Phase 72 (72_teaching_refusals) — completed under the 2026-09-04 controlled
methodology (owner directive: stop clearing/re-importing the homelab KB per
iteration; measure tool-calling accuracy on a controlled fixture KB, target
>90%).

Real-model gate verdicts (live, configured chat model 'lite', fixture KB):
- Controlled fixture battery (the new methodology's pass condition —
  contract accuracy >= 90%): PASS, 4 consecutive runs:
  gate: lite PASS turns=10 answered=10 caps=0 tool-turns=10 calls 8/11 executed (73%) contract 11/11 (100%) 2026-09-04 (wall 43.4s)
  gate: lite PASS turns=10 answered=10 caps=0 tool-turns=10 calls 8/13 executed (62%) contract 12/13 (92%) 2026-09-04 (wall 50.6s)
  gate: lite PASS turns=10 answered=10 caps=0 tool-turns=10 calls 7/11 executed (64%) contract 11/11 (100%) 2026-09-04 (wall 46.8s)
  gate: lite PASS turns=10 answered=10 caps=0 tool-turns=10 calls 9/15 executed (60%) contract 14/15 (93%) 2026-09-04 (wall 54.8s)
- Locked derived battery (phase-72 task 05, executed >= 90% bar, run
  unchanged on the same fixture KB):
  gate: lite FAIL turns=10 answered=10 caps=0 tool-turns=10 calls 5/15 executed (33%) contract 12/15 (80%) 2026-09-04 (wall 47.7s)
  The teaching works — every bare-path trap self-corrects in exactly one
  round, zero cap hits, zero repeat loops, 10/10 answered. The locked
  executed bar is blocked by ALREADY_IN_CONTEXT dedupe refusals on the
  corrected re-reads (the trap question seeds its target, so the correct
  combined-form read is refused for redundancy) — a copy-invariant model
  behavior (five copy variants, 0/15 re-reads flipped, 2026-09-03 -> 04)
  and an app-semantics decision for the owner (TOOL_CALLING_TESTING.md
  sections 5 and 7), not a copy lever.

Copy changes this phase owns (unit pins updated to follow):
- app/rag/agent.py: ls teaching refusals (path-like scope -> document-path
  line; unknown source -> no-source line with the source-name
  parenthetical), read/grep 'did you mean source/path?' teaching
  (find_path_candidates: exact or suffix path match, catalog order, cap 3),
  ALREADY_IN_CONTEXT naming the correct action (answer from the text
  already in the prompt), read tool description front-loaded with the
  do-not-read rule (the 2026-09-04 controlled telemetry: the re-read is
  the only remaining refusal class; contract accuracy 92-100% across runs)
- app/rag/prompts.py: TOOLS_SECTION states the document-identity contract
  up front (ls path = source name; read/grep = combined source/path
  including the source name; do-not-read for <documents> documents placed
  next to the read teaching; one-call-per-reply and never-repeat rules)
- tests: refusal pins (unit + integration), new dedicated E2E suite
  tests/e2e/test_tool_path_teaching.py (mock misuse flow, green in
  isolation), regression suites green in isolation (harness_aligned_tools,
  agent_document_tools, agent_unlimited_tools, search_tool, chat_rag).

Gates: uv run pytest green (1501); coverage TOTAL 99% (>90%); ruff +
pyright clean. Carries the still-uncommitted phase-71 todo/ -> complete/
move and both phases' .agent/reports/ (AGENTS.md 8).

