Greptile Summary

This PR introduces a sentence-level archetype-based behavioral extraction pipeline as the primary extraction path, replacing the previous word-diff approach. It adds 12 correction archetypes (behavioral_extractor.py), cross-session pattern tracking with severity-weighted graduation scoring (meta_rules_storage.py), wires the new extractor into the core correction flow (_core.py), and backs everything with 12 new e2e pipeline tests.

Key changes:

  • behavioral_extractor.py — New 497-line module implementing 12 archetypes, a template generator, quality gate, and LLM refinement hook
  • meta_rules_storage.py — New correction_patterns table with batch upsert and graduation candidate query
  • _core.py — Switched to extract_instruction() as the primary path, with keyword-template fallback when it returns None
  • _context_compile.py — Regex separator pattern refined to (?:\\s*—\\s*|\\s*--\\s*|\\s+-\\s+) (the en-dash drop from the previous review remains unaddressed)
  • test_pipeline_e2e.py — 12 new e2e tests, including cloud-gated @_requires_cloud tests and a pattern-tracking roundtrip test

Confidence Score: 4/5

Safe to merge after fixing the llm_provider docstring mismatch; all runtime paths use the correct .complete() interface today.

The core logic is solid — archetype detection, template generation, quality gate, and the _core.py wiring are all correct. The previously flagged connection leak and hardcoded path are still open but non-blocking. The one new P1 is a docstring documenting the wrong interface method for llm_provider, which causes AttributeError for future custom provider authors — a targeted one-line fix. All 1699 tests pass.

src/gradata/enhancements/behavioral_extractor.py (docstring interface mismatch), src/gradata/_context_compile.py (still missing en-dash in separator regex, missing from future import annotations)

Vulnerabilities

No security concerns identified. The LLM prompt built in _try_llm_extract embeds draft and final text directly, but since this is an internal SDK module and both values come from authenticated user corrections (not external untrusted input), there is no injection risk in the current usage path.

Important Files Changed

Filename Overview
src/gradata/enhancements/behavioral_extractor.py New 497-line module implementing 12-archetype sentence-level extraction; well-structured with from future import annotations and proper logging, but the extract_instruction docstring documents the wrong llm_provider interface method (.extract() vs the actual .complete() call).
src/gradata/enhancements/meta_rules_storage.py Adds correction_patterns table with upsert and graduation candidate query; query_graduation_candidates still leaks SQLite connection on exception (flagged in prior review round, not yet fixed).
src/gradata/_core.py Cleanly wires behavioral_extractor as primary path with keyword-template fallback; variable naming fix (l → lesson) and VALID_SCOPES casing fix are good housekeeping.
src/gradata/_context_compile.py Regex separator updated to named alternation form; en-dash (U+2013) is still missing from the pattern as flagged in the prior review round; also missing from future import annotations (Rule 6).
tests/test_pipeline_e2e.py 12 well-structured e2e tests; hardcoded Windows path fallback for cloud path is still present (flagged in prior review), and the cloud-gated tests gracefully skip on CI.
tests/test_convergence_gate.py Mock target updated from edit_classifier to behavioral_extractor correctly; tests are accurate. Missing from future import annotations (Rule 6).
tests/test_core_behavioral.py Mock target updated correctly; tests cover happy path, None fallback, and exception propagation scenarios.
src/gradata/contrib/patterns/orchestrator.py No functional issues found; clean domain-agnostic routing with proper type annotations and from future import annotations.

Comment:
**Documented `llm_provider` interface doesn't match the implementation**

The docstring declares the expected interface as `llm_provider.extract(draft, final, classification) -> str`, but `_try_llm_extract` at line 435 actually calls `llm_provider.complete(prompt, ...)` — matching the `LLMProvider` abstract base class in `llm_provider.py`. A caller who reads this docstring and implements a custom provider with only `.extract()` will hit `AttributeError: ... object has no attribute 'complete'` at runtime when the LLM hook fires.

The docstring should reflect the actual `.complete()` signature so custom provider authors aren't misled.

📝 Walkthrough

Walkthrough

Adds a deterministic archetype-based behavioral-instruction extractor (with optional LLM fallback), integrates it into brain.correct() as the primary extraction path with a legacy fallback, adds persistent correction-pattern storage/querying, and expands unit and E2E tests covering correction → graduation → meta-rule workflow.

