Campaign CT slice B1.
CORRECTION TO THE PLAN: this slice was written as "the transcript grows for the
life of the session — a slow leak". That was wrong, and the plan said it
because I read the retail-side finding and inferred our side without checking.
ChatLog has always been bounded (ConcurrentQueue, maxEntries default 500, with
a dequeue loop in Append). There was no leak.
The real gap is the UNIT. Retail bounds the rendered transcript by CHARACTERS —
0x2710, beheaded toward 0x1D4C at a newline boundary — while we bounded the
model by messages. Two different things: a window of 500 messages is far more
scrollback than 10,000 characters, and the message cap is a safety limit on the
log rather than a display rule.
So the budget is applied where retail applies it: on the rendered window, not
the model. ChatLog's entry cap stays as the model-level bound.
Two deliberate simplifications, both registered as CT-1 rather than left
implicit:
- ONE threshold, not retail's two. The hysteresis exists to stop retail
re-trimming an accumulating buffer on every append; we rebuild the visible
list each time, so there is nothing to damp, and a second threshold would
only make the oldest visible line jump around as messages arrive.
- Whole-line cutting rather than a newline search near an offset — our unit
already IS the line, which is what retail's newline preference is for.
Filtered-out lines deliberately do not consume budget: a line this window
filters out is not in retail's buffer at all, so counting it would mean turning
a filter OFF silently shortened the visible history.
Solution builds clean; full hermetic gate green.

Campaign CT slice A4, and the first slice of Group A that shows on screen: a
player's name in a chat line now draws green while the rest of the line keeps
its message colour.
The colour is AUTHORED, not computed. Retail keeps two parallel index-selected
colour arrays on the text element and refreshes both from the same caller index
on every append (UIElement_Text::AppendStringInfoWithFont @0x00469DE0):
property 0x1B for ordinary glyphs, 0x1D for glyphs under an open tag. Property
0x1D is read exactly the way 0x1B already was, carried on ElementInfo, and
seeded onto UiText beside DefaultColor. Measured on the chat transcript
(0x2100006F / 0x10000011) as RGB(0,178,0).
It deliberately does NOT go into RetailChatColorTable. That table is the
runtime-built per-LogTextType mapping; the tag colour is per-element authored
data, and filing it there would put it somewhere it would look right in tests
and be wrong in principle.
RunsForFragment is the load-bearing piece and is pure. Wrapping can drop the
space it broke on, so a fragment is NOT simply the next N characters of the
line — BuildLines locates each fragment in the source text to keep the span
offsets honest, and the mapper clips spans to the fragment window. A tag
straddling a wrap break is therefore split across both fragments and stays
green on both, instead of changing colour mid-word.
Two guards worth naming. A fragment containing no tag returns NULL rather than
a single-run list, so the overwhelming majority of lines keep the existing flat
draw path untouched. And an element authoring no 0x1D falls back to the line
colour, so a name never renders in a colour nobody chose.
The run/fragment contract is property-tested across every substring of a tell
line, because CT-A1's RunsMatchLine refuses mismatched runs by silently falling
back to flat text — a mapping bug here would degrade quietly rather than fail.
Solution builds clean; full hermetic gate green.
