Reviewer: Claude (Opus 4.8). Filing the strategy/vision-level critique
(for the slice-1 code-review see the companion
2026-06-28-slice-1-claude-adversarial-assessment.md already committed
in 8680f2b).
Filed but not addressed. Six strategic findings:
- S1: wedge leads with determinism (its most contestable leg)
- S2: differentiation valley between spearhead-end and capability ladder
(the load-bearing critique)
- S3: compliance paradox — regulated buyers won't move on bus-factor-1
- S4: turn-detection ownership at the tap — OpenAI Realtime has its own
server-side VAD by default; ARCHITECTURE.md says core-authoritative.
Belongs in the slice-3 (brain) spec as an explicit decision.
- S5: solo scope vs. category timing window
- S6: self-improvement loop is the actual moat, under-sold
Addressing these is strategy-doc work that warrants user signoff and
architecture pre-reading per AGENTS.md; not auto-applied alongside the
code-track fixes.
Apply findings from the Claude adversarial assessment
(docs/reviews/2026-06-28-slice-1-claude-adversarial-assessment.md)
after GLM-5.2 verification against the codebase + str0m 0.21 source.
Spec-only patches (code fixes follow as atomic commits):
- §1.2: add F5 (resource ceiling) to out-of-scope (deferred to step 5).
- §3.4: pin both str0m inputs as mandatory (Input::Receive + Input::Timeout)
and the deadline-honoring sleep semantics (Option B from brainstorming).
Without Input::Timeout, str0m's clock froze during inbound silence;
consent checks stopped; the browser tore the call down before the 60s
idle timeout (F1).
- §4.5: clarify the idle timeout keys on MediaData only. STUN/DTLS keepalives
do not reset it. Spec already said 'no RTP'; wording now makes the
intent unambiguous so the deviation cannot return (F4).
- §5.1: drop dead Channel.created_at field. The idle timeout keys on
RtcSession.last_rtp_rx, not creation time. The field was never read (F6).
- §10 (new): record the review patches lineage + cleared findings (F8, F9).
Findings F8 and F9 cleared by reading str0m 0.21 source
(packet/payload.rs:91 rebases MediaTime to the negotiated Opus clock;
RFC 7587 fixes SDP at opus/48000/2 regardless of internal rate). Cleared
with the same standard the review used for 'Browser ICE gathering'.
See AGENTS.md slice-1 boundaries — no scope additions; this is ratification
of fixes for bugs the spec already prohibited or that the dev-loop surfaced.
