Finding inventory: PR #30002

Findings

Contested and acknowledged

CRF-1 (P3, AgentsPageLayout.tsx:678) - sm crossing slide state has no test

• Finding: The sm crossing slide state and its stale-slide handling had no test, so a regression in when the frame drops its route classes or clears the slide passes CI. Proposed a test that crosses (max-width: 639px) on /agents/:id and checks the slide clears on animationend and on navigating to the chat list.
• Author defense: Added a frame test that onViewportSlideEnd fires only for the frame's own animationend; the layout-level crossing needs the full AgentsPageLayout providers, which no unit test in the directory sets up, so it is left to browser verification.
• Panel re-raised (R2): Netero, the agent that raised it, re-raised: the render-time reset is now the only code that clears a stale "out", a regression renders invisible w-0 in place of the mobile chat list, and AgentsPageLayout.stories.tsx already renders the full layout with providers while AgentChatPage.stories.tsx:1712 crosses a breakpoint with setupMatchMedia; Pixel disables animations, so a stale "out" is deterministic in a screenshot.

CRF-2 (P3, RightPanel.tsx:316) - pinning and narrow slide-out state untested

• Finding: isAnimatingOpen and the narrow slide-out state had no test; proposed jsdom tests firing transitionEnd/animationEnd on the panel.
• Author defense: Both states only change class names with no callback, request, or state outcome; FE1/FE10 prohibit class-name assertions; widths were sampled in Chromium.
• Panel closure (R2, 1/1): Netero, the agent that raised it, accepted: a regression ships as an animation glitch with no functional loss, and neither a test nor a Pixel screenshot (animations disabled) can observe these states without restructuring into a hook.

CRF-3 (P4, RightPanel.tsx:444) - closed lg class drops border-l during close

• Finding: The divider disappears at the start of the 200ms close at lg; proposed adding border-l to the closed lg class.
• Author defense: border-l on the closed w-0 box leaves a permanent 1px column (measured in Chromium), shifting every closed-panel layout.
• Panel closure (R2, 1/1): Netero, the agent that raised it, accepted: a 200ms missing divider costs less than a permanent layout shift.

CRF-11 (P3, AgentsPageLayout.tsx:678) - breakpoint-crossing slides

• Finding: The 640px/1024px crossing slides take roughly 85 production lines and carried the stale-slide and test-gap findings; proposed dropping them or fixing those findings.
• Author defense: The PR's requester explicitly asked for the crossing slides; the stale replay, stuck slide-out, and test gap are addressed in their own threads.
• Panel closure (R2, 1/1): Luffy, the agent that raised it, accepted the requester's stated need and verified the stale-slide paths are fixed (render-time reset in AgentsPageLayout, isNarrowSlideOut reset on reopen and on returning to lg). The remaining layout-level test gap is tracked in CRF-1.

CRF-1 (P3, AgentsPageLayout.tsx:717) - round 3 dispute

• Finding: The sm crossing slide state and its render-time reset have no layout-level test; round 2 proposed a story that crosses (max-width: 639px) on /agents/:id and navigates to /agents.
• Author defense (R3): A story would render desktop CSS (Storybook viewport stays desktop) with mobile JS state from setupMatchMedia, a combination users never see, and would need a play navigation step the layout stories lack; the reset is one render-time condition and the frame's slide-end contract is unit tested. Left for a human reviewer to accept or ask for more.
• Panel re-raised (R3): Netero, the agent that raised it, re-raised with new evidence: the desktop-CSS objection applies to a story, not a unit test; the transition at AgentsPageLayout.tsx:704-724 depends only on isMobileViewport, prevIsMobileViewport, isSidebarHiddenOnMobile, isSidebarCollapsed, and the current slide, so it can move into a pure function tested with it.each in AgentsPageLayout.test.ts, the same pattern this round used for applyNarrowWidthCollapse. Rows: a stale "out" after navigating to the chat list becomes null; a stale "in" after a user collapse becomes null.

CRF-35 (P4, RightPanel.test.tsx:394) - single unexplained test failure

• Finding: restores a sidebar it collapsed after the panel remounts failed once on a cold run at f5f777a with no failure output; proposed running both files in a loop and reporting the count.
• Author defense: 25 of 25 loop runs passed at 2efe7ca; attributes the earlier failure to async ResizeObserver polyfill callbacks removed by the MockResizeObserver stub.
• Panel closure (R3, 1/1): Netero, the agent that raised it, accepted: about 85 passing runs since the single failure (Netero 24 at f5f777a and 10 of 10 at 2efe7ca with all three test files, the author's 25, the orchestrator's 25); worst case is a rare CI rerun. Netero corrected the author's cause: f5f777a already stubbed ResizeObserver in this describe, and that is the commit where the test failed, so the cause remains unknown.

