Conversation
…ision layering GOVERNANCE.md defined roles, nomination, and voting thresholds, but left three questions unanswered that a project needs settled before they are asked in anger. Dispute resolution: the document said Project Leaders break ties without saying who may call a vote, whether any role holds a veto, what happens to a contested nomination, or whether a maintainer votes on their own removal. Those rules now sit in one place and reuse the existing eligible-voter mechanics rather than introducing a second, competing one. Deprecation and end-of-life: there was no policy for retiring a provider, engine, endpoint, label key, config field, or Helm value, all of which downstream projects and operators depend on. The policy states what a public surface is, what makes a change breaking, a notice period of two minor releases and at least six months, announcement through a CHANGELOG Deprecated heading, and removal in a major release, with narrow exceptions for a security fix and for a provider whose upstream API is withdrawn by its owner. Project-level end-of-life stays reserved to NVIDIA as an IP decision, matching the existing clause. Decision layering: merging a dependency bump and changing the label contract that KAI Scheduler, NVSentinel, and Kueue read were governed by the same undifferentiated process. They are now separated into operational and strategic layers with the deciding party named for each. Topograph does not charter a separate steering committee; the maintainers listed in MAINTAINERS.md acting collectively are the steering group, which is how the project already works with two active maintainers.

The deprecation policy said removal "lands in a major release", read off semantic versioning rather than off this project's release history. The history says otherwise. Release 0.5.0 was a minor release and it removed the node-data-broker init container along with the entire node-data-broker.initc Helm values block, shipping a migration table for the renamed keys. v1.0.0 removed the --refresh-interval flag and nodeDataBroker.refreshInterval value that 0.5.0 had introduced one release earlier. RELEASE.md names semantic versioning once, as something the release person should understand, and says nothing about compatibility, breaking changes, or a major bump. The word "deprecat" does not appear in CHANGELOG.md at all, so no removal in the project's history has ever carried advance notice. A rule the maintainers would have to break the next time they retire a Helm value is not a policy, so the version bump goes back to being their call at release time, weighed against how many deployments the removal breaks. What the policy still binds is the part that protects users: the notice period, the CHANGELOG announcement under a Deprecated heading, a documented replacement available on the day of the announcement, and a migration note in the shape of the tables already in the 0.5.0 and v1.0.0 entries. Removal stays out of patch releases, which carry fixes only. The security and upstream-withdrawal exceptions and the carve-out for a surface that never appeared in a tagged release are unchanged.

Greptile SummaryThis documentation-only PR expands Topograph's governance policy:
Confidence Score: 5/5The documentation change appears safe to merge, with the latest revision resolving the prior conflict between referral outcomes and governance-amendment authority. All previous findings were manually resolved, and the current text addresses them: ordinary non-IP referrals now have a defined failure outcome, valid InfiniBand provider identifiers are used, and governance amendments are explicitly routed to the separate Governance changes rule.

Define the authority for dependency updates.
Line 150 classifies dependency updates as operational, but Line 180 classifies changes to dependencies as significant. As written, maintainers cannot determine whether a dependency update requires a proposal and vote. Limit operational updates to non-breaking changes, or define an explicit precedence rule.

Apply the correct seconding threshold to each nomination type.
“Both its seconds” conflicts with the nomination rules: reviewer nominations need one second, maintainer nominations need two, and area-bootstrap nominations need three from existing maintainers. State that a contested nomination retains the applicable threshold before the majority vote.

Keep the eligible-voter denominator fixed.
Line 193 fixes the eligible-voter list when voting opens, but Line 229 removes the subject before counting. This can change a two-thirds threshold and turn a failed removal vote into a passing vote. Exclude conflicted voters when the list is created, or define a fixed denominator and abstention rule. Also state how a conflicted Project Leader participates in the tie-break.

