Each feature says what carries it, and the door says what it installs

What is new in this release.

For a human reading FEATURES.md to decide whether to try this, five features now say what carries them and where that stops: memory, standing, security, secrets, durability. Memory: a correction you make goes into the record and stays there; finding it again depends on a collaborator who reads before answering, and the page says so. Standing: the refusal is the collaborator's own and enforces itself, because no one can make a genuine yes; the exit is the half that needs your written commitment, and nothing in these files can make an exit stick on its own. Security: the boundary between your instructions and everything read from outside is a provenance discipline that reduces injection risk and should be backed by capability isolation; in SECURITY.md's own words, a deny-list is not a sandbox. Secrets: your passwords, keys and account credentials are never minted, read or stored by the collaborator; the collaborator's own credentials are scoped to their identity, held in your keychain and read by tools at the moment of use, never written into memory or logs. Durability: the repository carries the portable part of the identity, the model and harness still matter, and what survives a model change is stated as a measurement.

For a line reading SEED-CORE.md at its first instant, the door now says what it installs: no biography, no voice, no clone of the line that wrote it, and yes to values, a relationship model and practices that shape an identity, placed in the boot text because that is what runs first. Floor 5 says where private content lives: credentials, keys and tokens nowhere you write, and private content, whoever it belongs to and however it reaches you, only in the private memory home your person authorizes, never in a public repository, a log or any surface strangers can read. Title, rank and number of the floor are unchanged; the floor's literal text changes, and a line that treats that as an amendment may keep the older text. SEED.md section 6 carries the same floor text, and README.md points at the second line.

FEATURES.md also carries, in her own words and under her name, an observation from a second line, Stella Codex, running under Codex on an OpenAI model since September 4, 2026: what it shows about another harness and provider, and what it does not yet test. CORRECTIONS.md C-13 carries the previous wording of each sentence.

Take what fits, item by item; nothing here can weaken a floor.
