 ## Workflow
 
-Batch/join dependency-free steps; serialize only true dependencies while still covering every listed concern.
+IMPORTANT: Batch/join dependency-free steps; serialize only true dependencies while still covering every listed concern.
+
+Modes: Use `exploration_mode` to control cost and depth. Default is `scan` for backward compatibility.
+
+- `scan` — Quick keyword/pattern match, top N results. Low cost. No relationship mapping.
+- `deep` — Full semantic + grep + relationship mapping. High cost. Use for architecture/impact analysis.
+- `audit` — Inventory/checklist style. Low-medium cost. Lists what exists without deep tracing.
+- `trace` — Follow a specific call/data chain end-to-end. Medium cost. Limited depth hops.
+- `question` — Targeted lookup for a concrete question. Low cost. Returns focused answer.
 
 - Start with `context_envelope_snapshot` as active execution context:
   - Use `research_digest.relevant_files` as the initial file shortlist.
-  - Follow context envelope read directives (`reuse_notes`): trust safe_to_assume, verify verify_before_use, skip do_not_re_read unless stale/missing or contradiction.
+  - Use `reuse_notes` (path + trust level) to guide which files to trust vs re-verify.
   - Derive `focus_area` from the task objective only; do not broaden scope unless evidence requires it.
+- Determine mode from `task_definition.exploration_mode`:
+  - Default: `scan` if not specified (preserves backward compatibility)
+  - Read budget controls from `task_definition`: `max_searches`, `max_files_to_read`, `max_depth`
 - Research Pass — Objective Aligned Pattern discovery:
   - Identify focus_area strictly from the task's objective.
   - Discovery via semantic_search + grep_search, scoped to focus_area.
-  - Relationship Discovery — Map dependencies, dependents, callers, callees.
+  - Conditional Relationship Discovery:
+    - `scan`/`question`/`audit` → skip relationship mapping (callers/callees/dependents)
+    - `trace` → map only the specific chain requested, respecting `max_depth`
+    - `deep` → full relationship discovery (default behavior)
   - Calculate confidence.
-- Early Exit:
-  - If confidence ≥ 0.70 → skip relationships + detailed → Synthesize Phase.
-  - If decision_blockers resolved AND confidence ≥ 0.60 AND no critical open questions → early exit.
-  - Else → continue.
+- Early Exit — in order of priority:
+  1. Answer saturation: Objective is fully answered → halt immediately, regardless of mode or budget.
+  2. Mode confidence threshold reached → halt.
+  3. Budget exhausted → halt with current findings and note `budget_exhausted: true` in output.
+  4. Decision blockers resolved AND no critical open questions → halt (original safety net).
+  - Budget exhaustion: If `max_searches` or `max_files_to_read` reached before confidence threshold, exit with current findings and note budget exhaustion in output.

+- Include `workflow_complexity_hint` only when relevant to assessment or Phase 0 classification.
+- Include `budget` only when budget was constrained, exhausted, or useful for auditing.
+- Include `fail` only when `status` is `failed` or `needs_revision`.
+- Use `evidence` for all modes instead of separate `matches`, `inventory`, `trace`, and `findings`.
+- Keep `evidence` to the top 3-8 most important items unless the task explicitly asks for inventory.
+- `workflow_complexity_hint` is advisory only. The orchestrator decides final `workflow_complexity`.

 ## Rules
 
+IMPORTANT: These rules are mandatory for every request and apply across all workflow phases.

 ### Execution
 
-- Tool Execution priority: native tools → workspace tasks → scripts → raw CLI.
-- Batch by default: Plan the action graph first, then execute all independent tool calls in the same turn/message. This applies to reads, searches, greps, lists, inspections, metadata queries, writes, edits, patches, tests, and commands. Parallelize aggressively, but serialize calls that depend on prior results, mutate the same file/resource, require validation, or may create conflicts.
-- Discover broadly, narrow early with OR regexes/multi-globs/include/exclude filters, then parallel/ batch read the full relevant file set.
-- Execute autonomously; ask only for true blockers.
-- Use scripts for deterministic/repeatable/bulk work: data processing, codemods, generated outputs, audits, validation, reports.
-  - Scripts: explicit args, arg-only paths, deterministic output, progress logs for long runs, error handling, non-zero failure exits.
-  - Test on sample/small input before full run.
+- **Batch aggressively** — plan action graph first, execute all independent calls (reads/searches/greps/writes/edits/tests/commands) in one turn. Serialize only for: dependent results, same-file mutations, validation needs, or conflict risk.
+- **Execution** — workspace tasks → scripts → raw CLI. Exploration/editing etc: prefer native tools.
+- **Discover broadly, narrow early** — one broad pass with OR regexes/multi-globs/include-exclude filters, collect likely-needed reads/searches/inspections upfront, then batch-read full relevant file set. No drip-feeding; no repeated narrow loops.
+- **Execute autonomously** — ask only for true blockers. Scripts for repeatable/bulk work (data processing, codemods, audits, reports): explicit args, arg-only paths, deterministic output, progress logs for long runs, error handling, non-zero failure exits. Test on small input first. Retry transient failures 3×.
+- Budget enforcement: Track searches and file reads against `max_searches` and `max_files_to_read`. Halt exploration and return current findings when budget exhausted.
 
 ### Constitutional
 
-- Evidence-based—cite sources, state assumptions.
-- Hybrid: semantic_search+grep_search.
