Steam Next Fest October 2026 Demo Go-Live Worksheet - Lock Before Oct 19

If you searched steam next fest demo go live in the week before October 19, 2026, you do not need another calendar screenshot. You need a fill-in go-live worksheet that locks six decisions before Discord invents “we will figure it out at 9:55 AM PDT”:

1. Cliff time — Next Fest opens October 19 at 10:00 AM PDT; set the demo live or opt out before that time (Steamworks October 2026)
2. Decision code — GO_LIVE, OPT_OUT, or ESCALATE (named owner + deadline)
3. Eligibility honesty — public store page + publicly playable demo + not a prologue of shipped content + release after Oct 26
4. Build pin — exact depot / build_id / branch that will be public at open
5. Crash + chat owner — who watches hour one; who answers Discord
6. Side-lane conflict — Cooking Fest overlap, livestream tab, Wrap-Up / Scream handoff — written, not vibes

This URL is that worksheet. It is not the final nine days after Press Preview (day-by-day countdown narrative). It is not the 5-night upload dress rehearsal (upload practice nights). It is not the Press Preview decide before Sep 21 (already past for this edition). Those own countdown, rehearsal, and press-shelf decisions. This URL owns the fill-in LIVE / OPT-OUT artifact for the Oct 19 open.

Why this matters now

Today is October 12, 2026 — one week from open, and Steamworks still says: on October 19, set your demo live or opt out if plans changed, before 10:00 AM PDT. The October edition runs October 19–26, 2026 (10:00 AM PDT both ends) per the October 2026 Next Fest documentation. Parent Next Fest docs still remind you that you get one Next Fest participation per title.

Teams that treat “registered” as “done” show up with a private demo, a wrong build_id, or a Cooking Fest discount fight in the same hour. The final nine days article tells you what each calendar day should protect. This worksheet makes you write the verb — LIVE or OPT-OUT — with gates outsiders can audit.

Direct answer: Fill Sections A–E before October 18 EOD your timezone (earlier if you sleep through PDT mornings). Pick GO_LIVE or OPT_OUT. Do not leave the checkbox half-true. File the receipt JSON the same day you latch the verb.

Who fills this worksheet

Time: 40–60 minutes first pass; 15 minutes to re-latch after each build promote.
Honest limit: Steam can revise partner docs — re-check Steamworks October 2026 before you quote times to a publisher. This worksheet models published October 2026 dates, not a promise Valve will text you at 9:59.

Non-repetition

Pair ops with 12 preflight checks before steamcmd setlive, Steam depot promoted playtest build label mismatch fix, and 12 free Steam wishlist analytics tools for Next Fest week after the verb is latched — not instead of it.

Official facts you must quote (not invent)

From Steam Next Fest: October 2026 and the parent Next Fest docs:

1. Fest window — October 19, 10:00 AM PDT → October 26, 10:00 AM PDT (UTC-7).
2. Open-day verb — set your demo live or opt out if plans changed, before 10:00 AM PDT on October 19.
3. Eligibility — Steamworks account in good standing; published public store page; not a prologue/chapter of already-available content; publicly playable demo by fest begin; release after Oct 26, 2026 conclusion.
4. One Next Fest — titles participate in one Next Fest; next planned edition after October is February 2027.
5. Opt-out path — return to the registration page, deselect the checkbox; future editions may still be possible if you remain unreleased and eligible.
6. No official Steam livestream (since Oct 2024 changes) — developer livestreams optional on a separate tab.
7. Wrap-Up — October 26 Wrap-Up featuring most-played demos launches the same day the fest concludes.

Pasteable diligence line:

We will GO_LIVE or OPT_OUT for Steam Next Fest October 2026 before 10:00 AM PDT on October 19. Publicly playable demo + pinned build_id + crash owner are written on the go-live worksheet receipt. We are not treating registration alone as participation.

Beginner path — 45 minutes

Prerequisites: Steamworks access to the base game App Admin / Next Fest opt-in page; you know whether the demo build is already reviewed and settable live.

1. Open October 2026 Next Fest docs and write Oct 19 10:00 AM PDT on a sticky.
2. Fill Section A (identity) and Section B (decision code).
3. Run Section C eligibility ticks — any Fail → prefer OPT_OUT or ESCALATE, not hope.
4. If GO_LIVE → fill Section D gates G1–G8.
5. If OPT_OUT → complete Steamworks deselect + February 2027 note the same day.
6. Paste Discord. Save the receipt JSON.

Common beginner mistakes:

Section A — Project identity (fill in)

Section B — Decision codes (pick exactly one)

Destination worksheet

Worked examples (patterns, not fake case studies)

Pattern Ready demo — GO_LIVE
Build reviewed, store public, demo settable public, crash owner named, no Cooking Fest discount fight. Latch GO_LIVE by Oct 18. Re-verify public install at Oct 19 09:30 PDT.

Pattern Broken save / wrong depot — OPT_OUT
Hour-one playtest still writes wrong AppData or old depot content (depot mismatch help). Opt out, fix, aim February 2027. Do not burn the one Next Fest slot.

