Admin panel — Reset all data & Delete user

Backend Frontend

Reset all data button — new amber header button wipes all 23 user-data tables (trades, runs, evidence, memory, snapshots, persona, progress) while keeping user accounts. Previous "Clear all trades" only covered 10 tables.
Delete user button (per row) — permanently removes a user account and every associated row across 19 tables including email_users. Two-step confirmation required.
Refactored delete logic — shared _delete_user_rows() helper ensures both Clear data and Delete user cover the same comprehensive table list.
New endpoints — DELETE /api/v1/admin/reset-all-data and DELETE /api/v1/admin/users/{email}.

Cost removed from Critical gating + MT4/MT5 auto-analysis trigger

Backend Fix Tests

Cost is now evidence, not a gate — apply_cost_gate() no longer demotes statistically-eligible Critical candidates to Watchlist. Dollar cost is shown as context alongside the pattern. Previously zero patterns reached Critical in production because XAUUSD small-account losses sat below the $20 threshold.
cost_context field — candidates now carry cost_context ("costly" or "not_costly_in_sample") and cost_gate_suppressed: false so reports can frame cost evidence appropriately without blocking the finding.
MT4/MT5 auto-analysis trigger — after a terminal sync saves trades, the backend now checks: ≥ 5 pending trades AND ≥ 6 h since last run → fires analysis automatically in the background. New analysis_status values: analysis_triggered, analysis_pending_threshold, analysis_pending_cooldown, analysis_trigger_failed.
Root markdown cleanup — all 28 root-level planning docs reviewed, annotated, renamed with _reviewed_may26_2026 suffix, and archived to docs/ or PRODUCT/.
470 tests passing after all changes.

Chart embed replay — daily report & full report

Frontend Backend Tests

Daily report replay card — now shows an inline /embed/replay chart for every run, including older uploads where the backend embed URL wasn't previously verified. Fallback chain: backend iframe → client-built /embed/replay → /embed/chart.
Full report — new Pivotal Moment section — renderBehaviorReplay() added to the critical, systematic, and default render paths. Shows the selected moment with 16:9 inline iframe, narration beats, comparison flash, and a direct chart button.
Chart base URL — CHART_EMBED_BASE_URL updated from localhost:8001 to https://1candletrader.com in .env and .env.local. Backend now builds live chart URLs for new uploads.
Frontend contract tests — 55-test file (tests/test_template_frontend_contract.py) covers chart URL safety, JS function presence, embed URL patterns, modal IDs, button wiring, and replay fallback logic for both pages. Registered in --suite ui.

Documentation sync + test coverage for recent modules

Docs Tests Fix

CLAUDE.md / AGENTS.md rewritten — shorter, innovation-friendly, distinct roles (dev reference vs product guide).
cross_session_analysis.py bug fix — dominant_pattern() queried non-existent fpc.title column; replaced with json_extract(fpc.candidate_json, '$.title').
New test files — test_eng__pipeline__costly_watchlist.py (costly-watchlist selector regression guard), test_eng__cross_session_analysis.py (DB-integrated), test_pydantic_v2_schema.py (schema import smoke tests).
Existing tests extended — test_eng__primary_case__contract.py adds watchlist_preview + missed_continuation cases; test_eng__report_payload__contract.py adds receipt price-field assertions.
test_comparison_stage.py registered — was silently excluded from the test runner; now included in --suite engineering.
TEST_COVERAGE_BY_STAGE.md — 5 new rows, 2 updated, 3 gaps closed, 2 new gaps documented.
full_upload_pipeline.md — Returning-User Path section added documenting comparison_stage.py and cross_session_analysis.py.

Backend stage quality pass

Backend Tests

Primary focus evidence refresh — rebuilt after comparison/routing context exists so copy distinguishes first baseline from returning comparison and current upload vs account-memory scope.
report_claims_v1 — centralises hero claim, proof summary, costs, comparison state, and evidence actions. Full report prefers this contract with fallback to older fields.
Behavior memory snapshot persistence — additive write; used by later uploads to classify comparable reports and build transformation/returning-report states.
May 24 hardening — MARKET_DATA_DIR env propagation, env-key tests, daily blank screen fix, chart modal z-index fix, replay chart status tests.

Full report proof flow + report service extraction

Backend Frontend

full_report_service.py — extracted report resolution and rebuild path from the router into a dedicated service module.
primary_focus_evidence contract — implemented and attached inside reveal and v4_report. Full report hero prefers this over scattered reveal fields.
Report hero rewrite — full report prefers report_claims_v1 and backend claim/proof fields; older fields remain as fallback.
Comparison stage + cross-session analysis — comparison_stage.py builds period-over-period deltas for returning users; cross_session_analysis.py supplies dominant_pattern() and losing_day_frequency() to comparison router.
Habit frequency card + losing streak detector — _PATTERN_CONFIG modularised; losing streak detection added.

Upload & report UI — partials, chart embeds, MT5 assets

Frontend

Upload partials — upload_modal.html and upload_home.html extracted as reusable partials served via /upload-modal and /upload-home routes.
Inline evidence strips — trade receipt strips with Chart buttons added to daily report story cards and proof panel.
Pydantic v2 migration — six schema files migrated to Pydantic v2 ConfigDict / Field wrapper pattern.
MT4/MT5 logo assets — plugin tile UI added to upload screen.
Pattern evidence report — compact card design, undetected patterns toggle, upload trigger in header.

Trade traceability — DB helper, candidate trades API, report element IDs

Backend Frontend Tests

Candidate trades API — GET /runs/{run_id}/candidates/{candidate_id}/trades returns affected and counterexample trade lists for any analysis run.
Report element candidate_id — elements now carry candidate_id and trade_count so the frontend can load trades on demand.
Upload UI in full report — drag-and-drop upload modal added to report.html for in-report re-upload.
Trade traceability tests — scripts/test_trade_traceability.py covers DB helper, API endpoint, and report element contract.

Pattern evidence report — undetected patterns, chart modal

Frontend Docs

Pattern evidence report — single-page archive report at /pattern-evidence-report showing all detected and undetected patterns with evidence receipts.
Undetected patterns panel — lists all known patterns that were checked but didn't qualify for the current upload.
Chart modal — chart URL registration and iframe modal added to pattern evidence, focus reveal, and full report pages.
patterns.json — static reference dataset added; consumed by the pattern evidence page.

Skill map coverage audit + behavioral metrics plan

Backend Tests

43 test suites passing — all phase scripts green after behavior metrics pass.
Detectors verified — max daily loss compliance, breakeven stop, drawdown behavior, win streak overconfidence, and lot escalation detectors confirmed present and covered.
Performance statistics card — report_elements.py builds performance_stats as supporting evidence in the v4 report.