CRF-51 (P4, RightPanel.tsx:396) - Expand sidebar slides partway open, then re-collapses

• Finding: When the sidebar and the panel do not both fit, "Expand sidebar" sets the collapse reason to null, and the auto-collapse observer collapses the sidebar again during the 200ms transition, so it slides partway open and back. Proposed: skip the re-collapse for a user-requested expand until the next panel open, or disable the button while the reason is narrowWidth and the restore check fails.
• Author defense (R4): The re-collapse predates the PR (a one-frame flash before), and changing it means choosing between two product behaviors (let the expand squeeze the panel, or disable the button), which is out of scope for an animation PR; flagged for a human reviewer.
• Panel closure (R4, 1/1): Nami, the agent that raised it, accepted: the end state matches base, and the PR improves it because the re-collapse is recorded as narrowWidth and restored once there is room or no panel is open (base left it collapsed); the only new cost is the partial slide. Nami listed the button's behavior in that width range as out of scope for a human decision (CRF-66).

CRF-51 (P4, RightPanel.tsx:396) - round 7 re-check after the restore removal

• Finding: Same as above. 0757b36 removed the narrowWidth reason and restore that the R4 closure cited; Luffy's R7 output asked Nami to re-judge.
• Author defense: Unchanged from R4 (predates the PR; the fix is a product choice, CRF-66).
• Panel closure (R7, 1/1): Nami (a new agent, R7 panel; the R3/R4 outputs were listed in context.md, and the orchestrator asked it to judge the closure explicitly) accepted: the auto-collapse effect body is unchanged from base, so the end state is exactly base (collapsed, no restore); the only PR difference for that click is a partial slide of up to 200ms instead of a one-frame flash; making the button work is the CRF-66 product decision.

Round log

Round 1

Full panel, round 1. Classified multi-domain (TSX and CSS keyframes), target 9 to 12. Netero first pass: 2 P3, 1 P4, 1 Nit, 1 Note, 1 out of scope; no P0, so the panel ran. Law not run (284 effective additions). Panel: Ging-TS, Ging-React, Nami, Killua, Luffy (triggered specialists), Pariston, Mafuuu (core), Bisky (tests changed), Gon, Leorio (once-per-PR floor), Hisoka, Komugi (pool), Chopper (random wildcard from the distilled set). 13 panel reviewers, one over the target because Gon and Leorio were placed in round 1 by the floor.

Cross-check:

• CRF-7: six reviewers converged; P2 set by Nami and Pariston (higher wins). Orchestrator verified key={agentId} at AgentChatPage.tsx:739 and the loading view's <RightPanel isOpen> at AgentChatPageView.tsx:1137.
• CRF-8: raised from Hisoka's P3 to P2. Consequence when hit is a continuous collapse/restore oscillation until a window resize. Orchestrator verified ResizableChatsSidebarFrame reads storage only at mount and on window resize (no storage listener), which adds a second trigger: another tab saving a different width. Inferred, not reproduced.
• CRF-10: Hisoka P3 vs Mafuuu P4 and Chopper P4; Hisoka reproduced with setItem throwing, so P3.
• CRF-12: Komugi's Note (mutation check fails) contradicts Bisky. Orchestrator ran SIDEBAR_RESTORE_HYSTERESIS = 0: the test alone failed 8 of 8 runs; the whole RightPanel.test.tsx file passed 7 of 8 runs. Bisky's finding stands; Komugi's Note dropped as contradicted.
• CRF-22 and CRF-23: Gon P3 vs Leorio P4/Nit with equal evidence; higher wins.
• CRF-24 drop gate. Keep argument: AGENTS.md requires substantive comments and the line repeats the names below it. Drop reason: it states that mobile hides the sidebar on these routes, which is why the block exists; the names alone do not say that. Drop wins.
• CRF-25 drop gate. Keep argument: the doc describes what the harness body visibly does. Drop reason: the PR only corrected a pre-existing doc to the new behavior and it states the restore purpose. Drop wins.
• CRF-21 kept at P3. Keep argument: CRF-15 shows the raw flag does go stale, so picking the wrong name renders a stale slide-out.
• CRF-29 kept as Nit. Keep argument: "auto" stays ambiguous wherever the flag lives after the CRF-7 fix.
• CRF-31 vs Gon's comment audit (kept the hysteresis comment): Leorio's evidence (24px vs sub-pixel) is more specific; kept at P4.
• Interactions: the CRF-7 fix (collapse reason in AgentsPageLayout) also resolves CRF-4, CRF-18, and affects CRF-29 and CRF-8. CRF-11 (drop crossing slides) would remove CRF-14, CRF-15, CRF-21, CRF-22, CRF-23 and parts of CRF-1, CRF-2, CRF-27.
• Positive Notes from Nami, Bisky, Leorio, and Komugi record cleared concerns; not posted.
• Gon cited sidebarCollapsedByDrag at line 111; it is at line 110.

