpw3265m (Intel canary), rdmbair15m5 (M5 canary), rdmpw3275m (Intel), rdmsm4x (canonical hub), rdmbair13m5, jdmbair13m5.

Changes Made

1. Version Bump: Sources/ReplicantDBCore/Version.swift build bumped from "41" to "42".
2. SIGPIPE Prevention: In Sources/ReplicantDBCore/FleetSearch.swift, added Darwin F_SETNOSIGPIPE and signal(SIGPIPE, SIG_IGN) to ProcessFleetSearchTransport preventing process termination when child processes exit during stdin writing.
3. Pipefail Hardening in build.sh: Replaced grep -q with grep ... >/dev/null in verification pipelines to avoid SIGPIPE under set -o pipefail.
4. Test Suite Verification: 1,236 / 1,236 tests executed and passing with 0 failures in 229.1s.
5. Universal2 Packaging: Executed ./build.sh producing fat binaries (x86_64 arm64) for ReplicantDB.app, replicantdb-cli, and replicantdb-mcp.
6. Code Signing & Notarization:
   • Identity: Developer ID Application: east coast science, llc (ZU2882L4HT) (1C07FCD80C36EAD5D9E3B73F7ACCCA5368DC73FB).
   • Apple Notarization: Submission IDs 698ddfa8-1eb3-404a-89ca-0c74eef578b5 (App) and fadd7ebf-b0bb-4482-b20b-9103ec72ab32 (Tools) accepted with null issues.
   • Stapled notarization ticket to ReplicantDB.app.
7. Six-Host Rollout:
   • Order: rdmpw3265m -> rdmbair15m5 -> rdmpw3275m -> rdmsm4x -> rdmbair13m5 -> jdmbair13m5.
   • Preserved active inodes by moving existing binaries to /Applications/.replicantdb-rollbacks/<TS>-build42-from-41/.
   • Verified replicantdb-cli search tax --fleet and MCP argument validation (params.arguments object decoding).
   • Ensured com.eastcoastscience.replicantDB.daemon remained completely untouched.

Verification Commands & Evidence

• swift test: 1,236 executed, 0 failures.
• lipo -archs dist/ReplicantDB.app/Contents/MacOS/ReplicantDB dist/replicantdb-cli dist/replicantdb-mcp: x86_64 arm64 on all targets.
• replicantdb-cli search tax --fleet --json: 6/6 hosts answered via cli in 0.94s.
• TASK-20260914-02: Resolved on canonical rdmsm4x.
