Review

Findings

Low

• [naming-convention] fedora-ci/jobs.md:17 — The heading ### installability uses all-lowercase, diverging from the sentence-case convention used in higher-level headings (e.g., ## Scratch builds). However, within the ## Tests section, the pre-existing headings ### rpmlint and ### rpminspect already used lowercase as canonical tool names. This PR normalizes installability to match its siblings and the exact CLI identifier used in /packit-ci test installability — a defensible editorial choice.

• [naming-convention] fedora-ci/jobs.md:43 — The heading ### custom test plans uses all-lowercase, changed from the previous ### Custom test plans. Unlike the tool-name headings, "custom test plans" is a descriptive phrase rather than a canonical identifier, so the case for sentence-case capitalization is stronger. Consider restoring ### Custom test plans if the project prefers sentence case for descriptive headings, or keep it lowercase if the intent is uniform casing across all test sub-headings.

[low] naming-convention

The heading ### installability uses all-lowercase, diverging from the sentence-case convention used in higher-level headings (e.g., ## Scratch builds). However, within the ## Tests section, the pre-existing headings ### rpmlint and ### rpminspect already used lowercase as canonical tool names. This PR normalizes installability to match its siblings and the exact CLI identifier used in /packit-ci test installability — a defensible editorial choice.

Suggested fix: If the project prefers sentence case for all headings, change to ### Installability. Otherwise, the current lowercase is consistent with sibling test headings.

[low] naming-convention

The heading ### custom test plans uses all-lowercase, changed from the previous ### Custom test plans. Unlike tool-name headings (rpmlint, rpminspect, installability), 'custom test plans' is a descriptive phrase rather than a canonical tool identifier, so the case for keeping it capitalized is stronger. The PR is establishing a uniform lowercase style for all test sub-headings to match their CLI identifiers.

Suggested fix: Consider restoring to ### Custom test plans since this is a descriptive phrase, not a tool name. Alternatively, if the project decides all test headings should match their CLI identifiers, the lowercase is acceptable.