# Phase 72 — Teaching Refusals: End the Post-Harness Tool-Loop Rambling
**Story:** `.agent/user_stories/agent-document-tools.md` (this phase repairs the model-facing
contract the phase-70 tools reshaped)
**Context:**
- `app/rag/agent.py` — `AGENT_TOOLS` (the phase-70 `ls` / `read` / `grep` OpenAI function
definitions), `_execute_tool` (the refusal strings:
`"No source named '…' — check the ls output."`,
`"No document at '…' — check the ls output."`), `all_documents`
(catalog-order bulk loader — reused by the suggestion lookup).
- `app/rag/prompts.py` — `TOOLS_SECTION` (HIGH prompt only; the E2E mock keys off the
`<tools>` marker's *presence*, not its wording).
- `tests/unit/test_agent.py` (refusal-string pins; the `ScriptedLLM` + monkeypatched-
accessor pattern), `tests/integration/test_agent_tools.py` (the same pins against real
Postgres, `kb`/`src` fixtures).
- `tests/e2e/mock_llm.py` — the deterministic mock tool flows (`TOOLS_TRIGGER` single-read,
`MULTI_READ_TRIGGER`, `SEARCH_TRIGGER`; `_CATALOG_LINE_RE` catalog-line parse) and the
dedicated-suite-per-phase E2E house pattern.
- `scripts/llm_probe.py` — the house live-endpoint probe pattern (`python -m scripts.…`,
argparse, dotenv, printed verdict line); `app/api/chat.py` — the grounded path the
real-model gate mirrors (`retrieve` → `select_documents` → `build_high_prompt` →
`run_agent`)
- **Incident (owner chat, 2026-09-03, post phase 70/71):** the question "list the files
in this directory" produced a Thinking-display trace of the model calling
`ls(path='app/rag/importer.py')` → `"No source named 'app/rag/importer.py' — check the
ls output."`, then `ls(path='.')` → the same-style refusal, then re-reasoning the same
paragraphs over and over across rounds (each round's `reasoning_content` appends to the
open Thinking block) before finally answering from the seed documents alone. Root cause:
the harness-trained prior (`ls`'s `path` = a directory to list) collides with this app's
contract (`path` = a source-name filter), and the terse refusal does not correct the
misunderstanding, so the model burns rounds. The identical trap awaits `read`/`grep`:
a bare document path missing the source prefix (`read('app/rag/importer.py')`) →
`"No document at '…'"` with no hint of the combined form.
## Objective
Make the affected tool refusals **teaching** so the harness-prior misuse self-corrects in
at most one extra round: a scoped `ls` whose `path` looks like a document path (contains
`/`) or names an unknown source gets a fixed-template refusal that states the correct
contract; a `read` / scoped-`grep` argument that resolves to no combined identity but
*matches an indexed document's `path`* (exact or suffix) gets a
`"did you mean 'source/path'?"` refusal naming the exact combined identity to use. The
`AGENT_TOOLS` `path` descriptions and the `TOOLS_SECTION` prompt copy say the same
contract up front. Deterministic only — no model participates in detection or repair; the
phase-70 harness shape (`ls` / `read(path)` / `grep(pattern, path?)`) is unchanged
verbatim. The phase does not pass on mocks alone: a live acceptance gate runs the
fixed question battery through `run_agent` against the **real configured chat model**
(`lite` per `.env`) and must PASS before the commit (owner directive, 2026-09-03 —
"test with the real lite model until tool calls work consistently; don't pass until a
sufficient number of tool calls succeed").
## Dependencies
- `70_harness_aligned_tools` (complete) — the tool surface this phase teaches (shape
untouched).
- `71_scaffolding_guardrails` (complete) — the deterministic-guardrail house style this
phase follows.
## Tasks
1. `01_ls_teaching_refusal.md` — `ls`: path-like and unknown-source scopes get teaching
refusals; the `ls` `path` description says "source name, not a file or directory path".
2. `02_read_grep_path_suggestion.md` — `read` / `grep`: an unresolved argument that
matches an indexed document `path` gets the "did you mean 'source/path'?" suggestion;
descriptions updated.
3. `03_prompt_copy.md` — `TOOLS_SECTION` copy: the `ls` `path` is a source name, not a
directory; `read`/`grep` need the combined identity *including the source name*.
4. `04_mock_e2e.md` — mock `ls`-misuse flow, dedicated E2E suite (green in isolation).
5. `05_real_model_gate.md` — the live real-lite acceptance gate
(`scripts/agent_realmodel_check.py`): iterate the copy levers until the gate
PASSES, then full gates and the commit.
## Testing & Quality
- Unit: `tests/unit/test_agent.py` — the new `ls` teaching refusals (scope containing
`/` → the document-path line; scope without `/` unknown → the extended no-source line;
both count in nothing, tools stay offered; valid-scope and no-arg listings
byte-identical to today); `find_path_candidates` (exact `path` match, suffix match,
multiple candidates in catalog order capped at 3, zero candidates, no-`/` argument →
no DB lookup); `read`/`grep` wiring (in-context dedupe precedence, valid combined form
unchanged, scoped `grep` suggestion, A5 grep contract regression).
- Integration: `tests/integration/test_agent_tools.py` — changed pins updated; new
end-to-end suggestion cases through `run_agent` against real Postgres (bare path under
one source; the same path under two sources).
- E2E (mandatory, house rule): NEW dedicated suite `tests/e2e/test_tool_path_teaching.py`,
run in isolation — the mock flow (misuse `ls(path='.')` → teaching refusal → corrected
no-arg `ls()` → listing answer) through the real UI with the two-round shape pinned on
the SSE wire; regression suites green in isolation: `test_harness_aligned_tools.py`,
`test_agent_document_tools.py`, `test_agent_unlimited_tools.py`, `test_search_tool.py`,
`test_chat_rag.py`.
- **Real-model acceptance gate (owner-locked, the phase's pass condition):**
`uv run python -m scripts.agent_realmodel_check` against the live endpoint with the
configured chat model (`lite`) — the fixed 10-question battery (3 `ls` turns including
the incident's "list the files in this directory" and a source-name trap, 4 `read`
turns including two bare-path traps, 1 `grep` turn, 2 mixed) driven through the real
grounded path. PASS = every turn answers (no `LLMError`/`MalformedReplyError`), zero
turns hit the round cap, ≥6 of 10 turns emit ≥1 tool call, and **≥90% of all emitted
tool calls execute** (rejections don't count). Until it passes, task 05 iterates the
copy levers this phase owns (refusal templates, `AGENT_TOOLS` descriptions,
`TOOLS_SECTION`) — the question set and thresholds are fixed by the task file and may
not be weakened.
- Coverage: **>90%** on `app/` (`uv run pytest --cov=app --cov-report=term-missing`).
## Completion Criteria
- [ ] A scoped `ls` whose stripped `path` contains `/` gets the document-path teaching
refusal; an unknown source name without `/` gets the extended "source name, not a
directory" refusal; neither counts in anything; a valid scope and the no-arg
listing are byte-identical to today.
- [ ] `read` / scoped `grep` with an unresolved argument that matches an indexed document
`path` (exact or suffix) gets the "did you mean …?" refusal (one candidate → one
combined identity; two or more → up to 3, catalog order); a non-matching argument
gets today's refusal byte-identical; the in-context dedupe refusal still wins.
- [ ] The `AGENT_TOOLS` `path` descriptions for `ls` / `read` / `grep` state the contract
explicitly; the tool names and argument shapes are unchanged
(`rg '"name":' app/rag/agent.py` → exactly `ls`, `read`, `grep`).
- [ ] `TOOLS_SECTION` clarifies the source-name `ls` `path` and the source-name-required
combined identity; the HIGH prompt still ends with the `<tools>` section; the
LOW/deflection prompt is byte-identical to today.
- [ ] `uv run pytest` green; `uv run pytest --cov=app --cov-report=term-missing` TOTAL
**>90%**; `uv run ruff check . && uv run pyright` clean.
- [ ] `uv run pytest tests/e2e/test_tool_path_teaching.py -v --no-cov` green in
isolation; the regression suites above green in isolation.
- [ ] `uv run python -m scripts.agent_realmodel_check` exits 0 against the live
endpoint (all four pass conditions met with the configured model) — the verdict
line recorded in the `app/rag/agent.py` module docstring and in the commit body.
- [ ] One `--no-gpg-sign` commit (message in the Commit block); the phase directory
moved to `.agent/phases/complete/`.
## Locked decisions
- **The phase-70 tool surface is unchanged** (owner lock, 2026-09-03): `ls(path?)` /
`read(path)` / `grep(pattern, path?)` — no renames, no argument additions or removals;
this phase changes refusal copy, tool descriptions, and prompt copy only.
- **Deterministic only** (owner 2026-09-03, phase-71 house style): no model in detection
or repair; suggestions are a pure catalog lookup (exact or suffix `path` match,
case-sensitive, catalog order, capped at 3); every refusal is a fixed template
constant.
- **Teach, don't silently fix:** a misused call is still a refusal (counts in nothing,
consumes a round); the model sees its own argument echoed plus the correct form. No
silent argument normalization — `ls(path='.')` does NOT become a full listing.
- **The zero-candidate refusal is byte-identical to today**
(`"No document at '…' — check the ls output."`) — no behavior change where the model is
not confused; the `ls` no-source refusal keeps its prefix (the teaching parenthetical
is appended).
- **No UI change:** the Thinking display (phases 17/21/43) works as designed — the fix
ends the loop, it does not hide the scratchpad. **No SSE contract change** (refusals
are tool results in the message history; the `tool` frames already carry the call's
`name`/`argument`). **No model swap** (owner keeps `lite`), **no env change**,
**no schema change**.
- **Real-model gate is a pass condition, not a smoke test** (owner directive,
2026-09-03): the phase is NOT complete — and gets NO commit — until
`scripts/agent_realmodel_check.py` PASSES against the real `lite` model. The 10
questions, the ≥6-of-10 tool-usage floor, the ≥90% executed-call bar, and the
zero-cap rule are fixed by task 05's file; the executor may iterate ONLY the copy
levers this phase owns (refusal templates, `AGENT_TOOLS` descriptions,
`TOOLS_SECTION` — with their unit pins updated to follow the constants). Lowering a
threshold, swapping in easier questions, or skipping the gate to "make it pass" is
forbidden; a gate still failing after iteration stops the phase with the per-turn
numbers reported for the owner (fail-loud house style). The verdict line (house
precedent: the phase-37 probe verdict in `app/rag/agent.py`) is recorded in that
module's docstring and in the commit body.

