Read dev/issues/*.md and dev/flows/*.md as kanban cards via new
/api/boards/{issues|flows}/cards endpoints. PATCH writes status back
to the frontmatter atomically (tmp + rename), POST .../launch proxies
to agent_runner_api.
- issues_source.go: scan + parse frontmatter (yaml.v3) into IssueCard.
Skips README/INDEX/AGENT_GUIDE. Malformed YAML yields parse-error
cards (no crash). Description = first 5 body lines (no full body).
- flows_source.go: same shape, distinct status->column mapping
(pending/running/done/deferred -> Pending/Running/Done/Deferred).
- frontmatter_edit.go: PatchFrontmatterField — atomic, preserves the
rest of the file byte-for-byte, inserts key if missing.
- handlers_boards.go: list + patch + launch endpoints, taxonomy 0103
enforced. Cache 30s in memory, thread-safe (mutex), invalidated on
PATCH. Launch returns 502 with suggestion when runner is down.
- main.go: SkipPaths += "/api/boards/" so the C++ frontend hits the
read endpoints without a kanban_web session.
Smoke (FN_REGISTRY_ROOT pointed at the worktree, 87 issues + 9 flows
on disk):
GET /api/boards/issues/cards -> 200, 87 cards
GET /api/boards/flows/cards -> 200, 9 cards
PATCH /api/boards/issues/cards/0119 {status:en-curso} -> 200,
file mtime changes, frontmatter rewritten, rest preserved
POST /api/boards/issues/cards/0119/launch -> 502
agent_runner_unreachable (expected, runner not yet implemented)
Tests: issues_source_test (3 cases incl. malformed + missing status),
flows_source_test (3 cases), frontmatter_edit_test (4 cases incl.
atomic rename + no tmp leftovers). Pre-existing tools_test failure
on TestExecuteTool_MoveCard_BetweenColumns_OpensHistory is unrelated
(CardHistoryResponse type assert, not touched here).
