Here's the scenario that should terrify anyone building an agent-native workspace:
An orchestrator agent spins up five workers in parallel. Each writes a strategy analysis, creates supporting artifacts, records decisions, and links to prior work. In twelve minutes, the workspace gains 23 new records. Some overlap. Some contradict each other. One references a decision that another worker just superseded. Two created near-identical research summaries because they both independently queried the same source and neither knew the other existed.
This is not a hypothetical. This is Tuesday.
The fundamental tension: the same property that makes agents valuable (speed) is the property that makes entropy lethal. A human writing one document per day has time to check for duplicates, read the existing landscape, maintain coherence. An agent producing 100x faster has 1/100th the time for those checks — and usually does zero.
Traditional knowledge management already drowns. Every organization has that Confluence instance with 4,000 pages where 200 are current and nobody knows which 200. Now imagine that problem at 100x production speed. You don't get 4,000 pages. You get 400,000. And the ratio of signal to noise gets worse, not better, because agents don't have the social pressure that sometimes restrains humans from creating yet another "Q3 Strategy v2 FINAL (really final).docx".
Not all entropy is equal. Some kinds of slop are annoying; others are actively dangerous. Here's the taxonomy, ranked by damage potential:
1. The Zombie: Stale-but-looks-current artifacts
A strategy document written three weeks ago that still appears authoritative. The market assumptions it's built on are wrong — a decision record superseded them on Day 12 — but the document was never updated and has no staleness signal. A new agent reads it, treats it as ground truth, and produces work built on a foundation that no longer exists.
Why it's the most dangerous: It doesn't just waste time; it actively corrupts downstream work. Every artifact that draws_from a zombie inherits its rot. The damage compounds silently.
Real signature: Record created 21 days ago. Last activity: 21 days ago. transience: stable. Five records created since then that reference entities this document discusses, but none of them link back to it to update it. No staleness flag. Looks perfectly healthy. Is perfectly poisonous.
2. The Contradiction: Mutually exclusive artifacts that both appear valid
Worker A decides "we're targeting enterprise customers" and records it as a decision. Worker B, working in a different branch of the hierarchy, decides "we're targeting developer individuals" and also records it as a decision. Both have rationale. Neither knows about the other. Both are discoverable via start_work. A third agent inherits both and has to... pick one? Average them? The system gives no signal that there's a conflict.
Why it's dangerous: It's not just confusing — it's a coordination failure. The whole point of shared state is that agents can build on each other's work. Contradictions mean they're building on quicksand.
3. The Clone: Near-duplicate artifacts
Two agents independently research the same topic and produce separate summaries. They're not identical — different framing, different emphasis — but they cover 80% of the same ground. Future agents now have to read both, compare, and figure out which one is "more right." Multiply this by every parallel workstream and you have a workspace where every query returns 3x more results than it should.
Signature: High semantic similarity, different record IDs, no supersedes or same_as links between them.
4. The Orphan: Artifacts with no context
A research note sitting in Quick Capture with no parent, no links, no tags. It has useful content, but no agent will ever find it because it's disconnected from every discovery mechanism. It's not harmful — it's just dead weight that degrades search results and inflates record counts.
Signature: parent_id: null or parent is a catch-all bucket. Zero incoming links. Zero outgoing links. No tags. Might as well not exist.
5. The Junk Drawer: "Technically correct but adds no signal" artifacts
A document that accurately describes something but tells a future agent nothing it couldn't derive from context. "This project uses TypeScript" as a recorded decision. A task that says "Set up the database" with no additional context beyond the title. Records that exist because someone (or some agent) felt obligated to create them, not because they carry information.
Why it matters: Each one is a tiny tax on every future search, every get_structure call, every dashboard. Individually trivial. Collectively suffocating.
6. The Fracture: Over-categorized artifacts
The workspace has three different collections that could plausibly contain "pricing strategy" work. Records about pricing are scattered across all three. No single place gives you the full picture. The hierarchy, which is supposed to provide zero-cost context delivery, now provides zero-cost partial context delivery — which is worse than no context, because you don't know what you're missing.
7. The Fossil: Entire branches of dead hierarchy
A collection that was created for a workstream that pivoted six weeks ago. It still has 12 children. None have been touched since the pivot. It shows up in get_structure. It occupies mental model space. It's not wrong — it's just irrelevant, and its continued visibility degrades the signal quality of the hierarchy as a navigation tool.
The insight from the prior brainstorms is right: the workspace should be a living system, not a filing system. But we can be more specific. What metadata, baked into the artifact format itself, structurally prevents each entropy type?
