Review of head b2132e1a0a6ebfc0e10d900190bd8b5b1d3d66f2.
[HIGH] Keep a face-down library card's identity out of a guest's event list after it moves again in the same action. Evidence: the new get_viewer_transition_snapshot_js calls the shared filter_events_for_viewer (crates/engine-wasm/src/lib.rs:2558-2570), and P2P sends its snapshot.events to each guest (client/src/adapter/p2p-adapter.ts:2660-2666). For a Library → Exile ZoneChanged, that engine filter consults only the card's final state.objects[id].face_down (crates/engine/src/game/visibility.rs:2451-2480) and otherwise clones the event, including ZoneChangeRecord.name. Beseech the Mirror's Oracle text exiles a searched library card face down and puts it in hand if uncast. The existing production test at crates/engine/src/game/effects/search_library.rs:1954-1999 drives that chain in one SelectCards action; Exile → Hand clears face_down at crates/engine/src/game/zones.rs:372-385. The opponent's new P2P projection can therefore include the Library → face-down Exile record with the private card name. CR 406.3 says a face-down exiled card cannot be examined by other players.
Please make the shared engine event-visibility decision use event-time concealment, then add a discriminating production test that runs the complete Library → face-down Exile → Hand action through the viewer transition projection and proves the opponent's guest event list omits the private identity while the authorized viewer retains it. The new WASM test exercises a single CardDrawn; the P2P test mocks the projected events, so neither reaches this branch. #9242 has a related game-log privacy issue, but this finding concerns the separate raw event channel.
Current-head required CI is still pending. Keep this PR out of the merge queue until the privacy regression and verification are resolved.

Review of current head 2020532c91edd13d9a4b9ffc2ca8a3169d404df0.
[HIGH] The guest event projection still reveals a face-down card's identity after a same-action zone change. The new production builder passes the transition's events to filter_events_for_viewer (crates/engine-wasm/src/lib.rs:2548-2559), then P2P sends snapshot.events to the guest (client/src/adapter/p2p-adapter.ts:2660-2666). For a Library → Exile ZoneChanged, the shared engine filter consults the object's final face_down state (crates/engine/src/game/visibility.rs:2451-2485). An Exile → Hand continuation clears that flag (crates/engine/src/game/zones.rs:372-385), so the earlier Library → face-down Exile event, including its ZoneChangeRecord.name, passes to the opponent. Beseech the Mirror's verified Oracle text requires precisely that chain when the searched card is not cast; the existing production test drives the single-action path (crates/engine/src/game/effects/search_library.rs:1954-1999). CR 406.3 says cards exiled face down cannot be examined without permission.
Please repair event visibility in the shared engine authority using concealment at the time of each event, then add a production regression for Beseech's Library → face-down Exile → Hand chain that asserts the opponent's serialized event list contains no card identity. The new WASM test at crates/engine-wasm/src/lib.rs:2491-2509 exercises CardDrawn only; it does not reach this branch. The P2P transport tests mock the projection and likewise cannot prove the engine predicate. This is the same finding as my earlier review on b2132e1a; the new head leaves it unresolved. #9242 tracks a related log-channel leak separately.

Changes requested on head 8f3c17f413b26b6fd728432834f502458c1d05dd: a cross-owner face-down exile still reveals the card's identity; the new parser branch also duplicates the existing grammar.
🔴 Blocker
-
Keep the searched card's identity from its owner when only the opponent may look. At
crates/engine/src/game/visibility.rs:2558-2567, the Library → face-down ExileZoneChangedis sent toevent.ownereven when that player is absent fromHiddenSearchViewed.audience. Praetor's Grasp says, “Search target opponent's library for a card and exile it face down.” The caster searches, while the opponent owns the card; the existing searcher regression atcrates/engine/src/game/effects/search_library.rs:3282-3326confirms those are different players.ZoneChangeRecordincludes the real card name, so the opponent receives it in the raw P2P event list. The state projection already hides face-down exiled cards from an owner without a look grant (crates/engine/src/game/visibility.rs:873-925). CR 406.3 says, “Cards ‘exiled face down’ can’t be examined by any player except when instructions allow it.” Remove the owner-only bypass and use the same actual look authority as the state projection and the event's search audience. Please add a productionviewer_transition_snapshotregression for a caster searching an opponent's library: the caster retains the authorized event, while the card owner receives neither its identity nor the privateZoneChangedrecord. -
Reuse the existing nom grammar for the face-down exile follow-up. The new
matches!arm atcrates/engine/src/parser/oracle_effect/sequence.rs:8176-8189lists five complete Oracle clauses. This file already definesparse_exile_looked_at_cardat lines 973-1007; it composes the same pronoun and optionalface downaxes with nom and returnsSome(bool). Route this continuation through that parser so this class has one grammar, as required by the repository's parser convention.
🟡 Non-blocking
The current-head <!-- coverage-parse-diff --> comment is absent in the review packet. Rust/card-data CI was still pending at this review. Please ensure the eventual card-level parse diff is available and checked against the stated scope before approval.
✅ Clean
The added Beseech regression at crates/engine-wasm/src/lib.rs:2511-2573 runs the production apply path through the serialized viewer projection and discriminates the earlier same-action leak. The engine remains the event-filtering authority; P2P sends its projected result.
Recommendation: keep this PR out of the queue; address the cross-owner leak and parser reuse, then review the current-head parse diff and settled checks.
Carry the engine's latched hidden-search audience into the selection transition so a library owner cannot read a face-down exile record they were not authorized to see. Reuse the shared exile parser and surface malformed transition payloads explicitly.

