fix(workflows): agent-skills query keys must match subagent_type (follow-up to #2555) (#2616)

* fix(workflows): agent-skills query keys must match subagent_type

Eight workflow files called `gsd-sdk query agent-skills <KEY>` with
a key that did not match any `subagent_type` Task() spawns in the
same workflow (or any existing `agents/<KEY>.md`):

- research-phase.md:45 — gsd-researcher    → gsd-phase-researcher
- plan-phase.md:36     — gsd-researcher    → gsd-phase-researcher
- plan-phase.md:38     — gsd-checker       → gsd-plan-checker
- quick.md:145         — gsd-checker       → gsd-plan-checker
- verify-work.md:36    — gsd-checker       → gsd-plan-checker
- new-milestone.md:207 — gsd-synthesizer   → gsd-research-synthesizer
- new-project.md:63    — gsd-synthesizer   → gsd-research-synthesizer
- ui-review.md:21      — gsd-ui-reviewer   → gsd-ui-auditor
- discuss-phase.md:114 — gsd-advisor       → gsd-advisor-researcher

Effect before this fix: users configuring `agent_skills.<correct-type>`
in .planning/config.json got no injection on these paths because the
workflow asked the SDK for a different (non-existent) key. The SDK
correctly returned "" for the unknown key, which then interpolated as
an empty string into the Task() prompt. Silent no-op.

The discuss-phase advisor case is a subtle variant — the spawn site
uses `subagent_type="general-purpose"` and loads the agent role via
`Read(~/.claude/agents/gsd-advisor-researcher.md)`. The injection key
must follow the agent identity (gsd-advisor-researcher), not the
technical spawn type.

This is a follow-up to #2555 — the SDK-side fix in that PR (#2587)
only becomes fully effective once the call sites use the right keys.

Adds `sdk/src/workflow-agent-skills-consistency.test.ts` as a
contract test: every `agent-skills <slug>` invocation in
`get-shit-done/workflows/**/*.md` must reference an existing
`agents/<slug>.md`. Fails loudly on future key typos.

Closes #2615

* test: harden workflow agent-skills regex per review feedback

Review (#2616): CodeRabbit flagged the `agent-skills <slug>` pattern
as too permissive (can match prose mentions of the string) and the
per-line scan as brittle (misses commands wrapped across lines).

- Require full `gsd-sdk query agent-skills` prefix before capture
  + `\b` around the pattern so prose references no longer match.
- Scan each file's full content (not line-by-line) so `\s+` can span
  newlines; resolve 1-based line number from match index.
- Add JSDoc on helpers and on QUERY_KEY_PATTERN.

Verified: RED against base (`f30da83`) produces the same 9 violations
as before; GREEN on fixed tree.

+ * Effective per-agent model_overrides for the Codex / OpenCode install paths.
+ *
+ * Merges `~/.gsd/defaults.json` (global) with per-project

+ * user can tune a single agent's model in one repo without re-setting the
+ * global defaults for every other repo. Non-conflicting keys from both
+ * sources are preserved.
+ *
+ * This is the fix for #2256: both adapters previously read only the global
+ * file, so a per-project `model_overrides` (the common case the reporter
+ * described — a per-project override for `gsd-codebase-mapper` in
+ * `.planning/config.json`) was silently dropped and child agents inherited
+ * the session default.
+ *
+ * `targetDir` is the consuming runtime's install root (e.g. `~/.codex` for
+ * a global install, or `<project>/.codex` for a local install). We walk up
+ * from there looking for `.planning/` so both cases resolve the correct
+ * project root. When `targetDir` is null/undefined only the global file is
+ * consulted (matches prior behavior for code paths that have no project
+ * context).
+ *
+ * Returns a plain `{ agentName: modelId }` object, or `null` when neither
+ * source defines `model_overrides`.

