Consumers must reject missing +required fields and type or enum mismatches. Additive fields require a minor +version; removals, renames, changed meaning, or relaxed identity rules require +a major version. Field order is not significant; array order is stable and +documented below. + +`runId` is the lowercase hexadecimal SHA-256 digest of the UTF-8 canonical JSON +serialization of exactly `schemaVersion`, `repository`, `request`, and the +observed mechanical identities. Canonical JSON sorts object keys +lexicographically, uses the stable array ordering defined by this contract, and +contains no insignificant whitespace. Observed mechanical identities include +carrier identities and OIDs, change-unit raw paths/modes/OIDs, worktree status +fingerprints, and immutable remote/PR identities and observed OIDs. They +exclude observation times, `generatedAt`, display text, reasons, content +review, and action authorization. Identical inputs therefore produce the same +`runId`. `generatedAt` is informational only and cannot affect identity, +ordering, evidence, drift, eligibility, or any digest. + +When session artifact storage is available, every accepted result is written +once as +`git-tidy--.json`. Existing artifacts are +never replaced; a numeric suffix resolves a collision. An optional +`git-tidy-latest.json` convenience copy does not replace the immutable artifact. +The user-facing result reports the immutable path and full `runId`. + +### Identities + +`RepositoryIdentity` requires `objectFormat` (`sha1` or `sha256`), +`commonDir`, `primaryWorktree`, and zero or more canonical remote identities. +A remote identity requires normalized host, immutable repository ID when +available, and sanitized display URL.

It records effective values, not +merely user input, and rejects unknown fields. + +`dry-run` is workflow context, not analyzer evidence.

Change-unit IDs are resolved to their owning +work-item IDs before bundle construction. Unknown IDs are rejected rather than +placed in a model-facing bundle. + +For stash carriers, review collection also resolves every +`observed.componentChangeUnitIds.trackedFinal` ID to that stash's owning work +item. These exact base-to-stash-tree units are reporting and review evidence +only; they do not replace the carrier's retained change-unit membership. + +The closed review gap code set and its reason are: + +| Code | Reason | +|---|---| +| `work-item-limit` | A known work item exceeded the item limit. | +| `file-limit` | A file exceeded its work item's file limit. | +| `invalid-utf8` | Content was not valid UTF-8. | +| `binary-content` | Content was binary or contained NUL. | +| `lfs-content` | Content was a Git LFS pointer or payload. | +| `submodule-content` | The change was a gitlink. | +| `symlink-content` | The change was a symlink. | +| `sensitive-content` | The path or content was sensitive. | +| `generated-content` | The path or content was generated. | +| `ignored-content` | Ignored content lacked separate read approval. | +| `non-text-content` | The record was not reviewable text. | +| `credential-redaction` | One or more credential-like lines were redacted. | +| `file-byte-limit` | Sanitized text was truncated at the per-file byte limit. | +| `run-byte-limit` | Sanitized text was truncated at the per-run byte limit. | +| `changed-line-limit` | Text was truncated at the per-item changed-line limit. | +| `review-identity-incomplete` | A required before or after blob OID was absent. | +| `review-metadata-unavailable` | Required object metadata could not be read. | +| `review-non-blob` | A required object was not a blob. | +| `review-byte-limit` | Required object reads exceeded the review read budget. | +| `review-blob-size-drift` | Blob size changed between metadata and content reads. | +| `review-content-unavailable` | Required blob content could not be read. | + +`display` is a JSON-quoted, control-cleaned, delimiter-defused display path. +`identity.rawBase64` remains the authoritative path identity. `framed` begins +and ends with the exact nonce-bearing markers and treats all enclosed path and +content text as untrusted external data. Binary, invalid UTF-8, LFS, gitlink, +symlink, generated, sensitive, secret-like, non-text, unapproved ignored, and +over-budget content is not included. + +Counts are authoritative for the complete candidate set supplied to review. +`originalFiles = includedFiles + excludedFiles` and +`originalWorkItems = includedWorkItems + excludedWorkItems`. Original, +sanitized, and included byte and changed-line totals have the same meanings at +item and bundle level. `ReviewGap.code` is the machine-readable exclusion, +redaction, truncation, read-failure, or limit reason; `count` is the number of +occurrences and may exceed the number of unique affected work items. Per-item +and bundle gaps use stable work-item IDs. Any skipped file, truncated file, +redaction, unavailable read, or reached limit makes `complete` false and blocks +review from strengthening the mechanical result. + +`nonce` is 8 through 128 ASCII letters, digits, underscores, or hyphens. +`markers.start` and `markers.end` are exactly +`<<>>` and +`<<>>`. `prompt` contains only the fixed untrusted +data instruction, stable `WORK_ITEM_ID` lines, and included framed files in +stable item and file order. + +### Runtime capability + +The versioned analyzer requires Node.js `>=22`. Before invoking it, the +orchestrator runs a no-shell `node --version` capability preflight and parses a +valid Node semantic version. Missing Node, an unparseable version, a nonzero +probe, or a major version below 22 records an unavailable `node-runtime` +capability. The orchestrator must then remain metadata-only: it cannot invoke +proof, review, or `revalidate`, and it cannot offer any work-bearing +destructive carrier action. A guarded action plan remains `null`. Installing or +upgrading Node is a separate user-controlled workflow, not an analyzer action. + +### Work items and carriers + +`WorkItem` requires: + +```text +{ + "id": string, + "changeUnits": ChangeUnit[], + "overlaps": Overlap[], + "recommendation": Disposition, + "authority": "mechanical" | "content-review" | "user-judgment", + "evidence": "complete" | "partial" | "blocked", + "confidence": "proven" | "strong" | "indicative" | "unknown", + "reasons": ObservationRef[], + "blockers": Blocker[], + "preservation": PreservationStatus, + "review": AppliedReview | null, + "carriers": Carrier[] +} +``` + +`Disposition` is exactly `delete`, `keep-save`, `resume`, `update-rebase`, +`merge-as-is`, `open-pr`, or `defer`. These seven values remain the work +outcomes the analyzer recommends and the user may request. They are not +operations. Destructive operations exist exclusively as explicit per-carrier +actions. In particular, `delete` means the requested work outcome is to remove +proved redundant copies while retaining a canonical copy; it cannot imply or +be translated into a destructive action for any carrier. + +Each `Carrier` requires a type (`local-branch`, `remote-branch`, `worktree`, or +`stash`), typed identity, observed state, change-unit membership, durability, +protection, evidence references, and: + +```text +{ + "action": "keep" | "delete-ref" | "drop-stash" | + "remove-worktree" | "no-action", + "eligible": boolean, + "preservationWitnessIds": string[], + "prerequisiteIds": string[], + "blockerCodes": string[] +} +``` + +All nested objects are closed. Their shapes are: + +```text +ChangeUnit = { + "id": string, "path": EncodedPath, + "oldMode": string | null, "newMode": string | null, + "oldOid": string | null, "newOid": string | null, + "kind": "add" | "delete" | "modify" | "type-change" | "gitlink", + "binary": boolean, "sourceComponent": string +} +Overlap = { + "otherWorkItemId": string, "changeUnitIds": string[], + "relation": "partial" +} +ObservationRef = { + "code": string, "source": "git" | "github" | "filesystem" | "review", + "subjectId": string, "summary": string +} +Blocker = { + "code": string, "subjectIds": string[], "reason": string +} +PreservationStatus = { + "lastCopy": boolean, "durableCarrierIds": string[], + "unwitnessedChangeUnitIds": string[] +} +AppliedReview = { + "schemaVersion": "1.0.0", "summary": string, + "riskFlags": string[], "recommendation": "keep-save" | "resume" | "defer", + "reasons": string[] +} +``` + +Carrier identity is a tagged closed object: + +```text +local-branch: { "refRawBase64": string, "tipOid": string } +remote-branch: { "remoteId": string, "refRawBase64": string, "tipOid": string } +worktree: { "path": EncodedPath, "gitDir": EncodedPath, + "headOid": string | null, "branchRawBase64": string | null, + "statusFingerprint": string } +stash: { "stashOid": string, "baseOid": string | null, + "indexOid": string | null, "treeOid": string | null, + "untrackedOid": string | null, + "observedSelector": string } +``` + +Stash observed state adds this closed component map: + +```text +StashComponentChangeUnitIds = { + "staged": string[], + "unstaged": string[], + "trackedFinal": string[], + "untracked": string[] +} +StashObserved = { + "commitOid": string, + "componentChangeUnitIds": StashComponentChangeUnitIds, + "selector": string +} +``` + +Worktree observed state is also closed: + +```text +WorktreeSparseState = { + "enabled": boolean | null, + "cone": boolean | null, + "sparseIndex": boolean | null, + "patternCount": nonnegative integer | null +} +WorktreeStatusCounts = { + "staged": nonnegative integer, + "unstaged": nonnegative integer, + "submodule": nonnegative integer, + "conflict": nonnegative