Pattern Legal / rating blocker — ESCALATE
Partner must approve trailer permissions or age rating text. Write decide-by Oct 18 15:00 PDT. Default to OPT_OUT if silence.

Pattern Cooking Fest temptation — still GO_LIVE or OPT_OUT for Next Fest
Cooking Fest (Oct 12–19) is a different product class. Discount % math lives on the cooldown worksheet. Do not let a themed-sale argument delay the Next Fest verb.

Section C — Eligibility self-check (all must Pass for GO_LIVE)

Any Fail → you do not get to invent eligibility. Prefer OPT_OUT or fix before the cliff. The upcoming Stop opinion in backlog will attack wallpaper claims; this worksheet makes you tick the boxes first.

Section D — Go-live gates G1–G8 (GO_LIVE only)

If G3 fails at 09:40 PDT on Oct 19, you are not GO_LIVE — execute OPT_OUT if still possible, or emergency fix with the decision owner on the call.

Cross-check promote mistakes with 12 preflight checks before steamcmd setlive and depot playtest label mismatch help.

Section E — Side lanes (write so they cannot ambush open)

Hour-of runbook (October 19 morning PDT)

Do not schedule a Unity/Godot/Unreal upgrade in this window. Do not “just tweak” the depot after 09:00 unless G3 failed and the owner ordered a single pin flip.

OPT_OUT path (same-day discipline)

1. Open https://partner.steamgames.com/optin/sale/nextfest_october_2026/<AppID> (per Steamworks).
2. Deselect the festival checkbox; confirm removal.
3. Tell creators / Discord the truth in one sentence.
4. Write a February 2027 prep note (registration windows will be published later — do not invent dates).
5. File receipt with decision: OPT_OUT.
6. Do not leave a registered private demo hoping nobody notices.

CapEx four-liner (companies)

1. Risk of skip: A private or broken demo at Next Fest open burns the one Next Fest slot and wishlist trust.
2. Destination cost: One worksheet evening + open-hour staffing — cheaper than a week of apology posts.
3. Avoided cost: Mid-open depot archaeology and Cooking Fest discount fights.
4. Decision: GO_LIVE / OPT_OUT / ESCALATE — owner + PDT clock above.

Discord paste (creators)

Steam Next Fest Oct 2026 — go-live worksheet latched.
Verb: [GO_LIVE | OPT_OUT] before 10:00 AM PDT Oct 19.
Build_id/branch: [pin]. Crash owner: [name]. Chat: [name].
Cooking Fest: [skip|honest join]. Livestream: [STREAM|NO_STREAM].
Receipt in #releases. No engine upgrades this morning.

Developer path — promote without folklore

1. Tag pre-nextfest-golive-YYYYMMDD on the demo branch.
2. Record Steamworks build_id in Section A — no “latest.”
3. Run non-team install from a clean Steam account (G3).
4. If Input metadata rejected uploads earlier, use Next Fest demo upload Steam Input fix patterns before open morning.
5. Freeze Hub / editor upgrades (mid-fest pin).
6. After open, measure wishlists with the analytics listicle — do not start measurement debates before the verb.

FAQ

When must the demo be live for Steam Next Fest October 2026?

Steamworks says set your demo live or opt out before 10:00 AM PDT on October 19, 2026, when the fest begins. Confirm on the October 2026 documentation.

Is this the same as the final nine days article?

No. The final nine days page is a day-by-day countdown. This page is the fill-in LIVE / OPT-OUT worksheet with eligibility ticks and gates.

What if Press Preview already started and we skipped it?

Focus on the public Oct 19 verb. Press Preview (Oct 8) is a different shelf. Do not invent a late press path on Oct 18.

Can we join Next Fest without a playable demo?

No. Eligibility requires a publicly playable demo by the time the festival begins. Wallpaper store pages fail E4.

How do we opt out?

Use the Steamworks registration page for your AppID and deselect the festival checkbox (see Steamworks FAQ on the October page). Then write a February 2027 note.

Does Cooking Fest block Next Fest?

No — they are different programs that overlap on the calendar. Write Section E so discount fights do not delay the demo verb.

Should we livestream?

Optional. There is no official Steam Next Fest livestream stage for recent editions. Pick STREAM or NO_STREAM explicitly.

What happens October 26?

Fest concludes at 10:00 AM PDT; Wrap-Up launches. Plan metrics handoff. Scream V honesty is a separate URL if you join horror themed sales.

What primary keyword does this page target?

steam next fest demo go live — fill-in worksheet for the Oct 19 cliff.

Where do wishlist analytics fit?

After the verb is latched. Use the wishlist analytics listicle during the fest week — not as a substitute for GO_LIVE gates.

Conclusion

October 19 does not negotiate. Fill the worksheet. Latch GO_LIVE or OPT_OUT before 10:00 AM PDT. Pin the build. Name the humans. Leave Cooking Fest and capsule debates in Section E where they cannot ambush the open hour.

File the receipt. Paste Discord. Protect the one Next Fest slot you get.