+#### Progressive disclosure for workflows
+
+Workflow files are loaded verbatim into Claude's context every time the
+corresponding `/gsd:*` command is invoked. To keep that cost bounded, the
+workflow size budget enforced by `tests/workflow-size-budget.test.cjs`
+mirrors the agent budget from #2361:
+
+| Tier      | Per-file line limit |
+|-----------|--------------------|
+| `XL`      | 1700 — top-level orchestrators (`execute-phase`, `plan-phase`, `new-project`) |
+| `LARGE`   | 1500 — multi-step planners and large feature workflows |
+| `DEFAULT` | 1000 — focused single-purpose workflows (the target tier) |
+
+`workflows/discuss-phase.md` is held to a stricter <500-line ceiling per
+issue #2551. When a workflow grows beyond its tier, extract per-mode bodies
+into `workflows/<workflow>/modes/<mode>.md`, templates into
+`workflows/<workflow>/templates/`, and shared knowledge into
+`get-shit-done/references/`. The parent file becomes a thin dispatcher that
+Reads only the mode and template files needed for the current invocation.
+
+`workflows/discuss-phase/` is the canonical example of this pattern —
+parent dispatches, modes/ holds per-flag behavior (`power.md`, `all.md`,
+`auto.md`, `chain.md`, `text.md`, `batch.md`, `analyze.md`, `default.md`,

+checkpoint.json schemas that are read only when the corresponding output

 2. **STATE.md file locking** — All `writeStateMd()` calls use lockfile-based mutual exclusion (`STATE.md.lock` with `O_EXCL` atomic creation). This prevents the read-modify-write race condition where two agents read STATE.md, modify different fields, and the last writer overwrites the other's changes. Includes stale lock detection (10s timeout) and spin-wait with jitter.

 ## Overview
 
-`gsd-tools.cjs` is a Node.js CLI utility that replaces repetitive inline bash patterns across GSD's ~50 command, workflow, and agent files. It centralizes: config parsing, model resolution, phase lookup, git commits, summary verification, state management, and template operations.
+`gsd-tools.cjs` centralizes config parsing, model resolution, phase lookup, git commits, summary verification, state management, and template operations across GSD commands, workflows, and agents.
 
-**Preferred for new orchestration:** Many of the same operations are available as `gsd-sdk query <command>` (see `sdk/src/query/index.ts` and `docs/QUERY-HANDLERS.md`). Use that in workflows and examples where the handler exists; keep `node … gsd-tools.cjs` for commands not yet in the registry (for example graphify) or when you need CJS-only flags.

