Changes requested — the current head has three correctness gaps in the chain-referent contract.
🔴 Blocker
-
crates/engine/src/parser/oracle_effect/lower.rs:2696still searches gated publishers withis_token_creating_effect, whilecrates/engine/src/parser/oracle_effect/mod.rs:20970seedsLastCreatedwith the broaderpublishes_chain_created_referent. A gated Manifest, Manifest Dread, or Cloak can therefore seedLastCreatedyet remain aSequentialSibling; when the gate is false, that sibling may consult the game-lifetimelast_created_token_idsledger described atlower.rs:2657, binding a stale earlier referent. Use one common producer predicate for both seeding and gated relinking, and add a gated face-down-producer regression. -
crates/engine/src/game/morph.rs:557publishes only the synchronousDoneresult; its own:561comment confirms that the parked-entry resume is unwired. The two-card Manifest Dread arm has the same done-only publication atcrates/engine/src/game/engine_resolution_choices.rs:1826, while the replacement resume delivers the parked zone change atcrates/engine/src/game/engine_replacement.rs:261without publishing this chain referent. An as-enters/replacement pause can thus resume with no current target (or a stale one). Carry a typed post-delivery publisher through the pause/resume authority and cover the parked path before allowing its continuation to readLastCreated. -
crates/engine/src/parser/oracle_effect/imperative.rs:6051passes every unresolved recipient intocounter_anaphor_created_token_binding, andcrates/engine/src/parser/oracle_effect/counter.rs:93accepts bareitunder the weaker token-only gate. That changes bare-pronoun attachment behavior after the existing subject-based branch rejects it, contrary to the precedingimperative.rs:6047contract. Keep the fallback to demonstrative/definite forms (or prove and document the intended bare-itbehavior) and add a regression.
The existing synchronous tests and green checks do not exercise these gated or parked continuations. The CodeRabbit findings on the same current head independently identify the first two gaps; I verified all three against afbbc34c2d14b7415bac7b3fd711c04857be4338.
Recommendation: request-changes — redesign the parser/runtime contract around a shared producer predicate and a post-delivery referent publisher, then add gated, paused-entry, and bare-pronoun regression coverage.

All three findings accepted and fixed at 1 — one producer predicate. 2 — one publish site. The publish moved out of 3 — demonstratives only. The attach recipient now calls Still not proven, and I would rather say so than imply otherwise: no test drives a real CR 616.1 entry pause end to end. The parked arm is covered by sharing the publish line, and the zone-gate tests pin which callers reach it. Local: fmt clean, clippy clean, 19,452 lib + 5,247 integration tests pass. |

