Leave the base blank to detect the local + `origin/HEAD`, `origin/main`, `origin/master`, `main`, or `master`.

Accepting a +real source immediately opens the dedicated Replay panel, displays the selected +PR or branch and exact scratch path, and shows an animated checkout status until +the original review is ready.

Original branches are never checked out, modified, reset, +committed, or pushed. + +Returning to the same pull request safely resumes its existing scratch worktree +only when its exact path, shared repository, local branch, original merge-base +commit, and clean working tree are independently verified. The review picker +also recognizes GitHub scratch worktrees created before source-linked recovery +metadata existed. Reopening an existing review never creates a replacement +branch, overwrites saved reviewer changes, or adopts an unrelated directory. + +If a previous checkout was interrupted after creating the Replay branch, Red +can also restore its missing scratch worktree.

No GitHub fetch or branch operation + occurs. +- **Start review over…**, also available as `D`, `Space R D`, or + `:ReplayRestart`, first previews the exact local progress, notes, drafts, and + unsaved scratch buffers that will be discarded. Only after explicit + confirmation does Red remove and recreate the independently verified + Replay-owned scratch worktree at the original merge base and open a new review + session. The original PR branch, separately authorized author worktree, and + comments already published to GitHub remain untouched. Previously discarded + review generations cannot reappear through older editor snapshots. + +If a previously approved GitHub submission has an uncertain provider result, +resolve that submission before restarting its local review. + +Replay initially places its dedicated coach panel on the left and the editable +scratch source on the right, matching the pull-request replay mockup. The +coach is rendered by Red's panel system; it is not a Markdown file, a scratch +document, or an editable editor split. It contains the verified source, original +author and branch, the actual unified diff for each individual step, the +reconstruction task, optional hints, and progress. + +The panel also shows the original pull-request title. Real learning-step titles +and reconstruction tasks identify the changed source symbol rather than exposing +Git's raw hunk heading. Explanations prefer the author's documentation on the +exact changed source, then the matching author-written pull-request change, and +finally the pull request's actual motivation. Markdown headings are never +presented as explanations. This guidance is derived from the pinned original +source and review context; it does not invent or attribute undocumented intent +to the author. + +For a multi-file review, `j` and `k` or the down and up arrows select the next +and previous original hunk, while `[` and `]` jump directly to the first hunk +in the previous or next changed file. The left and right arrows or `h` and `l` +also move between changed files. Both motions switch the existing editor window +to the actual scratch file. The compact pinned list shows real completion: +`○` is pending, `✓` was reconstructed by hand, `⊕` was automatically applied, +and `✎` has a private note. The selected original-change title is displayed +separately in full; long source paths preserve their actual filename. +The source cursor and viewport jump directly to the original hunk, even when +the change occurs thousands of lines into a large file. +Changes from different files stay in their own buffers; no unrelated file tree, +editable guide, or extra pane is created. + +The coach is a structured editor surface, not a rendered Markdown document. By +default the guide and editable source split the terminal approximately 50/50; +the extra column goes to the source, and the guide stops growing at 100 columns. +The default follows terminal resizing until the reviewer explicitly adjusts the +divider and preserves enough space +for the editable source. PR context and a compact, vertically navigable change +list stay pinned above the current author's rationale. At normal terminal +heights, a blank line separates the identity, changes, and rationale; the changes +heading uses a quiet horizontal rule. Shorter terminals reclaim the spacing +before sacrificing any pinned changes or source lines. The rationale and hint +share one fixed-size region; press `Enter` to expand the full explanation or +hint without moving the change list. Notices and errors have their own reserved +status row. Only the exact original hunk grows or scrolls. A compact, theme-colored +action bar stays pinned at the bottom. Source retains its original line numbers, +language-aware Tree-sitter highlighting, and the active theme's addition, +removal, and modification colors. Git transport headers are hidden from the +visual presentation without changing the complete patch used for validation and +application. Source lines are clipped rather than wrapped, preserving +indentation; a visible `›` marks code that extends beyond a narrow pane. + +Focus the coach and use the existing Vim edge-movement commands to move the +panel itself: + +- `Ctrl-w H`: Dock the focused panel on the left. +- `Ctrl-w J`: Dock the focused panel at the bottom. +- `Ctrl-w K`: Dock the focused panel at the top. +- `Ctrl-w L`: Dock the focused panel on the right. + +Lowercase `Ctrl-w h/j/k/l` continues to move focus without changing split +topology. `Ctrl-w w` cycles between the coach and source. A focused guide shows +`▌ PR REPLAY`, a theme-accented `┃` or `━` at its docking edge, and a `▶` +beside the current step. The real terminal cursor rests on that marker and the +status line reads `REPLAY`. Focusing the source restores the normal editor +status line; the guide, its original diff, and syntax highlighting remain +visible. + +The guide also inherits Red's generic pane resizing. Use `Ctrl-w >` and +`Ctrl-w <` to grow or shrink a left or right Replay pane; use `Ctrl-w +` and +`Ctrl-w -` when the pane is docked above or below the source. Prefix either +binding with a count, such as `5 Ctrl-w >`, for a larger adjustment. +`Ctrl-w =` restores the pane's original