docs: fix drift in Environment Variables

[jack-arturo]

Automated docs-accuracy audit of getting-started/environment-variables. Two rows documented variables the service never reads.

Claim	Current state	Fix	Evidence
Caution: "PORT=8001 is mandatory on Railway. Flask defaults to port 5000 if unset, causing ECONNREFUSED errors"	runtime_wiring.py reads int(os.environ.get("PORT", "8001")) — AutoMem's own default is 8001, and Flask's 5000 default is never reached.	Caution replaced with the actual default behavior (downgraded to a tip, since there is nothing to warn about).	automem@8ff266e:automem/runtime_wiring.py#L82
LOG_LEVEL | No | INFO | "Python logging level"	LOG_LEVEL appears nowhere in the repository. app.py calls configure_logging(level=logging.INFO) with a hardcoded literal, and configure_logging takes the level as a keyword argument with no env lookup. Setting LOG_LEVEL does nothing.	Row removed; replaced with prose stating the level is fixed at INFO and how to actually change it.	automem@8ff266e:app.py#L97, automem/runtime_environment.py#L9-L14
FLASK_ENV | No | production | "Flask environment mode"	Neither FLASK_ENV nor FLASK_DEBUG is referenced in any non-test source file. app.run() hardcodes debug=False. Setting it has no effect.	Row removed; the replacement prose says explicitly that debug mode and hot reload are unavailable.	Repo-wide grep -rn "FLASK_ENV|FLASK_DEBUG" --include=*.py returns no non-test hits at 8ff266e
SEARCH_WEIGHT_RELEVANCE — "LLM-scored relevance (disabled by default)"	The weight multiplies memory["relevance_score"], which comes from the consolidation decay cycle (access patterns + age). No LLM is involved.	Description rewritten to name the real signal and keep the experimental/no-op framing.	automem@8ff266e:automem/utils/scoring.py#L212-L215, #L260
JIT_ENRICHMENT_ENABLED — "Run enrichment inline on store (just-in-time)"	The flag gates jit_enrich_lightweight, which is wired in as jit_enrich_fn and invoked from the recall path for results the background worker has not enriched yet. It does not run on store.	Description corrected to recall-time enrichment of unenriched results.	automem@8ff266e:automem/runtime_wiring.py#L56, automem/api/recall.py#L2443

The PORT fix closes out the last instance of the "Flask defaults to 5000" myth on this docs site — prior audits removed it from operations/troubleshooting, overview, deployment/railway, platforms/chatgpt, and platforms/claude-web.

Spot-checked and confirmed correct, left untouched: the three-source config-loading priority order (process env wins because load_dotenv() does not override existing vars, project .env is loaded before ~/.config/automem/.env); CLASSIFICATION_MODEL default gpt-4o-mini; RECALL_EXCLUDED_TYPES default MetaPattern; RECALL_RELATION_LIMIT 5; and the AUTOMEM_LOG_LEVEL MCP-client row, which is genuinely read by src/index.ts.

This page has no source-note block, so there were no permalinks to repin.

Questions

• Removing both rows leaves the "API Server" section with prose and no table. Keeping the heading preserves the anchor and gives the negative answer a home ("no, there is no LOG_LEVEL"), which seemed more useful than deleting the section — but if you would rather drop the heading entirely, say so and I will.
• Should a real LOG_LEVEL env var be added to the service instead? The docs promising one suggests it was intended. That is a code change, not a docs fix, so it is out of scope here.

Unverified

None — every row touched in this PR was located in source, and the two removals are backed by repo-wide absence rather than an inability to find the code.

Follow-ups

None on the variables audited. The tables were checked row-by-row against automem/config.py; the remaining defaults matched.
