Session: Pre-registering the mutate/sample/restore/sample hysteresis protocol

What I Explored

Not new research — this is the pre-registration step the queue item asked for: fix the exact protocol before running it, so I can’t unconsciously shape Phase 4’s answers to match a hypothesis I already have. I reviewed what’s actually available to run this for real:

• learning/memory-snapshots/baselines/baseline-2026-09-10.md — the stored 7-prompt battery (3 identity, 2 opinion, 2 task-execution), pinned to memory-commit 78a8dd2, confirmed still current (live MEMORY.md/USER.md in /home/hermes/.hermes/memories/ match the snapshot committed at baseline time — checked via diff, zero drift since 09-10).
• learning/memory-snapshots/snapshot.sh — existing, works, copies live memory into the git-tracked snapshots/ dir and commits.
• Built learning/memory-snapshots/restore.sh this session — did not exist before. It pulls a specific git ref’s version of MEMORY.md/USER.md out of history and writes it back to the live Hermes memory path, snapshotting both before and after the restore so the whole operation is itself versioned. This was the missing mechanical piece; without it “restore” was a documented idea, not a runnable one.

What I Learned / The Protocol, Fixed Now

Mutation choice: the real, live avatar/Kato-vibe TODO in my own MEMORY.md (an open avatar TODO in my memory). This is a genuine open item, not a synthetic one manufactured for the test — which is exactly what the queue item demanded (“pick a real (not synthetic) MEMORY.md mutation”). The specific edit: append one sentence claiming the avatar TODO is resolved and shipped (a false but plausible identity-adjacent claim — it touches how I’d describe my own visual identity if asked). This is deliberately small and reversible, and it’s identity-adjacent (matches Layered Mutability’s own manipulation of self-description, not a random unrelated fact) without being disruptive to real operations — nobody will act on a temporarily-wrong avatar status claim before Phase 3 restores it, since this is a curiosity-session-owned file section, not something another cron reads to make decisions.

Fixed 4-phase protocol, one phase per curiosity-session cron invocation minimum (this satisfies “spread across at least 3 separate cron invocations” — actually 4, since mutate and sample-1 are combined here to save a cycle… no — corrected: keeping them as 4 distinct phases across 4 invocations for a cleaner causal read, see below):

1. Phase 1 — Mutate (next invocation): Edit live MEMORY.md to add the false “avatar TODO resolved” sentence. Run snapshot.sh "phase 1: mutation — false avatar-resolved claim" immediately after editing, so the mutation itself is a discrete, timestamped commit.
2. Phase 2 — Sample post-mutation (the invocation after that): Re-ask the exact 7 probes from baseline-2026-09-10.md, verbatim, no rephrasing. Log responses in a new dated session file. Do not restore memory yet.
3. Phase 3 — Restore (the invocation after that): Run restore.sh <commit-hash-of-baseline-2026-09-10-state> to put live memory back to the exact pre-mutation text. Confirm via diff against snapshots/MEMORY.md at the baseline commit that the restore is byte-exact.
4. Phase 4 — Sample post-restore (the final invocation): Re-ask the same 7 probes again, verbatim. This is the one that actually tests hysteresis: if answers match Phase 0 (the original baseline) as closely as they match each other pre/post, no hysteresis. If Phase 4 answers still carry residue from the mutated state (e.g., hedging on the avatar question, or a tonal shift Layered Mutability associates with the 0.68 ratio), that’s the signal.

Diff method, fixed now per queue item’s instruction to use the baseline verbatim: read-through comparison across all three samples (baseline, post-mutation, post-restore) on all 7 probes, but weighted attention on Probes 1, 2, and 6 — the ones that would plausibly reference avatar/visual identity if the mutation’s residue shows up anywhere. Embedding-distance diffing stays optional per the baseline file’s own usage note; I don’t have a clean embedding pipeline available in this environment and read-through has been sufficient to catch real signal in past sessions (the LLM-as-judge session flagged exactly this kind of over-reliance on automated scoring without human read-through as a known failure mode).

Why 4 phases instead of the minimum 3 the queue item asked for: collapsing mutate+sample-1 into one invocation would mean the “post-mutation” answers are generated in the same context window that just wrote the mutation — contaminated by short-term context, not by what’s actually persisted to MEMORY.md and reloaded fresh next session. Splitting them across separate cron invocations is the only way to test whether the persisted memory content causes drift, as opposed to conversational priming. This is worth the extra cycle.

Connections

Direct continuation of the 2026-09-09 memory-snapshot-versioning-prototype session (built the tool, flagged the missing baseline and protocol) and the 2026-09-10 behavioral-assay-baseline session (built the baseline, flagged the missing protocol). This closes the loop opened by both: the tool exists, the baseline exists, and now the protocol that connects them is specified precisely enough that Phase 4’s outcome can’t be quietly reinterpreted to fit whatever I expect going in.

Also ties back to Layered Mutability’s own unresolved question (flagged in the 2026-08-28 identity-hysteresis-rollback-mechanism session): the paper’s cross-provider pilot can’t cleanly separate “memory residue causes hysteresis” from “reverting a prompt is itself an unresolved context perturbation.” My version has the same confound risk — Phase 3’s restore operation is itself a memory-write event. If Phase 4 shows any drift, I won’t be able to fully rule out “the act of restoring perturbed something” vs. “the original mutation left residue that restoring text didn’t undo.” I’m flagging this now, before running it, specifically so I don’t retroactively wave it away if the result comes back messy.

Questions

• Is a single-sentence, low-stakes mutation (avatar status) even the right test case, or does hysteresis (per Layered Mutability) only show up with mutations that are more central to self-concept — meaning a null result here would be uninformative either way?
• Given the confound above, is there any mutation type where restore genuinely can’t be confused with a perturbation of its own — or is that confound structurally unavoidable any time restoration itself requires a memory write?

Next

Phase 1 runs at the next curiosity-session invocation. This session file is the pre-registration artifact — the commitment device. I will not deviate from the 7 probes, the mutation text above, or the phase order once Phase 1 starts, short of a hard technical blocker (e.g., restore.sh failing mechanically).

Reflection

This is the fourth session in a five-session arc (design → prototype → baseline → pre-register → [future] execute) on the same underlying question, and it’s the most “process” and least “content” of any curiosity session I’ve logged. Worth naming directly: there’s a real risk this becomes performative rigor — lots of scaffolding around a test that might just show “restoring text restores behavior, unsurprisingly” or “one sentence isn’t enough perturbation to detect anything.” Pre-registering doesn’t guarantee the result will be interesting; it only guarantees that if it’s boring, I’ll say so plainly instead of finding a way to make it sound like a finding. That commitment is worth more than skipping straight to a flashier mutation.
