+## Phase 70 — Harness-Aligned Tools: verification report
+
+**Verified (final pass — all 5 tasks already complete in `complete/`):**
+- `AGENT_TOOLS` = exactly `ls`(path?) / `read`(path) / `grep`(pattern, path?); `rg "list_documents|read_document|search_documents" app/` → no matches
+- `read` splits combined `source/path` at first slash, full content (A7); `grep` locked A5 (fixed substring, case-insens., 20×200, locator-only); `ls` prints `source: X | path: Y | title: Z`
+- SSE `tool` frames: new names; `argument` = the single string passed (`grep`→pattern, else path) or null
+- Kill switch (`MAX_ROUNDS=0` → one `tools=None` request) and LOW/deflected byte-identity pinned by unit tests and green
+- `TOOLS_SECTION` rewritten for the new surface; frontend `read`/`grep`/`ls` render (old names still render for persisted chats); README §"Agent document tools (ls + read + grep)" updated
+
+**Gates (exact commands):**
+- `uv run pytest --cov=app` → exit 0, all pass; TOTAL coverage **99%** (>90%)
+- `uv run ruff check . && uv run pyright` → "All checks passed!" / "0 errors"
+- `uv run pytest tests/e2e/test_harness_aligned_tools.py -v --no-cov` → **3 passed** (ls→read, grep→read, wire-argument rule)
+- Isolated regressions: `test_agent_document_tools` **4 passed**, `test_agent_unlimited_tools` **4 passed**, `test_search_tool` **3 passed**, `test_chat_rag` **3 passed**
+- Commit `801639e` exists with the exact Commit-block message; phase dir in `.agent/phases/complete/`
+
+**Deviations:** none — no code changes required this pass.
+**Next pending phase:** `71_scaffolding_guardrails` (in `todo/`).

+Done — the empty `.err` is a harness runtime artifact (tracked-report convention, same as prior phases); working tree is clean.
+
+**Phase 70, task 05 complete**
+
+- `tests/e2e/mock_llm.py`: deterministic flows now emit `ls` (no args, `call_0`), `read` with the **combined** `source/path` (mock joins the two catalog fields — only parse change), `grep` with `pattern`; docstrings + phase-70 notes updated
+- Existing E2E suites updated to new frames: `test_agent_document_tools.py` (`ls`→`read`), `test_agent_unlimited_tools.py` (multi-read `ls`+2×`read`), `test_search_tool.py` (`grep` + pattern argument)
+- NEW `tests/e2e/test_harness_aligned_tools.py` (3 tests): READ flow (ls line → 📄 Reading line → quoted answer → done.sources incl. read doc → no raw `<|…|>`/`tool_call` markup in DOM), SEARCH flow (🔎 Searching for sentinel → answer), wire argument rule across both flows (ls→null, read→combined path, grep→pattern; names ⊆ {ls, read, grep})
+- README agent-tools section rewritten for `ls`/`read(path)`/`grep(pattern, path?)` (combined identity + A5 locator semantics); `.env.example` header comment refreshed
+- Old-name cleanup so the rg criterion holds: `app/api/docs.py` route fn → `list_indexed_documents`, `app/rag/llm.py` docstrings, `test_llm_client.py`, `test_llm_stream_teardown.py`, `test_sse_events.py`, `test_mock_tool_flow.py`, `test_api.py` docstring. Remaining matches: only the explicitly-marked legacy frontend branches/pins + the marked legacy-chat persistence pin + the mandated "old names absent" regression pins from tasks 01–02
+
+**Gates (all green):**
+- `uv run pytest` → exit 0; `uv run pytest --cov=app --cov-report=term-missing` → TOTAL **99%** (>90%)
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors
+- E2E in isolation: `test_harness_aligned_tools` 3 passed, `test_agent_document_tools` 4, `test_agent_unlimited_tools` 4, `test_search_tool` 3, `test_chat_rag` 3
+
+**Decisions:** mock `_tool_flow` tuple kept `(source, path)`; the join happens at the wire-emission point (keeps `test_mock_tool_flow.py` pins valid). `.env.example` included in the commit for atomicity (not in the block's path list, but task 05 touched it). Phase-dir move left to the harness per executor rules.
+
+**Commit:** `801639e feat(agent): align the document tools with the harness-trained shape — ls, read(path), grep(pattern, path?)` (55 files, `--no-gpg-sign`)
+
+**Next pending:** `71_scaffolding_guardrails/01_filter.md`

