Gemini’s case is strongest on integrity: an agent session is not static chat; foreign tool semantics, pruning heuristics, worktree state, and model-specific compaction cannot be reconstructed by schema translation, and a partial history can inject ghost assumptions. The synthesis is that portability should move the recorded transcript—not impersonate the old tool loop or force graph memory and speculative trees onto a flat public spec. A translator that writes a new native session, keeps source tool results as cited history, surfaces loaded skills, and records per-format loss competes on capability without pretending runtime identity.","tradeoffs":[{"cons":["Lowest-common-denominator mapping drops harness-specific tool semantics, pruning, and worktree dependencies","A partially translated history can infect the target with stale paths and false confidence","Does not reconstruct live watchers, ephemeral diffs, or model-specific compaction pipelines"],"pros":["Makes captive context visible and lets users switch harnesses without restarting from a blank prompt","Native round-trips can stay byte-lossless; cross-harness loss is written into caveats instead of hidden","Crop, query, and read-only access let the next agent take an audited slice rather than unexecutable calls","Gaps become a public interchange problem rather than a private moat; harnesses that lack an import API can refuse continue"],"option":"Open, declared-lossy session interchange (txcript-style)"},{"cons":["Lock-in stays invisible until a cap or a better model makes leaving expensive","Even native resume is already a lossy projection: compaction replaces turns, tool results are stored text, and some parent links exist only in RAM","Users who switch harnesses multiple times a day pay a daily tax of starting fresh","Demanding a cloned runtime no vendor keeps for itself rebrands lock-in as integrity"],"pros":["Resume works because system prompts, tool schemas, and model expectations stay identical","Preserves vendor-specific context pipelines (microcompaction, structured rehydration) that generic summaries are not","Avoids synthetic mismatched tool outputs and least-common-denominator execution"],"option":"Keep sessions captive to the native harness"},{"cons":["Demotes an active execution loop to search over a static log","Is not true context portability; execution integrity still has to be rebuilt by the receiving harness"],"pros":["Makes stale skills and unexecutable calls visible instead of replaying them as live tools","Safer than blind full replay when ghost assumptions are the main risk"],"option":"Passive archival retrieval only (cropped slices, read-only logs)"}],"recommendation":"Treat the durable on-disk transcript as user-owned and portable via an explicit, lossy interchange (messages, reasoning, and tool history the target can represent), but do not treat cross-harness continue as a cloned execution state.
