chore(docs): bump next to 16.3.6 by pranaygp · Pull Request #4395 · vercel/workflow

pranaygp · 2026-09-24T23:18:53Z

Routine dependency bump: the docs app's Next.js pin moves from 16.3.3 to 16.3.6 (patch, same minor).

Lockfile churn

The diff is larger than the one-line pin because re-resolution dedupes two things, both of which shrink the tree:

sharp — next's optional image-optimization dependency collapses onto the 0.35.4 copy already in the workspace, so sharp@0.35.3 and its @img/sharp-* / @img/sharp-libvips-* platform packages drop out entirely.
@workflow/web — it depends on geist, which peer-depends on next without @workflow/web declaring next itself. That unmet peer re-points from 16.3.4 to 16.3.6. No package.json in packages/ changes, and the pinned 16.3.4 in packages/next and the nextjs-* workbenches is untouched.

Verification

pnpm --filter docs build passes: all routes prerender, including the sitemap.md and llms.mdx agent-discoverable routes.

The changeset has empty frontmatter — docs is in .changeset/config.json's ignore array, so no package is released — matching the previous docs-only Next bump.

Routine patch bump of the docs app's Next.js pin from 16.3.3 to 16.3.6. The lockfile churn beyond the pin itself is dedupe: next's `sharp` optional dependency collapses onto the 0.35.4 copy already in the tree (0.35.3 and its `@img/*` platform packages drop out), and `@workflow/web`'s unmet `geist` peer on next re-points at 16.3.6. `pnpm --filter docs build` passes.

⚠️ Flaky E2E Tests (passed on retry)

These tests failed at least once and passed on a retry. A recurring entry here is a real race worth investigating.

fires constructor + stream callbacks in order with step data (sveltekit · vercel-prod / vercel / node / production)
string instructions are passed to the model (nextjs-webpack · vercel-prod / vercel / node / production)

🛠 Infra Events (absorbed by the harness)

Platform anomalies the e2e harness detected and worked around (e.g. a run the queue never picked up, replaced by a fresh run). Clustered timestamps indicate a backend blip; a steady drip indicates a platform issue worth escalating.

ℹ️ Metric definitions & methodology

_{Streams: first-chunk RTT (the stream-open path, before any buffering/backpressure), CRTT percentiles, and worst delivery stall (CDV max). Cells are medians across iterations; per-run values in the artifacts. No 🔴/🟢 marks until targets attach.}

_{The collapsed STSO distribution section above buckets every step gap, split inline (same warm process — pure framework overhead) vs queue-hop (fresh process — dispatch, reinit, replay). █ = main, ┃ = this run, ░ = fill.}

_{The collapsed CRTT drill-down: per-variant RTT histograms (fixed log bins, · = empty) and mean RTT/positive-CDV profile lines over stream progress and chunk size. Histograms, avgs, and profiles merge exactly across runs; p50–p99 are percentile-of-percentiles. Per-index rows live in the artifacts.}

_{Best/P75/P90/P99 deltas compare against the most recent benchmark run on main at the time of this run. 🔻 flags a delta worse than +15%, 💚 one better than −15%.}

_{Metrics — TTFS: time to first step body (in-deployment start() → first step body) · Fan-out TTFS: fan-out time to first step (in-deployment start() → first of the parallel step bodies to complete) · Fan-out TTLS: fan-out time to last step (in-deployment start() → last of the parallel step bodies to complete, i.e. when the Promise.all resolves) · STSO: step-to-step overhead (gap between consecutive step bodies) · WO: workflow overhead (whole-run time outside step bodies, in-deployment anchored) · CRTT: chunk round-trip time (per-chunk write → read latency, one clock domain: deployment → stream backend → same deployment) · CDV: chunk delay variation / delivery jitter (inter-arrival gap minus inter-write gap per seq-adjacent pair; skew-free; the row is each run's MAX positive value, so one stall moves it)}