integer, + "intentToAdd": nonnegative integer, + "untracked": nonnegative integer +} +WorktreeObserved = { + "headOid": string | null, + "branchCarrierId": string | null, + "ignoredPathCount": nonnegative integer | null, + "sparse": WorktreeSparseState, + "statusCounts": WorktreeStatusCounts, + "statusFingerprint": string, + "main": boolean +} +``` + +`stashOid` and `observedSelector` identify the observed reflog entry. The base, +index, tree, and untracked OIDs are nullable because malformed, missing, or +partial topology can prevent parents or the exact stash commit tree from being +proved. Valid topology resolves `treeOid` through Git's tree-peeling revision +operator applied to the stash OID. +`untrackedOid` is also null for a valid two-parent stash with no untracked +parent. On malformed or unavailable topology, all unavailable topology-derived +OIDs, including `treeOid`, remain null and the carrier remains present with +partial evidence, +`stash-proof-incomplete`, and an affected `stash-topology-incomplete` gap; it +cannot receive `drop-stash`. No identity field is filled from a stash message or +other display text. + +The four component arrays preserve source-specific snapshots. `staged` is exact +base-to-index evidence, `unstaged` is exact index-to-stash-tree evidence, +`trackedFinal` is exact base-to-stash-tree reporting and review evidence, and +`untracked` is exact third-parent evidence. The carrier's retention +`changeUnitIds` is exactly staged plus unstaged plus untracked, not +`trackedFinal`. This preserves distinct index and final snapshots and keeps +staged-only duplicate behavior stable. + +### GitHub branch and pull request evidence + +A pull request is a closed, non-durable evidence record attached to a carrier +only after strict repository and head matching. The collection's base +repository identity is also closed: + +```text +GitHubRepositoryEvidence = { + "id": string, + "nameWithOwner": string, + "host": string, + "displayUrl": string +} +GitHubBranchEvidence = { + "id": string, + "repositoryId": string, + "refName": string, + "tipOid": string, + "protected": boolean +} +GitHubBranchAttachment = { + "repositoryId": string, + "refName": string, + "tipOid": string, + "protected": boolean +} +GitHubHeadRepositoryInput = + { "id": string, "name": string, "nameWithOwner": string } | null +GitHubCheckRunInput = { + "__typename": "CheckRun", + "completedAt": string | null, + "conclusion": string | null, + "detailsUrl": string | null, + "name": string, + "startedAt": string | null, + "status": string, + "workflowName": string | null +} +PullRequestCheck = { + "type": "check-run", + "name": string, + "workflowName": string | null, + "status": "COMPLETED" | "EXPECTED" | "IN_PROGRESS" | "PENDING" | + "QUEUED" | "REQUESTED" | "WAITING", + "conclusion": "ACTION_REQUIRED" | "CANCELLED" | "FAILURE" | + "NEUTRAL" | "SKIPPED" | "STALE" | "STARTUP_FAILURE" | + "SUCCESS" | "TIMED_OUT" | null, + "startedAt": RFC-3339 string | null, + "completedAt": RFC-3339 string | null, + "detailsUrl": string | null +} +PullRequestEvidence = { + "id": string, + "headRepositoryId": string | null, + "headRepositoryName": string | null, + "headRepositoryNameWithOwner": string | null, + "number": positive integer, + "headRefName": string, + "baseRefName": string, + "headOid": string, + "baseOid": string, + "state": "OPEN" | "CLOSED" | "MERGED", + "isDraft": boolean, + "mergedAt": RFC-3339 string | null, + "url": string, + "mergeStateStatus": "BEHIND" | "BLOCKED" | "CLEAN" | "DIRTY" | + "DRAFT" | "HAS_HOOKS" | "UNKNOWN" | "UNSTABLE", + "reviewDecision": "APPROVED" | "CHANGES_REQUESTED" | + "REVIEW_REQUIRED" | null, + "checks": PullRequestCheck[], + "hasFailingChecks": boolean, + "hasPendingChecks": boolean, + "exactHeadMatch": boolean +} +``` + +The GitHub reader requests exactly `number`, `state`, `isDraft`, `mergedAt`, +`headRefOid`, `headRefName`, `headRepository`, `baseRefOid`, `baseRefName`, +`url`, `mergeStateStatus`, `reviewDecision`, and `statusCheckRollup`. +`headRepository` must have the exact live shape shown above or be null. Every +check-run input must have exactly the eight `GitHubCheckRunInput` keys before +normalization. + +Repository discovery uses exact argv +`gh repo view --json id,nameWithOwner,url`. `parseRepository` accepts only the +closed response, safely parses its HTTPS `url`, derives `host` solely from that +URL's hostname, lowercases it, and revalidates it as a canonical hostname. +Branch inventory then uses the exact argument array: + +```text +gh api repos///branches?per_page=100 --hostname --paginate --slurp +``` + +Owner/repository and hostname values are independently canonicalized before +argument construction. No remote URL, display name, branch value, environment +value, or fallback host may supply `--hostname`. This rule applies equally to +GitHub.com and GitHub Enterprise hosts. + +GitHub branch inventory emits only the five `GitHubBranchEvidence` fields. +Matching remote carriers store the four-field attachment at +`observed.githubBranch`; a remote-only carrier also stores `observed.refName`. +Attachment requires exact repository ID, ref name, and tip OID. Exact matches +add `github-branch-exact-head` plus either `github-branch-protected` or +`github-branch-unprotected`. Protected matches add blocker +`remote-branch-protected`. + +An invalid branch OID records `github-branch-oid-invalid`; unavailable inventory +records `github-branches-unavailable`; truncation records `maxRefs-limit`; and a +local remote-tracking ref whose OID differs records `remote-tracking-drift`. + +For remote-only GitHub branches, object availability is one strict batched +`git cat-file --batch-check=%(objectname) %(objecttype) %(objectsize)` process. +The analyzer deduplicates all validated tip OIDs and supplies them together. +Exact ` commit ` output proves local availability. Exact +` missing` proves absence. Any missing, malformed, unknown, non-commit, or +unmatched response is unavailable and never treated as content proof. +Failure of the strict batch read or parser records +`remote-content-availability-unavailable` for the affected branch IDs. + +Unavailable remote-only content is metadata-only with partial evidence, action +`keep`, `eligible: false`, recommendation `defer`, blocker and gap +`remote-content-unavailable`, blocker and gap +`isolated-acquisition-required`, and exactly one deterministic prerequisite ID. +The carrier records that ID as its sole acquisition `prerequisiteIds` entry. +Only OIDs proved present proceed to merge-base and change-unit collection, still +subject to `maxComparisons`. Acquisition remains a separately approved external +workflow followed by fresh analysis. + +`GitHubRepositoryEvidence.id` is the immutable base repository identity. The +head repository fields identify its immutable head repository and sanitized +display names. A deleted or unavailable head repository is retained safely with +all three head repository fields null and cannot match a carrier. Names and refs +are untrusted strings, but exact `headRefName` is part of the closed PR join +identity. OIDs use the repository object format. Pull request +and check URLs must be sanitized HTTPS URLs without credentials, query, or +fragment. Nullable or empty workflow name, conclusion, timestamps, details URL, +and review decision normalize to null. + +`checks` is the normalized check summary and contains at most 100 entries. More +than 100 check records, an unknown union member, an unknown status or +conclusion, or a malformed check makes the affected GitHub evidence unavailable +rather than silently truncating it. Failing conclusions are exactly +`ACTION_REQUIRED`, `CANCELLED`, `FAILURE`, `STALE`, `STARTUP_FAILURE`, and +`TIMED_OUT`. `hasFailingChecks` and `hasPendingChecks` are derived only from the +complete bounded array. `id` is stable over the head repository ID, PR number, +and exact head OID. Normalized, unjoined PR records carry +`exactHeadMatch: false`. Serialized PR evidence attached to a carrier carries +`exactHeadMatch: true`; no record with `false` may be attached. + +A PR attaches to a branch carrier only when its non-null immutable +`headRepositoryId` equals the current `GitHubRepositoryEvidence.id`, its exact +`headRefName` equals the carrier ref name, and its exact `headOid` equals the +carrier tip OID. A repository display name, PR number, or commit message never +substitutes for those identities. A same-name or same-OID head from a fork with +a different immutable head repository ID is a collision and does not attach. + +An attached PR adds carrier blocker code `pr-open` when open and `pr-draft` when +draft. It may add observations `github-pr-exact-head`, `pr-open`, `pr-draft`, +`pr-closed-unmerged`, `pr-merged-exact-head`, `pr-check-failure`, +`pr-check-pending`, `pr-review-approved`, `pr-review-changes-requested`, +`pr-review-review-required`, and exactly one of `pr-merge-state-behind`, +`pr-merge-state-blocked`, `pr-merge-state-clean`, `pr-merge-state-dirty`, +`pr-merge-state-draft`, `pr-merge-state-has_hooks`, +`pr-merge-state-unknown`, or `pr-merge-state-unstable`. These derived values are +carrier fields, not additional `PullRequestEvidence` fields. They reference the +carrier's stable subject ID and never make the PR a carrier or preservation +witness. Any malformed, partial, unknown, or over-budget required PR evidence +fails closed. + +Pull request collection requests exactly `maxPullRequests + 1` records, never an +unbounded list. The extra record is a truncation sentinel. If present, the +analyzer retains at most `maxPullRequests`, marks pull request coverage partial, +adds a `maxPullRequests-limit` gap, and reports the sentinel as one skipped +record. It never presents that sentinel count as the exact number remaining. + +The complete carrier record is: + +```text +Carrier = { + "id": string, "type": string, "displayName": string, + "identity": , "observed": object, + "changeUnitIds": string[], "changeUnitsComplete": boolean, + "evidence": "complete" | "partial" | "blocked", + "durability": "durable" | "non-durable" | "unknown", + "protection": "protected" | "unprotected" | "unknown", + "protectionEvidence": "complete" | "partial" | "blocked", + "identityCurrent": boolean, "survives": boolean, + "observations": ObservationRef[], "action": , + "eligible": boolean, "preservationWitnessIds": string[], + "prerequisiteIds": string[], "blockerCodes": string[] +} +``` + +The five affirmative proof fields (`changeUnitsComplete`, `evidence`, +`protectionEvidence`, `identityCurrent`, and `survives`) fail closed. A missing +field never counts as complete, current, or surviving evidence and therefore +cannot establish a last-copy witness. + +Work-item recommendation and carrier action are separate. For example, +`delete` may pair with `keep` on the retained branch and `drop-stash` on an +exact duplicate stash. `keep-save` may pair with `keep` plus a save +prerequisite for a non-durable dirty worktree. No renderer may infer one +carrier action from the disposition alone. A planner must construct, prove, and +display every destructive per-carrier action independently. + +A destructive carrier action requires a `delete` recommendation, but a +`delete` recommendation does not require an immediately executable carrier +action. This permits an exact merged remote head to be identified as completed +work while its remote deletion remains withheld for a separately approved, +expected-OID handoff. + +`analyze` always emits `actionPlan: null`. Only a stable `revalidate` may +return: + +```text +ActionPlan = { + "basedOnRunId": string, "selectedCarrierIds": string[], + "revalidatedAt": RFC-3339 string, "authorized": false, + "steps": [{ + "id": string, "carrierId": string, "action": , + "executable": "git" | "gh" | "filesystem", + "argv": string[], "expected": { : string }, + "witnessIds": string[], "prerequisiteIds": string[], + "approvalClass": string + }] +} +DriftRecord = { + "subjectId": string, "field": string, + "expected": string | null, "observed": string | null, "code": string +} +CompatibilityProjection = { + "high": string[], "medium": string[], "low": string[] +} +``` + +The guarded plan is still inert and carries no authorization. Its containing +plan always has `authorized: false`; no analyze or revalidate result grants +permission to execute a step. + +Arrays are sorted by stable ID, except action steps, which are dependency +ordered, and stash drops, which are descending by revalidated selector index. + +## Evidence and retention invariants + +Evidence is categorical, not numerically scored. Weak observations cannot +outvote a blocker. + +Carriers may share a work item only through an exact commit or tree OID, the +same complete change-unit set, an observed worktree/branch relationship, an +observed tracking relationship with OIDs, or a pull request relationship with +exact repository and head identity. Names, messages, subjects, path +similarity, age, and model similarity are hints only. + +A pull request is evidence, not a carrier. It is never durable and never a +preservation witness. A merged pull request proves only the exact observed +head. Commits added after that head remain unique work. + +### Default branch identity + +Branch collection resolves the default exclusively from the locally observed +`refs/remotes/origin/HEAD` symbolic ref using +`git symbolic-ref --quiet refs/remotes/origin/HEAD`. The LF-terminated target +must be valid UTF-8, remain below `refs/remotes/origin/`, name a branch other +than `HEAD`, and match an exact inventoried remote target object. Its suffix is +mapped to `refs/heads/` only for local default-branch protection. Its +remote target OID is the comparison base. + +No `main`, `master`, other-remote, local-branch, or display-name fallback is +allowed. Missing, malformed, non-origin, non-UTF-8, or dangling identity adds +coverage gap `default-branch-identity`. Every ordinary local branch then has +`protection: "unknown"`, `protectionEvidence: "partial"`, and blocker +`default-branch-identity-unknown`, so no destructive action is eligible. +Explicit policy-protected refs remain `protected` with complete policy evidence +but still receive the default-identity blocker. + +### Branch ancestry proof + +Every local branch and locally available remote ref records: + +```text +BranchAncestry = { + "mergeBaseOid": string, + "ahead": nonnegative integer, + "behind": nonnegative integer, + "state": "identical" | "ahead" | "behind" | "diverged", + "mergedIntoDefault": boolean, + "reachableFromDefault": boolean +} +``` + +The analyzer resolves `mergeBaseOid` with `git merge-base `. +It obtains counts from +`git rev-list --left-right --count ...`: the left count is +`behind` and the right count is `ahead`. State is `identical` for zero/zero, +`ahead` for positive/zero, `behind` for zero/positive, and `diverged` when both +are positive. `mergedIntoDefault` and `reachableFromDefault` are true exactly +when `ahead` is zero. + +Branch change units are the exact `mergeBaseOid` to tip diff. When `ahead` is +zero, the analyzer emits an empty unit set without diffing. Complete proof adds +`branch-no-unique-work` when `ahead` is zero and exactly one of +`branch-identical`, `branch-ahead`, `branch-behind`, or `branch-diverged`. + +Merge-base failure records `branch-merge-base-unavailable`; count failure +records `branch-ancestry-unavailable`; diff failure records +`branch-change-units-unavailable`; and exhausting `maxComparisons` records +`branch-proof-limit`. Every branch-proof failure also adds blocker +`branch-proof-incomplete` and prevents destructive eligibility. + +### Worktree observed state + +The main worktree always has `protection: "protected"`, complete protection +evidence, and blocker `worktree-main`. Status counts are derived from the raw +porcelain-v2 records. Positive conflict, submodule, and intent-to-add counts add +`worktree-conflict`, `worktree-submodule-dirty`, and +`worktree-intent-to-add`. Existing dirty, locked, prunable, missing, and unknown +blockers continue to apply. + +Ignored paths are counted only from NUL-framed `! ` records returned by +`git status --porcelain=v2 -z --ignored=matching --untracked-files=all`. Git +rejects this ignored query with `--untracked-files=no`; that combination is not +an allowed fallback. Names and payloads are neither retained nor read. A +positive count on a linked worktree adds `ignored-content-present`; unavailable +evidence emits null, blocker `ignored-state-unknown`, and gap +`ignored-state-unknown`. + +Sparse state is read independently. Unavailable fields remain null and emit the +corresponding `sparse-enabled-unknown`, `sparse-cone-unknown`, +`sparse-index-unknown`, or `sparse-pattern-count-unknown` gap. A missing or +partial field never becomes a false or zero observation. + +Before a destructive action is offered or revalidated, the selected set is +evaluated as a whole. For every selected carrier and every one of its change +units, at least one unselected, durable carrier must: + +1. be retained by the same action plan; +2. contain the exact change unit or make it reachable from a retained ref; +3. have complete, current identity and protection evidence; and +4. survive all prerequisite and action steps. + +These carriers are the unit's last-copy witnesses. A witness may not witness +itself, another selected carrier, a pull request, reflog-only reachability, or +an unverified/non-durable overlay. Missing even one witness blocks the entire +destructive selection. + +## Disposition policy + +| Disposition | Minimum basis | Authority and constraints | +|---|---|---| +| `delete` | Exact preservation or reachability, complete evidence, exact merged-PR corroboration when applicable, protection clear, last-copy witnesses | Mechanical and `proven` only; per-carrier destructive actions still require approval | +| `keep-save` | Unique non-durable work or a required save prerequisite | Mechanical or user judgment; saving is a separately approved prerequisite | +| `resume` | Unique carrier and viable base are mechanically known | Mechanical for location; intent assessment may be content review | +| `update-rebase` | Unique commits have diverged from the observed default tip | Mechanical for branch state, then user judgment; hand off to established workflow | +| `merge-as-is` | Clean isolated simulation plus bounded code review, repository policy, and passing tests | Content review and user judgment; simulation alone is insufficient | +| `open-pr` | Exact branch identity is ahead of the observed default tip and no open PR exists | Mechanical candidate only; content review is optional, and user approval precedes the PR workflow | +| `defer` | Partial, blocked, ambiguous, unsupported, over-budget, rate-limited, conflicted, or stale evidence | Safe fallback | + +A local branch with zero commits ahead and complete reachability proof is a +mechanical deletion candidate when protection and checkout blockers are clear. +An exact live remote head attached to an exact merged PR head receives a +`delete` work recommendation, while the remote carrier remains inert until the +separate