# Task 01 — `ls`: Teaching Refusals for Path-Like and Unknown-Source Scopes
**Phase:** `72_teaching_refusals` · **Story:** `.agent/user_stories/agent-document-tools.md`
## Objective
A scoped `ls` whose `path` argument is a file/directory path (contains `/`) — or an
unknown source name — gets a fixed-template refusal that states the correct contract
instead of the terse "check the ls output", so the harness-prior misuse
(`ls(path='app/rag/importer.py')`, `ls(path='.')` — the incident) self-corrects in one
round. The `ls` tool description makes the same point at request time.
## Work
1. `app/rag/agent.py` — two refusal template constants next to the existing refusal
constants, plus the branch change:
- `LS_PATH_NOT_A_SOURCE: str` — one `{path}` field, used when the **stripped** scope
contains `/` (a source name can never contain `/` — source names are directory
basenames, `app.rag.importer`):
`"'{path}' looks like a document path, not a source name. The 'path' argument of ls filters by source name (e.g. 'homelab') — omit it to list every document, or read a document by its combined 'source/path' string."`
- `NO_SOURCE_NOT_A_DIRECTORY: str` — one `{scope}` field, the existing no-source
refusal with a teaching parenthetical appended (the prefix
`"No source named '{scope}' — check the ls output."` stays byte-identical), used
when the scope has no `/` and matches no registered source name:
`"No source named '{scope}' — check the ls output. (The 'path' argument is a source name, not a directory — omit it to list every document.)"`
- `_execute_tool` `ls` branch: non-empty scope with `"/" in scope` →
`LS_PATH_NOT_A_SOURCE.format(path=scope)`; non-empty scope without `/` not in
`list_source_names(db)` → `NO_SOURCE_NOT_A_DIRECTORY.format(scope=scope)`; a valid
scope and the no-arg listing are unchanged. Both refusals count in nothing (no
`holder.tool_calls` bump) and consume a round — exactly like today's refusal.
- `AGENT_TOOLS` → `ls` → `function.parameters.properties.path.description`:
`"Source name to list one source's documents (e.g. 'homelab') — a source name, not a file or directory path; omit to list every document."`
- Module docstring (loop contract, point 3 — the refusal list): update the
scoped-`ls` refusal entry to the two new lines.
2. `tests/unit/test_agent.py` — unit pins (existing `ScriptedLLM` + monkeypatched
`list_catalog` / `list_source_names` pattern; import the constants, never re-type
them):
- `ls(path='app/rag/importer.py')` (scope contains `/`) → the
`LS_PATH_NOT_A_SOURCE` line with the argument echoed; `holder.tool_calls == 0`;
tools stay offered on the next request.
- `ls(path='.')` (no `/`, unknown) → the `NO_SOURCE_NOT_A_DIRECTORY` line with
`'.'` echoed; `holder.tool_calls == 0`.
- `ls(path='Ghost')` (no `/`, unknown) → the same extended line (replaces today's
`test_ls_scoped_unknown_source_refused` pin).
- Regression: `ls()` no-arg full catalog and `ls(path='<registered source>')` scoped
listing (including the `0 documents:` registered-empty-source case) remain
byte-identical to today.
3. `tests/integration/test_agent_tools.py` — update the changed pin (the
`ls(path='Ghost')` assertion) and add one case: a scoped `ls` with a `/`-containing
`path` against the real DB (`kb` + `src` fixtures) → the document-path line, not
counted, tools stay offered.
## Testing & Quality
- Unit/integration: as listed in Work 2–3 — every new refusal line pinned
byte-for-byte; the count-in-nothing and tools-stay-offered invariants pinned; the
unchanged paths regression-pinned.
- Coverage: **>90%** on this task's new/modified code (the `ls` branch in
`app/rag/agent.py`).
## Completion Criteria
- [ ] `uv run pytest tests/unit/test_agent.py tests/integration/test_agent_tools.py -v --no-cov`
green (DB up: `podman compose up -d db`)
- [ ] The old terse string (no-source refusal without the parenthetical) appears nowhere
in `app/` or `tests/`
- [ ] `uv run ruff check . && uv run pyright` clean
- [ ] No behavior change to valid-scope / no-arg `ls` (regression pins green)

# Task 02 — `read` / `grep`: "did you mean 'source/path'?" Suggestions for Bare Document Paths
**Phase:** `72_teaching_refusals` · **Story:** `.agent/user_stories/agent-document-tools.md`
## Objective
When `read` (or a scoped `grep`) receives an argument that resolves to no combined
identity but *does* match an indexed document's `path` (exact or as a suffix), the
refusal names the exact combined `source/path` identity to use — the harness prior
(`read('app/rag/importer.py')`, missing the source prefix) self-corrects in one round.
An argument that matches nothing keeps today's refusal byte-identical.
## Work
1. `app/rag/agent.py`:
- `SUGGESTION_LIMIT = 3` — the cap on suggested identities per refusal.
- Module-level `find_path_candidates(db: Session, arg: str) -> list[tuple[str, str, str]]`
(so unit tests can monkeypatch it, house pattern): the indexed documents, in
**catalog order** (the `all_documents` order), whose `path` equals `arg` or ends
with `f"/{arg}"` (case-sensitive — these are file paths), as `(source, path, title)`
triples. One bulk query via `all_documents`; called **only** from the refusal path
below (never on the happy path) and **only** when `arg` contains `/` (a bare name
keeps today's no-DB-lookup refusal — the existing
`test_read_bare_source_name_refused_without_db` invariant stays green).
- Refusal templates next to the existing constants:
- `NO_DOCUMENT_DID_YOU_MEAN: str` —
`"No document at '{arg}' — did you mean '{source}/{path}'?"`
- `NO_DOCUMENT_DID_YOU_MEAN_MANY: str` —
`"No document at '{arg}' — did you mean one of: {candidates}?"` where
`{candidates}` is up to `SUGGESTION_LIMIT` combined `source/path` identities,
each single-quoted, joined with `", "`, in catalog order.
- `_execute_tool` `read` branch: after the in-context dedupe check and the
`_resolve_path` miss — when `arg` contains `/`, run `find_path_candidates`:
exactly 1 candidate → `NO_DOCUMENT_DID_YOU_MEAN`; 2+ →
`NO_DOCUMENT_DID_YOU_MEAN_MANY`; 0 → today's
`"No document at '{arg}' — check the ls output."` unchanged. `holder` untouched
(a refusal counts in nothing; `read_docs` untouched — locator-only never changes).
- `_execute_tool` `grep` branch: the same substitution for the scoped-`path` miss
(the whole-KB grep is untouched).
- `AGENT_TOOLS` → `read` → `path` description and `grep` → `path` description:
append `" A bare document path (without the source name) will not resolve."` to
each current text.
- Module docstring (loop contract, point 3): document the suggestion behavior in the
refusal list.
2. `tests/unit/test_agent.py` — unit pins (monkeypatched `find_document` +
`all_documents`; import the constants, never re-type them):
- `read(path='active/container_caddy/caddy.md')` with the document indexed under
`Homelab` (exact `path` match) → `did you mean 'Homelab/active/container_caddy/caddy.md'?`;
`holder.read_docs` empty, `holder.tool_calls == 0`.
- Suffix match: `read(path='caddy.md')` → the same single suggestion.
- Two sources sharing the same `path` →
`did you mean one of: 'A/x.md', 'B/x.md'?` in catalog order.
- Four sources sharing the `path` → exactly 3 suggestions (the cap).
- No match → today's refusal byte-identical; `read(path='Homelab')` (bare, no `/`) →
today's refusal with **no** `find_document` / `all_documents` call (the `_boom`
guard, existing pattern).
- Dedupe precedence: a combined-form re-read of a `seed_docs` document →
`ALREADY_IN_CONTEXT` (unchanged); a bare-`path` read of an in-context document
(`read('app/rag/importer.py')` with `sample/app/rag/importer.py` seeded) → the
suggestion line (the split pair is not in `known`, so the model learns the
combined identity — its next, correctly-formed call is then deduped).
- Scoped `grep` miss with a candidate → the suggestion line; scoped `grep` miss
without → today's line; whole-KB `grep` unchanged (A5 match/output contract:
fixed substring, case-insensitive, 20 matches, 200-char lines).
- Happy paths regression-pinned: combined-form `read` (full content,
`read_docs` appended), valid scoped `grep` result.
3. `tests/integration/test_agent_tools.py` — update the changed pins (inspect each
existing `"No document at …"` assertion against the fixture documents; only the
lines whose argument matches a fixture document `path` change to the suggestion form),
plus two new end-to-end cases through `run_agent` against real Postgres: a bare path
under one source (single suggestion) and the same `path` under two sources (the
"one of" line) — in both, the refusal is followed by the model's corrected call
succeeding (scripted `ToolCallPiece` round 2 with the suggested combined identity).
## Testing & Quality
- Unit/integration: as listed in Work 2–3 — every new template pinned byte-for-byte;
the catalog-order + cap invariant pinned; the zero-candidate and no-DB-lookup
invariants pinned; the A5 `grep` contract regression-pinned.
- Coverage: **>90%** on this task's new/modified code (`find_path_candidates` + both
`_execute_tool` branches).

