The signals-dashboard extension was missing its required screenshot asset, so it failed awesome-copilot's validateExtensionManifest (logo must equal "assets/preview.png" and the file must exist) and never materialized -- meaning the Cairn canvas would not ship to the GHCP app. Adds the 1024x1024 preview.png and the convention logo field. Validated locally: node eng/validate-plugins.mjs -> extension signals-dashboard is valid; all 70 plugins + 19 extensions pass.

The dashboard is the centerpiece — real-time agent coordination
view showing desk status, signal types, intent text, outcome
pairing with honesty gap, token usage, and stash/restore controls.
Includes all updates from the-workshop PRs #3-#7:
- Empty state guidance for new users
- Token usage display per desk
- TA partnership signals + Cairn awareness
- Intent-as-text (execution signals use descriptive text)
- Outcome signal pairing with honesty gap calibration
- Open desk button
- Subtype labels (done/checkpoint/blocked/hands-up)

The awesome-copilot validator (eng/validate-plugins.mjs:107-148)
strips .md from the plugin.json path and appends .agent.md to
find the source file. The rename to workshop-ta.md broke this
convention. Reverting to workshop-ta.agent.md so validation,
materialization, and README generation all work correctly.

- desk-open: add 'Session orientation' section explaining the

state (journal), not runtime (each session is independent).
- workshop-ta: partnership signals write to desks/_ta/.signals/

The Workshop puts long-running AI agents (desks) in the same room,
on the same work, each with its own memory and history, sharing one
workspace so you direct the work instead of relaying it.
Components:
- Workshop TA agent (room coordinator)
- Skills: desk-open, desk-journal, signal-write, bench-read
- Marketplace entry for one-command install
Install: copilot plugin install the-workshop@awesome-copilot
Complements Ember (partnership for one agent) with coordination
for many agents. Install both for the full stack.

* Add tm7-threat-model skill for valid TM7 file generation
Adds a skill that generates valid Microsoft Threat Modeling Tool (.tm7)
files using the correct WCF DataContractSerializer format, with a minimal
reference file. Includes STRIDE threat generation workflow and a checklist
of common serialization mistakes that corrupt .tm7 files.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Address PR review: sanitize reference model, fix dangling refs, move to assets
- Move example-minimal.tm7 into assets/ per repo convention (aaronpowell).
- Remove personal/corporate metadata from the reference model (Owner,
Contributors, ChangedBy domain account, project names).
- Make the reference model self-contained: add a second stencil so the data
flow and threat SourceGuid/TargetGuid/FlowGuid all resolve to real elements.
- Fix SKILL.md threat contract (KeyValueOfstringThreatpc_P0_PhOB with
b:-prefixed KnowledgeBase fields) to match the bundled reference.
- Reconcile guidance: MetaInformation/Notes/KnowledgeBase are valid schema
elements and must be preserved; only SecurityGaps/Mitigations are invalid.
- Regenerate docs/README.skills.md and normalize line endings to LF.

* Address 2nd review: correct KnowledgeBase placement, valid TypeIds, z:Id uniqueness
- Document KnowledgeBase as a top-level sibling after ThreatMetaData (not embedded)
- Update skeleton to show <ThreatMetaData/>, sibling <KnowledgeBase>, and <Profile>
- Replace TypeIds absent from the bundled KB: AzureCosmosDB -> AzureSQLDB,
HumanUser -> Mobile, GenericDataFlow -> Request
- Require z:Id uniqueness across the file in the common-mistakes checklist

font.getbbox() returns (left, top, right, bottom), so text line height must
be bottom - top (bbox[3] - bbox[1]). The label placement code used
bbox[3] - bbox[0] (bottom - left), mixing an x-coordinate into a height and
producing a slightly wrong label-box height (empirically off by 0-4px
depending on font). The debug heatmap labeling in the same module already
uses the correct bbox[3] - bbox[1], so this brings placement in line.
Port the app workspace and runtime session inventory fixes from the personal James Hub canvas into the generic Work Hub extension. This lets the cleanup and recent-session surfaces read current app workspaces before falling back to the legacy session store.

