Lineage lines used to draw one glowing dashed bezier per parent/child pair,
hanging below the tab strip, for every family at once. With a parent on row 3
of a wrapped strip and ten children below it, the curves crossed every lower
row's tab names and ran through the terminal text.
- One rounded orthogonal tree per spawning tab: every route starts at the
parent, so siblings share a trunk. 1.5px, solid, 1px dark outline; only a
working child's branch is dashed.
- Routes run only through the gaps between tab rows, joined by a spine left of
every row (computeLineageTree/computeLineageRows in constants.js), so they
never cross a tab or reach the terminal. The vertical rail gets the same tree
on its existing left track.
- Only the selected tab's family is drawn (what it spawned, plus its parent and
siblings). Selection redraws, and the strip's size transitionend redraws once
more, since the active tab widens for ~150ms after the selection redraw.
- The routing room is reserved by .session-tabs.lineage-tree, keyed on whether
any lineage exists, never on the selection, so a tab switch never resizes the
header or the PTY.
- Colours stay per spawning tab, now claimed in strip order for every family so
selection order never decides who gets the skin blue.

Lineage arcs were coloured per child, so one tab's own workers each got a
different colour, which is the distinction the colours exist to make. The colour
is now keyed on the parent: every arc leaving one tab is the same colour however
many workers it spawns, so the strip reads as "these five came from w1, those
two came from w2". A child that spawns in turn is a parent in its own right and
gets its own colour for the arcs below it, so a chain changes colour at each
generation while each generation's fan-out stays uniform.
The new tests drive the real _appendLineageConnectionLines() and assert the
painted custom property, because testing the colour function alone passes just
as happily with the child id passed back in.

- SKILL.md: forbid the standalone preamble check and pre-spawn recon turns
(measured: two wasted model turns cost ~12s of a 28s two-worker run; the
hardened flow measured 20.2s cold / 12.8s warm end to end)
- Lineage lines: dip now hangs from the strip's bottom edge (cap 104 -> 64,
no stacked row offsets), fixing the deep bow in wrapped strips and keeping
row-1 arcs off row-2 tab labels; per-child color palette (skin blue first,
then matrix green, pink, violet, red, turquoise, orange) via an inline
--lineage-color custom property
- Session Options -> Session: per-TAB pop-out (open-in-window) button override
on top of the general showTabDetachButton setting; per-device localStorage
map rendered as the tab-show-detach class
- Tab alerts: seed the pending-hook state machine from GET /api/approvals
regardless of the approvals-inbox setting (reloads used to lose the red tab
entirely with the inbox off), clear unconditionally on approval_resolved,
and repaint the alert as a steady red/yellow ring + glow + status dot on a
::before overlay so it stays visible on the selected (active) tab until the
permission is actually resolved
- docs: worker warm-pool design sketch (verified numbers baked in)

The lines that join a tab to the workers its codeman skill spawned were
drawn with numbers tuned against two tabs sitting side by side, and they
degraded in exactly the two situations the feature is actually used in.
1. A spawned worker is appended to the END of the strip, so the real span
between a lead and its worker is 800-1500px. With the dip clamped at
44px that is a 33px sag: the arc reads as a straight line drawn across
the terminal instead of a bracket hanging under the strip. The dip now
grows at 0.085/px and clamps at 104.
2. When the desktop strip wraps (tabs-two-rows / tabs-auto-wrap), a parent
on row 1 and its child on row 2 are ~14px apart, and the cross-row
branch drew parent-bottom to child-TOP: a flat line hidden inside the
row gap, with siblings overprinting each other. Both ends now anchor on
the tab BOTTOM with the control points below the LOWER row, so a wrapped
pair gets the same bracket a flat strip gets. That deletes the branch:
one shape covers both.
Visibility, at 1:1 rather than in a zoomed mockup: 2 -> 2.5px stroke,
4 4 -> 5 5 dashes (lineage-flow moves with them, -16 -> -20), opacity
.55 -> .72, and a second wider glow so the contrast comes from the halo
rather than from more weight, keeping the line under the subagent lines'
3px. A working child is bright (.95) outside the reduced-motion block, so
turning motion off no longer also dims every worker's arc. Sibling nesting
6 -> 8px and the direction dot 3 -> 3.5px to match the heavier stroke.
Verified at 1:1 in a harness driving the real styles.css and the real
computeLineagePath over three layouts (adjacent workers, workers at the
far end of a full strip, wrapped two-row strip) on a dark and a light
skin. test/session-lineage-lines.test.ts pins both regressions.