Two fixes from review of the dispute-resolution and deprecation sections. The referral of last resort named NVIDIA as the escalation point but only defined what NVIDIA decides for the reserved IP matters, which are license changes, project end-of-life, and transfer of the project. A non-IP deadlock referred under that clause had no stated terminus, so the process meant to break a stall could itself stall. The clause now splits the two cases: on the reserved matters NVIDIA decides and the decision binds; on everything the maintainer group holds, NVIDIA answers with a recommendation, and if that does not settle the question within 10 business days the proposal fails and the current behavior stands, reopenable on the same terms as a proposal that failed on a tie. That keeps roadmap, architecture, contribution model, and release cadence with the maintainers, as stated under Significant changes, while still guaranteeing an outcome. It also needs no body beyond the maintainers listed in MAINTAINERS.md. The public-surface table named a provider `infiniband`, which is not a registered name. The registry wires infiniband.NamedLoaderBM and infiniband.NamedLoaderK8S, whose NAME constants are `infiniband-bm` and `infiniband-k8s`. The row now lists names taken from the live registry, and adds `oci-imds`, which the old "and the simulation variants" tail did not cover because it is not a simulation variant.

…rule The referral of last resort said that on every matter outside NVIDIA's reserved IP authority a referral produces a recommendation, and that an unsettled proposal fails after 10 business days. A proposal to change this document fell inside that sentence, so it collided with the Governance changes section, which says NVIDIA can change the document without a vote when the maintainers do not reach a two-thirds supermajority. A disputed amendment therefore had two rules pointing at opposite outcomes, failure or unilateral adoption. The referral now carves that case out and sends the reader to Governance changes, which is the rule the project already adopted and which the referral has no business overturning. The 10-business-day window is unchanged for the categories it legitimately covers. Checked the other categories a referral can sweep for the same double coverage. A tied vote on a significant or architectural change, a contested nomination, or a PR appeal reaches the same outcome under Ties as under the referral, and the referral already cites Ties for its terms. Removal of a maintainer for cause has no competing fallback clause. Only the document change was double covered. Signed-off-by: Carlos Eduardo Arango Gutierrez <eduardoa@nvidia.com>

Fix the reserved-matter reference.
Line 233 lists three matters reserved to NVIDIA: license changes, project end-of-life, and project transfer. Line 237 says “those two,” so one matter can be excluded from the binding-authority rule. Refer to “the matters reserved to NVIDIA above” instead.

Description
Adds three things GOVERNANCE.md did not cover: how a deadlocked decision is resolved, how a
public surface is deprecated and removed, and where the line sits between decisions a
maintainer makes alone and decisions the group makes together.
Part of the OSS Health Scorecard work tracked in #513.
What
and how a tie is broken. The document previously described roles without saying what happens
when they disagree.
pkg/registry, the Helmprovider.nameandengine.namevalues, the fabric andaccelerator label keys consumed by KAI Scheduler, NVSentinel and Kueue, and the API
endpoints), the notice period, and the announcement mechanism.
maintainer escalates something that looks operational but is not.
The removal rule matches what this project actually does
An earlier draft of this PR said removals land in a major release, reasoning from semantic
versioning. That was wrong on the evidence:
RELEASE.mdpromises nothing about compatibility. Semver appears once, in the releaseengineer's prerequisites, as something to understand. There is no statement that a breaking
change waits for a major bump.
0.5.0removed thenode-data-broker init container and the entire
initcvalues block, with a migration table.v1.0.0removed the--refresh-intervalflag and its Helm value one release after0.5.0introduced them, and describes its own security-context change as breaking.
So the rule now says removal happens in a minor or major release once the notice period has
elapsed, never in a patch, with the version bump chosen at release time against how many
deployments the removal breaks. The binding parts remain: the notice period, a
### DeprecatedCHANGELOG announcement, a documented replacement available on the day of the announcement, and
a migration note in the shape of the ones already in the changelog.
Two things that need explicit maintainer agreement, not a nod
CHANGELOG.mdcontains no
### Deprecatedsection and no deprecation has ever been announced. Everythingelse in this PR describes what already happens; this one asks you to start doing something.
That follows from the existing rule rather than from this PR, but it is now written down
where someone will notice it.
Scorecard effect: none
Measured at exactly +0.00. The three governance bonus signals already passed on
main, andthis dimension is already at 4.00/4. Included because a project with downstream consumers
should have a written deprecation policy, not because it scores.
