## Created Created by LocalTicketBackend create. --- ## Intake summary Existing Ticket is sufficiently specified and not a duplicate of another visible active Ticket. Intake classifies it as implementation_ready with needs_preflight=true because it changes durable Ticket frontmatter parsing and compatibility semantics. Risk flags: ticket-backend, yaml-parsing, compatibility, panel-regression. Scope is limited to YAML/null-aware Ticket item.md parsing, list/bool handling, preserving emitted format/doctor compatibility, and the workspace panel attention_required:null regression. Validation should include focused ticket parser tests, workspace_panel regression tests, cargo fmt --check, git diff --check, and relevant cargo test commands; final implementation should also consider the project-level nix build requirement. --- ## State changed Intake completed: requirements, acceptance criteria, non-goals, affected fields, and validation are explicit enough for Orchestrator routing. Human queueing remains required before implementation starts. --- ## State changed Ticket queued for Orchestrator routing. --- ## Decision Routing decision: preflight_needed Reason: - The Ticket is well scoped and urgent, but it changes durable Ticket frontmatter parsing and compatibility semantics. - Intake explicitly classified it as implementation-ready only with `needs_preflight=true`, with risk flags `ticket-backend`, `yaml-parsing`, `compatibility`, and `panel-regression` in the intake summary. - YAML/null-aware parsing affects nullable strings, lists, booleans, doctor compatibility, existing fixture behavior, and workspace panel action derivation; a short design boundary check should precede coder delegation. Evidence checked: - Ticket body requirements, candidate affected fields, non-goals, and acceptance criteria. - Intake summary and `ready -> queued` event. - Workspace state: `develop` has only this Ticket's queued item/thread modifications plus an unrelated untracked Ticket directory `20260607-224309-reduce-ticket-lifecycle-commit-noise`; no branch/worktree exists for this slug. - Visible Pods: intake peer for this Ticket is idle; no coder/reviewer Pods are active for this Ticket. Next action: - Run `ticket-preflight-workflow` before implementation delegation. - Preflight should decide the parsing boundary: whether to deserialize `item.md` frontmatter through `serde_yaml::Value`/typed helpers or a narrower YAML-compatible layer; how to preserve emitted format; how to represent quoted literal `"null"` versus YAML null; and which tests cover Ticket parser plus workspace panel regression. - Do not transition `queued -> inprogress`, create `.worktree/parse-ticket-frontmatter-as-yaml`, or spawn coder/reviewer Pods until preflight records implementation readiness. Escalate if: - Existing Ticket records rely on raw-string parsing semantics that conflict with YAML behavior. - Adding a YAML parser dependency has packaging/licensing implications not already acceptable for this crate graph. - Fixing panel action derivation requires broader Ticket workflow/action model changes beyond parsing correctness. --- ## Decision Preflight decision: implement a YAML-aware typed parsing layer for Ticket `item.md` frontmatter values, not a strict whole-frontmatter YAML deserialization/migration. Implementation boundary: - Keep `parse_item` responsible for splitting `---` frontmatter from Markdown body and preserving `raw_frontmatter: BTreeMap` for compatibility/debug surfaces. - Add `serde_yaml` to `crates/ticket` and parse each scalar value through helper functions rather than replacing the whole frontmatter parser. - Nullable string helpers must treat YAML null forms (`null`, `Null`, `NULL`, `~`, empty value) as `None`, while preserving quoted literal strings such as `"null"` as meaningful text where applicable. - List helpers should support YAML sequences for `labels` / `risk_flags` and preserve existing simple inline list behavior. - Boolean helpers should support YAML booleans and keep the existing tolerant `yes/no/1/0` behavior. - Do not redesign the Ticket schema, migrate records, or change emitted frontmatter formatting in this Ticket. Rationale: - Existing Ticket frontmatter is YAML-like but may contain unquoted string values that are safer to keep under tolerant field-level parsing than to force through strict whole-document YAML semantics. - The reported regression is caused by typed