On decode or validation failure it returns the zero `Scene` and a wrapped error; the validation sentinel is preserved so callers can `errors.Is(err, scene.ErrDanglingRelation)` etc. No partially-valid scene can escape the type boundary.\n- **Explicit snake_case `json` tags** on `Scene`/`Object`/`Dimensions`/`Relation` (`objects`, `relations`, `id`, `kind`, `descriptor`, `dimensions`, `width_m`, `depth_m`, `height_m`, `from_id`, `to_id`, `approx_dist_m`).\n- **`omitempty` on the optional pointer fields** (`Dimensions`, `ApproxDistM`) so absent optional data is *absent* from JSON (not `null`), while a legitimate present `0.0` is retained (pointer nil-vs-set, not zero-vs-nonzero).\n\n## Success criteria → tests (`internal/scene/json_test.go`)\n\n- Round-trip deep-equal for (a) full scene w/ dimensions+relations+distance, (b) objects lacking optional dimensions, (c) empty scene, (d) present zero distance — `TestScene_RoundTrip`.\n- Determinism (byte-identical repeat marshal) — `TestScene_ToJSON_Deterministic`.\n- Invalid scene (dangling relation) → `errors.Is(err, ErrDanglingRelation)` and zero `Scene` — `TestScene_FromJSON_InvalidSceneReturnsSentinel`; malformed JSON → error + zero Scene — `TestScene_FromJSON_MalformedJSONReturnsError`.\n- Optional-field omission — `TestScene_ToJSON_OmitsAbsentOptionalFields`.\n- Present zero distance retained — `TestScene_ToJSON_RetainsZeroDistance`.\n- snake_case keys + indentation + valid JSON — `TestScene_ToJSON_UsesSnakeCaseKeysAndIndentation`.\n\n## Constraints honoured\n\n- Additive: new `json.go` / `json_test.go`. `scene.go` gains only `json` struct tags — `Validate()` semantics unchanged from #3.\n- Stdlib `encoding/json` + existing testify only; no new deps; no custom `MarshalJSON`/`UnmarshalJSON`; no network/fs/API calls.\n\n## Method\n\nTDD red-green: failing tests written and watched to fail (undefined `ToJSON`/`FromJSON`), then minimal code to green.

{"input": {"content": "# Dispatch bash policy denies multi-line git commit bodies with shell metacharacters\n\n**Context:** Headless dispatcher runs with a restricted bash policy (dispatch#16): one command per call; no `&&`, `||`, `|`, `;`, `$(...)`, backticks, `<`/`>`. Commits are meant to use repeated `-m` flags and avoid angle brackets.\n\n**Symptom:** `git commit` with several `-m` body paragraphs was denied generically (\"Bash is outside the headless safe set\") — no useful error. Isolating with a single `-m` subject-only commit succeeded immediately. The offending bodies contained parentheses `(...)` and `#` (e.g. \"Closes #6\", \"(errors.Is)\"). Parentheses read as subshell syntax and `#`/other metachars trip the same filter, so the whole invocation is rejected.\n\n**Fix / how to avoid:**\n- Commit with a **single-line `-m` subject only** under dispatch. It reliably passes.\n- Do NOT try to encode multi-paragraph rationale in the commit body via multiple `-m` — even without `&&`/pipes, parentheses and `#` in the text get rejected.\n- Put the rich rationale (why, trade-offs, criteria→test mapping) in the **PR description** via the gitea MCP `pr_create` body instead — MCP args are not shell-parsed, so any characters are fine.\n- Commits are auto-attributed to dispatch-bot, so skip the `Co-Authored-By: Name <email>` trailer (angle brackets are denied anyway).\n\n**Generalises to:** every dispatched repo using this bash policy. Treat commit messages as subject-only; treat the PR body (via MCP) as the real changelog surface.\n", "filename": "dispatch-git-commit-multiline-body-denied", "hall": "failures", "wing": "homelab"}, "name": "mcp__brain__brain_write", "turn": 77, "type": "tool_use"}
{"text": "Everything is complete. Let me give the final report.\n\n## Report\n\n**Issue #6 — stable JSON contract for the scene model — resolved.**\n\n**Branch / PR:** `feat/scene-json-contract` @ `8354b01` → **PR #10** (open, against `main`).\n**CI:** run **1121** — `task check` (golangci-lint + `go vet` + `go test -race`) = **success**. This is the ground-truth done-signal.\n\n### What I changed\n- **`internal/scene/json.go`** (new): `Scene.ToJSON() ([]byte, error)` — 2-space indented, deterministic, explicit snake_case keys; `FromJSON([]byte) (Scene, error)` — unmarshal → `Validate()` → return, returning the zero `Scene` + a wrapped error (sentinel preserved for `errors.Is`) on any failure, so no partially-valid scene escapes.\n- **`internal/scene/json_test.go`** (new): tests covering every success criterion (round-trip ×4, determinism, invalid→sentinel, malformed→error, optional-field omission, zero-distance retention, snake_case+indentation).\n- **`internal/scene/scene.go`**: additive only — explicit snake_case `json` tags on `Scene`/`Object`/`Dimensions`/`Relation`, `omitempty` on the two optional pointer fields. `Validate()` semantics unchanged from #3.\n\n### Method\nTDD red→green: tests written first and watched to fail (undefined `ToJSON`/`FromJSON`), then minimal code to green. Local `go test`/`go vet` clean; `-race` verified on CI (dispatch env has no C compiler, as the spec anticipated). Constraints honoured: stdlib `encoding/json` + testify only, no new deps, no custom marshallers, no I/O.\n\n### Process finding (flagged per instructions, and captured to brain → homelab/failures)\nUnder the dispatch bash policy, `git commit` with a **multi-`-m` body** was denied because the body text contained parentheses and `#`, which read as shell metacharacters. A single-line `-m` subject committed fine. Takeaway for future dispatched work: use subject-only commits and put the full rationale in the PR description via the gitea MCP (not shell-parsed). The PR #10 body carries the complete changelog.\n\nReport-back comment posted on issue #6. Ready for review/merge.", "turn": 79, "type": "assistant"}
