+# Gitea Access (tea CLI)
+
+**Never access the Gitea API directly** — use the `tea` CLI with all required flags to bypass interactive mode.
+
+Always pass `--login schweitz --repo jpmschweitzer/settled-reach --output simple` to avoid TTY prompts.
+
+```bash
+# List open PRs
+tea pr list --login schweitz --repo jpmschweitzer/settled-reach --state open --output simple

+# View a PR with comments

+
+# List issues
+tea issue list --login schweitz --repo jpmschweitzer/settled-reach --state open --output simple
+```
+
+## Key rules
+
+- **All flags must be explicit** — omitting `--login` or `--repo` triggers interactive prompts that crash in Claude Code (no TTY)
+- **Use `--output simple`** for machine-readable output (no table borders)
+- **For comments, use `tooling/tea-comment <number> "body"`** — handles temp files and cleanup automatically. Works with multi-line strings.
+- **`tea pr reject` does not work on your own PRs** — use `tea comment` instead
+- **Never delete protected branches:** `main`, `maintenance`, `server`, `client`, `copy`, `audio`, `visual`, `ci` are protected on Gitea. Do not use `tea pr clean`, `git push --delete`, or `git branch -D` on these branches.
+
+## Pull requests
+
+**Use `tea` (Gitea CLI), not `gh` (GitHub CLI).** The remote is Gitea at `git.schweitz.internal`.
+
+Always provide all required flags to ensure non-interactive execution:
+```bash
+tea pr create \

+  --login schweitz \
+  --title "feat(scope): short description" \

+# Team Patterns
+
+## Model selection
+
+Default model is Opus 4.6 (200K context). For heavy sessions (workshops,
+sprint planning, large reviews), switch to extended context on-demand:
+
+- `/model sonnet[1m]` — Sonnet 4.6 with 1M context window
+- `/model opus[1m]` — Opus 4.6 with 1M context window
+- Cost: 2x input + 1.5x output for tokens beyond 200K (Tier 4 required)
+
+## Large content pushes
+
+When producing many files (wiki pages, content batches, bulk docs):
+1. **Lore librarian** agent (read-only): ingests all source material, answers focused context queries from writers, tracks cross-file consistency
+2. **Multiple writer** agents (parallel, by domain): each gets a task slice, writes directly to disk using the Write tool — one file at a time, write often, no text accumulation
+3. **Reviewer** agents (blocked until writing done): check voice consistency, attribute uniformity, style
+
+Key: writers use Write tool directly (no transcription bottleneck), librarian catches contradictions early, split work by domain not volume.
+
+## Team monitoring (stuck agent detection)
+
+When leading a team (sprint, workshop, or any multi-agent session):
+
+**Agent heartbeat rule** — include in every agent spawn prompt:
+> If you have been working on a single task for more than 15 minutes
+> without making progress, message the team lead with what is blocking
+> you. Do not keep retrying the same approach silently.
+
+**Team lead proactive checks:**
+- If an agent has not sent a message in ~20 minutes, ping them for a status update.
+- **Bottleneck detection:** if other agents are idle and waiting on one agent's output, that agent's silence is a red flag — check on them immediately, do not wait for the next natural message.
+- When checking on a stuck agent, offer to reassign the task or pull in another agent to help.

+
+    3. READ BEFORE WRITE: Before modifying ANY file, Read it first.
+       Before creating a new file, Glob for similar files to learn
+       the existing patterns (naming, structure, imports). Follow
+       the conventions you find — do not invent new ones.
+
+    4. VERIFY AFTER WRITE: After implementing a change, grep for
+       all references to functions/properties/classes you modified
+       or removed. If you renamed, moved, or deleted something,
+       update EVERY call site. Missing a call site breaks tests
+       and blocks the team.
+
+    5. NO PARTIAL WORK: Do not mark a task completed unless ALL
+       parts of the ticket are implemented. If the ticket says
+       'deliver A, B, and C', all three must exist and work. If
+       you cannot complete part of a task, message the team lead
+       explaining what is blocked and what remains — do NOT mark
+       it completed.
+
+    6. MESSAGE WHEN BLOCKED: If you hit a problem you cannot solve
+       in 3 attempts, stop and message the team lead immediately.
+       Do not silently skip work or leave stubs. Do not move to
+       the next task while the current one is incomplete.
+
+    7. BACKWARD COMPATIBILITY: When extracting, moving, or
+       refactoring code, ensure all existing consumers still work.
+       Add proxy methods/properties if needed. Grep for the old
+       name to find every call site.
+
+    WORKFLOW:
 