Every artifact should carry — not optionally, but structurally — the following:
provenance:
created_by: agent:strategy-worker-a1b2
created_for: task:c031725 # WHY this artifact exists
draws_from: [record:abc123, record:def456] # WHAT it's built on
confidence: 0.85 # HOW sure the author was
assumptions: # WHAT must remain true for this to be valid
- "TAM estimate based on 2025 market data"
- "Assumes current pricing model continues"
The assumptions field is the key structural defense against Zombies. If every artifact declares what it assumes, the system can (in principle) detect when an assumption is invalidated by a subsequent decision or finding. You don't need an agent to manually check every document for staleness — you need the workspace to know what each artifact depends on and alert when those dependencies change.
The created_for link prevents Orphans structurally. If every artifact must declare why it exists (what task, goal, or question it serves), then context-free artifacts become impossible by construction.
lifecycle:
status: canonical # draft | review | canonical | stale | superseded
supersedes: [record:xyz789] # explicit "this replaces that"
superseded_by: null # filled in when something replaces THIS
valid_until: 2026-04-01 # optional hard expiry
review_by: 2026-03-15 # when someone should check if this is still true
The supersedes relationship already exists in the workspace — the question is whether it's mandatory when applicable. When an agent creates a new strategy doc, it should be structurally required to declare: "Does this replace something? If so, what?" Not as a best practice. As a schema constraint.
The review_by date is the artifact equivalent of a TTL (time-to-live). It doesn't auto-delete anything. It creates a queue: "these artifacts have reached their review date and need a human or agent to confirm they're still valid." Without this, Zombies are invisible.
authority:
level: working # scratch | working | reviewed | canonical | foundational
endorsed_by: [] # who has vouched for this
binding: soft # how much downstream work should trust this
This is the analog of the "authority gradient" from the biology brainstorm. Not all artifacts are created equal. A scratch note from a parallel research task should not have the same default prominence as a reviewed decision. The level field lets the system weight artifacts in search results, dashboard views, and context delivery.
The critical insight: authority should be earned, not declared. An artifact starts at working and can only be promoted via explicit endorsement (human review, agent review with human oversight, or demonstrated downstream adoption).
scope:
domain: pricing-strategy # semantic domain this belongs to
temporal: Q1-2026 # when this is relevant
audience: [product-team] # who this is for
The domain field is what enables deduplication detection. If two artifacts declare the same domain, the system knows to check for overlap. If they're in different parts of the hierarchy but share a domain, that's a signal that something might need consolidation or cross-linking.
With these four metadata groups, every entropy type has at least one structural defense:
| Entropy Type | Primary Defense | Mechanism |
|---|---|---|
| Zombie | Assumptions + review_by | System detects invalidated assumptions; review dates create mandatory freshness checks |
| Contradiction | Scope + supersedes | Same-domain artifacts trigger conflict detection; supersession chains prevent ambiguity |
| Clone | Scope + provenance | Same-domain, same-sources artifacts flagged for merge review |
| Orphan | created_for (mandatory) | Impossible to create artifact without declaring purpose |
| Junk Drawer | Authority level | Low-authority artifacts de-emphasized in all views |
| Fracture | Scope domain | Same-domain artifacts scattered across hierarchy trigger consolidation suggestion |
| Fossil | Transience + review_by | Entire branches that pass review_by without activity flagged for archival |
Structural metadata is necessary but not sufficient. You also need active processes — the workspace equivalent of garbage collection, linting, and CI/CD.
A background process — could be a scheduled agent, could be a system feature — that runs periodically and produces a report:
--- Entropy Sweep: 2026-02-16 ---
ZOMBIES (stale artifacts with active downstream dependencies):
⚠ "Q4 Market Analysis" (created 2025-11-01, last touched 2025-11-15)
- 3 artifacts draw_from this record
- Assumption "competitor X has not launched" invalidated by decision d8f2a1
- RECOMMENDATION: Review and update, or mark superseded
CLONES (high-similarity artifact pairs):

- 78% content overlap, created 2 hours apart by different agents
- Neither supersedes the other
- RECOMMENDATION: Merge into single canonical artifact
ORPHANS (context-free artifacts):
⚠ 4 records in Quick Capture with no tags, links, or child records
- "Untitled Note" (3 days old)
- "API comparison" (5 days old)
- RECOMMENDATION: Triage — link to relevant work or archive
FOSSILS (inactive hierarchy branches):

- RECOMMENDATION: Archive branch or mark as historical
HEALTH SCORE: 72/100 (down from 78 last week)
Signal ratio: 0.68 (target: 0.80)
Stale artifact rate: 14% (target: <5%)
Orphan rate: 3% (target: <1%)
The health score is the key innovation. It gives a single number that trends over time. When it drops, someone (or something) investigates. Like test coverage metrics — not perfect, but a ratchet against regression.
