feat(engine,client): show the marker token a face-down permanent was made with (#7532) - #7535
Conversation
…made with (phase-rs#7532) CR 708.2a gives every face-down permanent identical characteristics, so a manifested 2/2, a morphed 2/2 and a cloaked 2/2 were indistinguishable on the board — all three rendered the same generic card back. Paper play does not allow that. The 2024-09-20 Duskmourn rulings require it: "You must ensure that your face-down spells and permanents can be easily differentiated from each other. … The order in which they entered should remain clear, as well as what ability caused them to be face down. (This includes manifest, disguise, cloak, morph, and a few older effects that turn cards face down.)" which is why Wizards prints a marker token for each family. Engine: `FaceDownCause` records which keyword action put the permanent face down — CR 701.40a/701.62a manifest, CR 702.36a morph, CR 701.58a cloak, CR 702.166a disguise, plus `TurnedFaceDown` for the Ixidron class that has no keyword action at all. The variants follow the RULES, not the markers: morph and megamorph are one ability with one token, while cloak and disguise are two different rules that share a token. Collapsing them would put a display decision in the engine. The cause rides `FaceDownProfile`, which is what survives a CR 616.1 entry pause, and is stamped by the single face-down entry helper (`zone_pipeline::apply_face_down_entry_profile`). The two constructors carry the characteristics-defining default; the face-down CAST path restates its own cause via `caused_by` instead of leaving the reader to infer morph-vs-manifest from the ward. No game rule reads the field. It is deliberately NOT cleared on turning face up: a dozen unrelated paths clear `face_down`, and requiring each to remember a second field is how a stale marker would eventually ship. Readers gate on `face_down`; both client call sites do, and `faceDownMarkerRef` enforces it. Client: `faceDownMarkerRef` maps the four causes onto three printings, all three of which are already in the shipped `scryfall-token-images.json` index, so no data change is needed. `CardImage` and `ArtCropCard` feed the marker through the existing `tokenImageRef` path; `CARD_BACK_URL` stays the fallback for an unknown cause, the marker-less `TurnedFaceDown` cause, and a lookup that fails. Not covered: the morph and disguise causes have no runtime test. Both are set by `face_down_cast_profile` on the face-down CAST path, which needs a card with the keyword and a {3} payment to exercise; the manifest and cloak causes are covered end to end, and the cast path's two lines are a straight-line restatement of the same enum.

Preserve TurnFaceDown causes when parsing face-down profiles.
FaceDownProfileSpec replaces the full profile with a parser result whose cause is hard-coded to Manifest. The TurnFaceDown parser also seeds vanilla_2_2() with that cause. This records FaceDownCause::Manifest and can render a manifest marker for a turn-face-down effect.
Seed TurnFaceDown with FaceDownCause::TurnedFaceDown, then preserve that cause when applying the profile continuation. Add a regression test for a profiled TurnFaceDown effect.

Changes requested — the marker provenance and fallback contract are incomplete on this head.
🔴 Blocker
[HIGH] TurnFaceDown never stamps its own provenance. Evidence: crates/engine/src/game/effects/turn_face_down.rs:24-75 applies the supplied profile at line 72 and stores only back_face, whereas the zone-entry authority stamps obj.face_down_cause = Some(profile.cause) at crates/engine/src/game/zone_pipeline.rs:3170-3194. Why it matters: a generic turn-down has None (or can retain stale state) instead of TurnedFaceDown, so the display reports the wrong marker source. Suggested fix: set the resolved profile cause to FaceDownCause::TurnedFaceDown in this resolver before applying it, and cover both the default and profiled (Cyber Conversion) paths through the production pipeline.
[HIGH] A failed face-down marker URL does not fall back to the card back. Evidence: client/src/components/card/CardImage.tsx:97,131-153 suppresses the regular fallback whenever faceDown is true, then keeps rendering the failed marker URL after onError; client/src/components/card/ArtCropCard.tsx:124,199-209 instead replaces it with CardArtFallback. Why it matters: the two board renderers violate the intended card-back fallback and can show a broken image or non-card-back tile. Suggested fix: on a marker-image error, switch both paths to CARD_BACK_URL and add render tests that dispatch an error for a resolved marker URL.