* Add APNG Studio canvas extension
APNG Studio is an interactive GitHub Copilot canvas extension for building
Animated PNG (APNG) files from frames: draw or upload frames, tune per-frame
timing and compositing, preview live, send the result to a phone by QR, and
export an animated .png.
Adds extensions/apng-studio/ with the required .github/plugin/plugin.json and
assets/preview.png, and regenerates .github/plugin/marketplace.json.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Address review feedback for APNG Studio
Security and robustness (extension.mjs):
- Reject "." and ".." project ids so canvas/action input cannot resolve
outside artifacts/.
- Bound request bodies (1 MiB JSON, 40 MiB frame upload); return 413 when
exceeded.
- Reject malformed JSON with 400 instead of coercing to {}, so a truncated
body cannot trigger destructive routes such as /frames/clear.
- Scope shares per project so one canvas cannot rotate or stop another's
share; the LAN server is shared and torn down once no shares remain.
- get_state treats hiddenFirst as active only with >=2 frames, matching the
encoder, so a single-frame project reports the correct duration.
Accessibility (web/):
- Expose Pen/Eraser state with aria-pressed and keep it in sync in setTool.
- Mark the toast as an aria-live status region.
Packaging:
- Add extensions/apng-studio/.gitignore with artifacts/ so the documented
runtime-data exclusion holds for this extension.
- Update the README install section to reference the committed awesome-copilot
extension path.
Regenerated .github/plugin/marketplace.json.
* Use "GitHub Copilot app" wording
Update the plugin description (and regenerated marketplace entry) to refer to
the host as the GitHub Copilot app.
* Address deeper review for APNG Studio
Security:
- Require a per-server access token on every loopback data/mutation request
(minted per canvas server, carried in the iframe URL, attached to every
renderer request). Static assets stay public. Blocks a local process or
cross-origin page from reading state or driving mutations.
Concurrency and durability:
- Serialize the load-mutate-save cycle per project; dedupe concurrent first
loads; write project.json via temp file + rename.
Lifecycle:
- Track SSE clients per instance and end them before server.close().
- Stop a project's LAN share only when no other panel references it.
Correctness:
- Report exact numerator/denominator total duration; handle pointercancel.
QR and accessibility:
- Place QR version bits least-significant-bit first (versions 7-10).
- Associate delay/fps/dispose/blend labels with their inputs via for=.
* Address deeper concurrency and validation review for APNG Studio
- Run assemble() under the project lock; add_color_frame renders and appends
within one lock.
- Validate uploaded frames (PNG chunk scan, size + dimension checks) before
writing; first frame stores real dimensions; CanvasError maps to 400.
- Validate move delta; clear frames in memory before deleting files.
- Route the open-handler rename through applySettings.
- Deduplicate LAN share startup; clean up if the canvas closes mid-start.
- End SSE streams before server.close(); skip dead streams in broadcast.
- Exact fractional duration; drawing surface stays >= 1px; refresh state before
re-seeding "start from last frame".
* Address review: PNG format validation, share bind, limits, a11y
- Validate uploaded frames are 8-bit RGBA non-interlaced PNGs (standard
compression/filter); reject formats the codec can't encode.
- Cap projects at 600 frames (add + duplicate).
- Bind the LAN share server to the private address, not 0.0.0.0; require a
private address and rebind when it changes while idle; build the URL from the
bound address.
- Align width/height inputs and clampSize to the 2048 maximum.
- Size the drawing surface by width + aspect ratio for narrow panels.
- set_frame with an unknown frameId returns a validation error.
* Address review: encoded-byte budget, timing modes, id keys, load errors
- 256 MiB aggregate encoded-byte budget (add + duplicate); per-frame size
tracked and backfilled on load, so a frame count alone no longer bounds
assembly memory.
- Frame timing is one exclusive mode (delayMs | fps | delayNum/delayDen);
combinations are rejected instead of producing hybrid delays.
- Collision-resistant project storage keys: safe ids are used verbatim (existing
projects still load) and only unsafe ids get a hash suffix, so "foo/bar" and
"foo?bar" can't share a directory.
- Load only treats a missing file as a new project; other read/parse errors
surface instead of silently overwriting real data.
- Share server binds to a real LAN interface (skips virtual/VPN/container,
prefers physical NICs and common ranges).
- Generated export names get millisecond + random suffix to avoid same-second
overwrite.
- PNG validator accepts the encoder's Uint8Array so agent solid-color frames
aren't rejected.
* Address review: crash-safe frame writes, server startup, APNG first frame
- Write the PNG before mutating project metadata on add/duplicate, and delete
after persisting, so an interrupted disk op can't dangle a reference or
advance unsaved state.
- Evict a project from the in-memory cache if its save fails, so a transient
write error can't desync the live session from disk.
- Reject on the loopback server's listen error and drop a half-initialized
instance so startup failures clean up and can retry.
- Normalize APNG dispose_op PREVIOUS to BACKGROUND on the first animated frame
(spec requirement).
- Release decoded ImageBitmaps after use so a large upload batch doesn't retain
native image memory.
- Surface otherwise-silent async UI failures via a toast; check the state
response is ok before parsing it.