2 P2, 10 P3, 11 P4, 5 Nit, 2 Note (body), 1 out of scope, 2 dropped. Reviewed against 5dde49d..1aee330.

Round 2

Restructure round: the fix commit f5f777a added three fields to the exported AgentsPageOutletContext type and a ref prop to ResizableChatsSidebarFrame, and rewrote the auto-collapse effect and the narrow slide-out state rather than patching them. Churn guard: PROCEED (25 addressed, 1 acknowledged, 2 contested, 0 silent); CRF-1 (partial fix, layout test declined) and CRF-3 (acknowledged but defended) were treated as contested so the raiser judged them. Netero reused its round-1 agent (dispute check-in for CRF-1, CRF-2, CRF-3); Law not run (463 effective additions). Panel: Ging-TS, Ging-React, Nami, Killua (specialists), Pariston, Mafuuu (core), Bisky, Gon, Leorio, Hisoka, Komugi (pool; Gon and Leorio mandatory because comments and doc comments changed), Kite (random wildcard), plus Luffy on its round-1 agent for the CRF-11 dispute check-in (not counted toward the target). 11 counted reviewers, target 9 to 12.

Dispute check-in: CRF-1 re-raised by Netero; CRF-2 and CRF-3 closed by Netero (1/1); CRF-11 closed by Luffy (1/1).

Cross-check:

• Fixes verified by the raising reviewers: CRF-7 (Luffy, Nami, Mafuuu; Netero ran the remount test against round-1 RightPanel.tsx and it failed), CRF-8 (Hisoka, Killua), CRF-9, CRF-10, CRF-17 (Mafuuu), CRF-12 (Netero: hysteresis mutation fails 4 of 4 whole-file runs), CRF-14 and CRF-15 (Komugi, Hisoka), CRF-21, CRF-26 to CRF-30 (Gon), CRF-23, CRF-31, CRF-32 (Leorio). CRF-13's test arrived but is weakened by the fix; tracked as CRF-40. CRF-22's rewritten comment is wrong; tracked as CRF-39 (new finding, fix introduced it).
• CRF-37: Nami, Pariston, Mafuuu, Kite at P3 (three reproduced in scratch tests); Luffy noted the same behavior and accepted it. Four specific reproductions against one acceptance; P3 stands.
• CRF-35 downgraded P3 to P4. Keep argument: a test failed once with no code change and nobody knows why, so CI can fail on it. Downgrade reason: one failure in about 49 runs (Netero about 24, orchestrator 25 of 25 passing on both files after the panel finished), on the first run in a fresh checkout, with no failure output; Komugi measured each waitFor at 40 to 220ms of its 1000ms timeout under 2-core contention, which contradicts Netero's timeout inference from the 1118ms test duration. Downgrade wins; still posted because the author can run the loop.
• CRF-40 merges Bisky P3 (user-collapse rule has no production-code test), Gon P3 (harness doc claims equivalence), Leorio Nit (same doc). Same cause: the harness reducer is a divergent copy of the layout's. Kept separate from CRF-34, which covers the width fallback.
• CRF-39: Gon P3, Leorio P4; higher wins. Leorio's suggested text used.
• CRF-41: Nami P4 vs Killua (no finding; one extra style read per frame during a drag). Kept at P4; the comment states the cost.
• CRF-42: Komugi named two cancel paths; the narrowing path resets isAnimatingOpen because suppression closes the panel and the visualOpen block runs. Only the drag path is posted.
• CRF-45 has no file location (PR description); anchored at AgentsPageLayout.tsx:752, the code the sentence describes.
• CRF-46: Kite also suggested splitting the PR; only the retitle is posted (Law threshold not met).
• CRF-49 drop gate. Keep argument: the first half of the doc repeats the field name, which AGENTS.md's substantive-comment rule targets. Drop reason: "even while collapsed" is the contract a caller needs, and the sentence reads as one unit. Drop wins.
• Gon's CRF-43 reopens CRF-23 with new evidence (flex-row dependency omitted by the round-1 suggested wording).

5 P3 new, 7 P4 new, 2 Nit new, 1 P3 re-raised (CRF-1), 3 contested closed, 1 dropped, 1 out of scope new. Reviewed against 1aee330..f5f777a (full diff against 5dde49d).

