docs: drop shipped and superseded design pages, fix stale labels and dangling citations - #479
A pass over the open docs (design/, future/, review/, TODO.md) against the code. This PR covers the factual fixes and the pages whose knowledge already lives elsewhere. Folding and shrinking the larger pages comes in a separate PR.
Fix 2 is in the apply_barrier.go file comment (#456); Fix 1 was rejected
facts/kubernetes-apf-and-inflight-tuning.md
it was wrong: it recommended distinguisherMethod: ByResource, which Kubernetes rejects (only ByUser and ByNamespace exist). TODO.md asks for a measured replacement
Every incoming link is repointed. Pages under finished/ keep the name with "(removed)", the convention already used there.
Fixed
Go comments that cited missing sections:
four cited kustomize-support-boundary.md §7, which does not exist; removed.
Updated the design index, task lists, and related references to reflect current documentation status.
Revised guidance on push cooldowns and supported repository layouts, including clarifications about read-only Helm values files and planned Git-path handling.
Removed several design, planning, and review documents, including guides on Git server selection, event processing, branch ownership, and Kubernetes API Priority and Fairness.
Updated related documentation links and descriptions; no runtime behavior changes are noted.
…dangling citations
Delete nine pages whose knowledge already lives in code, another doc or git history:
vocabulary-cleanup, gitbranch-and-kubeprovider-plan, reconcile-triggering,
watches-labels-simplification, event-pipeline-overview, one-writer-per-branch-plan,
e2e-git-server-choice, future/config-surface-for-a-structured-repository and
review/20261026-apply-window-late-events. Every incoming link and Go comment is repointed;
the one-writer page's open items (first-proven branch claim, alias detection, delivery rate)
move to TODO.md.
Delete facts/kubernetes-apf-and-inflight-tuning.md: it recommended distinguisherMethod
ByResource, which Kubernetes does not accept (ByUser and ByNamespace only). A TODO item
asks for a measured replacement.
Remove four Go comments citing kustomize-support-boundary.md §7, which does not exist, and
name the rbac.md section two comments cited as §5.
Rewrite push-cooldown.md for concurrent commit windows: same-target authors on disjoint files
no longer close each other's windows, so the cooldown now batches early closes (another
GitTarget, overlapping or unproven footprints, buffer limit, idleTimeout 0s) and side-by-side
windows closing together.
Correct support-contract.md: overlays are accepted by scan-repo, referenced values files are
read-only context, and ImageUpdateAutomation and .argocd-source paths are planned rather
than refused. Fix INDEX.md labels (concurrent windows built, parentBranch on GitBranch,
open-asks-priority stale, source-scope row) and list the pages it was missing.
Add a TODO item for go-git v6.0.0-beta.1's RemoteRefs.Unborn, which may unblock learning
an empty repository's default branch and let the workaround code go.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
This pull request updates documentation and comments. It revises the push-cooldown description, updates the index and TODO list, removes several design documents, and changes references to those documents. No runtime behavior changes are described.
Changes: Documentation and design records
Layer / File(s)
Summary
Update the index and backlog docs/INDEX.md, docs/TODO.md
The index revises document statuses and deferred work. The TODO list adds work on branch discovery and claims, repository aliases, push-delivery rates, and API Priority and Fairness documentation.
The documentation describes cooldown behavior with concurrent author windows, early closures, and commit batching. It updates the conditions, examples, measurements, and recommendation.
The pull request removes several design, facts, proposal, and review documents. Related documentation and comments update or remove references to them.
The support contract updates layout and Helm values-file classifications, planned path handling, and Git write preflight status. Related code comments remove references to the support-boundary design document.
ConfigButler/gitops-reverser#462: Introduced the concurrent-author-window design and recorded documentation cleanup that this pull request continues.
ConfigButler/gitops-reverser#478: Implemented concurrent per-author commit windows, which the revised cooldown documentation describes.
Merge Risk: Low · up to c1c13
This is a documentation-only change. A few statements about push cooldown and the support contract are slightly inaccurate or too broad and should be corrected, but nothing affects runtime behavior.

- Line 95: Update the Helm values-file row in the support contract to qualify
its read-only guarantee: non-KRM values files remain retained and unwritten,
while files whose first document has nonempty apiVersion and kind follow normal
manifest rules and may be written or removed. Keep the existing ValuesFile
projection reference and scope unchanged.
Review comments at @docs/INDEX.md:
- Line 141: Update the restart-recovery wording in the branch-worker event-model
entry in the index to state that pending writes and save outcomes are retained
only for the worker’s lifetime and may be lost after a crash; make clear that
restart recovery is not implemented.
- Line 159: Update the timer-spacing claim in the push-cooldown entry of the
index to qualify that a window closed by its own timer is spaced beyond the
fixed cooldown only when idleTimeout is at least the cooldown; preserve the
existing discussion of early closures and closely timed windows.
Review comments at @docs/misconceptions.md:
- Line 179: Update the cooldown explanation around maybeSchedulePush to say it
can batch commits only while active; clarify that the first commit may push
immediately when no push has occurred, and apply flushes or pending
CommitRequests can bypass the cooldown and produce separate pushes.
Review comments at @docs/TODO.md:
- Around line 251-253: Update the API Priority and Fairness TODO to distinguish
inbound watch-request classification from outbound audit webhook delivery:

that aliases normalizing to different keys may still refer to the same remote

Account for a delayed successful retry.
The cooldown starts at the successful push, not at the previous commit. For example, if a push fails at t=5 and succeeds on retry at t=15, a new window opened at t=11 closes at t=16 and waits until t=20.

Allow for multiple commits in one push.
Without the cooldown, one event can still close several windows before the worker schedules a push. For example, a write to another GitTarget closes all existing windows in admitWrite; endWake then advances their writes together. Describe option B as pushing after each wake with pending commits, rather than after every commit. (raw.githubusercontent.com)

Two authors on one target, editing different files, no longer close each other's windows. The cooldown now batches early closes (anotherGitTargeton the branch, overlapping or unproven footprints, the buffer limit,idleTimeout: 0s) and windows open side by side that close within seconds of each other.