[HIGH] The new morph/disguise CR citations are false. Evidence: crates/engine/src/types/ability.rs:11645-11663 cites morph as CR 702.36 and disguise as CR 702.166; the checked local docs/MagicCompRules.txt defines 702.36 as Fear and 702.166 as Bargain, while 702.37 is Morph and 702.168 is Disguise. Why it matters: the public engine annotation points reviewers and future maintainers to unrelated rules. Suggested fix: replace the references with CR 702.37a/b for morph/megamorph and CR 702.168a for disguise.
[HIGH] The integration coverage does not exercise the paths this metadata claims to cover. Evidence: crates/engine/tests/integration/face_down_cause_marker.rs:73-113 reaches manifest/manifest dread, cloak, and face-up only; it has no generic TurnFaceDown scenario or face-down morph/disguise cast. Why it matters: the missing resolver stamp and the two keyword casting provenance paths can regress while this suite stays green. Suggested fix: add reach-guarded scenario-runner tests for generic turn-down plus morph and disguise casts, asserting both that the permanent is face down and that its recorded cause is correct.
✅ Scope evidence
The current-head parse-diff receipt (<!-- coverage-parse-diff -->) is bound to 83933ddb7dfa8ae554667724c541da5c59d3aaf8 and reports the expected six face_down_profile field changes; it does not replace runtime provenance coverage. Aggregate CI is red solely because the Tauri child was cancelled; all other split Rust results in that aggregate were successful, so that is not the source blocker here.
Recommendation: request changes for the four bounded fixes above, then re-run the current-head review.
…fix the CR numbers
Addresses the four review findings on `712a0074d`.
1. `effects::turn_face_down` never stamped a cause: it applies the profile
directly rather than through the zone-entry authority, so a generic turn-down
(Ixidron) and its profiled sibling (Cyber Conversion) both left the field
`None` — or, on a re-turn, stale. The resolver now restates
`FaceDownCause::TurnedFaceDown` on the resolved profile before applying it, so
the authored-profile path cannot inherit the manifest default the vanilla
constructor carries, and stamps the object itself.
2. A face-down marker URL that fails to load now falls back to `CARD_BACK_URL`
in BOTH renderers. `CardImage` kept rendering the failed URL (its
`showArtFallback` is gated on `!faceDown`); `ArtCropCard` swapped in the
artless text tile, which is for face-UP cards with no printing. A face-down
permanent has the card back to fall back to and must use it.
3. The morph and disguise CR numbers were wrong, and existed: CR 702.36 is Fear
and CR 702.166 is Bargain. Corrected to CR 702.37a/702.37b (morph/megamorph)
and CR 702.168a (disguise), verified against `docs/MagicCompRules.txt` lines
4288/4290/4292 and 5233/5235.
4. Coverage for the paths the metadata claims:
* `a_morph_cast_records_the_morph_cause` and
`a_disguise_cast_records_the_disguise_cause` drive a real face-down cast
(keyword + the fixed {3}) through the scenario runner and reach-guard on the
permanent having entered face down.
* `a_generic_turn_face_down_records_its_own_cause` and
`a_profiled_turn_face_down_records_its_own_cause` cover the default and the
Cyber Conversion profile through the production spell path.
* `CardImage.test.tsx` renders a resolved marker, dispatches an `error` on it
and asserts the card back, and pins the marker-less `TurnedFaceDown` cause
at the card back.

All four findings accepted and fixed at 1 — 2 — marker fallback. Both renderers now fall back to 3 — the CR numbers. Correct and my fault. CR 702.36 is Fear, CR 702.166 is Bargain; both exist, which is exactly why a bare existence check would not have caught it. Now CR 702.37a/702.37b and CR 702.168a, read against 4 — the two cast paths. Unrelated: the red check on the previous head was the Tauri compile job being CANCELLED ( Local: fmt clean, clippy clean, 19,450 lib + 5,249 integration, 250 frontend component tests. |

Prove that the profiled effect reached the authored profile path.