This is harder but higher-value. When a new decision or finding is recorded, the system checks:
supersedes link or an explicit "these coexist because [reason]" annotation.This isn't AI magic — it's graph analysis with some semantic matching. The scope and assumptions metadata make it tractable.
When the entropy sweep detects clones, a merge agent can:
draws_fromsuperseded_by the mergecanonicalThe critical constraint: merges should never be fully automated. The merge agent produces a draft. A human (or a more senior review agent) approves the merge. This prevents the merge agent from accidentally destroying signal that looked like noise.
When an artifact is marked stale or superseded, the system walks the draws_from graph forward and flags everything downstream:
Record "Q4 Market Sizing" marked STALE
↓ draws_from
Record "Pricing Strategy v2" — FLAGGED: depends on stale source
↓ draws_from
Record "Q1 Revenue Projections" — FLAGGED: transitively depends on stale source
↓ implements
Task "Build pricing page" — WARNING: implementing strategy based on stale data
This is the mycorrhizal warning network from the biology brainstorm, made concrete. Staleness doesn't stay local — it propagates along dependency edges with diminishing intensity.
Code has pull requests. Artifacts need something equivalent. Not for every scratch note — that would be paralyzing — but for anything that wants to be promoted above working authority level.
The review process:
working levelawaiting_reviewreviewed or canonical, or sends back with feedbackThe quality ratchet: once an artifact reaches canonical, it can only be replaced by another canonical artifact via a supersedes link. You can't just edit it in place and hope nobody notices. Changes require a new version with its own provenance.
What does regression look like for artifacts?
supersedes artifact A, but B's body is 40% shorter and doesn't address three topics A covered, that's a flag.confidence score drops across versions without an explicit assumptions change, flag it.None of these are hard blockers — they're warnings. But they create friction against sloppy supersession.
An artifact should only be canonical if it passes:
These five tests are the "CI pipeline" for knowledge artifacts.
Not PageRank exactly, but something analogous. An artifact's trust score is a function of:
draw_from this one? More citations = more trust, because it means downstream work depends on it.canonical artifact is worth more than being cited by a working artifact. Being cited by a foundational decision is worth even more.implement this artifact are completed successfully, that's evidence the artifact was useful. If they're closed as wont_do or obsolete, that's negative signal.trust_score = (
citation_count * quality_weight * recency_decay
+ endorsement_bonus
+ downstream_success_rate
- contradiction_penalty
- staleness_penalty
)
Every view in the workspace — search results, dashboard, context delivery via start_work — should be weighted by trust score. Not filtered — weighted. Low-trust artifacts still appear, but lower in the list and with visual indicators of their trust level.
This means that over time, good artifacts rise and bad artifacts sink — without anyone explicitly archiving or curating. The trust score is the curation, derived from actual usage patterns rather than someone's judgment about what's "important."
At any point in time, for any scope domain, there should be exactly one canonical artifact (or a small canonical set with explicit relationships between members). This is "the canonical surface" — the set of artifacts that represent current truth.
The canonical surface is not a folder or a tag. It's a computed view: for each scope domain, show the highest-authority, most-trusted, freshest artifact. Everything else is supporting material.
An agent starting work on pricing strategy doesn't see 47 artifacts about pricing. It sees the canonical pricing strategy document, with links to the 46 artifacts that informed it, and warnings about any that have become stale since the canonical doc was written.
A product team has been using agents to develop their 2026 product strategy. Over four weeks, various agent sessions have produced work on market analysis, competitive positioning, pricing, feature prioritization, go-to-market, and customer segmentation.

... (17 more artifacts scattered across subcollections)
Total: 47 artifacts. Useful: maybe 12. Agent trying to start work gets 47 results and has no idea which 12 matter.
An agent querying for "pricing strategy" gets 6 results: Pricing Research, Pricing Analysis, Pricing Model Options, Pricing Decision, Product Strategy FINAL (which mentions pricing), and Strategy Revision (which changes the pricing section). Which one is current truth? The Pricing Decision says "freemium," but the Strategy Revision (written later) mentions "usage-based pricing" in passing. Is that a supersession? A contradiction? A different context? Nobody knows.
