The install selectors labeled nightly chips with the Dynamo dev-wheel version and stamped every nightly entry with MAIN_TOT, so both quickstarts claimed the Aug 3 and older builds shipped a tip-of-main backend version they never carried. Nightly chips are now the last three versions of each backend, each resolving to the newest nightly wheel that shipped it. NIGHTLY_BACKEND_BUILDS holds that mapping, derived from container/context.yaml history on main crossed with the wheels published to pypi.nvidia.com, joined at the nightly-ci cron instant (08:00 UTC). Only the tip-of-main chip carries a container command, since nightly containers publish rolling latest tags with no date-pinned equivalent. TensorRT-LLM keeps a single chip because it publishes no nightly wheel. NIGHTLY_BUILDS had not been refreshed since Aug 4 and now carries the three most recent nightlies.

…ing it The nightly dimension of the install selectors was a literal in releases.data.ts, so it only refreshed when someone remembered. It had not been touched since Aug 4 and its tip-of-main rows had to agree with MAIN_TOT, which an unattended bot rewrites every one to two weeks. gen_nightly_selector.py rebuilds that data from authoritative sources on every docs publish and on a daily cron. The dated YYYYMMDD-<sha> tags on the public NGC nightly repos name the commit each build came from, so backend versions are read from container/context.yaml at that exact commit rather than inferred from build times. Wheel pins are confirmed against the pypi.nvidia.com index, so a skipped or garbage-collected night drops its wheel command instead of offering a dead install line. The generated module is gitignored and rebuilt in CI, restoring the shape that build_install_selector.py had before it was dropped in the tab-navigation restructure. The two .gitignore entries it left behind pointed at the pre-restructure paths, which is how the generated file became a tracked one. Both selectors now offer every backend version an immutable container tag, so TensorRT-LLM is no longer limited to a single chip. The Kubernetes quickstart keeps only the rolling entry, since its emitted variables do not pin worker images. Unreachable upstreams degrade to a valid empty module rather than failing the docs publish. Signed-off-by: Anant Sharma <anants@nvidia.com>
Pushes to main already republish the docs whenever the docs filter matches, and it matched on 43 of the last 46 days with commits, longest gap three days. A daily trigger would almost always fire on a day that had already published several times. The chip set cannot go stale between publishes either: it is keyed on backend version, and a backend bump touches MAIN_TOT in releases.data.ts, which is under docs/ and triggers a publish in the same push. Only the newest chip's wheel pin and date lag within a gap, and its container command is the rolling latest tag, so it stays correct regardless. Signed-off-by: Anant Sharma <anants@nvidia.com>
The selector emitted dynamo-planner:nightly, which NGC does not serve; that repository carries only stable semver tags. Nightly component images live in their own repositories, so the nightly planner is dynamo-planner-nightly, which publishes both a rolling latest tag and dated YYYYMMDD-<sha> tags matching the runtime nightlies commit for commit. The Nightly Releases page listed dynamo-frontend, kubernetes-operator, dynamo-planner, and snapshot-agent as things nightly does not publish. All four have current nightly repositories, so the page now lists them as published and keeps only the claims that still hold. Signed-off-by: Anant Sharma <anants@nvidia.com>

Handle nightly builds with no wheel instead of showing "Nightly undefined", disable the Kubernetes selector's output instead of silently falling back to the current stable tag when no entry matches, fix inconsistent prerelease spelling and the SPDX year range, close urlopen() responses with context managers, and narrow the NGC/PyPI exception handling so malformed responses fail generation instead of silently dropping a backend.

Update NIGHTLY_BUILDS to the latest published ai-dynamo, ai-dynamo-runtime, and kvbm nightlies, regenerate the synced release-artifacts.mdx and releases-machine-readable.mdx tables, and bump the example wheel version in nightly-releases.md. Signed-off-by: Anant Sharma <anants@nvidia.com>
The latest row's wheel used to require a night that shared a commit with the newest NGC container tag, so it lagged whenever the wheel and container nightly CI jobs fell out of step. Pick the newest published PyPI wheel directly for that row; pinned rows still match the container tag's exact commit for reproducibility. Signed-off-by: Anant Sharma <anants@nvidia.com>

Review of head 66b9e58: 1 must-fix, 5 consider. The generator's external assumptions were verified end to end with live probes of NGC and pypi.nvidia.com, and the publish plumbing is sound; the one blocking item is a leftover false claim on a line this PR rewrites.
Must-fix
docs/fern/pages/reference/general/nightly-releases.md:33- "Nightly deliberately does not publish EFA image variants" is false: all three*-runtime-nightlyNGC repos carry-efadated tags (21 on vllm-runtime-nightly, through20260826-27f09d5-efapluslatest-efa), andnightly-ci.yml:333lists runtime EFA variants among its nightly images. Suggested wording: "Nightly EFA variants publish as-efasuffixed tags (latest-efa,YYYYMMDD-<shortsha>-efa). Nightly does not publish Helm charts or Rust crates."
Consider
docs/fern/scripts/gen_nightly_selector.py:370- a total NGC outage at publish time ships an empty module silently: per-backend HTTP failures skip gracefully (good), but when every backend skips,mainstill returns 0 and the sync steprm -rfs the last-known-good copy, so the live selectors lose all nightly rows until the next publish. Return nonzero whenrowsis empty so a total outage holds the publish.docs/fern/components/InstallSelector.tsx:163- pinned TRT-LLM rows carrydynamobut no wheel command, so the card renders a wheel-flavored title and eyebrow while offering only a container command; key both onentry?.commands.wheel.- Local
fern docs devfrom a fresh clone now hits an unresolved./nightly-selector-data.generatedimport (gitignored, CI-generated, needs network), and pre-merge cannot catch it; document running the generator first in the local-preview section, or add an offline flag that writes an empty module. InstallSelector.tsx:213- with an empty nightly array the Nightly chip stays clickable but the version row silently vanishes; the Kubernetes selector got an explicit "Not currently available" state in this PR, this one did not (and the generator's warning text says the channel "will hide", which is not what happens). Mirror the K8s message.nightly-releases.md:46- "emits them for each backend version" overstates: the latest row deliberately emits the rolling:latesttag; only pinned rows emit immutable tags. "emits them for pinned backend versions."
Verified sound
Live NGC probes: the anonymous token flow works as coded, all three nightly repos exist with dated YYYYMMDD-<7hex> tags, pagination handles the no-Link-header case, and the EFA/signature tags are correctly excluded by the regex. Live PyPI probes: the refreshed ledger rows are accurate against both indexes and byte-match the generated tables. The read-at-commit assumption held at three real tagged commits with real version variance. Publish plumbing verified: gitignore paths, docs-website sync, the shallow-clone guard failing closed, and the component-image name fixes all check out. All repo gates green, docs linter proven on the three changed pages with a known-positive probe.

The nightly rows of both install selectors labeled chips with the Dynamo dev-wheel version and stamped every nightly with MAIN_TOT, so they claimed builds shipped backend versions those builds never carried. The underlying data was a hand-maintained literal that hadn't been refreshed since Aug 4. Nightly chips are now the last three versions of each backend, each resolving to the newest nightly that shipped it, generated at docs-publish time instead of transcribed.