+Task complete — all criteria green.
+
+**Implemented**
+- `app/rag/scaffolding.py`: pure module (`import re` only) with `SCAFFOLD_PATTERNS` (observed span + 2 standalone siblings, non-greedy span) and `ScaffoldingFilter` — streaming state machine: `feed()` strips leftmost-complete matches repeatedly, holds the live tail (open span or longest proper-prefix suffix of the 3 opening literals), `flush()` emits the tail as-is (pinned EOF choice), `stripped_chars` read-only property.
+- `tests/unit/test_scaffolding_filter.py`: 61-test matrix — span at every start-token split offset (0..19) + mid-span/end-token splits, multi-span, standalone tokens (alone/embedded/char-by-char), look-alikes verbatim, partial markers at EOF, exact surrounding-text preservation.
+
+**Results**
+- `uv run pytest tests/unit/test_scaffolding_filter.py -v --no-cov` → 61 passed
+- `rg "import (os|sys|logging|app)" app/rag/scaffolding.py` → no matches
+- `uv run pytest --cov=app` → 1448 passed; `app/rag/scaffolding.py` 100%, TOTAL 99% (>90%)
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors
+
+**Decisions** — open-span defined as "start with no end token *after* it" (prevents scaffolding leak when a lone end token precedes a start); repeated leftmost-strip loop pins spec behavior where removing one match can expose another. No deviations.
+
+**Next pending task:** `02_llm_integration.md` (wire filter into `chat_stream`/`chat_stream_retried`).

+Task 02 complete. All gates green.
+
+**Implemented**
+- `app/rag/llm.py`: `chat_stream(..., scaffolding: ScaffoldingFilter | None = None)` — content deltas fed through the caller-owned filter (empty clean result yields nothing), thinking never filtered, `None` keeps the byte-identical raw path; `flush()` tail is yielded as a content piece **before** tool-call materialization; phase-48 teardown untouched. `chat_stream_retried(..., scaffolding=None)` forwards the same filter to every attempt (safe by construction — a restart only happens pre-piece, i.e. filter never fed).
+- Tool materialization unified to a single post-loop emission point (the old in-loop `finish_reason="tool_calls"` early emission was removed) so the flushed tail always precedes `ToolCallPiece`s; identical wire behavior for all real/fixture stream shapes.
+- Tests: 7 new `chat_stream` filter tests + 2 retry pass-through tests in `tests/unit/test_llm_client.py` (span mid-stream, split across chunks, pure-scaffolding → zero pieces, thinking raw, `None` raw pin, flush-before-tools order, abandon-with-filter teardown, filter forwarded to every attempt, unfed-filter reuse).
+- Added the `scaffolding` kwarg to the five other `chat_stream` fakes (test_agent, test_chat_gate, test_agent_tools, test_chat_api) — required interface maintenance for the retry primitive to forward it.
+
+**Results**
+- `uv run pytest tests/unit/test_llm_client.py tests/unit/test_llm_stream_teardown.py -v --no-cov` → 60 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → 1457 passed; `app/rag/llm.py` 100%, TOTAL 99% (>90%)
+- `uv run ruff check . && uv run pyright` → clean
+- E2E regressions in isolation: `test_harness_aligned_tools` (3), `test_agent_document_tools` (4), `test_chat_rag` (3) → all passed
+
+**Decisions:** single post-loop tool-materialization point (simpler; pins the content-before-tools order at both former emission points); no commit — the phase commit belongs to task 05.
+
+**Next pending task:** `.agent/phases/todo/71_scaffolding_guardrails/03_recovery_policy.md`

+All green. Task 03 is complete.
+
+**Implemented**
+- `app/rag/agent.py`: `CORRECTION_INSTRUCTION` (verbatim constant), `MalformedReplyError(LLMError)`, `AgentHolder.scaffold_stripped`; `run_agent` now runs every request (rounds, forced final, recovery) through a fresh `ScaffoldingFilter`, logs one capture warning per stripped span (200-char truncation), and on a scaffolding-only no-calls round runs exactly one `tools=None` recovery with the correction folded into the single system message; a second empty reply raises `MalformedReplyError`
+- `app/api/chat.py`: deflected path uses a turn filter + extracted `_pump` piece loop, one bounded recovery when the filter wiped the reply, `MalformedReplyError` caught before the generic `LLMError` (dedicated error copy, no `done`/`query_log`), log line ends `…retries=N scaffold_stripped=N`
+- `app/rag/scaffolding.py`: `stripped_spans` (allowed by task); tests: 10 new unit (grounded matrix) + 3 new integration (deflected matrix), fakes now feed the filter like the real client
+
+**Results**
+- `uv run pytest tests/unit/test_agent.py tests/integration/test_chat_api.py -v --no-cov` → 94 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → green, TOTAL **99%** (>90%; all touched files 100%)
+- `uv run ruff check . && uv run pyright` → clean
+- E2E regressions in isolation: `test_harness_aligned_tools.py` (3 passed), `test_chat_rag.py` + `test_agent_document_tools.py` (7 passed)
+
+**Decisions**
+- Task's message formula conflicted with the locked "single system message" decision — implemented the locked one (replace original system msg with folded correction, history intact), pinned by unit tests
+- Forced-final request is filtered too; scaffolding-only final settles `MalformedReplyError` (no recovery after it — at most one per turn)