Round 3

Restructure round: 2efe7ca changed the signature of the exported AgentsPageOutletContext.getExpandedSidebarWidth (() => number to () => number | undefined) and added exports applyNarrowWidthCollapse, SidebarCollapsedBy, and loadStoredLeftSidebarWidth. No files were added; effective additions grew 463 to 578. The commit only fixes prior findings, so a fix-round panel was also defensible; its selection (raisers of touched findings plus specialists for changed files, Gon and Leorio mandatory for changed comments) would have been the same set minus Hisoka. Churn guard: PROCEED (13 addressed, 2 contested, 0 silent). Netero reused its round-1 agent (dispute check-in for CRF-1 and CRF-35); Law not run (578 effective additions). Panel: Ging-TS, Ging-React, Nami, Killua, Luffy (specialists), Pariston, Mafuuu (core), Bisky, Gon, Leorio, Hisoka, Komugi (pool; Bisky required, Gon and Leorio mandatory on a restructure round), Kite (random wildcard from the distilled set). 12 counted plus the wildcard, target 9 to 12.

Dispute check-in: CRF-1 re-raised by Netero (new evidence: the slide transition can be a pure function tested like applyNarrowWidthCollapse, which answers the story objection). CRF-35 closed by Netero (1/1), with the correction that the ResizeObserver stub already existed at the failing commit.

Cross-check:

• Fixes verified: CRF-34 (Netero; residual harness width constant is CRF-52), CRF-37 (Nami, Pariston, Mafuuu, Kite, Luffy; Netero's mutation of the close condition fails the new test), CRF-38 (Netero mutation, Leorio), CRF-39, CRF-43, CRF-47, CRF-48 (Gon), CRF-40 (Bisky, Gon, Leorio), CRF-41 (Nami, Killua), CRF-42 (Komugi traced every path), CRF-44, CRF-45 (Leorio), CRF-46 (Kite). Luffy replaced its round-2 acceptance of the post-close collapse with approval of the close effect.
• CRF-50: Netero P3 (routes without agentId), Hisoka P4 (the proposed route check misses a chat's not-found and error views, AgentChatPage.tsx:717, :736). Same cause, merged; higher wins. Orchestrator confirmed no other writer clears sidebarCollapsedBy on route change and that only AgentChatPageView renders RightPanel. Base also left the auto-collapse in place (no restore existed), so this is a gap in the PR's new restore, not a regression.
• CRF-51: Nami P4, inferred from code, not run. Orchestrator traced: the expand sets null, the effect reruns, the ResizeObserver collapses when the parent drops below chatMinWidth + MIN_WIDTH during the transition.
• CRF-52: Bisky P3 with mutation evidence (1658 of 1658 passed with the layout's property name changed). Netero looked at the same harness constant and declined because the failure is now "never restore"; Bisky's point is that this failure is silent. Specific mutation evidence beats the decline; P3. Orchestrator found AgentsPageLayout.stories.tsx:542 and :667 read the frame's property by the same name, so a frame-side rename is caught by stories; the layout-side read and the ref are not.
• CRF-53: Gon P3, Leorio P4, equal evidence; higher wins. Keep argument for P3 recorded: the doc is false for the collapsed case it names, and the prior CRF-8 bug was a wrong width source. Interacts with CRF-52: if the read moves to sidebarWidth.ts and undefined goes away, only the "current width" half remains.
• CRF-54 downgrade gate (Gon P3 to P4). Keep argument: two synonym names for different contracts, and the wrong pick brings back CRF-38. Downgrade reason: the one caller where the wrong pick matters (the frame's userWidth) is pinned by grows a sidebar squeezed at mount back to the stored width, which Netero showed fails on the swap; the remaining cost is a future caller's choice. Downgrade wins; Mafuuu and Leorio also rated P4.
• CRF-55: Nami and Komugi both judged dragging-without-restore acceptable; Note (body).
• CRF-56 drop gate. Keep argument: AGENTS.md requires substantive comments and the condition says the same. Drop reason: the comment states why a panel close ends the collapse (it existed only to fit the panel). Drop wins.
• CRF-57 drop gate. Keep argument: CRF-25's drop relied on the doc naming the restore purpose, which the rewrite removed. Drop reason: the doc now names that the harness uses the layout's updater rather than a copy, which is what CRF-40 required; test-file doc. Drop wins.
• CRF-58 drop gate. Keep argument: the first sentence labels the block. Drop reason: it is the wording this review suggested in round 2; posting it would reverse our own suggestion. Drop wins.
• CRF-59 drop gate. Keep argument: "Records or clears" repeats the name and parameter. Drop reason: CRF-44 asked for this doc and Leorio verified it; the first clause tells a caller that false clears. Drop wins.
• CRF-60 drop gate. Keep argument: the user-collapse rule is written on both the context field and the function. Drop reason: an outlet-context consumer does not see the function, so each API surface carries its contract. Drop wins.
• CRF-61 drop gate. Keep argument: this round named the analogous union SidebarCollapsedBy. Drop reason: a mismatch between the layout state and the viewportSlide prop fails type checking, so the copies cannot drift silently. Drop wins.
• Gon's out-of-scope RIGHT_PANEL_SIDE_BY_SIDE_BREAKPOINT_WIDTH duplication is the same item as CRF-36; no new row.
• Positive Notes from Luffy, Komugi, Bisky, Leorio, Kite, and Killua record cleared concerns; not posted.

