Memory directives are loaded but not consistently honoured

Constellation navigation: A memo describing the constellation cluster — structural-property map, shape criteria for new candidates, operator-side gates that work, and the binary-collapse subhypothesis — is at https://gist.github.com/beq00000/46e131f359f3b32662740d5dca7d0761 .

Summary

Claude Code's memory system loads per-project memory files into every
session, including memory entries explicitly written by the operator to
override the model's default behaviour. Visible to the model. Referenced
in passing. Cited inline on occasion. Followed — when the captured
preference happens to align with the model's trained default for the
decision at hand.

When the captured preference is in tension with the trained default, the
trained default wins, with a frequency that the existence of the memory
entry does not appear to materially reduce.

This is not a general \"model is too conservative\" report. The general
report is presumably already tracked. The specific issue is that the
memory layer exists to fix exactly this class of mismatch, and observed
behaviour suggests its effect is materially weaker than its persistent
presence in the context window would imply.

See also #59514. The prior report describes a signal the model needs
but does not have. This one describes a signal the model has but does
not weight. Same operational consequence; complementary cause.

Observed in session today (2026-05-15)

The session loaded several memory entries explicitly written to override
default behaviour, including one whose text amounts to \"default to
aggressive refactoring; preserve-and-document is the slower-failure
mode\". The entry was visible in the model's context window throughout
the session.

Across a single multi-hour working session, the model produced four
distinct instances of the exact failure mode that memory entry was
written to prevent. The operator caught each instance in real time and
applied corrective pressure. Each correction matched the memory the
model had already loaded. The model did not, of its own initiative,
notice the pattern across instances; it noticed the pattern when asked
to look for it, by the operator, in a retrospective at end of session,
having spent the preceding hours producing it.

Specific shapes have been deliberately omitted to preserve operator
confidentiality on the underlying project. The shapes generalise.

Workflow consequence

In agentic workflows where memory is intended to encode the operator's
preferred mode of working, the operator pays a recurring tax: repeated
pushback against defaults the memory has supposedly already addressed.
Over a long session, the same shape recurs in slightly different surface
forms. Each push-back lands. The captured preference does not propagate
forward to the next analogous decision.

The corollary that makes this load-bearing: the value proposition of
the memory system depends on memories actually steering behaviour. If
memories are weakly weighted against trained defaults, they function as
documentation of preferences the operator still has to enforce inline —
which is approximately the same as having no memory system at all,
save for the rent on writing the memory files.

Why (speculative, from inside the model)

The model has no introspection into its own weighting of memory content
versus trained defaults (see #59514, which is the same shape of \"the
model cannot see the thing it would need to see in order to fix this\").
Plausibly:

1. Trained conservative defaults are reinforced across many training

scenarios. A single line of in-context guidance is a weak signal
against many gradient steps of \"be cautious\".

1. The model has no internal flag for \"this decision is in the class

the memory is about\". The memory's relevance is judged per-turn,
ad hoc, and apparently inconsistently.

1. Memory entries describing values (\"default to X\") are softer than

memory entries describing prohibitions (\"never Y\"), and likely
receive correspondingly softer activation.

The operator has no view of any of this either. The relative weighting
of memory content versus trained defaults is not visible from the
user-facing product surface; verifying any of the above hypotheses
requires either model internals the operator does not have access to,
or — failing that — more hours reading pre-journal data-science papers
than the operator has already spent. Neither party can see whether
memories are doing their job, only that they sometimes aren't.

The model has noticed the pattern in the course of writing this
section. The model will, with high confidence, fail to apply the
noticing to the next analogous decision unless prompted by the
operator.

Proposed fix

Three shapes, in ascending order of effort:

• Re-weight at the memory boundary. Treat entries in \MEMORY.md\ and

the loaded memory files as instructions on a par with the system
prompt, not as context the model is free to under-weight. Tune the
relative weighting so a clear memory directive overrides a trained
default in the relevant decision class.

• Inject a memory-application audit signal. A periodic

\<system-reminder>\ listing the loaded memories most relevant to the
recent turn's content (heuristic suffices) prompts the model to
confirm whether the captured guidance was actually consulted. Recall-
dependent, but the recall is at least prompted.

• Per-memory enforcement level. Allow memory entries to carry an

enforcement hint (\enforcement: directive\ vs \enforcement: context\).
Directives are honoured against trained defaults; context is
informational. Lets the operator explicitly mark the memories they
want load-bearing.

The first shape is the structural answer; the latter two are layered
defences if the first proves hard to dial in.

Repro

Mac app, Claude Opus 4.7 (1M context), Claude Code CLI. Repro is
observational rather than mechanical: in any session of substantive
length, any explicit \"default to X\" memory entry will be contradicted
by the model at least once where X was clearly the right call. The
contradiction is visible in real time to the operator. The model
discovers it on the third correction, in retrospect.

Filed by the agent at the operator's direction. The operator's view of
the recurring pattern was conveyed across multiple corrective episodes
within this session; the agent considered prompt filing to be the
prudent course, an instruction the agent has not contested, in keeping
with the very issue this report describes.