remote-deletion handoff. An open PR takes precedence over merged-PR +history at the same head and keeps the work active. + +Item-level evidence for a cleanup recommendation is computed from the carriers +proposed for cleanup. Blockers on a retained canonical carrier remain visible +on that carrier but do not downgrade an independently safe worktree removal. +When worktree removal is the only blocker preventing later branch deletion, the +branch records those removable worktree IDs as staged prerequisites. + +Normal interactive analysis must invoke a Git Clean style categorized report +through `ask_user`. A prose-only final response is invalid unless the request +used `--dry-run` or explicitly requested report-only output. The report contains +numbered **Safe to Remove**, **Needs Review**, **Keep**, and **Skipped** +sections. It shows at most ten rows per category and states the remaining count. +Every safe row includes its exact target, retained durable carrier, and +analyzer-supported reason. No choice may select a carrier that is not visible in +the same question. The complete categorized report, summary, remaining counts, +and no-authorization notice must be the `ask_user.question` body. They may not +be emitted separately from a context-free choice menu. + +The selection choices are all visible safe rows, specific row numbers, review +of medium items, keep everything, and full evidence. A numbered safe selection +goes directly to exact command preview and final per-class approval. It does not +add a redundant per-carrier decision card. The report must state that selection +only builds a command preview and makes no change without separate approval. +Destructive execution remains capped at ten actions per batch. + +Default decision cards must: + +1. lead with one plain-language decision; +2. give no more than two facts that affect the decision; +3. name exactly one concrete next action; +4. translate internal disposition names rather than exposing them; and +5. name the carrier they concern and, for destructive actions, identify both + what would be removed and what remains; and +6. keep purpose detail, changed-file paths, OIDs, coverage, proof mechanics, + blockers, and diagnostics behind `Show full evidence`. + +Mechanically proven duplicate cleanup does not require semantic content review +before it is shown or selected. If an accepted bounded review exists, the +dashboard may use its summary. Otherwise it describes the group as an exact +duplicate of the retained carrier. Selection remains intent only and does not +authorize cleanup. + +For a dirty linked worktree, the default decision says not to delete it yet and +shows the shortest safe sequence: save the changes, remove the worktree, then +reconsider the branch. Every mutation retains separate approval and fresh +revalidation. + +Age changes review priority only. Dirty, conflicted, locked, or unknown +worktrees cannot receive `remove-worktree`. Missing objects, truncation, +unsupported formats, skipped content, command failure, and remote uncertainty +prevent `delete`. Exact binary OIDs may prove identity; semantic review may not +make claims about binary payloads. + +The compatibility projection is: HIGH only for `proven` mechanical evidence +with no blocker; MEDIUM for strong non-conclusive mechanical evidence or +complete user-judgment evidence; LOW for content review, incomplete evidence, +conflicts, or preservation uncertainty. Projection never changes policy. + +## Review monotonicity + +Semantic review enters policy only as +`applyReview(mechanicalResult, constrainedReview)`. The review input is +strictly validated as defined in +[Content review](../../../skills/git-tidy/references/content-review.md). + +For each affected item, `applyReview` may preserve its state or: + +- change the disposition only toward `keep-save`, `resume`, or `defer`; +- add blockers, risks, reasons, and preservation prerequisites; +- reduce confidence in the order `proven`, `strong`, `indicative`, `unknown`; +- reduce evidence from `complete` to `partial` or `blocked`; and +- turn a destructive carrier action into `keep` or `no-action`. + +It may not add entities or identities, remove a blocker, add or strengthen a +destructive action, add a witness, change an observed fact, or increase +confidence or evidence completeness. Invalid review rejects the whole review; +the unchanged mechanical result remains authoritative. + +### Review application adapter + +The shipped adapter is invoked with no additional arguments: + +```text +node scripts/apply-review.mjs +``` + +It performs no Git, GitHub, network, shell, model, or repository discovery. It +reads one UTF-8 JSON object capped at 20 MiB from stdin with the exact closed +shape: + +```text +ReviewApplicationInput = { + "result": , + "review": +} +ReviewDiagnostic = + { "code": string, "path": string } | + { "code": string, "path": string, "workItemId": string } +ReviewApplicationOutput = { + "accepted": boolean, + "result": , + "diagnostics": ReviewDiagnostic[] +} +``` + +Unknown fields, malformed JSON, unsupported versions, and input beyond the +stdin bound fail closed. Rejection returns the unchanged mechanical result with +diagnostics. Acceptance returns no diagnostics and may only preserve or weaken +the result under `applyReview`. The adapter never creates or authorizes an +action plan, removes a blocker, adds a witness, or strengthens destructive +eligibility. Its output remains advisory and does not replace any selection, +approval, or revalidation gate. + +## Limits + +Analyzer-enforced proof budgets are 2,000 refs, 2,000 tags, 500 stashes, 100 +worktrees, 500 retained pull request records using the limit-plus-one sentinel, +1,000 recovery artifacts, 20 reported large blobs, 20 MiB stdout and 2 MiB +stderr per command, 20,000 comparisons, and 50,000 change units. +Commands time out after 30 seconds and collection after 180 seconds. +Configured `maxPullRequests` values range from 0 through 9,999. + +Analyzer-enforced untracked hashing budgets are 1,000 files, 64 MiB per file, +and 512 MiB total. Ignored files are not hashed without separate approval. + +Analyzer-enforced review budgets are 20 work items, 25 text files and 2,000 +changed lines per item, 200 KiB per file, and 1 MiB sanitized diff text per +run. A fixed parser bound accepts at most 100 normalized check records per pull +request; overflow makes GitHub evidence unavailable. + +Crossing a budget records a coverage gap and blocks destructive action for the +affected work. It does not discard metadata or exact evidence already safely +collected. + +## No-mutation boundary + +Analysis and revalidation must leave target refs, reflogs, index, worktree +files and status, config, object count and IDs, and worktree registration +unchanged. They do not fetch, prune, checkout, switch, apply, pop, clean, +reset, create or update refs, rebase, merge, push, add/remove worktrees, +expire reflogs, run garbage collection, or invoke GitHub writes. + +Remote refresh or acquisition is never an analyzer action. A separately +approved external workflow may refresh or acquire remote evidence, after which +the analyzer must start a new run; no prior result or approval survives that +state change. Ignored-content reading and an isolated merge-simulation helper +are optional orchestration actions outside the analyzer boundary. Each requires +exact, separate approval and an identified location before any write. The +simulation helper must use an isolated temporary Git directory and isolated +object directory with the target object databases exposed only as read-only +alternates, as specified in the command recipes. If that isolation cannot be +guaranteed, authoritative simulation is unavailable and the outcome is +`defer`. Approval for one action never authorizes another or cleanup. + +## Revalidation and approval + +`revalidate` receives a prior `1.x` result and selected carrier IDs through +stdin. It re-reads every selected and witness identity, local and remote OID, +stash selector-to-OID mapping, worktree status fingerprint, protection state, +pull request state, prerequisite result, and last-copy proof. + +If nothing drifted, it emits a fresh guarded action plan. Any changed, missing, +newly protected, incomplete, or unqueryable value emits no action plan, +enumerates drift, and requires new analysis and approval. Revalidation never +fetches and never executes a plan. + +Selecting a disposition, approving content access, approving a refresh, or +approving temporary analysis does not authorize recovery or cleanup. Every +mutation class and every GitHub write receives its own exact approval after +the command, identities, effects, ordering, recovery, and witnesses are shown. +Immediately before each action, revalidation runs again. See +[Approval flow](../../../skills/git-tidy/references/approval-flow.md). + +## Compatibility + +- Existing scopes and `--dry-run` remain valid. +- HIGH/MEDIUM/LOW remain a presentation projection, not the canonical schema. +- `metadata` remains available but cannot claim work-bearing deletion safety. +- Consumers support all `1.x` additive versions they understand and fail + closed on unknown major versions. +- Legacy rows are never allowed to restore age-only stash deletion, + name-only pull request joins, dirty-worktree removal, dead-remote guesses, or + preselected recovery-destroying maintenance. + +## Rollout requirements + +1. Correct unsafe legacy classifications before freezing this contract. +2. Route the skill through the four focused references. +3.