3 P3 new, 2 P4 new, 1 Note (body), 1 P3 re-raised (CRF-1), 1 contested closed (CRF-35), 6 dropped. Reviewed against f5f777a..2efe7ca (full diff against 5dde49d).

Round 4

Restructure round: c0453ae added the exported createOpenPanelRegistry, nextSidebarViewportSlide, SidebarViewportSlide, LEFT_SIDEBAR_WIDTH_VAR, and readLeftSidebarWidth, added registerOpenRightPanel to the exported AgentsPageOutletContext, and renamed the exported loadPersistedLeftSidebarWidth to loadClampedLeftSidebarWidth. No files were added; effective additions grew 578 to 782. Churn guard: PROCEED (5 addressed, 1 contested, 0 silent). Netero ran as a new agent (no Netero finding contested); no findings. Law not run (782 effective additions). Panel: Ging-TS, Ging-React, Killua, Luffy (specialists), Pariston, Mafuuu (core), Bisky, Gon, Leorio, Hisoka, Komugi, Robin (pool; Bisky required, Gon and Leorio mandatory on a restructure round, Robin for the three new helpers), Razor (random wildcard from the distilled set), plus Nami on its round-3 agent for the CRF-51 dispute check-in (also the frontend specialist; not counted toward the target). 12 counted plus the wildcard, target 9 to 12.

Dispute check-in: CRF-51 closed by Nami (1/1); the underlying button behavior moved to out of scope (CRF-66).

Cross-check:

• Fixes verified: CRF-1 (Netero: nextSidebarViewportSlide equivalent to the replaced branches; Bisky: each branch pinned by a row), CRF-50 (Netero mutation of the registration fails the close test; removing the frame wait fails the registry tests and the remount test; Nami, Hisoka, Komugi traced chat switch, loading-to-loaded swap, StrictMode, and the not-found and error views), CRF-52 (Netero, Bisky; residual layout wiring gap is CRF-65), CRF-53, CRF-54 (Leorio, Gon, Netero).
• CRF-62: Gon P3, Leorio P3, Mafuuu P4, Razor P4, same evidence; higher wins. Consistent with CRF-39 and CRF-53 (wrong comments at P3). Gon cited line 366 (blank); the comment is at 367, which the other three cited.
• CRF-63 downgrade gate (Gon P3 to P4). Keep argument: new code repeats the CRF-53 defect (a P3) and leaves undefined undocumented, and Gon adds that read vs load is the only name difference among three width functions. Downgrade reason: unlike CRF-53's "current width", this doc names the expanded width, which is the value callers need; the remaining inaccuracy is "renders" for "sets", and the number | undefined return with a four-line body shows the null case. Downgrade wins; Mafuuu and Leorio rated P4 with the same evidence. Gon's rename is included as an option.
• CRF-64: Gon P4, Leorio P4. The comment was CRF-24 (dropped R1); new evidence is that its referent moved.
• CRF-65: Bisky P4 with mutation evidence (1667 of 1667 passed with the context field removed). Same class as CRF-52 (P3 last round); Bisky rated this P4 and no reviewer argued higher. Keep argument for P3: the registry is now the only code that clears a narrowWidth collapse after close or navigation, and its layout wiring is one untested optional field. Stays P4 because the regression needs a deletion of that line, not a string drift.
• CRF-66: Nami's out-of-scope item after accepting the CRF-51 defense.
• CRF-67: Robin's two out-of-scope items (stories and skeleton literals) merged with the out-of-scope part of Gon's CRF-68; both predate the PR.
• CRF-68 drop gate. Keep argument: the new constant looks like the single definition while three Tailwind classes in the same PR file spell the name, and a constant-only rename breaks sidebar width with no type error. Drop reason: AgentsPageLayout.stories.tsx:557 to :707 assert sidebarWidth() values read by the literal name, so a constant-only rename fails CI; Tailwind cannot use the constant, so the only fix is a doc sentence. Drop wins.
• CRF-69 drop gate. Keep argument: the name says registry and both callers name the result as a function. Drop reason: the name describes the counter the closure holds, which the returned function is the only handle to; it is not false the way CRF-47's toggle names were. Drop wins.
• CRF-70 drop gate. Keep argument: the clause documents the consumer in the producer's contract. Drop reason: it is the wording this review suggested for CRF-53 in round 3. Drop wins.
• CRF-71 drop gate. Keep argument: the context field doc omits the frame delay that RightPanel.test.tsx:436-437 has to wait for. Drop reason: createOpenPanelRegistry, 20 lines below in the same file, documents the delay and why; "Registers an open RightPanel" names the caller, which () => () => void does not. Drop wins.
• CRF-72 drop gate. Keep argument: the first sentence describes the counter and the frame check in the body. Drop reason: it is the contract of an exported function, stated so a caller does not need to read the closure. Drop wins.
• CRF-73 drop gate. Keep argument: "after a render" misstates when the function runs, and two sentences restate the branches. Drop reason: the function returns the slide state that results from a render's inputs, and the sentences give the rules in product terms (sm crossing, routes that hide the sidebar) that five boolean parameters do not. Drop wins.
• CRF-74 drop gate. Keep argument: the doc repeats the name and the one-line body. Drop reason: CRF-54 asked for the siblings to be distinguishable, and the doc names the source (stored) and the clamp reference (current viewport). Drop wins.
• Komugi noted the frame wait relies on the old and new panels unregistering and registering in the same commit; a future Suspense or query-gated isOpen would break it. Hypothetical; the registry doc states the chat-switch assumption. Not posted.
• Positive Notes from Nami, Luffy, Pariston, Hisoka, Komugi, Killua, and Bisky record cleared concerns; not posted.

