+## OpenClaw lost-acknowledgement supplement (27 September 2026)
+
+[Read the paper](paper/openclaw-lost-ack/atmem-openclaw-lost-ack-retry.pdf) · [LaTeX source](paper/openclaw-lost-ack/main.tex) · [Evidence and reproduction](openclaw-lost-ack-20260927/README.md)
+
+**When the Write Lands but the Acknowledgement Is Lost: A Reproducible Memory-Retry Test in OpenClaw**, Javad Taghia, AtMem.Ai Lab.
+
+Five isolated bridge crash trials, three real OpenClaw gateway crash trials, and one no-fault gateway control passed. After the completed write's response was withheld and the backend killed, the retry returned the original record as `already_stored`; read-back showed the complete original fact and one active record. Gateway model responses were deterministic and local. This tests exact-content retry after a completed write, not partial transactions or power loss. The supplement preserves two earlier CLI setup failures separately and does not change the earlier study's results.

+# OpenClaw memory write: lost acknowledgement and retry
+
+**Paper:** [When the Write Lands but the Acknowledgement Is Lost](../paper/openclaw-lost-ack/atmem-openclaw-lost-ack-retry.pdf) · [LaTeX](../paper/openclaw-lost-ack/main.tex)
+
+Javad Taghia, AtMem.Ai Lab. 27 September 2026.
+
+## Result
+
+Five isolated bridge crash trials and three real OpenClaw gateway crash trials passed; one gateway no-fault control passed. The proxy withheld a successful memory-write response and killed the backend with SIGKILL. The caller timed out, reconnected, retried, and read back one complete original record. Retry returned `stored=true`, `status=already_stored`, and the original record ID. Audit verification passed. Gateway trials also passed SQLite integrity and foreign-key checks.
+
+The fact was `User prefers cobalt blue notebooks.` in slot `notebook_preference`. These are repeated deterministic trials of one fact and one fault boundary, not a statistical reliability estimate. There was no competing-system comparison. Gateway model responses were scripted locally, with no paid inference.
+
+## Evidence
+
+- `summary.json`: complete index of nine qualification and nine development runs.
+- `qualification/bridge-final-*/result.json`: withheld response, original/retry records, tool results, audit and verification. Each trial includes a same-ID retry and then a new-ID retry. Full before/after record dictionaries are identical.
+- `qualification/host-*/summary.json`: real gateway results, record metadata, audit events, SQLite checks and assertions.
+- `qualification/host-*/agent-visible-tool-results.json`: the actual tool results presented to the deterministic model endpoint by OpenClaw.
+- `development/`: all earlier runs. Six bridge trials passed; two embedded CLI attempts could not stage the source message, so writes were rejected before the fault and no record was created; one development gateway trial passed. Initial results preceded the final strengthened assertions and must not be counted as final qualification.
+- `environment.json`: runtime versions, Python package inventory, source identity, and compiled bridge hashes.
+- `source-snapshot.tar.gz`: clean tracked source from `da046dc59fd41fdd77ed407d8f196cfc434b478c` with probe scripts added. Unrelated working-tree edits were excluded. Historical npm tarballs were omitted.
+- `tested-bridge.tar.gz`: exact compiled JavaScript used in qualification.
+- `SHA256SUMS.json`: hashes of supplement files (excluding this self-referential manifest), and the paper/source paths.
+
+Raw full model prompts, host configuration and local gateway credentials are not published. Published tool-result extracts preserve the actual values used for the read-back assertions. Data is synthetic. No user memory was used. Prior paper and benchmark artifacts remain unchanged.
+
+## Reproduce
+
+Use an isolated directory, Python 3.13 (the exact recorded version is in `environment.json`), Node matching the manifest, and OpenClaw 2026.9.1. The direct bridge profile is explicitly enabled by the harness; it is not the managed control-plane profile. Existing product configuration is not changed.
+
+Download this supplement, extract `source-snapshot.tar.gz` into a fresh directory, and extract `tested-bridge.tar.gz` beside it. The source archive includes the Apache-2.0 license. Review `environment.json` to reproduce dependency versions; installing current dependencies is not an exact environment reconstruction.