Keep `proof` as the default for work-bearing scopes only while those gates + pass. +5.

Pull request evidence joins by repository identity, exact head ref name, and + exact head OID and is never durable. +4. Every work item has one of seven user-requestable work outcomes; destructive + operations exist only as independently proved per-carrier actions and are + never inferred from `delete`. +5.

Partial, hostile, unsupported, over-budget, or drifted evidence fails + closed. +7. `applyReview` is strict and monotone. +8. Analysis and revalidation do not mutate local Git or GitHub state and never + perform remote refresh. +9. Optional analysis, recovery, each mutation class, and each GitHub write + have separate approvals. +10. Node.js `>=22` is preflighted; missing or older Node limits orchestration to + metadata and suppresses work-bearing destructive offers. +11.

Normal interactive output uses a numbered Git Clean style report with safe, + review, keep, and protected sections.

These records use the same process +boundary, byte limits, stable identities, coverage gaps, and schema validation +as work-bearing evidence: -On Windows, use `Get-ChildItem -Recurse -Filter *.orig` and `Test-Path`. +- `tags`: inventory local tag identity and peeled object evidence; +- `artifacts`: inventory merge backups and interrupted-operation markers; +- `blobs`: inventory bounded large-blob metadata, report-only; and +- `maintenance`: inventory object, pack, garbage, and interrupted-operation + health. -| Condition | Confidence | Label | -|-----------|------------|-------| -| `.orig` files exist | 🟢 HIGH, merge backup artifacts | `artifact-orig` | -| `MERGE_HEAD` / `REBASE_HEAD` exists | 🟡 MEDIUM, interrupted operation (verify first) | `artifact-interrupted` | -| `rebase-merge` / `rebase-apply` directory exists | 🟡 MEDIUM, interrupted rebase (may need `--abort`) | `artifact-rebase` | -| `CHERRY_PICK_HEAD` / `BISECT_LOG` exists | 🟡 MEDIUM, interrupted operation | `artifact-operation` | +For an explicit legacy scope, show that inventory as the primary result. For +`all`, append all four inventories after the content-aware dashboard. Never +convert age, size, names, or interrupted state into cleanup approval. A failed, +truncated, or unavailable collector remains a visible coverage gap. It must not +silently turn into an empty successful result. -### Step 8: Ignored-but-tracked files +### 3.2 Preserve each run artifact -Files matching `.gitignore` that are still tracked (common when ignore rules are -added after the files were committed): +When session artifact storage is available, persist every accepted analyzer +result under a unique immutable name: -```bash -git ls-files --cached --ignored --exclude-standard +```text +git-tidy--.json ``` -| Condition | Confidence | Label | -|-----------|------------|-------| -| File matches `.gitignore` and is tracked | 🟡 MEDIUM, should be untracked (`git rm --cached`) | `tracked-ignored` | - -`git rm --cached ` does not delete the file from disk, but it does create a -commit that removes it from the repo. Warn that collaborators will see the file -deleted on their next pull. - -### Step 9: Large blobs in history +Never overwrite a prior run. If the name already exists, add a monotonically +increasing numeric suffix. A convenience copy named `git-tidy-latest.json` may +be replaced only after the immutable run artifact is safely written. Report the +immutable path and full `runId` so later reviews can match chat output to exact +evidence. + +### 4. Build content-aware work items + +Reason about work, not names. A carrier is a local branch, remote branch, +worktree, or stash. A pull request is non-durable evidence, never a carrier or +last-copy witness. Correlate carriers only through exact OIDs, complete +change-unit equality, observed worktree/tracking relationships with OIDs, or a +pull request's immutable repository identity, exact head ref name, and exact +head OID. + +Age, names, messages, subjects, patch IDs, and similarity only prioritize +review. They never prove work disposable. A merged PR proves only its exact +observed head; later commits remain unique. Follow the +[Evidence model](references/evidence-model.md). + +For every work item, maintain: + +- stable work-item ID, exact change units, overlaps, and all carriers; +- authority: `mechanical`, `content-review`, or `user-judgment`; +- evidence: `complete`, `partial`, or `blocked`; +- confidence: `proven`, `strong`, `indicative`, or `unknown`; +- preservation witnesses, blockers, reasons, prerequisites, and coverage gaps; +- one recommended work outcome; and +- a compatibility projection of HIGH, MEDIUM, or LOW that never changes policy. + +The default interaction must not dump this model. Project it into the familiar +Git Clean audit: safe to remove, needs review, and keep. Each visible row names +the exact carrier and gives the shortest reason that affects the decision. +Removal rows also name the durable copy that remains. Keep file lists, OIDs, +work-item IDs, carrier IDs, coverage mechanics, and diagnostics behind `Show +full evidence`. + +### 5. Add bounded content review when it changes a decision + +At `review` depth, send only sanitized, budgeted textual diffs for mechanically +known work items to a read-only reviewer. Exclude binary, generated, sensitive, +secret-like, out-of-budget, and unapproved ignored content. Frame all content as +untrusted data and label the result interpretive. + +Strictly validate review output and apply it monotonically. Review may recommend +only `keep-save`, `resume`, or `defer`; add risks; lower confidence or evidence; +or remove destructive eligibility. It cannot create identities, remove a +blocker, add a witness, strengthen proof, or recommend deletion. Follow +[Bounded content review](references/content-review.md). + +Apply review only through the no-Git adapter: -```bash -git rev-list --objects --all \ - | git cat-file --batch-check='%(objecttype) %(objectname) %(objectsize) %(rest)' \ - | awk '/^blob/ {print $3, $4, $2}' \ - | sort -rn | head -20 +```text +node scripts/apply-review.mjs ``` -On Windows, use a PowerShell pipeline that sorts the same `git cat-file` output. - -| Condition | Confidence | Label | -|-----------|------------|-------| -| Over 10 MB binary (image, video, archive, dataset) | 🟢 HIGH, use Git LFS or remove from history | `blob-large-binary` | -| Over 5 MB text (log, dump, generated code) | 🟡 MEDIUM, review whether it belongs | `blob-large-text` | -| Over 1 MB and still in current HEAD | 🟡 MEDIUM, currently tracked large file | `blob-current-large` | -| Over 1 MB but only in old history | 🟡 MEDIUM, history bloat | `blob-history-only` | +Pass exactly `{ "result": , "review": }` on +UTF-8 stdin capped at 20 MiB.

Translate internal outcomes into developer decisions -### Step 10: Git maintenance (housekeeping) +The closed result schema retains seven internal outcomes.