Round 5

Restructure round: 0f9e6bb added the exported hook useSidebarCollapseState, which now owns the layout's collapse state, and renamed the exported readLeftSidebarWidth to readExpandedLeftSidebarWidth. Every change maps to a round-4 finding, so a fix-round panel was defensible; the new exported hook moved state ownership, which is why the full panel ran. Effective additions grew 782 to 850. Churn guard: PROCEED (4 addressed, 0 contested, 0 silent). Netero ran as a new agent; no findings. Law not run. Panel: Ging-TS, Ging-React, Nami, Killua, Luffy (specialists), Pariston, Mafuuu (core), Bisky, Gon, Leorio, Hisoka, Komugi (pool; Bisky required, Gon and Leorio mandatory on a restructure round), Knov (random wildcard from the distilled set). 12 counted plus the wildcard, target 9 to 12. Robin not re-added (no in-scope findings in round 4; target reached).

Cross-check:

• Fixes verified: CRF-62, CRF-63, CRF-64 (Gon, Mafuuu, Netero, Leorio), CRF-65 (the harness runs the production hook; Netero and Mafuuu showed that deleting registerOpenRightPanel, from the layout's outlet context fails biome lint --error-on-warnings with an unused-variable warning at line 473; the orchestrator reproduced it and restored the file).
• CRF-75 merges four P4s. Pariston, Bisky, and Hisoka reported CRF-65 as not closed because deleting line 848 passes vitest and tsc; their "CI stays green" claim is contradicted by the lint result above, and the same holds for lines 844 to 847 (each destructured name or the readExpandedLeftSidebarWidth import becomes unused). Knov's framing survives the lint evidence: base routed auto-collapse through the required onToggleSidebarCollapsed, while the four new fields are optional, so a producer that omits them (a two-line edit in the layout, or a new producer) gets no type error and loses auto-collapse and restore silently. Keep argument for dropping considered: lint covers single-line slips and the remaining edit is deliberate. Kept at P4 because the exported type's contract weakened relative to base and the fix (required fields plus no-ops in the embed and two stories) is small. Pariston and Knov proposed required fields; Bisky and Hisoka proposed returning a typed outlet slice from the hook and spreading it. The comment gives required fields as the fix.
• CRF-76: Luffy and Knov both inferred from code (not run) that the embed no longer auto-collapses; Note (body).
• CRF-78: Bisky saw one unexplained failure in a full AgentsPage run; Hisoka identified useChatDraftAttachments.test.ts failing once under load and passing 17 of 17 alone. The orchestrator ran the full AgentsPage unit project 3 times at 0f9e6bb: 3 of 3 passed (1669 passed, 2 skipped). The PR does not touch that file.
• CRF-79 drop gate. Keep argument: no mutation distinguishes the hook test from the RightPanel close test, so one is redundant. Drop reason: the hook test pins the exported hook without RightPanel, width stubs, or the harness, so it survives changes to either; the RightPanel test covers the integration. Drop wins.
• CRF-80 drop gate. Keep argument: the doc names two of seven returned fields and one consumer. Drop reason: "owns why the sidebar is collapsed" covers the user actions, which only set that reason; the doc is accurate. Drop wins.
• CRF-81 and CRF-82 drop gates. Keep argument: each first sentence restates the code or name. Drop reason: both follow wording and a rename this review suggested in round 4. Drop wins.
• CRF-83 drop gate. Keep argument: CRF-57's drop reason (the doc named a contract the body did not show) no longer applies now that the body imports the hook. Drop reason: test-file doc, accurate, no caller reads it. Drop wins.
• CRF-84 drop gate. Keep argument: one returned object mixes verb names and an outlet handler name. Drop reason: the handler-named fields pass straight into outlet fields of the same name, and CRF-75's alternative fix would make every name the outlet name. Drop wins.
• CRF-85 drop gate. Keep argument: an identical helper is defined twice in one file by this commit. Drop reason: a two-line helper scoped to its describe, no rule broken, no reader affected. Drop wins.
• Nami, Killua, and Komugi confirmed the hook's callbacks close over only the state setter and lint:compiler reports no failures, so the auto-collapse effect's dependencies stay stable; not posted.
• Positive Notes from Luffy, Pariston, Mafuuu, Bisky, and Komugi record cleared concerns; not posted.

