Kunthawat Greethong ead9aeb25c chore: pre-existing in-tree work (event-study/research/vintages/prices + migration script + integrity docs)

Committing the prior uncommitted working-tree state that predates this session's
data-source work (was already modified/untracked at session start) so the tree
is clean before push. Includes: event-study + research report integrity/forward
observation work, prices tests, research hash migration script, and the
2026-08-23/24 engineering-log + test-evidence notes. Verified green as part of
the full 362-test suite.

M2.9 Final Independent Review — 2026-08-24

Status

Review gate: passed for the bounded M2.9 remediation scope under the declared local single-process threat model.
Milestone: complete/blocked — exploratory and forward paper work is available; validated historical PIT research remains blocked.
Commit/push: none performed.

Independent verdict

Reviewer deleg_e5407553 returned the required schema-valid verdict:

{
  "passed": true,
  "security_concerns": [],
  "logic_errors": [],
  "test_gaps": [
    "concurrent read-modify-write persistence and atomic manifest updates",
    "same-raw-payload observation with differing normalized content",
    "invalid, missing, or mismatched predecessor references"
  ],
  "suggestions": [
    "add process-level locking or transactional manifest updates before multi-worker deployment",
    "add malformed-manifest, equal-time, lineage, and predecessor adversarial fixtures",
    "add focused helper and frontend mapping tests"
  ]
}

The security and logic blocker arrays are empty. The listed gaps and suggestions are non-blocking for the current single-process local store and are deferred until the deployment scope expands or focused coverage is prioritized.

Verification basis

Backend: 121 tests passed with -W error.
Backend compileall: passed.
Frontend Vite build: passed.
Production dependency audit: 0 vulnerabilities.
git diff --check: passed.
Static dangerous-pattern scan: no hardcoded-secret assignments, shell execution, eval/exec, pickle, or SQL-f-string matches.
Live smoke: health and observations returned HTTP 200; validated backtest remained HTTP 409 and fail-closed.

Remaining gates

Revised vendor price history remains point_in_time=false.
BOT has only 1/12 independent releases.
No provider has supplied the evidence required by pit-daily-v1.
Do not claim a validated historical backtest or alpha result.
Add locking/transactional persistence before multi-worker or shared-filesystem deployment.

Next action

Continue collecting genuinely independent BOT releases and request a complete PIT provider evidence packet. Keep exploratory output explicitly status=descriptive_only with result_scope=non_pit_descriptive_only.

NEVER include API keys, tokens, passwords, secrets, credentials, or connection strings in the summary — replace any that appear with [REDACTED].