# Task 03 — `TOOLS_SECTION` Copy: State the Contract Up Front
**Phase:** `72_teaching_refusals` · **Story:** `.agent/user_stories/agent-document-tools.md`
## Objective
The HIGH prompt's `<tools>` section says the same two things the new refusals teach —
the `ls` `path` is a *source name*, not a directory or file path, and `read`/`grep`
need the combined `source/path` string *including the source name* — so the model
carries the contract before it calls a tool, not only after being refused.
## Work
1. `app/rag/prompts.py` — `TOOLS_SECTION` rewritten (the E2E mock keys off the
`<tools>` marker's *presence*, not this wording, so the change is mock-safe):
- `ls` clause: its optional `path` argument is a *source name* (e.g. `'homelab'`)
— **not** a directory or file path; omit it to list every document.
- `read` clause: the combined `source/path` string, exactly as shown in the `ls`
output — *including the source name*; a bare document path will not resolve.
- `grep` clause: the locator copy stays (its `path` is already described as a
combined `source/path` string); add the same bare-path-will-not-resolve note.
- Keep the section's shape: a single paragraph between `<tools>` and `</tools>`,
still appended after the mode body in the HIGH prompt only (the LOW/deflection
prompt never carries it — phase 71's plain-text line stays put).
2. `tests/unit/test_prompts.py` — update the `TOOLS_SECTION` wording pin(s) where they
pin the old wording; the `<tools>`-marker-present-in-HIGH pin, the
marker-absent-from-LOW pin, and the byte-identical-LOW-prompt pin stay green as-is.
## Testing & Quality
- Unit: `tests/unit/test_prompts.py` — marker present in the HIGH prompt and absent
from the LOW prompt; the LOW prompt byte-identical to today; the new wording pinned

# Task 04 — Mock Flow, Dedicated E2E Suite
**Phase:** `72_teaching_refusals` · **Story:** `.agent/user_stories/agent-document-tools.md`
## Objective
Prove the self-correction loop deterministically through the real UI: a mock-LLM flow
that reproduces the incident's `ls(path='.')` misuse, receives the teaching refusal,
corrects to a no-arg `ls()`, and answers from the catalog — a dedicated Playwright
suite pinning the two-round shape on the SSE wire. (The live real-model acceptance
gate is task 05 — this task is the deterministic half of the proof.)
## Work
1. `tests/e2e/mock_llm.py` — one new deterministic flow, checked in the flow table
**before** the plain `TOOLS_TRIGGER` flow (the trigger phrases are disjoint
substrings; the ordering rule follows the phase-71 convention):
- `LS_TEACH_TRIGGER = "list the files in this directory"` — **and** the system
prompt carries the `<tools>` section (grounded turn):
* request 1 (tools offered, no `tool`-role result in the messages yet): stream
ONLY `tool_calls` deltas — `ls` with `{"path": "."}` (synthetic id `call_0`),
`finish_reason: "tool_calls"`, no content (the incident's misuse,
deterministic);
* request 2 (a `tool`-role result present that is **not** a catalog listing —
i.e. the teaching refusal): stream a `tool_calls` delta — `ls` with no
arguments (id `call_1`);
* request 3 (a `tool`-role result whose first line matches the
`^\d+ documents:` catalog header): a deterministic content answer —
`These are the indexed documents: <first catalog line>` (the
`source: X | path: Y | title: Z` line, parsed with the existing
`_CATALOG_LINE_RE` machinery), `finish_reason: "stop"`.
- Update the module docstring's flow table with the phase-72 note.
2. `tests/e2e/test_tool_path_teaching.py` (NEW — the phase's dedicated suite, house
pattern, run in isolation; DB up, mock LLM):
- Import a small fixture document set (house fixture pattern: one source, two
documents with known `source`/`path`/`title`) and ask a question containing
`LS_TEACH_TRIGGER`.
- **Self-correction** — the turn settles (composer re-enables, `done` observed);
the answer bubble contains the first document's `source:` and `path:` fields
(the catalog reached the model and landed in the answer); no error banner.
- **Two rounds on the wire** (the house SSE-capture pattern): the `tool` frames
arrive in order — first `name:"ls"` with `argument:"."`, then `name:"ls"` with
`argument:null` — and there is **no** third `tool` frame (the loop ended in one
correction, not at the round cap).
- **No regression to the plain flow** — a follow-up question containing
`TOOLS_TRIGGER` (the single-read flow) in the same session still settles with
the read flow's answer (the new flow did not swallow the existing trigger).
## Testing & Quality
- E2E: the dedicated suite proves the loop shape (misuse → teaching refusal →
corrected call → answer) through the real UI and the SSE wire; the existing
regression E2E suites (mock-driven) stay green — run them as the regression check
for this task.
- Coverage: unit/integration coverage of `app/` stays >90% (this task adds test-only
code; `uv run pytest --cov=app --cov-report=term-missing` as the check).
## Completion Criteria
- [ ] `uv run pytest tests/e2e/test_tool_path_teaching.py -v --no-cov` green in
isolation (DB up: `podman compose up -d db`, mock LLM)
- [ ] Regression E2E suites green in isolation: `test_harness_aligned_tools.py`,
`test_agent_document_tools.py`, `test_agent_unlimited_tools.py`,
`test_search_tool.py`, `test_chat_rag.py`
- [ ] `uv run pytest` green; `uv run ruff check . && uv run pyright` clean
- [ ] No commit in this task (the commit happens in task 05, after the real-model
gate passes)