Round 6

Fix round: dcd5870 (+17 -4, 4 files) applies the CRF-75 fix as the round-5 comment described it (four AgentsPageOutletContext fields made required, no-ops in the embed and two stories). That is an exported-type change, but it is the requested fix applied as written, with no new exports, rewritten functions, or files, so "a round that only fixes prior findings is not a restructure" governs. Churn guard: PROCEED (1 addressed). Netero ran as a new agent; no findings. Law not run. Panel: Knov, Pariston, Bisky, Hisoka (raised CRF-75, whose code changed), Ging-TS, Ging-React, Nami (specialists for the changed .tsx files), Gon (declarations carrying doc comments changed, and a comment was added), Leorio (new commit message and comment), Zoro (random wildcard from the distilled set). 9 panel reviewers plus the wildcard.

Cross-check:

• CRF-75 verified by Netero, Bisky, and Hisoka: deleting registerOpenRightPanel, from the layout's outlet context now fails tsc with TS2741. Knov, Pariston, Nami, and Gon confirmed all four producers set the fields; the ?? {} and ?. in RightPanel remain for renders without an outlet, as in base.
• CRF-76 (Note, R5) is settled: the PR description now mentions the embed change.
• CRF-86: Zoro measured 441ms vs 6.71s import for otherwise identical one-test files. Orchestrator run: RightPanel.test.tsx reports import 7.25s; ResizableChatsSidebarFrame.test.tsx reports import 338ms. The value import from AgentsPageLayout started in round 3 (applyNarrowWidthCollapse, the CRF-40 fix) and the round-4 CRF-65 comment suggested exporting the hook from AgentsPageLayout.tsx, so this is a regression from our own suggestion; the comment says so.
• CRF-87 merges Leorio P4 (description sentence false for drag-to-edge) and Gon P2 (the embed comment overstates the same thing and could be shorter). Orchestrator verified useResizableDrag calls onToggleSidebarCollapsed at RightPanel.tsx:148-156 and :206-211, and the embed passes its real toggle at AgentEmbedPage.tsx:232. Downgrade gate for Gon's P2: keep argument, Gon rated it P2 and the comment is new text in the fix commit. Downgrade reason: no runtime effect; the comment is literally true about the four no-op fields, and description inaccuracies were P4 before (CRF-45). P4 wins.
• CRF-88 drop gate. Keep argument: a one-caller wrapper duplicates the composition the frame writes inline. Drop reason: the round-3 CRF-54 comment offered rename or inline and the author chose rename; the wrapper existed at base with the same body. Drop wins.
• Netero noted the embed's no-op onSidebarCollapsedByNarrowWidthChange now lets the auto-collapse effect run in the embed (an idle observer and one no-op call); behavior unchanged. Not posted.
• Positive Notes from Knov, Bisky, Hisoka, Nami, Ging-React, and Pariston record cleared concerns; not posted.

