Two issues here:
- Typo:

Result<_, _>rather than panicking. This arm can be triggered at runtime if a deltaObjectTypevariant is passed toto_bytes().

Pull request overview
This PR expands the AI object model in git-internal by adding a new Intent and ContextPipeline object, heavily documenting AI object lifecycles/relationships, and tightening boundaries so AI extension objects cannot flow through standard Git pack encode/decode paths.
Changes:
- Add new AI object types (
Intent,ContextPipeline) and evolve shared AI header/type utilities. - Enforce “no AI objects in packfiles” at pack encode/decode boundaries.
- Add extensive module/file documentation and update repository docs/metadata accordingly.

PlanStep::status() panics on malformed / externally-provided data (statuses.last().expect(...)). Since PlanStep is deserialized from JSON, a missing or empty statuses array would crash consumers. Prefer returning Option<&StepStatus>, or enforce/repair the invariant during deserialization (e.g., #[serde(default)] + custom deserialize that injects an initial Pending entry when empty).

Intent::status() panics if statuses is empty (.expect("statuses is never empty")). Because this type is deserialized from JSON, invalid or legacy data could cause a hard crash. Prefer returning an Option<&IntentStatus> (and letting callers handle it) or enforcing the invariant during deserialization by defaulting/patching an initial Draft entry when statuses is missing/empty.

PR description mentions adding an UnsupportedAiObjectType error variant, but the enum currently only adds InvalidIntentObject / InvalidContextPipelineObject. If pack-boundary rejection is meant to use a dedicated error, add it here (and update pack encode/decode to use it), or update the PR description to match the actual change.

push_frame + evict_if_needed physically removes elements from frames, which shifts all subsequent indices. Since PlanStep.iframes/oframes store frame indices, eviction will silently corrupt those references (steps will point to the wrong frames after an eviction). Consider using stable frame IDs (monotonic frame_id stored in ContextFrame), or keep a base_index/tombstone strategy (e.g., Vec<Option<ContextFrame>>), so references remain valid across eviction.

Doc comment says eviction removes the "oldest non-Checkpoint" frame, but the implementation also protects IntentAnalysis frames from eviction. Update the comment to match the actual eviction rule (oldest non-protected frame).
- PlanStep.statuses: add #[serde(default)] with a Pending-entry default so legacy plans with the old single `status` field can still deserialize. - Header.updated_at: replace Utc::now() default with a custom Deserialize impl that falls back to created_at, avoiding nondeterministic metadata when loading legacy objects.

There was a problem hiding this comment.
In the Intent module, the field is renamed from content (which was a required String) to separate prompt (required) and content (optional). However, there's a naming inconsistency:
- Line 208: The field is named
prompt - Line 290: The getter is
prompt() - Line 295: There's also a getter
content()that returnsOption<&str>
But in the old version shown in the PR description, content was the field that held the user input. Now prompt holds the raw user input and content holds the AI's interpretation. This is a good semantic split, but the field previously named content has been renamed to prompt, and a new optional content field has been added.
This is a breaking change that affects serialization compatibility. Existing serialized Intent objects will have content as a required string, but the new schema expects prompt as required and content as optional. There's no #[serde(alias = "content")] on the prompt field to handle backward compatibility.
Consider adding:
#[serde(alias = "content")]
prompt: String,This would allow old serialized data with content to be deserialized into the new prompt field.

The PlanStep.status field has been removed and replaced with PlanStep.statuses (a Vec<StepStatusEntry>). However, there's no backward compatibility handling for deserialization.
Old serialized data will have:
{"intent": "...", "status": "pending"}New schema expects:
{"description": "...", "statuses": [{"status": "pending", ...}]}The #[serde(alias = "intent")] on line 251 handles the intent → description rename, but there's no migration logic for status → statuses. When deserializing old data, statuses will default to [Pending] via default_step_statuses(), but the original status value will be ignored.
This could silently lose status information. Consider a custom deserializer or add a test verifying old format handling.

The PatchSet.generation field has been removed without backward compatibility. Old serialized PatchSets will have a generation field that will be silently ignored during deserialization.
Additionally:
supersedes_patchset_idsfield removed (line 293 in old code) — no longer trackedvalidate_supersedes()method removed (lines 313-330 in old code)
Ordering is now determined by position in Run.patchsets, which is fine, but deserializing old PatchSets will lose the generation number. If the generation number is important for migration or historical analysis, consider preserving it during a transition period with #[serde(default, skip_serializing)].

The expect() call here provides a generic error message that doesn't identify which object type caused the problem. Since to_bytes() now returns None for delta types (OffsetDelta, HashDelta, OffsetZstdelta), the panic message should be more specific.
Consider using:
.unwrap_or_else(|| panic!("ReadBoxed::new called with delta type {:?} that has no loose-object header", obj_type))This provides better diagnostics when debugging issues with delta types being incorrectly passed to this function.

The expect() message is accurate and helpful — it correctly identifies the issue if calculate_object_hash is called with a delta type. The error context is clear from the function name in the message.
However, for consistency with the pack encode path (where to_pack_type_u8() returns a proper GitError::PackEncodeError), consider whether this should return a Result instead of panicking. Delta types reaching here would indicate a logic error in the pack handling code, but a typed error would be more idiomatic Rust.

The removal of the repo_id parameter from Header::new() is a breaking API change. While the PR description mentions "breaking API changes in patch releases" are allowed for 0.5.x, this is now version 0.6.0.
All existing code creating AI objects will need to be updated to remove the repo_id argument. The change makes sense conceptually (UUID v7 already provides global uniqueness), but ensure that:
- All downstream consumers are notified of this breaking change
- Migration notes explain why
repo_idwas removed - The CHANGELOG documents this as a breaking change
The tests have been updated correctly to use the new signature.

The is_base() implementation has been changed to only return true for the four standard Git object types (Commit, Tree, Blob, Tag), excluding AI object types. The documentation correctly states: "AI object types return false because they cannot be encoded in pack files and should never participate in delta window selection."
This is consistent with the pack boundary enforcement added elsewhere in the PR. However, verify that all call sites of is_base() handle the new behavior correctly. AI objects were previously considered "base" objects, so this is a semantic change that could affect delta compression logic.