Changes

Cohort / File(s) Summary
Behavioral Extraction Module
src/gradata/enhancements/behavioral_extractor.py
New module implementing a 12-member Archetype enum, ArchetypeMatch dataclass, detect_archetype(), generate_instruction(), and extract_instruction() orchestration with deterministic templates, actionable gating, and optional LLM refinement/fallback.
Core Integration & Minor Naming
src/gradata/_core.py
brain.correct() now calls behavioral_extractor.extract_instruction(...) first for non-converged cases and falls back to legacy extract_behavioral_instruction(...); ensures brain._instruction_cache is initialized when needed; scope validation var renamed (_VALID_SCOPES_valid_scopes) and loop vars in brain_end_session() renamed for clarity without changing control flow.
Persistent Pattern Storage
src/gradata/enhancements/meta_rules_storage.py
Adds PATTERN_SEVERITY_WEIGHTS, creates correction_patterns table via ensure_pattern_table(), implements upsert helpers (upsert_correction_pattern, upsert_correction_patterns_batch) with severity-weight semantics, and query_graduation_candidates() to aggregate/filter patterns by sessions and weighted score.
Tests — Unit & Behavioral
tests/test_convergence_gate.py, tests/test_core_behavioral.py
Updated mocks/patch targets from legacy extractor to behavioral_extractor.extract_instruction; adjusted assertions; added test_correct_persists_legacy_on_extractor_failure ensuring lessons persist when extractor errors.
Tests — End-to-end
tests/test_pipeline_e2e.py
New E2E test module exercising correction → severity derivation → session finalization → lesson graduation → meta-rule discovery → formatting → SQLite persistence, with cloud-gated branches, deduplication, cross-category isolation checks, and pattern-tracking assertions.
Orchestrator minor change
src/gradata/contrib/patterns/orchestrator.py
Switched attribute access to use getattr(brain, "spawn_queue") when selecting parallel execution strategy.
Prospect name parsing tweak
src/gradata/_context_compile.py
Adjusted prospect-name regex to explicitly match separator variants (\s*—\s*, \s*--\s*, \s+-\s+), changing how stems split into prospect/company.

42-44: 🧹 Nitpick | 🔵 Trivial

Consider strengthening the fallback test assertion.

The assertion only checks for presence of state markers (INSTINCT or PATTERN), not whether a specific fallback description was used. Consider also verifying that the lesson description doesn't contain the mocked string (to confirm the fallback path was actually taken).

In `@src/gradata/enhancements/behavioral_extractor.py`:
- Line 314: The parameter `category` on generate_instruction(match:
ArchetypeMatch, category: str = "") is unused—remove the `category` parameter
from the function signature and any default, and then update all call sites that
pass a category (e.g., where generate_instruction(...) is invoked) to call
generate_instruction(match) instead; alternatively, if you intend to vary
templates by category, implement usage inside generate_instruction (e.g., branch
on the category string) and keep the signature—choose one approach and make the
corresponding change consistently across the codebase.
- Around line 416-426: The _try_llm_extract function currently swallows all
exceptions with a bare except; update it to catch Exception as e and log the
exception at debug (or debug + stack) before returning None so failures from
llm_provider.extract are visible; keep the existing flow that returns refined
only if _is_actionable(refined) and otherwise returns None. Target the
_try_llm_extract function and the llm_provider.extract call when adding the
logging; use the module logger (e.g., logger.debug or similar) to record the
exception and any contextual info (draft, final, classification) without
changing return behavior.

In `@src/gradata/enhancements/meta_rules_storage.py`:
- Around line 340-342: PATTERN_SEVERITY_WEIGHTS are aggregation multipliers
(range ~0.5–2.5) used for pattern graduation scoring and are intentionally on a
different scale than self_improvement.SEVERITY_WEIGHTS (which are clamped to
[0,1]); update the nearby comment or docstring in meta_rules_storage.py to
explicitly state that PATTERN_SEVERITY_WEIGHTS are multipliers/aggregation
weights (not per-item severity scores) and mention their numeric range and
relation to self_improvement.SEVERITY_WEIGHTS so future readers won’t expect
clamped [0,1] values.
- Around line 445-465: The SQLite connection opened via sqlite3.connect (conn)
can leak if conn.execute(...).fetchall() raises; wrap the DB usage in a safe
context by either using the connection as a context manager (with
sqlite3.connect(...) as conn:) or surrounding the execute/fetchall with
try/finally and calling conn.close() in finally; update the block that creates
conn, sets conn.row_factory, runs the SELECT (the execute(...).fetchall() call)
and closes conn to ensure conn.close() always runs even on exceptions.
- Around line 345-367: The pattern-tracking helpers (ensure_pattern_table,
upsert_correction_pattern, upsert_correction_patterns_batch,
query_graduation_candidates) are never called so extracted patterns aren’t
persisted; wire them into the correction pipeline by: ensure_pattern_table is
invoked during DB initialization, call extract_patterns from brain.correct() and
immediately persist results using upsert_correction_patterns_batch (or
upsert_correction_pattern for single entries) with the current session_id and
severity metadata, and in brain.end_session() call query_graduation_candidates
to fetch cross-session candidates and incorporate/persist any graduations into
meta-rules (or the existing meta-rule persistence flow); reference these
functions when adding the calls so the persistence happens whenever corrections
are made and at session teardown.

In `@tests/test_pipeline_e2e.py`:
- Around line 90-109: The test assumes discover_meta_rules(...) returns
meta-rules but that function is cloud-gated in the OSS build and may return an
empty list; update the test in test_meta_rule_discovery_from_related_corrections
to handle the gated case by either skipping the test when cloud-gating is active
(use pytest.skip with a clear message) or by asserting conditionally: call
discover_meta_rules(rule_lessons, ...), and if it returns an empty list treat
the test as skipped/expected (or assert len(metas) == 0 with an informative
message), otherwise run the existing assertions on the first meta (referencing
discover_meta_rules, Lesson, and LessonState to locate the relevant code).
- Around line 21-27: Remove the hardcoded Windows path by stopping insertion of
"C:/Users/..." into sys.path; instead only respect an optional
GRADATA_CLOUD_PATH environment variable or prefer the package import fallback.
Update the block that sets _cloud_path (created via os.environ.get) and the
sys.path.insert call so it only inserts when the env var is set and non-empty,
then attempt importing discover_meta_rules and merge_into_meta accordingly
(symbols: _cloud_path, sys.path.insert, discover_meta_rules, merge_into_meta).
Ensure the tests rely on the package import fallback (from
gradata.enhancements.meta_rules) when no env var is provided.

tests/test_pipeline_e2e.py (2)

86-88: Ambiguous variable name l is acceptable in list comprehensions.

The static analysis flags l as ambiguous (E741), but in context (for l in lessons) it's a common and readable pattern for "lesson". No change required, but consider lesson for clarity if refactoring.

Also applies to: 208-216


79-81: Good assertion pattern: checks specific severity values.

The assertion verifies the severity value is one of the expected discrete values rather than just checking truthiness.

src/gradata/enhancements/behavioral_extractor.py (2)

476-478: extract_instruction returns None when category has no fallback.

If the category is not in _GENERIC_FALLBACKS (e.g., "UNKNOWN" or a typo), the function returns None. This is documented in the return type, but callers in _core.py handle this correctly via behavioral_desc or primary.description. Just noting this is intentional.


168-307: Archetype detection logic is comprehensive.

The 12-archetype taxonomy with sentence-level analysis and ordered resolution is well-designed. The confidence values are appropriately in [0.0, 1.0], and the fallback chain (prefix → hedging → constraint → action step → tone → length → reorder → factual → format → content removal → word replacement → fallback) covers the expected correction patterns.

src/gradata/_core.py (1)

228-250: Clean integration of behavioral extractor with proper fallback chain.

The two-stage extraction sequence is well-implemented:

  1. Try archetype-based extract_instruction() first
  2. Fall back to keyword templates via extract_behavioral_instruction() if step 1 returns falsy
  3. Final fallback to primary.description

The isinstance guard on _instruction_cache (line 243) correctly handles uninitialized/None cache. Exception handling preserves the fallback to primary.description.

tests/test_convergence_gate.py (1)

48-55: Mock updated correctly to match new extraction flow.

The patch target now correctly reflects the updated brain_correct() flow where extract_instruction from behavioral_extractor is called first. The non-None return value ensures the primary extraction path is exercised without triggering fallbacks.

tests/test_core_behavioral.py (1)

15-18: Mocks correctly updated to test both extraction paths.

Both tests properly patch the new extract_instruction function:

  1. test_correct_uses_behavioral_description: Returns a string → verifies it appears in lessons
  2. test_correct_falls_back_to_old_description: Returns None → verifies fallback to old description path

This provides good coverage of the two-stage extraction sequence.

Also applies to: 33-36

⚠️ Potential issue | 🟡 Minor

Silent exception swallowing loses diagnostic information.

The bare except Exception: pass hides all errors from LLM extraction, making debugging difficult when the LLM provider misbehaves. At minimum, log at debug level.