+
+## SDK and programmatic access
+
+Use this when authoring workflows, not when you only need the command list below.
+
+**1. CLI — `gsd-sdk query <argv…>`**
+
+- Resolves argv with the same **longest-prefix** rules as the typed registry (`resolveQueryArgv` in `sdk/src/query/registry.ts`). Unregistered commands **fail fast** — use `node …/gsd-tools.cjs` only for handlers not in the registry.
+- Full matrix (CJS command → registry key, CLI-only tools, aliases, golden tiers): [sdk/src/query/QUERY-HANDLERS.md](../sdk/src/query/QUERY-HANDLERS.md).
+
+**2. TypeScript — `@gsd-build/sdk` (`GSDTools`, `createRegistry`)**
+
+- `GSDTools` (used by `PhaseRunner`, `InitRunner`, and `GSD.createTools()`) always shells out to `gsd-tools.cjs` via `execFile` — there is no in-process registry path on this class. For typed, in-process dispatch use `createRegistry()` from `sdk/src/query/index.ts`, or invoke `gsd-sdk query` (see [QUERY-HANDLERS.md](../sdk/src/query/QUERY-HANDLERS.md)).
+- Conventions: mutation event wiring, `GSDError` vs `{ data: { error } }`, locks, and stubs — [QUERY-HANDLERS.md](../sdk/src/query/QUERY-HANDLERS.md).
+
+**CJS → SDK examples (same project directory):**
+
+
+| Legacy CJS                               | Preferred `gsd-sdk query` (examples) |
+| ---------------------------------------- | ------------------------------------ |
+| `node gsd-tools.cjs init phase-op 12`    | `gsd-sdk query init phase-op 12`     |
+| `node gsd-tools.cjs phase-plan-index 12` | `gsd-sdk query phase-plan-index 12`  |
+| `node gsd-tools.cjs state json`          | `gsd-sdk query state json`           |
+| `node gsd-tools.cjs roadmap analyze`     | `gsd-sdk query roadmap analyze`      |
+
+
+**SDK state reads:** `gsd-sdk query state json` / `state.json` and `gsd-sdk query state load` / `state.load` currently share one native handler (rebuilt STATE.md frontmatter — CJS `cmdStateJson`). The legacy CJS `state load` payload (`config`, `state_raw`, existence flags) is still **CLI-only** via `node …/gsd-tools.cjs state load` until a separate registry handler exists. Full routing and golden rules: [QUERY-HANDLERS.md](../sdk/src/query/QUERY-HANDLERS.md).
+
+**CLI-only (not in registry):** e.g. **graphify**, **from-gsd2** / **gsd2-import** — call `gsd-tools.cjs` until registered.
+
+**Mutation events (SDK):** `QUERY_MUTATION_COMMANDS` in `sdk/src/query/index.ts` lists commands that may emit structured events after a successful dispatch. Exceptions called out in QUERY-HANDLERS: `state validate` (read-only), `skill-manifest` (writes only with `--write`), `intel update` (stub).
+
+**Golden parity:** Policy and CJS↔SDK test categories are documented under **Golden parity** in [QUERY-HANDLERS.md](../sdk/src/query/QUERY-HANDLERS.md).

+## Secret Handling
+
+API keys configured via `/gsd-settings-integrations` (`brave_search`, `firecrawl`, `exa_search`) are written plaintext to `.planning/config.json` but are masked (`****<last-4>`) in every `config-set` / `config-get` output, confirmation table, and interactive prompt. See `get-shit-done/bin/lib/secrets.cjs` for the masking implementation. The `config.json` file itself is the security boundary — protect it with filesystem permissions and keep it out of git (`.planning/` is gitignored by default).

+
+Interactive configuration of power-user knobs — plan bounce, subagent timeouts, branch templates, cross-AI delegation, context window, and runtime output. Use after `/gsd-settings` once the common-case toggles are dialed in.
+
+Six sections, each a focused prompt batch:
+
+| Section | Keys |
+|---------|------|
+| Planning Tuning | `workflow.plan_bounce`, `workflow.plan_bounce_passes`, `workflow.plan_bounce_script`, `workflow.subagent_timeout`, `workflow.inline_plan_threshold` |
+| Execution Tuning | `workflow.node_repair`, `workflow.node_repair_budget`, `workflow.auto_prune_state` |
+| Discussion Tuning | `workflow.max_discuss_passes` |
+| Cross-AI Execution | `workflow.cross_ai_execution`, `workflow.cross_ai_command`, `workflow.cross_ai_timeout` |
+| Git Customization | `git.base_branch`, `git.phase_branch_template`, `git.milestone_branch_template` |
+| Runtime / Output | `response_language`, `context_window`, `search_gitignored`, `graphify.build_timeout` |
+
+Current values are pre-selected; an empty input keeps the existing value. Numeric fields reject non-numeric input and re-prompt. Null-allowed fields (`plan_bounce_script`, `cross_ai_command`, `response_language`) accept an empty input as a clear. Writes route through `gsd-sdk query config-set`, which preserves every unrelated key.
+
+```bash
+/gsd-settings-advanced              # Six-section interactive config
+```
+
+See [CONFIGURATION.md](CONFIGURATION.md) for the full schema and defaults.
+
+### `/gsd-settings-integrations`
+
+Interactive configuration of third-party integrations and cross-tool routing.
+Distinct from `/gsd-settings` (workflow toggles) — this command handles
+connectivity: API keys, reviewer CLI routing, and agent-skill injection.
+
+Covers:
+
+- **Search integrations:** `brave_search`, `firecrawl`, `exa_search` API keys,
+  and the `search_gitignored` toggle.
+- **Code-review CLI routing:** `review.models.{claude,codex,gemini,opencode}`
+  — a shell command per reviewer flavor.
+- **Agent-skill injection:** `agent_skills.<agent-type>` — skill names
+  injected into an agent's spawn frontmatter. Agent-type slugs are validated
+  against `[a-zA-Z0-9_-]+` so path separators and shell metacharacters are
+  rejected.
+
+API keys are stored plaintext in `.planning/config.json` but displayed masked
+(`****<last-4>`) in every interactive output, confirmation table, and
+`config-set` stdout/stderr line. Plaintext is never echoed, never logged,
+and never written to any file outside `config.json` by this workflow.
+

