Adds a version-evolution capability to the Artifacts pane:
- Evolution chain: LCS-based diff across successive versions of the
same logical artifact; when a blob is missing, the chain honestly
surfaces a placeholder rather than fabricating diff content.
- Board / Timeline tab switcher on the Artifacts page.
- Auto-grouping into 5 kinds so the Board reads at a glance.

Merged as source-repo test-real @ 7279870 (with lane-side conflict
resolution against test-real @ c1d93aa: style.css tail-append union;
independent of Lanes C/A/D CSS sections).
Test suite: 1727/1727 pass (+23 over Lane C+A+D baseline of 1704).
Follow-up L-3 (in upstream ledger): runtime ArtifactServer to grow
a snapshot store so the "missing blob" fallback becomes rare.
Architectural refactor unifying three previously-independent pages
around a single shared event-log model:
rubric-fusion-model.js — the shared model. One log of scored
events keyed by (rubric, runtime, timestamp), plus a small set
of derivations (recent-scores window, per-rubric aggregates,
per-runtime rubric grid) that all three views subscribe to.
rubric-fusion-seed.js — fixture seed used by tests and the
isolation-machine screenshots below.
The three page views:
Rubrics — now leads with a hint card (recent pass/fail streaks,
stalest rubric) and a stats strip (7-run rolling pass rate,
latest score, delta vs. previous). Rubric list is unchanged.
Growth — rewritten. The old compact-window event feed is gone;
the page is now a pure SVG time-series curve over the event
log (score-y × time-x), with per-rubric coloring and a
hover-time tooltip. -420 lines of the old feed → +630 of the
curve renderer.
Runtime — adds a "Rubric grid" tab next to the existing Status
tab. Grid is one row per rubric × one column per runtime;
cells are pass/fail/unrun, click-through to the raw event.
Wiring is careful about the five hot zones the parallel lanes are
each touching (nav / chat / context / trace / artifact) — Lane D
stays entirely inside rubric/growth/runtime and their shared model,
so this composes with the C/A lanes without stepping on their
finishTurnContainer or chat-triple regions. style.css conflict
against the C+A combined append was tail-append vs tail-append and
resolved by concatenation (brace balance verified).

HEAD.
Adds a three-layer view to the Chat pane:
- List view — turn cards get colored left-edge by role/state
(user/assistant/tool/error), replacing the flat
monochrome stack; readable at a glance for long
sessions.
- Side drawer — a right-side collapsible panel opened via the
Details button on any turn; shows the raw payload,
annotations, and jump-links to the trace tri-view
without leaving the chat.
- Session Graph— a top-level SVG view of the whole session's turn
graph (user → assistant → tool chain → subagent
branch); zooms out from the linear list to the
session's structure.
Renderer wiring is additive: the three new modules mount into two
new hook points in index.html; turn/start now emits data-turn-id
so the drawer can round-trip. finishTurnContainer keeps its Lane C
signal-chip pass and picks up drawer wiring at the tail — the two
tails are independent and compose cleanly.

Known non-blocking niceties, tracked as follow-ups (out of scope
for this commit):
- Details button and existing Context Rail both target the
right-side slot; a small drawer-mutex pass unifies them.
- Session Graph fixture includes an extra subagent turn beyond
what the list view shows.
Adds a small signal-detection layer over trace payloads and surfaces
three kinds of semantic signals inline in the trace tri-view (Timeline
/ Graph / turn footer chips) so a researcher can spot repetitive
tool-call loops, redundant identical calls, and plan-completion beats
without hand-scanning the raw log:
- loop-detected — three or more repeats of the same tool.method
signature inside a window, badge in Timeline gutter
+ colored ring on the Graph node
- redundant-call — identical (tool, arg-hash) call twice without any
state change in between, badge + subdued styling
so it stays advisory not alarmist
- plan-* chips — plan/subplan step-complete beats surfaced above the
assistant body in the turn footer, wired through
the finishTurnContainer tail
Pure rendering; no wire-format changes needed on the runtime side —
signal detection is fixture-driven off the same payload the tri-view
already consumes. Companion RFC L-2 in docs/upstream-ledger.md asks
the runtime to emit these signals natively rather than deriving them
in the shell, so once L-2 lands the shell will consume upstream signals
and this detector becomes a fallback.

