-# \_Uncertain Reclassification Workflow Guide
-Generated on: 2026-02-23 04:00:02
-------------------------------------------------------------------------
-## Overview
-This document describes a safe and extensible workflow for reclassifying
-files from the `_Uncertain` folder **without modifying original SHA-256
-hashes**.
-Core principles:
--   SHA-256 original file list remains untouched
--   Files are never edited (no EXIF rewrite, no re-save)
--   Reclassification is handled via external override records
--   Design
-ed to support future expansion (albums, people, places)
-------------------------------------------------------------------------
-# Step 0 -- Create Operational Folders
-Create:
-PhotoVault\
-  _ops\
-  _ops\reclass\
-  _ops\notes\
-_ops`\reclass`{=tex}\
-PhotoVault_ops`\notes`{=tex}\
-These folders store operational metadata only.
-------------------------------------------------------------------------
-# Step 1 -- Export \_Uncertain List
-``` powershell
-$unc = "PhotoVault\Media\_Uncertain"
-Get-ChildItem $unc -File -Recurse |
-Select-Object FullName, Name, Length, LastWriteTime |
-Export-Csv "PhotoVault\_ops\reclass\uncertain_review.csv" -NoTypeInformation -Encoding UTF8
-```
-------------------------------------------------------------------------
-# Step 2 -- Manual Review
-Open `uncertain_review.csv` in Excel.
-Add two columns:
--   year_final
--   note
-Fill only confident cases.
-Save as:
-PhotoVault_ops`\reclass`{=tex}`\uncertain`{=tex}\_review_done.csv
-------------------------------------------------------------------------
-# Step 3 -- Create Year Override File
-``` powershell
-$in  = "PhotoVault\_ops\reclass\uncertain_review_done.csv"
-$out = "PhotoVault\_ops\reclass\year_override.tsv"
-Import-Csv $in | Where-Object { $_.year_final -match '^\d{4}$' } |
-ForEach-Object {
-    $h = (Get-FileHash $_.FullName -Algorithm SHA256).Hash
-    "{0}`t{1}`t{2}`t{3}" -f $h, $_.year_final, (Get-Date -Format "yyyy-MM-dd"), ($_.note -replace "`t"," ")
-} | Set-Content $out -Encoding UTF8
-```
-Format:
-sha256`<TAB>`{=html}year_final`<TAB>`{=html}date`<TAB>`{=html}note
-------------------------------------------------------------------------
-# Step 4 -- Move Files to Year Folder
-``` powershell
-$in  = "PhotoVault\_ops\reclass\uncertain_review_done.csv"
-$rootMedia = "PhotoVault\Media"
-$log = "PhotoVault\_ops\reclass\move_log.tsv"
-Import-Csv $in | Where-Object { $_.year_final -match '^\d{4}$' } |
-ForEach-Object {
-    $src = $_.FullName
-    $yy  = $_.year_final
-    $dstDir = Join-Path $rootMedia $yy
-    if (!(Test-Path $dstDir)) { New-Item -ItemType Directory -Path $dstDir | Out-Null }
-    $dst = Join-Path $dstDir $_.Name
-    if (Test-Path $dst) {
-        $h8 = (Get-FileHash $src -Algorithm SHA256).Hash.Substring(0,8)
-        $dst = Join-Path $dstDir ("{0}_{1}" -f $h8, $_.Name)
-    }
-    Move-Item -LiteralPath $src -Destination $dst
-    "{0}`t{1}`t{2}`t{3}" -f (Get-Date -Format "yyyy-MM-dd HH:mm:ss"), $src, $dst, "moved" |
-      Add-Content $log -Encoding UTF8
-}
-```
-------------------------------------------------------------------------
-# Optional -- Future Annotation File
-Create:
-PhotoVault_ops`\notes`{=tex}`\annotations`{=tex}.tsv
-Format:
-sha256`<TAB>`{=html}key`<TAB>`{=html}value`<TAB>`{=html}date
-Example:
-AAA... place Jeju Seongsan 2026-02-23 AAA... people Mom;Dad 2026-02-23
-This allows future expansion to albums, people, places without changing
-the core index.
-------------------------------------------------------------------------
-# Operating Loop
-.  Review `_Uncertain`
-.  Fill `year_final`
-.  Generate `year_override.tsv`
-.  Move files
-.  Repeat until `_Uncertain` shrinks
-------------------------------------------------------------------------
-# Design Philosophy
--   Files are immutable objects
--   SHA-256 is permanent identity
--   Reclassification is metadata
--   Albums and annotations are relationship layers
