PR builds can't pull ci-base (no GCP secrets on pull_request events).
dev.yaml falls back to committed bin/ + runtime/ instead.
Extracted from ci-base:latest (sdk-release.yaml run 1411).
- dev.yaml: build + local docker smoke test only (no push, no deploy)
- stage.yaml: build + push + deploy to marketing-stage + smoke test (stops here)
- deploy.yaml: add HTML placeholder touch step before docker build
Proper human gate between stage and prod: the stage→main merge decision.
A real attacker probed /api/share earlier today with <script>alert(1),
<iframe src=evil>, <img onerror>, <a href="javascript:...">, and a
<form action="/steal"> payload. Nothing executed because the chat
bubble at /share/<id> renders the served HTML inside marked.js's
already-escaped output, but the prior denylist sanitizer was fragile:
- It comment-wrapped dangerous tags ("<!--script>...-->") which a
literal "-->" inside an attacker-supplied attribute value can close
early, re-exposing the original payload.
- It renamed on*= attributes to data-x-on*= which left attack
indicators visible in the served HTML.
- It was a denylist; every new attack vector required a code change.
- It didn't validate <a href> URL schemes properly.
The replacement is a runtime-level state-machine allowlist parser
(foundation/el af480f6: el_html_sanitize). The product just specifies
the JSON allowlist of allowed tags + attributes; the runtime drops
everything else, validates href/src URL schemes (http/https/mailto/
fragment/relative only), and drops whole subtrees of script/style/
iframe/object/embed/form regardless of the allowlist.
Phase 4 of bl-dc55ae07: deletes sanitize_share_html (main.el) and
gal_sanitize_html (gallery.el); replaces 3 call sites with
el_html_sanitize(html, allowlist). Defines default_share_allowlist
in main.el and the identical gallery_share_allowlist in gallery.el
(separate bindings to avoid a forward-reference at build-concat
order — gallery is concatenated before main).
Phase 5: migrations/20260502185500_backfill_resanitize_share_cards.sql
nulls answer_html for any share_cards row older than 1 hour. Applied
via the Supabase Management API; 0 rows in scope (the column was
added today and existing rows pre-date its first write).
Also fixes an orthogonal duplicate-symbol bug: unix_timestamp() was
defined in both dist/web_stubs.c and the runtime (the latter is a
recent runtime addition picked up by the runtime sync). Removed the
stub.
Backlog: bl-dc55ae07
Build pipeline
- build-stage.sh replaces the old in-Dockerfile bootstrap.py path. Host
pre-compiles src/*.el into dist/main.c via the canonical native elc at
foundation/el/dist/platform/elc and applies the stub-decl sed before
docker buildx runs.
- Dockerfile.stage drops bootstrap.py + python3 from the builder stage
and just runs cc on the host-supplied dist/main.c.
- Pre-rendered HTML shells under /srv/landing/ are now chowned to the
landing user so the El page-builder's fs_write at startup can rewrite
them — without that, post-COPY edits never reach the served HTML and
the served page stays as the stale build-time fallback.
Chat restore
- session.verified + session.verifiedAt persist through localStorage so
a return visit within 24h skips the Turnstile gate and lands directly
in the restored conversation.
- restoreOrGreet() is the single source of truth for what shows up in
the message pane after the gate clears: replays prior messages with
skipSave, else drops the canned hello once and remembers it.
- applyVerifiedDom() hides the gate / reveals the chat row, called both
from the verified-on-load path (DOMContentLoaded if loading, else
immediate) and from the Turnstile callback.
- neuronDemoReset clears verified + verifiedAt so the gate returns next
open.
Extracted JS assets (src/assets/js/*.js + manifest.json) and the
extract-js.py helper land here too — they match what the new build-stage
flow produces and removes the inline <script> blobs from the served HTML.
