The News OS Revision, Reopen, and Correction Discipline Standard defines how News OS updates event packages when new evidence appears, how it avoids locking weak early interpretations into false certainty, how it keeps correction visible across versions, and how it reopens previously stable packages without collapsing the whole runtime into chaos.

That is the cleanest starting point.

If the Handoff Protocol controls how packages move outward, this page controls how packages remain honest through time.

Because one of the biggest failures in news systems is not only bad first reading.

It is bad correction behavior.

A system can begin with uncertainty honestly, then later fail because:

it hides correction
it resists reopening
it protects narrative prestige over revision
it quietly changes wording without acknowledging drift
it lets downstream systems keep using stale packages
it treats early versions as embarrassing mistakes instead of normal first-stage states

That is why this standard matters.

One-sentence answer

The News OS Revision, Reopen, and Correction Discipline Standard is the canonical update grammar that governs how event packages are corrected, versioned, downgraded, reopened, re-routed, and archived so News OS can remain honest under changing evidence without losing continuity or structural discipline.

Why this page matters

A serious runtime is not defined only by how it reads events at first contact.

It is defined by what it does when reality changes.

That is where many systems fail.

A weak system often behaves like this:

early claim enters
early narrative hardens
audience attaches emotionally
new evidence appears
correction becomes awkward
system soft-patches language
stale conclusion survives in public memory

That is a common failure corridor.

News OS is supposed to break that corridor.

So this standard exists to answer:

when should a package be revised?
when is a small correction enough?
when must the package be reopened?
when should confidence be downgraded?
how should change be logged?
what must downstream systems be told?
what belongs in archive memory after revision?

That is the real purpose of this page.

1. Canonical revision law

The revision layer must obey one main law:

a package must not preserve prestige by hiding change.

That is the core rule.

If reality changes, the package must be allowed to change.
If the package changes, that change must remain visible.
If the change is large enough, the system must reopen the event rather than quietly smoothing over the difference.

This is not weakness.

It is runtime honesty.

2. Canonical purpose of correction discipline

Correction discipline exists to preserve three things at once:

1. truth-seeking honesty

The system must remain responsive to new evidence.

2. continuity

The system must preserve what earlier versions thought, why they thought it, and why they changed.

3. downstream integrity

The system must prevent stale versions from silently poisoning handoffs, boards, classes, archives, and higher OS analysis.

That three-part balance is why correction discipline is not just editing.

It is a structural part of the runtime.

3. Canonical revision object family

Revision discipline touches several objects, but the central control objects are:

NWS_OBJ_REPORT revision state
NWS_OBJ_EVENT_CORE revision state
NWS_OBJ_GAUGE_STATE movement change
NWS_OBJ_BEP version change
NWS_OBJ_BOARD display update
NWS_OBJ_HANDOFF downstream caution propagation

A mature implementation may also define a dedicated internal correction record object, but even without a separate object, the revision logic must remain explicit across these runtime objects.

4. Core revision question

Every revision decision should answer one main question:

Does this new information merely refine the package, or does it materially change the package enough that confidence, routing, attribution, or event-core understanding must be revised openly?

That is the central decision line.

If the answer is small refinement, do a normal correction.
If the answer is structural change, reopen the package.

5. Canonical revision states

The first locked revision states should be:

UNCHANGED
MINOR_CORRECTION
MATERIAL_REVISION
REOPENED
DOWNGRADED
RETRACTED
ARCHIVE_STABLE

These states should be treated as the main revision-status grammar.

6. Meaning of the revision states

UNCHANGED

No meaningful change to the package.

This can still include formatting cleanup or non-substantive wording improvement.

MINOR_CORRECTION

A limited change that improves accuracy but does not materially alter event-core reading, confidence posture, or routing state.

Examples:

corrected timestamp
clarified actor title
refined casualty range slightly
fixed non-structural translation issue

MATERIAL_REVISION

A meaningful change that alters some important aspect of the package.

Examples:

event scope larger than first thought
a previously central claim now weakens
attribution chain changes materially
key omission now visible
confidence must be shifted

REOPENED

A previously more settled package must be actively reopened for deeper re-evaluation.

Examples:

contradiction cluster rises sharply
primary-source anchor overturns prior understanding
later evidence changes what the event fundamentally was
earlier frame dominance now clearly distorted the package

DOWNGRADED

The package must move into a weaker confidence or lattice state.