_{Scenarios — step: one trivial no-op step, no stream; no hooks, so the run stays in turbo mode (in-process fast path) · stream: one streaming step; no hooks, so the run stays in turbo mode (in-process fast path) · hook + stream: registers a hook before one step, which exits turbo mode (dispatch path) · 1020 steps: 1020 trivial sequential steps; STSO is measured between consecutive steps in the given step ranges, and WO is the whole-run overhead outside step bodies · Promise.all(100 steps): 100 trivial no-op steps started together in a single Promise.all; Fan-out TTFS is the first of them to complete and Fan-out TTLS the last, both from the in-deployment clientStart, so their gap is the spread the runtime adds across the fan-out · paced control (100/s, 60B): the control: 300 tiny (~60B) deltas metronome-paced at 100/s — zero workload structure, so it reads the transport floor and flush cadence, and disambiguates transport-wide vs workload-specific when a replay row moves · size sweep (100/s, 160B-12KB): same pacing as the control with deltas padded in rotation across seven log-spaced sizes (~160B–12KB) — rotation decouples size from stream position, so it isolates whether chunk size causes latency · replay gateway-gpt-5.4-nano-2000t (1x): raw provider SSE cadence captured at the AI gateway boundary (gpt-5.4-nano, the most popular gateway model; per-token deltas p50 208B = the modal production chunk size), replayed exactly as measured — the typical customer's workload; its CDV is the typical customer's real delivery jitter · replay eve-gpt-5.6-sol-2000t (1x): a captured eve turn (gpt-5.6-sol, the most-used demanding eve model; ~2000 output tokens = production p50 turn length) replayed exactly as measured — eve's envelope protocol re-ships the cumulative message so sizes ramp 142B→13KB; the demanding outlier tenant's reality · replay eve-gpt-5.6-sol-2000t (2x): the same eve capture at 2x — the headroom/stress row; real fast-tier models emit the same chunk sizes at proportionally higher rate, so time compression is a faithful speed model · first chunk (pooled): every run's seq-0 RTT pooled across all stream scenarios — the first chunk precedes any workload differentiation, so pooling samples one shared stream-open path with exact percentiles}

_{Replay cadences (semantic sha256) — eve-gpt-5.6-sol-2000t eaf22f5946e7c61f3c65c7006d550df180cfabd4e706254a09f22aec0cfb420d · gateway-gpt-5.4-nano-2000t 6f24ac518b6b83ff1d0e85a5fe78230db192716d66a7fc6b2fe022752001d041}

_{🔴 marks a percentile over its target (within target is left unmarked). Targets (p75/p90/p99, ms) — TTFS 200/300/600}

_{All timestamps are deployment-side; runs are triggered in-deployment, so the CI runner and api.vercel.com sit outside every measured window. TTFS = start() → first step body (includes dispatch + any cold start); Fan-out TTFS/TTLS = first/last step completion of one Promise.all from the same anchor (the gap is the runtime’s fan-out spread); STSO/WO between step bodies; CRTT inside the workflow (excludes the api.vercel.com read path).}

_{Cold starts stay in the numbers (real bursty-workload latency, inflates P75+); Best is the warm floor.}

No backport to stable for ea782bf (AI decision).

This is a routine patch bump of the docs app's Next.js pin (16.3.3 -> 16.3.6) with the resulting lockfile dedupe, not motivated by a security vulnerability or a bug affecting stable. It is also confined to the docs app outside docs/content/, which is only a minimal placeholder on stable (the docs site is deployed from main only), so the bump has no effect there.

To override, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

ea782bf410ce31cea7d2db926e5ef10d1a2879c8

Align the remaining Next.js pins in the repo on 16.3.6, which the docs app already moved to in #4395: - `@workflow/next`'s `next` devDependency - `workbench/nextjs-turbopack` - `workbench/nextjs-webpack` - `workbench/swc-playground` The `next` peerDependency on `@workflow/next` stays `>13`; only the pinned devDependency and the app pins move.
