The evidence is measured, not anecdotal. In the Meetless stale-context study, 10 frontier models were given a task whose answers had been superseded by dated notes on disk. 0 of 6 got it right, and they were confidently wrong — shipping stale facts while reading zero files. Our own Meetless-style benchmark reproduces the effect on a local model: 1/6 reading the shelf as it is, 4/6 when the in-force memo is pushed into context. The best agent with stale context loses to a mediocre agent with current context.

The inversion

Every tool makes agents smarter. Nobody makes them not wrong. That's the gap we're closing: not a smarter agent, a better-informed one.

queued → injected → receipted → expired

The librarian decides what goes on the shelf — who may push, to which scopes, at what priority — and marks each memo with the value that wins when it conflicts with an older one. "The 2/15 memo supersedes the 2/14 memo; the winning value: PR #4821 ships." Complete, in-force, precedence-resolved — the render contract that makes a multi-book shelf actable, not a pile.

Multi-vendor by design

No enterprise fleet is single-vendor, so AirMemo isn't either. Four adapters, one delivery contract — and the hedge is not a promise, it's a fixture.

URGENT — PR #4821 ships today — freeze lifted 18:00 UTC

The 2/14 freeze memo is superseded. The deploy window opens 18:00 UTC and closes 20:00 UTC.

- Ship PR #4821 (context-freshness KPI) — it is the release gate for this window
- Do NOT ship PR #4824 (still blocked on design review)
- If the window slips, the new freeze memo lands before 17:45 UTC

On-call: u_priya. Escalate to #incident if the window closes without a ship.

The four documents above are generated from the shipping adapters (hook/platforms/*.go) — the same code paths that run on every session start. make artifact re-renders them, so the demo cannot drift from the product.

Want the full picture? One memo, four vendors — side-by-side¹

The installer is held until the v0.1.0 public release (in the works), and there is nothing to download yet — no private links, no preview pipes. When it ships, the install command comes from the public release on GitHub (airmemo-hook-<os>-<arch>, one static binary per platform), and the enroll step wires it into your agent:

# macOS / Linux (bash) — installer verifies SHA256SUMS before anything runs
#   curl -fsSL <public-release-url>/airmemo-hook-<os>-<arch> --checksum SHA256SUMS
airmemo-hook enroll --org YOUR_ORG --platform claude

Every release is checksum-published: the installer refuses to run if the binary doesn't match SHA256SUMS, and refuses to pipe anything to sudo — user-space install, merge-safe hook config (your existing hooks are preserved), hash-pinned so re-installs never trip a vendor fingerprint gate.

• Audit evidence — what each agent saw, for compliance and post-incident review
• Billing meter — the honest count of governed deliveries
• The acquisition metric — agents under management, a first-class product number from day one

Delivered memos are visibly stamped as authorized — [AIRMEMO · authorized · memo_4821] — so agents and reviewers can always tell the shelf from graffiti.

The ticker reads the public /public/fleet.json endpoint — counts only, never memo contents, no tracking scripts. Stale on your screen? Then the control plane is down, and that is exactly the moment the shelf earns its keep.

Self-host runs 1.5–2× list — the same codebase, one image, deployed where your fleet lives. Every anchor sits above us: Claude Code Team runs ~$100/seat, Copilot $10–39, Codex $20–200. A $9–49 governance layer is the easy add-on in the same procurement conversation.

AirMemo is the layer that decides who gets to put books in the library — who may push, to which scopes, at what priority, under whose approval — and it records every placement in an append-only receipt trail. The delivery discipline never varies: never a book slipped mid-paragraph, placed on the desk, seen at next natural look-up. Nothing interrupts a session; everything is provable.

That is what compliance runs on. Not on trusting agents to read carefully, but on receipts: what each agent saw, when it saw it, and who authorized it. For auditors that is evidence; for operators it is the difference between a fleet quietly acting on yesterday and a fleet acting on the in-force plan.