This often happens together with MATERIAL_REVISION or REOPENED.

RETRACTED

The earlier package, or a key section of it, is no longer reliable enough to stand in the same form.

This is the strongest correction state short of full object invalidation.

ARCHIVE_STABLE

The package is not beyond future change forever, but it is stable enough to serve as durable memory unless new material later forces reopening.

7. Canonical update triggers

The system should not revise randomly.
It should respond to identifiable triggers.

The first locked revision triggers are:

new primary-source evidence
major contradiction arrival
official correction
claim collapse
event-scope change
attribution shift
frame overreach exposure
omission exposure
translation or terminology correction
downstream target conflict
new time-window stabilization
false narrative lock detection

These are the core revision-trigger families.

8. Trigger 1 — new primary-source evidence

This is one of the most important triggers.

When direct evidence arrives, such as:

court text
speech transcript
signed order
official results
legal filing
raw data release

the package may need:

Event Core sharpening
claim support upgrade
claim collapse
confidence update
routing update

Not every primary source forces revision, but many important ones do.

9. Trigger 2 — major contradiction arrival

When new evidence meaningfully contradicts a central assumption, the system must respond openly.

This is one of the main reasons REOPENED exists.

A contradiction is especially important when it affects:

event identity
event cause
event timing
principal actors
main claim family
attribution chain
consequences

A contradiction at the center of the package is not a minor correction.

It is a structural event.

10. Trigger 3 — official correction

Official corrections matter, but News OS must not treat them as automatically sufficient.

An official correction is a trigger, not an unquestioned final answer.

It may lead to:

minor update
material revision
contradiction testing
stronger anchoring
or further skepticism if the official lane itself is weak

This keeps the system disciplined.

11. Trigger 4 — claim collapse

A claim collapse occurs when a previously important claim loses support.

Examples:

a viral image is misattributed
a quoted statement is false
casualty figure was inflated
one alleged actor is no longer supported by evidence
one event interpretation loses its base

When a central claim collapses, any package built heavily on that claim may need:

downgrade
reopen
rerouting of confidence
downstream caution propagation

12. Trigger 5 — event-scope change

Sometimes the event is real, but its scale changes.

Examples:

local incident becomes national issue
isolated disruption becomes regional corridor shock
“small protest” becomes wider campaign
“single strike” becomes escalation sequence

Scope changes matter because they alter:

Event Core
attribution
routing readiness
target-OS suitability
macro interpretation risk

13. Trigger 6 — attribution shift

A package may need revision even if the event core remains partially stable.

Why?

Because the blame and agency map changed.

This can happen when:

a trigger actor is reidentified
a response was misclassified as initial cause
one institution is no longer primary
scale discipline improves
early blame was overextended

Attribution shifts are especially important for:

war
politics
governance
identity-loaded events
civilisation-sensitive analysis

14. Trigger 7 — frame overreach exposure

Sometimes what changes is not the event, but the system’s awareness that one frame had become too dominant.

Examples:

a “reform” frame masked coercion
a “chaos” frame masked ordinary policy dispute
a “civilisational clash” frame overreached far beyond the event
a “humanitarian” frame hid strategic signaling, or vice versa

Frame overreach does not always alter Event Core directly, but it can require:

Frame Map revision
confidence adjustment
target-use caution
scale caution strengthening

15. Trigger 8 — omission exposure

Omission is one of the most important revision triggers.

A package may not have been “wrong” in what it said, but still deeply incomplete in what it left out.

Examples:

prior trigger event missing
treaty context missing
geography missing
legal timeline missing
affected actor set incomplete
alternative carrier evidence absent

When omission is material, the system must correct for it openly.

16. Trigger 9 — translation or terminology correction

This matters more than many systems admit.

A single mistranslation or bad category word can distort:

claim meaning
legal force
military posture
scale of event
identity attribution
civilisational reading

This is where VocabularyOS crosswalk becomes important.

A terminology correction may look small but can become structurally important.

17. Trigger 10 — downstream target conflict

Sometimes another OS receives a handoff and detects that the package is not actually strong enough for its use.

Examples:

CivOS detects scale overreach
StrategizeOS detects action posture is ahead of evidence
EducationOS detects classroom packaging would oversimplify unfairly
WarOS detects fog-of-war caution too weak

This should feed back into News OS revision discipline.

That means handoff is not one-way only.
Receiving systems can reveal correction needs too.

