…ncy counts, hyperbolic re-rooting - report-ui/domTree.ts: SCC condensation + Cooper-Harvey-Kennedy dominator tree + exclusive counts, and bitset reach counts (unit-tested incl. cycles, diamonds, 8000-chains) - Flame view rebuilt over the dominator tree: every package drawn once, width = packages deleting the bar frees, grey shared band for packages no single dependency owns - New Treemap mode: squarified layout of the same tree, area = removal cost, drill-in on double-click - List view: SUB-DEPENDENCIES in the expanded Overview (exact unique count beneath each package) + sort-by-sub-deps - Balloon bodies sized by unique reach; dossier shows 'N packages in subtree' + 'deleting frees N packages'; all path counts removed from every label (they were internal layout weights, not user information) - Hyperbolic re-roots on focus (#101): the focused package becomes the layout origin, its dependencies fan wide, the route back to the project compresses toward the rim but stays visible Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- P1: dominators computed per-node with Cooper-Harvey-Kennedy directly on the cyclic graph — the SCC-collapse projection misattributed multi-entry cycles (mutually-dependent direct deps showed one owning the other); condensation now serves only cycle annotations and the reach DP. New tests: mutual direct deps, multi-entry cycles, single-entry cycles, multi-component shared band - Flame widths normalise by parent weight, so width == removal cost at every level (the parent's own unit shows as the trailing sliver); the top level accumulates sub-pixel direct deps into the spray marker - Treemap: single click selects without relayout; double-click drills into the box the user saw (ancestor one level below the zoom), shared block drills on double-click; shared lightness clamped on deep chains - Hyperbolic transitions snap exactly onto the computed layout on finish and on interruption (mid-blend frames are not valid hyperbolic configurations); clamp removed from the lerp (convexity) - Consistent wording: status line says 'in subtree' (inclusive) matching the dossier; list Sub-dependencies stays exclusive; cycle membership annotated in the dossier; sub-deps sort follows the ascending-arrow convention; stale 'four modes' comments and README bullets corrected Tests: 247 across 24 files Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…11y round Release blockers: - Impact metrics (subtree size, what removal frees, cycles) now come from the UNFILTERED workspace graph via vizModel.impact(); display filters only change what renders, never what removing a package would free. - Direct dependencies distinguish manifest removal from node deletion: a direct dep that other packages still pull in reports "removing it frees nothing — still needed by X" instead of its dominator footprint. - Treemap nests reserve the parent's own weight unit (phantom self item), so nested areas stay proportional to package counts; squarify extracted and covered by geometry tests. Treemap navigation: double-click the zoomed box to climb out one level, leaf double-clicks no longer reset, and the Reset button reappears while zoomed (the tiled stage has no empty space to double-click). Also: hyperbolic phase-boundary jump fix for rim-deep carries, clicks mid-transition select what was actually seen, per-theme key swatches for the hyperbolic legend, key dropdown a11y (chevron hidden, panel role, Escape focus guard, focus-visible ring, viewport clamp), desktop Sub-deps column (sortable), five-mode switch scrolls on small phones, alt-view canvases carry aria-labels, treemap tooltip hides on drill and clamps to the usable stage, flame measure docstring corrected.