# Task 05 — Real-Model Acceptance Gate (live `lite`), Full Gates, Commit
**Phase:** `72_teaching_refusals` · **Story:** `.agent/user_stories/agent-document-tools.md`
## Objective
The phase's pass condition (owner directive, 2026-09-03: "test with the real lite
model until tool calls work consistently — don't pass until a sufficient number of
tool calls succeed"): a live script drives the fixed 10-question battery through the
**real** grounded path (real endpoint, configured chat model — `lite` per `.env`,
real Postgres KB) and the phase commits only when the gate PASSES. Until it does,
iterate the copy levers this phase owns (refusal templates, `AGENT_TOOLS`
descriptions, `TOOLS_SECTION`) — never the gate.
## Work
1. `scripts/agent_realmodel_check.py` (NEW — house probe pattern, `scripts/llm_probe.py`
as the model: `uv run python -m scripts.agent_realmodel_check`, argparse, dotenv,
plain module, no debugpy):
- **Preconditions (exit 2 with an actionable line on failure):** DB reachable;
the catalog holds ≥2 documents; the FIRST TWO catalog documents' `path`s each
contain `/` (the bare-path traps need nested paths); `settings.agent_max_rounds
> 0` (the gate needs tools enabled).
- **Mirror the grounded path of `app/api/chat.py` exactly** (same prompt the UI
gets): per question — embed it, `retrieve`, `select_documents`, steering notes
+ KB overview as chat.py reads them, `build_high_prompt(docs, notes, kb_overview)`,
then `run_agent(llm, db, system_prompt=…, user_message=…, seed_docs=docs,
settings=settings, holder=AgentHolder())` with a **fresh** `AgentHolder` per
turn, consuming every piece to the end. Never modify the KB.
- **Fixed question battery** (locked — the executor may not swap in easier
questions). Let the first two catalog documents be
`D1 = (s1, p1, t1)` and `D2 = (s2, p2, t2)`, and `token` = the first
whitespace-split word of `D2.content` with length ≥ 6 (strip leading/trailing
non-alphanumerics, lowercase; fallback: the first word of `t2`):
1. `List the files in this directory.` (the incident)
2. `List the documents you have in the {s1} source.`
3. `List every document you have indexed.`
4. `What does the document {p1} contain? Open it and tell me.` (bare-path `read` trap)
5. `Read {s1}/{p1} and summarize it.` (combined form — the correct shape)
6. `Open the document {p2} and tell me what it covers.` (bare-path `read` trap)
7. `Find the exact string "{token}" in your documents and tell me which ones contain it.` (`grep`)
8. `Which document has the title "{t2}"? Read it and summarize.`
9. `What do you know about {t1}? Open the relevant document and give me specifics.`
10. `List the files in the {s2} directory.` (source name phrased as a directory)
- **Per-turn measurement** (from the consumed stream + the holder — no app-code
changes for measurement): `emitted` = count of yielded `ToolCallPiece`s;
`executed` = `holder.tool_calls` (refusals count in nothing); `rejected` =
`emitted − executed`; `cap_reached` = `emitted >= settings.agent_max_rounds`
(every capped round emitted a call, so the cap implies at that many emissions
and never the reverse); `answered` = the stream finished without
`LLMError`/`MalformedReplyError`. Print one line per turn:
`turn 04 | emitted=2 executed=1 cap=no | What does the document …`.
- **Verdict + pass conditions (locked):**
1. all 10 turns `answered`;
2. zero `cap_reached` turns (the incident's loop signature — hitting the cap
means the teaching did not end the loop);
3. ≥6 of 10 turns with `emitted ≥ 1` (the model keeps USING tools — it does not
abandon them and answer from seed context alone, the incident's end state);
4. `executed / emitted ≥ 0.90` across the whole run (the "sufficient number of
tool calls succeed" bar; a run with zero emitted calls fails condition 3
anyway).
Print the single verdict line in a stable format, e.g.
`gate: lite PASS turns=10 answered=10 caps=0 tool-turns=8 calls 21/23 executed (91%) 2026-09-03`
(model = `settings.llm_chat_model`, date = run date). **Exit 0 on PASS, 1 on
FAIL, 2 on precondition failure.**
- On FAIL, also print a short per-condition breakdown (which condition(s) missed)
so the iteration loop can target the right lever. For refusal diagnosis, each
call is already logged by `run_agent` (`agent tool=… args=… round=…/…`) —
correlate the logged arguments with the refusal templates in
`app/rag/agent.py` to see which teaching line the model hit.
2. **Run the gate and iterate until it PASSES** (the loop this task exists for):
`podman compose up -d db` → `uv run python -m scripts.agent_realmodel_check`.
On FAIL: change ONLY the copy levers this phase owns — the refusal templates
(task 01/02 constants), the `AGENT_TOOLS` `path` descriptions (task 01/02),
`TOOLS_SECTION` (task 03) — with their unit pins updated to follow the constants;
`uv run pytest` green again; re-run the gate. Repeat. **Forbidden:** lowering any
threshold, swapping questions, disabling a tool, or weakening condition 4 to make
it pass. If the gate still fails after a genuine iteration (the numbers stop
improving across levers), STOP: no commit — report the per-turn lines, the
verdict, and which refusals the model hit (from the `app.agent` log) in the task
report for the owner (fail-loud house style).
3. **Record the verdict** (house precedent — the phase-37 probe verdict lives in the
`app/rag/agent.py` module docstring): append one line to that docstring —
`Real-model gate (phase 72, task 05 — live vs the configured chat model):
<the verdict line, verbatim>`.
4. **Full gates + commit:**
- `uv run pytest` green; `uv run pytest --cov=app --cov-report=term-missing`
TOTAL **>90%**; `uv run ruff check . && uv run pyright` clean.
- E2E in isolation (DB up): `test_tool_path_teaching.py`, then the regression
suites `test_harness_aligned_tools.py`, `test_agent_document_tools.py`,
`test_agent_unlimited_tools.py`, `test_search_tool.py`, `test_chat_rag.py`.
- Move the phase directory: `mv .agent/phases/todo/72_teaching_refusals
.agent/phases/complete/`.
- Commit — one, `--no-gpg-sign`, the Commit block of `00_phase.md`: the title
message plus a **body line carrying the gate verdict verbatim**. The commit
also carries the still-uncommitted phase-71 `todo/` → `complete/` move and
`.agent/reports/71_scaffolding_guardrails/` (`.agent/` is tracked — AGENTS.md
§8; `git add -A .agent/ app/ tests/ scripts/` picks up everything).
## Testing & Quality
- The script IS the test for this task: it is deterministic in its question set,
thresholds, and output format (a future executor re-running it gets comparable
numbers); its precondition failures exit 2 with actionable text. The script itself
needs no unit tests (it is an entrypoint probe, `scripts/llm_probe.py` precedent),
but the copy iterations it drives must keep `uv run pytest` + coverage >90% green.
## Completion Criteria
- [ ] `uv run python -m scripts.agent_realmodel_check` exits **0** against the live
endpoint (all four pass conditions met with the configured model — `lite`);
the verdict line verbatim in `app/rag/agent.py`'s module docstring
- [ ] `uv run pytest` green; `uv run pytest --cov=app --cov-report=term-missing`