Changes requested on head 3036532d48f3c994ba733f1c00cf8a4dc0bfa2ba: a replacement-choice pause can carry a face-down exile marker into a redirected battlefield entry.
🔴 Blocker
[MED] Clear destination-specific face-down intent on the resumed replacement path. Evidence: crates/engine/src/types/ability.rs:15406-15412 makes the exile marker a FaceDownProfile::vanilla_2_2(). crates/engine/src/game/zone_pipeline.rs:4468-4476 clears that profile if an executed replacement redirects the destination, but only in the synchronous ReplacementResult::Execute arm. The NeedsChoice arm at zone_pipeline.rs:4656-4689 parks the event; crates/engine/src/game/engine_replacement.rs:365-384 later sends the selected ZoneChange directly to delivery. That delivery applies any surviving profile to a battlefield entry at zone_pipeline.rs:3567-3569,3773-3776. A face-down exile redirected to the battlefield after a replacement choice can therefore acquire the marker's unrelated vanilla 2/2 characteristics. The same destination guard needs to cover both synchronous and resumed delivery. Please add a focused production regression with competing replacements that parks, selects the battlefield redirect, resumes, and verifies the resulting characteristics and event visibility. This is a latent path demonstrated by code flow; I have not established a specific printed-card pairing that exercises it today.
🟡 Verification gates
Current-head CI is terminal red: Card data reports swallowed-clause diagnostic 859 → 860 (+1), with zero engine regressions; the particular card and whether this PR caused the diagnostic remain unconfirmed. Rust lint fails the skill-doc gate self-test test_missing_self_test_suite_is_an_error because it sees priority slot 11 without a matching skill row. This PR does not change that script, skill, or oracle.rs, so the lint failure appears shared with the current base. The aggregate Rust job inherits these two failures. The required current-head card-level parse-diff comment is absent, so the parser impact cannot yet be signed off. Please resolve or attribute the diagnostic and obtain the parse-diff receipt before approval. The shared lint gate needs maintainer-side repair or a green rerun.
✅ Clean
The prior cross-owner hidden-event and parser-grammar findings are addressed on this head. The existing production WASM regression exercises the Beseech transition through the viewer projection.
Recommendation: keep #9244 out of the queue; cover the paused redirect at the shared delivery boundary, then review the parse-diff and settled required checks.

Changes requested on head c0bec10d48d29d74fe289cf13295adb9e5ec2ee4. The viewer-ID fix does not address the replacement-choice blocker from the prior review.
[MED] Clear destination-specific face-down intent when a replacement choice resumes a zone move. crates/engine/src/game/zone_pipeline.rs:4461-4477 clears the face-down exile profile after a synchronous ReplacementResult::Execute redirect, but the NeedsChoice branch parks it (:4656+). The resume path in game/engine_replacement.rs:365-384 approves and delivers the selected event without that cleanup. If the selected replacement redirects the move to Battlefield, delivery can apply the retained 2/2 profile (zone_pipeline.rs:3567-3569,3773-3776). Put the destination check at the shared post-replacement delivery boundary and add a production regression that pauses for a replacement choice, redirects, and asserts the resulting zone and characteristics. The code-path consequence is clear; reachability through a current printed-card pairing has not been established.
[LOW] Apply the new checked viewer-ID conversion to the sibling legal-actions export. crates/engine-wasm/src/lib.rs:2321-2328 still uses player_id as u8, so 256 aliases seat zero. This is host-managed input and not established as remotely reachable, but it should use the same viewer_player_id contract as the two updated snapshot exports.
Required CI and the current-head card-level parse-diff receipt were still pending/absent at review time. Please keep this PR out of the merge queue until the blocker is fixed and current-head evidence is available.

Changes requested on head 707be3f740802741e58f612a06054284f58bf0d5: a second replacement choice can still carry the face-down Exile marker into a battlefield entry.
🔴 Blocker
[MED] Preserve the original destination across every replacement pause. crates/engine/src/game/engine_replacement.rs:324-335 calls the current pending.proposed.to the intended destination. After the first choice redirects Exile to Battlefield, replacement.rs:11129-11142 runs the replacement loop again; that loop can park another applicable choice with the modified proposal (replacement.rs:10467-10488,10525-10546). On the second resume, the new comparison at engine_replacement.rs:384-388 sees Battlefield on both sides and retains the Exile-only FaceDownProfile::vanilla_2_2() (types/ability.rs:15410-15412). The card can therefore enter face down as a 2/2 despite the redirect. CR 616.1f says, “Once the chosen effect has been applied, this process is repeated (taking into account only replacement or prevention effects that would now be applicable) until there are no more left to apply.”
Clear a destination-specific profile when a replacement changes that destination, or carry the original destination through every repark. Add a production regression with two ChooseReplacement actions: redirect Exile to Battlefield first, then answer a further applicable replacement choice without changing Battlefield, and assert the card enters face up with its printed characteristics and a public zone-change event.
✅ Clean
The new zone_pipeline.rs:5645-5715 regression exercises a one-choice redirect through the real action path; the shared normalizer covers the synchronous branch. The earlier cross-owner visibility, parser grammar, and viewer-ID findings are addressed on this head.
Recommendation: keep this head out of the queue until the chained-choice path and its regression are complete.

Preserve the original face-down destination across replacement choices.
When the first replacement changes a face-down Exile ZoneChange to an intermediate zone, pipeline_loop can re-park that rewritten event for another material replacement choice. The re-parked event still carries face_down_profile: Some(_), so the next resume latches the intermediate to value. If a later replacement changes it back to Exile, normalize_face_down_profile_for_destination clears the profile. The final delivery then does not mark the object or zone-change record as face down, exposing the card to opponents.
Store the original destination on PendingReplacement and propagate it through every re-park. Add a regression covering Exile → Graveyard → Exile across two replacement choices.
