proof(SafeGit): DISCHARGE forbiddenRefCharsAnchor via Refl (proven#90) - #102
Merged

Conversation
`forbiddenRefChars` is `public export` in SafeGit.idr L24-26 with this exact list literal as its body. The elaborator unfolds the LHS to the RHS for `Refl`. No "Char-list reduction" is needed — both sides are the same literal after `public export` unfolding. One-line proof: - forbiddenRefCharsAnchor = Refl Conversion: - `0 forbiddenRefCharsAnchor : ...` (type-only OWED) → `public export forbiddenRefCharsAnchor : ... = Refl` Same "OWED comment was overly cautious" pattern as the prior 7 discharges this session (#97, #98, #99, #100, #101). The other 2 SafeGit OWEDs (emptyRefNameInvalid, refNameExtracts) DO have real String-FFI / auto-implicit blockers per their OWED comments and are out of scope.

…clear) All 5 OWEDs in this file share the SafeCron / SafeGit "definitional anchor" pattern (PR #101, PR #102): they're definitional anchors on public-export smart constructors or record-update functions. All discharge by Refl. Discharged: - makeNonDelegatableSetsFalse — record-update projection on `{ capDelegatable := False }` - setExpirySetsJust — record-update projection on `{ capExpiry := Just t }` - emptyStoreNoCapabilities — record projection on named constructor - emptyStoreNoRevoked — record projection on named constructor - adminHierarchyDef — definitional equality All 5 OWED comments cited "public export body opacity" as the blocker — inverted diagnosis (public export ENABLES type-level unfolding). This is the seventh PR in today's overly-cautious-OWED hunt (addParamIncreasesCount, anyMatchesNonNewline, negateInverts/unionIsOr, validResultIsValid, 9 SafeCron anchors, forbiddenRefCharsAnchor, now 5 SafeCapability anchors).

Yet another "OWED comment was overly cautious" discharge in the proven#90 Phase 3 campaign.
What it does
```idris
public export
forbiddenRefCharsAnchor :
forbiddenRefChars = [' ', '~', '^', ':', '?', '*', '[', '\\', '\x7F']
forbiddenRefCharsAnchor = Refl
```
Why it works
`forbiddenRefChars` is `public export` in SafeGit.idr L24-26 with this exact list literal as its body. The elaborator unfolds the LHS to the RHS for `Refl`. No "Char-list reduction" is needed — both sides are the same literal after the standard `public export` unfolding.
Out of scope
The other 2 SafeGit OWEDs have real blockers:
