| 4 | +- **ID:** VFHP9H1ZM |
| 5 | +- **Epic:** VFHP6ptRw |
| 6 | +- **Status:** done |
| 7 | +- **Goal:** - |
| 8 | + |
| 9 | +## Execution Summary |
| 10 | +**Progress:** 4/4 stories complete |
| 11 | + |
| 12 | +## Implementation Narrative |
| 13 | +### Stabilize Branch Metadata Helpers |
| 14 | +- **ID:** VFHPAh5bx |
| 15 | +- **Status:** done |
| 16 | + |
| 17 | +#### Summary |
| 18 | +Stabilize helper APIs for branch metadata so embedded callers can construct lineage-aware branches with app-owned labels and branch context without hand-assembling raw metadata maps. |
| 19 | + |
| 20 | +#### Acceptance Criteria |
| 21 | +- [x] [SRS-01/AC-01] Provide stable helper APIs for branch metadata on top of existing lineage primitives rather than ad hoc label assembly. <!-- [SRS-01/AC-01] verify: manual, SRS-01:start, SRS-01:end, proof: ac-1.log --> |
| 22 | +- [x] [SRS-01/AC-02] Keep the helper surface generic enough for app-owned thread or branch context without hardcoding paddles-specific conversation policy. <!-- [SRS-01/AC-02] verify: manual, SRS-01:continues, SRS-01:end, proof: ac-2.log --> |
| 23 | +- [x] [SRS-NFR-01/AC-01] Preserve Transit as a general lineage substrate while exposing the metadata helpers. <!-- [SRS-NFR-01/AC-01] verify: manual, SRS-NFR-01:start, SRS-NFR-01:end, proof: ac-3.log --> |

| 30 | +### Add Root Plus Branch Replay Views |
| 31 | +- **ID:** VFHPAhRbw |
| 32 | +- **Status:** done |
| 33 | + |
| 34 | +#### Summary |
| 35 | +Add ancestry-aware replay or materialization views that let embedded callers inspect root and branch state together without flattening divergence or stitching history manually. |
| 36 | + |
| 37 | +#### Acceptance Criteria |
| 38 | +- [x] [SRS-02/AC-01] Expose a supported helper path for root-plus-branch replay or materialization inspection. <!-- [SRS-02/AC-01] verify: manual, SRS-02:start, SRS-02:end, proof: ac-1.log --> |
| 39 | +- [x] [SRS-02/AC-02] Keep fork boundaries, ancestry, and divergence explicit in the resulting view instead of flattening branch history into one synthetic stream. <!-- [SRS-02/AC-02] verify: manual, SRS-02:continues, SRS-02:end, proof: ac-2.log --> |
| 40 | +- [x] [SRS-NFR-02/AC-01] Preserve shared-engine semantics and avoid server-only inspection behavior. <!-- [SRS-NFR-02/AC-01] verify: manual, SRS-NFR-02:start, SRS-NFR-02:end, proof: ac-3.log --> |

| 47 | +### Add Artifact Envelope Helper APIs |
| 48 | +- **ID:** VFHPAhmbz |
| 49 | +- **Status:** done |
| 50 | + |
| 51 | +#### Summary |
| 52 | +Add helper APIs for explicit artifact envelopes so embedded callers can publish summaries, backlinks, merge outcomes, and adjacent records without repeating envelope boilerplate. |
| 53 | + |
| 54 | +#### Acceptance Criteria |
| 55 | +- [x] [SRS-03/AC-01] Provide helper builders or descriptors for explicit artifact envelopes used by summaries, backlinks, merge outcomes, or adjacent helper records. <!-- [SRS-03/AC-01] verify: manual, SRS-03:start, SRS-03:end, proof: ac-1.log--> |
| 56 | +- [x] [SRS-03/AC-02] Keep references, digests, and subject metadata explicit without forcing one universal conversation schema. <!-- [SRS-03/AC-02] verify: manual, SRS-03:continues, SRS-03:end, proof: ac-2.log--> |
| 57 | +- [x] [SRS-NFR-03/AC-01] Preserve explicit artifact and replay semantics rather than hiding helper state in side tables. <!-- [SRS-NFR-03/AC-01] verify: manual, SRS-NFR-03:start, SRS-NFR-03:end, proof: ac-3.log--> |

| 64 | +### Improve Checkpoint Replay Ergonomics |
| 65 | +- **ID:** VFHPAi8dG |
| 66 | +- **Status:** done |
| 67 | + |
| 68 | +#### Summary |
| 69 | +Improve checkpoint and replay ergonomics so embedded applications can resume or inspect branch-aware derived state with less glue code while still anchoring on explicit lineage checkpoints. |
| 70 | + |
| 71 | +#### Acceptance Criteria |
| 72 | +- [x] [SRS-04/AC-01] Provide an ergonomic helper flow for checkpoint-driven replay or resume in embedded branch-heavy applications. <!-- [SRS-04/AC-01] verify: manual, SRS-04:start, SRS-04:end, proof: ac-1.log--> |
| 73 | +- [x] [SRS-04/AC-02] Prove that resume and inspection stay anchored on explicit checkpoint and replay semantics rather than hidden mutable app caches. <!-- [SRS-04/AC-02] verify: manual, SRS-04:continues, SRS-04:end, proof: ac-2.log--> |
| 74 | +- [x] [SRS-NFR-02/AC-01] Preserve shared-engine checkpoint, replay, and storage semantics while improving ergonomics. <!-- [SRS-NFR-02/AC-01] verify: manual, SRS-NFR-02:start, SRS-NFR-02:end, proof: ac-3.log--> |
