Record game runtime, framework/DLL version, log filename, timestamp, and the exact deployed file that generated the line.
Preserve the complete diagnostic line and enough neighboring context.
Identify the parser stage or subsystem that emitted the message.
Parse the affected configuration by fields. Never diagnose delimiters using a whole-line grep.
Separate:
- syntax rejection;
- unresolved form or dependency;
- optional rule skipped;
- feature disabled;
- safe hook abort;
- deterministic conflict winner;
- missing asset;
- ordinary informational noise.
Prove the root cause against installed source/docs or matching upstream source before mass-editing.
Make the smallest reversible correction in the owning mod's source/output, redeploy, and compare the new log.
Do not delete or edit active Data directly. Fix the owning mod or generated output and redeploy through the mod manager.

High-risk interpretation rules

SPID

Unsupported form type Weapon means the distribution key is unsupported. For distributing a weapon or staff, current SPID uses Item or the generic Form key, not Weapon.
invalid stoul argument is not enough to blame Traits or Chance. Inspect the field position. A LevelFilters value such as 65/ has an empty range endpoint and is malformed.
-D is a valid starts-dead trait exclusion.
A trailing ! on Chance, such as 18!, is valid deterministic chance.
More than seven pipe-separated value sections is invalid.
Comma-separated TraitFilters are invalid; slash-separated traits are correct.

Native hooks

An address outside the expected executable .text section proves that the candidate hook target is invalid for that installation. It does not prove which other DLL, relocation, vtable layout, or runtime mismatch caused it. Require module ownership, relocation/vtable index, runtime version, target bytes, and section bounds before naming a culprit. A safe abort is preferable to installing an unverified hook.

Community Shaders

<Feature>.ini failed to load, feature disabled means the feature's own descriptor was not loaded. For the current integrated architecture, descriptors are sought under:

Data\Shaders\Features\<FeatureShortName>.ini

A preset override cannot make an unloaded feature operational. Inspect winning files and feature versions rather than assuming the preset installed the feature.

Missing animations

A missing .hkx is not repaired by an A-pose suppressor. Resolve the animation path to its owning behavior graph and source mod. A behavior generator can regenerate supported behavior output, but it cannot invent an absent custom creature animation.

BOS

The last config alphabetically wins conflicts, but a deterministic winner is not proof that the winning transform belongs to the affected reference/worldspace. Inspect the specific reference, section, conditions, and intended patch. Transform tokens such as rotR(x,y,z) must remain one token.

Missing forms and dependencies

Classify each unresolved form as hard requirement, conditional requirement, optional integration, or stale configuration. Do not claim a missing optional plugin breaks the entire framework. Do not auto-delete a config until its owner and intended feature are known.

Read references/LOG-CASEBOOK.md. Run scripts/analyze_runtime_logs.py for a conservative first pass, then inspect every reported row manually.