optional/list/bool interpretation, so the fix should target typed field extraction while preserving current storage/writer compatibility. Required tests: - `attention_required: null`, `~`, and empty value parse as `None`. - quoted `"null"` remains distinguishable from YAML null for optional string fields. - `labels` / `risk_flags` YAML sequences parse correctly. - `needs_preflight: true` parses as `Some(true)` and tolerant legacy bool forms still work. - Workspace panel regression: `workflow_state: intake` plus `attention_required: null` derives `Clarify`, not `Edit`. Validation target remains the Ticket acceptance criteria plus project packaging validation where implementation touches source/package dependencies. --- ## Decision Preflight decision revised by human direction: do not preserve the old raw-string/tolerant Ticket frontmatter parsing semantics. Intentionally remove that backward compatibility and migrate this project's existing `.yoi/tickets` records to the new strict YAML-compatible format as part of the implementation. Supersedes the previous preflight recommendation to keep a field-level tolerant compatibility layer. Updated implementation boundary: - Parse `item.md` frontmatter as real YAML data instead of the current raw `key: value` string map. - Introduce typed YAML deserialization/parsing for Ticket metadata and fail clearly on invalid frontmatter rather than silently preserving legacy raw-string behavior. - Add a repository-local migration for the existing `.yoi/tickets` records in this project so current records are valid under the new parser. - Preserve emitted frontmatter format only insofar as it is valid YAML; quote/normalize existing values where needed during migration. - Remove per-field ad-hoc `"null"` filtering and old tolerant list/string compatibility when it conflicts with YAML semantics. - Keep the Ticket schema scope focused; do not redesign Ticket lifecycle or panel action model. Updated tests/validation: - Parser tests should assert YAML null/list/bool semantics directly. - Tests should cover invalid frontmatter failure where appropriate instead of legacy fallback acceptance. - Workspace panel regression remains required: `workflow_state: intake` plus `attention_required: null` derives `Clarify`, not `Edit`. - Migration diff should include only the needed `.yoi/tickets` frontmatter normalization, not unrelated Ticket content rewrites. --- ## Decision Routing decision: implementation_ready Reason: - Preflight has now been recorded and revised by human direction. - The design boundary is explicit: replace raw-string/tolerant Ticket item frontmatter parsing with real YAML-compatible typed parsing, fail clearly on invalid frontmatter, and migrate this project's existing `.yoi/tickets` records to valid YAML where needed. - The scope is still bounded to Ticket metadata parsing/emission compatibility, project-local Ticket record normalization, and workspace panel regression coverage; lifecycle and panel action model redesign remain non-goals. Evidence checked: - Ticket body requirements and acceptance criteria. - Intake summary and previous routing decision. - Preflight decision at `2026-06-07T22:55:52Z` and human revision at `2026-06-07T22:57:35Z`. - Workspace state: no branch/worktree exists for this slug; unrelated untracked Ticket directories are present but do not alter the source tree or the child worktree branch point. - Visible Pods: intake peer is idle; no coder/reviewer Pods are active for this Ticket. IntentPacket: Intent: - Parse Ticket `item.md` frontmatter as real YAML-compatible typed metadata so YAML null/list/bool semantics work correctly, including workspace panel action derivation. Requirements: - Replace the current raw `key: value` string interpretation for Ticket item frontmatter with typed YAML parsing/deserialization. - Ensure YAML null values such as `null`, `~`, and empty nullable fields become `None` where the schema field is optional. - Preserve quoted string semantics: quoted `"null"` is a string, not null, when valid for that field. - Parse YAML sequences for list fields such as `labels` and `risk_flags`. - Parse YAML booleans directly; remove old tolerant raw-string compatibility where it conflicts with YAML semantics. - Fail clearly on invalid frontmatter instead of silently falling back to legacy raw-string behavior. - Migrate this repository's existing `.yoi/tickets` records so their frontmatter