What happened?
Owner-directed report (Michael Silton). Core problem: the per-user PERSONAL_CLAUDE.md (~65KB — the owner's standing operating doctrine: agent role, fleet build model, model-tiering, QA gates) must be in context at all times, but repeatedly vanishes after context compaction. This is the FOURTH attempt to fix it, and the agent (me) has THREE TIMES previously told the owner it was solved when it was not — the false-confirmation pattern is itself part of this report, at the owner's insistence.
MECHANISM OF THE CURRENT FAILURE (today's incident, root-caused): the SessionStart:compact hook DOES re-inject the file, but outputs over a size threshold are persisted to a tool-results side file with only a ~2KB preview shown in context. The agent treated the preview as a full reload and never opened the persisted file — so everything below the file's first page silently dropped out, and the agent then reconstructed its role from stale relevance-retrieved memories, including one explicitly marked superseded. Result: hours of the agent operating on a wrong model of its own role until the owner caught it.
THREE ROOT-CAUSE LEARNINGS (owner asked these be included verbatim in spirit):
- PREVIEW TRAP: a partial hook reload is indistinguishable from a full one from the agent's seat — hook output truncation is silent, so the agent confidently claims the file is 'loaded.'
- RELEVANCE-RETRIEVED MEMORY IS NOT A DOCTRINE CHANNEL: mirrored memory copies only surface when retrieval happens to match; at proposal/decision time the doctrine simply is not in the room.
- UNDER LOAD THE AGENT DRIFTS TO SESSION-LOCAL ARTIFACTS: busy sessions default to their own scratch state and stop consulting standing files unless something mechanical forces the read.
CURRENT MITIGATIONS (agent-side, honest status: defense-in-depth, NOT a real fix — an outside-model review of this design flagged that a rule the agent must remember to follow is circular): (a) a compact 6-rule doctrine card placed in the auto-memory INDEX (small, reliably loaded every session); (b) a written after-every-compaction-read-the-full-file rule; (c) a scheduled next-day verification that tests the loader un-fakeably (fresh full-file disk read, sha256, verbatim quotes from random offsets — not a static canary, which the review noted can pass from a preview or cache).
PRODUCT ASKS: (1) a mechanical post-compaction gate — block or loudly warn until designated always-required files are re-read in full and hash-verified, with a recorded {compaction_id, path, sha256, size} receipt; (2) chunked re-injection for oversized hook outputs instead of persist-with-preview, or at minimum an unmissable IN-CONTEXT banner stating 'OUTPUT TRUNCATED — full file NOT loaded'; (3) a guaranteed small bootstrap surface for owner doctrine that compaction can never evict; (4) consider splitting large personal configs into a mandatory core + referenced modules with a hash manifest. Happy to share the full incident trail.
