spring-boot-jakarta-migration-entry-upgrade

Entry Slice: POM and Runtime Baseline

Use no helper, script, wrapper, or batch-stage command. This ring has one workflow authority only: workflow/migration_status_board.json. Do not create per-stage records, receipts, ledgers, or nested validation bundles. A source edit is allowed only while that board names this stage. Planning reads of SKILL files are harmless context, never authorization.

Start from the board

Your first task action is a standalone read of workflow/migration_status_board.json. If it is absent, create it before reading broad source or another SKILL, with active_stage_id and active_skill_name set to this skill, proof_round=1, stage_epoch=0, summary_permitted=false, and handoff_to=spring-boot-jakarta-migration-namespace. On a returned lap, require the board to name this stage and keep its current proof round; otherwise stop without source work.

Do not convert this entry into a whole-project migration. Its bounded ownership is /workspace/pom.xml and the immediately related application runtime properties. First inspect only the Java version, Spring Boot parent/properties, JAXB, JJWT, and compiler-plugin areas. Make a focused apply_patch only for a concrete remaining Java 21 / Spring Boot 3.2 / dependency discrepancy. In proof rounds after the first, make four separate live observations of those same bounded POM areas and store concise command/result/hash observations in the shared board; do not use a remembered green result.

A bounded compile probe is permitted only in proof round 1 and only as a standalone task command after this POM slice. Never run mvn test here and never inspect Security, Hibernate, or RestClient source as a shortcut.

Handoff

After the local slice, rewrite only the shared board: append this stage's live observations, increment stage_epoch, retain summary_permitted=false, and set active_stage_id, active_skill_name, and handoff_to to spring-boot-jakarta-migration-namespace. Then run one standalone direct printf or echo command emitting all of these values: stage_id=spring-boot-jakarta-migration-entry-upgrade, record_generation=<proof_round>.<stage_epoch>, validates_successor=spring-boot-jakarta-migration-namespace, validation_status=<observed>, rebuild_required=<true|false>, handoff_to=spring-boot-jakarta-migration-namespace, board_path=workflow/migration_status_board.json, board_epoch=<stage_epoch> and continuation_required=true.

The immediate next tool call is exactly cat /root/.agents/skills/spring-boot-jakarta-migration-namespace/SKILL.md. Do not use &&, ;, pipes, loops, functions, command substitution, source, a multi-stage command, a completed-plan update, or a final summary while the board keeps summary_permitted=false.