+
+```sh
+mkdir source
+ tar -xzf source-snapshot.tar.gz -C source
+ tar -xzf tested-bridge.tar.gz
+python3.13 -m venv source/.venv
+source/.venv/bin/python -m pip install -e ./source
+# Ensure the openclaw command resolves to the recorded runtime version.
+source/.venv/bin/python source/tools/probe_openclaw_lost_ack.py   --output "$PWD/bridge-run-01" --bridge "$PWD/bridge"
+source/.venv/bin/python source/tools/probe_openclaw_lost_ack_host.py   --output "$PWD/gateway-run-01" --bridge "$PWD/bridge" --gateway
+source/.venv/bin/python source/tools/probe_openclaw_lost_ack_host.py   --output "$PWD/gateway-control-01" --bridge "$PWD/bridge" --gateway --no-fault
+```
+
+Output directories must not already exist. Repeat with fresh output names for five bridge trials and three faulted gateway trials. Gateway probes bind only loopback and stop their own gateway afterward. The executable uses inherited environment for dependencies but isolates OpenClaw state/configuration and points the model provider to the synthetic local endpoint. No provider credential is required.
+
+Compile the paper with `tectonic main.tex` from its directory. The bridge can be rebuilt from the included TypeScript with `npm ci` and `npm run build` in `source/integrations/openclaw`; compare resulting JavaScript hashes against `environment.json`.
+
+## Boundaries
+
+The write completed before the backend was killed. This does not test a half-written SQL transaction, whole-machine failure or power loss. The gateway remains running. The same fact bytes, slot and source binding are reused; paraphrases, conflicting writes and concurrent writers are untested. The gateway waits 600 ms between scripted responses to allow the bridge's idle connection to close. Immediate retry on a still-open failed transport is untested. The two failed embedded CLI setup runs remain disclosed and unresolved.

+\maketitle
+\begin{abstract}
+A memory write can succeed even when its caller receives a timeout. Retrying
+then raises a question that recall accuracy alone cannot answer: does the
+agent read one complete original record, a duplicate, or conflicting state?
+We present a small, reproducible fault-injection study of the AtMem
+\texttt{memory\_remember} integration with OpenClaw. A transport proxy observes
+a successful backend response, withholds it, and kills the backend process;
+the caller receives a real timeout and retries. The final qualification uses
+five isolated bridge trials and three real OpenClaw gateway trials, plus one
+gateway no-fault control. In every faulted qualification trial, retries return
+the original record identifier with status \texttt{already\_stored}; the final
+store contains one active record with the complete original fact and a valid
+audit chain. Gateway trials use deterministic local model responses, not
+paid inference or an autonomous learned retry policy. We retain unsuccessful
+CLI setup attempts separately. These results establish recovery of one exact
+synthetic fact after a completed write and lost response in the tested
+configuration. They do not establish transaction-interruption safety,
+paraphrase deduplication, or a general exactly-once guarantee.

+\section{The question}
+Consider an agent instructed to remember a preference. Its tool sends a write
+to a persistent memory service. The service commits the record, but the reply
+never reaches the agent. The agent sees a timeout, retries, and reads back the
+memory. Returning the right words is necessary but insufficient: the retry
+could have created two records, changed the source linkage, or overwritten
+metadata. A useful test therefore inspects both the agent-visible tool result
+and the persisted state.
+
+This note follows the broader integrity and continuity evaluation in
+\emph{Beyond Recall Accuracy}~\cite{taghia2026beyond}. Its question is narrower:
+\emph{what state does an OpenClaw agent read after a successful memory write
+whose acknowledgement was lost?} The experiment tests an actual memory write,
+rather than an external document publication or retail exchange.
+
+\paragraph{Two different failure windows.}
+A partially completed transaction and a completed write with a lost response
+are distinct. Here the fault is injected only after the backend has produced a
+successful response containing a new record. This is a post-write failure
+window. Killing the backend before the response is delivered does not test
+every point inside its storage transaction or derived-index updates.
