[P1][audit] Final repository-wide audit for legacy Shugur references

[psam21]

Migrated from docs/pending-work-plan.md §6 + docs/Shugur-Migration-Plan.md Phase 6.

Goal

After the service-reliability fixes (#101–#108) and module-path decision (#109), perform a final audit for legacy references. The audit must classify every remaining Shugur occurrence instead of deleting text blindly.

Reference classification

Reference category	Final treatment
Public product name, page title, service description, README branding	Replace with nostr.ltd branding
Environment variables	Canonical NOSTR_* emitted; legacy fallback retained temporarily
Go module path and imports	Migrate only after #109 decision and clean-clone validation
Historical migration documentation	Retain where useful, clearly label as historical
Copyright, license, attribution, or upstream provenance	Preserve unless legally reviewed
Database/table names and persisted data identifiers	Do not rename casually; document compatibility impact
Backup paths and old systemd units	Keep only if required for rollback; otherwise retire deliberately
Test fixtures and expected strings	Update when they describe current public identity

Audit scope

• Root README
• Copilot instructions (.github/copilot-instructions.md)
• Deployment directory (deploy/)
• NIP tracking documentation (docs/NIP-Tracking.md)
• Test harness (relay/tests/nips/)
• Docker / Compose files
• systemd units
• Package metadata
• Source comments
• Logs (sample, not exhaustive)
• Generated assets

Deliverable

A checklist with file path, line, classification, action, and reviewer status for every remaining Shugur occurrence.

Acceptance criteria

• Every remaining Shugur occurrence is classified.
• Every classified item has an action (replace / retain / preserve / defer).
• Reviewer status recorded for each action.

Dependencies

• Depends on [P1][go] Evaluate Go module-path migration (Shugur-Network/relay → canonical namespace) #109 (module-path decision).
• Blocks [P1][audit] Final repository-wide audit for legacy Shugur references #110 (alias removal, if approved).

Dependency map:

• Blocked by [P1][go] Evaluate Go module-path migration (Shugur-Network/relay → canonical namespace) #109 (module-path decision must be made first).
• Blocks [P2][cleanup] Remove SHUGUR_* legacy aliases after production migration gate #111 (alias removal depends on the audit).
• Tracked by [open][migration] Phase 6: deprecation and removal of legacy aliases #119 (Shugur migration Phase 6).