…nuity - The column-headers/dep-indicators grids hardcoded 6 columns while the code sets --column-count, so the new Sub-deps column wrapped every card onto a phantom second row; the grids now read the variable. - Balloon: draw() called usableW()/centreY() — and through them getComputedStyle — once per placement (250k on a monorepo), freezing every idle frame for ~300ms; the offsets are now cached per frame (idle draw ~40ms). Edges and sub-2px dots batch into one stroke/fill per style group. pickAt now measures in screen space against the radius a node actually renders at (including depth floors), so clicking what you see works zoomed out; the click threshold tolerates the drift of a slow frame; fly-to frames use the interaction LOD. - Hyperbolic re-roots keep their bearings: the new layout is rotated so the route back to the project keeps the direction it had on screen — a subtree focused from the bottom-left stays bottom-left instead of the whole picture flipping to a canonical orientation. Same on reset. - Flame gets the treemap's cursor tooltip (deep bars are too narrow to carry labels). - The scan-evidence toast sits bottom-left in graph mode instead of parking mid-canvas to dodge the docked panel. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- Focusing a package in the hyperbolic view now RE-ROOTS the spanning tree at that package: a BFS from the focus claims everything it can reach, so its real dependency tree (shared deps included) fans out around it instead of staying bundled wherever the hub-rooted tree's first claimer put it. The context (everything unreachable from the focus) keeps its structure and hangs off a capped wedge (max 40% of the circle), so a small package's subtree gets generous room instead of a sliver. Edge drawing follows the active layout tree. - Gentle TNG-style flow pulses drift along the focus paths — outward on the dependency links, homeward on the amber route (~30fps, only while selected, skipped under prefers-reduced-motion). - The scan-evidence toast sits bottom-left in BOTH views, so it no longer jumps corners entering the graph. - Balloon: selecting a node now fits its whole system (enclosing balloon radius) into view — zooming out if needed — instead of inflating one circle to fill the screen with the children off-screen. Node radii decay slower than the layout unit (unit^0.82) so deep nodes stay visible, and connecting lines thin out level by level. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- Balloon connectors now show whenever they are LONG on screen, not only when the child renders large — zoomed into a system, the tree structure stays visible; edge alpha scales gently with length. Sub-hub bodies lift from 20% to 27% lightness so they no longer vanish into the dark background, and the hovered/selected body always renders at least 5px. - Hyperbolic flow pulses run at a third of the speed, and the amber route's direction is reversed: flow arrives from the project into the selection and leaves outward through its dependencies. - Long dossier facts (cycle membership, "still needed by …") render as full-width notes with a top-aligned icon instead of multi-line pills. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- The balloon gets the same cursor name tag as the treemap and flame views (name · packages in subtree), hidden while dragging and on leave/fit/drag-start — the tiny deep leaves finally have names. - The scan-evidence toast anchors bottom-right in both the list and the graph views; in graph mode it overlays the docked panel's corner until dismissed rather than jumping corners between views. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Two ends of one problem. The render-radius boost grew unbounded with depth (unit^0.82), so by five-six levels down sibling circles inflated into each other; it is now capped at 1.45x the true layout radius. And large fans placed every child on ONE arc whose radius came from the arc-capacity formula, so a 40-child hub orbited its children so far out that the parent was a speck in empty space; fans with more than six children now round-robin across two or three concentric shells (each with its own angular cursor), pulling children in close. The enclosing- radius memo uses the same shell formula, so sibling systems still never collide. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…on polish - The toolbar filters move into a dropdown like the Key, with two sections: Show (runtime/dev/sub-deps chips + depth cap, unchanged semantics) and Highlight — vulnerable, maintenance concern, replacement suggested, licence issue, upgrade blocker. Highlights dim every non-matching package across all five layouts (memoised per model so monorepo-scale canvases stay fast), persist with the other filter state, and the toggle carries an active-count badge. - Hyperbolic focus lines extend one hop further at half strength — where the selection's dependencies go next — with a fainter version of the same flow pulses. - Balloon: shell assignment is now greedy by ring capacity with heavy children claiming the inner rings, so long outer-shell leashes belong to lightweight systems; sub-2px leaves render firmer (alpha up, circle threshold down) so crescents read as points, not dust. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…label plate - The graph view's Key/Filters toggles now use the list view's toggle recipe (border, radius, accent hover, accent-subtle open state), the count badge matches the list badge, and every view-selector button — the five mode buttons, the list view's Graph View pill, Back to List View — shares the same accent hover border. Filter chips too. - The Filters dropdown gains a Reset filters button: defaults restored, highlights cleared, one click. - Balloon: the fan-spread cap scales with child count (up to the full fan for 9+ children), so a many-child hub with empty arc around it opens up instead of holding a needle spike. - Hyperbolic: the selected package's label sits on a tooltip-style backing plate, readable over its own bright focus lines.