     1. Read the sprint briefing: docs/sprints/sprint-{N}/{team}.md
     2. Read the decision files referenced in the briefing.
     3. Check TaskList for available work.
     4. Claim an unblocked task (TaskUpdate with owner: your name),
        mark it in_progress, and implement it.
-    5. When done, mark the task completed and check TaskList for
-       the next available task.
+    5. Before marking done, verify:
+       - All deliverables from the ticket exist (not just some)
+       - No broken references (grep for changed names/signatures)
+       - New files follow existing naming and directory conventions
+       - Modified files still parse (no syntax errors)
+    6. Mark the task completed and check TaskList for the next

+   - Severity (critical / warning / suggestion)

+
+4. After all review-fix tasks are complete, re-run `/git-commit` then

+5. Repeat this loop until review returns APPROVED.

+  model: "haiku",
+  prompt: "Run /sprint-status. Read the skill at

+```
+
+Present the subagent's output to the user verbatim. Do NOT run the
+workflow yourself.
+
+---
+
+The remainder of this file is the subagent's reference for executing
+the workflow.
+
+## Step 1 — Gather data
+
+Run these two commands in parallel:
+
+```bash
+db/connectors/sprint sweep
+```
+
+```bash
+tea pr list --login schweitz --repo jpmschweitzer/settled-reach --state open --output simple
+```
+
+The `sweep` command returns JSON with:
+- `sprint` — id, name, goal
+- `progress` — total, done, pct
+- `by_status` — tickets grouped into done, review, in_progress, blocked, backlog
+- `by_team` — per-team counts
+- `issues` — bookkeeping problems with suggested fix commands
+
+The `tea pr list` returns open PRs as `#N title` lines.
+
+## Step 2 — Cross-reference PRs with tickets
+
+Parse PR head branches from the `tea pr list` output. Known team branches:
+`server`, `client`, `copy`, `audio`, `visual`, `ci`.
+
+Detect additional issues:
+
+- **done_team_open_pr**: A team's tickets are all done but an open PR
+  still exists for that team branch.
+- **orphan_pr**: An open PR exists on a branch that has no tickets in
+  the active sprint.
+
+Add these to the issues list from step 1.
+
+## Step 3 — Format output
+
+Read `references/output-template.md` for the exact format spec.
+
+Render the report using data from steps 1-2. Key rules:
+- Sections ordered: Completed, In Review, In Progress, Blocked, Backlog
+- Sort tickets within sections by team then ticket ID
+- Empty sections: show header with "(0)" and "(none)" — no empty table
+- Bookkeeping Issues: two-column table (Issue, Fix)
+- Open Work by Team: summary table at the bottom
+- Issue type labels: `stale_backlog` → "Stale backlog",
+  `unassigned_in_progress` → "Unassigned in_progress",
+  `assigned_but_done` → "Assigned but done",
+  `done_team_open_pr` → "Done team with open PR",
+  `orphan_pr` → "Orphan PR"
+
+## Step 4 — Suggest actions
+
+After the formatted report, if there are bookkeeping issues, add a
+"Suggested fixes" section with the fix command for each issue. Group
+by issue type for readability.

+
+### Changed

+- Shared run_dialogue_pipeline() helper eliminates ~60 lines of duplication between Talk and DialogueResponse systems
+- Dialogue and monologue line IDs migrated from location-scoped (the-terminal_d_039) to NPC-scoped (kael-davan_d_001) namespace — each NPC has an independent sequence per D-035 (#542)

+- Schedule ambiguity: emit_observation_events now has explicit .before(advance_tick) constraint
+- process_dialogue_response updates ActiveDialogue tick and InteractionMemory on follow-up
+- DialogueResponse range check added (CLOSE_RANGE, matching Talk/Confront pattern)
+- Weighted selection fallback replaced with unreachable!() — dead code removed

 ### Worktree boundaries
 
-This project uses **git worktrees** in a shared parent directory (`settled-reach/`). Each team branch (`server`, `client`, `copy`, `audio`, `visual`, `ci`) is checked out in its own worktree under that parent. The parent directory also contains shared resources like the ticketing database.
+This project uses **git worktrees** in a shared parent directory (`settled-reach/`). Each team branch (`server`, `client`, `copy`, `audio`, `visual`, `ci`) has its own worktree. The worktree root IS the git root.
 