size. You can also drag its dividing +line with the mouse; the captured divider brightens immediately and returns to +its normal focus appearance when released. + +Press `z` while the guide is focused to enlarge the original change temporarily. +From either the guide or the editable scratch source, `Space R z` enlarges the +currently focused surface. Repeat the same shortcut to restore the exact +previous split, including a divider width you chose yourself. Zoom never +changes the default 50/50 layout, creates an editor split, alters scratch code, +or modifies the pull request. + +Real review progress is included in Red's crash-safe editor session. Restart +Red with `--resume` to reopen the verified scratch buffers, original source +guide, selected change, completed hunks, private observations, learning mode, +and attributed Replay undo history. Resume does not create or overwrite a +worktree, save the scratch files, or reuse an automatic-application token. If +the pinned source, hunk, worktree, or undo attribution cannot be verified, Red +recovers the normal editor buffers and refuses only the unsafe Replay session. + +## Review role and local outbox + +For a GitHub pull request, the guide verifies the authenticated GitHub viewer +against the original pull-request author, repository, head branch, and exact +head commit. The header then shows one honest role: + +- `YOUR PR`: you are the verified original PR author. You can draft inline + comments, PR-level summaries, and proposed fixes to your own PR. +- `REVIEW`: you are reviewing another user's PR, or ownership could not be + verified. You can draft inline comments and PR-level summaries; proposing a + code change to someone else's PR is refused. + +Write access to a shared repository is not proof that you own a PR. The guide +also shows the original head branch and seven-character commit prefix. Replay +uses the complete immutable commit internally; the short prefix is only for +display. Reopening a review saved before role detection refreshes only the +authenticated GitHub identity in a bounded background worker; it refuses a +moved PR head and never creates another scratch worktree. + +Press `c` in the focused guide to compose a multiline inline comment about the +current original change, or `s` to compose a PR-level summary. Authors can also +press `F` to record a proposed fix. In the composer, `Enter` inserts a new line +and `Ctrl-Enter` saves the complete draft locally. The selected original diff +determines each +inline comment's path, head commit, exact changed-line range, and GitHub `LEFT` +or `RIGHT` side. Scratch-buffer cursor positions and later edits never replace +those coordinates. An `F` proposed fix remains local text: recording it does not +edit either the original PR or its learning scratch source. Opening the real +original PR code is a distinct, explicitly confirmed author action. + +### Open your original pull request code + +When you are both the verified original GitHub PR author and have confirmed +write access to the exact head repository, press `W` in the focused guide or +outbox, or use `Space R W`. Red first produces a read-only preview of the +complete original PR head, exact head repository and branch, authenticated +author, separate local author branch, and durable sibling-worktree path. +Reviewers cannot open an author's original worktree just because they have +write access to a shared base repository. + +Explicitly accepting **Create original PR worktree?** creates a normal Git +worktree at the original PR **head**, not the merge base used for learning. +The local branch is named `replay/author/pr--` and its durable +sibling is named `.replay-author-pr--`. This means +the actual original PR branch can remain checked out elsewhere. For fork PRs, +the preview preserves the exact author-owned fork and original remote branch; +it never substitutes the base repository's `origin`. + +The selected original source file opens as a real, editable Red buffer. The +Replay pane displays **YOUR PR · PR HEAD** so it cannot be mistaken for a +merge-base learning source. The editor can open and edit any real file in the +author worktree through its normal buffer lifecycle; the existing learning +scratch, progress, private review, and original checkout remain untouched. + +Pressing `W` again previews and safely reopens the exact same worktree. Unlike +the learning scratch, the author worktree may contain unsaved work, saved +changes, untracked files, or new local commits descending from the pinned PR +head; Replay preserves all of them. It refuses symlinked paths, a different +repository, an unrelated local branch, or a head that does not descend from the +exact original PR commit. Confirmation is bound to the full original head, +fork, local branch, and path. Before creating or reopening a worktree, a +background worker verifies the authenticated GitHub author and pinned PR head +again. + +Opening original PR code does **not** save a buffer, stage files, commit, +push, submit a review, or start Codex. Normal Git hooks remain active. Agent +execution and committing or pushing back to the exact fork and PR branch will +each require their own separate, explicit user approvals in a later milestone. + +### Ask Codex about an original change + +Press `x` in the focused Replay guide, use `Space R x`, or run `:ReplayAsk` to +open a dedicated Codex companion below the original Replay guide and genuine +source editor. Its inline composer is focused immediately; no question dialog +replaces the source you are reviewing. Press `Enter` to submit, `Shift+Enter` +or `Ctrl+j` for a newline, and `Ctrl+p` / `Ctrl+n` for prompt history. + +The selected original change and source remain visible while the answer +streams. The first `Esc` changes the companion from its composer to transcript +navigation, where `j` / `k` scroll only the conversation. A second `Esc` +restores the exact Replay pane or source editor that opened Codex. Press `q` +from the companion's navigation mode to hide it without losing the +conversation, or `Ctrl-c` to cancel an active request. + +An answer is not automatically recorded as a finding, review comment, or +source edit. From companion navigation, press `f` to