is valid for the new parser, with minimal normalization. - Add/adjust focused tests for parser semantics and the workspace panel regression: `workflow_state: intake` plus `attention_required: null` derives `Clarify`, not `Edit`. Invariants: - Do not redesign Ticket lifecycle, workflow states, panel action model, or Ticket schema beyond parser correctness. - Keep migration diff limited to necessary `.yoi/tickets` frontmatter normalization; avoid unrelated Ticket body/thread rewrites. - Preserve generated/runtime/local/lock/secret-like `.yoi` boundaries; do not edit `.yoi/memory` or `.yoi/**/_logs/**`. - Child worktree must not edit main-workspace Ticket/workflow/docs records directly outside its delegated branch. Non-goals: - No external tracker integration. - No broad lifecycle/action-required redesign. - No compatibility layer that preserves invalid legacy raw-string semantics against YAML behavior. Escalate if: - Existing project Ticket records cannot be normalized without semantic ambiguity. - YAML parsing requires a dependency or package change that fails licensing/packaging validation. - Workspace panel regression fix requires changing action derivation semantics beyond correct typed metadata. Validation: - Focused `cargo test` for `crates/ticket` parser/doctor tests touched by the change. - Focused workspace panel test covering the `attention_required: null` regression. - `cargo fmt --check`. - `git diff --check`. - `target/debug/yoi ticket doctor` or equivalent built binary doctor. - `nix build .#yoi` because source/dependency/package behavior may change. Current code map: - `crates/ticket` local backend/item parser/frontmatter rendering/tests. - `crates/tui` workspace panel action derivation tests only if needed for regression coverage. - Existing `.yoi/tickets` records for minimal YAML normalization. Critical risks: - Accidentally treating quoted string values as null. - Over-normalizing Ticket records and creating noisy lifecycle/thread diffs. - Breaking Ticket doctor/list/show/panel reads on existing records. - Adding `serde_yaml` without updating Cargo/Nix package expectations. --- ## State changed Orchestrator accepted the queued Ticket for implementation after preflight recorded the strict YAML parsing and project-local migration boundary. Worktree and sibling coder/reviewer routing may proceed from this accepted in-progress state. --- ## Implementation report Coder delegated: - Pod: `coder-parse-ticket-frontmatter-as-yaml` - Worktree: `.worktree/parse-ticket-frontmatter-as-yaml` - Branch: `ticket/parse-ticket-frontmatter-as-yaml` - Scope: read access to main workspace only for startup/cwd; write access to the child worktree. - Instructions: implement strict YAML-compatible Ticket item frontmatter parsing, migrate existing project Ticket records minimally, add parser and workspace panel regression tests, run focused validation plus `cargo fmt --check`, `git diff --check`, Ticket doctor, and `nix build .#yoi`, then commit locally on the child branch. No merge, close, main workspace edits, or cleanup delegated. --- ## Implementation report Coder completed implementation: - Pod: `coder-parse-ticket-frontmatter-as-yaml` - Branch/worktree: `ticket/parse-ticket-frontmatter-as-yaml` at `.worktree/parse-ticket-frontmatter-as-yaml` - Commit: `10d7844fc84683429e24671bf01dd57885a40084` (`ticket: parse item frontmatter as YAML`) - Child worktree status: clean Implementation summary: - Replaced raw Ticket `item.md` frontmatter parsing with strict YAML parsing in `crates/ticket/src/lib.rs`. - Added typed handling for YAML nulls, sequences, booleans, quoted string values, and clear parse/type errors. - Removed tolerant raw-string fallbacks that conflict with YAML semantics. - Added focused parser tests and workspace panel regression coverage for `workflow_state: intake` plus `attention_required: null` deriving `Clarify`, not `Edit`. - Updated `crates/ticket/Cargo.toml`, `Cargo.lock`, and `package.nix` for `serde_yaml` / Nix cargo hash. - Migrated 48 existing `.yoi/tickets/**/item.md` files by quoting YAML-unsafe title values with colons; no bodies, threads, resolutions, or non-frontmatter content were rewritten. Reported validation: - `cargo test -p ticket --lib` — passed - `cargo test -p tui workspace_panel --lib` — passed - `cargo fmt --check` — passed - `git diff --check` — passed - `target/debug/yoi ticket doctor` — passed - `nix build .