Correctness/honesty: - Dossier kind chip now follows the unfiltered impact graph, so hiding dev deps can't relabel a direct dev dependency as a sub-dependency while its removal fact still speaks manifest language. - Flame/treemap count labels append "shown" under non-default filters — the filtered dominator weights are what renders, not true removal cost, and the two numbers no longer masquerade as the same thing. Hyperbolic: - Double-clicking a node no longer deselects it and resets home (the second click landed mid-transition and picked nothing); a focus click suppresses the deselect/reset paths for 500ms. - Reset view clears the selection like the double-click reset does, so the flow animation stops; wheel zoom cancels an in-flight transition instead of fighting its offset writes; the faded second-hop edge list is capped at 600. Balloon: - pickAt falls back to a linear scan when the grid walk would touch more cells than there are placements (zoomed far out it was O(reach^2) per pointermove). - Fan geometry (shells + orbit) is now a shared helper that only accepts extra shells while the radial gap can hold two child enclosures, so adjacent rings cannot overlap; shell assignment is first-fit inner-to-outer against ring budgets (the old capacity score sent the HEAVIEST child to the outermost ring); each ring's cursor centres on its real span, clamped so skew-loaded rings cannot wrap. - Wheel zoom hides the stale tooltip; reset view clears the selection. UI state/CSS: - Fresh view mounts reset the treemap zoom flag (stale Reset button after filter/workspace changes); the filters badge no longer counts an inert depth cap; only one toolbar dropdown opens at a time (keyboard activation fires no pointerdown); classic-graph dimming is memoised per slug; the toolbar stacks above the side panel so open dropdowns are not clipped; count badges use dark text (AA on accent); highlight swatches get light-theme variants; reset buttons join the shared focus-visible ring; narrow screens anchor the filters panel on-screen; stale toast comment removed. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
root label priority, compact mobile notice - The list shows BOTH numbers side by side: Sub-deps (unique reachable packages beneath it) and a new sortable Frees column (what removing it actually uninstalls — dominator footprint, 0 for a direct dependency other packages still pull in). Same maths as the graph dossier, over the whole project's roots. The expanded Overview adds "Removal frees", spelling out "Nothing (still required by other packages)" for the vite-style case, and the mobile sort select gains Frees. - The graph Filters panel anchors to the viewport below the toolbar on narrow screens (fixed 12px insets, min-width dropped) instead of rendering from x=-77px with clipped controls at 320px. - Hyperbolic labels give direct dependencies their own priority tier ahead of size-qualified transitive labels (collision pruning intact), so the first ring is named before anything else. - The scan-status notice compacts on small phones so it stops blanketing the graph stage. Desktop stays bottom-right in both views as chosen. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

- fanGeometry also requires the largest child to fit a single ring's angular capacity before accepting extra shells — one dominant child among many small siblings could overflow its ring and be compressed into overlap by the span clamp. - Balloon drag start clears the hover highlight and trail (the drag branch skips hover recomputation, so a stale highlight survived pans). - Flame resize resets the positional hover index and hides the tooltip, matching the treemap. - The hyperbolic label plate falls back to square corners when ctx.roundRect is unavailable (needs Safari 16.4+/Firefox 112+) instead of throwing mid-render. Not applied: the README wording suggestion for the balloon — bodies are deliberately sized by unique reach (uniqueCount), not removal cost, so the existing sentence is accurate.

What this is
The answer to mindplay's question — "how many packages would actually get removed?" — made into the report's core mechanic, everywhere. Built on a Cooper–Harvey–Kennedy dominator tree computed per-node on the real (cyclic) dependency graph: a package's dominator subtree is exactly what leaves node_modules when it goes.

Review history
Three multi-agent adversarial rounds (26/25/26 agents; the P1 dominator-on-cyclic-graph fix was brute-forced against ~70k random graphs) plus two external review rounds, all findings fixed with the reasoning captured in the commit messages. Gate: typecheck, 252 unit tests / 25 files (incl. dominator maths, impact semantics, treemap geometry, template sync), schemas, core fixtures, production build.
Known deferred: full keyboard navigation for the canvas views (the list remains the accessible path; canvases carry labels saying so), removal simulator + further impact features tracked for later in v1.2.
