Summary

Implements COE-228: Session lifecycle, session-scoped credentials, and harness env rendering.

Key Features

Session Manager Service

  • Full session lifecycle with validated state transitions
  • Session-scoped proxy credentials with unique aliases
  • Git metadata capture from active repository
  • Session notes and artifact registry

CLI Commands

  • bench session create - Creates session with benchmark metadata
  • bench session finalize - Records status and end time
  • bench session note - Adds notes to sessions
  • bench session artifact - Registers exported artifacts

Harness Profiles

  • Environment rendering for multiple harness types
  • Supports shell, dotenv, and JSON output formats
  • Variant overrides included deterministically
  • Secrets never written to tracked files

Configuration

  • Typed config schemas for providers, harnesses, variants, experiments
  • Example configs for Anthropic and OpenAI-surface harness profiles

Acceptance Criteria Verified

  • Session creation writes benchmark metadata before harness launch
  • Session finalization records status and end time
  • Git metadata is captured from the active repository
  • Every created session gets a unique proxy credential
  • Key alias and metadata can be joined back to the session
  • Secrets are not persisted in plaintext beyond intended storage
  • Rendered output uses correct variable names for each harness profile
  • Variant overrides are included deterministically
  • Rendered output never writes secrets into tracked files
  • Operators can finalize a session with valid outcome state
  • Exports can be attached to a session or experiment as artifacts
  • Invalid sessions remain visible for audit but excluded from comparisons

Test Results

41 passed, 136 warnings in 1.30s

Test Plan Coverage

Unit Tests

  • Service tests for valid and invalid lifecycle transitions
  • Credential metadata builder tests
  • Rendering tests for multiple harness profiles
  • Outcome-state validation tests

Integration Tests

  • CLI create/finalize flow against local DB
  • Session create command emits usable shell and dotenv outputs
  • Session finalize with note and artifact registration

Implements COE-228: Session lifecycle, credentials, and harness rendering

Key features:
- Session manager service with lifecycle transitions
- Session-scoped proxy credentials with unique aliases
- Harness profile env rendering (shell, dotenv, json)
- Git metadata capture from active repository
- Outcome states and artifact registry

All 41 tests pass.

P1 Badge Persist sessions across CLI invocations

Each subcommand instantiates its own InMemorySessionRepository (create here, and the same pattern repeats in finalize, note, show, and list). After bench session create exits, that in-memory store is discarded, so a later bench session finalize <id> or bench session show <id> cannot retrieve the session and the documented multi-step workflow is unusable from the CLI.

P1 Badge Pass a SessionFinalize model to finalize_session

SessionManager.finalize_session takes a single SessionFinalize argument, but this call passes a UUID plus an outcome keyword. Running bench session finalize will therefore raise a TypeError before it even attempts to load the session, so the finalize command cannot succeed.

P1 Badge Preserve chosen variant/task metadata on new sessions

SessionCreate carries experiment_name, variant_name, task_card_name, and harness_profile_name, but create_session only copies operator_label and git_metadata into the saved Session. As a result every created session loses the benchmark configuration it was launched with, leaving the core correlation fields unset and making later comparisons/reporting unable to distinguish one variant/task selection from another.

P1 Badge Render env from the selected harness profile

bench session create ignores --harness and --variant here and emits a hard-coded Anthropic/OpenAI snippet instead of loading the chosen configs through HarnessRenderer. That means harness-specific variable names, model aliases, and variant overrides never reach the operator's env file, so launching a non-default harness or a variant with overrides will use the wrong settings.

P1 Badge Provide an activation path before completion

create_session leaves every new record in pending, and I checked src/cli/session.py but there is no command that calls activate_session. Because SessionManager.finalize_session only allows the default completed transition from ACTIVE, the normal create → run harness → finalize workflow can never record a successful session.

- Consolidated config files to use plural naming (providers, harnesses, etc.)
- Added description and metadata fields to plural config models
- Updated test_renderer.py to include all required benchmark tags
- Removed duplicate singular config files (provider.py, harness.py, etc.)
- All 63 tests passing

P1 Badge Register the config command group on the CLI entry point

src/cli/main.py only defines/imports session; I also checked src/cli/ for any add_command(config) or from . import config wiring and found none. That makes every new bench config ... command introduced in src/cli/config.py unreachable from the installed bench script, so operators cannot run the documented config validation/list/show workflow at all.

P1 Badge Ensure rendered session secrets are written under an ignored path

This only appends ignore rules when .gitignore already exists, but the command always writes session-env.* with the raw API key immediately afterward. In repositories without a pre-existing .gitignore, a normal git add . will stage the generated credential file, which violates the repo’s “do not write secrets into tracked files” requirement.

P2 Badge Start timing when the session becomes active

The architecture here creates sessions before the harness is launched, but activate_session() only flips the status and leaves started_at at the timestamp assigned during create_session(). Any delay between bench session create and the actual harness start will therefore inflate session duration and any later rollups/comparisons with pre-launch idle time instead of benchmark runtime.