explicitly save the +latest answer as a private finding, `c` to prepare an editable original-source +inline comment, or `s` to prepare a PR-level summary. Only explicitly +submitting a draft composer adds an agent-originated draft to the local outbox; +nothing is posted to GitHub. + +Press `X` or use `Space R X` to choose a broader or different request: + +- Ask about the current original change. +- Ask about the complete pinned pull request. +- Explicitly request an inline review-comment suggestion. +- Explicitly request a PR-level review-summary suggestion. +- If you are the verified original author and have opened your original PR + worktree, request inspectable repository-wide source proposals. + +Read-only questions and review suggestions cannot mutate source. Original-PR +source proposals remain staged until you explicitly accept their hunks through +Red's existing agent-review surface. The companion uses a Replay-owned Codex +session and never replaces or captures an unrelated general Agent conversation. +See the [Codex collaboration specification](pr-replay/codex-collaboration.md) +for the underlying authority and review boundaries. + +Press `r` to open the review outbox. It shows the verified role, original +branch and commit, source-linked comments, author fix proposals, PR summaries, +and whether each outcome is `LOCAL` or already `POSTED`. Until you explicitly +approve a GitHub submission, its status reads `nothing sent to GitHub`. Use `h` +and `l` to select drafts, `e` to edit a local draft, and `d` to discard one +after a local confirmation. Posted review comments are read-only and cannot +be silently discarded or submitted twice. Press `r` again to return to the +original guide. + +Every local draft and verified GitHub receipt is part of the crash-safe editor +session and survives `--resume`. The outbox is the same structured, dedicated +Replay pane as the source guide; it preserves the focused `▌ PR REPLAY` title, +highlighted divider, `REPLAY` status, real selected draft cursor, scrollable +content, and pinned review action bar. At the default 46-column width, the +relevant `P` publish, `S` save, and `r` return actions remain visible. + +### Save or move a private review + +Use `S` in the focused outbox or `Space R S` to save comments, PR-level +summaries, local observations, author fix proposals, and verified submission +receipts into a private portable review file. Red suggests a path inside the +repository's shared `.git/red/replay-reviews/` metadata, so saving never dirties +the scratch worktree or original repository. You can choose a different private +location explicitly. + +Use `L` or `Space R L` to load a review on the same or another computer. Red +first checks the exact original host, repository, PR, base, head commit, and +complete diff. It previews the new drafts, observations, and receipts, requires +confirmation before merging, and refuses conflicting text or a file that changes +after the preview. Existing version-one private review files remain readable. +Neither saving nor loading sends anything to GitHub. Imported submission receipts +are deliberately marked **unverified** on the new computer: a local JSON file +cannot prove that GitHub actually accepted a review. Their associated comments +remain editable local drafts until you explicitly press `P` to verify the +original review against GitHub. A forged or stale imported receipt never labels +a draft `POSTED` or silently prevents a legitimate new review. + +### Publish an explicitly approved GitHub review + +For a verified GitHub pull request, add at least one local inline comment or +PR-level summary. Press `P` in the outbox or `Space R P` to choose: + +- **Comment only:** submit feedback without changing the PR's approval state. +- **Approve:** approve another author's exact original PR head. +- **Request changes:** request changes to another author's PR. Add a PR-level + summary with `s` so the author receives a clear explanation. + +The original PR author can choose **Comment only**; self-approval and requesting +changes on your own PR are not offered. Author `F` fix proposals always stay +local and are never inserted into a review comment. Local branch reviews and +the demo cannot publish to GitHub. + +Selecting an outcome does not post anything. Red first shows a +`NOTHING POSTED YET` confirmation containing the exact original repository, +PR number, full pinned head, authenticated GitHub viewer, selected outcome, +PR-level body, and every included human- or agent-proposed inline comment. It +also identifies any original-PR fix proposals that will stay local. Cancel +preserves all drafts. Only explicitly accepting this confirmation starts the +background GitHub request. + +Before that worker can start, Red synchronously writes the exact approved PR, +viewer, commit, outcome, drafts, and request digest into its crash-safe editor +session. If durable session recovery is unavailable or that write fails, no +review is posted. Git and GitHub operations have bounded execution deadlines, +bounded output, noninteractive credentials, and redacted diagnostics. + +Immediately before publication, Red verifies the original PR head and viewer +again. It sends all selected comments and the chosen outcome in one atomic, +event-bearing GitHub review request; it never creates a remote `PENDING` +review. If the head, reviewer, original diff anchor, or previewed draft changes, +submission fails without claiming success. On a verified response, Red marks +the exact submitted drafts `POSTED` and retains their portable GitHub review +receipt. Private notes, the scratch worktree, and the original PR branch are +never modified by review publication. + +If a crash, network failure, or lost response happens after the review request +may have reached GitHub, Red restores the exact request as **uncertain** instead +of allowing a blind retry. Press `P` and confirm a read-only provider lookup. +Red verifies the original repository, pull request, authenticated reviewer, +pinned commit, chosen outcome, review body, and every inline comment and source +coordinate. Exactly one matching review becomes a verified local receipt without +posting again. Only after GitHub confirms that no matching review exists does a +fresh submission become available. Ambiguous or failed lookups remain blocked +and explain why. + +## Key bindings + +All replay bindings use `Space R`; the existing `Space r` rename binding is +unchanged. + +| Keys | Action | +| --- | --- | +| `Space R ?