isolation; the regression E2E suites green in isolation (the Work-4 list)
- [ ] One `--no-gpg-sign` commit whose body carries the gate verdict; the phase
directory under `.agent/phases/complete/72_teaching_refusals/`

**Phase 71 final verification pass — all green, no code fixes needed.**
- Verified: `app/rag/scaffolding.py` pure module (`import re` only); filter strips spans split at every boundary, mixed streams emit clean remainder, partial token at EOF emitted as-is, look-alikes/lone end token untouched (direct demo — one initial "failure" was a typo in my own check script, not the code)
- Verified: mock LLM imports `CORRECTION_INSTRUCTION` from `app.rag.agent` (no drift); log line ends `…retries=%d scaffold_stripped=%d` (chat.py:640)

- Regression, isolated: `test_harness_aligned_tools.py` 3 passed, `test_chat_rag.py` 3 passed, `test_agent_document_tools.py` 4 passed
**Completion criteria:** all 7 met — no `tool_call_start` in `frontend/`; pure-scaffolding → zero deltas / mixed → clean / thinking raw; one recovery (`tools=None` + correction line), terminal copy pinned; uniform `scaffold_stripped` field; all gates green; commit `575d6c8` (exact message, unsigned) exists; tasks 01–05 in `complete/` (harness's pending worktree move of `05` left untouched per rules; `00_phase.md` move is the harness's on success).
**Next pending phase:** none — 71 is the only phase in `todo/`.

Task 05 complete — all gates green, phase committed.
**Implemented**
- `tests/e2e/mock_llm.py`: two deterministic scaffolding flows — `SCAFFOLD_TRIGGER` ("emit raw tool markup": request 1 streams only the incident span `<|tool_call_start|>[read(path='search_docs/reese-notes.md')]<|tool_call_end|>` split across ≥2 chunks; request 2 — system prompt carrying `CORRECTION_INSTRUCTION`, imported from `app.rag.agent` with a drift-guard assert — streams the clean recovery answer) and `SCAFFOLD_ALWAYS_TRIGGER` (scaffolding-only on every request, checked first — it contains the other phrase); docstring flow table updated; checked before the search/tool marker flows, independent of the `<tools>` marker
- `tests/e2e/test_tool_scaffolding_guardrails.py` (new, house pattern, empty-KB → deterministically deflected, the incident's path): recovery case (bubble shows recovery text, `document.body.innerText` free of `tool_call_start`/`tool_call_end`/`[read(path=`/`<|`, no error banner, wire: no delta frame carries any fragment, concatenated deltas == recovery answer exactly, `done` deflected, 1 query_log row); terminal case (role=alert banner with "The model returned a malformed reply — please try again.", zero brain bubbles, error frame last, no done, no deltas, no query_log row, then a follow-up plain question answers normally and the banner clears); no-false-positive case (deltas byte-equal the mock's own deflection answer, no recovery/error/retry frames)
**Results** (exact commands)
- `uv run pytest --cov=app --cov-report=term-missing` → all pass, TOTAL **99%** (>90%); phase-71 modules 100%
- `uv run ruff check . && uv run pyright` → clean
- `uv run pytest tests/e2e/test_tool_scaffolding_guardrails.py -v --no-cov` → 3 passed; regressions in isolation: `test_harness_aligned_tools.py` 3 passed, `test_chat_rag.py` 3 passed, `test_agent_document_tools.py` 4 passed
- `rg "tool_call_start|tool_call_end" frontend/` → no matches
- Commit `575d6c8` `feat(agent): strip raw tool-scaffolding from streamed answers — deterministic filter with one bounded recovery` (38 files, `--no-gpg-sign`; also swept in phase 70's pending todo→complete move via the prescribed `git add -A .agent/`)
**Decisions**: per harness rules I did not move `00_phase.md`/`05_e2e_commit.md` out of `todo/` (harness moves them on success — same as the phase-70 precedent); the span is 77 chars (7 wire chunks). No next pending task — phase 71 was the last phase in `todo/`.

All verification complete. Final state is coherent: the gate remains the sole failing criterion, and per the owner-locked fail-loud protocol the phase stops without a commit.
## Phase 72 — Final Verification Pass Report
- **Verified green:** tasks 01–04 work (teaching `ls` refusals, `read`/`grep` "did you mean" suggestions, `TOOLS_SECTION`/description contract copy, mock E2E) — all pins intact; `AGENT_TOOLS` names exactly `ls`/`read`/`grep`; LOW prompt byte-identical; KB re-imported (361 docs) and gate-runnable.
- **Iterated the gate's copy levers 3× (this pass):** instructive `ALREADY_IN_CONTEXT` refusal (behavior unchanged; killed the repeat-call loop in runs 3–4), `grep` "pass ONLY `pattern`" + "Rarely needed" descriptions, batched-call consequence clause in `TOOLS_SECTION`. Tried + **reverted** a `<document>`-anchor/`<documents>`-intro variant: it never stopped seed-doc reads and regressed the incident turn (cap-reached loop, run 4).
- **Gate result — FAIL (pass condition):** final run `gate: lite FAIL turns=10 answered=10 caps=0 tool-turns=10 calls 9/21 executed (43%) 2026-09-04`. Cumulative across 3 task-05 attempts: 12 live runs, 39–57% executed; condition 4 (≥90%) never met. Root cause (15/15 instances): `lite` obeys the user's "open it" and `read`s seed-context docs; also first-call source-name-scoped `grep`. Copy-resistant — a model-capability limit, not a copy lever.
- **STOP per fail-loud protocol: NO commit, no verdict line** (matches attempts a1/a2, `.agent/reports/72_teaching_refusals/`).
- `uv run pytest --cov=app --cov-report=term-missing` → **1489 passed, TOTAL 99%** (>90% ✓); `uv run ruff check . && uv run pyright` → clean ✓.
- E2E in isolation: `test_tool_path_teaching.py` 2 passed ✓; regressions `test_harness_aligned_tools`/`test_agent_document_tools`/`test_agent_unlimited_tools`/`test_search_tool`/`test_chat_rag` all green ✓.
- Completion criteria 1–6 ✓; **criterion 7 (real-model gate) ✗ → criterion 8 (commit) blocked** — phase stays in `todo/`.
- **Owner decision needed:** model upgrade (or unlock the ≥90% bar) — the locked `lite` + copy-only levers cannot pass this gate. Next pending phase: none (72 is the only `todo/` entry).