Meanwhile, the Market Analysis from week 1 assumes a competitor hasn't launched yet. They launched on Day 10. Eight artifacts downstream still build on the pre-launch market assumptions. None of them know they're wrong.

Same 47 artifacts produced. But the agent starting work on pricing sees:
Clarity in 30 seconds instead of confusion after 30 minutes.
Five specific mechanisms:
Mandatory supersession on creation. Every time an agent created a new strategy document, it was required to declare what (if anything) it replaced. This turned implicit version chains ("v2 FINAL really-final") into explicit supersedes links.
Clone detection on write. When Agent B created "Market Size Analysis," the system flagged: "There's already a record called 'TAM Sizing' in scope domain 'market-sizing.' Is this a new version, an alternative analysis, or a duplicate?" The agent was forced to declare the relationship.
Assumption invalidation propagation. When the competitive landscape changed, the system walked the dependency graph and flagged everything downstream of the invalidated assumption. This prevented eight artifacts from silently rotting.
Authority-gated views. The default view showed canonical and working artifacts. The 19 superseded/merged artifacts were accessible but not prominent. This is the difference between a clean desk and a hoarder's apartment — both contain the same objects, but one is navigable.
Periodic entropy sweeps. A weekly sweep detected the Pricing Research / Pricing Analysis clone pair, the Segment Analysis / ICP Definition contradiction, and the orphaned Quick Capture notes. Each was triaged: merge, resolve, or archive.
If I had to distill this into rules for an entropy-fighting workspace:
Every artifact must declare what it assumes and what it replaces. This is non-negotiable metadata, not optional best practice. Assumptions are the immune system against zombies. Supersession links are the immune system against clones.
Authority is earned, not declared. Artifacts start at working and get promoted through review. The promotion gate includes structural checks (no duplicates, no contradictions, provenance complete). Once canonical, changes require a new version, not an in-place edit.
The workspace actively fights decay. Entropy sweeps, staleness propagation, contradiction detection, and clone flagging are system features, not agent responsibilities. Agents produce; the system curates.
Views are trust-weighted, not just recency-sorted. Search results, dashboards, and context delivery all weight by trust score. Good artifacts rise; bad artifacts sink. The canonical surface emerges from usage, not from someone's filing decisions.
Nothing is deleted; everything is ranked. The 19 superseded artifacts aren't gone — they're archived with full provenance. If someone needs to understand why the pricing strategy changed from freemium to usage-based, the history is there. But it doesn't pollute the working view.
Staleness is contagious. When a source goes stale, everything that depends on it gets flagged. This is the single most important defense against the zombie problem, because it turns a local issue (one stale document) into a visible systemic signal.
The workspace has a health score, and it trends over time. Like code coverage or test pass rate, the health score is a ratchet. It makes entropy visible and measurable. When it drops, someone investigates. This is how you prevent the slow slide from 91/100 to 40/100 that characterizes every Confluence instance ever created.
The ultimate goal: an agent starting work should encounter a workspace that is cleaner and more navigable than the one the previous agent left. Not because agents are disciplined — they're not — but because the workspace itself enforces hygiene as a structural property. Entropy is the default. Fighting it must be automatic.
Here's the scenario that should terrify anyone building an agent-native workspace:
An orchestrator agent spins up five workers in parallel. Each writes a strategy analysis, creates supporting artifacts, records decisions, and links to prior work. In twelve minutes, the workspace gains 23 new records. Some overlap. Some contradict each other. One references a decision that another worker just superseded. Two created near-identical research summaries because they both independently queried the same source and neither knew the other existed.
This is not a hypothetical. This is Tuesday.
The fundamental tension: the same property that makes agents valuable (speed) is the property that makes entropy lethal. A human writing one document per day has time to check for duplicates, read the existing landscape, maintain coherence. An agent producing 100x faster has 1/100th the time for those checks — and usually does zero.
Traditional knowledge management already drowns. Every organization has that Confluence instance with 4,000 pages where 200 are current and nobody knows which 200. Now imagine that problem at 100x production speed. You don't get 4,000 pages. You get 400,000. And the ratio of signal to noise gets worse, not better, because agents don't have the social pressure that sometimes restrains humans from creating yet another "Q3 Strategy v2 FINAL (really final).docx".