Changes requested — this head fixes the original parser split, but the runtime publisher is still at the wrong seam and the continuation test does not prove the stale-reference failure path.
🔴 Blocker
-
crates/engine/src/game/zone_pipeline.rs:3192-3213publishes every face-down battlefield entry intolast_created_token_ids. That helper is shared by the ordinary face-down special action (crates/engine/src/game/morph.rs:290-299) and the genericZoneMoveRequest::face_downdelivery path (zone_pipeline.rs:3695-3712), while the parser's admission authority deliberately names onlyManifest,ManifestDread, andCloakas chain-referent producers (crates/engine/src/parser/oracle_effect/lower.rs:2649-2654). A zone check cannot establish that this entry was the designated producer in the current instruction chain; it can overwrite the game-lifetimeLastCreatedledger for an unrelated face-down entry. Carry a typed producer/referent intent on the relevant zone/replacement delivery contract, and publish only when that intent reaches successful delivery. -
crates/engine/tests/integration/manifest_dread_that_creature_anaphor.rs:118-129begins with no prior referent, so it cannot detect retention of an oldlast_created_token_idsvalue. The gated case at:244-281only examines the parsedAbilityDefinition; it never executes accept and decline throughGameRunner. Add a production Manifest Dread continuation scenario that first creates a prior referent, forces the paused/replacement path, and proves both accepted delivery attaches to the newly manifested object and declined/empty delivery does not attach to the prior one. The current-head CodeRabbit finding atdiscussion_r3806360347independently identifies the same missing runtime proof.
🟡 Non-blocking
crates/engine/src/parser/oracle_effect/imperative.rs:6056-6066still has the CodeRabbit-reported duplicated explanatory comment. It does not affect the requested-changes decision.
Recommendation: request changes — make the producer identity explicit through the delivery/resume authority, then add the stale-prior and accept/decline paused-continuation regressions before re-review.
…eature (phase-rs#7531) CR 608.2c + CR 701.40a + CR 701.58a + CR 701.62a. A clause that puts a face-down permanent onto the battlefield produces exactly one new permanent and declares no target, so a following "it" / "that creature" has exactly one possible referent — the same situation as a token producer. The chain-referent machinery only recognised TOKEN producers, so the anaphor fell through: Conductive Machete "manifest dread, then attach this Equipment to that creature" -> Attach { ParentTarget }, and ManifestDread has no targets, so the attach was a silent no-op. Formless Nurturing "Manifest the top card of your library, then put a +1/+1 counter on it" -> PutCounter { SelfRef }, i.e. the SORCERY, so the counter went nowhere. Three parts, all on existing authorities: * `publishes_chain_created_referent` (lower.rs) widens the chain-referent predicate from "created a token" to "produced a permanent", adding Manifest, ManifestDread and Cloak next to Populate/Token/CopyTokenOf. * `parse_attach_recipient` (imperative.rs) routes a DEMONSTRATIVE recipient through `counter_anaphor_created_token_binding` — the authority the counter path already uses for the identical anaphor — so the two consumers cannot disagree about what "that creature" means. The bare "it" branch keeps its own wider gate untouched. * `morph::publish_face_down_entry_referent` records the face-down entrant in the same referent slot the token producer writes. `manifest_card` is the one runtime producer for manifest / manifest dread / cloak; manifest dread's two-card arm moves the chosen card from its own continuation, so it publishes there too. Class, measured by parsing all 35,399 distinct cards in `client/public/card-data.json` with and without the change: exactly 7 cards change parse, and every change is a fix. | card | before | after | |---|---|---| | Conductive Machete | Attach { ParentTarget } | Attach { LastCreated } | | Cursed Windbreaker | Attach { ParentTarget } | Attach { LastCreated } | | Dissection Tools | Attach { ParentTarget } | Attach { LastCreated } | | Killer's Mask | Attach { ParentTarget } | Attach { LastCreated } | | Fierce Invocation | PutCounter { SelfRef } | PutCounter { LastCreated } | | Formless Nurturing | PutCounter { SelfRef } | PutCounter { LastCreated } | | Wildcall | PutCounter { SelfRef } | PutCounter { LastCreated } | Counter-probe: with the demonstrative branch removed, `the_equipment_attaches_to_the_creature_manifest_dread_produced` fails with `attached_to: None` while the token control test stays green. Not covered: * Cryptic Coat ("cloak the top card of your library, then attach this Equipment to **it**") still lowers to `Attach { SelfRef }`. The bare object pronoun runs through `attach_neuter_recipient_resolves_via_subject`, a deliberately wider gate this change does not touch. * Weight Room, Slimy Aquarium and Experimental Lab ("When you unlock this door, manifest dread, then put N +1/+1 counters on that creature") still bind `TriggeringSource` — the counter path's trigger-subject gate re-anchors the demonstrative to the Room, which can never be the creature. That gate is a separate question with its own blast radius. * Valgavoth's Onslaught's PLURAL anaphor ("each of those creatures") reads the chain tracked set, not this single-referent slot — the `ManifestDread` row of phase-rs#7467. Publishing that set is measured NOT to be sufficient on its own: the ability's `repeat_for X` wraps the follow-up counter clause, so with X = 2 the first manifested creature ends up with 4 counters instead of 2. Reported separately rather than half-fixed here. * Goblin Plate Mail ("amass Goblins 1, then attach this Equipment to the amassed Army") lowers to `Attach { Any }` — a different anaphor with its own producer.

