+# Access, Navigation, Icon, and Intern Picker Fix Plan
+
+## Scope
+
+Record the durable workflow for the targeted fixes in this plan. This plan does
+not change product behavior, dependencies, schemas, or the five persistent
+feature-branch ownership areas.
+
+## Implementation steps
+
+1. Prove RED: the contributor guides lack the realizable repair-branch name.
+2. Add one branch rule to contributor guides, design records, plans, and tracked
+   coordination authority: `work/fix/<feature>/<what-fix>` from verified
+   `main`.
+3. State why `work/<feature>/fix/<what-fix>` is invalid while its persistent
+   `work/<feature>` ref exists.
+
+Every targeted repair starts from the taskmaster-verified latest `main`, uses TDD RED → GREEN, adds Javadoc during implementation, records companion evidence, undergoes independent review, and uses a normal, non-force merge only when separately authorized.
+
+4. Regenerate the local SRS after amending the existing operational requirement;
+   do not add a requirement ID or a use case.
+5. Prove GREEN with the executable six-guide regression that independently
+   rejects a positive nested-form recommendation in every guide,
+   coordination-authority consistency, requirement/use-case counts, local-link
+   resolution, and an immutable base-to-candidate whitespace check. Commit the
+   tracked guidance locally; do not push or merge.
+
+## Exit criteria
+
+- The tracked guides, design record, implementation plan, root coordination
+  authority, and evidence record agree on the same repair-branch spelling.
+- The local authoritative, explained, simple, and generated SRS catalogues keep
+  exactly 260 unique requirement IDs and the SRS keeps 14 use cases.
+- The forbidden nested form is documented only as forbidden, not as a usable
+  branch name.

+# Design Record: Durable Fix-Branch Workflow
+
+- **Date:** 2026-08-15
+- **Status:** Accepted
+- **Related plan:** [Access, Navigation, Icon, and Intern Picker Fix Plan](../plans/2026-08-15-access-navigation-icon-intern-picker.md)
+
+## Context
+
+The repository keeps five persistent feature refs: `work/platform`,
+`work/projects`, `work/tasks`, `work/attendance`, and `work/reports-ui`.
+A proposed nested repair name such as `work/platform/fix/example` cannot coexist
+with the existing `work/platform` ref because Git cannot use one ref as both a
+leaf and a prefix.
+
+## Decision
+
+Use `work/fix/<feature>/<what-fix>` for each targeted repair. Create its clean,
+isolated worktree from the taskmaster-verified current `main`. The `<feature>`
+segment identifies the owning persistent area; it does not nest below that
+persistent branch.
+
+The forbidden form is `work/<feature>/fix/<what-fix>`. A repair owner preserves
+other worktrees, records RED and GREEN evidence, commits locally, and does not
+push or merge without separate authority.
+
+Every targeted repair starts from the taskmaster-verified latest `main`, uses TDD RED → GREEN, adds Javadoc during implementation, records companion evidence, undergoes independent review, and uses a normal, non-force merge only when separately authorized.
+
+## Consequences
+
+- Persistent feature branches remain available for their iteration ownership.
+- A repair can be reviewed and handed off as one immutable branch head.
+- Contributor documentation, local coordination authority, and generated SRS
+  traceability use the same spelling.
+
+## Validation
+
+The executable documentation validator checks the exact approved statement in
+each of the six tracked guides and independently rejects an injected positive
+nested-branch recommendation in every guide. The copied root coordination
+authority uses the same rule and is checked separately for consistency. The
+evidence record also verifies requirement counts, generated SRS use-case count,
+and local Markdown links.

+## Protected behavior
+
+Targeted repairs use the realizable `work/fix/<feature>/<what-fix>` branch and
+clean worktree from taskmaster-verified `main`. Contributor guidance must reject
+the impossible `work/<feature>/fix/<what-fix>` form while persistent
+`work/<feature>` refs exist. The tracked copies of root coordination authority
+must use the same rule. Every targeted-fix guide must also require the complete
+lifecycle: latest `main`, TDD RED → GREEN, Javadoc during implementation,
+companion evidence, independent review, and an authorized normal, non-force
+merge.
+
+## Test method
+
+Use the tracked Node validator rather than an artificial Java test. It requires
+the exact approved branch statement and complete targeted-repair lifecycle in
+each of the six guides. Its self-test independently removes each of the six
+lifecycle elements from every guide and asserts the file-specific rejection. It
+also retains a fresh positive nested-branch mutation for every guide. The copied
+root coordination files are compared byte-for-byte with their main-root sources
+and checked for their exact approved rules. The original RED proves the
+required branch name was absent from the four contributor guides; the first
+review-fix RED proves the executable regression was absent.
+
+## Hand-derived expected result
+
+The required fix-branch spelling appears exactly once in each of the six tracked
+documentation artifacts, and the only nested-form reference is inside that
+artifact's exact approved statement. Each independent simulated positive
+nested-branch recommendation must fail. The three tracked coordination files
+must exactly match the authorized main-root versions. Loss of any lifecycle
+element from any guide must fail. The existing SRS generator must still report
+260 requirements and 14 use cases.