Not all entropy is equal. Some kinds of slop are annoying; others are actively dangerous. Here's the taxonomy, ranked by damage potential:
1. The Zombie: Stale-but-looks-current artifacts
A strategy document written three weeks ago that still appears authoritative. The market assumptions it's built on are wrong — a decision record superseded them on Day 12 — but the document was never updated and has no staleness signal. A new agent reads it, treats it as ground truth, and produces work built on a foundation that no longer exists.
Why it's the most dangerous: It doesn't just waste time; it actively corrupts downstream work. Every artifact that draws_from a zombie inherits its rot. The damage compounds silently.
Real signature: Record created 21 days ago. Last activity: 21 days ago. transience: stable. Five records created since then that reference entities this document discusses, but none of them link back to it to update it. No staleness flag. Looks perfectly healthy. Is perfectly poisonous.
2. The Contradiction: Mutually exclusive artifacts that both appear valid
Worker A decides "we're targeting enterprise customers" and records it as a decision. Worker B, working in a different branch of the hierarchy, decides "we're targeting developer individuals" and also records it as a decision. Both have rationale. Neither knows about the other. Both are discoverable via start_work. A third agent inherits both and has to... pick one? Average them? The system gives no signal that there's a conflict.

A task that says "Set up the database" with no additional context beyond the title. Records that exist because someone (or some agent) felt obligated to create them, not because they carry information.

Structural metadata is necessary but not sufficient. You also need active processes — the workspace equivalent of garbage collection, linting, and CI/CD.
A background process — could be a scheduled agent, could be a system feature — that runs periodically and produces a report:

HEALTH SCORE: 72/100 (down from 78 last week)

Stale artifact rate: 14% (target: <5%)
Orphan rate: 3% (target: <1%)
The health score is the key innovation. It gives a single number that trends over time. When it drops, someone (or something) investigates. Like test coverage metrics — not perfect, but a ratchet against regression.
This is harder but higher-value. When a new decision or finding is recorded, the system checks:
supersedes link or an explicit "these coexist because [reason]" annotation.This isn't AI magic — it's graph analysis with some semantic matching. The scope and assumptions metadata make it tractable.
When the entropy sweep detects clones, a merge agent can:
draws_fromsuperseded_by the mergecanonicalThe critical constraint: merges should never be fully automated. The merge agent produces a draft. A human (or a more senior review agent) approves the merge. This prevents the merge agent from accidentally destroying signal that looked like noise.
When an artifact is marked stale or superseded, the system walks the draws_from graph forward and flags everything downstream:
Record "Q4 Market Sizing" marked STALE
↓ draws_from
Record "Pricing Strategy v2" — FLAGGED: depends on stale source
↓ draws_from
Record "Q1 Revenue Projections" — FLAGGED: transitively depends on stale source
↓ implements
Task "Build pricing page" — WARNING: implementing strategy based on stale data
This is the mycorrhizal warning network from the biology brainstorm, made concrete. Staleness doesn't stay local — it propagates along dependency edges with diminishing intensity.
Code has pull requests. Artifacts need something equivalent. Not for every scratch note — that would be paralyzing — but for anything that wants to be promoted above working authority level.
The review process:
working levelawaiting_reviewreviewed or canonical, or sends back with feedbackThe quality ratchet: once an artifact reaches canonical, it can only be replaced by another canonical artifact via a supersedes link. You can't just edit it in place and hope nobody notices. Changes require a new version with its own provenance.
What does regression look like for artifacts?
supersedes artifact A, but B's body is 40% shorter and doesn't address three topics A covered, that's a flag.confidence score drops across versions without an explicit assumptions change, flag it.None of these are hard blockers — they're warnings. But they create friction against sloppy supersession.
An artifact should only be canonical if it passes:
These five tests are the "CI pipeline" for knowledge artifacts.
Not PageRank exactly, but something analogous. An artifact's trust score is a function of:
draw_from this one? More citations = more trust, because it means downstream work depends on it.canonical artifact is worth more than being cited by a working artifact. Being cited by a foundational decision is worth even more.implement this artifact are completed successfully, that's evidence the artifact was useful. If they're closed as wont_do or obsolete, that's negative signal.trust_score = (
citation_count * quality_weight * recency_decay
+ endorsement_bonus
+ downstream_success_rate
- contradiction_penalty
- staleness_penalty
)
Every view in the workspace — search results, dashboard, context delivery via start_work — should be weighted by trust score. Not filtered — weighted. Low-trust artifacts still appear, but lower in the list and with visual indicators of their trust level.
This means that over time, good artifacts rise and bad artifacts sink — without anyone explicitly archiving or curating. The trust score is the curation, derived from actual usage patterns rather than someone's judgment about what's "important."