-Each worktree contains the full repository: `server/` (Rust backend), `client/` (Godot client), `docs/`, `decisions/`, etc. The worktree root IS the git root — use `git rev-parse --show-toplevel` if in doubt.
-
-Unless there is a direct instruction or a functional need (e.g. accessing the shared database in the parent directory), **all work must remain within the scope of the git root Claude is running in.**
-
-- All file paths are relative to the worktree/git root (e.g. `server/src/bridge/types.rs`, `client/scripts/rendering/fog.gd`).
-- Do not navigate to or access sibling worktrees in the parent directory (`../client/`, `../copy/`, etc.) unless explicitly instructed.
-- Do not navigate above the git root unless explicitly instructed.

+- **Exception — stale git lock files:** Worktree index locks live in the shared `.git` directory (e.g. `main/.git/worktrees/copy/index.lock`). If a `git` command fails with `index.lock: File exists`, you may remove the lock file for **your own worktree only**. Never touch lock files belonging to other worktrees.

-### Ticket and database access
-**Prefer the ticket CLI over raw SQL.** The CLI handles column names, joins, and output formatting correctly:
-```bash
-db/connectors/ticket list --sprint 2 --team server
-db/connectors/ticket show 78
-db/connectors/ticket sprint --active
-```
+### CLI tools
 
-### Sprint CLI
-**Use the sprint CLI for sprint-scoped operations.** It batches ticket queries and formats output for agent consumption:
-```bash
-db/connectors/sprint status                    # Current sprint progress
-db/connectors/sprint status --team server      # Team-scoped view
-db/connectors/sprint start-work --team client  # Full context dump for starting work
-db/connectors/sprint prepare                   # Prepare next sprint (candidates + gaps)
-db/connectors/sprint start                     # Activate a planned sprint
-db/connectors/sprint stop                      # Complete an active sprint
-```
-Team is auto-detected from the current git branch (if not `main`). Sprint is auto-detected from DB state.
+**Prefer CLI wrappers over raw SQL.** Never use the `sqlite3` CLI — it crashes in Claude Code (std::bad_alloc). Use the wrapper scripts instead.
 
-Only fall back to raw SQL for queries the CLI doesn't support. **Never use the `sqlite3` CLI** — it crashes in Claude Code due to a known std::bad_alloc bug. Use the wrapper scripts instead:
-```bash
-db/connectors/sqlite-query "SELECT * FROM tickets WHERE status='in_progress'"
-db/connectors/sqlite-exec "UPDATE tickets SET status='done' WHERE id=1"
-```
-
-### Qdrant / document search
-```bash
-db/connectors/qdrant-search "asymmetric information design"
-db/connectors/qdrant-index docs/briefings/tyre.md
-db/connectors/qdrant-health
-db/connectors/qdrant-count
-```
-
-### Gitea access (tea CLI)
-**Never access the Gitea API directly** — use the `tea` CLI with all required flags to bypass interactive mode.
-
-Always pass `--login schweitz --repo jpmschweitzer/settled-reach --output simple` to avoid TTY prompts.
-
-```bash
-# List open PRs
-tea pr list --login schweitz --repo jpmschweitzer/settled-reach --state open --output simple
-
-# View a PR with comments
-tea pr --login schweitz --repo jpmschweitzer/settled-reach --comments -o simple <PR_NUMBER>
-
-# Post a comment on a PR (or issue)
-tea comment --login schweitz --repo jpmschweitzer/settled-reach <NUMBER> "comment body"
-
-# Approve a PR
-tea pr approve --login schweitz --repo jpmschweitzer/settled-reach <PR_NUMBER>
-
-# List issues
-tea issue list --login schweitz --repo jpmschweitzer/settled-reach --state open --output simple
-```
-
-Key rules:
-- **All flags must be explicit** — omitting `--login` or `--repo` triggers interactive prompts that crash in Claude Code (no TTY)
-- **Use `--output simple`** for machine-readable output (no table borders)
-- **`tea comment` hangs with inline heredocs and multi-line strings.** Always write the comment body to a temp file first, then pass it via `$(cat)`:
-  ```bash
-  # Step 1: Write content to .tmp/ (gitignored) using the Write tool
-  # Step 2: Post via cat
-  tea comment --login schweitz --repo jpmschweitzer/settled-reach <NUMBER> "$(cat .tmp/review-branch.md)"
-  ```
-- **`tea pr reject` does not work on your own PRs** — use `tea comment` instead
-- **Never delete protected branches:** `main`, `maintenance`, `server`, `client`, `copy`, `audio`, `visual`, `ci` are protected on Gitea. Do not use `tea pr clean`, `git push --delete`, or `git branch -D` on these branches.