+## Integration Settings
+
+Configured interactively via [`/gsd-settings-integrations`](COMMANDS.md#gsd-settings-integrations). These are *connectivity* settings — API keys and cross-tool routing — and are intentionally kept separate from `/gsd-settings` (workflow toggles).
+
+### Search API keys
+
+API key fields accept a string value (the key itself). They can also be set to the sentinels `true`/`false`/`null` to override auto-detection from env vars / `~/.gsd/*_api_key` files (legacy behavior, see rows above).
+
+| Setting | Type | Default | Description |
+|---------|------|---------|-------------|
+| `brave_search` | string \| boolean \| null | `null` | Brave Search API key used for web research. Displayed as `****<last-4>` in all UI / `config-set` output; never echoed plaintext |
+| `firecrawl` | string \| boolean \| null | `null` | Firecrawl API key for deep-crawl scraping. Masked in display |
+| `exa_search` | string \| boolean \| null | `null` | Exa Search API key for semantic search. Masked in display |
+
+**Masking convention (`get-shit-done/bin/lib/secrets.cjs`):** keys 8+ characters render as `****<last-4>`; shorter keys render as `****`; `null`/empty renders as `(unset)`. Plaintext is written as-is to `.planning/config.json` — that file is the security boundary — but the CLI, confirmation tables, logs, and `AskUserQuestion` descriptions never display the plaintext. This applies to the `config-set` command output itself: `config-set brave_search <key>` returns a JSON payload with the value masked.
+
+### Code-review CLI routing
+
+`review.models.<cli>` maps a reviewer flavor to a shell command. The code-review workflow shells out using this command when a matching flavor is requested.
+
+| Setting | Type | Default | Description |
+|---------|------|---------|-------------|
+| `review.models.claude` | string | (session model) | Command for Claude-flavored review. Defaults to the session model when unset |
+| `review.models.codex` | string | `null` | Command for Codex review, e.g. `"codex exec --model gpt-5"` |

+| `review.models.opencode` | string | `null` | Command for OpenCode review, e.g. `"opencode run --model claude-sonnet-4"` |
+
+The `<cli>` slug is validated against `[a-zA-Z0-9_-]+`. Empty or path-containing slugs are rejected by `config-set`.
+
+### Agent-skill injection (dynamic)
+
+`agent_skills.<agent-type>` extends the `agent_skills` map documented below. Slug is validated against `[a-zA-Z0-9_-]+` — no path separators, no whitespace, no shell metacharacters. Configured interactively via `/gsd-settings-integrations`.

