The timing compiler scanned raw HTML with tag regexes that weren't
comment-aware, so a comment or script merely mentioning `<video>`/`<audio>`
was rewritten as a real element — injecting id/data-start/data-hf-auto-start
into the comment text. That phantom attribute then tripped the probe stage's
substring check (`html.includes("data-hf-auto-start")`), launching an
unnecessary browser probe on every render with an unexplained empty reasons list.
- Mask comments, <script>, and <style> regions before the tag scan, then
restore them verbatim (compileTimingAttrs, extractResolvedMedia).
- Replace the probe's substring match with a DOM query
(video[data-hf-auto-start]) and add "auto-start video(s)" to the reasons list.
* feat(lint): flag dir="rtl" on <html> as a confirmed silent render failure
Two independent reports diagnosed the same exact bug: dir="rtl" (or any
non-ltr value) on <html> renders correctly in preview/snapshot but
produces a fully blank/black video from render, with no other
lint/validate/inspect check catching it - output file size (far smaller
than expected) was the only tell for both reporters. Both independently
confirmed the same fix: drop dir from <html>, keep lang, and scope
direction: rtl to individual text-containing elements via CSS instead.
Could not empirically verify the render pipeline's own root cause in this
session (headless Chrome screenshot capture is unreliable in this
sandboxed environment - even a baseline, non-RTL capture timed out), so
this ships the safe, already-confirmed advisory rather than guessing at a
runtime fix. Both reporters explicitly asked for exactly this: "deserves
a lint rule or render-time warning."
* fix(lint): only flag valid non-ltr html dir values
* feat(cli): emit sign-in lifecycle telemetry
The CLI tracks command and render lifecycles but emits nothing for
`auth login`, so sign-in outcomes are invisible on the observability
dashboards — a completed sign-in, an abandoned browser flow, and a
rejected key all look identical (absent). This leaves a blind spot in
the same funnel the render events already cover.
Add three events mirroring the existing `trackX` pattern:
- auth_login_started (method: oauth | api_key)
- auth_login_completed (method)
- auth_login_failed (method, reason)
`reason` is a fixed low-cardinality enum (flow_error / no_credential /
rejected / invalid_input). No token, key, identity, email, or free text
is ever attached — consistent with the existing anonymous telemetry and
the `telemetry disable` opt-out. Wired into both the OAuth and
--api-key paths in `auth login`, with unit coverage for the new events.
* fix(cli): close sign-in telemetry funnel dropout gaps
Follow-up so `started` reconciles to `completed + failed` on the common
abandonment paths, which the first cut missed:
- Interactive prompt cancel (Ctrl-C) now surfaces as a throw that the
single catch in the api-key path records as `aborted`, instead of a
bare exit with no event.
- A stdin read that times out in non-TTY `--api-key` mode now records
`aborted` before the error propagates, rather than exiting silently.
- OAuth split: a timed-out browser callback (user closed the tab) is
tagged `flow_timeout`, separated from real `flow_error` (IdP/network),
since the walk-away timeout is the dominant non-error dropout.
Also pre-plumb an optional `distinctId` on the three trackers, mirroring
trackRenderComplete/trackRenderError. Unused today; it lets a later
identity-level attribution be a one-line callsite change rather than a
signature sweep. Coverage added for the new reasons and forwarding.
