LCD palette rotation — Railspike debug log

2026-10-21T21:33:38Z — Step 2: Feature Description

Debug mode: enabled by the project-root marker for this new follow-up. No effort-study selection applies. Predecessor implementation is complete; feat/lcd-color-choices is not merged into main. Application code is unchanged and the new planning artifacts remain uncommitted.

Necessary/useful instructions

• Source: RAILSPIKE.md, Follow-up Cycles Before Merge. Contribution: Keeps the completed palette work intact while allowing the requested enhancement in the same release/branch with a distinct identity and fresh approvals. Suggestion: Retain.

• Source: step2_feature_description.md, core requirements and completion boundary. Contribution: Makes the otherwise ambiguous rotation entry explicit: rotation starts at Green, while dropdown selection restores the remembered palette. Covers direct palette selection, labels, persistence, and exit after Gray. Suggestion: Retain these outcome requirements.

• Source: RAILSPIKE.md, Enhancement Requests. Contribution: The predecessor summary now links the pending request to this follow-up without rewriting its completed stages. Suggestion: Retain the durable backlink.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

• Source: RAILSPIKE.md, Step 1 assessment and effort estimation. Reason: No approach comparison is needed, Step 1 is optional, and this follow-up is not selected for the effort study. Suggestion: Retain optional/conditional application.

Uncertain assessments

• Source: RAILSPIKE.md, follow-up approval boundary. Observation: The user asks to include this small enhancement in the current cycle/release; the workflow distinguishes completed cycles from release branches and still requires fresh approvals. Suggestion: Preserve that distinction while keeping the follow-up documents brief.

2026-10-22T05:12:43Z — One-shot implementation

The user explicitly requested “Please just add it as a one-shot,” overriding the fresh staged follow-up approvals. Implementation and verification are recorded in the predecessor summary's enhancement section; no additional step approval is pending.

Necessary/useful instructions

• Source: RAILSPIKE.md, Enhancement Requests. Contribution: The request, explicit process override, implementation behavior, verification, and existing baseline limitation remain durable without rewriting the completed original stages. Suggestion: Retain request tracking even when the user selects a one-shot process.

• Source: CONTRIBUTING.md, UI verification. Contribution: Real Chromium phone/desktop checks verify the full cycle, labels, dropdown behavior, persistence, and recovery. A targeted delayed-load regression verifies that a later dropdown selection cancels pending Green rotation for the same theme. Suggestion: Retain behavior-based verification.

Redundant/unnecessary instructions

No supported new findings.

Inapplicable instructions

• Source: RAILSPIKE.md, Follow-up Cycles Before Merge, staged approvals and planning commit. Reason: Explicit user one-shot authorization supersedes that process for this enhancement. Existing completed commits are preserved. Suggestion: Continue honoring user process overrides without requesting repeated approval.

Uncertain assessments

No new findings. Evidence is focused Chromium/theme coverage, with the previously recorded composer storage baseline; no full-suite or cross-browser claim is made.