Adds the 3.6 MB take-3 walkthrough mp4 that README already references
via a poster image, and replaces the "coming in a follow-up commit"
placeholder line with a real link (poster now click-through to the
video, caption points at the same file).

No source or config changes; the shell tree from a3ca492a is byte-
identical to what it was, this commit just fills in the recording
slot the previous docs commit deferred.
Expanded README landing page for first-time cloners: Pages & Features
guide walks through each of the 14 UI surfaces (chat, trace timeline,
subagent panel, context surface, rubrics, plugins, compaction, budget,
etc.) with 2-4 sentences on what each page shows and why it exists.
Feature highlights section lists 10 concrete affordances a plugin
author or researcher would want to know are there.
Quick Start rewritten for the cold-clone path:
- two-step pnpm install (repo root for tsx, then examples/desktop for
Electron) — resolves the P0-5 install failure a fresh clone hits
- HARNESS_DEV layouts documented: in-repo (default when cloning
deepseek-harness), sibling deepseek-harness-dev/ (original dev
workflow), DSH_DEV_ROOT env (custom layouts)
- .env locations described relative to the runtime root rather than
hardcoded paths
- Profiles table reordered with stdio-echo first (keyless, works on
master); daemon-echo and daemon-vibe-echo marked 'Not yet available
on master' with a note pointing at the integration worktree
Facts-only tone; the only referenced assets are 01-overview.png,
03-chat.png, and video-poster.png in docs/readme-shots/ — all present
in the release tree.
Minimal Electron shell over the DSH JSON-RPC runtime — a first-look at
what a ChatGPT.app-style host on top of the DeepSeek Harness looks
like, with the harness's normally-invisible internals (trace timeline,
context surface, subagent tree, compaction, plugin registry, rubrics)
brought forward as first-class UI surfaces so plugin authors and
researchers can see what the agent is actually doing.
Runs against three keyless-to-live profiles (stdio-echo works on
master out of the box; daemon-echo / daemon-vibe-echo activate once
the daemon-demo lands; stdio-deepseek and daemon-vibe hit the real
DeepSeek API when you supply a key). HARNESS_DEV auto-resolves to the
in-repo runtime when this shell ships under examples/desktop/, so a
fresh clone launches without config; env DSH_DEV_ROOT overrides for
custom layouts, and a sibling deepseek-harness-dev/ checkout is the
original dev workflow.
Cold-clone gate (P0 fixes for first-time-clone usability):
- HARNESS_DEV: 3-candidate resolver (env → walk-up in-repo marker →
sibling), unit-tested via mock fs so ordering is locked without
needing either real layout on disk.
- config yml leaves rewritten at assemble time so the sibling-clone
paths (../../deepseek-harness-dev/examples/echo-agent/…) become
the in-repo paths (../../echo-agent/…) in the released tree —
source yml stays usable for local dev, released tree ships a
working shape.
- pnpm-workspace.yaml allowBuilds.electron = true (was placeholder).
- missing-key card in stdio-deepseek offers a one-click switch to
stdio-echo (the keyless profile that works on master) rather than
daemon-echo (blocked on the not-yet-shipped daemon-demo).
- assemble-oss-release.sh rewrites the source-side breadcrumb name
'dsh-desktop-demo' → 'dsh-desktop' for the released package.json.
FOUC guard on the onboarding gate (41fc5df carried) keeps the
first-launch splash from flashing before the runtime probe finishes.
Test suite (1634 tests in source, 3990 in the runtime repo) covers
resolver ordering, renderer classifiers, trace timeline shape,
compaction diff rendering, rubric parity, and the missing-key
onboarding paths.