+## Decision Coverage Gates (`workflow.context_coverage_gate`)
+
+When `discuss-phase` writes implementation decisions into CONTEXT.md
+`<decisions>`, two gates ensure those decisions survive the trip into
+plans and shipped code (issue #2492).
+
+| Setting | Type | Default | Description |
+|---------|------|---------|-------------|
+| `workflow.context_coverage_gate` | boolean | `true` | Toggle for both decision-coverage gates. When `false`, both the plan-phase translation gate and the verify-phase validation gate skip silently. |
+
+### What the gates do
+
+**Plan-phase translation gate (BLOCKING).** Runs immediately after the
+existing requirements coverage gate, before plans are committed. For each
+trackable decision in `<decisions>`, it checks that the decision id
+(`D-NN`) or its text appears in at least one plan's `must_haves`,
+`truths`, or body. A miss surfaces the missing decision by id and refuses
+to mark the phase planned.
+
+**Verify-phase validation gate (NON-BLOCKING).** Runs alongside the other
+verify steps. Searches every shipped artifact (PLAN.md, SUMMARY.md, files
+modified, recent commit subjects) for each trackable decision. Misses are
+written to VERIFICATION.md as a warning section but do **not** flip the
+overall verification status. The asymmetry is deliberate — by verify time
+the work is done, and a fuzzy substring miss should not fail an otherwise
+green phase.
+
+### How to write decisions the gates accept
+
+The discuss-phase template already produces `D-NN`-numbered decisions.
+The gate is happiest when:
+
+1. Every plan that implements a decision **cites the id** somewhere —
+   `must_haves.truths: ["D-12: bit offsets exposed"]` or a `D-12:` mention
+   in the plan body. Strict id match is the cheapest, deterministic path.
+2. Soft phrase matching is a fallback for paraphrases — if a 6+-word slice
+   of the decision text appears verbatim in a plan/summary, it counts.
+
+### Opt-outs
+
+A decision is **not** subject to the gates when any of the following
+apply:
+
+- It lives under the `### Claude's Discretion` heading inside `<decisions>`.
+- It is tagged `[informational]`, `[folded]`, or `[deferred]` in its
+  bullet (e.g., `- **D-08 [informational]:** Naming style for internal
+  helpers`).
+
+Use these escape hatches when a decision genuinely doesn't need plan
+coverage — implementation discretion, future ideas captured for the
+record, or items already deferred to a later phase.

+`model_overrides` can be set in either `.planning/config.json` (per-project)

+non-conflicting global entries are preserved, so you can tune a single

+### Runtime-Aware Profiles (#2517)
+
+When `runtime` is set, profile tiers (`opus`/`sonnet`/`haiku`) resolve to runtime-native model IDs instead of Claude aliases. This lets a single shared `.planning/config.json` work cleanly across Claude and Codex.
+
+**Built-in tier maps:**
+
+| Runtime | `opus` | `sonnet` | `haiku` | reasoning_effort |
+|---------|--------|----------|---------|------------------|
+| `claude` | `claude-opus-4-6` | `claude-sonnet-4-6` | `claude-haiku-4-5` | (not used) |
+| `codex` | `gpt-5.4` | `gpt-5.3-codex` | `gpt-5.4-mini` | `xhigh` / `medium` / `medium` |
+
+**Codex example** — one config, tiered models, no large `model_overrides` block:
+
+```json
+{
+  "runtime": "codex",
+  "model_profile": "balanced"
+}
+```
+
+This resolves `gsd-planner` → `gpt-5.4` (xhigh), `gsd-executor` → `gpt-5.3-codex` (medium), `gsd-codebase-mapper` → `gpt-5.4-mini` (medium). The Codex installer embeds `model = "..."` and `model_reasoning_effort = "..."` in each generated agent TOML.
+
+**Claude example** — explicit opt-in resolves to full Claude IDs (no `resolve_model_ids: true` needed):
+
+```json
+{
+  "runtime": "claude",
+  "model_profile": "quality"
+}
+```
+
+**Per-runtime overrides** — replace one or more tier defaults:
+
+```json
+{
+  "runtime": "codex",
+  "model_profile": "quality",
+  "model_profile_overrides": {
+    "codex": {
+      "opus": "gpt-5-pro",
+      "haiku": { "model": "gpt-5-nano", "reasoning_effort": "low" }
+    }
+  }
+}
+```
+
+**Precedence (highest to lowest):**
+
+1. `model_overrides[<agent>]` — explicit per-agent ID always wins.
+2. **Runtime-aware tier resolution** (this section) — when `runtime` is set and profile is not `inherit`.
+3. `resolve_model_ids: "omit"` — returns empty string when no `runtime` is set.
+4. Claude-native default — `model_profile` tier as alias (current default).
+5. `inherit` — propagates literal `inherit` for `Task(model="inherit")` semantics.
+
+**Backwards compatibility.** Setups without `runtime` set see zero behavior change — every existing config continues to work identically. Codex installs that auto-set `resolve_model_ids: "omit"` continue to omit the model field unless the user opts in by setting `runtime: "codex"`.
+
+**Unknown runtimes.** If `runtime` is set to a value with no built-in tier map and no `model_profile_overrides[<runtime>]`, GSD falls back to the Claude-alias safe default rather than emit a model ID the runtime cannot accept. To support a new runtime, populate `model_profile_overrides.<runtime>.{opus,sonnet,haiku}` with valid IDs.