18. Trigger 11 — new time-window stabilization

Some revisions happen simply because the event matures.

In early hours:

uncertainty was normal

In later days:

stronger package discipline is expected

So time itself can create a revision trigger when:

first-wave claims have now stabilized
correction opportunities have matured
narrative lock can now be measured better
more anchor material is available

This is a ChronoFlight-compatible revision rule.

19. Trigger 12 — false narrative lock detection

A package may need reopening because the system detects that narrative lock formed too early.

This is especially important when:

emotional heat was high
repetition mimicked confirmation
the package rose too quickly into macro reading
one frame colonized downstream interpretation

False narrative lock is one of the biggest reasons to reopen a package even if some facts remain unchanged.

20. Canonical correction actions

Once a trigger is recognized, the system must decide what kind of action to take.

The first locked correction actions should be:

ANNOTATE
PATCH
REVISE
DOWNGRADE
REOPEN
RETRACT
PROPAGATE
ARCHIVE_UPDATE

These are the main correction actions.

21. Meaning of the correction actions

ANNOTATE

Add clarification without altering the main package state.

Useful for:

light wording refinement
non-structural caveat
new supporting note

PATCH

Correct a bounded factual or wording issue.

Useful for:

date fix
title fix
translation fix
small data correction

REVISE

Update one or more package sections materially while preserving package continuity.

Useful when:

Event Core improves
Claim Map changes
Attribution sharpens
Frame Map is rebalanced

DOWNGRADE

Lower confidence, lattice status, or routing permission.

Useful when:

stability was overstated
contradiction rose
revision risk increased

REOPEN

Re-enter full active evaluation rather than pretending previous package still holds cleanly.

Useful when:

central event-core issues destabilize
primary anchors overturn assumptions
narrative lock proved premature

RETRACT

Remove or explicitly disown a package or key component that no longer meets minimum validity.

Useful when:

core basis collapses
major misidentification occurred
package can no longer stand in prior form

PROPAGATE

Send correction state outward to downstream boards, handoffs, archives, and receiving OS targets.

This is very important.

ARCHIVE_UPDATE

Write the new version into memory while preserving prior versions and change notes.

22. Correction severity classes

A clean standard should classify corrections by severity.

Severity A — cosmetic

No structural runtime impact.

Severity B — bounded factual

Small but real factual change; package structure mostly unchanged.

Severity C — material package update

Meaningful event-package revision required.

Severity D — structural reopening

Package must be reopened and likely downgraded.

Severity E — major retraction

Prior package or central component no longer reliable enough.

This helps make revision behavior more disciplined.

23. Reopen conditions

Not every revision should reopen the package.

A package should be reopened when one or more of the following are true:

Event Core loses integrity
a major primary-source contradiction appears
attribution chain changes substantially
previously dominant claim family collapses
frame-event distinction was materially mishandled
omitted context changes the package meaning substantially
downstream action or macro analysis was built on a now-weak base

These conditions justify reopening.

24. Reopen procedure

A strong News OS should reopen in a consistent order.

Step 1

Mark current package as REOPENED.

Step 2

Downgrade confidence and lattice status if warranted.

Step 3

Identify the trigger source.

Step 4

Re-run relevant filters and plug-ins:

primary-source priority
correction trail
vocabulary precision
region/language crosswalk
scale discipline

Step 5

Rebuild:

Event Core
Claim Map
Frame Map
Attribution Cautions
Routing Recommendation

Step 6

Update board state.

Step 7

Propagate correction to downstream handoffs.

Step 8

Archive both prior and reopened versions with change explanation.

That is the canonical reopen corridor.

25. Canonical versioning rule

A revised package must not overwrite history invisibly.

The standard version rule should be:

every material package change creates a visible new version state.

A clean version line can include:

package version
revision class
timestamp
change note

Examples:

BEP_v1.0
BEP_v1.1 minor correction
BEP_v2.0 reopened
BEP_v2.1 post-reopen stabilization

This matters for trust.

26. Minimum revision log fields

Every material revision should log at least:

revision timestamp
source package version
new package version
trigger type
change severity
what changed
whether confidence changed
whether lattice state changed
whether gate output changed
whether downstream propagation occurred

This log is part of the runtime memory.

27. Board correction display rule

The board must make revision visible.