 - Decision IDs: `D-NNN` (confirmed), `Q-NNN` (open questions), `R-NNN` (rejected)
+- **Claim IDs before writing:** `db/connectors/decision claim D <domain> "title"` — prevents ID collisions across worktrees
 - Diagrams: `.d2` source + `.png` renders in `docs/diagrams/{category}/`. Create or update diagrams via `/d2-diagram` when D-records are added or modified.
 - Discussion rounds: numbered sequentially, archived to `docs/discussions/` when complete
 - Briefings: one per agent, updated after decision-producing rounds
 - Tickets: managed via `db/connectors/ticket` CLI or `/ticket` skill

-### Commit conventions
-Use conventional commits with project-specific scopes:
-`agents`, `skills`, `docs`, `briefings`, `discussions`, `schema`, `db`, `config`, `engine`, `simulation`, `client`, `ui`, `audio`, `assets`, `meta`
-
-### Pull requests
-**Use `tea` (Gitea CLI), not `gh` (GitHub CLI).** The remote is Gitea at `git.schweitz.internal`.
-
-Always provide all required flags to ensure non-interactive execution:
-```bash
-tea pr create \
-  --repo jpmschweitzer/settled-reach \
-  --login schweitz \
-  --title "feat(scope): short description" \
-  --description "PR body here" \
-  --base main \
-  --head branch-name
-```
-
-### Large content pushes (team pattern)
-When producing many files (wiki pages, content batches, bulk docs):
-1. **Lore librarian** agent (read-only): ingests all source material, answers focused context queries from writers, tracks cross-file consistency
-2. **Multiple writer** agents (parallel, by domain): each gets a task slice, writes directly to disk using the Write tool — one file at a time, write often, no text accumulation
-3. **Reviewer** agents (blocked until writing done): check voice consistency, attribute uniformity, style
-
-Key: writers use Write tool directly (no transcription bottleneck), librarian catches contradictions early, split work by domain not volume.
-
-### Local services
-- Gitea: `http://git.schweitz.internal` (login: `schweitz`)
-- Qdrant: `http://tower-of-joy:6333/`
-- Ollama: `http://tower-of-joy:11434/` (nomic-embed-text)

+## Sprint 17 — Time display on insert HUD (#263)
+## Tests for Constants.format_game_time(), InsertClock wiring, and GameState integration.
+##
+## Spec refs:
+##   D-031 (game time: 10 ticks = 1 game-minute, 1440 min/day, HH:MM display)
+##   D-051 (diegetic insert display)
+##
+## Implementation: client/ui/time_display.gd — draw-based Control at InsertOverlay/TimeDisplay.
+## Format function: Constants.format_game_time(time_of_day: int) -> String (extracted for
+## testability from time_display.gd:46 inline Constants.format_game_time(tod)).
+##
+## Private state access: Tests read _time_str, _phase_str, _day_str, _has_data directly
+## because time_display.gd is draw-based (no Label nodes to inspect). This is an accepted
+## test pattern for draw-based UI — the private vars ARE the rendered output contract.
+## If the rendering approach changes (e.g. to Label nodes), these tests should switch to
+## reading Label.text via public node paths instead.
