M1 slice 5: amicode service — widget kernel + dashboard (6 routes) - #470
Conversation
…ported with fork-parity fixtures M1 slice 5 of #451: GET /amicode/widgets, GET /amicode/widget-frame, GET /amicode/widget-code, POST /amicode/widget-fork, GET/POST /amicode/dashboard — 6 more fork routes (21 of 31 total). Ports (verbatim, import-path renames only): widgets.ts (registry with content hashes over the 7 builtin sources), widget-manifest.ts (TOML manifest parse/validate + config sanitization), toml-lite.ts, the widgets-src/ builtin pack, widget-runtime.ts (the sandboxed frame runtime), widget-frame-html.ts (served-not-srcdoc frame with its OWN CSP header), dashboard.ts (layout merge: sanitize-never-reject, reserved-key passthrough, missing-widget marking). New parity dimension: content-type + content-security-policy headers are recorded and compared — the served frame's own policy IS part of its contract (that's why it's served, not srcdoc). HTML routes compare byte-exact; JSON routes deep-equal as before. The fork route's wall-clock date lands only in the WRITTEN fork manifest, never the response — determinism holds without normalization. Golden fixtures: 40 → 51 entries. Contract suite 54/54; full suite green; typecheck clean.

Write dashboard state atomically. Write a same-directory temporary file, then call renameSync only after the write succeeds. A partial direct write can leave invalid JSON, causing the next dashboard read to synthesize state and lose saved layout configuration.

Reject prototype-polluting keys in table headers and assignments.
BARE_KEY accepts __proto__. A table header such as [__proto__] makes the walker read node["__proto__"], which returns Object.prototype instead of undefined. The typeof check passes, so current becomes Object.prototype and every following key = value line writes onto the global prototype. Manifest content comes from widget directories on disk, so one crafted manifest.toml pollutes the whole extension process.
Use own-property lookups plus an explicit reserved-key rejection.

Harden the TOML parser’s table-header and assignment handling by rejecting
reserved prototype-polluting keys such as __proto__, and use own-property
lookups when traversing nodes instead of inherited properties. Apply this
consistently in the table-array path, regular table path, and key assignment
logic while preserving existing conflict and duplicate-key errors.

Add a timeout to bridge requests.
request registers a pending promise and never settles it if the host sends no amc:result. The widget promise then hangs forever, no amc:error is posted, and pending grows for every dropped message. A dropped or malformed host reply makes the widget appear blank with no diagnostic.
Reject after a bounded wait and remove the pending entry.

47, Update request to impose a bounded timeout for each pending bridge request;
on expiry, remove pending[id] and reject the promise, preferably posting the
corresponding amc:error diagnostic. Ensure the amc:result handling clears the
request’s timer before settling it, preventing stale timers and pending entries.

Reject oversized files before base64 conversion.
Line 68 reads the complete file into memory and creates a base64 string before upload-library can apply its server-side limit. A large valid PDF can make the widget frame unresponsive or terminate it for memory pressure.
Apply a client-side size limit before setting busy and before calling readAsDataURL. Use the same limit that the host action enforces.

What's here
Six more fork routes ported (21 of 31 total), the whole widget kernel:
/amicode/widgets— the live registry: the 7 builtin sources with content hashes/amicode/widget-frame?id=— the sandboxed frame document, served (not srcdoc) so it carries its own CSP header — that header is now a recorded, compared parity dimension (content-type + content-security-policy on every golden entry)/amicode/widget-code?id=— builtin source + hash for the preview refetch/amicode/widget-fork— fork a builtin into the user widgets dir (id rewrite + [origin] stamp)/amicode/dashboard— layout state merge: sanitize-never-reject values, reserved-key passthrough (group/view/views/scope), missing-widget marking, builtins auto-appearingPorted verbatim (import-path renames only):
widgets.ts,widget_manifest.ts,toml_lite.ts,widget_runtime.ts,widget_frame_html.ts,dashboard.ts, and thewidgets_src/builtin pack.Parity proof
Golden fixtures grow 40 → 51 entries: registry with hashes, served frame HTML + CSP (byte-exact compare for HTML routes — deep-equal for JSON), unknown-id stub, fork success / exists refusal / not_found, stored-state merge (hidden builtin + passthrough keys + missing widget + reserved top keys), save + bad-body. The fork route's wall-clock date lands only in the WRITTEN manifest, never the response — determinism holds without normalization.
