# Assimilation — OrwellLoggingDiagnostics
**Status:** Decided. Canon placement is pending under INFO-WP-0030.
**Disposition:** Adapt
**Source:** coordination-engine candidate
`docs/orwell-logging-diagnostics-candidate.md` at `628f984`, preserved
under `source/`
**Authority:** `INFO-DEC-2026-003`, canon owner decision of 2026-09-22
**Consumer follow-up:** coordination-engine `COORDINATION-WP-0004`
## Scope
The candidate proposes a practice for rare local debugging that needs fields
normal logging must omit, such as message bodies, credentials, and terminal
output. The capture is an explicit, per-invocation, non-production diagnostic
mode that writes to an owner-controlled private sink and is never projected
remotely. This assimilation covers the generic practice. TAMQ's `--orwell`
flag, its field list, and its sink location remain owned by tmux-amq.
## Findings
- **Not a duplicate.** The Observability Model owns `Log`, `LogRecord`,
`LogLevel` and `LogStream`, but states no rule separating verbosity from
disclosure. The Data and Security models own sensitive-data classification
and do not describe a controlled, temporary exception to omission. No
existing pattern covers the tension between diagnosability and
non-disclosure.
- **Pattern-shaped.** The candidate resolves a recurring tension with ordered
practice steps and evidence (the six verifications in its §6). That fits
`PracticePatternScheme`.
- **Known use is implemented, not intended.** tmux-amq `04de219` implements the
flag in `src/tamq/diagnostics.py` and `src/tamq/cli.py`, with
`tests/test_diagnostics.py`. That satisfies the scheme's rule that a
known use identifies what was observed. There is one known use, so the
lifecycle entry point is `candidate`.
- **Why adapt, not adopt.** The name and the `--orwell` flag are
consumer-specific. The canon form needs a generic name, the scheme's section
layout, and imports of the owning concepts instead of restated definitions.
The substance of the six practice points carries over.
## DecisionRecord — INFO-DEC-2026-003
### Context
coordination-engine prepared the candidate under COORDINATION-WP-0003-T04 and
transferred canon review to COORDINATION-WP-0004. That workplan cannot close
without an explicit owner disposition. The request had not reached this
repository through intake. It was raised with the owner directly on
2026-09-22.
### Decision
Adapt the candidate into a generic candidate-status practice pattern under
`infospace/patterns/`. It will have a neutral name, import Log/LogRecord,
data classification and environment concepts from their owners, and cite
tmux-amq as its known use. The Orwell name may remain as an alias in the
pattern's Known Uses.
### Consequences
- Canon placement, registration, and the canon version change are INFO-WP-0030
(stage 4 and 5). The assimilation closes when that workplan finishes.
- coordination-engine can record this disposition in COORDINATION-WP-0004-T01.
COORDINATION-WP-0004-T02 waits for the registered artifact ID from
INFO-WP-0030.
- This disposition does not authorize unsafe logging in any runtime. The
pattern describes a practice, and its adoption stays with each consumer.
