Subject: [PATCH 01/13] fix(ui): keep Selection details inside the galaxy stage

The Galaxy workspace gave .atlas-galaxy no position, so the absolutely
positioned Selection details box was placed against the workspace grid
that also holds the chat column. With chat open it covered the chat
input and swallowed clicks on Send. The galaxy stage is now the
containing block; fullscreen keeps its own fixed box.

Subject: [PATCH 02/13] fix(ui): describe Galaxy selections to the local agent
 as readable facts

The prompt for a Galaxy selection was a dump of JSON paths: snapshot,
view, generation, rendered sizes and omission paths. Relationship items
were cut to 24 before anyone looked at their direction and then to three
before the budget applied, so "who calls JSONBAgg" reached the model with
one outgoing INHERITS edge and no caller.

GalaxyPanel now classifies every scope edge against the roots first and
publishes incoming and outgoing groups per edge type with complete
counts and the related names by file. The agent prompt states the
selection with kind and file:lines, both sides in words, the scope
(depth, direction, filters) and its completeness. Names are listed until
the budget ends and followed by an explicit "+N more"; the packet
reports how many it could name. Other evidence kinds keep the generic
formatter.

Subject: [PATCH 03/13] fix(ui): answer caller and callee questions from the
 loaded graph

"Who calls JSONBAgg?" got no caller: the model saw one relationship,
decoded greedily without repetition controls and repeated one line until
the 512 token budget ran out.

Caller and callee questions about the current Galaxy selection, in
English or German, are now answered without the model from the loaded
scope: every edge type with its complete count, the related names by
file and an explicit "+N more" beyond the evidence bound, CALLS first.
The answer says when the scope does not follow that direction or is
still loading, instead of reporting no callers.

For everything else:
- manual chat gets a repetition penalty and an n-gram block as well;
  the n-gram block now checks the answer against itself only, because
  counting the prompt forces quoted names and paths off course
- the worker reports why generation ended and the dock marks answers
  cut at the output limit as "Shortened (token limit)"
- a scope larger than the prompt can name shows "<nodes> nodes /
  <edges> edges: too large for the local <model> model; showing <n>"
- history is trimmed oldest first to the input limit, with a note,
  before the request is refused

Subject: [PATCH 04/13] fix(ui): reuse selection explanations and wait for
 complete scopes

Every return to a selection showed "Explaining selection..." and ran the
model again: there was one explanation slot, and the selection key held
the whole evidence text, so counts and the loading state changed it
while the scope loaded. An explanation could also start on the preview
and describe the state before the expansion.

A Galaxy selection is now identified by project, workspace, the selected
scope, direction, edge types and depth. Finished explanations are kept
per selection (at most 32) and shown again on return without a new
generation; "Explain again" replaces the entry. An explanation starts
only once the scope is complete; until then the card says it is waiting.

Subject: [PATCH 05/13] feat(ui): set and keep local agent token limits per
 model

The agent configuration offered model, automatic explanations and
history only, and the model choice and the automatic flag reset on every
reload.

It now has an input (context) and an output limit for the selected
model, bounded by the model policy: the answer stays within the model's
output ceiling and question plus answer within its browser context.
Limits, the chosen model and "Explain selections automatically" are
stored in this browser under a versioned key and validated on read, as
the view preferences are. Manual chat uses the limits for its prompt
budget and asks the worker for that many output tokens; automatic
explanations keep their short budget but never exceed the limits.

Subject: [PATCH 06/13] feat(ui): show the local agent as a robot with a status
 lamp
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The header read "Agent active · Qwen2.5 Coder 0.5B" next to the chat
toggle. It is now a robot icon drawn on the same grid as the chat toggle,
with the status lamp at its corner; a click still opens the agent
configuration. The state and the model name move into the tooltip and
the accessible name, and the model is chosen in the configuration.

The header's agent and chat labels now come from the workspace strings,
which removes the seven hardcoded chrome strings the style gate found in
AtlasChrome.tsx.