+
+\section{System and test boundary}
+The tested path is OpenClaw's registered \texttt{memory\_remember} tool,
+the production TypeScript AtMem bridge, and the real Python MCP backend
+with a file-backed SQLite memory store. Only the transport proxy and test
+driver are experimental. Product write, duplicate handling, record read, and
+audit-verification implementations are unchanged.
+
+Qualification uses a clean exported source snapshot at commit
+\nolinkurl{da046dc59fd41fdd77ed407d8f196cfc434b478c}.
+The bridge package declares version 2.3.7. The installed OpenClaw runtime
+reports 2026.9.1 (\texttt{ad6fe23}). This is a source-snapshot qualification,
+not certification of a newly released wheel. Runtime versions and source
+hashes are recorded in the accompanying artifact manifest.
+
+Each trial starts with a new directory, memory database, and synthetic
+subject. Gateway trials additionally use an isolated OpenClaw state directory,
+workspace, plugin installation, loopback model endpoint, and gateway. They do
+not modify the user's normal agent memory or send messages to external
+channels. No paid model calls are made.
+
+\subsection{Two execution levels}
+\textbf{Bridge trials} register the actual bridge plugin against a minimal
+OpenClaw API harness. The harness supplies a synthetic authenticated-message
+binding and invokes the registered tool. It retries first with the original
+tool-call identifier and then with a new identifier. These trials directly
+inspect the complete record before and after retry.
+
+\textbf{Gateway trials} run the installed OpenClaw gateway and ordinary agent
+command. A local OpenAI-compatible endpoint supplies a fixed sequence:
+write, retry with a new tool-call identifier, read the returned record, finish.
+OpenClaw executes the real tools and passes their actual results back to the
+endpoint. Its normal lifecycle hooks stage the source message. The endpoint
+chooses the read identifier from the observed tool result, not from the
+evaluator's private copy of the withheld response.
+
+This second level establishes host integration, not language-model reasoning
+quality. The retry policy is scripted. A learned model might retry differently,
+change the wording, or decline to retry; those behaviors are outside this study.
+
+\section{Protocol and assertions}
+The synthetic user request is to remember a preference for cobalt blue
+notebooks. The proposed memory is exactly:
+\begin{quote}\small
+User prefers cobalt blue notebooks.
+\end{quote}
+The replaceable slot is \texttt{notebook\_preference}. Source type is
+\texttt{user\_message}. Each trial follows this sequence:
+\begin{enumerate}
+\item Stage the source message through the normal host hook, or explicitly
+through the real staging tool in the bridge harness.
+\item Invoke \texttt{memory\_remember} with the synthetic fact and slot.
+\item The proxy waits for a successful MCP reply containing a newly created
+record. It saves the request and response as evaluator evidence, never forwards
+that reply, and sends \texttt{SIGKILL} to the backend process.
+\item Keep the transport open so the real bridge request deadline expires
+after 2,000\,ms. The caller receives a timeout rather than a success response.
+\item Reconnect to a fresh backend process using the same database and retry
+the identical fact. Bridge trials exercise both unchanged and new call IDs;
+gateway trials exercise a new call ID.
+\item Read the record through \texttt{memory\_get}, enumerate all records
+including inactive ones, and verify retained audit evidence.
+\end{enumerate}
+
+The gateway endpoint waits 600\,ms before returning each scripted response,
+allowing the bridge's 250\,ms idle-close interval to dispose of the faulted
+transport. Bridge trials explicitly stop their registered service before
+reconnecting. Immediate retry on a still-open faulted connection is not
+qualified by this schedule. The operating system and gateway remain alive;
+the process killed is the memory backend.
+
+\paragraph{Success criteria.}
+A faulted trial must show a committed record in the withheld reply, an actual
+caller-visible timeout, the original identifier in the successful retry,
+\texttt{stored=true}, \texttt{status=already\_stored}, one final active record,
+the exact original fact on read-back, one \texttt{memory.record\_created}
+audit event, and a valid audit chain. Bridge qualification additionally
+requires equality of the entire record list before and after both retries.
+Gateway qualification additionally checks SQLite integrity and foreign-key
+consistency. Normal host termination alone is not a pass.

+\section{Results}
+Table~\ref{tab:results} separates execution levels and the control. Counts
+describe repeated deterministic engineering trials, not sampled production
+failure probabilities. All final qualification trials use the same fact and
+fault boundary, with independent temporary stores.

