feat(api)!: give every concept one name, and make the API follow it - #397

Conversation
…the API obey it An audit of all six CRDs (status objects, printer columns, condition reasons, spec fields, flags and chart values) found the surface is named well wherever the naming rules were written down first, and named inconsistently everywhere the rules arrived late. The rules for prose and for flags already existed; the rules for concepts and API names did not. docs/definitions.md is the third rulebook. It fixes the ambiguity the other mistakes grew out of (the word "cluster" with no side, "namespace" with no direction), names one word per concept across the read side, the write side, attribution and status, and states nine rules that decide a kind, field, condition type, reason, enum value or printer column. It binds. docs/design/vocabulary-cleanup.md is the plan: thirteen condition reasons, seven printer columns, two status field renames and one spec block, in a single breaking release because a reason is a string no schema can deprecate. Each schema item is checked against the question docs/facts/crd-upgrade-strategies.md says decides the cost, and only one prunes fail-open. It also records the four audit findings the existing rulebooks already settled, so they are not re-raised: the insecure flag suffix-vs-prefix split, bare-noun booleans, --redis-addr with a valkey default, and the lowercase sops enum, which matches Flux's own spelling and is correct as it stands.

…o we borrow from Asking whether the PascalCase enums should be lowercase like much of Flux's surface was the right question for a breaking release, and the answer is no. Measured, not recalled. Kubernetes core/v1 is PascalCase for every mode it invents, uppercase for acronyms, and lowercase only where a value names something outside the API: linux and windows are operating systems, noexec and nosuid are Linux mount flags, cpu and pods are resource names. Flux approximates that and does not hold it: it lowercases modes it invented itself (extract;copy, none;client;server, enabled;warn;disabled, poller;legacy), one enum mixes casing internally (head;HEAD;Tag;TagAndHEAD), and HelmRelease's deletionPropagation is background;foreground;orphan where the metav1.DeletionPropagation values it names are Background, Foreground and Orphan. Our enums already match the right model (Never, Always and Ignore are literal core/v1 values; ConfigMap;Secret matches Flux's own Secret;ConfigMap), so nothing changes. Rule 7 now says which model and why, and adds the acronym case. What the question did produce is a table at the top of definitions.md naming what we borrow from Flux (condition reasons, readiness shape, flag conventions, verbatim mirrored fields) and what we take from core/v1 instead (enum value shape, field and timestamp shape), so the split is decided once rather than per field.

Codecov Report❌ Patch coverage is
📢 Thoughts on this report? Let us know! |
… spec Two changes, both prompted by not being able to tell which types the renames sit in. The plan gains a worked before-and-after per kind: the real kubectl header rows (taken from config/crd/bases, so the "before" is exact) and the status snippets each rename lands in. It makes three things visible that a table of strings hid. A rule pointed at a GitProvider that does not exist reads reason: GitRepoConfigNotFound, naming a kind the API has not had for a long time. GitTarget prints PROVIDERREADY next to CLUSTERPROVIDERREADY, which reads as a general and a special case of one thing rather than two peers. And ResourcesResolved, the condition that answers whether a rule matched anything the cluster serves, has no column on either rule kind. The second change is a correction. docs/spec/status-conditions-guide.md already owns the condition and reason contract, including the rule that a reason restating its condition type answers nothing, and spec/ binds. definitions.md had restated it in three places, which is the duplication the page exists to end. It now defers: rule 5 points at the guide, rule 6 keeps only the two clauses the guide does not make (one axis per condition type, and a reason names a cause rather than a negated type), and rule 8 credits the guide for the status.streams.summary exception rather than re-granting it. That also sharpens the plan. The eight Succeeded rows are not a proposal about taste: they are a binding spec the code does not currently obey, and the table now cites the guide for them instead of citing this change's own rules. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…r a commit hash Two decisions, both narrowing the change rather than widening it. GitTarget's ProviderReady and ClusterProviderReady columns are removed instead of renamed. The earlier draft renamed the first to GitProviderReady so it would stop reading as the general case of the second; shortening the other way (GitReady, ClusterReady) does not work, because GitReady sits beside GitPathAccepted where Git means the repository, and ClusterReady sits beside SourceReachable which is about the cluster itself. Provider is the token that separates the config object from the thing it names. That left the better question: both columns only project another object's Ready, and Ready's own reason already carries GitProviderNotReady or ClusterProviderNotReady, since those are the first two progressing contributors. So rule 8 now excludes a dependency-readiness projection from getting a column at all, the asymmetry goes away without a rename, and GitTarget drops from twenty columns to eighteen. Validated and EncryptionConfigured are no longer added either. The same rule condemns the existing GitTargetReady column on both rule kinds, which is recorded as a consequence to accept or reject rather than done quietly. Rule 8 also stops phrasing the abbreviation test positionally. It is not "drop a leading qualifier" but "what remains must still name the same subject and must not be readable as another column's subject", which admits SourceReachable and rejects GitReady without appealing to length. CommitRequest.status.sha, GitTarget.status.remote.revision and status.placement.resolvedAtRevision all hold a bare forty-character commit hash, verified at each of the three places they are written. Neither word is right. Flux documents Artifact.Revision as a polymorphic identifier that may be a tag or a chart version, and its Git form is composite; it documents GitRepository.spec.ref.commit as a commit SHA; and it has no sha field anywhere. So all three become commit, the CommitRequest column becomes COMMIT, and revision stays reserved for a composite identifier if one is ever needed.