Subject: [PATCH 08/13] fix(ui): count an answer that ends on its last allowed
 token as finished

The worker inferred "length" whenever the answer used every allowed token.
Transformers.js also hands the end-of-sequence token to the streamer, so an
answer that ended exactly on the limit was reported as cut and the chat
showed "Shortened (token limit)". The worker now remembers the last token
and reports "length" only when it is not an end-of-sequence id of the
model or tokenizer.

From d53b008db84ba4029e9858cce6eca2b06527c215 Mon Sep 17 00:00:00 2001
From: Bernhard Jackiewicz <bj@techport.io>

Subject: [PATCH 09/13] fix(ui): keep large Galaxy scopes whole for the local
 agent

The selection snapshot has a 16,000 character budget. Roots came first
with up to 1,200 characters of documentation each, so in a large scope
the copy cut whole relationship groups, the symbol totals and names. The
answer then said "to 0 symbols", dropped edge types and still called the
list complete. When a side was dropped entirely the reader fell back to
the old path dump, caller questions went to the model and the explanation
key lost its waiting gate.

GalaxyPanel now builds its evidence through galaxyScopeEvidence. Root
documentation stops at the 300 characters the readers use. Counts come
before names, and the names of all groups share an explicit budget, so a
scope fits the snapshot. The reader recognises a Galaxy scope by its
identity and depth, accepts a missing or cut side and reads the snapshot
omissions. The prompt and the listed answer then say that relationships
were left out instead of claiming a complete list.

The capacity note now appears only when the prompt could not name every
symbol the snapshot carried. The snapshot's own bound of 24 names per
group is no longer reported as too large for the model.

Subject: [PATCH 10/13] fix(ui): list callers only for the selected symbol and
 only on list questions

Without a detected subject every caller question counted as one about the
selection, and subjects were found only for camelCase names. "Who calls
get_queryset?" or "Wer ruft as_sql auf?" therefore listed the callers of
the selected JSONBAgg. The question is now read around its verb, so
snake_case and single-capital names are subjects too, and only a subject
that names the selection, one of its roots or "it"/"this" gets the graph
list.

The direction patterns also missed common phrasings and read "Welche
Funktion ruft X auf?" as a callee question. Singular "welche <Nomen> ruft
X auf", "rufen ... auf", "wo wird X aufgerufen", "which/what <noun> call
X" and "where is X called" now ask for callers; a plural noun with "ruft",
"was ruft" and "wird von X aufgerufen" ask for callees. Why, how, what-if
and explain questions go to the model even when they mention callers.

A listed answer now offers "Ask the model", which sends the same question
with the same evidence as a fresh request and replaces the list.

Subject: [PATCH 11/13] fix(ui): release the local agent when another tab picks
 another model

The model choice is stored in the browser and follows storage events, but
only this tab's select released the worker. A model chosen in another tab
changed this tab's model while the old worker stayed loaded: the dialog
called the new model "Loaded", turns recorded the wrong model and the new
model's limits ran on the old worker. The dock now remembers which model
its worker was created for and releases it, and clears the explanation
cache, whenever the chosen model differs.

Subject: [PATCH 12/13] fix(ui): let the input limit decide how much evidence a
 question carries

The input limit only capped token counting. Manual chat always started
from 3,200 characters of evidence, so raising the limit never showed more
of a scope while the capacity note still blamed the model. The first
evidence budget now follows the configured limit (2,048 tokens still give
3,200 characters) and shrinks from there as before.

The output field used step 64 with a minimum of 32, which made the
default 512 and values like 128 or 256 step mismatches and kept the
arrows from reaching 512. It now steps by 32; the input field keeps 64.

Subject: [PATCH 13/13] fix(ui): retire a cached explanation when its scope's
 evidence changed

The explanation cache is keyed by selection and scope shape only, so that
a scope that is still loading finds its explanation. After a re-index of
the same project in the same session, returning to a selection still
showed the explanation of the old graph. Every cached explanation now
keeps the id of the complete evidence it was written from. When the same
selection completes with other evidence, the entry is dropped and the
selection is explained again; while it loads, the cached text stays.