Proposed fix

_try_llm_extract function currently swallows all exceptions with a bare except;
update it to catch Exception as e and log the exception at debug (or debug +
stack) before returning None so failures from llm_provider.extract are visible;
keep the existing flow that returns refined only if _is_actionable(refined) and
otherwise returns None. Target the _try_llm_extract function and the
llm_provider.extract call when adding the logging; use the module logger (e.g.,
logger.debug or similar) to record the exception and any contextual info (draft,

Pattern tracking functions are not integrated into the correction pipeline.

These functions (ensure_pattern_table, upsert_correction_pattern, upsert_correction_patterns_batch, query_graduation_candidates) are defined and fully implemented, but are never called from brain.correct() or brain.end_session(). The PR mentions "cross-session pattern tracking," but the architecture shows these helpers are orphaned—corrections don't populate the correction_patterns table. In brain.correct(), extract_patterns() is called but results are not persisted; in brain.end_session(), only meta-rules are discovered and persisted.

Is this intentional (deferred to a future PR), or should these be wired into the pipeline now?

brain.end_session() call query_graduation_candidates to fetch cross-session
candidates and incorporate/persist any graduations into meta-rules (or the
existing meta-rule persistence flow); reference these functions when adding the
calls so the persistence happens whenever corrections are made and at session
teardown.

232-253: ⚠️ Potential issue | 🟠 Major

Preserve the legacy extractor when the new path throws.

Right now the fallback to extract_behavioral_instruction() only happens when extract_instruction() returns a falsy value. If the new extractor raises, Line 251 skips the legacy path and drops straight to primary.description, so a bug in the new code disables the old behavior entirely.

Proposed fix

23-24: ⚠️ Potential issue | 🟠 Major

Remove the developer-specific cloud path from the test module.

Falling back to C:/Users/olive/... makes this suite host-specific and brittle on CI/non-Windows machines. Only prepend GRADATA_CLOUD_PATH when the env var is actually set; otherwise rely on the package import fallback.

As per coding guidelines, "tests/**: Test files. Verify: no hardcoded paths".

Inline comments:
In `@src/gradata/enhancements/behavioral_extractor.py`:
- Around line 416-425: In _try_llm_extract replace the nonexistent
llm_provider.extract call by building a prompt from draft, final, and
classification and invoking llm_provider.complete(prompt, max_tokens=...,
timeout=...) (use appropriate token/timeout values or existing defaults), then
pass the returned text to _is_actionable and return it if actionable; also
remove the silent except and log the caught Exception (include the exception
message and context) so failures to call complete are visible.

In `@src/gradata/enhancements/meta_rules_storage.py`:
- Around line 447-458: The graduation SELECT currently groups by pattern_hash
but selects non-aggregated columns category and representative_text, yielding
arbitrary rows; change the query to explicitly pick a representative row per
pattern_hash (e.g., use a subquery or window function like ROW_NUMBER() OVER
(PARTITION BY pattern_hash ORDER BY created_at DESC) to pick the
latest/highest-weight row) and then join that representative row to the
aggregates (COUNT(DISTINCT session_id), SUM(severity_weight), MIN(created_at),
MAX(created_at), GROUP_CONCAT(...)) so category and representative_text come
from the chosen representative (reference the query built where rows =
conn.execute(...) against correction_patterns).

In `@tests/test_core_behavioral.py`:
- Around line 16-17: The tests currently allow regressions because both
assertions are conditional on lessons_path.exists(); update tests in
tests/test_core_behavioral.py to assert lessons_path.exists() (i.e., that
lessons.md was created) before checking contents, and add a new test case that
patches gradata.enhancements.behavioral_extractor.extract_instruction to raise
an exception (use side_effect=Exception(...)) to simulate the _core.py failure
mode, then run the flow and assert the legacy description (the content written
by the legacy extractor) is persisted into lessons.md; reference the mocked
function name extract_instruction and the file/variable lessons_path/lessons.md
to locate where to add these checks.

In `@tests/test_pipeline_e2e.py`:
- Around line 67-70: The test is forcing every simulated correction to "major"
by using result.get("outcome", "major") when building session_corrections for
end_session(); instead, propagate the real severity from the correction itself
(or fall back to result/outcome if needed). Update the session_corrections
construction in tests/test_pipeline_e2e.py to set "severity" using
correction.get("severity", result.get("outcome", "major")) (or
correction["severity"] if you expect it always present), so the value returned
by brain.correct() and/or the correction entry drives severity-aware graduation
logic in end_session().

232-255: ⚠️ Potential issue | 🟠 Major

Keep the legacy extractor as the fallback when the new extractor throws.