` | Open the Replay keyboard-help popup. | +| `Space R g` | Reopen the current review or choose among existing reviews. | +| `Space R A` | Open the current review's regeneration and restart actions. | +| `Space R R` | Regenerate presentation without changing scratch work or progress. | +| `Space R D` | Preview and explicitly confirm starting the review over. | +| `Space R [` | Jump to the first change in the previous file. | +| `Space R ]` | Jump to the first change in the next file. | +| `Space R n` | Next reconstruction step. | +| `Space R p` | Previous reconstruction step. | +| `Space R h` | Reveal or hide the current hint. | +| `Space R m` | Switch between Challenge and Snippet mode. | +| `Space R i` | Focus the editable scratch source for manual reconstruction. | +| `Space R v` | Validate the real scratch source against the original hunk. | +| `Space R a` | Immediately apply one exact, undoable original hunk. | +| `Space R u` | Safely undo the most recent Replay-authored scratch hunk. | +| `Space R o` | Add a private, recoverable source-linked observation. | +| `Space R f` | Show local reviewer observations. | +| `Space R c` | Draft an exact original-source inline review comment. | +| `Space R x` | Ask Codex a direct question about the current original change. | +| `Space R X` | Choose a Codex question, review-draft, or authorized source-fix scope. | +| `Space R F` | Draft a proposed fix for your verified original PR. | +| `Space R W` | Preview and explicitly open your original PR-head author worktree. | +| `Space R r` | Show the local review outbox or return to the guide. | +| `Space R s` | Draft a pull-request-level review summary. | +| `Space R e` | Edit the selected local review draft. | +| `Space R d` | Discard the selected local review draft after confirmation. | +| `Space R P` | Preview and explicitly confirm publishing a GitHub PR review. | +| `Space R S` | Save a private portable review, observations, and submission receipts. | +| `Space R L` | Preview and load a source-verified portable private review. | +| `Space R q` | Hide the coach without touching the scratch source or progress. | + +While the dedicated coach is focused, `j` and `k` or the down and up arrows +select the next and previous reconstruction steps. `n` and `N` jump to the next +and previous genuinely unreviewed changes. `J` and `K` scroll the original hunk +one line, `Ctrl-d` and `Ctrl-u` scroll it half a page, and +`Ctrl-f`, `Ctrl-b`, Page Down, and Page Up scroll it a full page. The mouse wheel +also scrolls the hunk without changing the selected step. `[` and `]` jump +between changed files, as do the left and right arrows or `h` and `l`. `H` and +`L`, or Shift-Left and Shift-Right, pan long original diff lines without wrapping, +changing, or hiding the original hunk. Press `Enter` to expand or collapse the +full rationale. Outside the focused coach, those keys retain their existing +editor and Git-hunk motions. The older `Space R n` and `Space R p` step bindings +remain compatibility aliases. Use `Space R h` for a hint; it replaces +the rationale in place without moving the change list or the diff. `i`, `a`, +`u`, `m`, `v`, `o`, `f`, `c`, `x`, `X`, `F`, `W`, `r`, `s`, `e`, `d`, `P`, `S`, +`L`, `q`, and `?` act directly on the Replay pane. The `?` key opens an Esc-closeable +shortcut popup and restores focus to the Replay pane on dismissal. The pinned +action bar uses theme-colored, unbracketed keys and keeps source editing, +validation, immediate application, safe undo, change navigation, and help +discoverable without rearranging the review. The changes heading shows the +selected position, while the review metadata reports genuinely completed +changes. A `✓` identifies a manually reconstructed step, `⊕` identifies an +automatic application, and `✎` identifies an actual private note or inline draft. + +Every step always displays its exact, independently parseable unified diff, +including additions and deletions. Challenge mode does not hide the change; it +asks you to reconstruct that visible hunk yourself in the editable scratch +source. Snippet mode keeps the same diff and adds an **ORIGINAL AUTHOR SOURCE** +section containing the resulting original-author text for that hunk. Full +scratch-file images remain editor-owned instead of being copied into every guide +step. Both modes keep the dedicated guide movable and separately focusable from +the real source buffer. + +To apply a step automatically, press `a` while the guide is focused, or use +`Space R a` from either surface. Rust checks the original step, scratch-buffer +revision, authenticated hunk pre-image, and transaction boundary before +immediately applying only that original hunk as one editor transaction. +Unrelated source text is never replaced. Focus stays where the action started; +no confirmation interrupts the reconstruction. + +Press `u` in the focused guide or `Space R u` to undo the latest transaction +only when it belongs to the current Replay session. If a different file is +selected, Replay returns to the exact file and step where that hunk was applied. +If newer manual edits are +present, Replay refuses to skip over them; return to the source and use normal +Vim `u` first. Undoing or subsequently editing a completed current step +automatically removes its completion mark without disturbing earlier +reconstructed steps. Replay explicitly confirms when undo restores the original +scratch source; it reserves the revalidation warning for subsequent manual edits. + +To apply it manually, use `Space R i`, edit the visible Rust buffer to match the +original diff, return to normal mode, and press `Space R v`. A step is marked +complete only when the actual source matches its original post-image. + +For example, on the first exercise focus the source with `i`, jump to the +diagnostic parameter with `:10` and `Enter`, press `o`, type +`visible_start: usize,`, press `Enter`, type `visible_end: usize,`, and press +`Esc`.