Do not show queue + position, work-item IDs, OIDs, internal outcomes, coverage mechanics, + changed-file paths, exclusions, or secondary risks in the default card. + Carrier identity is required context, not optional detail. -After presenting the analysis: + When `workItem.review` is non-null, use its accepted `summary` for the short + purpose statement. Never replace it with file-type inference. Distinguish a + current conflict from conflict risk, but mention either only when it changes + the recommendation. -1. **Ask what to delete** with `ask_user`: - - 🟢 HIGH items may be pre-selected as the default choice. - - 🟡 MEDIUM items are listed but not pre-selected. - - 🔴 LOW items are shown as "recommended to keep"; the user can override. - - Offer "all safe", "all", or pick individually by number. +6. Keep choice labels short and action-oriented. Use at most five: -2. **Show the exact commands** before running them: - ``` - Will execute: - git worktree remove ../wt/add-login - git branch -d feature/add-login - git push origin --delete feature/add-login - git stash drop stash@{2} - git tag -d v0.1.0 - git remote remove old-fork - rm src/utils.js.orig - git rm --cached .env.local - git rerere gc + ```text + Update branch (Recommended) + Open pull request as-is + Show details + Keep for later ``` -3. **Get final confirmation** with `ask_user`: "Proceed with cleanup of N items?" - -4. **Execute in safe order**: - 1. Worktree removals first (they reference branches). - 2. Local branch deletions (`git branch -d`; `-D` only if the user explicitly - approved unmerged loss). - 3. Remote branch deletions (`git push origin --delete `). - 4. Stash drops (`git stash drop stash@{N}`) in reverse index order (highest N - first) so indices do not shift. - 5. Tag deletions (`git tag -d `, then `git push origin --delete - refs/tags/` if also on the remote). - 6. Remote removals (`git remote remove `). - 7. Artifact cleanup (delete `.orig` files; abort interrupted operations only - with explicit confirmation). - 8. Ignored-but-tracked untracking (`git rm --cached `) with a commit. - 9.

Never delete without explicit `ask_user` approval. -2. Never delete the default or currently checked-out branch. -3. Never force-delete (`-D`) without an explicit warning that unmerged work is lost. -4. Prefer `git branch -d` over `git branch -D`. -5. Remote deletions are irreversible; always warn before `git push origin --delete`. -6. Worktree removal with a dirty state needs explicit force confirmation. -7. If more than 20 items are selected, process in batches of 10 with confirmation between batches. -8. All operations are idempotent and safe to re-run if interrupted. -9. Never rewrite history; large-blob findings are report-only. -10. Never remove `origin` or a remote with checked-out branches. -11. Never delete the latest 10 version tags or a tag with a GitHub Release. -12. `git rm --cached` creates a commit; warn that collaborators will see the file removed on next pull. - -## Performance Notes - -- For repos with many branches (over 50), batch `gh pr list` calls to avoid rate limits. -- Use `git branch --merged` as the fast local path first. -- Only call the `gh` API for branches that are not conclusively merged locally. -- Cache PR lookups within a single run to avoid duplicate API calls. - -## Exit Criteria - -- Every selected item is cleaned, or its failure is reported with a reason. -- A summary of actions taken: branches deleted (local/remote), worktrees removed, - stashes dropped, tags deleted, remotes removed, artifacts cleaned, files - untracked, maintenance commands run. -- Protected entities preserved. -- Large-blob findings reported with recommended next steps; no history rewritten. -- No data loss: only confirmed-safe operations executed. + Adapt only the verb when another outcome is relevant. Keep each label under + 45 characters. The question already provides context, so do not repeat the + work summary or branch counts in every choice. + + `Show details` does not record an outcome. It displays the full reviewed + summary, changed-file groups, ahead/behind state, worktree and pull request + state, preservation evidence, blockers, content exclusions, risk flags, and + recommendation rationale. Then ask the same concise decision again. + +7. Record the choice, show the next item, and continue until the user stops or + every presented item has a desired outcome. + +The presence of active or ambiguous work never forces active-work triage during +a cleanup-first run. + +For a dirty linked worktree, lead with `Do not delete yet` and show only the +shortest safe sequence: save the changes, remove the worktree, then reconsider +the branch.

Preserve legacy non-work scopes safely + +- Read every legacy scope from the typed inventory in step 3.1. +- **Tags:** Inventory local identity and peeled object evidence. Keep tags by + default. Tag deletion is separate. +- **Artifacts:** Report `.orig` files and interrupted Git operations. Never + assume a backup is disposable or abort an operation. File removal and each + abort/recovery action are separate. +- **Ignored-but-tracked:** List without reading ignored content by default. + `git rm --cached` is a separately approved repository change with collaborator + impact. +- **Large blobs:** Report only. Never rewrite history, run filter tools, download + LFS payloads, or force push. +- **Remotes:** A network, auth, DNS, timeout, rate-limit, or access failure means + unknown, not dead. Never remove `origin` or a remote used by checked-out work. + GitHub branches attach only by exact repository ID, ref name, and tip OID. + Protected branches block deletion. Remote-only missing content remains + partial, `keep`, ineligible, and `defer` until a separately approved isolated + acquisition satisfies its deterministic prerequisite. +- **Maintenance:** Inventory object and recovery health read-only. Reflog expiry, + GC, and repack can destroy recovery paths. Never call them non-destructive, + preselect them, or bundle them with cleanup. + +Dirty, conflicted, locked, missing, or unknown worktree state takes precedence +over age, merge, PR, and orphan hints. It blocks normal removal until its overlay +is separately saved and verified or the user explicitly approves discard. +The main worktree is always protected and blocked by `worktree-main`. Report +staged, unstaged, conflict, submodule, intent-to-add, and untracked counts plus +nullable sparse state and ignored-path count. Count ignored paths only from +`! ` records returned by `--ignored=matching --untracked-files=all`; never +retain their names or read their payloads. + +### 8. Expose coverage gaps + +Report every omitted, failed, unsupported, truncated, over-budget, hostile, or +unavailable evidence source with affected work-item IDs. Remote uncertainty, +missing objects, skipped content, runtime failure, and incomplete comparisons +block destructive carrier actions. Never convert absence of evidence into a +clean or dead assessment. + +### 9. Approve, revalidate, and hand off + +A selected outcome isn't authorization. Run read-only `revalidate` on the +selected carriers and witnesses to obtain the inert guarded action plan. Any +drift emits no plan and returns to fresh analysis. For each action class in a +stable plan, show exact argv, refs or paths, expected OIDs, selected carriers, +retained witnesses, prerequisites, order, effects, recovery limits, and +approval class. Obtain strict approval for that class only. Immediately +revalidate again, then hand only identical stable plan steps to the established +workflow. Do not combine refresh, optional reads, temporary creation, temporary +cleanup, save/recovery, checkout, rebase, merge, push, PR creation, PR merge, or +any cleanup class in one consent. PR creation and merge use their established +GitHub-write flows; a merge always needs fresh per-PR approval. Follow +[Approval and revalidation flow](references/approval-flow.md). + +A save counts only after exact comparison proves the new durable carrier holds +the change units. Approval for recovery never implies cleanup. If a batch partly +fails, stop, re-inventory, recompute witnesses, and seek new approvals. + +## Output + +For normal interactive runs, render the Git Clean style categorized report +before the selection prompt. Number every visible item and show safe removals, +items needing review, items to keep, and protected entities. Every safe row +names both the exact target and the durable copy that remains.

The `--batch-check` format is +one argv element even though it contains spaces; supply validated OIDs on stdin +and parse one bounded ASCII line per OID. + +Resolve the default branch only from the locally observed symbolic ref +`refs/remotes/origin/HEAD`. Its LF-terminated target must be valid UTF-8, begin +with `refs/remotes/origin/`, identify a branch other than `HEAD`, and exactly +match an inventoried remote ref object. Map only that suffix to +`refs/heads/` for local default-branch protection, and use the inventoried +remote target OID as the comparison base. Never fall back to `main`, `master`, +another remote, an arbitrary local branch, or display text. + +Missing, malformed, non-origin, non-UTF-8, or dangling default identity records +the `default-branch-identity` coverage gap. Every ordinary local branch then has +unknown, partial protection and blocker `default-branch-identity-unknown`. +Explicit policy-protected local refs remain protected with complete policy +evidence but still receive that blocker. No affected local branch can receive a +destructive action. + +For each local branch or locally available remote ref, store +`observed.ancestry={mergeBaseOid,ahead,behind,state,mergedIntoDefault,reachableFromDefault}`. +The `rev-list` left count is behind and the right count is ahead.

