The live socket never made a REST call, so the seven-day refresh
token expired while the chart still looked fine. A deploy then
could not log in. Ping user preferences every six hours, and when
the grant is already dead offer a one-click reconnect that writes
the token on the existing callback.
Alerts get a number, assigned server-side and shown in both the push and the
Events list, so a notification on a phone can be matched to a row on a screen
when several fire together. It could not come from the browser: that counter
restarts on reload and differs between tabs. It is persisted next to the
cooldown state, because numbering restarting after a deploy would collide with a
phone's existing notification history — which changed that file from a list to
an object, with the loader still reading the old shape.
Pushes now carry a timestamp in the configured zone rather than the server's.
ALERT_TIMEZONE defaults to America/Chicago; containers run UTC, and a push
reading 02:14 to someone seeing 21:14 costs a translation every time. The
browser already formats its own times locally and is unchanged.
Confluence zones are one line each, ordered by price rather than by proximity,
so the list reads top to bottom the way the chart does and all of them fit on
screen — sixteen zones in 394px, about 25px each, where each previously took a
four-line block. Ordering is a display concern only: the server still returns
them nearest-first, which is what the alert path wants.

P0 from docs/async_refactor.md. The mutating routes are sync `def`, so FastAPI
runs them in a threadpool, and they reach Runtime.broadcast through
rebuild_levels — writing asyncio.Queue directly from there. That queue is not
thread-safe: it wakes a consumer by resolving a Future, which only the loop
thread may do. A dropped wakeup means a drawing made in one browser does not
reach another until the next market tick.
broadcast now posts through call_soon_threadsafe when it is off the loop, and
publishes directly when it is on it, so the stream's own path pays nothing.
Worth being straight about the tests: the race is timing-dependent and did not
reproduce in twenty attempts — a foreign-thread put_nowait usually lands in the
ready queue before the loop sleeps, and a tick every second covers the rest.
Even asyncio's debug thread-affinity check stays quiet unless a consumer is
parked on the Future at that instant. So the tests assert the contract rather
than provoke the failure: a broadcast from a worker thread must go through
call_soon_threadsafe, one from the loop must deliver synchronously, and both
must arrive.
Also adds the loop-lag probe, which reports scheduling drift as loop_lag_ms on
/api/status. It found P1 on its first run: 19,441ms worst against 1.5ms in
steady state, which is seeding blocking the loop. "The chart feels laggy" is now
a number.

The trendline snap indicator was 66 pixels out, and so was every other overlay.
Lightweight Charts reports coordinates from the plot area's origin. The chart
element also contains the price scales, so enabling the left scale for the daily
labels moved the plot 66px into the element — and each overlay positioned with
left: against the element inherited that error twice over. The cursor's
element-x was read as a plot-x, resolving a bar about 66px right of the pointer;
the indicator was then drawn at that bar's plot-x interpreted as element-x,
landing 66px left of where the bar is painted. Neither near the cursor nor near
the bar, and scaling with zoom — two bars at 30m, a dozen at 1m — which is why
it read as random rather than as an offset.
Every diagnostic number agreed with itself the whole time, because dot_y,
expected_y and bar_low_y all come from the same API and shared the same wrong
origin. Instrumentation cannot see a systematic error in its own frame of
reference; what found this was comparing canvas.width to element.clientWidth and
getting 0.894.
Overlays now live in one container positioned over the plot canvas and inherit
plot coordinates untranslated — snap dot and label, comments, anchor handles,
preview line, tooltip, price tag, context menu — and eventPoint subtracts the
same offset so a pointer position and a chart coordinate mean the same thing.
The container follows the plot on resize.
Verified in page pixels rather than through the coordinate API: with the cursor
placed 30px below a known bar's low, the dot lands 30px above the cursor, on
that low, labelled 7789.00 L against a bar low of 7789.
Device pixel ratio, viewport size, resize desynchronisation and the chart
scrolling under the gesture were each measured and ruled out before this. The
e2e helper computed expected times from element-relative x, the same mistake in
the tests, and is corrected here.

The snap dot said where an anchor would land but not what it was, which made
"the dot is in the wrong place" and "the dot is on the wrong bar" impossible to
tell apart from a screenshot. It now carries a label with the price, whether it
is a high or a low, and the bar's time.
AGENTS.md gains the environment fact this session kept rediscovering: the agent
runs on a remote machine over SSH while the user's browser runs on another, so
headless runs here render on different hardware at a different size and pixel
ratio, and "it passes in my headless run" is not evidence the user's problem is
fixed. Three consecutive reproductions passed server-side while the chart was
unusable on the user's screen. When a visual bug will not reproduce, match their
viewport and deviceScaleFactor explicitly — and prefer putting the numbers on
screen over asking for another console paste.
Device pixel ratio is ruled out for the current trendline complaint: the
bottom-sweep check lands 115 of 115 at 1600x1000 and at 1900x1400 with ratios of
1, 1.25, 1.5 and 2.

The header spent a whole line on a "CME FUTURES" eyebrow that told you nothing
the chart didn't — it only ever shows /ES. Dropping it takes the header from
64px to 44px and hands the space to the chart. The title becomes /ESsence.
AGENTS.md records the rules worth keeping, chief among them that a bug should
prompt the question of whether a unit test could reasonably have caught it —
written when the answer is yes, skipped when it is a rendering or data-source
quirk, and named after the failure rather than the function.
It is AGENTS.md rather than CLAUDE.md deliberately: opencode's instruction
loader walks up looking for AGENTS.md only and never reads CLAUDE.md, and the
ask-opencode skill asks the calling agent to distil house rules by hand rather
than forwarding a file. CLAUDE.md is a symlink to it so both tools resolve to
one source of truth.