An accepted finding can reference an answer, original source, +diagnostic, or trusted build result without changing the original PR. + +## Review draft + +Review drafts remain local until a human confirms publication: + +```text +Inline comment Exact original head, file, GitHub diff side, and line range. +Review summary PR-level feedback with no fabricated inline coordinates. +Suggestion Provider-supported change suggestion on a valid original line. +Code fix note Private author-side intention, never silently published. +``` + +The current `ReplayReviewDraft`, `ReplayReviewAnchor`, `ReplayDraftOrigin`, and +`ReplayDraftState` already enforce exact immutable anchors and local versus +verified-posted state. + +A single finding can produce more than one artifact, but the conversion is +explicit and each artifact records its own provenance. + +## Proposed source patch + +A proposed patch is not an already applied edit: + +```rust +struct ProposedPatch { + id: ProposalId, + snapshot: SnapshotId, + workspace: AuthorizedWorkspaceId, + origin: ProposalOrigin, + files: Vec, + status: ProposalStatus, +} +``` + +Red's existing bounded Codex proposal workspace is authoritative until a person +accepts individual hunks.

Only the editor event loop mutates source buffers or UI. +These ownership boundaries remain unchanged across every milestone. + +## Milestone 0: publish the product specification + +Outcome: + +- A coherent, cross-linked product and engineering specification. +- A shared vocabulary for snapshots, scratch, findings, ordering, Codex, + outcomes, and approval boundaries. +- Clear separation between current behavior and target behavior. + +Acceptance: + +- All documentation links resolve. +- Current operator instructions remain accurate. +- No product document presents a future safety boundary as implemented. + +## Milestone 1: restore stable review surfaces + +User-visible outcome: + +- Replay remains a dedicated, stable original-change pane. +- Source remains a genuine editor window. +- Codex becomes an optional persistent companion instead of replacing the + Replay guide with an answer screen. +- Questions stream into the companion while original source and diff stay + visible. + +Implementation: + +- Reuse existing `PanelManager`, stable text-panel IDs, agent composer, and + streaming primitives. +- Preserve the current guide/source divider, focus, scroll, selections, and + source cursor when the Codex companion opens or closes. +- Add responsive horizontal docking when three columns would be unreadable. +- Retain separate read-only question and explicit draft/fix scopes. + +Acceptance: + +- Wide, standard, and short-terminal captures remain readable. +- `Ctrl-w h/j/k/l`, `Ctrl-w H/J/K/L`, generic resize, and mouse dragging + preserve every pane's state. +- Asking a question never creates a finding, draft, patch, or GitHub review. +- Focus and status indicators identify the active surface correctly. + +## Milestone 2: make findings first-class + +User-visible outcome: + +- Reviewers can record, inspect, investigate, dismiss, and promote findings. +- Existing notes migrate without losing their source anchor or recovery state. +- Codex findings remain provisional until explicitly accepted. + +Implementation: + +- Extend `ReplayNote` or introduce a versioned finding representation linked + to the same original snapshot and hunk identity. +- Record human versus agent origin, evidence, confidence, category, severity, + lifecycle state, and related artifacts. +- Add finding counters to the Replay guide and outbox without displacing the + original diff. + +Acceptance: + +- Existing saved reviews and crash-recovery snapshots continue to load. +- A finding remains private until explicitly converted into another artifact. +- A stale snapshot cannot accept a finding anchored to a different head. +- Codex suggestions cannot silently create durable findings. + +## Milestone 3: unify review outcomes and author fixes + +User-visible outcome: + +- One review session can produce private findings, GitHub feedback, and + separately authorized original-PR patches when permitted. +- The outbox explains available actions without implying unavailable + ownership or provider capabilities. + +Implementation: + +- Project findings, review drafts, verified receipts, and approved proposals + into one coherent outcome view. +- Preserve current exact original diff anchors and verified publication flow. +- Reuse existing original-author worktree verification and Codex proposal + machinery. +- Add independently previewed commit and push flows only after their exact + target branch and remote are modeled safely. + +Acceptance: + +- A reviewer cannot modify someone else's PR branch. +- Original PR owners cannot self-approve or request changes from themselves. +- Unaccepted proposals do not touch buffers or disk. +- Commit and push remain separate explicit decisions. +- Ambiguous provider responses cannot produce duplicate review submissions. + +## Milestone 4: make scratch explicitly on-demand + +User-visible outcome: + +- A reviewer can inspect original PR material before deciding to create a + scratch worktree. +- Manual reconstruction and exact original-hunk application remain prominent, + immediate to discover, and clearly labeled. + +Implementation: + +- Introduce a versioned representation for a review session without an + existing `ReplayWorkspace`. +- Keep exact original source images available for read-only inspection. +- Prompt before materializing the approved durable sibling scratch worktree. +- Upgrade existing recovery and portable-review formats without invalidating + already confirmed scratch sessions. + +Acceptance: + +- Reading the first