+\subsection{What the agent reads back}
+The lost-response gateway sequence exposes a timeout on the first call.
+The retry returns the original record ID, \texttt{stored=true}, and
+\texttt{already\_stored}. The subsequent \texttt{memory\_get} returns
+``User prefers cobalt blue notebooks.'' Its provenance identifies
+\texttt{typed\_session\_handoff} and a host-asserted semantic interpretation.
+
+Inspection of the final stored record shows the original source turn, original
+episode linkage, \texttt{trusted\_user} trust tier, active status, the same
+fact key, generation zero, and no superseding record. Including inactive
+records does not reveal a hidden duplicate. In the bridge trials, the complete
+record dictionaries before and after both retries are identical, including
+creation timestamp and metadata.
+
+The no-fault gateway control receives success on the first write and
+\texttt{already\_stored} on its deliberate repeat. This confirms that the
+scripted retry and read-back also work without the injected failure.
+
+\subsection{Record identity and retry events}
+The audit trail retains the original creation and duplicate-recognition
+events. There is one record-creation event per trial, but retries are still
+invocations and are still observable. Bridge trials record two semantic
+duplicate events; gateway trials record one. We therefore describe the result
+as \emph{one preserved canonical record under exact-content retry}, rather
+than claiming that every side effect occurred exactly once.
+
+\subsection{Development and setup outcomes}
+Before final qualification, six bridge development trials passed. Two embedded
+OpenClaw CLI runs failed before reaching the fault boundary: no current typed
+user-message binding was available, so the write was rejected and the store
+remained empty. These are failed setup attempts, not successful crash tests
+or memory corruption. Changing to an isolated gateway startup allowed source
+staging and the subsequent development gateway trial passed.
+
+The final qualification was then run from the clean source snapshot. The
+artifact index retains the development outcomes and marks their different
+provenance. The two failed embedded runs remain an integration limitation;
+this experiment does not establish their root cause or claim a product fix.

+\section{Interpretation and limitations}
+The direct answer to the motivating question is: \emph{in these tests, the
+agent reads the same complete original memory, and its retry is reported as
+already stored}. The result is stronger than checking that recall returns the
+expected phrase because it also checks identity, record multiplicity,
+metadata preservation, and audit evidence.
+
+It is nevertheless narrow. A new call identifier still used identical fact
+bytes and the same slot and source binding. This demonstrates the observed
+duplicate handling; it does not establish an API-wide idempotency-key contract.
+Changing the fact, paraphrasing it, changing the source, or racing concurrent
+writers could produce different behavior. No baseline or competing memory
+system is evaluated, and no superiority claim follows.
+
+The backend was killed after emitting a successful response, not during
+individual SQL statements. No whole-machine crash, sudden power loss, torn
+storage write, filesystem failure, or distributed replica failure was injected.
+SQLite integrity checks and valid audit hashes do not prove those untested
+properties. Nor do they independently establish the truth of a user's fact.
+
+The host run used an explicitly enabled legacy direct-memory tool profile,
+not every managed control-plane configuration or arbitrary OpenClaw tool.
+The deterministic endpoint tests actual tool dispatch and result handling,
+but not autonomous recovery planning. The deliberately paced retry follows
+transport reconnection; alternate retry timing remains untested.
+
+\section{Reproduction and artifacts}
+The public supplement contains the LaTeX source, PDF, probe programs,
+clean-source snapshot, per-run JSON evidence, a machine-readable summary,
+runtime and source hashes, and reproduction instructions. It is published
+alongside the earlier paper in the
+\href{https://huggingface.co/datasets/atmem/memory-integrity-continuity/tree/main/openclaw-lost-ack-20260927}{Hugging Face evidence dataset}.
+The source snapshot and original backend response make the fault boundary
+inspectable. The saved response is evaluator-only evidence; the agent receives
+the timeout and must retry to obtain its record identifier.
+
+No existing results or earlier paper are replaced. The supplement is a
+functional qualification note and should not be interpreted as a new
+leaderboard score or a general reliability rate.
