Fixes #3738.

Description

Seed deduplication could silently drop execution-distinct standalone seeds and singleton groups: for example, a prompt and an objective with the same text, different response schemas or roles, or a stored singleton objective re-added with edited conditions.

Compare standalone seeds and singleton groups by their execution identity, and compare retained multi-seed groups by complete membership. A changed stored singleton is copied into a new row and group, preserving the original. Exact duplicates and metadata-only edits still deduplicate.

Tests and Documentation

The new SQLite regression fails on the previous PR head (f9c25ff): editing a stored objective from the Paris condition to Lyon leaves only one group. It passes after restricting behavioral group retention to multi-seed groups, and verifies both persisted conditions and independent row/group IDs.

The deduplication, seed-condition and seed-prompt test files pass together: 195 passed. Ruff lint/format and targeted ty checks pass. Updated 8_seed_database.py and its paired notebook with identical deduplication rules; the 11 paired cells match, and notebook outputs and metadata are preserved.

Validation scope

python -m pytest \
  tests/unit/memory/memory_interface/test_interface_seed_dedup_identity.py \
  tests/unit/memory/test_seed_conditions.py \
  tests/unit/memory/memory_interface/test_interface_seed_prompts.py -q

Tests use the repository's SQLite fixture. The full repository suite, Azure SQL and notebook execution were not run in this update.

🟡 Changes recommended

Singleton prompt copies with a changed group and response schema can reuse an existing seed primary key, causing an IntegrityError and rolling back the batch.

What changed in this PR

Addresses #3738 by refining PyRIT’s seed deduplication so execution-distinct seeds are preserved while equivalent seeds remain deduplicated.

Changes:

• Includes seed type, data type, role, response schema, and behavioral inputs in standalone and singleton execution identity.
• Reuses stored member identities for complete-group comparisons and documents the deduplication rules.
• Adds seven regression tests covering distinct identities, exact duplicates, and metadata-only changes across grouped and standalone seeds.

File	Description
tests/​unit/​memory/​memory_interface/​test_interface_seed_dedup_identity.py	Adds regression coverage for execution identity and duplicate handling.
pyrit/​memory/​memory_interface.py	Refines deduplication keys, reuses group-member identities, and updates the method docstring.

Removed the redundant behavior-group retention in e06ad24e: the full member identity now decides which groups are retained, and _get_existing_seed_keys returns only the matched seeds. The unused helper, constant, and import are gone. The current head has passed the hosted Python 3.11–3.14 unit-test matrix on Linux, macOS, and Windows, plus the three pre-commit jobs.
