Paper detail modal, feed figure sizing, and per-turn metrics

[SXKDZ]

Paper details became a modal, and the surfaces around it were measured and fixed: the byline disclosure, the venue chips, feed figures and tables, and the library toolbar. Ends with the v0.5.0 version bump.

Paper details and library

• paper details open as an accessible modal instead of a side drawer, with tabbed panels
• preprint identifiers consolidated onto one editable field
• author disclosures are measured at the width they actually render at: the separator is measured as the non-breaking space the byline emits (a trailing plain space is trimmed and bought phantom width per visible author) and every candidate carries the live toggle class, so type, weight, and inline margin come from the control that replaces it
• the venue monogram keeps all four letters at a new --type-nano step, with tracking left at normal (it trails the last glyph and pulls the acronym off centre) and the line box pinned to the font's ascent plus descent

Measured in a browser: 475 collapsed bylines across 25 viewport widths and a full column drag, zero overflow; all 10 monograms centre within 0.25px horizontally and 0.48px vertically with at least 4px of width to spare.

AI feed

• figures size to their content. Mermaid's width="100%" contributes nothing to a shrink-to-fit box, so every diagram was rendering at the 300px default of a replaced element; the viewBox is now the SVG's intrinsic size, so a narrow diagram hugs and a wide one scales to the measure
• the scale is floored at 0.7 so 16px diagram labels stay above the 11px text floor (11.2px on screen, from 4.1px); anything wider scrolls inside the canvas, capped at 70vh, and the scroll moved off the block so the open-in-new-window action stays pinned
• tables lay out automatically instead of at max-content, so a wide one wraps into taller rows rather than pushing every row onto a single scrolling line (a 1153px table becomes 714px wide and 238px tall, no horizontal scroll); a narrower table stays centred
• each turn ends with its local date and time, then speed, tokens, and elapsed time. Per-turn usage was not stored anywhere, so feed_messages gains three columns (existing rows default to 0 and show the time alone), the CLI's result-event usage is stamped on the message the turn ends with, and it is carried through the thread snapshot

Toolbar and menus

• the toolbar search field is elastic between 220px and 390px instead of fixed, and grows ahead of the status tabs; the tabs take the row's leftover width but never give any back. The fixed field had been hiding up to 257px of tabs behind a hidden scrollbar, leaving only "All" once the selection actions appeared
• floating menus animate in from the edge they open on, through one shared popover-enter keyframe

Verification

• npm test (build + 208 + 39 tests), tsc --noEmit, and lint all clean; the rebase ran the schema suite at every commit
• geometry claims above come from Playwright measurements against a throwaway clone of a real library, not from inspection

Known gaps

• per-turn metrics only populate for turns that run from now on; nothing back-fills old threads, and the write path is covered by tests and review rather than a live agent run in this environment
• "detail page not refreshed after editing" is unreproduced: every field updated immediately in the isolated environment, so it needs a concrete surface and field to chase

Follow-up pushed: the reader byline now runs the same adaptive component as the library table.

Both reported symptoms had one cause: reader-only and per-surface .author-toggle overrides that the hidden measurement could not see. The live control rendered at 700 weight / 13px where the measurement assumed 400 (107.98px vs 100.75px), so a tight fit crossed the clip edge; and those overrides matched only the direct-child control, so Show fewer authors (nested one level deeper) picked up a different style.

• one AdaptiveAuthors component for plain and linked names, one expandable-author-list class family, is-linked for clickable names
• the disclosure control is the last child of the name run in both states, so both labels share one rule
• the reader-only toggle override and the per-surface toggle type rules are gone; type comes from the one canonical rule the measurement mirrors

Measured after the change: live and measured control widths agree to 0.01px; zero overflow across 9 reader widths, a full notes-sidebar drag (9 samples), 42 table bylines over 6 viewport widths, the detail modal, and the overview cards.
