+# Evidence assets manifest
+
+This directory holds the curated evidence captures referenced by the SAM
+website. Every image here is a real screenshot of SAM software. Nothing is
+mocked up, AI-generated or edited beyond cropping.
+
+## Manifest
+
+Every file listed is committed in this directory and wired into the page.
+
+| ID | Filename | Website location | Caption (as published) | Priority |
+|---|---|---|---|---|
+| E01 | `E01_SAM_PartF_Design_Airflow_Overlay.png` | Hero; social preview image | The SAM analytical model in the SAM Analytical desktop app: engineering data reviewed directly on the model, here ventilation requirements beside design airflows. (Legend: F = Part F requirement, D = design airflow.) | Primary |
+| E01 (detail) | `E01_SAM_PartF_Design_Airflow_Overlay_Detail.png` | Workflow step 01 | Bedroom supply: Part F requires 63 l/s; the design holds 143 l/s. Two quantities on one plan. | Primary |
+| E02 | `E02_SAM_PartO_Review_Iteration_Authority.png` | Workflow step 02 | The regulatory requirement, engineering design and selected equipment capacity remain separate decisions. | Primary |
+| E03 | `E03_SAM_PartO_Prepare_Run_Status.png` | Workflow step 03 | SAM materialises the engineering design into a deterministic simulation scenario and records the run state. | Primary |
+| E04 | `E04_SAM_PartO_TM59_Result.png` | Workflow step 04 | Example TM59 assessment showing the recorded room-level outcome; SAM reports the result rather than forcing a pass. | Primary |
+
+## Provenance of E01–E04 (captured 2026-09-16)
+
+All four were captured in one continuous session on 2026-09-16, from the real
+`SAM Analytical.exe` desktop app driven through its own UI (the same UI
+Automation route as the SAM#111 Part O acceptance harness). Nothing was
+simulated, typed into a result or edited outside the application.
+
+| Item | Value |
+|---|---|
+| Build | Release, `/t:Rebuild`, 0 errors, 2026-09-16 22:41, from `sow/2026-Q3` tips: SAM `e2c0e2c0`, SAM_Systems `05ca0c18`, SAM_Tas `c267f52f`, SAM_UI `9f515c4c` |
+| Simulation engine | EDSL Tas 9.5.7 (licensed), full year, days 1–365 |
+| Model | Three-dwelling residential model (Flat 1 / 2 / 3 + corridor, 8 assessed rooms): a fresh copy of the model used for the SAM#111 real-project acceptance (source SHA-256 `a7e09a25…`). Model name `000000_SAM_AnalyticalModel-It1a-futureZ1`; no client, address or project identifiers. |
+| Weather | The model's own CIBSE DSY 2050s design weather (`Z1_DSY1_2050s_HIGH90`) |
+| Route | Simulate → Part O Prepare & Run → Iteration 2 (automatic catalogue selection) → Tas → TM59 → Optimise (Iteration 2B, 5 l/s step, limit 10) |
+| Outcome | TM59 **FAIL** after Iteration 2 (6 of 8 rooms) and after the last valid 2B round, run 10 (6 of 8 rooms). Room figures reproduce the SAM#111 acceptance record exactly. |
+
+| File | Pixels | Screen | What it shows |
+|---|---|---|---|
+| E01 | 1604 × 568 | Main window, plan view `Level 0`, *Part F Airflow* overlay (annotation scale 1:150) + *Ventilation Design* overlay, after 2B | Flat 1 and Flat 2: F tags = Approved Document F requirement, D tags = design airflow held by the model (e.g. bedroom supply F 63 / D 143 l/s). Transfer tags carry SAM's own "?" status (no modelled transfer opening identified). |
+| E01 detail | 1095 × 532 | Same view, zoomed on Flat 2 | Bedroom, kitchen and ensuite tags at legible size |
+| E02 | 1116 × 368 | *Part O — Iteration 2B — TM59 optimisation* window, grids scrolled to run 10 | Design airflow history (design before / requested / achieved / Part F required / TM59) and serving-unit history (duty 143/143 vs max 150/150, headroom 7/7, product kept) |
+| E03 | 1345 × 904 | Main window plan + *Part O — Prepare & Run* hub, Iteration 2 selected, after the run | Scenario, automatic catalogue selection, Max as capability ceiling, configuration status and Simulation / Results READY |
+| E04 | 1345 × 730 | Main window plan + *Part O — Overheating (TM59)* window for run 10, report scrolled to the verdict | TM59 occupied-space assessment FAIL and the per-room mechanical-ventilation table |
+
+Preparation: crop only, from window captures (`PrintWindow`) or a 1920 × 1080
+screen frame with no scaling, annotation or retouching. Crops remove the
+Windows title bar and taskbar, and in E04 the window's summary line, which
+held a local output path. E03 and E04 are single real screen states (a dialog
+over the main window), not composites. The Review-iteration notes panel and
+the 2B notes panel, which list local paths, are outside the crops.
+Source frames were 1920 × 1080 at 100 % Windows scaling, so the E01–E04
+widths are native pixels and have not been upscaled.
+
+## Rules
+
+- Captures are real screenshots of capability merged on the `sow/2026-Q3`
+  release line, taken from a Release build of that line.
+- Allowed preparation: crop, scale, and captions/annotation *outside* the
+  software image. A composite of two legitimate views must be labelled as one.
+- Part O Iterations 1a / 1b / 2 / 2B (frozen 2026-09-08) may be shown as
+  validated capability. Do not show an Iteration 2 acoustic-restriction, bypass
+  or boost result: those behaviours are not implemented.
+- Part O Iteration 3 may be shown as validated capability only for what the
+  [SAM#111](https://github.com/SAM-BIM/SAM/issues/111) final closeout
+  (2026-09-16) accepts: the explicit Systems/TPD ventilation route and the
+  selected-product cooling mode. Never show manufacturer heat-recovery, fan
+  or bypass behaviour: that work is tracked separately in
+  [SAM#123](https://github.com/SAM-BIM/SAM/issues/123) and is not accepted.
+- Never caption a failing TM59 run as a pass.
+- The homepage presents SAM as a platform; Part F / Part O is its flagship
+  example. Keep programme detail (tracker state, open technical questions,
+  evidence gates) in the linked GitHub records, not in homepage copy.
+- No client or project-identifying data, personal or employer file paths,
+  usernames, taskbars or other desktop chrome in frame.
+- PNG source captures; keep them legible at ~1100 px rendered width.
+- Do not commit dummy or AI-generated imagery.