Round 7

Restructure round: 0757b36 (+54 -502, 10 files) removed the auto-collapsed sidebar restore instead of patching CRF-86 and CRF-87: it deleted the exports useSidebarCollapseState, createOpenPanelRegistry, applyNarrowWidthCollapse, SidebarCollapsedBy, readExpandedLeftSidebarWidth, and LEFT_SIDEBAR_WIDTH_VAR, removed four fields from the exported AgentsPageOutletContext, reverted RightPanel.test.tsx and AgentEmbedPage.tsx to base, and changed the PR title and goal back to animation only. Effective additions fell 850 to 361. Churn guard: PROCEED (2 addressed, 0 contested, 0 silent). Inventory validation: CRF-67 dropped (the constant it compared against no longer exists); CRF-55 and CRF-76 (Notes about removed code) left as recorded; the remaining dropped, Note, and out-of-scope rows still describe the current code or describe code that no longer exists. Netero ran as a new agent; no findings. Law not run (361 effective additions). Panel: Ging-TS, Ging-React, Nami, Killua, Luffy (specialists), Pariston, Mafuuu (core), Bisky, Gon, Leorio, Hisoka, Komugi (pool; Bisky required, Gon and Leorio mandatory on a restructure round), Kite (random wildcard from the distilled set). 12 counted plus the wildcard, target 9 to 12 (multi-domain: TSX and CSS keyframes, as in round 1).

CRF-51 re-check: Luffy noted the R4 closure cited the removed restore. The orchestrator asked the R7 Nami agent to judge it explicitly; Nami accepted (1/1) against the current code.

Cross-check:

• CRF-86 and CRF-87 verified by Netero, Pariston, Leorio, and Kite: no references to the removed names remain (rg over site/src), RightPanel.test.tsx and AgentEmbedPage.tsx match base, and the description no longer mentions the embed.
• CRF-89: Ging-React P2, with the compiled output and a jsdom reproduction. Orchestrator compiled the frame with babel-plugin-react-compiler (default options): t4 = getLeftSidebarMaxWidth() sits inside a react.memo_cache_sentinel guard. Orchestrator reproduction (temporary test, deleted): stored 600, mount at 800px, widen to 1440px gives [aria-valuenow, aria-valuemax, max-width var, width var] = ['600', '440', '440px', '600px']. Clipping is inferred from the classes (sm:max-w-(--agents-left-sidebar-max-width) and sm:overflow-hidden on the frame, sm:w-(--agents-left-sidebar-width) on the new wrapper), not run in a browser. Pariston's premise that the sidebar box never shrinks below --agents-left-sidebar-width holds only while the cached max is current. Downward test: only users whose stored width exceeds the mount-time max, or who drag after widening, see it, and a reload or a narrower drag clears it. Upward: the clipped strip holds the right side of every chat row, and base showed no clipping (children filled the capped frame). P2 (wrong but survivable) stands. The base cap for drags and End presses is CRF-94, out of scope; the CRF-89 fix also covers it.
• CRF-90: Mafuuu P4 and Komugi P4, both with a jsdom reproduction; Komugi's Playwright run fired no transition events for position:absolute; inset:0 to width:min(...). Orchestrator confirmed AgentChatPageView.tsx:376-379 gates expansion off instead of resetting it, so a reopen restores it. Same root cause as CRF-16 and CRF-42 (the flag is cleared only by a width transitionend); the fix sets it only for side-by-side opens.
• CRF-91 downgrade gate (Gon P4 to Nit). Keep argument: two expected widths do not name which of three clamps produced them, a change to AGENTS_MAIN_PANEL_MIN_WIDTH breaks them with no pointer, and the same file derives expectations from LEFT_SIDEBAR_DEFAULT_WIDTH. Downgrade reason: the tests fail loudly with innerWidth stubbed on the line above; no coverage or behavior risk; divergence from the file's own pattern is the Nit definition. Downgrade wins.
• CRF-92 drop gate. Keep argument: after the first drag storedWidth no longer matches storage, and a later edit could use it in the resize handler and regrow to the mount-time width. Drop reason: const [storedWidth] = useState(...) with no setter reads as a mount snapshot, and both uses are the next three lines. Drop wins.
• CRF-93 drop gate. Keep argument: CRF-46 was posted and fixed for this, the author reverted the title, and git log --oneline and the generated changelog show only the title. Drop reason: Kite, who raised CRF-46, judged no re-raise because the description lists the regrow as its own bullet; squash commits on main carry the PR body (verified on 2c1e888 and 93a00bd); Leorio's stated consequence (bisect skipping a commit by title) does not follow, since bisect tests every candidate. Drop wins. CRF-46's status records the revert.
• Contradiction: Leorio (re-raise CRF-46) vs Kite (no re-raise); resolved in CRF-93.
• Positive Notes from Luffy (removal matches the requester's ask), Bisky (mutations fail the remaining tests), Leorio (comments accurate), Killua (no unbounded work; CRF-33 still describes the code), and Kite record cleared concerns; not posted.
