feat: I3097 P04 typed hash debug transport #3101
Description
Parent feature epic: #3097. Phase P04, class patterned, owner ac-dev-webpage-ui-v5, dependency P03 (merged main required).
Situation and intended result
Carry backend-derived id_hash_debug arrays through the typed frontend contract and prove existing adapters preserve complete metadata.
Approved specification and scope

Parent plan-v3 SHA256 B86F5DC6F3813AF551FD1055953829DC0493936AD82EAE1BAF05DA8D1520351E; exact-set consensus in consensus-round3-v3.json.
Only src/shared/types.ts and src/shared/ipc.transport.test.ts. Add optional string[] siblings on AgentConfig/ProfileCellConfig. Extend existing complete legacy/canonical inbound and outbound agent/profile fixtures with independent arrays, absence and empty-array cases. Keep production ipc.ts byte-identical. No UI, coercion, hash calculation, new command, catalog field or logging.
Acceptance and verification
Array values/order/case/whitespace/empty entries preserve exactly through existing transport; malformed handling/authority remain backend-owned. Shipper runs npm run typecheck, npm test -- src/shared/ipc.transport.test.ts, npm run check:frontend-dependencies, and exact root/structural/CI gates.
After every child merges, Shipper validates the final clean synchronized main SHA with all-target cargo check and the P03 selected filter set, including all B1 filters; coordinator verifies receipts before closing epic #3097. This phase PR closes only its child. No packaged artifact/install/release/version requested.

Delivered in #3112, merged at 8118af2.
Frontend agent/profile types now expose optional id_hash_debug arrays. Existing complete transport fixtures cover legacy/canonical inputs and outbound agent/profile updates, with absent, empty, and populated arrays. Production IPC adapters are unchanged.
Independent source and proof reviews passed. Nine local Rust layering tests, formatting, and PRE/POST structural guards passed. PR CI run 39144010162 succeeded on 93573d8; all five workflow runs succeeded, with 13 successful checks and seven explained normal-tier skips. The frontend-regression job was skipped by the existing light-tier condition; local frontend checks were not run. At the user's direction, delivery used normal required CI without another toolchain installation or additional local reruns.
The merge tree exactly matches the reviewed/CI-validated feature tree ef95bd659d355049d2a7535c9576d1c3af416e2f. Local main, origin/main, and the actual origin main SHA agree; the tree is clean and the feature branch is removed. No packaged artifact was requested.
