ironshard.branch, snapshots + forks

Snapshot any bucket
Branch it instantly
Recover anything

Copying a bucket to experiment is slow and expensive. Overwrite production and the old state is gone. Ad-hoc copies leave no record of what ran, or who promoted it. Branch fixes all three, without touching the source.

How snapshots, copy-on-write branches, and merges work: the Branching and Snapshots docs.

How Branch works Immutable snapshots accrue down a main timeline. A writable branch forks from a snapshot, takes a new write and diverges, while point-in-time recovery reads back from any snapshot. mainrestore to any snapshotfork →experimentnew write — diverges snapshots accrue on main · branches diverge and take writes · recover from any point
// how it works

Snapshot, branch, experiment, promote

The source is never touched, and every action is logged automatically.

01

Snapshot — immutable, instant

Capture a bucket’s exact state at a point in time. Zero-copy, instant, and read-only — it never changes.

instant · immutable
02

Branch a writable fork

Fork from any snapshot or live state. Copy-on-write, so storage is zero until the branch diverges.

zero-copy until divergence
03

Experiment in isolation

Run pipelines, migrations, or training against the branch. Many branches run in parallel; the source is untouched.

parallel · isolated
04

Promote or discard. Log is automatic.

Promote through a governed workflow or discard at zero cost. Every action is written to an immutable log.

governed · audit-logged
// workflows

A safe workspace for anything

Spin up an isolated branch, run a job, check the results, then promote or discard. Nothing touches the source until you say so.

Nothing ships unreviewedWho signs off is up to you

When the work is done, IronShard shows exactly what changed: added, modified, removed, plus cost and policy impact. Promote automatically when policy checks pass, or require a human sign-off.

Review and promote A branch arrives at a review window summarizing what changed. It is then promoted, kept as an artifact, or discarded, automatically by policy or after human sign-off. branchreview+ 128 new~ 34 modified− 12 removed✓ policy · approvalsest. cost +$0.40Promotemerge back · or managed bucketKeepaudit artifact · or exportDiscardzero cost · production untouched
Agents experiment on branches. Production lives in managed buckets.

What this makes possible

Agent sandboxing

Give an autonomous agent its own branch to read, write, and delete freely. If a run goes wrong, discard it at zero cost. Production is never exposed.

autonomous · fully isolated

Shadow testing

Run a new model or agent against real data on a branch, side by side with production. Compare outputs and promote only the version that wins.

real data · zero production risk

Recovery & reproducibility

Return to any past state. Restore a bucket to the moment before a bad write or deletion, or pin an exact snapshot so a result reproduces no matter how much the source has moved on.

point-in-time · reproducible

Audit & compliance

Every change on a branch is recorded immutably: what an agent read, what it wrote, and who promoted it. A tamper-evident trail you can hand to a regulator.