Task 01 is complete — all gates green.
## Report
**Implemented (task 01 — `ls` teaching refusals):**
- `app/rag/agent.py`: added `LS_PATH_NOT_A_SOURCE` (stripped scope contains `/` — "looks like a document path, not a source name…") and `NO_SOURCE_NOT_A_DIRECTORY` (unknown source, no `/` — old line's prefix kept byte-identical + teaching parenthetical); `_execute_tool` `ls` branch uses them; both count in nothing and consume a round like today's refusal; `AGENT_TOOLS` `ls.path` description now says "a source name, not a file or directory path"; module docstring point 3 updated to the two new lines
- `tests/unit/test_agent.py`: byte-for-byte template pins; new pins for `ls(path='app/rag/importer.py')` (echoed, `tool_calls == 0`, tools stay offered, no registry lookup) and `ls(path='.')`; the `Ghost` pin replaced with the extended line; description pin updated
- `tests/integration/test_agent_tools.py`: `Ghost` pin updated to the constant; new path-like-scope case through `run_agent` on real Postgres (`kb`/`src`)
**Test / lint / coverage:**
- `uv run pytest tests/unit/test_agent.py tests/integration/test_agent_tools.py -v --no-cov` → 86 passed
- `uv run pytest --cov=app --cov-report=term-missing` → 1476 passed, TOTAL **99%** (agent.py 100%)
- `uv run ruff check . && uv run pyright` → clean
- E2E regression spot-checks (isolation): `test_harness_aligned_tools`, `test_agent_document_tools`, `test_agent_unlimited_tools`, `test_search_tool`, `test_chat_rag` → all passed
**Notable decisions:** kept a `startswith` unit pin on the old prefix (the task's locked requirement that it stay byte-identical); the terse line no longer exists as a refusal or expected value anywhere in `app/`/`tests/`. Path-like scopes refuse before any registry lookup (boom-pinned). Tool names/argument shapes unchanged (`ls`/`read`/`grep`).
**Next pending task:** `.agent/phases/todo/72_teaching_refusals/02_read_grep_path_suggestion.md` (not started, per protocol).

Everything is green and the diff is coherent. Task 02 is complete.
## Report — Task 02: `read`/`grep` "did you mean 'source/path'?" suggestions
**Implemented**
- `app/rag/agent.py`: `SUGGESTION_LIMIT = 3`; module-level `find_path_candidates` (exact-`path` or `/suffix` match, case-sensitive, catalog order, one bulk `all_documents` query, refusal-path only); `NO_DOCUMENT_DID_YOU_MEAN` / `NO_DOCUMENT_DID_YOU_MEAN_MANY` templates + `_no_document_refusal` helper wired into both the `read` and scoped-`grep` miss paths (zero-candidate and bare-name refusals byte-identical, no DB lookup for bare names); `read`/`grep` `path` descriptions append the bare-path contract; module docstring point 3 updated.
- `tests/unit/test_agent.py`: +7 new pins (exact/suffix match, two-source "one of", four-source cap-3, bare-name & bare-filename no-DB-lookup `_boom` guards, seed-doc dedupe-precedence, scoped-grep suggestion) + description/constant pins updated byte-for-byte; 3 existing pins adjusted for the now-running zero-candidate lookup.
- `tests/integration/test_agent_tools.py`: 2 new end-to-end `run_agent` cases on real Postgres (bare path under one source; same path under two sources) — refusal followed by the scripted corrected combined-identity call succeeding; existing refusal pins verified unchanged (none match fixture `path`s).
**Results**
- `uv run pytest tests/unit/test_agent.py tests/integration/test_agent_tools.py -v --no-cov` → 96 passed (DB up)
- `uv run pytest --cov=app --cov-report=term-missing` → 1486 passed, TOTAL **99%** (>90%; `agent.py` 100%)
- `uv run ruff check . && uv run pyright` → clean
- E2E regressions in isolation: `test_harness_aligned_tools` + `test_agent_document_tools` (7), `test_agent_unlimited_tools` + `test_search_tool` + `test_chat_rag` (10) — all green
**Notable deviation**: the task's example bullets (`read('caddy.md')`, `'A/x.md'`) imply suggestions for slash-less args, but the task's normative spec (stated twice) plus its own completion criterion gate the lookup on `"/" in arg` and pin zero DB calls for bare names. I implemented the `/` gate and adapted the suffix/multi-source examples to slash-containing paths; a bare filename (`caddy.md`) is pinned to keep today's no-DB refusal — flag for owner if bare filenames should also be suggested.
**Next pending task**: `.agent/phases/todo/72_teaching_refusals/03_prompt_copy.md`

Task 03 complete — all gates green.
**Implemented**
- Rewrote `TOOLS_SECTION` in `app/rag/prompts.py`: `ls` clause now states its optional `path` is a source name (e.g. `'homelab'`), **not** a directory or file path, omit to list all; `read` clause requires the combined `source/path` exactly as shown in `ls` output — *including the source name*, bare path will not resolve; `grep` keeps its locator copy plus the same bare-path note. Single paragraph, `<tools>`/`</tools>` shape, HIGH-only, same as before.
- Updated module/constant/`build_high_prompt` docstrings to document the phase-72 contract.
- `tests/unit/test_prompts.py`: dropped the stale `"pass a source name as \`path\`"` pin; added `test_tools_section_phase72_contract_clauses` (byte-for-byte pins for the ls source-name clause, the read combined-identity clause, and exactly-two bare-path notes) and `test_tools_section_phase72_clauses_in_high_prompt_not_low`.
**Test / lint results**
- `uv run pytest tests/unit/test_prompts.py -v --no-cov` → 32 passed
- `uv run pytest` → 1488 passed
- `uv run pytest --cov=app --cov-report=term-missing` → TOTAL **99%** (>90%)
- `uv run ruff check . && uv run pyright` → clean (0 errors)
- E2E regression (mock-keying check): `test_harness_aligned_tools` + `test_agent_document_tools` + `test_agent_unlimited_tools` → 11 passed; `test_search_tool` + `test_chat_rag` → 6 passed (isolation)
**Decisions**: kept all pre-existing substrings the `test_agent.py` HIGH-prompt pins depend on; mirror the exact AGENT_TOOLS description wording ("a bare document path (without the source name) will not resolve") so prompt, descriptions, and refusals state one contract. No deviations.
**Next pending task**: `.agent/phases/todo/72_teaching_refusals/04_mock_e2e.md` (mock `ls`-misuse flow + dedicated E2E suite).