…s only Addresses the three review findings on `afbbc34c2`. 1. `relink_gated_token_referent_consumers` and `clone_would_transplant_gated_referent` searched publishers with `is_token_creating_effect` while the seeder used the wider `publishes_chain_created_referent`. A gated Manifest/ManifestDread/Cloak could therefore seed `LastCreated` and still leave its consumer a `SequentialSibling` that reads the game-lifetime ledger when the gate is false. All three passes now ask the one predicate. 2. The referent publish moves out of `morph::manifest_card` and the manifest dread continuation into `zone_pipeline::apply_face_down_entry_profile` — the single helper the synchronous entry, the two-card continuation AND the CR 616.1 parked-entry resume all run. It is gated on the object's ZONE rather than on the caller, because `casting.rs` runs the same helper for a face-down CAST, where the object is on the stack and has produced no permanent to name. 3. The attach recipient now calls a DEMONSTRATIVE-only entry point (`chain_created_demonstrative_binding`) instead of the composed counter binding, so bare "it" keeps the binding its own subject-aware authority gives it. `counter_anaphor_created_token_binding` composes the same helper for the counter path, so the two forms still cannot disagree about "that creature". Regressions added: * `a_battlefield_face_down_entry_publishes_the_chain_referent` / `a_face_down_cast_on_the_stack_publishes_nothing` — the zone gate, in both directions. * `a_gated_face_down_producer_keeps_its_consumer_under_the_gate` — a gated manifest dread's attach stays inside the gated instruction and carries the same condition. * `the_bare_pronoun_recipient_is_left_to_its_own_authority` — "…then attach this Equipment to it" is unchanged (`SelfRef`, the Cryptic Coat shape). Still not proven: no test drives a real CR 616.1 entry pause end to end. The parked arm is covered by sharing the publish line with the synchronous arm, and the zone-gate tests pin which callers publish; the two-card continuation is covered end to end by the existing integration test. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…s#7531) The publish moved off the shared CR 708.3 characteristics helper and onto the entry request, where the question can actually be answered. The old placement asked the ENTRANT ("is it on the battlefield?"). That cannot establish that this entry was the producer the sentence refers back to: `apply_face_down_entry_profile` is reached by the ordinary face-down special action, by the generic `ZoneMoveRequest::face_down` delivery and by two cast SIMULATIONS in `casting.rs`, while the parser admits only manifest, manifest dread and cloak as chain-referent producers. A zone check would let any of the others overwrite the game-lifetime `LastCreated` ledger. `ChainReferentIntent { Silent, Publishes }` now rides `EntryMods` -> `PendingBatchZoneMoveRequest` -> `ProposedEvent::ZoneChange` -> delivery, so it survives a CR 616.1 park/resume with the rest of the request, and is consumed only once the entry has settled (`entered_battlefield`) — a `CantEnterBattlefieldFrom` rejection publishes nothing. `Silent` is the default, so a face-down delivery added later cannot opt in by accident. The mark sits on the producer, not on a list: manifest (CR 701.40a), manifest dread (CR 701.62a) and cloak (CR 701.58a) all reach the battlefield through `morph::manifest_card`'s one request, plus manifest dread's two-card continuation in `engine_resolution_choices`. Those are exactly the three the parser's `publishes_chain_created_referent` admits. The shared helper now installs characteristics and nothing else, which is what makes it safe for every other caller. Its unit row asserts that negative from both zones. ## The stale-referent half Writing the reviewer's requested test surfaced a second defect the first head also had: `LastCreated` is a game-lifetime slot, so manifest dread on an EMPTY library left the PREVIOUS instruction's referent standing and "that creature" reached back to it — the Machete equipped a creature the sentence never mentioned. A producer now clears the slot up front (`morph::begin_face_down_referent_production`, called by all three resolvers), and a successful delivery publishes. Split in two because the manifest family cannot assign at its tail the way the token producer does: a CR 616.1 entry pause can park the delivery past the end of the resolver. Net semantics are the token producer's — produced something: that id; produced nothing: empty. ## Coverage Two production rows, both starting with a REAL prior referent (an Ancestral Blade cast and resolved, leaving its Soldier token in the slot), so they can tell "published the new entrant" from "retained what was there": * accepted: the paused two-card choice is answered, and the Machete equips what its OWN manifest dread produced, never the earlier token. * nothing produced: the Machete stays unattached and the slot is empty. Counter-probe: | disabled | failing rows | |---|---| | the intent gate | plain manifest, the Machete row, the paused continuation | | the producer's up-front clear | `a_producer_that_produces_nothing_does_not_leave_a_prior_referent_standing`, on `ObjectId(4) from the previous instruction` | Also removed the duplicated explanatory comment in `imperative.rs` and repaired the "The The" typo in the surviving copy. Not covered: the four public `execute_zone_move*` wrappers pass `Silent`. They are raw movers with no originating instruction to speak for; a caller that needs to publish goes through `ZoneMoveRequest`. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