+**Configuration:**
+- `workflow.drift_threshold` (integer, default `3`) — minimum new

+- `workflow.drift_action` (`warn` | `auto-remap`, default `warn`) —
+  warn-only or spawn `gsd-codebase-mapper` with `--paths` scoped to

+
+**What counts as drift:**
+- New directory outside mapped paths
+- New barrel export at `(packages|apps)/*/src/index.*`
+- New migration file (supabase/prisma/drizzle/src/migrations/…)
+- New route module under `routes/` or `api/`
+
+**Non-blocking guarantee:** any internal failure (missing STRUCTURE.md,
+git errors, mapper spawn failure) logs a single line and the phase
+continues. Drift detection cannot fail verification.
+
+**Requirements:**
+- REQ-DRIFT-01: System MUST detect the four drift categories from `git diff
+  --name-status last_mapped_commit..HEAD`
+- REQ-DRIFT-02: Action fires only when element count ≥ `workflow.drift_threshold`
+- REQ-DRIFT-03: `warn` action MUST NOT spawn any agent
+- REQ-DRIFT-04: `auto-remap` action MUST pass sanitized `--paths` to the mapper

 **Enable:** Set `workflow.discuss_mode` to `'assumptions'` via `/gsd-settings`.
 
 **How it works:**
+
 1. Reads PROJECT.md, codebase mapping, and existing conventions
 2. Generates a structured list of assumptions (tech choices, patterns, file locations)
 3. Presents assumptions for you to confirm, correct, or expand
 4. Writes CONTEXT.md from confirmed assumptions
 
 **When to use:**
+
 - Experienced developers who already know their codebase well
 - Rapid iteration where open-ended questions slow you down
 - Projects where patterns are well-established and predictable
 
 See [docs/workflow-discuss-mode.md](workflow-discuss-mode.md) for the full discuss-mode reference.
 