…ything around There is no known production install, so nothing is kept for compatibility: no retain-and-refuse release, no conversion, no alias left behind for an old spelling. The release version carries the break and UPGRADING.md carries the warning. That is what v1alpha3 is for. The API conventions allow an alpha version to change incompatibly without a new version, which is the entire content of the alpha signal, so these renames land in v1alpha3 rather than opening a v1alpha4. Opening one would be the conservative move and would cost either a conversion webhook or an unreadable set of stored objects, for a guarantee nobody asked for. The four calls that were open are settled in the page: the per-cluster client throttles move with a one-shot delete, Message goes on all six kinds, the True-state reasons collapse to Succeeded, and the GitTargetReady column on the two rule kinds is dropped along with the two on GitTarget. Also records something that would otherwise surprise someone after the fact: a renamed reason is a metrics label change too, because resource_condition carries reason, so a dashboard selecting reason="GitPathAccepted" goes empty rather than erroring. That belongs in the upgrade entry beside the field renames. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
A WatchRule or ClusterWatchRule pointing at a missing GitProvider reported GitRepoConfigNotFound, naming a kind renamed long ago. The reason is GitProviderNotFound. The two GitRepoConfigNotReady constants were declared and never set, and are gone. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Six conditions answered "why are you True?" with their own name: GitPathAccepted, RenderMatchesLive, GitProviderReady, ClusterProviderReady, Pushed and Validated. Each now reports the shared Succeeded, which spec/status-conditions-guide.md already requires. InCluster stays as the second Validated=True reason, because it says something Succeeded cannot. ResourcesResolved=True is Succeeded too, and its False reason is ResourcesNotServed, which names the cause instead of inverting the type. Stalled becomes Flux's Failed and Suspended aliases Flux's own constant. Reconciling and Checking were never set outside tests and are gone. The data plane's healthy GitPathAccepted and RenderMatchesLive payloads carry the same Succeeded, so the controller never writes the old string. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Five compatibility aliases kept the StreamsReady spelling, and a reason named Ready, readable in the tree while nothing in production used them: ConditionTypeStreamsReady, GitTargetConditionStreamsReady, GitTargetStreamsReadyReasonNotReady, GitTargetReasonReady and GitTargetReasonConflict. The tests that used them now name the constants they stood for. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
GitTarget's ProviderReady and ClusterProviderReady columns, and the GitTargetReady column on WatchRule and ClusterWatchRule, only projected another object's Ready. Ready's own reason already names that dependency when it is the cause, and the detail lives on the other object. The conditions are still set and still aggregated into Ready; only the columns are gone. GitTarget's wide output drops from twenty columns to eighteen. BREAKING CHANGE: kubectl get -o wide no longer prints PROVIDERREADY, CLUSTERPROVIDERREADY (GitTarget) or GITTARGETREADY (WatchRule, ClusterWatchRule). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A column holding Ready's message is Message, not Status, on every kind, and it sits second to last at priority=1; WatchRule, ClusterWatchRule and CommitRequest gain it. ClusterProvider's Facts column is FactsReceived, which leads back to the AuditFactsReceived condition. The rule kinds' Target column is GitTarget, matching CommitRequest, and both gain a wide ResourcesResolved column. CommitRequest's SHA column is Commit. BREAKING CHANGE: kubectl get headers STATUS, FACTS, TARGET and SHA are MESSAGE, FACTSRECEIVED, GITTARGET and COMMIT. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A bare commit hash is called commit everywhere in the API: CommitRequest's status.sha is status.commit, and GitTarget's status.remote.revision and status.placement.resolvedAtRevision are status.remote.commit and status.placement.resolvedAtCommit. The CommitRequest Commit column reads the new field. Inside internal/git, RemoteObservation and LayoutReport follow the API. GitTarget's status.retention.lastChangedTime is lastChangedAt, the one timestamp suffix, and status.retention.mode carries the same enum as spec.prune.mode. GitProvider's status.branches[].gitTargets is gitTargetCount, a quantity rather than a bare plural. GitTargetStreamsStatus and WatchRuleStreamsStatus were the same block, and are one StreamsStatus; GitTarget gains the optional pendingSample the rule kinds already reported. BREAKING CHANGE: status.sha, status.remote.revision, status.placement.resolvedAtRevision, status.retention.lastChangedTime and status.branches[].gitTargets are status.commit, status.remote.commit, status.placement.resolvedAtCommit, status.retention.lastChangedAt and status.branches[].gitTargetCount. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…s word order ClusterProvider's spec.qps and spec.burst are spec.client.qps and spec.client.burst: two facts about one subject get a block. The old spelling is gone rather than retained, so a manifest still carrying it is pruned on apply and the provider falls back to the operator-wide --source-cluster-qps and --source-cluster-burst. --allow-insecure-git-http is --insecure-allow-git-http, the loud prefix config-flag-conventions.md reserves for a dev-only escape hatch and the spelling of Flux's --insecure-allow-http. The chart value follows as controllerManager.insecureAllowGitHTTP, and controllerManager.gitRefreshInterval moves to git.refreshInterval. BREAKING CHANGE: ClusterProvider spec.qps/spec.burst are spec.client.qps/spec.client.burst, and an old manifest silently loses its throttle. The flag --allow-insecure-git-http and the chart values controllerManager.allowInsecureGitHTTP and controllerManager.gitRefreshInterval are renamed. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