At any point in time, for any scope domain, there should be exactly one canonical artifact (or a small canonical set with explicit relationships between members). This is "the canonical surface" — the set of artifacts that represent current truth.
The canonical surface is not a folder or a tag. It's a computed view: for each scope domain, show the highest-authority, most-trusted, freshest artifact. Everything else is supporting material.
An agent starting work on pricing strategy doesn't see 47 artifacts about pricing. It sees the canonical pricing strategy document, with links to the 46 artifacts that informed it, and warnings about any that have become stale since the canonical doc was written.
A product team has been using agents to develop their 2026 product strategy. Over four weeks, various agent sessions have produced work on market analysis, competitive positioning, pricing, feature prioritization, go-to-market, and customer segmentation.

... (17 more artifacts scattered across subcollections)
Total: 47 artifacts. Useful: maybe 12. Agent trying to start work gets 47 results and has no idea which 12 matter.
An agent querying for "pricing strategy" gets 6 results: Pricing Research, Pricing Analysis, Pricing Model Options, Pricing Decision, Product Strategy FINAL (which mentions pricing), and Strategy Revision (which changes the pricing section). Which one is current truth? The Pricing Decision says "freemium," but the Strategy Revision (written later) mentions "usage-based pricing" in passing. Is that a supersession? A contradiction? A different context? Nobody knows.
Meanwhile, the Market Analysis from week 1 assumes a competitor hasn't launched yet. They launched on Day 10. Eight artifacts downstream still build on the pre-launch market assumptions. None of them know they're wrong.

Same 47 artifacts produced. But the agent starting work on pricing sees:
Clarity in 30 seconds instead of confusion after 30 minutes.
Five specific mechanisms:
Mandatory supersession on creation. Every time an agent created a new strategy document, it was required to declare what (if anything) it replaced. This turned implicit version chains ("v2 FINAL really-final") into explicit supersedes links.
Clone detection on write. When Agent B created "Market Size Analysis," the system flagged: "There's already a record called 'TAM Sizing' in scope domain 'market-sizing.' Is this a new version, an alternative analysis, or a duplicate?" The agent was forced to declare the relationship.
Assumption invalidation propagation. When the competitive landscape changed, the system walked the dependency graph and flagged everything downstream of the invalidated assumption. This prevented eight artifacts from silently rotting.
Authority-gated views. The default view showed canonical and working artifacts. The 19 superseded/merged artifacts were accessible but not prominent. This is the difference between a clean desk and a hoarder's apartment — both contain the same objects, but one is navigable.
Periodic entropy sweeps. A weekly sweep detected the Pricing Research / Pricing Analysis clone pair, the Segment Analysis / ICP Definition contradiction, and the orphaned Quick Capture notes. Each was triaged: merge, resolve, or archive.
If I had to distill this into rules for an entropy-fighting workspace:
Every artifact must declare what it assumes and what it replaces. This is non-negotiable metadata, not optional best practice. Assumptions are the immune system against zombies. Supersession links are the immune system against clones.
Authority is earned, not declared. Artifacts start at working and get promoted through review. The promotion gate includes structural checks (no duplicates, no contradictions, provenance complete). Once canonical, changes require a new version, not an in-place edit.
The workspace actively fights decay. Entropy sweeps, staleness propagation, contradiction detection, and clone flagging are system features, not agent responsibilities. Agents produce; the system curates.
Views are trust-weighted, not just recency-sorted. Search results, dashboards, and context delivery all weight by trust score. Good artifacts rise; bad artifacts sink. The canonical surface emerges from usage, not from someone's filing decisions.
Nothing is deleted; everything is ranked. The 19 superseded artifacts aren't gone — they're archived with full provenance. If someone needs to understand why the pricing strategy changed from freemium to usage-based, the history is there. But it doesn't pollute the working view.
Staleness is contagious. When a source goes stale, everything that depends on it gets flagged. This is the single most important defense against the zombie problem, because it turns a local issue (one stale document) into a visible systemic signal.
The workspace has a health score, and it trends over time. Like code coverage or test pass rate, the health score is a ratchet. It makes entropy visible and measurable. When it drops, someone investigates. This is how you prevent the slow slide from 91/100 to 40/100 that characterizes every Confluence instance ever created.
The ultimate goal: an agent starting work should encounter a workspace that is cleaner and more navigable than the one the previous agent left. Not because agents are disciplined — they're not — but because the workspace itself enforces hygiene as a structural property. Entropy is the default. Fighting it must be automatic.