change does not create a branch or worktree. +- Starting reconstruction previews and confirms the exact scratch identity. +- Existing manual reconstruction, automatic apply, validation, and undo pass + unchanged after scratch exists. +- Denying worktree creation leaves findings and original source available. + +## Milestone 5: decouple hunk identity from presentation order + +User-visible outcome: + +- Existing original order behaves exactly as before. +- Replay can safely represent an alternate order without regenerating hunk + IDs or comment anchors. + +Implementation: + +- Introduce a versioned ordering overlay keyed by exact original hunk IDs. +- Stop assuming presentation index equals raw patch file/hunk traversal index. +- Preserve per-file original hunk order and exact scratch-source images. +- Add an identity-plan migration with no user-visible behavior change. + +Acceptance: + +- Identity-order snapshots match current presentation and existing fixtures. +- Every original hunk appears exactly once. +- Recovered sessions, portable review drafts, comments, and undo attribution + retain stable original identities. +- Completing all hunks yields the exact original author source images. + +## Milestone 6: expose dependency annotations + +User-visible outcome: + +- Original-order steps identify useful prerequisites and dependents. +- Reviewers can understand why another change is relevant without switching + ordering profiles. + +Implementation: + +- Extract deterministic structural edges from patch paths, file creation, and + existing same-file order. +- Add conservative Rust/TOML heuristics for modules, manifests, definitions, + and references. +- Track confidence and ignore ambiguous symbol matches. + +Acceptance: + +- Wrong or ambiguous analysis cannot block a normal review. +- Parse failures fall back to raw behavior without losing original hunks. +- Dependency direction is always prerequisite to dependent. +- Module creation is shown before its registration. + +## Milestone 7: add foundations-first reconstruction + +User-visible outcome: + +- Reviewers can switch between original and foundations-first profiles. +- Reconstruction can present definitions and new modules before their users. + +Implementation: + +- Condense required semantic dependency cycles into explicit logical groups. +- Topologically order groups with original ordinal as the stable tie-break. +- Display original hunk membership, group rationale, and cross-file source. +- Apply grouped hunks through safe composite editor transactions. + +Acceptance: + +- Same-file relative hunk order never changes. +- Applying every group reproduces the exact pinned original head. +- An incompatible plan falls back to original order and explains why. +- Atomic group undo refuses to discard newer unrelated manual edits. + +## Milestone 8: offer trusted compile checkpoints + +User-visible outcome: + +- A reviewer can explicitly authorize checking meaningful completed groups. +- Checkpoints show honest pending, running, passed, failed, unavailable, or + not-authorized states. + +Implementation: + +- Preview the exact untrusted-code execution risk, source identity, workspace, + package selection, and command. +- Materialize only approved scratch images in an isolated review location. +- Prefer bounded, package-scoped, lockfile-preserving, offline checks. +- Collect bounded diagnostics and invalidate grants when the PR head changes. + +Acceptance: + +- A PR-controlled build script, macro, wrapper, or test never executes before + explicit approval. +- Checks remain cancelable and do not block editor input. +- A failed base or original PR head is reported rather than hidden. +- No automatic checkpoint creates a commit, pushes a branch, saves unrelated + source, or downloads dependencies. + +## Validation strategy + +Every milestone requires: + +- Focused unit coverage for the new state transition or data invariant. +- Integration coverage through real `PluginRequest` and editor-event + boundaries. +- Regression coverage for source editing, exact hunk application, validation, + replay undo, session recovery, and portable review bundles. +- UI rendering and keyboard coverage at large and constrained terminal sizes. +- Real-PR dogfooding for multi-file and agent-generated review flows. +- Full workspace tests and the repository-required strict Clippy command when + Rust changes are involved. +- The repository's Markdown link checker when documentation changes. + +Suggested ordering-specific golden cases: + +```text +Manifest dependency before its first import. +New module file before mod registration. +New definition before independent cross-file users. +Changed trait signature and implementation updates in one atomic group. +Removal after every changed caller no longer references the symbol. +Ambiguous duplicate symbol names with deterministic fallback. +Rename followed by edits under the new path. +Existing same-file hunks whose context shifts after earlier changes. +Untrusted build refusal, explicit approval, cancellation, and stale snapshots. +``` + +## Settled product decisions + +- There is one review session with capability-driven outcomes. +- Hands-on scratch reconstruction remains a core feature. +- Scratch may be initialized on demand. +- The original PR snapshot and original hunk anchors remain immutable. +- Answers, findings, comments, and source patches are separate concepts. +- A finding can become private feedback, an original-source review comment, + or an explicitly authorized source proposal. +- Reviewer-source and original-author-source worktrees remain separate. +- Original order and foundations-first reconstruction can coexist. +- Compilation is