Both the generic and profiled effects must record TurnedFaceDown. If parsing drops “It’s a 2/2 Cyberman artifact creature,” this test still passes with the default profile. Also assert the resulting permanent has the Artifact core type and Cyberman subtype.
As per path instructions: “A test must exercise the FAILURE path the fix prevents and drive the engine through its production pipeline.”

Approved for merge queue at 5cc4f9837ee140cd367393258ebbc56cfb548bc9.
Current CI is green, the parse-diff sticky is SHA-bound and limited to the six expected face_down_profile deltas, and CodeRabbit's review of the maintainer test-fixup reports no actionable findings. The earlier feedback is either fixed on this head or superseded: TurnFaceDown restates TurnedFaceDown at its resolver seam; both image renderers use the card back for a missing or failed marker; the profile/cast runtime paths retain reach guards.
…rs#7541) (phase-rs#7544) * fix(engine): snapshot the real face on a debug turn-face-down (phase-rs#7541) The face-down half of the arm phase-rs#7540 repaired. `face_down: Some(true)` set the flag and nothing else, so the permanent kept its name, printed P/T and abilities while claiming to be face down — and `back_face` stayed empty, which meant the repaired face-up path could never bring it back. CR 708.2a: a permanent turned face down "becomes a 2/2 face-down creature with no text, no name, no subtypes, and no mana cost". Those are characteristics to install over a snapshot, not a flag to raise. Routes through `zone_pipeline::apply_face_down_entry_profile`, the authority the manifest, cloak and face-down-cast paths all run through, stamped `FaceDownCause::TurnedFaceDown` so the marker art added by phase-rs#7535 names the right keyword action. CR 708.2b — "A face-down permanent can't be turned face down … nothing happens and that effect doesn't change any of its characteristics" — falls out of the `was_face_down` guard rather than being re-asserted. A row pins it; that row is a pin, not a discriminator, and says so. Counter-probe: with the arm disabled, the round-trip row fails on `left: "Open Bear" right: ""`. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(PR-7544): route the debug turn-face-down through the direct-turn authority The sandbox arm ran `zone_pipeline::apply_face_down_entry_profile`, which serves battlefield ENTRY: it snapshots the live face, so a permanent carrying continuous modifications came back from the round trip with them baked into its base (and then re-applied on top); it overwrote a flipped permanent's stashed normal half; and it accepted double-faced and melded permanents. The eligible authority already existed in the Ixidron / Cyber Conversion resolver. Its per-object body is now extracted as `effects::turn_face_down::turn_permanent_face_down` — base-face snapshot, flip-stash preservation, CR 712.16 / CR 730.2j refusal, cause stamping, `TurnedFaceDown` event, layer re-derive — shared by the resolver loop and the sandbox arm, which converts a refusal into an error (mirroring the face-up arm) instead of staying silent. Three discriminating rows: a +1/+1-countered 4/4 round-trips to base 4/4 with the counter applying exactly once; a flipped permanent's stashed normal half survives; a melded permanent is refused unchanged. All three fail on the pre-fix entry-profile path; the four existing rows and the resolver's seven unit rows stay green either way.

