v0.11 item 3: retention gets a page, and postgres.md's claim is closed - #34
Conversation
postgres.md has said since v0.6 that this library has no retention policy, in the same breath as the reason one is hard. That is the claim item 3 pays. The retention page states two things the ROADMAP line did not: the ledger rule is settlement and then a window rather than 'un-released', and the window is supplied on the command line rather than derived, because a store that resolved a grant's budgets would be reading the policy.

Align the command citations in this claims row.
The row names deny but cites effects, so the citation does not support the stated command. docs/CLAIMS.md:104 identifies stats at cli/main.py:1326, while this row cites cli/main.py:1074. Use the current deny definition and align the stats citation with the documented location.

Document both required prune options and their separate roles.
--through is a supported required option for the public ctrlrun prune command. --older-than is also required; it guards committed ledger rows and does not convert into a receipt sequence cutoff. Update this invocation to include both options and explain that --through selects the receipt prefix while --older-than supplies the ledger retention window.

Complete the refusal summary.
docs/OWASP-AGENTIC-TOP10.md G29 also refuses a prune that moves the checkpoint backwards. docs/ROADMAP.md states that a COMMITTED ledger row is prunable only outside the §7.3 window. This paragraph omits both conditions while listing the prune refusals. Add them or state that the list is non-exhaustive.

Pairs with CTRLRun/ctrlrun#203, on a branch of the same name. v0.11 item 3: retention.
The claim this closes
docs/postgres.mdhas said since v0.6 that this library does not prune, roll or retain, in the same breath as the reason one is hard: deleting receipts from the middle or the end of the chain is detected as a break by design.SPEC-v0.11.md§4 opens by citing that sentence, and this is the edit that pays it.It is narrowed rather than deleted. Events, approvals, delegations and continuations still grow without bound, and nothing runs in the background. Receipts are the exception, and the page says which.
A new page:
docs/production/retention.mdxWhat to run, what is refused, and what it does not do. Two things it states that the ROADMAP line did not, both settled during the build:
COMMITTEDholds permanently and onlyFAILEDreleases, so "un-released" would have been almost every row forever and the feature would have done nothing. ACOMMITTEDrow is prunable only outside the budget window, because pruning one inside it hands back authority nobody granted.Chargefrom the authority document, and a store that resolved them would be reading the policy. So--older-thanis the operator's number, and the page says which number to use: the longest window on any budget of any grant.The page's "What this does not do" is the part worth reading. It says that a prune destroys evidence, that a checkpoint row is forgeable by anyone who can insert receipts and the anchor is what narrows that, that nothing runs on a schedule and no hold expires, and that retention is deliberately not in the policy document — because a policy key would make pruning subject to
require_approved_policy, and a deployment that had not approved its current policy could then never prune.G29,G30andG32inOWASP-AGENTIC-TOP10.mdEach with its row and its limits.
G30's is the one to check: a hold bindsctrlrun prune, notDELETE, and it does not stop anyone with database access from deleting rows directly.G32's row explains why the pair needs a guarantee of its own:G28grades a truncation against an anchor andG29grades a prune against the chain, and the interaction — an honest prune leaving the anchor report clean — was graded by neither. Without it, every anchor older than the retention window would be permanentlyanchor_broken.Generated
