# ic-memory documentation
The documents in this directory serve different audiences. Use this index to
distinguish current integration guidance from historical engineering evidence.
## Start here
- [Project overview and quick start](../README.md) explains in plain language
what `ic-memory` protects, when it is useful, and how to integrate it.
- [Frequently asked questions](../README.md#frequently-asked-questions) answers
common scope, lifecycle, retirement, and allocation-style questions.
- [Advanced integration](../ADVANCED.md) covers runtime ownership, custom
policies, range authority, recovery, and manual bootstrap.
- [Safety invariants](../SAFETY.md) defines the properties that implementation
changes must preserve.
## Current focused guides
- [Operations and diagnostics](operations.md) explains allocation reports,
bucket configuration, doctor reports, and growth failures.
- [Troubleshooting](troubleshooting.md) maps common symptoms and typed errors
to safe next actions without resetting durable state.
- [Key-only allocation and bounded recovery](key-only-recovery.md) defines
automatic placement, host adoption, omitted-store inspection, and recovery
limits.
- [Recovered-metadata admission](recovered-admission.md) defines how a host can
select known historical stores before committing one bootstrap generation.
When current guides disagree, the crate's public API and safety invariants are
authoritative. This project is pre-1.0 and maintains only its current API and
durable format.
The package version is declared in [Cargo.toml](../Cargo.toml); current guides
describe the maintained implementation without separate release stamps.
Historical qualification records retain the exact versions and source snapshots
they checked.
## Integration and qualification records
These documents record specific consumer source snapshots, environments, and
test results. They are evidence for the versions named in each document, not a
promise that a later consumer graph or deployment was requalified.
- [Issue reconciliation](issue-reconciliation.md)
- [Canic checked-slot qualification for 0.25.0](consumer-qualification-0.25.0-canic.md)
- [Canic memory qualification for 0.24.6](consumer-qualification-0.24.6-canic.md)
- [IcyDB qualification for 0.24.4](consumer-qualification-0.24.4.md)
- [IcyDB qualification for 0.24.3](consumer-qualification-0.24.3.md)
- [Consumer qualification for 0.20.0](consumer-qualification-0.20.0.md)
## Historical design and measurement records
These reports explain why earlier changes were made and retain their original
measurements. Use the current guides above for present-day API instructions.
- [CANIC-162 physical allocation study](canic162-memory-attribution.md)
- [Opaque ledger payload encoding](opaque-ledger-payloads.md)
- [Logical bootstrap cleanup](logical-bootstrap-cleanup.md)
- [Wasm codec size audit](audits/wasm-codec-size-2026-07-14.md)
- [Recurring audit records](audits/recurring/)
Measurement CSVs under `measurements/` belong to the historical reports that
link to them.

### Documentation release checklist
Before publishing a release that changes the API, durable format, terminology,
or workflow:
- update the crate version and README dependency example together;
- update examples, diagrams, captions, and alt text when terminology changes;
- run doctests with warnings denied;
- verify every local Markdown link and heading anchor;
- confirm current guidance does not retain a superseded pre-1.0 API or wire
shape; and
- keep historical measurements and qualification claims labeled with their
original version and scope.