best-effort, opt-in, and treated as untrusted code execution. +- Commit, push, publication, and source proposal approval are separate gates. + +## Open decisions + +- Exact final shortcuts for the Codex companion, findings, and ordering switch. +- Which responsive layout thresholds choose a right-side panel versus a bottom + drawer. +- Whether foundations-first becomes the default only after scratch begins or + is always an explicit selection. +- Whether finding creation from a human-authored question needs a one-step + shortcut or an explicit editor. +- How provider-compatible GitHub suggestion blocks are represented in the + local outbox. +- Whether trusted compile grants are per snapshot, per repository, or per + exact command. +- Whether package-scoped checks should include workspace feature profiles. +- How logical group undo should compose existing per-buffer editor undo trees. + +## Explicitly deferred + +- rust-analyzer-grade global name resolution. +- AI-authored ordering as an authoritative planner. +- Guaranteed compilation after every raw original hunk. +- Multi-language dependency extraction before Rust ordering is reliable. +- Arbitrary user drag-reordering of individual prerequisite-bearing hunks. +- Automatic network dependency downloads. +- Silent remote review retries, automatic commits, or automatic pushes. + +See [the product

The +current overlay groups changes but does not reorder them; changing the visible +list order independently would still violate same-file prerequisites and +source-image assumptions. + +## Separate original identity from presentation order + +Original hunk identity belongs to the pinned snapshot: + +```text +Original Hunk A src/lib.rs original ordinal 01 +Original Hunk B src/pagination.rs original ordinal 02 +``` + +A reconstruction profile is an overlay: + +```text +Original order: A → B +Foundations-first order: B → A +``` + +Both profiles reference exactly the same hunk IDs, source digests, original +paths, changed lines, before/after text, and GitHub anchors. + +The presentation position of a hunk must not become its immutable identity. +Recovery, notes, findings, comments, and Codex context remain anchored to the +original hunk ID rather than an order-dependent row number. + +## Ordering profiles + +### Original order + +Preserve the current Git-emitted file and hunk order. This profile remains +stable, matches familiar provider diff presentation, and is useful when a +reviewer wants to begin from an entry point or high-level behavior. + +The dependency graph can still annotate the original order: + +```text +01 Update app.rs + Requires PaginationState, introduced in change 07. + +07 Add PaginationState + Used by changes 01, 03, and 11. +``` + +### Foundations-first order + +Order prerequisites before dependents where a safe relationship can be +established. The same example becomes: + +```text +01 Create src/pagination.rs. +02 Add PaginationState. +03 Register mod pagination;. +04 Update app.rs to use PaginationState. +05 Add regression coverage. +``` + +Foundations-first is especially appropriate when the reviewer enters scratch +reconstruction. The product can offer or select it at that point without +forcing it on someone who only wants to read the PR. + +### Future narrative profiles + +Author-commit order, intent-first order, and test-first order are possible +future projections. Commit chronology is useful only when the author commits +are independently meaningful; a squashed PR cannot supply a narrative it does +not contain. + +These profiles are not required for the first dependency-aware milestone. + +## Dependency graph + +Dependency edges are directed from prerequisite to dependent: + +```text +Create module file → Register module declaration +Add Cargo dependency → Import the new dependency +Define a type → Use the type in another file +Define a trait → Add its implementation +Earlier same-file hunk → Later same-file hunk +Update a caller → Remove the old called function +``` + +The direction must always be explicit. In particular, a Rust module file must +exist before the `mod name;` declaration that causes the compiler to load it. + +### Hard structural dependencies + +Hard edges preserve patch applicability and source identity: + +- An earlier hunk in the same file precedes a later hunk in that file. +- Creating a file precedes later edits to that newly created file. +- A verified rename or move is grouped with edits that require its new path. +- A file cannot be removed before hunks that still require its original image. + +Every valid profile preserves the raw relative order of hunks within each file. +Therefore the reconstructed state of any individual file is always a contiguous +prefix of its original hunk sequence. + +This prefix invariant lets existing scratch images, hunk context, line-delta +calculation, revision checks, and unique pre-image validation remain valid +while independent files interleave differently. + +### Semantic dependencies + +Semantic edges describe likely definition-before-use relationships: + +- New module file before its registration. +- Manifest dependency before imports from the new crate. +- Struct, enum, trait, function, constant, macro, or re-export before another + changed file references it. +- Trait definition before an added implementation. +- A changed API and its verified call-site updates. +- Relevant implementation changes before related tests. +- Removal of callers before removing a provider they still reference. + +Use confidence levels. A relationship established from exact path, module, and +symbol evidence can influence reconstruction. Ambiguous same-name symbols, +macros, conditional compilation, generated code, and