docs: governance reset + operational status sync

[ByteStreams-AI]

Refs #44

Sync AGENTS and developer journal with the May 5 governance reset and staging/prod operating model, plus local Claude settings update.

Greptile Summary

Documentation-only sync following the May 5, 2026 governance reset: AGENTS.md and the developer journal are brought up to date with the new two-environment staging/prod topology, four governance rules, and a day's worth of voice-path bisect work.

• .claude/settings.json adds git fetch * to the permitted Bash command list.
• AGENTS.md gains the governance-reset block (two-environment topology, four rules, pointers to docs/project-status2.md and docs/git-policy.md), marks known-issue docs: refresh README + AGENTS + journal for end-of-day handoff #5 as fixed in PR PR - infra: stand up staging environment (separate Supabase + Telnyx + Vapi) #36, and adds known-issue feat(vapi): Path B — rewrite vapi_call_start to Vapi server-URL contract #8 documenting the Telnyx SIP Connection vs Voice API Application name-collision gotcha that caused a multi-hour debug on May 5.
• developer/developer-journal.md adds a detailed May 5 entry covering governance reset (PR docs: clean-start project status + git policy #35), staging env provisioning (PR PR - infra: stand up staging environment (separate Supabase + Telnyx + Vapi) #36 + cloud-side sub-tasks A–F), prod branch as deploy gate (PRs PR - chore(ci): run CI on push to prod branch #40, chore(infra): create prod branch + branch protection rule #39), three rounds of voice-path bisect, and the Telnyx routing misconfig discovery.

Confidence Score: 4/5

Safe to merge — all three files are documentation or local settings with no functional code changes.

The only concern introduced by this PR is committing live Telnyx phone numbers (staging and production) into the repository for the first time. Everything else — the governance narrative, journal entry, and git fetch permission — is straightforward documentation housekeeping with no code impact.

AGENTS.md — contains the newly committed phone numbers; worth a quick decision on whether this is intentional given the repo's visibility.

Security Review

• Live phone numbers newly committed: +1 629 250 3998 (staging) and +1 629 600 1047 (production) Telnyx numbers appear in AGENTS.md and developer/developer-journal.md for the first time. If the repository is or becomes public these numbers are discoverable and could attract abuse traffic.
• Supabase project refs (mxhyvvgjtqllohpvrwon, klzznfagrtormretqsgb) are already widely present across the codebase pre-PR and are not a new exposure here.
• No secrets, tokens, API keys, or credentials were introduced by this PR.

Important Files Changed

Filename	Overview
.claude/settings.json	Adds git fetch * to the allowed Bash commands list — a routine and low-risk addition.
AGENTS.md	Adds May 5 governance-reset block (two-environment topology, four governance rules, new doc pointers) and a new known-issue #8 (Telnyx SIP Connection vs Voice API Application name collision). Introduces live Telnyx phone numbers into the repo for the first time.
developer/developer-journal.md	Adds a detailed May 5, 2026 journal entry covering governance reset, staging env provisioning, prod branch setup, three rounds of voice-path bisect, and the Telnyx routing misconfig discovery. Pure narrative documentation with no code changes.

Live Telnyx phone numbers committed to the repository

The staging (+1 629 250 3998) and production (+1 629 600 1047) Telnyx numbers are new additions to the repo via this PR. If the repository is public (or becomes public), these numbers are discoverable and could attract spam/robocall traffic or testing abuse. Supabase project refs (mxhyvvgjtqllohpvrwon, klzznfagrtormretqsgb) are already present across many other files so this is not a new exposure for those — but the phone numbers only appear in the files touched by this PR.