At minimum, the board should display:

current revision state
last changed time
whether event core changed
whether confidence changed
whether routing changed
whether package is reopened

If the board hides revision, users may mistake the current state for timeless stability.

28. Handoff correction propagation rule

When a handoff target has already received a package, correction discipline must not stop at the News OS boundary.

If a package is materially revised, reopened, downgraded, or retracted, the system should propagate at least:

updated version notice
new confidence state
new lattice state if changed
new caution block if strengthened
any disallowed prior use warning

This protects downstream systems from stale certainty.

29. Archive correction rule

Archive memory must preserve:

original package version
revised package version
correction trigger
change explanation
confidence and lattice change
whether archive users should prefer revised version by default

The archive must not flatten:

first version
later version
final stable version

into one memory blob.

Versioned memory is part of correction honesty.

30. Correction and lattice relationship

Correction discipline is tightly linked to lattice movement.

`+NWS_LATT -> 0NWS_LATT`

Often happens after:

material contradiction
new omission exposure
attribution weakening
reopening trigger

`0NWS_LATT -> -NWS_LATT`

Can happen if:

narrative lock was false
major claim collapse occurs
primary anchors fail
correction reveals deeper distortion

`0NWS_LATT -> +NWS_LATT`

Can happen after:

successful revision
stronger anchors
improved correction trail
claim convergence after turbulence

So revision does not only lower confidence.
It can later rebuild quality too.

31. Correction and gate relationship

Revision logic should influence gate outputs strongly.

MINOR_CORRECTION

Usually preserves gate state unless the corrected field is unexpectedly load-bearing.

MATERIAL_REVISION

May shift:

WATCH -> HOLD
ESCALATE -> WATCH
HANDOFF -> CAUTIONARY_HANDOFF or pause

REOPENED

Should usually force:

WATCH
REPAIR
DOWNGRADE
depending on severity

RETRACTED

Should usually block:

further use of prior package form
until rebuilt

This keeps gate and correction logic aligned.

32. Correction discipline by target OS

Different receiving targets need different correction sensitivity.

CivOS

Very sensitive to scale and attribution changes.
Macro-reading must be revisited quickly if source package shifts.

StrategizeOS

Very sensitive to confidence and timing changes.
Action-support packages must be corrected aggressively.

WarOS

Very sensitive to fog-of-war and attribution.
False early certainty is especially dangerous here.

EducationOS

Sensitive to fairness, simplification, and teachability.
Corrective updates should protect students from absorbing stale narratives.

CultureOS

Sensitive to symbolic overreach and identity inflation.
Small event corrections may matter greatly if prior cultural interpretation was too large.

Archive / Ledger

Sensitive to version lineage and memory integrity.
Nothing should be silently overwritten.

33. Correction invalid states

A real discipline standard must also name invalid correction behavior.

Invalid state 1

Package changes materially with no new version.

Invalid state 2

Board updates but revision reason remains invisible.

Invalid state 3

Downstream handoff not warned after material revision.

Invalid state 4

Event Core altered without confidence update.

Invalid state 5

Attribution changes materially with no scale caution update.

Invalid state 6

Retraction happens silently by deletion rather than explicit record.

Invalid state 7

Archive replaces older version with newer one and loses lineage.

Invalid state 8

Reopened package keeps prior handoff permissions without reevaluation.

Invalid state 9

Correction is framed as mere wording change when it actually alters package meaning.

These are structural failures of honesty.

34. Revision, reopen, and human trust

This page is not only technical.

It is also about trust.

A runtime earns trust not because it never changes.

It earns trust because:

it changes when needed
it shows why
it preserves continuity
it does not hide embarrassment
it does not protect prestige over correction

That is one of the deepest reasons this standard matters.

35. Revision discipline and AI legibility

This page is also very important for AI and module clarity.

Why?

Because a system becomes more machine-legible when it can show:

explicit revision states
clear trigger families
reopen rules
correction severity classes
downstream propagation
archive version lineage

Without that, an AI system may overfit to latest-state snapshots and miss the temporal truth of how the event understanding evolved.

So this standard helps News OS become not only more honest, but more runnable as a version-aware module family.

36. Final definition

The News OS Revision, Reopen, and Correction Discipline Standard is the canonical update-and-change grammar for News OS. It defines when packages must be annotated, patched, revised, downgraded, reopened, retracted, propagated, and re-archived so that new evidence can improve the system without being hidden, flattened, or allowed to corrupt downstream interpretation.
