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
• Designed to support future expansion (albums, people, places)

Create:

PhotoVault_ops
PhotoVault_ops\reclass{=tex}
PhotoVault_ops\notes{=tex}\

These folders store operational metadata only.

$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

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

$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

$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
}

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.

1. Review _Uncertain
2. Fill year_final
3. Generate year_override.tsv
4. Move files
5. Repeat until _Uncertain shrinks

• Files are immutable objects
• SHA-256 is permanent identity
• Reclassification is metadata
• Albums and annotations are relationship layers