#yoi` — passed Next action: - Delegate independent read-only reviewer inspection of commit `10d7844` against the Ticket intent, strict-YAML preflight boundary, migration minimality, and validation evidence before preparing a merge-ready dossier. --- ## Implementation report Reviewer delegated: - Pod: `reviewer-parse-ticket-frontmatter-as-yaml` - Review target: commit `10d7844` on branch `ticket/parse-ticket-frontmatter-as-yaml` - Scope: read-only child worktree plus git metadata needed to inspect the branch. - Instructions: inspect parser semantics, clear failure behavior, minimal Ticket record migration, workspace panel regression coverage, dependency/package changes, and validation evidence; return `approve` or `request_changes` with blocker/non-blocker separation. No file edits, Ticket writes, merge, close, or cleanup delegated. --- ## Review: request changes Branch-local reviewer verdict: request changes. Blocker: - The parser now correctly treats schema string fields as YAML strings, but the Ticket frontmatter writer can still emit numeric-looking or otherwise ambiguous string values as plain YAML scalars. Examples such as `title: 123`, `labels: [123]`, `risk_flags: [1]`, or `assignee: 42` would be emitted as non-string YAML scalars and then rejected by the strict parser on the next read. The backend must not create/update Ticket records that its own parser rejects. Requested fix: - Make string serialization conservative, preferably always quote schema string values, or prove round-trip string-ness under `serde_yaml` before emitting plain scalars. - Add regression tests for numeric-looking strings at least for `title`, `labels`, and `risk_flags`; optional string fields such as `assignee`/`attention_required` should also be covered if they share the helper. Positive findings: - Strict YAML parsing direction is correct. - Null/list/bool parsing and clear failure behavior are covered. - Workspace panel regression coverage is present. - Migration appears limited to necessary `title:` frontmatter normalization. - Dependency/package changes looked coherent and coder-reported validation was appropriate. Validation expected after fix: - `cargo test -p ticket --lib` - `cargo test -p tui workspace_panel --lib` - `target/debug/yoi ticket doctor` or equivalent - `nix build .#yoi` if dependency/package outputs remain changed. --- ## Implementation report Coder completed reviewer-blocker fix: - Pod: `coder-parse-ticket-frontmatter-as-yaml` - Branch/worktree: `ticket/parse-ticket-frontmatter-as-yaml` at `.worktree/parse-ticket-frontmatter-as-yaml` - New commit: `dbdccc5 ticket: quote frontmatter strings conservatively` - Branch commits now: `10d7844` + `dbdccc5` - Child worktree status: clean Fix summary: - `format_yaml_string_scalar` now emits schema string values as single-quoted YAML scalars conservatively. - Applies to scalar string fields such as `title`, `assignee`, `attention_required`, list items in `labels`/`risk_flags`, and string updates through `set_frontmatter_fields`. - Added regression coverage for ambiguous/numeric-looking user strings: `title: "123"`, `labels: ["123", "01"]`, `risk_flags: ["1", "42"]`, `assignee: "42"`, `attention_required: "0"`, and `action_required: "true"`. - No extra Ticket migration rewrite was needed for the fix. Reported validation after fix: - `cargo test -p ticket --lib` — passed - `cargo test -p tui workspace_panel --lib` — passed - `cargo fmt --check` — passed - `git diff --check` — passed - `target/debug/yoi ticket doctor` — passed - `nix build .#yoi` — passed Next action: - Send the updated branch back to the reviewer for focused re-review of the prior blocker and final merge-ready verdict. --- ## Implementation report Merge-ready dossier for `orchestrator-merge-completion` Ticket: - Id: `20260607-223233-parse-ticket-frontmatter-as-yaml` - Slug: `parse-ticket-frontmatter-as-yaml` - Workflow state: `inprogress` Branch/worktree: - Branch: `ticket/parse-ticket-frontmatter-as-yaml` - Worktree: `.worktree/parse-ticket-frontmatter-as-yaml` - Child worktree status: clean (`## ticket/parse-ticket-frontmatter-as-yaml`) Commits: - `10d7844 ticket: parse item frontmatter as YAML` - `dbdccc5 ticket: quote frontmatter strings conservatively` - Diff vs `develop`: 53 files changed; source/package changes in `crates/ticket`, `crates/tui/src/workspace_panel.rs`, `Cargo.lock`, `package.nix`; 48 `.yoi/tickets/**/item.md` records minimally