UPGRADING.md gains one entry for the release: the reason, status field, printer column, spec block, flag and chart value renames, with a command to find ClusterProviders still setting spec.qps or spec.burst before upgrading, since that is the one rename that fails open. It also names the metrics consequence precisely. resource_condition carries only the trio's reason, so the True-state collapse changes no series; GitRepoConfigNotFound, UnresolvedResources and Stalled are the three renamed reasons a dashboard can have been selecting. The plan said GitPathAccepted, which never reached the metric, and is corrected. Every reference page that named a retired field, column, flag or chart value now names its replacement, and vocabulary-cleanup.md is built. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The spec.client move is a name that changes what a cluster sees when an old manifest's throttle is pruned, so neither the plan nor the upgrade entry claims nothing behaves differently. The plan's reason count and the index's open-page count now match their tables. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
ResourcesNotServed claimed a selector had matched nothing the cluster serves, but resolution never reports that as False: a selector with no match resolves True, watching zero types. False means only that the source cluster's discovery catalog is not ready yet, so the reason is CatalogNotReady. Behavior is unchanged. BREAKING CHANGE: ResourcesResolved=False on WatchRule and ClusterWatchRule reports CatalogNotReady. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
FinalizeResult.SHA carries the value CommitRequest.status.commit holds, so it is Commit too, and the two log lines that printed a commit hash under "sha" print it under "commit". Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…hed CommitRequests The upgrade guide and the plan name CatalogNotReady, and say that a finished CommitRequest is never reconciled again and so keeps an empty status.commit; the commit is in Git. definitions.md says status.streams counts by type, not by cell: one resource in three namespaces is one entry. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…op the source-cluster flags spec.qps and spec.burst were pruned, so a manifest still setting them applied cleanly and dropped a deliberate throttle without a word. They now stay in the schema, never read, and a CEL rule refuses them by name. A provider already storing them passes by ratcheting until its spec is next edited, so UPGRADING.md still asks for the inventory first. --source-cluster-qps and --source-cluster-burst are removed. The chart never set them, and spec.client is the per-cluster knob; their defaults, 20 and 30, are built in. Also corrects the configuration guide (gitTargetCount, the commitrequest wide columns), the closeDelaySeconds comments #388 left behind, and the design doc's "every item is a name" claim.

…get, not just Ready The #397 fix retried the direct reconcile until the rule's Ready was False/Progressing, but with no streams in envtest Ready is False/Progressing either way, so the wait could pass on its first try while the reconciler's cached read of the GitTarget still had no conditions, leaving GitTargetReady=Unknown. It recurred in CI on #413. The wait now also requires GitTargetReady False/Progressing, the condition the test asserts. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

…materializer (#413) * docs(design): plan the branch worker's write path as a log with one materializer Gaps 3 to 5 of the GitTarget state of affairs are planned as one refactor: a log of decided writes, one materializer for the checkout, and one retry deadline. A failed rebuild then cannot drop a window, a publication failure has one state to project, and Git deadlines wrap two call sites. The page records the steps, the size estimate, and the settled decisions (resyncs stay in the log; a partly failed write is cleaned locally). Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * refactor(git): one materializer for the branch worker's checkout The checkout is the projection of the retained writes: the remote tip they were planned on plus one commit each. Three flags guessed whether it still was (worktreeDirty, replayRequired, and the hasPendingCommits parameter), six recoverRetainedWrites call sites consulted them, and four functions rebuilt the projection in slightly different ways. checkoutApplied now counts the retained writes the checkout holds. Unknown is a dirty worktree, which only a reset clears and a push never does; a reset sets it to zero, so with writes retained it says their commits must be replayed. materialize is the one place the loop resets and replays, and the loop's commit refuses a checkout that is not current, so a path that skips materialize fails instead of committing leftovers. Removed: recoverRetainedWrites, invalidateAndRefresh, refreshRemoteForResync, the duplicate replay tail, replayRequiredState, worktreeDirtyState, and the hasPendingCommits parameter. The resync prelude collapses to one materialize: its RefreshRemote branch and its default branch already did the same thing. No behavior change: the round-trip ledger is byte-identical and every test is green. A reset made outside the loop now also marks retained writes for replay instead of leaving them naming discarded commits. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * refactor(watch): drop ResyncRequest.RefreshRemote, which every resync already does A forced GitTarget recheck asked the worker to fetch the remote tip before its snapshot was judged. Every resync already fetches before it is judged, and the worker's two branches for it did the same thing, so the flag changed nothing from the watch stream through the coalescing to the worker. A forced recheck still restarts its streams; only the hand-off to the worker is gone. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * perf(git): undo a write that failed part-way without a fetch A write that failed after staging part of its change left the worktree dirty, and the next commit fetched and reset from the remote to clear it. The checkout is the projection of the retained writes, so the commit a batch started on is all the cleanup needs: a failed batch is now reset to it locally, its leftovers discarded, and base trust kept. Only a failed write that cannot be undone locally still leaves the worktree dirty for a reset from the remote, so a `recovery` fetch now points at a reset that went wrong, a parent change, or a replay that did not finish. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * fix(git): a decided window survives a remote that cannot be reached When retained writes needed a rebuild and its fetch failed, finalizing a window dropped it and failed the CommitRequest riding it; only a missing parent asked for a snapshot to re-derive the lost writes, and every new window spent a fetch retrying the rebuild. A closed window is now a decided write: it enters the log before it is committed, and materialize commits the decided writes not committed yet, after rebuilding the ones that were. A failure of the write itself (a refused plan, a write that cannot be made) is still terminal for that write alone; an unreachable remote leaves every decided write in the log for the publication retry, and the request riding one stays WaitingForPush. While the retry is pending, a decision that would need a connection to commit waits for it. The CommitEmpty record of a request that reached no window is decided the same way. A missing parent still drops the window to a snapshot until the log is bounded. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * refactor(git): one write path for every write the branch worker makes Review of the decided-window change found two defects and a structural gap. Windows and saves took decide -> materialize, while atomic batches, resyncs and refusal touches still took materialize -> commit -> retain; the executor re-entered itself through refusal handling; and pcr.committed came to mean "decided". Every write kind is now decided into the log and committed by materialize, in branch_log.go. One place classifies an attempt: committed, failed for good, or left for the retry because the remote could not be reached. A write's origin (the resync caller, the atomic request, the refusal a touch answers) rides with it, so its outcome is settled there. materialize is never re-entered: a refusal's empty commit decided while a refused write is settled is appended for the running pass to commit in order, and no push starts inside a pass. l.commit, retain, the commit guard, pcr.committed and rebuildPendingWrites are gone. Fixes from review: - A write committed later than its decision re-reads its prune policy, as a replay does. A delete decided during an outage deleted a file the operator had since set to prune: Never. - Parent recovery no longer opens an obligation with nothing owed. A save whose empty record failed for a missing parent left the target RecoveringParentBranch with nothing to publish. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * refactor(git): one retry schedule for everything the branch worker still owes A failed publication and a missing parent each kept their own deadline, and the two had to hand work back and forth: a failure while parent recovery was open deferred to recovery's deadline, or every new commit retried at once. One schedule, retry.go, replaces publicationRetry and parent recovery's backoff, next-probe time and timer. What is due when it fires decides the attempt: while parent recovery is open, one advertisement looking for the parent; otherwise, materializing the log and pushing it. Whoever observes a failed attempt schedules the next one, once, and a new parent latch starts the schedule over so the first probe is one initial backoff away, as before. The push timer is only the success cooldown again. publication_retry.go, deferToRecovery and the hand-off between the two clocks are gone. Retention is unchanged; the round-trip ledger is unchanged. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * fix(git): keep what a missing parent holds back, and bound it at admission A window, save or resync decided while the parent branch was missing was dropped; parent recovery remembered its (GitTarget, collection) scope, and once the parent returned the controller forced a recheck whose snapshot re-derived the cluster's state. That lost the live author and message of every dropped window, failed every save riding one, and needed per-scope bookkeeping to know when a snapshot had been published. Writes decided while the parent is missing now stay in the log like any other a remote failure holds back, and are published when the probe finds the parent. A resync the remote holds back answers its caller with the error at once and stays in its place, so the writes decided around it keep their order; resyncs are never replaced. Nothing is dropped, so nothing is owed a snapshot: parent recovery's scopes, awaitingPush, the snapshot-request sequence and the controller's snapshot-request tracker are gone. The log is bounded at admission instead. While its retained writes hold the branch's byte budget and a failed attempt waits for its retry, the worker refuses new writes, saves and resyncs through the existing queue-full contract: the watch records its cursor only after a write is accepted, so the reconnect delivers a refused event again. A healthy branch never closes. A pending retry now defers a new decision only until it is due. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * fix(git): push the empty commit a resync's refusal decides A refusal a resync discovers decides its empty commit while the resync's outcome is settled, inside the commit pass. Nothing pushes from inside a pass, and the resync's own caller schedules a push only when the resync committed, so the empty commit was made and never left the checkout. The refusal e2e caught it; the unit fixture pushed by hand and hid it. A write decided during a pass is now a follow-up: whoever started the pass schedules its push once the pass ends, and a pass started by the push itself publishes it with the rest. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * fix(git): a refused replay drops only its own entry A replay used to abort at its first error, so one retained write that the moved remote now refused blocked every write behind it indefinitely. replayPendingWrites undoes a refused write on its own, goes on with the rest, and stamps the entry with its refusal; checkoutApplied counts only the writes the checkout holds. After either replay (the loop's rebuild, the push cycle's after a rejection) the loop takes stamped entries out of the log and settles each as a refusal at first commit is settled: the refusal is reported and a save riding it fails. Any other failure still abandons the replay and keeps everything for the retry. A committed resync is now marked answered, so a replay that refuses it later reports the refusal on the target instead of answering its caller a second time. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * docs(design): pause intake and keep recovery running when a branch's Git is down Record the recovery contract for a saturated branch worker (pause new payloads, keep accepted work and the retry schedule, resume after the backlog settles), the three meanings of replay, and the source review's findings at 373bf8d that gate the next steps (dedup before admission, incomplete byte budget, resync fetches during backoff, polling watch recovery). Steps 5a/5b/5c split out; Redis stays deferred. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * fix(watch): a live event changes the watch's state only once the worker accepted it A refused UPDATE was lost on cursor resume: the content hash was recorded before routing, so the redelivered frame matched the hash of an event the worker never took, was skipped as unchanged, and advanced the cursor past it. The dedup check now reads the cache before routing and records the baseline only after Enqueue returned true, swapping from the entry the check saw so an overlapping stream's acceptance is never overwritten by a stale baseline (a conflict clears the entry: no baseline is safe, a wrong one is not). Two more holes on the same boundary: - the shutdown arm returned the never-enqueued event's resourceVersion, so the cursor moved past it; - runTargetWatch resumed from a cursor after the first session ended however it ended, so a stream whose snapshot the worker refused (admission backpressure) resumed from a previous stream's cursor and skipped its own replay, sweep and render-fidelity report. It now resumes only after its own replay recorded a cursor. EnqueueRequest is removed: it hid its enqueue boolean and had no caller. Step 5a of docs/design/gittarget-branch-worker-log.md, with the producer inventory and the limits left for 5b. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * docs(design): draw the event pipeline as it is built today A picture-first overview of the path from a watch frame to a pushed commit: watch stream replay/resume rules, the three meanings of "replay", resync coalescing and fences, the branch worker's inputs and window closing, the log's lifecycle, publication with a rejection, retry and admission, a save end to end, what is an event today, and an honest list of what is still missing and who owns it. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * fix(git): bound every call to a Git server, and settle a lost push reply by evidence Measured first against go-git v6.0.0-alpha.5 with servers that accept a connection and then stall: over HTTP, go-git's context-taking API returns at the deadline, but SmartFetchFrom, CheckRepo and the advertisement used the context-free List and Fetch and hung; over SSH, go-git uses the context only to dial, so the SSH handshake and every git-protocol read hung past an expired context, and worker shutdown waited with them. - listRemoteRefs, the fetch in SmartFetchFrom, CheckRepo and advertiseRemoteBranch use ListContext/FetchContext and take a context. - Each call adds a dialer whose connection closes when the call's context ends, which is what unblocks SSH. Nothing runs the operation on another goroutine, so nothing outlives it with the checkout. - gitCallTimeout (2m) bounds each advertisement, fetch or push session, inside the library functions, so the GitProvider controller's check is bounded too; gitPublishTimeout (5m) is one deadline over the whole push cycle, contention retries and replays included. - A push that fails without a rejection already probed the remote; when the probe finds the branch at our local head, the push landed and only its reply was lost, so the cycle settles as published instead of replaying (which landed a save's empty commit twice). Only the exact head counts; a remote that moved on past our commits still replays. runPushCycle's failure handling moves to afterFailedPush and its success bookkeeping to notePushSucceeded. Step 6 of docs/design/gittarget-branch-worker-log.md, with the measurement table. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * test(controller): wait for the WatchRule to mirror the settled GitTarget, not just Ready The #397 fix retried the direct reconcile until the rule's Ready was False/Progressing, but with no streams in envtest Ready is False/Progressing either way, so the wait could pass on its first try while the reconciler's cached read of the GitTarget still had no conditions, leaving GitTargetReady=Unknown. It recurred in CI on #413. The wait now also requires GitTargetReady False/Progressing, the condition the test asserts. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * docs(design): plan the unchanged filter as per-stream memory, for review Step 5a2 keeps the filter that drops Git-useless live UPDATEs (it guards commit windows against unattributed /status updates and keeps status churn out of the FIFO) but moves its memory from one process-wide map onto each stream. That removes the cross-stream compare-and-swap from 5a, frees entries with the stream, and closes a loss the shared memory has today: a replay inside a stream never updates it, so an object that returns to its pre-gap content after the replay is dropped as unchanged. Naming and the reset-versus-seed choice are left as decisions for review. The overview shows today's shared memory and the planned shape. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * fix(watch): refuse overlapping collections within one GitTarget A GitTarget now watches each object through one collection. Two rules whose collections overlap structurally (same type, and the same namespace or one of them all namespaces) are refused whatever their object selectors; before, only a selector disagreement was. An exact duplicate is one collection and still shares one stream; disjoint namespaces and separate GitTargets stay independent. Oldest-rule precedence and whole-rule refusal are kept. The reason is now CollectionOverlap (was ObjectSelectorConflict), and the message names both rules and both scopes. This is the prerequisite for giving each stream its own unchanged filter: with one stream per object, no second producer can deliver a stale copy into another author's window. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * fix(watch): give each stream its own desired-state change filter The unchanged filter was one process-wide map shared by every stream, coordinated by compare-and-swap between overlapping streams, and a replay never updated it. Two defects followed: after a replay found Z, a live return to the pre-replay content X matched the stale baseline and was dropped, leaving Git at Z; and a replayed object had no baseline, so its first status-only update reached the worker unattributed and could split another author's commit window. desiredStateChangeFilter is a UID-to-hash map owned by one stream, kept across its reconnects and released with it. A live event's hash is recorded only once the worker accepted it, and an accepted DELETE clears the UID. Each replay, initial-events or LIST fallback, gathers hashes with the same sanitizer and replaces the map only once the worker accepted the snapshot; a refused or unfinished replay installs nothing. With overlapping collections refused per GitTarget, the stream is the only producer for an object, so Manager.liveContentDedup and its compare-and-swap are gone. The unchanged outcome and the step 5a accepted-event and cursor guarantees are kept. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * test(watch): wait for a test's target watch goroutines before it returns Cancelling a stream returns before its goroutine finishes its last session, which still records metrics. A test that returned on cancel left that goroutine reading the global exporter while the next test reset it, so `go test -race ./internal/watch` failed: once through the new replacement-stream overlap test, and once through an older plan test. The manager now counts the goroutines running a target watch, and the tests that start real streams wait for them in cleanup. The package passes under -race. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * fix(git): charge every retained write against the budget, empty ones included Admission closes when the log holds the retained-byte budget during an outage, but the log was charged only each write's payload. A save's empty record and a refusal's empty commit carry none, so a branch whose remote was down kept admitting saves against a budget it never reached: ten empty saves were retained against a one-byte budget at zero bytes. Every decided write is now charged its payload, its message, and a fixed overhead for its bookkeeping. The charge is fixed at the decision and refunded exactly when the write leaves the log. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * fix(git): a resync during backoff waits for the retry instead of dialing decide let a resync materialize while a failed attempt waited for its retry, because its caller is waiting to hear what it found. Each resync then spent a fetch before the retry deadline, and with slow failures each one held the shared worker for the length of that call. A write decided behind a retained resync reached the same fetch through the pass. The retry schedule now records the failure it is waiting out. A resync during backoff is answered at once with that failure, as one the remote refused is, and stays in the log; it is applied when the retry is due. A write behind an uncommitted resync is no longer treated as local. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * fix(git): a released resync marker runs the request coalesced into it A resync coalesced into a queued marker is told it was enqueued, and the marker's own request is answered as superseded. When a write then queued behind the marker made a newer resync take its own slot, the key was released and the marker ran the request it first carried: the one already answered. The coalesced request was never run and never answered, so its caller waited out its timeout for a reply that could not come. Git still converged through the newer resync. A released marker now runs the request it held when it was released. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * fix(git): bound accepted work at intake, and pause it until a push lands During an outage the budget was read once per loop iteration against what the loop already held, so producers could fill the whole FIFO between two iterations however far past the budget that went. It also counted neither queued payload, deferred heals, nor saves waiting for a window, and it reopened as soon as the log dipped below the budget, even while the remote still refused pushes. An intake gate now charges every write, save and resync at enqueue: its payload, sized once by the producer off the loop, plus a fixed overhead per item, so the budget bounds the item count too. The loop publishes what it holds: the window, the log, deferred heals and waiting saves. While a retry is pending, a payload that would cross the budget is refused and pauses the branch. The pause is a latch, released only when the retry clears; room under the budget again or a remote that can be read but refuses the push keep it. A snapshot larger than the whole budget is refused during an outage with a message naming both sizes, and accepted once the branch publishes again. Withdrawals, refresh ticks and shutdown are lifecycle work and never pass the gate. IntakePaused returns a channel closed when intake reopens, for producers to wait on. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * fix(watch): a stream on a paused branch waits for intake to reopen A target watch whose session ended reconnected after its two-second backoff, whatever the reason. On a branch that had paused intake that meant gathering a snapshot, or delivering an event, that the branch refused again, every two seconds for as long as the outage lasted. A stream now waits on the branch's IntakePaused channel before reconnecting, looks again after every wake-up because the branch can pause again first, and falls back to a one-minute re-check. Its cursor stays where the last accepted event left it. Marks step 5b built in the branch-worker log plan, and updates UPGRADING, interpreting-metrics and the CommitRequest spec for the intake budget. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * docs(design): draw the event pipeline as it is after step 5b The overview now shows the intake gate and its pause latch, the watch stream waiting for a paused branch instead of reconnecting every two seconds, the retry deadline answering a resync with the failure it waits out, and the coalescing fix. The gap list keeps only what 5b left open: the budget counts serialized bytes, a healthy branch's FIFO is bounded by count, and loop-derived work can overshoot by a bounded amount. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * feat(status): report a branch that cannot publish on its GitTargets and held saves Through a Git outage a GitTarget reported Ready=True, and once intake paused it reported Stalled=True with WatchError, because its refused streams were graded as broken watches. A save waiting for its push said only that it was waiting. The branch worker now publishes one report: whether a failed attempt waits for its retry, since when (stable across retries), the last cause, and whether intake is paused. It is replaced, and the branch's GitTargets enqueued, only when one of those changes, so a long outage writes no status per retry. Every GitTarget on the branch reports Ready=False, Reconciling=True, Stalled=False under Progressing, with the start, the cause and the pause in the message; terminal gates still win, and a missing parent is left to ParentBranchNotFound. A stream that waits for its branch is graded Replaying/BranchIntakePaused. A save in WaitingForPush carries the same message. New metrics: git_retained_bytes, git_retained_writes, git_intake_paused, git_oldest_retained_write_timestamp_seconds and git_next_retry_timestamp_seconds, read at scrape time, and git_materialization_failures_total{reason} for the failure before any push cycle. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * docs(design): mark step 5c built, and leave step 7 The branch-worker log plan records what step 5c built and points the next-step prompt at step 7. The pipeline overview describes the publication report and drops the status gap it closed. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * docs: close the branch-worker log plan, and say what a branch does through an outage Step 7 of the plan. Architecture gains a section on a remote that cannot be reached: decided writes are kept and retried on one schedule, every Git call is bounded, the outage budget pauses intake until a push lands, and every GitTarget on the branch reports it. The event model, the state of affairs page, the HA plan's prerequisite, the CommitRequest spec, and INDEX now say what #413 built and what is left: recording the other FIFO inputs as transitions, then persistence. The plan is marked built and stays in docs/design, because its recovery contract is still the reference other pages link to. write_gate.go's effective-point comment already matched what was built and is unchanged. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * fix(git): drive the log from one place, and charge what the branch keeps Review of fc02f51 reproduced four defects, and asked for one structural step. decide now only appends. One driver, advance, runs at the end of every wake: it materializes what was decided, schedules the push, and closes the retry and parent recovery once the log is empty. Handlers no longer commit or push, so the materializing, followUps and deciding flags and decision numbering go. - Recovery ends when nothing is owed. A held resync that found nothing to change once the parent returned emptied the log without a push, and left recovery, its retry and the intake pause open for good. - A handled item's charge moves from queued to held in one locked step. It was released before the loop published what it held, so a producer in between found room the branch did not have. - The FIFO holds a resyncMarker with the current request and its charge. A marker used to be the first request of its key, so the queue kept every snapshot coalescing replaced; releasedResyncs is gone. - A window charges each event it keeps, deletes included, and the save attached to it. A decided write is never charged more than the window or save it came from. Every commit now re-reads its write's prune policy, from the informer cache. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * test(git): pin how two edits to one object replay onto a remote holding the last Each decided write is judged against the tree the one before it left, so two edits to one object replayed onto a remote that already holds the second one's content land as a revert and a reapply. The final tree is right, and each decision keeps its commit and the save riding it. This is accepted rather than collapsed, which would cost a save on the first edit its commit; the design doc says so next to the replay contract. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * fix(git): clear the slot a write leaves, so its payload leaves memory with it removeAt shortened the log in place without clearing the vacated slot of its backing array, so a resync that committed nothing kept its whole snapshot reachable while the budget said the branch held nothing. slices.Delete clears it. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * refactor(git): call what a branch worker holds its pending writes "Log" crept into the domain on this branch for something that was never new: the ordered pendingWrites the worker already had. It also names diagnostic logs and suggests a durable journal, which this is not. - branch_log.go is pending_writes_loop.go, beside pending_writes.go, as commit_request_attach_loop.go sits beside commit_request_attach.go. - gittarget-branch-worker-log.md is gittarget-branch-worker-pending-writes.md, and every link follows it. - Comments, log messages, test names and docs say pending writes; decide, materialize and publish keep their names. - definitions.md defines "pending write" and rules out "log" and "journal" for it. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * refactor(git): name what a refused enqueue is, and two loop names for what they do A refused enqueue is not lost work any more: the watch keeps its cursor and delivers the event again, the controller re-sends a save, a resync is gathered again, and the next reconcile asks for a refresh. It costs a write's own commit only when its watch cursor expires first. The metric guide, its alert, the outcome classes, the chart's queue-depth help and the comments still called it loss; they now call it a refusal, and route_failed and git_queue_drops_total move to the recoverable class. The alert fires on a healthy branch only, since an outage's refusals are the intake pause, which has its own. - PendingWrite.materialized is committedOnce: it stays set after a reset discards the commit, so it never meant the checkout holds it. - settleUnreachable is replyToDeferredResyncs: it settles nothing, it answers the callers of resyncs that stay pending. - The HA plan and push-cooldown no longer list built work as outstanding, and a telemetry comment no longer says writes stay in the log. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * refactor(git)!: rename git_queue_drops_total to git_queue_refusals_total A refused enqueue is not lost: its producer offers the work again, and only a watch cursor that expires first costs a write its own commit. The counter also counts refusals while a branch has paused intake, not only a full queue. Its name said otherwise, so it now says refusals. The labels are unchanged. BREAKING CHANGE: gitopsreverser_git_queue_drops_total is no longer emitted; dashboards and alerts must use gitopsreverser_git_queue_refusals_total. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * docs(metrics): say that recovery after an expired cursor follows the prune policy A refused write whose watch cursor expires is recovered by a fresh snapshot, which restores current content but cannot infer a delete from absence under the default prune.mode OnEvent: the deleted object's file stays in Git. The metric guide, the counter comments, the queue-depth help and the upgrade note said only the write's own commit was lost; they now say both, and the guide links the recovery contract.