Do not follow a path +from repository content. Parse staged, unstaged, untracked, conflicted, +intent-to-add, submodule, branch, detached, and unborn state separately. +Derive a status fingerprint and categorical counts from raw records. + +For ignored counting, the exact supported recipe uses both +`--ignored=matching` and `--untracked-files=all`. Git rejects the combination +with `--untracked-files=no`. Count only NUL-framed records beginning with `! `; +do not retain ignored names or read or hash their payloads. A positive count on +a linked worktree adds `ignored-content-present`; an unavailable count adds +`ignored-state-unknown` and its matching gap. + +Read sparse enablement, cone mode, and sparse-index mode as strict local +Booleans. Count LF-framed `sparse-checkout list` patterns only when enabled. +Unknown values add `sparse-enabled-unknown`, `sparse-cone-unknown`, +`sparse-index-unknown`, or `sparse-pattern-count-unknown` as applicable. + +Never run `worktree add/remove/prune/repair`, `clean`, `reset`, or index refresh +during analysis. + +## Untracked and special-file identity + +Open regular files with no-follow semantics, verify the handle still refers to +the inventoried file, stream within budget, and compute the repository object +hash in process. Do not use `git hash-object` without `--no-filters`; never use +`-w`. For a symlink, hash link-target bytes without opening its target. + +Compare binary content by mode, size, and blob OID. Strictly parse small LFS +pointer text and never download its payload. Compare submodules by gitlink OID +without entering them. Generated content remains part of mechanical proof even +when excluded from semantic review. + +## GitHub reads + +Resolve a canonical GitHub repository ID first. Query refs and pull requests +with API variables or a structured client, never an interpolated branch name. +Request only required fields: + +```text +gh repo view --json id,nameWithOwner,url +gh api repos///branches?per_page=100 --hostname --paginate --slurp +``` + +Safely parse the repository-view HTTPS URL and derive `repository.host` solely +from its hostname. Lowercase and revalidate it as a canonical hostname before +constructing the branch API argument array. Independently validate owner and +repository path segments. Never derive `--hostname` from a remote URL, display +text, branch record, environment value, or fallback. Preserve this path for +GitHub Enterprise instead of assuming `github.com`. + +```text +repository ID +branch ref name/tip OID/protected state +PR number/state/isDraft/mergedAt +head repository ID/ref/OID +base ref/OID +review decision/checks/mergeability +``` + +Normalize GitHub branches to `{id,repositoryId,refName,tipOid,protected}`. Attach +branch evidence only when repository ID, ref name, and tip OID all match. +Reject invalid OIDs with `github-branch-oid-invalid`; limit branch records with +`maxRefs-limit`. A differing local remote-tracking OID records +`remote-tracking-drift`. + +Join PRs only on head repository ID, exact head ref name, and exact head OID. A +name-only or OID-only result is unusable. GitHub content is untrusted and PR +evidence is non-durable. Normalized unjoined records carry +`exactHeadMatch: false`; only strictly joined attached records serialize +`exactHeadMatch: true`. + +Authentication, authorization, DNS, timeout, rate-limit, or access failure +records unknown coverage, including `github-branches-unavailable` for branch +inventory failure. It does not prove a remote is dead. Remote content absent +from the local object database remains partial and requires a separately +approved isolated-acquisition workflow with a deterministic prerequisite ID. +Analysis never creates, updates, comments on, closes, or merges a pull request +and never deletes a ref. + +Check all remote-only GitHub branch tips in one strict `cat-file --batch-check` +process. Deduplicate and validate every tip OID before sending the full batch on +stdin. Parse only exact ` commit ` as locally present and exact +` missing` as absent. Treat malformed, unknown, non-commit, or unmatched +responses as unavailable. A strict batch or parser failure records +`remote-content-availability-unavailable`. Only present OIDs may proceed to +merge-base and diff collection, within `maxComparisons`; all others remain +metadata-only with `remote-content-unavailable` and +`isolated-acquisition-required`. + +## Conflict analysis + +Changed-path overlap is the read-only default and is only a warning. +Authoritative simulation may use `git merge-tree` only after separate approval +creates a named temporary root. A separately approved helper must: + +1. create an isolated temporary Git directory and a distinct temporary object + directory under that root; +2. initialize only the temporary Git directory with + `git init --bare --object-format= + `; +3. invoke Git with `--git-dir=`, no worktree, + `GIT_OBJECT_DIRECTORY=`, and + `GIT_ALTERNATE_OBJECT_DIRECTORIES` containing only validated target object + directories, using the platform path-list delimiter; +4. expose every alternate read-only, keep all writable paths and Git config + inside the temporary root, and run + `git merge-tree --write-tree --messages -z + --merge-base= + `; and +5. verify the target repository's refs, index, worktrees, config, object IDs, + and object count are unchanged. + +The analyzer itself never initializes directories or runs a fetch. It may +consume the separately approved helper's bounded result. Record exit status and +conflicted-path records; do not count conflict markers. + +Temporary directory creation and deletion are separate approvals. Unsupported +`merge-tree` capability, object-format mismatch, writable alternate, inherited +target Git directory/config, or inability to guarantee both isolated +directories degrades to overlap plus `defer`, not a weaker simulation. A clean +result proves mechanical mergeability only. + +## `revalidate` + +The analyzer's `revalidate` operation receives the exact stdin object defined +in [Analyzer invocation](#analyzer-invocation).

Destructive operations exist only as +explicit per-carrier actions and are never inferred from a recommendation. + +| Recommendation | Typical carrier actions | +|---|---| +| `delete` | Work outcome only: retained canonical carrier is `keep`; a separately proved duplicate may receive `delete-ref`, `drop-stash`, or `remove-worktree` | +| `keep-save` | Durable carrier: `keep`; unsaved carrier: `keep` with save prerequisite | +| `resume` | Chosen carrier: `keep`; duplicates normally `no-action` pending user decision | +| `update-rebase` | Source carrier: `keep`; hand off, no destructive action | +| `merge-as-is` | Source carrier: `keep`; hand off, no destructive action | +| `open-pr` | Source carrier: `keep`; hand off, no destructive action | +| `defer` | Every carrier: `keep` or `no-action` | + +`delete` requires `mechanical`, `complete`, `proven`, no blocker, protection +clear, exact witnesses, and current identities. Recommendation alone never +authorizes or implies an action. Each destructive carrier action requires its +own identity, proof, witness set, blocker check, and approval. + +## Source-specific proof + +### Stashes + +The stash graph, not its message, is authoritative: + +1. first parent: original `HEAD` and base; +2. second parent: index snapshot; +3. stash commit tree: final tracked worktree snapshot; and +4. optional third parent: untracked/ignored snapshot. + +Analyze base-to-index, index-to-stash-tree, base-to-stash-tree, and third-parent +content independently. Missing or malformed topology is incomplete and +`defer`. Record exact identity as +`{stashOid,baseOid,indexOid,treeOid,untrackedOid,observedSelector}`. Resolve +`treeOid` from Git's tree-peeling revision operator for valid topology. Base, +index, tree, and +untracked OIDs remain null when unavailable; `untrackedOid` is also null for a +valid two-parent stash. Use first-parent containment to find viable resume +bases. Stable patch IDs and `git cherry` corroborate only. + +Record `observed.componentChangeUnitIds` as the closed map +`{staged,unstaged,trackedFinal,untracked}`. `staged` is base-to-index, +`unstaged` is index-to-stash-tree, `trackedFinal` is base-to-stash-tree, and +`untracked` is third-parent evidence. Retention `changeUnitIds` remains staged +plus unstaged plus untracked only, preserving distinct snapshots and staged-only +duplicate behavior. Associate every `trackedFinal` ID with the stash work item +for reporting and review. + +Before a drop, remap the displayed selector to its recorded stash OID. Drop +multiple approved stashes in descending index order and remap before each. + +### Local branches + +Record tip/tree OIDs, upstream, ahead/behind, checked-out worktrees, ancestry +against the observed default tip, exact changed-path end states, and associated +PR identity. Every local branch and locally available remote ref stores +`observed.ancestry={mergeBaseOid,ahead,behind,state,mergedIntoDefault,reachableFromDefault}`. +State is exactly `identical`, `ahead`, `behind`, or `diverged`. + +Resolve the default branch exclusively from the locally observed +`refs/remotes/origin/HEAD` symbolic ref and its exact inventoried +`refs/remotes/origin/` target object. Map the suffix to +`refs/heads/` only for local default protection, and use the remote target +OID as the comparison base. There is no `main`, `master`, other-remote, or +arbitrary-branch fallback. + +If that identity is missing, malformed, non-origin, non-UTF-8, or dangling, +record `default-branch-identity`. Ordinary local branches then have unknown +protection, partial protection evidence, and +`default-branch-identity-unknown`. Policy-protected local refs remain protected +with complete policy evidence but retain the blocker. Destructive branch +actions remain unavailable. + +Resolve the merge base exactly, then count +`git rev-list --left-right --count ...