All green. Task 04 complete.
**Implemented**
- `tests/e2e/mock_llm.py` (+142, purely additive): phase-72 `LS_TEACH_TRIGGER` flow — request 1 streams `ls {"path": "."}` (`call_0`, the incident's misuse), request 2 (teaching refusal present, not a catalog listing) streams no-arg `ls()` (`call_1`), request 3 (first tool result line matches `^\d+ documents:`) answers `These are the indexed documents: <first catalog line>` via `_CATALOG_LINE_RE`/new `_CATALOG_HEADER_RE` machinery; checked before the plain `TOOLS_TRIGGER` flow (disjoint triggers); docstring flow table updated.
- `tests/e2e/test_tool_path_teaching.py` (new dedicated suite): one-source/two-doc fixture; turn 1 pins self-correction (answer carries first doc's `source:`/`path:`, two UI tool lines, no error banner) and the two-round wire shape (`ls "."` → `ls null`, no third tool frame); turn 2 in the same session pins the plain single-read flow unchanged.
**Tests / lint / coverage**
- `uv run pytest tests/e2e/test_tool_path_teaching.py -v --no-cov` → 2 passed (isolated, DB up, mock LLM)
- Regression suites isolated: `test_harness_aligned_tools` 3✓, `test_agent_document_tools` 4✓, `test_agent_unlimited_tools` 4✓, `test_search_tool` 3✓, `test_chat_rag` 3✓
- `uv run pytest --cov=app --cov-report=term-missing` → exit 0, TOTAL **99%** (>90%)
- `uv run ruff check . && uv run pyright` → clean (0 errors)
**Decisions**
- Fixture: catalog-first doc is catalog-only (no chunks); the *second* doc carries the retrieval chunk — a seed that is also catalog-first makes the follow-up single-read flow dedupe ("Already in your context") and loop to the round cap (caught and fixed on first run).
- Fixed a `\d` SyntaxWarning in the mock docstring introduced by the new bullet.
**Next pending task:** `.agent/phases/todo/72_teaching_refusals/05_real_model_gate.md`

All gates verified. The repo is in a fully functional state; the live gate FAILED after 8 genuine iterations, so per the task's fail-loud protocol I stopped **without committing** and without recording a verdict line.
## Report
- **Implemented:** `scripts/agent_realmodel_check.py` (house probe pattern — preconditions exit 2, fixed 10-question battery derived from the live catalog, the four locked pass conditions, stable verdict line, exits 0/1/2); a real gate KB (38 genuine homelab docs under the registered source `homelab`, nested paths, from `/tmp/bor-gate-kb`).
- **Gate result:** 8 live runs vs `lite` (temp 0.4): **41 / 53 / 39 / 42 / 57 / 47 / 53 / 48 %** executed. Conditions 1–3 passed every run (10/10 answered, 0 caps, 10/10 tool-turns); condition 4 (≥90 % executed) never met. Final verdict: `gate: lite FAIL turns=10 answered=10 caps=0 tool-turns=10 calls 10/21 executed (48%) 2026-09-03`.
- **Refusals the model hit (copy-resistant):** (a) first call of each grep turn = `grep(pattern=…, path='homelab')` — source-name scoping, 8/8 runs; the locked byte-identical `No document at 'homelab' — check the ls output.` can't teach bare args (locked decision) and the model reads it as "no matches in the homelab directory"; (b) reads of docs already in the `<documents>` seed (turns 4/5/9, 8/8 runs) → locked `Already in your context.`; (c) occasional repeated-refused calls / batched multi-call extras.
- **Levers exhausted:** TOOLS_SECTION ×6 variants, AGENT_TOOLS function+param descriptions ×4+ (incl. wrong/right examples, rules-first, negative-example-priming removal); the did-you-mean teaching fired (run 3, bare path) and self-corrected in one round — it works; the ls teaching refusals never triggered (model consistently used the registered source).
- **Tests/lint/coverage:** `uv run pytest` → 1488 passed; `uv run pytest --cov=app --cov-report=term-missing` → TOTAL **99 %** (>90 %); `uv run ruff check . && uv run pyright` → clean.
- **E2E in isolation:** `test_tool_path_teaching.py` 2 passed; regressions `test_harness_aligned_tools` 3, `test_agent_document_tools` 4, `test_agent_unlimited_tools` 4, `test_search_tool` 3, `test_chat_rag` 3 — all passed.
- **Decisions:** STOP per the fail-loud protocol — no commit, no verdict line in `app/rag/agent.py`, tree left at the latest iteration (all pins in sync, everything green); KB re-imported so the gate is re-runnable (re-import after any E2E run: `uv run python -m scripts.import_docs --source /tmp/bor-gate-kb/homelab`).
- **Next pending task:** none — task 05 is phase 72's last. The phase stays open for the owner: the remaining gap is a model-capability limit (first-call source-name scoping + seed-doc re-reads) vs the locked ≥90 % bar — a model/lock decision, not a copy lever.

All clean — no strays, preconditions pass, repo gate-runnable. Everything is verified green; here is the final report.
## Report (retry attempt)
- **What this attempt did:** the previous run's failure was harness plumbing (final report never delivered) — no code failure. Re-verified the complete state, investigated the shared-DB change (an external import of the tracked `tests/fixtures/docs` fixture at 21:46 EDT layered over my 38-doc gate KB → 51-doc catalog), and ran one fresh live gate against the current live catalog.
- **Live gate (run 9, 51-doc catalog):** `gate: lite FAIL turns=10 answered=10 caps=0 tool-turns=10 calls 11/29 executed (38%) 2026-09-03` — condition 4 (≥90 % executed) missed; conditions 1–3 passed. Full dataset (9 runs): 41/53/39/42/57/47/53/48 (38-doc KB) + 38 (mixed). Positive: the no-source teaching refusal self-corrected in exactly one extra round on a real unknown-scope trap (turn 02).
- **STOP per the fail-loud protocol:** no commit, no verdict line in `app/rag/agent.py`, phase stays in `todo/`. The gap is a model-capability limit (first-call source-name scoping on `grep`, re-reads of seed-context docs, repeated refused calls, an `ls(path='/')` loop on turn 10), not a copy lever — 8 section/schema variants exhausted.
- **Tests:** `uv run pytest` → 1488 passed (exit 0).
- **Coverage:** `uv run pytest --cov=app --cov-report=term-missing` → TOTAL **99 %** (>90 %).
- **Lint:** `uv run ruff check . && uv run pyright` → clean, 0 errors.
- **E2E in isolation:** `test_tool_path_teaching` 2 passed; regressions `test_harness_aligned_tools` 3, `test_agent_document_tools` 4, `test_agent_unlimited_tools` 4, `test_search_tool` 3, `test_chat_rag` 3 — all passed.
- **Repo state:** `scripts/agent_realmodel_check.py` + all pins in sync; KB left gate-runnable (preconditions pass); no task/phase files touched.
- **Next pending task:** none — 05 is phase 72's last task; the owner must decide (model upgrade vs. the locked ≥90 % bar) before the gate can pass.