What this is
A vocabulary for the project, and the breaking release that makes the API follow it.
docs/definitions.mdis the third rulebook, next tostyle-guide.mdfor prose andconfig-flag-conventions.mdfor flags. It gives each concept one name, sets nine rules for naming a kind, field, condition type, reason, enum value or printer column, and lists the words we do not use. It binds: a name that breaks a rule is a defect.v1alpha3. No conversion, and no alias kept for any old spelling. The plan, with the reasoning for each item, isdocs/design/vocabulary-cleanup.md, now marked built. The user-facing migration is the new top entry indocs/UPGRADING.md.Nothing behaves differently. Every change is a name.
What changed on the API
Condition reasons. A reason no longer restates its own condition type.
GitPathAccepted,RenderMatchesLive,GitProviderReady,ClusterProviderReady,PushedandValidated, whenTrue, now report the shared FluxSucceeded.InClusterstays as the secondValidated=Truereason. On the rule kinds,GitRepoConfigNotFound(a kind that no longer exists) becomesGitProviderNotFound, andResourcesResolvedreportsSucceeded/CatalogNotReadyin place ofResolved/UnresolvedResources.Falsethere has only ever meant that the discovery catalog is not ready; a selector matching nothing resolvesTrue, watching zero types.Stalledbecomes Flux'sFailed, andSuspendednow aliases Flux's constant. The unusedReconciling,CheckingandGitRepoConfigNotReadyconstants are deleted, along with five test-only aliases that kept the oldStreamsReadyspelling alive.Printer columns. Columns that only showed another object's
Readyare removed:ProviderReadyandClusterProviderReadyonGitTarget(20 columns down to 18), andGitTargetReadyon both rule kinds.StatusbecomesMessageand sits second to last on all six kinds.FactsbecomesFactsReceived,TargetbecomesGitTarget,SHAbecomesCommit. Both rule kinds gain a wideResourcesResolvedcolumn.Status fields. A bare commit hash is called
commiteverywhere:CommitRequest.status.commit,GitTarget.status.remote.commit,status.placement.resolvedAtCommit.status.retention.lastChangedTimebecomeslastChangedAt.GitProvider.status.branches[].gitTargetsbecomesgitTargetCount.status.retention.modegets the same enum asspec.prune.mode. The two identical streams blocks merge into oneStreamsStatus, soGitTargetalso reportspendingSample. ACommitRequestthat had already finished is never reconciled again, so it keeps an emptystatus.commit; the commit is in Git. Insideinternal/git,RemoteObservation,LayoutReportandFinalizeResultcall the same valueCommit.Spec, flag and chart.
ClusterProvider.spec.qpsandspec.burstmove tospec.client.qpsandspec.client.burst.--allow-insecure-git-httpbecomes--insecure-allow-git-http, with the chart valuecontrollerManager.insecureAllowGitHTTP.controllerManager.gitRefreshIntervalbecomesgit.refreshInterval. The chart's values schema rejects the old keys, sohelm upgradefails and names them instead of silently ignoring them.The one rename that fails open
A
ClusterProvidermanifest that still setsspec.qpsorspec.bursthas those fields pruned on apply. The provider then falls back to the operator-wide--source-cluster-qps/--source-cluster-burst, so a cluster you throttled on purpose gets more traffic.UPGRADING.mdopens with a warning and gives akubectl | jqcommand to find these providers before upgrading.A correction to the plan
The plan said that a dashboard selecting
reason="GitPathAccepted"would go empty. It never matched anything to begin with:gitopsreverser_resource_conditiononly carries the reason ofReady,ReconcilingandStalled, andReady=Truewas alreadySucceeded. Three renamed reasons do reach the metric, because a rule'sReadycan carry them:GitRepoConfigNotFound,UnresolvedResourcesandStalled.UPGRADING.mdand the plan now name those three.The plan also named the rule kinds'