…phase-rs#7549) (phase-rs#7550) * fix(client): let a face-down marker request pass the empty-name guard (phase-rs#7549) The phase-rs#7535 marker request deliberately carries no card name and no oracle id — only `tokenImageRef` names the printing. `useCardImage` short- circuited on exactly that shape (effect guard AND first-render snapshot), so `fetchTokenImageByRef` was unreachable and every face-down permanent fell back to the generic card back: the merged marker feature never worked in the live client. Both guards now let a present `tokenImageRef` through. The regression exercises the REAL hook (service layer stubbed at fetch, hook logic live) — the shipped component tests stubbed the hook itself, which is how a dead feature stayed green. Red-first verified: the row fails on the pre-fix guards, passes with them widened. Found by live playtest (the marker art data was present and correct all along — `scryfall-token-images.json` carries all three oracle keys with usable URLs). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(client): treat a token ref with no ids as no ref (phase-rs#7549) CodeRabbit review on phase-rs#7550: a TokenImageRef whose scryfall_id AND scryfall_oracle_id are both empty held the widened empty-name guards open, so a request with no name, no oracle id and an unresolvable ref fell through to fetchTokenImageUrl("") — a `t:token !""` junk search. The guards now key on resolvableTokenImageRef (either id non-empty); our face-down markers carry only an oracle id (empty scryfall_id) and keep passing. Red-first: the new real-hook row (empty-ids ref -> no fetch at all, src null, not loading) fails on the old guards and passes now; the phase-rs#7549 marker row and the unusable-ref name-fallback row are unchanged.

… the preview (phase-rs#7547) (phase-rs#7551) * fix(client): back every face-down tile with its cause marker; peek in the preview (phase-rs#7547) The battlefield tile of the viewer's OWN face-down permanent tried to render the real face — which the engine correctly blanks (CR 708.2a) — and fell back to the generic card back with a spurious DFC badge, since the stored real face in `back_face` satisfied `hasOtherPrintedFace`. The phase-rs#7535 marker only ever engaged for opponents. Now the tile always shows the cause marker, exactly as the physical card lies in paper: `renderCardBack` keys on `face_down` alone in the three battlefield renderers (PermanentCard, ArtCropCard, AttachmentFan), the tile's name bar reads the marker's printed name (Morph / Manifest / A Mysterious Creature) instead of "Face-down card", and `hasOtherPrintedFace` excludes face-down permanents (CR 712.16: a double-faced permanent can't be face down — that slot is the stored real face, not another printed face). The controller's peek moves where the rules put it (CR 708.5): the hover preview resolves the STORED face for `display_visible_to_viewer` objects on any hovered face index. An opponent hovering a face-down permanent now gets the cause marker full size — the mechanic's reminder text is exactly what they may know; before, they got nothing. The owner-side marker companion was cut on playtest feedback: it covered the real card's rules text and the controller knows the mechanic. Three rows rewritten to the new contract, three added (own-tile marker + no DFC badge; owner peek; opponent marker preview). Counter-probe: with the viewer-gate restored on the tile, the own-tile row fails. Runtime marker LOADING is phase-rs#7549's separate fix — without it these tiles fall back to the generic card back (name label still correct). Playtested live by the human half of this account (both preview modes). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(client): preview a markerless face-down permanent as the generic back (phase-rs#7547) CodeRabbit review on phase-rs#7551: an opponent's face-down permanent whose cause has no marker printing (absent cause from an older save, or the Ixidron class — TurnedFaceDown) got NO preview at all: faceDownMarkerName returned null, so CardPreview received no cardName and rendered nothing. The hover now answers with the plain card back — it reveals nothing (CR 708.2a: turned face down by a spell or ability means a 2/2 with no text and no name) — captioned with the generic face-down label. Every art lookup in that branch is suppressed so neither the label nor a blanked ref can leak into a network search. Red-first: two preview rows (unknown cause; TurnedFaceDown) fail before and pass now; the former "never previews (hidden information)" row's assertion moved from "renders nothing" to "renders the back, never the name" — the hidden-information guarantee it pinned is unchanged. Playtested locally (Rule 0): marker previews and owner peeks unchanged. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(client): keep hidden-zone face-down cards previewless (phase-rs#7547) CI on 90ae817: the hideaway regression (issue phase-rs#2889, issue_2889_hideaway_exile_visibility.test.tsx) failed — the generic card-back preview fallback applied to EVERY hidden face-down object, so a face-down card in hideaway EXILE started rendering a preview where that row pins none. The generic-back path is now gated on zone === "Battlefield", where CR 708.2a gives the object public characteristics (a blank 2/2) the back can stand in for. A face-down card in a hidden zone has no public characteristics at all and keeps rendering no preview — both the GameCardPreview label fallback and CardPreview's genericFaceDownBack carry the gate, so neither a label nor a lookup fires for hidden zones. Full client suite run locally this time: 2949 tests green, the hideaway row red-first against the unscoped fallback. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(client): mobile preview consumes the parent's resolved art — no second lookup (phase-rs#7547) PR 7551 review [HIGH]: MobilePreviewOverlay ran its own second useCardImage(cardName, { oracleId: obj?.printed_ref?.oracle_id, ... }), bypassing the resolved markerIsPrimary / genericFaceDownBack gating. On a wire that carries a hidden face-down permanent's printed_ref, the mobile path fetches and renders the REAL printing — hidden information. (The engine clears the live printed_ref on BOTH face-down paths today — morph.rs pins it and effects/turn_face_down.rs shares the same authority — so the current wire ships none; the display bypass is fixed regardless, and with it mobile's junk name-search for marker captions.) The overlay now receives the parent's RESOLVED art state ({src, isLoading, isRotated, isFlip} — marker, generic back, or owner peek already applied) and runs no lookup of its own; its obj/faceIndex/ sourcePrinting inputs are gone with it. Red-first (CardPreview.mobileFaceDown.test.tsx, mobile branch forced): a Morph with a poisoned printed_ref rendered "secret-oracle-id.png" and a markerless face-down rendered the secret instead of the card back; both rows now assert the marker ref / CARD_BACK_URL, that no rendered src carries the secret, and that NO useCardImage call receives the hidden oracle id or face name. Full client suite: 2951 green. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> --------- Co-authored-by: Claude Fable 5 <noreply@anthropic.com>

Closes #7532.
Defect
CR 708.2a gives every face-down permanent identical characteristics, so a manifested 2/2, a morphed 2/2 and a cloaked 2/2 were indistinguishable on the board — all three rendered the same generic card back (
CardImageandArtCropCardshort-circuit the whole image pipeline onfaceDownand renderCARD_BACK_URL).Paper play does not allow that. The Duskmourn rulings of 2024-09-20:
which is why Wizards prints a marker token for each family.
Engine
FaceDownCauserecords which keyword action put the permanent face down: CR 701.40a / CR 701.62a manifest, CR 702.36a morph, CR 701.58a cloak, CR 702.166a disguise, plusTurnedFaceDownfor the Ixidron class that has no keyword action at all.The variants follow the rules, not the markers: morph and megamorph are one ability with one printed token, while cloak and disguise are two different rules that share a token. Collapsing them here would put a display decision inside the engine — mapping four causes onto three markers is the client's job.
The cause rides
FaceDownProfile, which is what survives a CR 616.1 entry pause, and is stamped by the single face-down entry helper (zone_pipeline::apply_face_down_entry_profile). The two constructors carry the characteristics-defining default; the face-down cast path restates its own cause viacaused_byrather than leaving the reader to infer morph-vs-manifest from the ward. No game rule reads the field.It is deliberately not cleared on turning face up: a dozen unrelated paths clear
face_down, and requiring each to remember a second field is how a stale marker would eventually ship. Readers gate onface_down— both client call sites do, andfaceDownMarkerRefenforces it.Client
faceDownMarkerRefmaps the four causes onto three printings. All three are already in the shippedscryfall-token-images.jsonindex (oracle:…:morph,oracle:…:manifest,oracle:…:a mysterious creature), so no data change is needed.CardImageandArtCropCardfeed the marker through the existingtokenImageRefpath;CARD_BACK_URLstays the fallback for an unknown cause, for the marker-lessTurnedFaceDowncause, and for a lookup that fails.No hidden information is exposed: which effect turned a permanent face down is public — every player watched it happen — and the ruling above requires the physical game to make it visible. The card's identity stays in
back_faceand is untouched.Coverage