req.mods.chain_referentinto the proposed event on these two arms, mirroring the exempt-cause branch, to close this latent gap.Also applies to: 916-971

Approved at 9b51060: the typed chain-referent intent now reaches every zone-request construction path, including paused delivery, and the current-head parse artifact (7 intended cards) and runtime regressions are discriminating.

Approved at 2298b97cdfa833a50f125c15d7c4675276260297: the only post-review delta removes unrelated CR citations. The typed chain-referent intent remains correctly threaded through normal, paused, Library-placement, and Draw delivery paths; the current parse artifact accounts for the seven claimed cards, and the production continuation regressions remain discriminating.

Closes #7531.
Defect
A clause that puts a face-down permanent onto the battlefield produces exactly one new permanent and declares no target, so a following "it" / "that creature" has exactly one possible referent — the same situation as a token producer. The chain-referent machinery only recognised TOKEN producers, so the anaphor fell through to whatever the default was:
Attach { ParentTarget }ManifestDreadhas no targets → silent no-op, the Equipment never attachesPutCounter { SelfRef }Fix
Three parts, each on an authority that already exists:
publishes_chain_created_referent(lower.rs) widens the chain-referent predicate from "created a token" to "produced a permanent" —Manifest,ManifestDread,Cloaknext toPopulate/Token/CopyTokenOf.parse_attach_recipient(imperative.rs) routes a demonstrative recipient throughcounter_anaphor_created_token_binding, the authority the counter path already uses for the identical anaphor, so the two consumers cannot disagree about what "that creature" means. The bare"it"branch keeps its own, deliberately wider gate untouched.morph::publish_face_down_entry_referentrecords the face-down entrant in the same referent slot the token producer writes.manifest_cardis the one runtime producer for manifest / manifest dread / cloak; manifest dread's two-card arm moves the chosen card from its own continuation, so it publishes there too.Class
Every one of the 35,399 distinct cards in
client/public/card-data.jsonparsed with and without the change. Exactly 7 cards change, and every change is a fix:Attach { ParentTarget }Attach { LastCreated }Attach { ParentTarget }Attach { LastCreated }Attach { ParentTarget }Attach { LastCreated }Attach { ParentTarget }Attach { LastCreated }PutCounter { SelfRef }PutCounter { LastCreated }PutCounter { SelfRef }PutCounter { LastCreated }PutCounter { SelfRef }PutCounter { LastCreated }Counter-probe
With the demonstrative branch removed,
the_equipment_attaches_to_the_creature_manifest_dread_producedfails withattached_to: None;the_token_producer_sibling_still_attachesstays green, which is also what keeps the empty-library test's negative assertion from being vacuous.Not covered
Attach { SelfRef }. The bare object pronoun runs throughattach_neuter_recipient_resolves_via_subject, a wider gate this change does not touch.TriggeringSource— the counter path's trigger-subject gate re-anchors the demonstrative to the Room, which can never be the creature.ManifestDreadrow of Engine: the DraftFromSpellbook/ManifestDread tracked-set publish belongs in the WaitingFor continuation handler (Kayla's Kindling, Valgavoth's Onslaught, Dazzling Flameweaver) #7467. I measured that publishing that set is not sufficient on its own (the ability'srepeat_for Xwraps the follow-up clause, so with X = 2 the first creature ends up with 4 counters instead of 2) and reported the evidence on Engine: the DraftFromSpellbook/ManifestDread tracked-set publish belongs in the WaitingFor continuation handler (Kayla's Kindling, Valgavoth's Onslaught, Dazzling Flameweaver) #7467 rather than half-fixing it here.Attach { Any }— a different anaphor with its own producer.🤖 Generated with Claude Code
