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.