Right now the broad try wraps both branches. If extract_instruction() raises, this code drops straight to primary.description and never calls extract_behavioral_instruction(), so the explicit fallback path disappears on exceptions.

Proposed fix

extract_instruction inside a small try block (catch Exception as e and log the
failure), and if it returns falsy or raises, then proceed to import and call
extract_behavioral_instruction(diff, primary, cache=brain._instruction_cache)

345-486: ⚠️ Potential issue | 🟠 Major

The new correction-pattern pipeline is still not reachable from production flow.

These helpers are implemented here, but the provided src/gradata/_core.py still only counts extract_patterns(...) results and never calls upsert_correction_patterns_batch(...), and brain_end_session() still does not call query_graduation_candidates(). As shipped, correction_patterns never influences graduation.

production flow never persists or uses correction patterns: ensure
extract_patterns results are upserted and graduation queries are invoked by
wiring the new helpers into the core session lifecycle—call
upsert_correction_patterns_batch (or upsert_correction_pattern for single items)
from the code path that currently handles extract_patterns results in
src/gradata/_core.py so patterns are saved per session, and modify
brain_end_session to call query_graduation_candidates (with appropriate
min_sessions/min_score) and feed any returned candidates into the existing
graduation path so correction_patterns influence meta-rule graduation.

Always close the SQLite connection on query errors.

conn.close() only runs after fetchall() succeeds. If the SELECT fails, this connection leaks.

35-35: ⚠️ Potential issue | 🟠 Major

Reintroduce en-dash support in the separator regex.

This pattern dropped (en dash), so stems like Jane Doe – Acme won’t split anymore, which regresses extraction and diverges from src/gradata/_tag_taxonomy.py and src/gradata/_fact_extractor.py.

Proposed fix
-        parts = re.split(r"(?:\s*—\s*|\s*--\s*|\s+-\s+)", stem, maxsplit=1)
+        parts = re.split(r"(?:\s*[—–]\s*|\s*--\s*|\s+-\s+)", stem, maxsplit=1)

317-317: Unused category parameter.

The category parameter is declared but never used in the function body. This was flagged in a previous review.


1-31: LGTM - Module setup and imports.

Proper use of from __future__ import annotations, logging setup, and TYPE_CHECKING guard for the EditClassification import.


64-96: LGTM - Detection vocabulary constants.

The frozensets and compiled regex patterns are well-organized and appropriate for the detection logic.


103-164: LGTM - Sentence-level helper functions.

Clean, pure functions with clear purposes. The _sentence_overlap correctly returns Jaccard index in [0,1], and _to_imperative handles a good variety of prefix patterns.


419-445: LGTM - LLM extraction with proper error handling.

The function now correctly uses llm_provider.complete() with appropriate parameters and logs failures at warning level. The broad exception catch is acceptable here since we want to gracefully handle any LLM provider failure.

tests/test_pipeline_e2e.py (3)

22-28: Hardcoded Windows path still present.

Line 23 contains a hardcoded Windows-specific path C:/Users/olive/SpritesWork/brain/cloud-only. This was flagged in a previous review but remains unchanged. The fallback import works, but the hardcoded path will cause issues in CI/other environments.


45-84: LGTM - Test fixtures and helper function.

SALES_CORRECTIONS provides good test data, and _simulate_session properly extracts severity with a robust fallback chain matching the SDK's return structure.


282-304: LGTM - Pattern tracking test with specific assertions.

Good test coverage for the correction pattern tracking functionality. Assertions check specific values (pattern_hash, distinct_sessions >= 3, weighted_score >= 3.0).

🧹 Nitpick | 🔵 Trivial

Consider adding strict=True to zip() calls for defensive coding.

Lines 198, 242, and 281 use zip() without the strict= parameter. While the lists are constructed together and guaranteed to have the same length, adding strict=True (Python 3.10+) would catch unexpected mismatches during future refactoring.

Example for line 198
-    added_sents = [s for s, ws in zip(final_sents, final_sent_sets)
+    added_sents = [s for s, ws in zip(final_sents, final_sent_sets, strict=True)

⚠️ Potential issue | 🟡 Minor

Docstring/implementation mismatch for llm_provider interface.

The docstring states:

llm_provider: Optional LLM provider for refinement of low-confidence matches.
              Interface: llm_provider.extract(draft, final, classification) -> str

But the implementation in _try_llm_extract (line 435) calls llm_provider.complete(prompt, max_tokens=100, timeout=10). Update the docstring to reflect the actual interface.