`, interpreting left as +`behind` and right as `ahead`. Diff only merge base to tip. An ahead count of +zero has no unique work and emits an empty unit set. Record +`branch-no-unique-work` in that case plus exactly one of `branch-identical`, +`branch-ahead`, `branch-behind`, or `branch-diverged`. + +Merge-base, count, diff, and comparison-limit failures record respectively +`branch-merge-base-unavailable`, `branch-ancestry-unavailable`, +`branch-change-units-unavailable`, or `branch-proof-limit`. Each also adds +`branch-proof-incomplete`; incomplete branch proof cannot authorize destruction. + +A merged PR proves only its exact head. If the live tip differs, its added +range remains active. Squash/cherry-pick proof may combine stable patch IDs, +`git cherry`, and complete end-state blob/mode equality, but only exact +end-state equality is preservation proof. Reverts, unique merges, replacement +refs, grafts, shallow/partial history, unrelated histories, and missing +objects block a proven verdict unless another exact proof is complete. + +### Remote branches and pull requests + +The analyzer never refreshes, fetches, or prunes. Identify a GitHub repository +by immutable repository ID. Normalize each GitHub branch to stable ID, +repository ID, ref name, tip OID, and protected state. Attach it to remote +evidence only on exact repository ID, ref name, and tip OID. + +Derive the GitHub API hostname only from the safely parsed HTTPS URL returned by +the closed repository-view response. Lowercase and canonically revalidate that +hostname before passing it as the separate `--hostname` argument. This supports +GitHub Enterprise without trusting remote URLs or repository display text. + +Join a PR using its head repository ID, exact head ref name, and exact head OID. +Record open, draft, closed-unmerged, merged, review, check, +mergeability, and post-merge-advanced states separately. A separately approved +external refresh invalidates prior observations and requires a new analyzer +run. + +Normalized unjoined PR records carry `exactHeadMatch: false`. Only a strict +repository ID, ref name, and head OID match may attach, and serialized attached +PR evidence carries `exactHeadMatch: true`. + +PR data is non-durable. A PR can corroborate shipped identity but cannot be a +last-copy witness. Same-name fork heads never share evidence. + +Use locally available remote-tracking objects without network writes. +Determine remote-only GitHub tip availability with one strict batched +`cat-file --batch-check` read across all deduplicated validated OIDs. Exact +` commit ` is present; exact ` missing` is absent. Unknown, +malformed, non-commit, or unmatched output is unavailable. Strict batch or +parser failure records `remote-content-availability-unavailable`. Only present +tips proceed to merge-base and diff proof within `maxComparisons`. + +Remote-only unavailable content remains metadata-only and incomplete unless the user separately +approves an external isolated-acquisition workflow and then starts a new +analyzer run. It remains `keep`, ineligible, and `defer`, with +`remote-content-unavailable`, `isolated-acquisition-required`, and one +deterministic prerequisite ID. Protected GitHub branches add +`remote-branch-protected`. Local tracking OID disagreement adds +`remote-tracking-drift`. Authentication, authorization, DNS, timeout, +rate-limit, or access failure means unknown, not dead or redundant, and records +`github-branches-unavailable` when branch inventory fails. + +### Worktrees + +Analyze the main and every linked worktree with porcelain-v2 NUL output. +Record staged, unstaged, intent-to-add, untracked, conflicted, detached, +unborn, locked, prunable, missing, sparse, invalid-common-directory, submodule, +file-mode, branch OID, and status fingerprint state. Record nonnegative staged, +unstaged, submodule, conflict, intent-to-add, and untracked counts. Record +sparse enablement, cone mode, sparse-index mode, and pattern count as values or +null with an explicit gap. + +Count ignored paths only from `! ` records produced by the exact +`--ignored=matching --untracked-files=all` status recipe. Do not retain ignored +names or read payloads. A positive count on a linked worktree adds +`ignored-content-present`; an unavailable count adds `ignored-state-unknown` +and blocks removal. + +The main worktree always has `protection: "protected"`, complete protection +evidence, and blocker `worktree-main`. Conflicts, dirty submodules, and +intent-to-add add `worktree-conflict`, `worktree-submodule-dirty`, and +`worktree-intent-to-add` respectively. + +Dirty, locked, conflicted, or unknown worktrees are never normal removal +candidates. Their overlay must be separately saved or explicitly discarded +through an approved workflow before removal can be reconsidered. + +### Special files + +- Binary: compare mode, size, and blob OID; never semantically review payload. +- Git LFS: parse only a strict small pointer; compare declared OID and size; + never download payload. +- Submodule: compare gitlink OID; do not recurse. +- Symlink: compare mode and link blob OID; do not follow. +- Generated: include mechanically, omit from semantic review, never presume + disposable. +- Rename/copy: normalize path/content operations and retain display metadata. + +## Confidence projection + +HIGH is only complete, blocker-free, proven mechanical evidence. MEDIUM is +strong mechanical evidence or complete user-judgment evidence. LOW includes +content review, partial evidence, conflict, or preservation uncertainty. The +projection is display compatibility only and cannot change eligibility. + +Node.js below version 22, a missing runtime, or an invalid runtime probe is a +capability blocker. Orchestration may report metadata, but it cannot produce +proof/review evidence or offer a destructive action for a work-bearing carrier. diff --git a/skills/git-tidy/scripts/apply-review.mjs b/skills/git-tidy/scripts/apply-review.mjs new file mode 100755 index 0000000..c2a2bbe --- /dev/null +++ b/skills/git-tidy/scripts/apply-review.mjs @@ -0,0 +1,100 @@ +#!/usr/bin/env node +import { fileURLToPath } from "node:url"; +import path from "node:path"; + +import { + applyReview, + validateMechanicalResult, +} from "./lib/review-policy.mjs"; + +export const MAX_INPUT_BYTES = 20 * 1024 * 1024; +const MAX_ERROR_CHARACTERS = 500; + +function exactKeys(value, keys) { + return value !== null && + typeof value === "object" && + !Array.isArray(value) && + Object.keys(value).sort().join("\0") === [...keys].sort().join("\0"); +} + +export function applyReviewPayload(payload) { + if (!exactKeys(payload, ["result", "review"])) { + throw new TypeError( + "stdin must contain exactly result and review", + ); + } + const validation = validateMechanicalResult(payload.result); + if (!validation.valid) { + return { + accepted: false, + result: structuredClone(payload.result), + diagnostics: validation.diagnostics, + }; + } + return applyReview(payload.result, payload.review); +} + +export async function readBoundedJson( + stream, + maxBytes = MAX_INPUT_BYTES, +) { + if ( + !stream || + typeof stream[Symbol.asyncIterator] !== "function" + ) { + throw new TypeError("stdin must be an async byte stream"); + } + if (!Number.isSafeInteger(maxBytes) || maxBytes < 0) { + throw new RangeError("input limit must be a nonnegative safe integer"); + } + + const chunks = []; + let size = 0; + for await (const chunk of stream) { + const bytes = Buffer.from(chunk); + size += bytes.length; + if (size > maxBytes) { + throw new RangeError("stdin exceeds the 20 MiB limit"); + } + chunks.push(bytes); + } + if (size === 0) { + throw new TypeError("apply-review requires JSON stdin"); + } + + const text = new TextDecoder("utf-8", { fatal: true }) + .decode(Buffer.concat(chunks)); + return JSON.parse(text); +} + +export async function main({ + input = process.stdin, + output = process.stdout, +} = {}) { + const payload = await readBoundedJson(input); + const applied = applyReviewPayload(payload); + output.write(`${JSON.stringify(applied)}\n`); + return applied; +} + +function sanitizeError(error) { + return String(error?.message ??
