Preserves complete review discussion when it fits the existing 24,000-character section budget. A 4,000-character fragment boundary no longer clips a longer human comment or a User-account report and falsely makes the review partial.

The pure packing policy normalizes and sanitizes before splitting, preserves surrogate pairs and non-colliding untrusted framing, counts logical sources rather than fragments, and includes metadata, separators and omission notices in the final budget. Native automated-author filtering remains unchanged. Actual omissions, oversized sources, malformed Unicode and incomplete diff evidence cannot be presented as complete; approval rules remain in force.

Validation:

• Full coverage run: 717 Jest suites / 12,143 passing tests, plus 56 extension tests. All existing coverage budgets pass. The new policy and existing context builder have 100% statements, branches, functions and lines covered. The final mandatory commit checks also pass: 717 suites / 12,144 tests, including the additional presentation regression.
• The 13 required SDD case IDs cover reconstruction, Unicode, framing, exact budgets, native provider metadata, the real loader, independent partial sources and guarded approval. Architecture checks keep the policy free of infrastructure dependencies.
• Real-source replay reconstructs both the 5,959-character Codecov report and the human issue comment identified as truncated by PR feat: Browser extension H2 browser runtime lifecycle protected sessions and actual browser harnesses (#703) #719. Existing partial-state UI was inspected at 390 × 844 pixels: completed diff, incomplete conversation, source identity, next action and navigation links remain readable without color.
• Build, types, lint, specification/catalog and documentation validation pass. Tracked Action, CLI and API bundles are rebuilt. The owning SDD, companion, catalog and Bugbot documentation describe the same contract.

Remote verification at 50d084cdac077fa1a694a361d4527f1406003214: CI Check, Branch Sync, Commit, Pull Request and all hosted Linux/macOS/Windows platform jobs pass. Bugbot completes both diff partitions with complete input coverage and zero findings. Codecov reports 100.00% patch coverage and zero missed lines in both changed source files. The guarded Approval check is neutral by design (protected-path); it recommends a human decision and has not issued an automatic approval. Merged into develop as 70ce428342202b0eb320868134dc453f20ee575a after the maintainer explicitly confirmed this PR and its neutral protected-path recommendation. No administrative check bypass was used. Local replay is not a claim that PR #719 has already rerun successfully. This implements the published companion's generic lossless design; it does not add trusted-producer classification or public configuration.

Closes #724