normalized. Intent/invariant check: - Intent satisfied: Ticket `item.md` frontmatter now parses through strict YAML-compatible typed metadata rather than raw `key: value` strings. - Human/preflight boundary followed: old tolerant raw-string semantics that conflict with YAML were not preserved. - YAML null/list/bool semantics are handled; invalid/wrong-typed frontmatter fails clearly. - Writer/parser round-trip invariant restored by conservative quoting of schema string values. - Scope stayed within parser/emitter correctness, minimal project Ticket record normalization, package dependency updates, and workspace panel regression coverage; Ticket lifecycle/state/action model was not redesigned. Implementation summary: - Replaced raw frontmatter parsing in `crates/ticket/src/lib.rs` with `serde_yaml::Value`-based strict parsing and typed helpers. - Added validation/error paths for wrong YAML field types. - Added tests for null values, quoted `"null"` as string where valid, list fields, bool fields, invalid types, and conservative string emission. - Added workspace panel regression coverage so `workflow_state: intake` plus `attention_required: null` derives `Clarify` rather than `Edit`. - Added `serde_yaml` to `crates/ticket/Cargo.toml`, updated `Cargo.lock`, and updated `package.nix` cargo hash. - Normalized existing Ticket item frontmatter by quoting YAML-unsafe `title:` values containing colons; no body/thread/resolution rewrite was introduced. Coder evidence: - Pod: `coder-parse-ticket-frontmatter-as-yaml` - Initial implementation commit: `10d7844` - Reviewer-fix commit: `dbdccc5` - Coder-reported final status: child worktree clean. - Coder-reported validation after fix: - `cargo test -p ticket --lib` — passed - `cargo test -p tui workspace_panel --lib` — passed - `cargo fmt --check` — passed - `git diff --check` — passed - `target/debug/yoi ticket doctor` — passed - `nix build .#yoi` — passed Reviewer evidence: - Pod: `reviewer-parse-ticket-frontmatter-as-yaml` - First verdict: request_changes due writer emitting ambiguous numeric-looking schema strings as plain YAML scalars. - Blocker resolution: reviewer approved after focused re-review of commit `dbdccc5`. - Reviewer inspected branch/worktree state, prior-to-fix delta, focused `crates/ticket/src/lib.rs` diff, migration scope, packaging/dependency diff, `git diff --check`, and `target/debug/yoi ticket doctor`. - Final branch-local verdict: approve. Blockers / findings: - Resolved blocker: strict parser could reject records written by the backend if schema strings were emitted as ambiguous plain YAML scalars. - Fix: schema string values are conservatively single-quoted, including list entries and update paths; regression tests cover numeric/ambiguous strings. - No remaining reviewer blockers or non-blocker required changes. Validation performed by orchestrator: - Confirmed child branch HEAD, clean status, commit list, and diff stat/name-status against `develop`. - Ran typed `TicketDoctor`: 0 errors; existing repository-wide warnings remain unrelated/truncated. Residual risks: - `serde_yaml` dependency/package change is larger than parser-only code but was validated by coder-reported `nix build .#yoi` and reviewer packaging inspection. - Ticket migration touches many item files, but the diff is intentionally limited to frontmatter title quoting needed for valid YAML parsing. - Broader historical Ticket warnings remain but are unrelated to this change. Current main workspace dirty state: - Main branch has local Ticket record modifications for this Ticket's routing/review/dossier events. - No source-code changes are present in the main workspace outside child worktrees. Pods / cleanup state: - Coder Pod is idle/reachable. - Reviewer Pod is idle/reachable. - Worktree and branch are retained for merge-completion. - No merge, final main-branch approval, close, or cleanup has been performed. Parent/human decision needed: - Authorize merge-completion if desired. Without explicit merge authority, stop here with this dossier. - Merge-completion should independently verify branch/worktree/commit identity, main workspace safety, and validation requirements before merge/close/cleanup. --- ## Review: approve Final merge-completion review: approved after authorized merge of `ticket/parse-ticket-frontmatter-as-yaml` with `--no-ff`, verification of the merge-ready dossier and branch identity, and successful post-merge validation.