external crates must not +be treated as facts merely because identifiers match. + +Uncertain relationships should be shown as suggestions or dropped; they must +not invalidate an otherwise safe review. + +## Extracting dependencies + +Start with existing patch metadata and cheap deterministic file classification: + +```text +Cargo.toml / Cargo.lock +New modules and new source files +Changed definitions and exports +Call sites and configuration wiring +Tests +Documentation and generated artifacts +Safe removals after their consumers +``` + +For Rust, Red already includes Tree-sitter Rust and TOML grammars. Parse the +original base and original head images and inspect changed regions for: + +- `mod`, `use`, `pub use`, and qualified paths. +- Function, type, trait, implementation, macro, and constant definitions. +- Added function calls and changed type references. +- `[dependencies]`, workspace dependencies, and feature changes. +- `#[cfg(test)]`, integration-test paths, and test attributes. + +Prefer same-module and same-crate evidence. If several possible definitions +remain, do not guess. A parse failure degrades only the affected file to raw +structural ordering. + +Do not initially depend on a running language server, rust-analyzer name +resolution, a Codex model call, or an unapproved repository build to produce a +usable ordering plan. + +## Atomic multi-file groups + +Some final states cannot be reached through individually compiling hunks. + +For example: + +```text +src/retry.rs Change RetryPolicy::next_delay signature. +src/client.rs Update the first implementation. +src/worker.rs Update the second implementation. +tests/retry.rs Update the associated call. +``` + +No single hunk can guarantee a compiling intermediate repository. These hunks +can become one logical replay group: + +```text +Group 08 · Update the retry interface · 4 original hunks +``` + +Group behavior: + +- Preserve every exact original hunk and its GitHub anchor. +- Show all affected files before application. +- Allow manual inspection or reconstruction of each member. +- Treat automatic group application as an explicit composite operation. +- Validate completion only after all required members are present. +- Run optional compilation only after the group is complete. +- Undo a composite application safely without skipping newer manual edits. + +Use strongly connected components only for required or high-confidence +semantic cycles. Low-confidence soft cycles should be discarded or weakened; +they must not collapse half a PR into one opaque group. + +A structural hard-edge cycle is invalid. Fall back to original order rather +than manufacturing a false dependency resolution. + +## Stable topological ordering + +After grouping necessary cycles, topologically order the resulting group graph. +If several groups are ready, prefer the one containing the lowest original +hunk ordinal. This stable tie-break preserves the existing narrative wherever +dependency analysis does not justify a change. + +Planner failure conditions include: + +- Original-hunk coverage differs from the pinned snapshot. +- A hunk appears in multiple groups or no group. +- A same-file relative ordering changes. +- A required edge points backward in the final result. +- Parsing exceeds its bounded time or memory budget. +- The original snapshot moves or cannot be verified. + +Failure falls back to original order and explains why. It never rewrites the +original review or destroys reconstruction progress. + +## Scratch lifecycle + +The target session can show original source before creating a worktree. Scratch +materializes only when the person explicitly chooses a filesystem-backed +action, such as: + +- Reconstruct this change manually. +- Apply the original hunk or group. +- Run an approved build or test. +- Experiment with an alternative implementation. + +Creation previews the exact durable sibling worktree, scratch branch, original +repository, and merge base. The original checkout and PR branch remain +unchanged. + +Automatic hunk application changes editor-owned scratch buffers. It does not +silently save them. A trusted build that requires real files must explicitly +materialize the exact approved scratch images in an isolated review workspace; +it must never save unrelated original-PR buffers as a side effect. + +Scratch remains reconstructable from its pinned base and approved replay +history. Temporary compile checkpoints do not create throwaway Git commits, +rewrite the reviewer branch, or publish anything. + +## Compilation checkpoints + +The achievable promise is: + +> Keep scratch code compilable at meaningful replay-group boundaries when the +> original repository and environment allow it. + +Never claim that every raw hunk compiles. An unchanged base may already fail, +the original PR head may fail, features may differ, generated sources may be +missing, or a change may require an indivisible cross-file group. + +A checkpoint records: + +```text +Snapshot and scratch identity. +Completed original hunk IDs. +Exact command and feature configuration. +Packages examined. +Permission and isolation policy. +Result, bounded diagnostics, duration, and cancellation state. +``` + +Suggested states: + +```text +NOT RUN The reviewer did not request compilation. +NOT AUTHORIZED Untrusted code execution was not approved. +RUNNING An approved, bounded background build is active. +PASSED The recorded approved command succeeded. +FAILED The recorded command failed; diagnostics are inspectable. +UNAVAILABLE No safe command or reproducible build configuration exists. +``` + +Package-scoped `cargo check -p ` can reduce cost when changed paths map +unambiguously to workspace members.
