   OMP Native Chat legacy parity inventory (v3)

   Invariant (verbatim, plan.md §0): "For every environment and workflow migrated from legacy OMP Chat to ACP, ACP must preserve or strengthen all existing user-visible and reliability guarantees. Workflows not yet at parity remain explicitly routed to the legacy implementation."

   v1 does not change transport ownership for already-existing legacy OMP sessions: they stay legacy, so rows that only concern adopting or handing off existing sessions have post-cutover owners and do not gate cutover (column Gates cutover). Every EG row still has exactly one owner.

   Code: Orca stablyai/orca@76d1b7b (paths relative to repo root), oh-my-pi @53f253f. v1 row ids are
   kept where the row is right; corrections are noted in the last column. Status:
   EG = existing guarantee (must be met at least as strongly before ACP is default, owned by exactly
   one issue); NS = not supported today (expansion, never a gate); MECH = legacy mechanism, not
   a user-visible guarantee (folded into the EG row named). Lines without a number were not re-read at a
   specific line and are cited by symbol. [INFERENCE] marks unverified claims the owning issue must
   confirm first.

   Legend for ACP column: = parity by existing generic code, + stronger, Δ needs work (owner
   issue), gap provider fix required (oh-my-pi issue in parentheses).

   Candidate rows reported by research but not verified (cited file missing or behavior unconfirmed);
   ORCA-7 confirms or drops them: composer drafts per tab (cited use-native-chat-composer-state.ts
   does not exist), large-paste collapse (use-native-chat-composer-handle.ts, 41 lines, behavior
   unconfirmed). Both concern the shared NativeChatComposer, so parity is expected by construction.

   ORCA-12	P-TOGL-01 (explicit routing, D2); re-verifies every gating row as the default-on gate
   ORCA-17 (C)	none owned; strengthens P-TOGL-01 for ACP chats (persisted handoff)

   Expansion (NS) rows, never gates: P-RSNG-02, P-EDIT-02 (ORCA-5); P-THNK-01 (ORCA-7); P-RSUM-03
   (ORCA-11); P-SKIL-01, P-IMAG-01 (ORCA-14). Mechanism: P-HOOK-02.

   Totals: 73 rows — 66 EG (2 marked confirm, 1 negative), 6 NS, 1 MECH. Gating: 64 EG rows gate cutover; 2 (P-DISC-01, P-DISC-02) are post-cutover (adoption). v1 had 51 rows; 22 added in v2, 0 removed, 1 re-classified (P-HOOK-02 → MECH); v3 added no rows.

   Risk-round corrections (2026-10-08)

   Rows corrected from risk-findings/: P-DISC-03 (OMP store precedence; OMP_CODING_AGENT_DIR is Orca-only), P-PLAN-01 (/plan is TUI-only over ACP), P-SCMD-02 (40 TUI-only builtins), P-STOP-01 (Stop-persistence risk resolved), P-ROPT-01 (Windows install shapes). Owners unchanged; no rows added or removed.

   v3 re-framing (user review)

   Owner changes: P-META-03 ORCA-4 → ORCA-11 (journal ring on reopen); P-RSUM-01 ORCA-4 → ORCA-11 (reattach of ACP-created chats); P-VAUL-01 ORCA-4 → ORCA-16 (single writer); P-TOGL-01 ORCA-4 → ORCA-12 (not migrated in v1, explicit routing). P-DISC-01/02 stay with ORCA-4, now post-cutover. P-QUEU-02 delta restated for the OMP steer extension. No row added or removed.

   Floor that must survive until an explicit retirement decision (D7)

   Legacy terminal/transcript chat remains the routed path for: WSL project runtimes (P-ROPT-02),
   runtime-owned SSH targets (P-ROPT-05), Windows hosts without start-time proof (P-ROPT-06),
   terminal-launched or manually started OMP (P-TOGL-01), mobile-launched OMP (caller-render downgrade,
   src/main/runtime/rpc/methods/agent-launch.ts:87-97), existing legacy OMP sessions (until adoption, ORCA-4), hosts whose omp does not satisfy
   orca-native-chat-v1 (ORCA-12), and users without the structured-chat preference
   (src/shared/structured-native-chat-launch-route.ts:77).