+### Decision Coverage Gates
+
+The discuss-phase captures implementation decisions in CONTEXT.md under a
+`<decisions>` block as numbered bullets (`- **D-01:** …`). Two gates — added
+for issue #2492 — ensure those decisions survive into plans and shipped
+code.
+
+**Plan-phase translation gate (blocking).** After planning, GSD refuses to
+mark the phase planned until every trackable decision appears in at least
+one plan's `must_haves`, `truths`, or body. The gate names each missed
+decision by id (`D-07: …`) so you know exactly what to add, move, or
+reclassify.
+
+**Verify-phase validation gate (non-blocking).** During verification, GSD
+searches plans, SUMMARY.md, modified files, and recent commit messages for
+each trackable decision. Misses are logged to VERIFICATION.md as a warning
+section; verification status is unchanged. The asymmetry is deliberate —
+the blocking gate is cheap at plan time but hostile at verify time.
+
+**Writing decisions the gate can match.** Two match modes:
+
+1. **Strict id match (recommended).** Cite the decision id anywhere in a
+   plan that implements it — `must_haves.truths: ["D-12: bit offsets
+   exposed"]`, a bullet in the plan body, a frontmatter comment. This is
+   deterministic and unambiguous.
+2. **Soft phrase match (fallback).** If a 6+-word slice of the decision
+   text appears verbatim in any plan or shipped artifact, it counts. This
+   forgives paraphrasing but is less reliable.
+
+**Opting a decision out.** If a decision genuinely should not be tracked —
+an implementation-discretion note, an informational capture, a decision
+already deferred — mark it one of these ways:
+
+- Move it under the `### Claude's Discretion` heading inside `<decisions>`.
+- Tag it in its bullet: `- **D-08 [informational]:** …`,
+  `- **D-09 [folded]:** …`, `- **D-10 [deferred]:** …`.
+
+**Disabling the gates.** Set
+`workflow.context_coverage_gate: false` in `.planning/config.json` (or via
+`/gsd-settings`) to skip both gates silently. Default is `true`.

+If you want tiered models on Codex without writing a large `model_overrides` block, set `runtime: "codex"` and pick a profile:

+{
+  "runtime": "codex",
+  "model_profile": "balanced"

+GSD will resolve each agent's tier (`opus`/`sonnet`/`haiku`) to the Codex-native model and reasoning effort defined in the runtime tier map (`gpt-5.4` xhigh / `gpt-5.3-codex` medium / `gpt-5.4-mini` medium). The Codex installer embeds both `model` and `model_reasoning_effort` into each agent's TOML automatically. To override a single tier, add `model_profile_overrides.codex.<tier>`. See [Runtime-Aware Profiles](CONFIGURATION.md#runtime-aware-profiles-2517).

+ * #2517 — Resolve the runtime-aware tier entry for (runtime, tier).
+ *
+ * Single source of truth shared by core.cjs (resolveModelInternal /
+ * resolveReasoningEffortInternal) and bin/install.js (Codex/OpenCode TOML emit
+ * paths). Always merges built-in defaults with user overrides at the field
+ * level so partial overrides keep the unspecified fields:
+ *
+ *   `{ codex: { opus: "gpt-5-pro" } }`           keeps reasoning_effort: 'xhigh'
+ *   `{ codex: { opus: { reasoning_effort: 'low' } } }` keeps model: 'gpt-5.4'
+ *
+ * Without this field-merge, the documented string-shorthand example silently
+ * dropped reasoning_effort and a partial-object override silently dropped the
+ * model — both reported as critical findings in the #2609 review.
+ *
+ * Inputs:
+ *   - runtime: string (e.g. 'codex', 'claude', 'opencode')
+ *   - tier:    'opus' | 'sonnet' | 'haiku'
+ *   - overrides: optional `model_profile_overrides` blob (may be null/undefined)
+ *
+ * Returns `{ model: string, reasoning_effort?: string } | null`.

+ *
+ * Four categories of drift element:
+ *   - new_dir    → a newly-added file whose directory prefix does not appear
+ *                  in STRUCTURE.md
+ *   - barrel     → a newly-added barrel export at

+ *   - migration  → a newly-added migration file under one of the recognized

+ *   - route      → a newly-added route module under a `routes/` or `api/` dir
+ *
+ * Each file is counted at most once; when a file matches multiple categories
+ * the most specific category wins (migration > route > barrel > new_dir).
+ *
+ * Design decisions (see PR for full rubber-duck):
+ *   - The library is pure. It takes parsed git diff output and returns a
+ *     structured result. The CLI/workflow layer is responsible for running
+ *     git and for spawning mappers.
+ *   - `last_mapped_commit` is stored as YAML-style frontmatter at the top of

+ *     to the file, survives git moves, and avoids a sidecar JSON.
+ *   - The detector NEVER throws on malformed input — it returns a