Two faults, one of them a regression that reached production.
Making a pending anchor always win fixed a twitch on the second click stealing
the start point, and broke the opposite case: a genuine press-drag begun after
an abandoned click was hijacked by that stale anchor, so the line started far
from where the drag did. A single threshold decides now — 12px of travel between
press and release makes a gesture a drag, wide enough to survive a twitch on a
deliberate click and unambiguous for a real one. A drag abandons any half-placed
anchor instead of adopting it.
The crosshair was also lying. Lightweight Charts defaults to CrosshairMode.Magnet,
which snaps the crosshair to the bar's close, so hovering beside a bar's low drew
it mid-bar and a correctly-placed anchor looked wrong. Measured: aiming 4px above
a bar low anchors at the low, 7773, not the close, 7773.25 — the placement was
right and only the feedback was wrong. Arming a tool switches the crosshair to
Normal, and a snap dot now marks the exact point the anchor will use, coloured by
the side that extreme implies.
Verified in a browser across all four paths: two clicks with a twitch on the
second, an abandoned click then a real drag, a plain press-drag, and hovering.
Each starts where it should and lands on a bar extreme, and the stale anchor is
no longer adopted.

Snapping now always lands an anchor on a bar extreme, and which extreme it is
decides the side — a high is resistance, a low is support. That left the Side
dropdown unable to affect the result: it was overridden on every drawn line.
It now appears only when "Snap to highs/lows" is off, the one case where there
is no extreme to infer from. With snapping on the row reads "Side auto" instead,
so the behaviour is stated rather than implied by a control that does nothing.
An "Auto" option in the dropdown would have been the same no-op wearing a label.
Verified in a browser both ways, and that the inference itself holds with the
dropdown left on its default: drawing above the candles yields resistance
snapped to the bar high, drawing below yields support snapped to the bar low.

A comment is a ManualLine with kind="comment", so it inherits persistence, the
shared drawing-number sequence, the list, filtering and deletion rather than
needing a parallel set of endpoints. The rule that must never bend is that
ManualLineStore.levels() excludes them: a comment reaching the level list would
join a confluence cluster and push a phone notification about a piece of text.
It is created with armed=False, and PATCH returns to_dict() rather than
to_level() for a comment, so nothing is ever handed a level-shaped comment.
Three tests cover the exclusion, the shared numbering and the kind derived for
drawings saved before comments existed.
Pinned comments carry anchor_t and anchor_p and travel with the chart; floating
ones carry x and y as fractions of the pane, hold their place through any zoom
and can be dragged. They render as DOM rather than canvas because they hold
arbitrary text, collapse to a numbered dot, and a floating one must ignore the
time scale entirely. A pinned comment scrolled out of view parks on the edge it
left, pointing back toward itself, so it never simply disappears.
Lines & levels becomes Drawings, filtered by type and by text. The text match
covers the label, the kind and the #number, so "comment", "cpi" and "7" all
narrow the list, and Delete acts on whatever the filter shows — which is what
makes deleting by type or by string one button.
Verified in a browser: placing a comment renders it at the click, clicking it
collapses it, scrolling away parks it on the edge, a floating one holds its
pixel position through a 300-bar scroll, and the filters cut 3 rows to 1 by type,
1 by text and 0 for a miss, with no console errors.

The right column ran past the viewport with nothing selected. Five changes, none
of which remove functionality.
The five daily MA periods now share one line. 10px gaps and a 22px indent had
pushed 200 onto a row by itself; nowrap, 7px gaps and 12px boxes fit all five
with room to spare. Auto trendlines becomes a parenthetical on the Manual lines
row instead of owning one — it is disabled until M8, so a full row overstated
it. The alert log becomes a collapsible section like Confluence zones, closed by
default with its count in the summary, so activity stays visible while it is
shut and the banner, sound and phone push are untouched.
Tools becomes a collapsible section as well, open by default, and each tool's
panel is now bound to armedTool: the label, colour, width and side controls
appear only for the tool actually armed. armTool already toggled and allowed one
armed tool at a time, so the panels follow it with no new state.
Layers moves above Tools and starts collapsed. The zeroed top margin moves from
a Tools-specific class to .sidebar-section:first-of-type, so reordering again
cannot reintroduce a gap above the first section.
Measured with nothing armed: 1110px of content down to 900px, inside the
viewport rather than past it. Verified in a browser — arming each tool reveals
that tool's panel and no other, disarming hides both, Tools opens by default,
Layers starts closed and still lays its periods out on one line when opened.

Three cuts, so the right column keeps more of itself for the chart.
The five daily MA periods now sit on one line. 10px gaps and a 22px indent had
pushed 200 onto a row by itself; nowrap, 7px gaps, a 4px label gap and 12px
boxes fit all five with room to spare, verified as five labels sharing one
offsetTop and no horizontal overflow.
Auto trendlines becomes a parenthetical on the Manual lines row instead of
owning a row. It is disabled until M8 builds it, so a full row overstated it.
The alert log becomes a collapsible section like Confluence zones, closed by
default with its count in the summary. Closed by default is the point — leaving
it open would reclaim nothing — and the count keeps activity visible while it
is shut, with the banner, sound and phone push unaffected either way.
